Hello Diapason!
Indeed, "UpdateTable" dont have "transaction" support [I will try improve it!]
but, yes, ExecSQL, have ["under the hat"] "transaction" support !!!!
[Ok. We can improve here, too, returning true or false .... I will try improve it!]
The java [called ] code is "jSqliteDataAccess.java" [ LAMW folder " .....\java\lamwdesigner"]
