Change the execution mode for the specified function from unprotected mode to protected mode. For details, see the ALTER FUNCTION topic "When to Specify Unprotected Mode" in Teradata Vantage™ SQL Data Definition Language Detailed Topics , B035-1184 .
- Change the execution mode for the specified function from protected mode to unprotected mode.
- This option is not valid for Java UDFs.
Example: Setting the Protection Mode of a UDF to EXECUTE NOT PROTECTED
ALTER FUNCTION TransXML EXECUTE NOT PROTECTED;
Example: Setting a Recompiled UDF to EXECUTE NOT PROTECTED
An existing UDF named XPathValue must be recompiled for some reason. XPathValue had previously been set to run in unprotected mode. Recompiling a UDF always resets its protection mode back to protected, so you must follow any recompilation with another ALTER FUNCTION request to set its protection mode back to unprotected.
ALTER FUNCTION XPathValue COMPILE; ALTER FUNCTION XPathValue EXECUTE NOT PROTECTED;
