c# - MySql Last Insert ID, Connector .net

Question

I'm using the MySql Connector .net, and I need to get the insert id generated by the last query. Now, I assume the return value of MySqlHelper.ExecuteNonQuery should be the last insert id, but it just returns 1.

The code I'm using is:

int insertID = MySqlHelper.ExecuteNonQuery(Global.ConnectionString, 
"INSERT INTO test SET var = @var", paramArray);

However insertID is always 1. I tried creating a MySql connection and opening/closing manually which resulted in the same behaviour

Answer 1

Just use LastInsertedId field

MySqlCommand dbcmd = _conn.CreateCommand();
dbcmd.CommandText = sqlCommandString;
dbcmd.ExecuteNonQuery();
long imageId = dbcmd.LastInsertedId;
