Statement Class
Statement Class
A Statement object is used for executing SQL statements. The statement may be a
query returning result set or a non-query statement returning an update count.
Non-query SQL can be insert, update, or delete statements. Non-query SQL
statements can also be DDL statements (such as create, grant, and so on) or stored
procedure calls.
A query, insert / update / delete, or stored procedure call statements may have IN
bind parameters. A DML returning insert / update / delete statement or stored
procedure call may have OUT bind parameters. Finally, a stored procedure call
statement may have bind parameters that are both IN and OUT, referred to as
IN/OUT parameters.
The Statement class methods are divided into three categories:
■ Statement methods applicable to all statements
■ Methods applicable to prepared statements with IN bind parameters
■ Methods applicable to callable statements and DML returning statements with
OUT bind parameters.
To..., use the syntax:

{
UNPREPARED,

RESULT_SET_AVAILABLE,
UPDATE_COUNT_AVAILABLE,
NEEDS_STREAM_DATA,
