Hello SQL Team!
I'm stuck at this problem for days and need help.
The problem is with the GO keyword. I know the GO causes the batch to get executed and all local variables are lost. But I can't seem to find a work around. I would like each stored procedure to get executed in different batches.

create table sql_cmd(cmd nvarchar(255))
insert into sql_cmd(cmd) values('exec user_sp param1,''param2'')
insert into sql_cmd(cmd) values('exec user_sp2 param1,''param2'')

declare @sql nvarchar(255)
declare c_sql cursor --small table peformance not a problem. Also open to other suggestions
for select cmd from sqlcmd
open c_sql
fetch next from c_sql
into @sql
while @@fetch_status = 0
begin
print @sql
exec sp_executesql @sql
GO
fetch next from c_sql
into @sql
end

Remove the GO and you should be good. Dynamic SQL executes in its own batch already, so GO isn't needed to start a new one.

"Dynamic SQL executes in its own batch already"

I did not know that. Thank you. Is there any documentation on that?

I'm sure there is, but I don't have it handy.
