execute
- Description
- executes a SQL statement that may return multiple results.
Under 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 navigation through multiple results is covered by
XMultipleResults .
The
execute
method executes a SQL statement and indicates
the form of the first result. You can then use
XStatement::getResultSet()
or
XStatement::getUpdateCount()
to retrieve the result, and
XStatement::getMoreResults()
to move to any subsequent result(s).
- Parameter sql
- any SQL statement
- Returns
- true if the next result is a ResultSet; false if it is an update count or there are no more results
- Throws
- SQLException
if a database access error occurs.

Connection
object
that produced this
Statement
object.
