Fmtonly ON when calling SP - mssql

[Clarion_clarion]

Hi all,

MSSQL driver

I have starge problem, I am calling SP from Clarion as usual using prop:sql

mytable{:prop:sql} = 'Call MySP'

usually Clarion SQL driver convert it to and executed in sql as

exec MySP

and it works fine.

But sometime it generate something like this:

SET FMTONLY On EXEC MySP SET FMTONLY OFF

so somehow it adds SET FMTONLY before and after EXEC (in one line) and prop:sql returns error 90.

Why?? Who are triggering SET FMTONLY ??

my Sp defined as this:

CREATE PROCEDURE mySP (	
	--@ReturnCode smallint output
) AS
BEGIN
	Declare
	@ReturnCode smallint
	
	set @ReturnCode = -1
		
	select @ReturnCode
	
END

so it returns some value using SELECT and we can read it by
NEXT(mytable)

best regards,
Guennadi

mytable{sql:prop} = ‘Call MySP’

Hi,
is it mytable{PROP:SQL} = ‘Call MySP’ ?

[Clarion_clarion]

sure!!! otherwise I will have compile error…
will edit original post

Have you tried
MyTable{Prop:SQL} = 'CALL MySP()'
Just a guess.

Rick,
As I mentioned it works fine!!! So syntax not a problem. Problem is that somehow / sometime it generates
SET FMTONLY On EXEC MySP SET FMTONLY OFF

instead of just
EXEC MySP

I had this situation today but it was nothing to do with a stored procedure.
Do you ever deal with different databases within the same application? In my case I think it was related to switching the db owner at a not cool point. The driver was not happy and threw an error “object not found” type of error back. Looking at the sql profiler I saw the exact same FMTONLY thing just after it attempted my SELECT statement.
I fixed the code to not switch the db owner and everyone is happy again.

It is always the same table and the connection!!

I have checked different scenarios and realized that Clarion (?? Or sql) generate this surrounding statements only if slq object doesn’t exist . So in my case somehow MySP stored procedure looks like doesn’t exist.

I am looking for the reason why… Because logic in the clarion code is very difficult and probably we have some issue like closing tables or disconnection etc…

So in my case somehow MySP stored procedure looks like doesn’t exist.

Maybe the reason it seems to not exist is a permissions issue.
Also, what DataType is the first field in the table MyTable ? Is it numeric so that no CW type conversion is happening as you are returning -1

mytable{:prop:sql} = ‘Call MySP’

What is the definition of myTable ?
In my case I was using s non-threaded variable for the Driver/Owner string. Changing these to be threaded, as per the documentation, caused my problem to go away.
