Question

I want to do an insert and an update on 2 separate tables, but have them be in 1 transaction).

Essentially in pseudocode I want to do something like:

MySqlTransaction trans = null; try {     _Connection.Open();     trans = _Connection.BeginTransaction();     insertCmd.Transaction = trans;     updateCmd.Transaction = trans;      Int32 id = insertCmd.ExecuteNonQuery();     updateCmd.Parameters.Add(new MySqlParameter('oid', MySqlDbType.Int32).Value = id);     updateCmd.ExecuteNonQuery(); } catch(MySqlException) {     if(trans != null)         trans.RollBack(); } finally {     _Connection.Close(); } 

is this possible or am I going about this the wrong way?

Answer 1

Yes you can if:

• All the tables support it, (InnoDB tables support it, but MyIsam tables don’t)
• The queries don’t affect the database-schema. (ALTER TABLE, DROP TABLE, CREATE TABLE, etc causes the transaction to commit)
