我有记录，有时带有一个文本和一个数字，有时带有两个、三个或四个，它们用两个点“：”分隔。我想将数字和文本拆分为多列。
这里是一个记录示例： 3月：4月1日：5月2日：6月10日：1
想要的结果：
| Str_1 | item_1 | Str_2 | 项目_2 | Str_3 | 项目_3 | Str_4 | item_4 |
|---|---|---|---|---|---|---|---|
| 三月 | 1 | 四月 | 2 | 五月 | 10 | 六月 | 1 |
我正在使用 SQL SERVER 2012
我制作了这个脚本，但它并不适用于所有情况

Thanks!
我不确定那一大堆乱七八糟的代码应该做什么，但你可以使用
OPENJSONDECLARE @str varchar(max) = 'Text1 : 1 Text2 : 2 Text3 : 10 Text4 : 1';
SELECT
j.[key],
LEFT(j.value, v.pipe - 1),
SUBSTRING(j.value, v.pipe + 1, LEN(j.value))
FROM OPENJSON(
'["' +
REPLACE(
REPLACE(
@str,
' : ',
'|'
),
' ',
'","'
)
+ '"]'
) j
CROSS APPLY (VALUES (
CHARINDEX('|', j.value)
) ) v(pipe);
如果您希望将其放在一行上，则可以将其聚合。
