# I need help building a query that will parse data into a temp table

Posted on 2013-06-18

Hi Experts,
I have an integrated service that imports raw data from a text file into a SQL Server table.  I want to build a temp table using a SELECT query that will give me a column with transaction amounts, by parsing the raw data starting at position 20 for a length of 13 characters.  Once parsed, the data looks like the samples below.

I need to remove all leading 0's and then sum the amounts, and make the 2 right most characters decimals. How can I do this?  The raw data is originally imported to a varchar(250) column.

Sample of raw data:

0000000012500
00000000-1500
0000005200025
00000000-4500

The sum should be:  \$52,065.25

Many ways to do that, e.g.:
``````select sum(convert(money, substring(rawdata, patindex('%[-1-9]%', rawdata),100))/100) from
(select rawdata = '0000000012500'
union all
select '00000000-1500'
) data
``````

I would convert to decimal only at the end, to avoid any rounding issues:

SELECT CAST( SUM( CAST(SUBSTRING(raw_data, PATINDEX('%[^0]%', raw_data), 100) AS bigint) ) / 100.0 AS decimal(19, 2))
FROM (
SELECT '0000000012500' AS raw_data UNION ALL
SELECT '00000000-1500' UNION ALL
SELECT '0000005200025' UNION ALL
SELECT '00000000-4500'
) AS test_data
