  • Method Details

    • getParameterCount

      public int getParameterCount() throws SQLException
      Retrieves the number of parameters in the PreparedStatement object for which this ParameterMetaData object contains information.
      Specified by:
      getParameterCount in interface ParameterMetaData
      Returns:
      the number of parameters
      Throws:
      SQLException

    • isNullable

      public int isNullable​(int param) throws SQLException
      Retrieves whether null values are allowed in the designated parameter. Currently not supported.
      Specified by:
      isNullable in interface ParameterMetaData
      Parameters:
      param - Parameter number (starts at 1)
      Returns:
      the nullability status of the given parameter; one of ParameterMetaData.parameterNoNulls, ParameterMetaData.parameterNullable, or ParameterMetaData.parameterNullableUnknown
      Throws:
      SQLException

    • isSigned

      public boolean isSigned​(int param) throws SQLException
      Retrieves whether values for the designated parameter can be signed numbers.

      getPrecision in interface ParameterMetaData
      Parameters:
      param - Parameter number (starts at 1)
      Returns:
      precision
      Throws:
      SQLException

    • getScale

      public int getScale​(int param) throws SQLException
      Retrieves the designated parameter's number of digits to right of the decimal point. Currently not supported.
      Specified by:
      getScale in interface ParameterMetaData
      Parameters:
      param - Parameter number (starts at 1)
      Returns:
      scale
      Throws:
      SQLException

    • getParameterType

      public int getParameterType​(int param) throws SQLException
      Retrieves the designated parameter's SQL type.
      Specified by:
      getParameterType in interface ParameterMetaData
      Parameters:
      param - Parameter number (starts at 1)
      Returns:
      SQL type from java.sql.Types
      Throws:
      SQLException - if the column parameter is out of bounds

    • getParameterTypeName

      public String getParameterTypeName​(int param) throws SQLException
      Retrieves the designated parameter's MonetDBe type name as a String.
      Specified by:
      getParameterTypeName in interface ParameterMetaData
      Parameters:
      param - Parameter number (starts at 1)
      Returns:
      MonetDBe type
      Throws:
      SQLException - if the column parameter is out of bounds

    • getParameterClassName

      public String getParameterClassName​(int param) throws SQLException
      Returns the fully-qualified name of the Java class whose instances are manufactured if the method ResultSet.getObject is called to retrieve a value from the column.
      Specified by:
      getParameterClassName in interface ParameterMetaData
      Parameters:
      param - Parameter number (starts at 1)
      Returns:
      the fully-qualified name of the class in the Java programming language that would be used by the method ResultSet.getObject to retrieve the value in the specified column

      SQLException - if the column parameter is out of bounds

    • getParameterMode

      public int getParameterMode​(int param) throws SQLException
      Retrieves the designated parameter's mode. MonetDB doesn't support OUT parameters, so we return ParameterMetaData.parameterModeIn always.
      Specified by:
      getParameterMode in interface ParameterMetaData
      Parameters:
      param - Parameter number (starts at 1)
      Returns:
