public class MonetPreparedStatement
extends MonetStatement
implements PreparedStatement, AutoCloseable
A PreparedStatement suitable for the MonetDB database. This implementation of the PreparedStatement interface uses the capabilities of the MonetDB/SQL backend to prepare and execute statements. The backend takes care of finding the '?'s in the input and returns the types it expects for them. An example of a server response on a prepare query is: 
 % prepare select name from tables where id > ? and id < ?;
 &5 0 2 3 2
 # prepare,      prepare,        prepare # table_name
 # type, digits, scale # name
 # varchar,      int,    int # type
 # 0,    0,      0 # length
 [ "int",        9,      0       ]
 [ "int",        9,      0       ]

  • Method Details

    • addBatch

      public void addBatch() throws SQLException
      Adds a set of parameters to this PreparedStatement object's batch of commands.
      Specified by:
      addBatch in interface PreparedStatement
      Throws:
      SQLException - if a database access error occurs

    • addBatch

      public void addBatch​(String q) throws SQLException
      override the addBatch from the Statement to throw an SQLException
      Specified by:
      addBatch in interface Statement
      Overrides:
      addBatch in class MonetStatement
      Parameters:
      q - typically this is a static SQL INSERT or UPDATE statement
      Throws:
      SQLException - so the PreparedStatement can throw this exception

    • clearParameters

      public void clearParameters()
      Clears the current parameter values immediately. In general, parameter values remain in force for repeated use of a statement. Setting a parameter value automatically clears its previous value. However, in some cases it is useful to immediately release the resources used by the current parameter values; this can be done by calling the method clearParameters.
      Specified by:
      clearParameters in interface PreparedStatement

    • execute

      public boolean execute() throws SQLException
      Executes the SQL statement in this PreparedStatement object, which may be any kind of SQL statement. Some prepared statements return multiple results; the execute method handles these complex statements as well as the simpler form of statements handled by the methods executeQuery and executeUpdate. The execute method returns a boolean to indicate the form of the first result. You must call either the method getResultSet or getUpdateCount to retrieve the result; you must call getMoreResults to move to any subsequent result(s).
      Specified by:
      execute in interface PreparedStatement
      Returns:
      true if the first result is a ResultSet object; false if the first result is an update count or there is no result
      Throws:
      SQLException - if a database access error occurs or an argument is supplied to this method

    • execute

      public boolean execute​(String q) throws SQLException
      override the execute from the Statement to throw an SQLException
      Specified by:
      execute in interface Statement
      Overrides:
      execute in class MonetStatement
      Parameters:
      q - any SQL statement
      Returns:
      true if the first result is a ResultSet object; false if it is an update count or there are no results
      Throws:
      SQLException - if a database access error occurs

    • executeQuery

      public ResultSet executeQuery() throws SQLException
      Executes the SQL query in this PreparedStatement object and returns the ResultSet object generated by the query.
      Specified by:
      executeQuery in interface PreparedStatement
      Returns:
      a ResultSet object that contains the data produced by the query; never null
      Throws:
      SQLException - if a database access error occurs or the SQL statement does not return a ResultSet object

    • executeQuery

      public ResultSet executeQuery​(String q) throws SQLException
      override the executeQuery from the Statement to throw an SQLException
      Specified by:
      executeQuery in interface Statement
      Overrides:
      executeQuery in class MonetStatement
      Parameters:
      q - an SQL statement to be sent to the database, typically a static SQL SELECT statement
      Returns:
      a ResultSet object that contains the data produced by the given query; never null
      Throws:
      SQLException - if a database access error occurs or the given SQL statement produces anything other than a single ResultSet object

    • executeUpdate

      public int executeUpdate() throws SQLException
      Executes the SQL statement in this PreparedStatement object, which must be an SQL INSERT, UPDATE or DELETE statement; or an SQL statement that returns nothing, such as a DDL statement.
      Specified by:
      executeUpdate in interface PreparedStatement
      Returns:
      either (1) the row count for INSERT, UPDATE, or DELETE statements or (2) 0 for SQL statements that return nothing
      Throws:
      SQLException - if a database access error occurs or the SQL statement returns a ResultSet object

    • executeUpdate

      public int executeUpdate​(String q) throws SQLException
      override the executeUpdate from the Statement to throw an SQLException
      Specified by:
      executeUpdate in interface Statement

      SQLException - if a database access error occurs or the given SQL statement produces a ResultSet object

