有没有一种方法可以将字符串(来自特定列)拆分为 n 个字符而不破坏单词,并且每个结果都在自己的行中?
示例:
2012-04-24 Change request #3 for the contract per terms and conditions and per John Smith in the PSO department Customer states terms should be Net 60 not Net 30. Please review signed contract for this information.
结果:
2012-04-24 Change request #3 for the contract per terms and conditions and per John Smith in the
PSO department Customer states terms should be Net 60 not Net 30.
Please review signed contract for this information.
我知道我可以使用 charindex
来查找最后一个空格,但我不确定如何获取剩余的空格并将它们作为行返回。
最佳答案
尝试这样的事情。也许您可以创建以下实现的 SQL 函数。
DECLARE @Str VARCHAR(1000)
SET @Str = '2012-04-24 Change request #3 for the contract per terms and conditions and per John Smith in the PSO department Customer states terms should be Net 60 not Net 30. Please review signed contract for this information.'
DECLARE @End INT
DECLARE @Split INT
SET @Split = 100
declare @SomeTable table
(
Content varchar(3000)
)
WHILE (LEN(@Str) > 0)
BEGIN
IF (LEN(@Str) > @Split)
BEGIN
SET @End = LEN(LEFT(@Str, @Split)) - CHARINDEX(' ', REVERSE(LEFT(@Str, @Split)))
INSERT INTO @SomeTable VALUES (RTRIM(LTRIM(LEFT(LEFT(@Str, @Split), @End))))
SET @Str = SUBSTRING(@Str, @End + 1, LEN(@Str))
END
ELSE
BEGIN
INSERT INTO @SomeTable VALUES (RTRIM(LTRIM(@Str)))
SET @Str = ''
END
END
SELECT *
FROM @SomeTable
输出将是这样的:
2012-04-24 Change request #3 for the contract per terms and conditions and per John Smith in the
PSO department Customer states terms should be Net 60 not Net 30. Please review signed contract
for this information.
关于sql - 将 SQL Server 中的字符串拆分为最大长度,将每个字符串作为一行返回,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/10852612/
