Question

如何在ms SQL server中搜索区分大小写的数据，如 user_name 和密码。在MySQl中，它由 BINARY（）函数完成。

Answer 1

使用区分大小写的collate创建列，并尝试以下操作：

<强>查询：

DECLARE @temp TABLE
(
      Name VARCHAR(50) COLLATE Latin1_General_CS_AS
)

INSERT INTO @temp (Name)
VALUES 
    ('Ankit Kumar'),
    ('DevArt'),
    ('Devart')

SELECT * 
FROM @temp
WHERE Name LIKE '%Art'

<强>输出：

DevArt

或尝试使用此类似代码 -

DECLARE @temp TABLE (Name NVARCHAR(50))

INSERT INTO @temp (Name)
VALUES 
    ('Ankit Kumar'),
    ('DevArt'),
    ('Devart')

SELECT * 
FROM @temp
WHERE Name LIKE '%Art' COLLATE Latin1_General_CS_AS

Answer 2

可以使用Casting to Binary

来完成此操作

SELECT * FROM UsersTable
WHERE   
    CAST(Username as varbinary(50)) = CAST(@Username as varbinary(50))
    AND CAST(Password as varbinary(50)) = CAST(@Password as varbinary(50))
    AND Username = @Username 
    AND Password = @Password
