#RIP #Dudley #GDML in Firebird 3.0 – #Sql won

Dudley – Sounds like DDL (data definition language) and is the pre (interbase) 4.0 data definition utility GDEF. It’s actually named after Dudley Doright, a character from Rocky and Bullwinkle. GDEF accepts a data definition language based on GDML.

DDL utility. Interpreted commands in the old data definition language (declare relation, declare field – square brackets where you want to put parentheses). Generates BLR for views and triggers, GDML (non-SQL relational language) for metadata updates.
