execute

public void execute(PreparedStatementFactory factory)
             throws DatabaseException

Description copied from interface: ExecutablePreparedStatement

Executes the prepared statement created by the given factory.

Specified by:

execute in interface ExecutablePreparedStatement

Parameters:

factory - a factory for creating a PreparedStatement object.

Throws:

DatabaseException - if an exception occurs while executing the prepared statement.

protected void executePreparedStatement(PreparedStatement stmt)
                                 throws SQLException

Throws:

SQLException

attachParams

protected void attachParams(List<? extends ColumnConfig> cols,

                            DatabaseException

Sets the list of bind variables for the execution of a DML statement

Parameters:

cols - a list of columns with their designated values

stmt - the PreparedStatement to which the values are to be attached

Throws:

SQLException - if JDBC objects to a setting (non-existent bind number, wrong column type etc.)

                                    DatabaseException

Sets a single bind variable for a statement to its designated value

Parameters:

stmt - the PreparedStatement whose parameter is to be set

i - the parameter index (first bind variable is 1)

col - a ColumnConfig with information about the column, its type, and the desired value

Throws:

SQLException - if JDBC objects to a setting (non-existent bind number, wrong column type etc.)
