存儲過程

Question

我有一個創建一個用戶配置文件的存儲過程，我的形式有以下字段：

FirstName, 
LastName. 
EmailAddress, 
ZipCode, 
Password 

的郵政編碼是一個FK在我喜歡的類型的用戶配置SMALLINT值可能會或可能不會已經在表格中存在名爲Location：

LocationId bigInt (identity index) 
ZipCode smallint 

有沒有從我的存儲過程中的方式來查詢該表，如果該項目存在使用了PK在我的存儲過程中輸入？

這也是迄今爲止

CREATE PROCEDURE [dbo].[SP_InsertInitialProfile] 

@FirstName   NVARCHAR(1000), 
@LastName   NVARCHAR(1000), 
@EmailAddress  NVARCHAR(1000), 
@ZipCode   SMALLINT, 
@Password   NVARCHAR(1000) 

AS 

IF (SELECT COUNT(1) FROM UserProfile WHERE EmailAddress =@EmailAddress) = 1 
BEGIN 
    RETURN -1 
END ELSE 
BEGIN 
    INSERT INTO UserProfile(FirstName,LastName,EmailAddress,Password) 
    VALUES(@FirstName,@LastName,@EmailAddress,@Password) 

    RETURN Cast(@@IDENTITY as INT) 
END

你可以做SP像這樣我的存儲過程：

  CREATE PROCEDURE [dbo].[SP_InsertInitialProfile] 

      @FirstName   NVARCHAR(1000), 
      @LastName   NVARCHAR(1000), 
      @EmailAddress  NVARCHAR(1000), 
      @ZipCode   SMALLINT, 
      @Password   NVARCHAR(1000) 

      AS 

      varCountNbr number; 

      BEGIN 

       SELECT COUNT(1) INTO varCountNbr 
       FROM 
        Location 
       WHERE 
       ZipCode=@ZipCode; 

       IF varCountNbr = 0 
        INSERT @ZipCode INTO Location TABLE; 
       -- You have to commit here, in order to have the PK value exists. 
        COMMIT; 

       INSERT INTO USERPROFILE TABLE; 

       COMMIT; 


      END;
