Cobol is probably the oldest language used for SQL.
Well over 20 years on VMS and earlier on IBM mainframes.

You have absolutely no idea what you are talkning about. Is this also
true for your other posts where I can't see it just as easy?

You do not need any string handling at all to run SQL databases from Cobol.

Besides, is there any serious environment at all where you build SQL
statements using string manipulation? Of course not! That is a trap
to get into SQL injections just waiting to happen.

You probably haven't done much real database programming...

Based on the above rubbish? Right... :-)
