I want to execute commands like
exec sp_who2 via IDataAbstractService.SQLGetData
However when I do that I get the exception below
An exception occurred on the server: A SchemaField called "SPID" has already been added to the collection SchemaFieldCollection
How can this be solved?
Note: For some reason the sp_who2 command returns 2 columns with the name SPID
Hi,
can you share DDL for creating this stored procedure, pls?
it can be DDL with empty body.
It is a stored procedure that is provided by microsoft. It is part of MS SQL

Hi,
this is non-standard case when stored procedure contains 2 fields with the same name.
you can try to do workaround with select from exec as described at sql - How to SELECT FROM stored procedure - Stack Overflow
EDIT:
use SQL like:
exec sp_who2 WITH RESULT SETS
(
(
SPID char(5),
Status varchar(50),
Login varchar(50),
HostName varchar(50),
BlkBy char(5),
DBName varchar(50),
Command varchar(50),
CPUTime varchar(50),
DiskIO varchar(50),
LastBatch varchar(50),
ProgramName varchar(50),
SPID1 char(5),
REQUESTID char(5)
)
)
A bit inconvenient but it will do,
Thanks!
