잘못된 SQL 구문 오류 ADO.NET

Question

실행하려고하면 SqlException 메시지가 "잘못된 구문을 'PROCEDURE'키워드 근처에 가져옵니다."

120: cmd.CommandText = @"CREATE PROCEDURE FindState @Name nvarchar(50) 
    AS SELECT IDState FROM State WHERE Name=@Name"; 
121: cmd.ExecuteNonQuery();

그러나 나는 SQL 쿼리에서 직접 SQL 명령을 복사하고 실행을 시도하고 일했다.

SqlParameter stateName = new SqlParameter(); 
stateName.SqlDbType = SqlDbType.NVarChar; 
stateName.Direction = ParameterDirection.Input; 
stateName.ParameterName = "@Name"; 
stateName.Size = 50; 
Console.Write("Enter state name: "); 
stateName.Value = Console.ReadLine(); 
cmd.Parameters.Add(stateName); 

cmd.CommandText = "IF EXISTS (SELECT name FROM sysobjects WHERE name='FindState' AND type='P') DROP PROCEDURE FindState"; 
cmd.ExecuteNonQuery(); 
cmd.CommandText = "CREATE PROCEDURE FindState 
@Name nvarchar(50) 
AS 
BEGIN 
SELECT IDState FROM State WHERE Name=@Name"; 
END 

cmd.CommandType = CommandType.StoredProcedure; 
cmd.ExecuteNonQuery(); 
cmd.CommandText = "FindState"; 

sdr = cmd.ExecuteReader(); 
if (sdr.HasRows) 
{ 
    while (sdr.Read()) 
    { 
    Console.WriteLine("ID state " + stateName.Value + " is " + sdr[0]); 
    } 
} 
else 
{ 
    Console.WriteLine("No such state exists"); 
} 
sdr.Close(); 

Answer 1

나는 문제가 무엇인지 파악 :

이 시도 여기에 몇 가지 문맥을주는 코드

SqlParameter stateName = new SqlParameter(); 
stateName.SqlDbType = SqlDbType.NVarChar; 
stateName.Direction = ParameterDirection.Input; 
stateName.ParameterName = "@Name"; 
stateName.Size = 50; 
Console.Write("Enter state name: "); 
stateName.Value = Console.ReadLine(); 
cmd.Parameters.Add(stateName); 

cmd.CommandText = @"IF EXISTS (SELECT name FROM sysobjects WHERE name='FindState' AND type='P') DROP PROCEDURE FindState"; 
cmd.ExecuteNonQuery(); 
cmd.CommandText = @"CREATE PROCEDURE FindState 
@Name nvarchar(50) 
AS 
SELECT IDState FROM State WHERE Name=@Name"; 
cmd.ExecuteNonQuery(); 
cmd.CommandType = CommandType.StoredProcedure; 
cmd.CommandText = "FindState"; 
sdr = cmd.ExecuteReader(); 
if (sdr.HasRows) 
{ 
    while (sdr.Read()) 
    { 
    Console.WriteLine("ID state " + stateName.Value + " is " + sdr[0]); 
    } 
} 
else 
{ 
    Console.WriteLine("No such state exists"); 
} 
sdr.Close();

조금 더 큰 섹션하기 위해 (이 절차를 생성). 매개 변수가 프로 시저를 만들기 전에 SqlCommand에 추가되었습니다. 투표를 닫 없습니다 - 매개 변수를 정리하지 않습니다에는 행 번호와 코드가 나는 아래 줄을 이동 지금은 (스택 추적과)

cmd.CommandText = @"CREATE PROCEDURE FindState @Name nvarchar(50) AS SELECT IDState FROM State WHERE Name=@Name"; 
cmd.ExecuteNonQuery(); 
cmd.CommandType = CommandType.StoredProcedure; 
cmd.CommandText = "FindState"; 
cmd.Parameters.Add(stateName); 
sdr = cmd.ExecuteReader();
