I had an existing WebI 6.1a report which had been working fine.
Now I am getting an error:
Database error: ORA-00932: inconsistent datatypes: expected %s got %s . Contact your administrator or database supplier for more information. (Error: WIS 10901)
Are you able to see the SQL? If so, show it to your DBA and have them see if they can spot an error. Since you’re getting an Oracle error, it must be something in the SQL that Oracle doesn’t like. Feel free to post the SQL here, as well.
