The embedded sql pre-processor by Oracle is called Pro*C and NOT Proc*C.
Thus, it is just plain wrong to introduce proc-c as new tag for Pro*C.
Unfortunately, the proc-c tag was already created - but no questions are tagged with it. It should be removed for the stated reasons.
Currently, there are 49 questions tagged with proc-sql and oracle.
On the other hand there are 45 questions tagged with proc-sql and sas.
Thus, the proc-sql tag is NOT exclusively used for SAS questions.
Looking at the revision history of the tag proc-sql the description is only about SAS usage - but when browsing the tag wiki, the old Oracle Pro*C info is displayed. Probably because of suggested edits.
A better alternative to resolve the proc-sql mess:
- introduce a new tag pro-c for Oracle Pro*C related questions (proc is already used for a Ruby construct of the same name, but pro-c is currently not in use)
Anyway, when doing such changes, the one doing them should also be responsible for migrating all the old Pro*C questions!
