Question

I was provided with an SQL query that outputs (PRINT) data neatly, the sticky part is that I need to execute it (and use the output later obviously) through my application which already makes use of EF4.1.

Here’s what I have so far.

        string sqlQuery = string.Empty;
        _ctx.Connection.Open();
        DbCommand com = _ctx.Connection.CreateCommand();

        sqlQuery = @"declare @note varchar(1000)
                    set @note = (select
                    'Client: '+cast([NO_CLIENT] as varchar)+' - '+TABLE1.[nom]+
                    CHAR(13)+CHAR(10)+
                    'Adr_1 '+[ADR_1]+

                        where [NO_CLIENT] = 2003)


                    print @note

                ";

        com.CommandText = @sqlQuery;
        DbDataReader rd = com.ExecuteReader();

The query executes fine in SQL Management Studio, but I get this exception when the application runs it: (looks like it is parsing it somehow)

The query syntax is not valid. Near term '@note', line 1, column 14.

What do you think am I doing wrong ? (Probably everything lol)

Answer 1

Here’s what I ended up doing:

var r = _ctx.ExecuteStoreQuery<string>(@sqlQuery).FirstOrDefault();

The sqlQuery declares and sets value for @note, then select‘s it in the end.

r will contain flat text.

This has pointed me in the right direction: ExecuteStoreCommand returns -1 , EntityFramework , C#?
