找不到存储过程

Question

When I try to update my table's data, I'm getting error

Can't find stored procedure

What's wrong?

SQL:

CREATE PROCEDURE GetContactName
   @Name char(20),
   @SecondName char(20) output
as
   SELECT @SecondName = [Second Name] 
   FROM WPF.dbo.contacts 
   WHERE Name = @Name

C#:

sqlConnection.Open();
SqlCommand cmd = new SqlCommand("GetContactName", sqlConnection);
cmd.CommandType = CommandType.StoredProcedure;

SqlParameter param = new SqlParameter();
param.ParameterName = "@Name";
param.SqlDbType = SqlDbType.Char;
param.Direction = ParameterDirection.Input;
cmd.Parameters.Add(param);

param = new SqlParameter();
param.ParameterName = "@SecondName";
param.SqlDbType = SqlDbType.Char;
param.Size = 20;
param.Direction = ParameterDirection.Output;
cmd.Parameters.Add(param);

cmd.ExecuteNonQuery();
sqlConnection.Close();

Edit1

I'm using VS13 and SQL Server 2008 Management Studio.

I can't find stored procedure, but when I'm executing the SQL code, it says that the procedure already exists.

Connection string:

Data Source=HOME;Initial Catalog=WPF;Integrated Security=True

• Database : WPF
• Schema: dbo.contacts

Answer 1

It's a problem of database schema. Check to see if the default schema for the user id used in your connection string matches your SP's schema.

Answer 2

Just add the USE YourdataBaseName follow by GO above your query.

**USE  YourdataBaseName
Go**

CREATE PROCEDURE GetContactName
   @Name char(20),
   @SecondName char(20) output
as
   SELECT @SecondName = [Second Name] 
   FROM WPF.dbo.contacts 
   WHERE Name = @Name
C#:

For some reason, when you create a procedure using sql-query , it is not shown in the folder "Stored Procedures". But if you create a procedure by selecting the appropriate option from the context menu in the "Stored Procedures" folder, it is displayed and everything works.
