SQL SERVER FOR XML PATH合并字符串

------------------------------------------------
SET STATISTICS TIME ON
DECLARE  @OrderStr  NVARCHAR(max) = ‘‘;

SELECT @OrderStr += a.SerialNumber+‘,‘
FROM dbo.WithdrawalsLog a

SET STATISTICS TIME OFF
------------------------------------------------

SET STATISTICS TIME ON

DECLARE  @OrderStr  NVARCHAR(max) = ‘‘;

SET @OrderStr = (
SELECT a.SerialNumber+‘,‘
FROM dbo.WithdrawalsLog a
FOR XML PATH(‘‘)
)

SET STATISTICS TIME OFF
------------------------------------------------

如果要获取某个表的字段,并把它拼接成一个字符串,那这个方法再好不过了:

SELECT bankcode+‘,‘+bankname+‘;‘   FROM BankInfo FOR XML PATH(‘‘)
