Shouldn't matter. How are you calling the program? From a CL, RPG, RPGLE,
SQL Stored Procedure?

I am clearing the field as soon as the control comes into the program.

And

i have checked the field value in debug and it appears as blanks too.

Does

it makes any difference clearing the field immedialy before fetch and
clearing it when control comes in? As i am not in front of pc now i

cannot

try now.

You need to clear the field you are fetching into before you do the

fetch.

A fetch with an SQLCOD of 100 does not change the contents that

currently

exist in the field(s). Just like the Chain when not found doesn't

change

it's field values nor the read when at end of file.

pseudo

Declare cursor using statement
Prepare statement
Open cursor
clear field
fetch cursor into field
close cursor
return field


Sometimes, I will close the cursor before opening... just to make sure

that

it was closed. Otherwise you'll get the previous results.

Betreff: Strange issue in embedded sql

I have a program which accepts the Sql statements user enters and

these

statements are passed onto a sqlrpgle program which declare a

scroll

cursor
and prepares the sql from the string which holds input parameter.

It

then

issues a fetch first statement into a field which will hold the

query

reasult. I am checking sql code to determine whether the entered

query

is

valid or not. I close the cursors after this. If first time i

entered

a

valid sql i get the result..for second time if some irrelevant

data

is

entered still the fetch statement returns previous sql's output

and

sqlcod

also is zero as if i entered correct sql. Pls help me to figure

out

the

problem here....
