D UcFirst pr 512 varying
D pString 512 value varying
I tried to define a SQL Procedure as such:
CREATE FUNCTION UCFIRST (
INSTR VARCHAR(512))
RETURNS VARCHAR(512)
LANGUAGE RPGLE
PARAMETER STYLE GENERAL...
I could call the procedure but it crashed with an 'index out of bounds'
error. When I debugged, I saw garbage in the parameter. So, I changed the
prototype/interface to:
D UcFirst pr 512 varying
D pString 512 const varying
Note the keyword CONST instead of VALUE. Everything worked.
Can you not call RPGLE procedures from SQL if the procedure expects values
passed by value? Just wondering if there is another way to solve this
without always changing the procedure definition. Also, is there a
document that discusses passing of parameters between RPG and SQL, because
I cannot find one. I am sure I am just missing it.
