The sql query object and transaction object are created but not freed: http://www.freepascal.org/docs-html/fcl/sqldb/usingsqldb.html I think the docs should mention that the objects need not to be freed, as this violates normal programming practice of freeing all objects you create.
They must of course be freed. They ARE freed.
P.s. how is it freed magically? Sorry I am on cell phone and cannot look at source easily to find out
All three classes are components. Q and T are owned by C. When C is freed, Q and T are freed.
This is one gripe I have with programming is that you never really know if something should be freed just by looking at the code. If it is not freed and it was created by you it is a good indication its a mem leak, but not if there is magic behind the scenes to free it automatically
There is no magic other than standard TComponent owner/owned functionality. Michael. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