    • getMetaData

      public ResultSetMetaData getMetaData() throws SQLException
      Retrieves a ResultSetMetaData object that contains information about the columns of the ResultSet object that will be returned when this PreparedStatement object is executed. Because a PreparedStatement object is precompiled, it is possible to know about the ResultSet object that it will return without having to execute it. Consequently, it is possible to invoke the method getMetaData on a PreparedStatement object rather than waiting to execute it and then invoking the ResultSet.getMetaData method on the ResultSet object that is returned.
      Specified by:
      getMetaData in interface PreparedStatement
      Returns:
      the description of a ResultSet object's columns or null if the driver cannot return a ResultSetMetaData object
      Throws:
      SQLException - if a database access error occurs

    • getParameterMetaData

      public ParameterMetaData getParameterMetaData() throws SQLException
      Retrieves the number, types and properties of this PreparedStatement object's parameters.
      Specified by:
      getParameterMetaData in interface PreparedStatement
      Returns:
      a ParameterMetaData object that contains information about the number, types and properties of this PreparedStatement object's parameters
      Throws:
      SQLException - if a database access error occurs

    • setArray

      public void setArray​(int parameterIndex, Array x) throws SQLException

      Sets the designated parameter to a Reader object. The Reader reads the data till end-of-file is reached. The driver does the necessary conversion from Java character format to the national character set in the database.
      Specified by:
      setNCharacterStream in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      value - the parameter value
      length - the number of characters in the parameter data.
      Throws:
      SQLException - if a database access error occurs

    • setNClob

      public void setNClob​(int parameterIndex, Reader value) throws SQLException
      Sets the designated parameter to a java.sql.NClob object. The driver converts this to a SQL NCLOB value when it sends it to the database.
      Specified by:
      setNClob in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      value - the parameter value
      Throws:
      SQLException - if a database access error occurs
      SQLFeatureNotSupportedException - the JDBC driver does not support this method

    • setNClob

      public void setNClob​(int parameterIndex, NClob value) throws SQLException
      Sets the designated parameter to a java.sql.NClob object. The driver converts this to a SQL NCLOB value when it sends it to the database.
      Specified by:
      setNClob in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      value - the parameter value
      Throws:
      SQLException - if a database access error occurs
      SQLFeatureNotSupportedException - the JDBC driver does not support this method

    • setNClob

      public void setNClob​(int parameterIndex, Reader r, long length) throws SQLException
      Sets the designated parameter to a Reader object. The reader must contain the number of characters specified by length otherwise a SQLException will be generated when the PreparedStatement is executed. This method differs from the setCharacterStream (int, Reader, int) method because it informs the driver that the parameter value should be sent to the server as a NCLOB. When the setCharacterStream method is used, the driver may have to do extra work to determine whether the parameter data should be sent to the server as a LONGNVARCHAR or a NCLOB.
      Specified by:
      setNClob in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      r - An object that contains the data to set the parameter value to
      length - the number of characters in the parameter data
      Throws:
      SQLException - if a database access error occurs
      SQLFeatureNotSupportedException - the JDBC driver does not support this method

    • setNString

      public void setNString​(int parameterIndex, String value) throws SQLException
      Sets the designated paramter to the given String object. The driver converts this to a SQL NCHAR or NVARCHAR or LONGNVARCHAR value (depending on the argument's size relative to the driver's limits on NVARCHAR values) when it sends it to the database.
      Specified by:
      setNString in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      value - the parameter value
      Throws:
      SQLException - if a database access error occurs

    • setNull

      public void setNull​(int parameterIndex, int sqlType) throws SQLException
      Sets the designated parameter to SQL NULL. Note: You must specify the parameter's SQL type.
      Specified by:
      setNull in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      sqlType - the SQL type code defined in java.sql.Types
      Throws:
      SQLException - if a database access error occurs

    • setNull

      public void setNull​(int parameterIndex, int sqlType, String typeName) throws SQLException
      Sets the designated parameter to SQL NULL. This version of the method setNull should be used for user-defined types and REF type parameters. Examples of user-defined types include: STRUCT, DISTINCT, JAVA_OBJECT, and named array types. Note: To be portable, applications must give the SQL type code and the fully-qualified SQL type name when specifying a NULL user-defined or REF parameter. In the case of a user-defined type the name is the type name of the parameter itself. For a REF parameter, the name is the type name of the referenced type. If a JDBC driver does not need the type code or type name information, it may ignore it. Although it is intended for user-defined and Ref parameters, this method may be used to set a null parameter of any JDBC type. If the parameter does not have a user-defined or REF type, the given typeName is ignored.
      Specified by:
      setNull in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      sqlType - a value from java.sql.Types
      typeName - the fully-qualified name of an SQL user-defined type; ignored if the parameter is not a user-defined type or REF
      Throws:
      SQLException - if a database access error occurs

