Unfortunately it does not work and returns only 0, while my custom query using LAST_INSERT_ID() works as expected.
Debugging this is very hard as Lazarus crashes on me left and right when trying to step through the code and an exception is encountered.
I have one connection, one transaction and some queries bound to them on a FPWebModule.

ID1:=MySQL55Connection1.GetInsertID;
SQLQuery1.Open;
ID2:=SQLQuery1.FieldByName('LastInsertID').AsLargeInt;

ID1 is 0 and ID2 the correct id value.

Any ideas what I could be doing wrong?
