I need some help stripping leading 0's from a string. The column name in the table is code. Here are some examples.

00345.0001

02345.0123

I need to be able to strip the leading zero's from the first part before the . and the second part after the . so that they return the following values.

345.1

2345.123

I have tried the following but it only strips the 0 from the beginning of the string.

select SUBSTRING(code, PATINDEX('%[^0]%', code+'.'), LEN(code))

from accountmain

where 1=1

and statusid = 1

Thank you in advance for your help.

Maybe something like this could work?



WITH SampleData AS(

    SELECT '00345.0001' code UNION ALL

    SELECT '02345.0123' code UNION ALL

    SELECT '025013'

)

SELECT ISNULL( CAST( CAST( PARSENAME(code, 2) AS INT) AS varchar( 10)) + '.', '')

    + CAST( CAST( PARSENAME(code, 1) AS INT) AS varchar( 10))

FROM SampleData

It works if I type in the values I need changing but when I modify your query to run against the accountmain table using the code field it returns me an error. Can't convert a nvarchar value to int.

WITH SampleData AS(

SELECT code from accountmain

)

SELECT ISNULL( CAST( CAST( PARSENAME(code, 2) AS INT) AS varchar( 10)) + '.', '')

+ CAST( CAST( PARSENAME(code, 1) AS INT) AS varchar( 10))

FROM SampleData

Msg 245, Level 16, State 1, Line 1

Conversion failed when converting the nvarchar value '0HOLD' to data type int.

I have some entries in that table that are not numbers. I need to run it against the whole table.

Fair enough. I thought you only had digits.

Check for the following. 😉



WITH SampleData AS(

    SELECT '00345.0001' code UNION ALL

    SELECT '02345.0123' code UNION ALL

    SELECT '025013' code UNION ALL

    SELECT '0HOLD.0250'

)

SELECT code,

     ISNULL( SUBSTRING(Lcode, PATINDEX('%[^0]%', Lcode), 50) + '.', '')

     + SUBSTRING(Rcode, PATINDEX('%[^0]%', Rcode), 50)

FROM SampleData

CROSS APPLY (SELECT PARSENAME(code, 2) AS Lcode, PARSENAME(code, 1) AS rcode) x
