public class FBStatement extends java.lang.Object implements FirebirdStatement, Synchronizable
Only one ResultSet object per Statement object
can be open at any point in
time. Therefore, if the reading of one ResultSet object is interleaved
with the reading of another, each must have been generated by
different Statement objects. All statement execute
methods implicitly close a statement's current ResultSet object
if an open one exists.

In some (uncommon) situations, a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string.
The execute method executes an SQL statement and indicates the
form of the first result. You must then use the methods
getResultSet or getUpdateCount
to retrieve the result, and getMoreResults to
move to any subsequent result(s).

It is generally good practice to release resources as soon as

Calling the method close on a Statement
object that is already closed has no effect.
Note: A Statement object is automatically closed when it is
garbage collected. When a Statement object is closed, its current

method is a noop. To insure that a cursor has the proper isolation
level to support updates, the cursor's SELECT statement should be
of the form 'select for update ...'. If the 'for update' phrase is
omitted, positioned updates may fail.
Note: By definition, positioned update/delete
execution must be done by a different Statement object than the one
which generated the ResultSet object being used for positioning. Also,
cursor names must be unique within a connection.

int elements of the array that is returned are ordered

according to the order in which they were added to the batch.
The elements in the array returned by the method executeBatch
may be one of the following:
-2 -- indicates that the command was
processed successfully but that the number of rows affected is
unknown
If one of the commands in a batch update fails to execute properly,
this method throws a BatchUpdateException, and a JDBC
driver may or may not continue to process the remaining commands in
the batch. However, the driver's behavior must be consistent with a
particular DBMS, either always continuing to process commands or never
continuing to process commands. If the driver continues processing
after a failure, the array returned by the method
BatchUpdateException.getUpdateCounts
will contain as many elements as there are commands in the batch, and
at least one of the elements will be the following:
-3 -- indicates that the command failed
to execute successfully and occurs only if a driver continues to
process commands after a command fails
A driver is not required to implement this method.
The possible implementations and return values have been modified in
the Java 2 SDK, Standard Edition, version 1.3 to
accommodate the option of continuing to proccess commands in a batch
update after a BatchUpdateException obejct has been thrown.

FirebirdStatementNOTE: This method is only included in this interface to try and avoid problems with proxied and bytecode enhanced classes in certain libraries, you should normally have no reason to call this method directly.
The id is expected - but not guaranteed - to be unique for a single connection, and - preferably - for the entire JVM run time as well.
