Re: DROP FUNCTION

Sometime ago I created an SQL UDF twice, with different parameters.
When I query the SYSFUNCS table, I can see it registered twice with
different signatures, once with 2 parameters and again with 3
parameters.

I wanted to DROP /both/ functions, but I could not remember how I
created the one that takes 3 parameters.

By using System i Navigator and expanding
Database->DbName->Schema->Libname->Functions, I was able to
right-click on each of the functions and deleted them.

Here is my question: How would I use the green-screen SQL interpreter
(STRSQL) to drop a UDF, not knowing how it was created?


Query the SYSFUNCS VIEW and get the SPECNAME to either use that SPECIFIC_NAME value in the SQL request DROP SPECIFIC FUNCTION specific-function-name or to use that SPECIFIC_NAME value to query either SYSPARMS or PARAMETERS to then build the SQL request to: DROP FUNCTION function-name ( parameter-type-list )
