How to use DbContext.Database.SqlQuery(sql, params) with stored procedure? EF Code First CTP5

Question

I have a stored procedure that has three parameters and I\'ve been trying to use the following to return the results:

context.Database.SqlQuery

        

Answer 1

This solution is (only) for SQL Server 2005

You guys are lifesavers, but as @Dan Mork said, you need to add EXEC to the mix. What was tripping me up was:

• 'EXEC ' before the Proc Name
• Commas in between Params
• Chopping off '@' on the Param Definitions (not sure that bit is required though).

:

context.Database.SqlQuery<EntityType>(
    "EXEC ProcName @param1, @param2", 
    new SqlParameter("param1", param1), 
    new SqlParameter("param2", param2)
);

Answer 2

You should supply the SqlParameter instances in the following way:

context.Database.SqlQuery<myEntityType>(
    "mySpName @param1, @param2, @param3",
    new SqlParameter("param1", param1),
    new SqlParameter("param2", param2),
    new SqlParameter("param3", param3)
);

Answer 3

db.Database.SqlQuery<myEntityType>("exec GetNewSeqOfFoodServing @p0,@p1,@p2 ", foods_WEIGHT.NDB_No, HLP.CuntryID, HLP.ClientID).Single()

or

db.Database.SqlQuery<myEntityType>(
    "exec GetNewSeqOfFoodServing @param1, @param2", 
    new SqlParameter("param1", param1), 
    new SqlParameter("param2", param2)
);

or

var cmdText = "exec [DoStuff] @Name = @name_param, @Age = @age_param";
var @params = new[]{
   new SqlParameter("name_param", "Josh"),
   new SqlParameter("age_param", 45)
};

db.Database.SqlQuery<myEntityType>(cmdText, @params)

or

db.Database.SqlQuery<myEntityType>("mySpName {0}, {1}, {2}",
new object[] { param1, param2, param3 }).ToList();

Answer 4

I use this method:

var results = this.Database.SqlQuery<yourEntity>("EXEC [ent].[GetNextExportJob] {0}", ProcessorID);

I like it because I just drop in Guids and Datetimes and SqlQuery performs all the formatting for me.
