测试T-SQL中的不等式

-- 示例1：比较两个数值
DECLARE @value1 INT = 5;
DECLARE @value2 INT = 10;

IF @value1 <> @value2
BEGIN
    PRINT 'The values are not equal.';
END

-- 示例2：比较两个字符串
DECLARE @string1 VARCHAR(10) = 'Hello';
DECLARE @string2 VARCHAR(10) = 'World';

IF @string1 <> @string2
BEGIN
    PRINT 'The strings are not equal.';
END

-- 示例1：比较两个数值
DECLARE @value1 INT = 5;
DECLARE @value2 INT = 10;

IF @value1 != @value2
BEGIN
    PRINT 'The values are not equal.';
END
