Question

我的数据库中有一个UserAcount表。在Profile页面中，用户可以更新其信息。如果Password已填写，我必须更新它，否则我只是更新其他字段。

我这样做，但发生以下错误：

过程或函数'EditUserInfo'需要参数'@Password'，这是未提供的。

ALTER PROCEDURE EditUserInfo
(
    @FirstName NVARCHAR(100),
    @LastName NVARCHAR(200),
    @UserName NVARCHAR(100),
    @Password BINARY
)
AS
BEGIN
    IF (@Password IS NULL)
    BEGIN
        UPDATE UserAcount
        SET FirstName = @FirstName,
            LastName = @LastName
        WHERE UserName = @UserName
    END
    ELSE
    BEGIN
        UPDATE UserAcount
        SET FirstName = @FirstName,
            LastName = @LastName,
            [password] = @Password
        WHERE UserName = @UserName
    END
END

你能帮我吗？

Answer 1

你可以添加＆＃34; = NULL＆＃34;在@password参数之后。

alter procedure EditUserInfo
(@FirstName nvarchar(100),
@LastName nvarchar(200),
@UserName nvarchar(100),
@Password binary = NULL
)
as
begin
    if (@Password IS NULL)
        BEGIN
            UPDATE UserAcount
            SET 
                FirstName = @FirstName , 
                LastName = @LastName
            where UserName = @UserName
        END
    ELSE
        BEGIN
            UPDATE UserAcount
            SET 
                FirstName = @FirstName , 
                LastName = @LastName, 
                [Password] = @Password 
            where UserName = @UserName
        END
end

Answer 2

ALTER PROCEDURE dbo.EditUserInfo
(
    @FirstName NVARCHAR(100),
    @LastName NVARCHAR(200),
    @UserName NVARCHAR(100),
    @Password BINARY = NULL
)
AS BEGIN

    SET NOCOUNT ON

    UPDATE dbo.UserAcount
    SET FirstName = @FirstName,
        LastName = @LastName,
        Password = ISNULL(@Password, Password)
    WHERE UserName = @UserName

END

我的tsql查询有什么问题？