    • setObject

      public void setObject​(int parameterIndex, Object x) throws SQLException
      Sets the value of the designated parameter using the given object. The second parameter must be of type Object; therefore, the java.lang equivalent objects should be used for built-in types. The JDBC specification specifies a standard mapping from Java Object types to SQL types. The given argument will be converted to the corresponding SQL type before being sent to the database. Note that this method may be used to pass datatabase-specific abstract data types, by using a driver-specific Java type. If the object is of a class implementing the interface SQLData, the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type. This method throws an exception if there is an ambiguity, for example, if the object is of a class implementing more than one of the interfaces named above.
      Specified by:
      setObject in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      x - the object containing the input parameter value
      Throws:
      SQLException - if a database access error occurs or the type of the given object is ambiguous

    • setObject

      public void setObject​(int parameterIndex, Object x, int targetSqlType) throws SQLException
      Sets the value of the designated parameter with the given object. This method is like the method setObject below, except that it assumes a scale of zero.
      Specified by:
      setObject in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      x - the object containing the input parameter value
      targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database
      Throws:
      SQLException - if a database access error occurs

    • setObject

      public void setObject​(int parameterIndex, Object x, int targetSqlType, int scale) throws SQLException
      Sets the value of the designated parameter with the given object. The second argument must be an object type; for integral values, the java.lang equivalent objects should be used. The given Java object will be converted to the given targetSqlType before being sent to the database. If the object has a custom mapping (is of a class implementing the interface SQLData), the JDBC driver should call the method SQLData.writeSQL to write it to the SQL data stream. If, on the other hand, the object is of a class implementing Ref, Blob, Clob, Struct, or Array, the driver should pass it to the database as a value of the corresponding SQL type. Note that this method may be used to pass database-specific abstract data types. To meet the requirements of this interface, the Java object is converted in the driver, instead of using a SQL CAST construct.
      Specified by:
      setObject in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      x - the object containing the input parameter value
      targetSqlType - the SQL type (as defined in java.sql.Types) to be sent to the database. The scale argument may further qualify this type.
      scale - for java.sql.Types.DECIMAL or java.sql.Types.NUMERIC types, this is the number of digits after the decimal point. For Java Object types InputStream and Reader, this is the length of the data in the stream or reader. For all other types, this value will be ignored.
      Throws:
      SQLException - if a database access error occurs
      SQLFeatureNotSupportedException - the JDBC driver does not support this method

      public void setTime​(int parameterIndex, Time x, Calendar cal) throws SQLException
      Sets the designated parameter to the given java.sql.Time value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIME value, which the driver then sends to the database. With a Calendar object, the driver can calculate the time taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.

      Sets the designated parameter to the given java.sql.Timestamp value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIMESTAMP value, which the driver then sends to the database. With a Calendar object, the driver can calculate the timestamp taking into account a custom timezone. If no Calendar object is specified, the driver uses the default timezone, which is that of the virtual machine running the application.
      Specified by:
      setTimestamp in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      x - the parameter value
      cal - the Calendar object the driver will use to construct the timestamp

    • setUnicodeStream

      @Deprecated public void setUnicodeStream​(int parameterIndex, InputStream x, int length) throws SQLException
      Deprecated.
      Sets the designated parameter to the given input stream, which will have the specified number of bytes. A Unicode character has two bytes, with the first byte being the high byte, and the second being the low byte. When a very large Unicode value is input to a LONGVARCHAR parameter, it may be more practical to send it via a java.io.InputStream object. The data will be read from the stream as needed until end-of-file is reached. The JDBC driver will do any necessary conversion from Unicode to the database char format. Note: This stream object can either be a standard Java stream object or your own subclass that implements the standard interface.
      Specified by:
      setUnicodeStream in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      x - a java.io.InputStream object that contains the Unicode parameter value as two-byte Unicode characters
      length - the number of bytes in the stream
      Throws:
      SQLException - if a database access error occurs
      SQLFeatureNotSupportedException - the JDBC driver does not support this method

    • setURL

      public void setURL​(int parameterIndex, URL x) throws SQLException
      Sets the designated parameter to the given java.net.URL value. The driver converts this to an SQL DATALINK value when it sends it to the database.
      Specified by:
      setURL in interface PreparedStatement
      Parameters:
      parameterIndex - the first parameter is 1, the second is 2, ...
      x - the java.net.URL object to be set
      Throws:
      SQLException - if a database access error occurs

    • close

      public void close()
      Releases this PreparedStatement object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed. It is generally good practice to release resources as soon as you are finished with them to avoid tying up database resources. Calling the method close on a PreparedStatement object that is already closed has no effect. Note: A PreparedStatement object is automatically closed when it is garbage collected. When a Statement object is closed, its current ResultSet object, if one exists, is also closed.
      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface Statement
      Overrides:
      close in class MonetStatement

    • finalize

      protected void finalize()
      Call close to release the server-sided handle for this PreparedStatement.
      Overrides:
      finalize in class Object
