I have the following error in my pro-c program.
(ORA-01423: error encountered while checking for extra rows in exact rows in exact fetch in "select no into :b0 from num@aaa"
num table has and will alway have 1 row of data only.
The thing is that this error occurs at abnormal times. At times, it is okay and at other times, the error occurs.
What could be the problem? This seems to happen after I added the dblink. Could this affect it?
