Question

我有一个名为“PONDAILY”的表，其中有一个名为“PONCOM”的列。 “PONCOM”具有字符串内容，如文本注释，我需要从字符串中仅提取SO编号，下面是列中数据如何查看和突出显示的示例。我不能使用任何UDF，因为我只能读取SQL服务器。

DELETE TO EXPEDITE ON NEW STO FOR M/D SO SAP# **5000068**.  HN04

DELETING FOR M/D SO#**4500000762** KF 03-31

Answer 1

如果我理解正确的问题：

select substring(PONCOM, t2.num, case when t3.not_num < t2.num then 8000 else t3.not_num - t2.num end)
  from PONDAILY p 
   cross apply (select charindex('SO', PONCOM, 1)) t1(so)
   cross apply (select patindex('%[0-9]%', substring(PONCOM, t1.so, 8000)) + t1.so - 1) t2(num)
   cross apply (select patindex('%[^0-9]%', substring(PONCOM, t2.num, 8000)) + t2.num - 1) t3(not_num)
