Method Detail

executeScript

public static void executeScript(Connection conn,
                                 String file,
                                 String charset)

checkIfTableExists

public static boolean checkIfTableExists(Connection conn,
                                         String tableName)

close

public static void close(Statement stmt)

close

public static void close(ResultSet rset,
                         Statement stmt)

close

public static void close(Statement stmt,
                         Connection conn)

close

public static void close(ResultSet rset,
                         Statement stmt,
                         Connection conn)

fillStatement

public static int fillStatement(PreparedStatement stmt,
                                Object... params)

Fill the given PreparedStatement object with the specified parameters.

Note that this method uses the setObject method which depends of a specified JDBC driver implementation to work properly.

Parameters:

stmt - - The PreparedStatement object

params - - Values that will be added in statement

Returns:

The last index added plus 1. It can be useful for continuous statement filling operations.

fillStatementIndx(PreparedStatement, int, Object...), PreparedStatement.setObject(int, Object)

fillStatementIndx

public static int fillStatementIndx(PreparedStatement stmt,
                                    int indx,
                                    Object... params)

Fill the given PreparedStatement object with the specified parameters starting at indx position.

Note that this method uses the setObject method which depends of a specified JDBC driver implementation to work properly.

Parameters:

stmt - - The PreparedStatement object

indx - - Initial index for setting attributes in statement

params - - Values that will be added in statement

Returns:

The next index (last added plus 1). It can be useful for continuous statement filling operations.

                                 throws SQLException

Prepare a statement (PreparedStatement) with the query and set the parameters.

Parameters:

conn - the connection

query - the query to prepare

params - the parameters to set in the query

Returns:

the statement ready to be executed

Throws:

SQLException
