Hello,

I'm currenty trying to update an interface from an Oracle Forms app to a view on a 10G database. When I query the view to check if the user is a valid user of the interfacing database/application it returns a ORA-01422 Error.

Here is my query in Forms:

select userid into string from recharge_link_user.maxuser
where userid = upper(userid);


When I execute this (modified)query in Toad, against the same view, it returns ONE row.

select userid from recharge_link_user.maxuser
where userid = upper('admin');


I have even retrieved all rows in the view and verified there is only one entry for 'admin' by sorting.

It seems as though Oracle is throwing this error for a few different queries and not just this one. Is this an issue between the version of Forms and 10G? Am I missing something here?

Thanks

select userid into string from recharge_link_user.maxuser
where userid = upper(userid);

select userid from recharge_link_user.maxuser
where userid = upper('admin');

Both queries may be run in pure SQL; however they return different result:
The first one returns all rows, where USERID column does not contain lower case letter.
The second one returns all rows, where USERID column contain value 'ADMIN'.

You may have a variable named USERID in Forms; however it will not be used in this query. The only way to use a variable in query is renaming it. The good coding convention is adding a prefix to a variable name, which identifies its scope (e.g. L_ for local variables, P_ for parameters etc.). You may use any other naming convention though.
