Notes on the Saxon implementation
Introduced in Saxon 9.9. Designed to supersede the extension instruction sql:execute. The saxon9-sql.jar
file,
distributed alongside the main JAR file, must be added to the classpath when these SQL extension functions
are used.
Details
The function executes a SQL statement, and returns no result.
If the statement is COMMIT WORK
or ROLLBACK WORK
(exactly as written)
then it is intercepted and translated into a call on $connection?commit()
or $connection?rollback_0()
.
Although the declared return type is item()?
, the function always returns an empty
sequence. The declared return type is designed to prevent the optimizer making unwarranted assumptions.
Because this function is executed for its side-effects, it is recommended to invoke it using the saxon:do extension instruction.
Example:
<saxon:do action="sql:execute($connection, 'DROP TABLE book')"/>
