SQL 服务器字符串解析？

Question

DROP TABLE IF EXISTS #test

CREATE TABLE #test 
(
     line VARCHAR(500)
)

INSERT INTO #test (line)
VALUES ('1194125598,,191,3.95,194.95,Loan Payment,999999999,2779,"Melinda","Meeken",99999999,"m_welborn@yahoo.com , smeeken@gmail.com",10/28/2020 11:13')
        

SELECT 
    line,
    REPLACE(line,'%"%,%"%', '%"%|%"%')
FROM #test t

我有来自字符串的供应商信息，我正在尝试更新 #line 以删除两封电子邮件之间的逗号 (,)。有人有什么建议吗？

期望输出：'1194125598,,191,3.95,194.95,Loan Payment,999999999,2779,"Melinda","Meeken",99999999,"m_welborn@yahoo.com smeeken@gmail.com",10/28/2020 11:13'

Answer 1

假设只有两封电子邮件和一个逗号，请尝试以下操作：

DECLARE @Test table ( line varchar(500) );
INSERT INTO @Test VALUES
    ( '1194125598,,191,3.95,194.95,Loan Payment,999999999,2779,"Melinda","Meeken",99999999,"m_welborn@yahoo.com , smeeken@gmail.com",10/28/2020 11:13' );

SELECT
    STUFF (
        line,
        CHARINDEX ( ',', line, CHARINDEX ( '@', line ) ),
        1,
        ''
    ) AS new_line
FROM @Test;

Returns
