Question

I am using Entity Framework ExecuteStoreQuery to call a MySql stored procedure with output parameter. The store procedure also returns a result set.

I get the following error.

OUT or INOUT argument 2 for routine mydb.mysp is not a variable or NEW pseudo-variable in BEFORE trigger

What is wrong? Is there a better way to call MySql sp with mix of out params and resultset?

Here is the code

     var outParam = new MySqlParameter();
                outParam.ParameterName = "totalRowsOut";
                outParam.MySqlDbType = MySqlDbType.Int64;
                outParam.Direction = ParameterDirection.Output;

var data =  db.ExecuteStoreQuery<PropertySearchResultRow>
(
    "call mysp(@input1, @totalRowsOut);", 
    new MySqlParameter("input1", 10),
    outParam
);

var result = data.ToList();
int totalRowsCount = (int)outParam.Value;

Answer 1

Finally ended up using the ado.net MySqlCommand to call the stored proc and get the out value. Mysql and EF integration is bad.
