我如何从这样存储的SQL表中获取数字 <PersonNumber> 013870 </PersonNumber>

Question

我有一个表，用于存储诸如ABC这样的信息，我只想在两者之间插入文本。

Answer 1

simple demo

declare @test table 
(
    xmlElement varchar(1000)
)
insert into @test
values ('<PersonNumber>013870</PersonNumber>')

-- select numbers from xml in the given format
select 
    cast(SUBSTRING(xmlElement, 15 , CHARINDEX('</PersonNumber>',xmlElement)-15) as int) -- 15 is position where number starts, because 14 is legth of <PersonNumber>
from @test 

-- result is 13870

In Oracle there is * REGEXP_SUBSTR * you can use it if you are oracle to get the number you want ans this is an example for you:

SELECT
  REGEXP_SUBSTR('500 Oracle Parkway, Redwood Shores, CA',
                ',[^,]+,') "REGEXPR_SUBSTR"
  FROM DUAL;

REGEXPR_SUBSTR
-----------------
, Redwood Shores,

If PersonNumber is fixed length you can simply use substring function.

Otherwise use

select Substring(PersonNumber, Patindex('%>%',PersonNumber) + 1, Patindex('%< /%',PersonNumber) - Patindex('%>%',PersonNumber)-1)

Try this as Sample:

DECLARE @z VARCHAR(32) = ',ukasd10,';
SELECT REPLACE(SUBSTRING(@z, CHARINDEX(',', @z), LEN(@z)), ',', '') AS Sample

and use this logic wherever you want...thanks!

With SQL Server, you can use an XML method if the column contains well-formed XML:

SELECT CAST(YourColumn AS xml).value('/Request[1]/Schedule[1]/Employees[1]/PersonIdentity[1]/PersonNumber[1]', 'int') AS PersonNumber
FROM dbo.YourTable;
