sql-server - 如何在 SQL Server 2005 中连接两个字符串

Question

我想连接“dummy's”和“dock”这两个词。

如何在 SQL Server 2005 中连接它们？支持双引号吗？

Answer 1

试试这个:

DECLARE @COMBINED_STRINGS AS VARCHAR(50); -- Allocate just enough length for the two strings.

SET @COMBINED_STRINGS = 'rupesh''s' + 'malviya';
SELECT @COMBINED_STRINGS; -- Print your combined strings.

或者您可以将字符串放入变量中。这样:

DECLARE @COMBINED_STRINGS AS VARCHAR(50),
        @STRING1 AS VARCHAR(20),
        @STRING2 AS VARCHAR(20);

SET @STRING1 = 'rupesh''s';
SET @STRING2 = 'malviya';
SET @COMBINED_STRINGS = @STRING1 + @STRING2;

SELECT @COMBINED_STRINGS; 

输出:

rupesh'smalviya

只需在字符串中添加一个空格作为分隔符即可。
