throws java.sql.SQLException
Statement object for sending
SQL statements to the database.
SQL statements without parameters are normally
executed using Statement objects. If the same SQL statement
is executed many times, it is more efficient to use a
PreparedStatement object.
Result sets created using the returned Statement
object will by default have forward-only type and read-only concurrency.
createStatement in interface java.sql.Connectionjava.sql.SQLException - if a database access error occurspublic java.sql.PreparedStatement prepareStatement(java.lang.String sql)
throws java.sql.SQLException
PreparedStatement object for sending
parameterized SQL statements to the database.
A SQL statement with or without IN parameters can be
pre-compiled and stored in a PreparedStatement object. This
object can then be used to efficiently execute this statement
multiple times.
Note: This method is optimized for handling
parametric SQL statements that benefit from precompilation. If
the driver supports precompilation,
the method prepareStatement will send
the statement to the database for precompilation. Some drivers
may not support precompilation. In this case, the statement may
not be sent to the database until the PreparedStatement is
executed. This has no direct effect on users; however, it does
affect which method throws certain SQLExceptions.
Result sets created using the returned PreparedStatement will have
forward-only type and read-only concurrency, by default.

throws java.sql.SQLException
CallableStatement object for calling
database stored procedures.
The CallableStatement object provides
methods for setting up its IN and OUT parameters, and
methods for executing the call to a stored procedure.
Note: This method is optimized for handling stored
procedure call statements. Some drivers may send the call
statement to the database when the method prepareCall
is done; others
may wait until the CallableStatement object
is executed. This has no
direct effect on users; however, it does affect which method
throws certain SQLExceptions.
Result sets created using the returned CallableStatement will have
forward-only type and read-only concurrency, by default.

commit or the method rollback.
By default, new connections are in auto-commit
mode.
The commit occurs when the statement completes or the next
execute occurs, whichever comes first. In the case of
statements returning a ResultSet, the statement completes when
the last row of the ResultSet has been retrieved or the
ResultSet has been closed. In advanced cases, a single
statement may return multiple results as well as output
parameter values. In these cases the commit occurs when all results and
output parameter values have been retrieved.setAutoCommit in interface java.sql.ConnectionautoCommit - true enables auto-commit; false disables

For dialect 2 and 3, the name is restricted to the rules for Firebird quoted identifiers (essentially any printable character and space is valid), and the name is handled case sensitive.
