Remove leading zeros in SQL task

Hi all.

We have a table (myTable) that has a field (PO_Number) that may have leading zeros.

For example:


I want to know if there is a way to remove any leading zeros, the number of leading zeros may vary, some may not have any leading zeros.

I will use this in a SQL DTS.

Thank you in advance!

REPLACE(LTRIM(REPLACE([PO_Number], '0', ' ')), ' ', '0')

1. It replaces all 0s with spaces
2. Trims the leading spaces using LTRIM
3. replaces the spaces with 0s (in case there were any other zeros in the original text that were not leading)

Try this.

declare @x nvarchar(100)

--select @x = '87980123'
--select @x = '0087980123'
--select @x = '000087980123'
--select @x = '000087980123'
--select @x = 'asdasd87980123'
--select @x = '000asdasda87980123'
--select @x = 'adsa000adsd87980123'
select @x = 'sdadsa87980123'

while left(@x, 1) = '0'
    select @x = right(@x, len(@x) - 1)

select @x
