Hi, Balázs

I don't know whether using temporary tables in FB is discouraged
or not, but I think your problem is the following:
"While a dataset is prepared, it creates an active statement that
lasts until the dataset is unprepared..."
So, you can try:

BEGITRAN
CREATE TABLE TMP_ANY
COMMIT

BEGINTRAN //MySQLConnection.StartTransaction(TD);
INSERT, DELETE, SELECT , etc... on TMP_ANY
COMMIT //MySQLConnection.Commit(TD);
MyDataSet.Prepared := FALSE; // <-- unprepare the dataset

YOU MUST UNPREPARE ALL DATASETS WITH DML COMMANDS (SELECT, UPDATE,
INSERT, DELETE) !!!

Üdvözlet,
Robi
