Question

我试图从SQL服务器中的字符串中获取SO＃而不使用UDF。例子：

this is the SO#12345 55
this is the SO12345 55
this is the SO 12345 55
this is the SO#12345/55

我想只获取12345，无论特殊字符和空格如何。

Answer 1

DECLARE @Table1 TABLE 
    (VAL varchar(23))
;

INSERT INTO @Table1
    (VAL)
VALUES
    ('this is the SO#12345 55'),
    ('this is the SO12345 55'),
    ('this is the SO 12345 55'),
    ('this is the SO#12345/55')
;


SELECT LEFT(subsrt, PATINDEX('%[^0-9]%', subsrt + 't') - 1) 
FROM (
    SELECT subsrt = SUBSTRING(val, pos, LEN(val))
    FROM (
        SELECT val, pos = PATINDEX('%[0-9]%', val)
        FROM @Table1
    ) d
) t
