Removing Leading Zeros From Column in Table

-

Step 1: 

Improving the ResultSet
I had missed including all zeros in my sample set which was an overlook. Here is the new sample which includes all zero values as well.
USE tempdb
GO-- Create sample table

CREATE TABLE Table1 (Col1 VARCHAR(100))INSERT INTO Table1 (Col1)SELECT '0001'UNION ALLSELECT '000100'UNION ALLSELECT '100100'UNION ALLSELECT '000 0001'UNION ALLSELECT '00.001'UNION ALLSELECT '01.001'UNION ALLSELECT '0000'

Step 2:

SELECT CASE PATINDEX('%[^0 ]%', Col1 + ' ‘')WHEN 0 THEN ''ELSE SUBSTRING(Col1, PATINDEX('%[^0 ]%', Col1 + ' '), LEN(Col1))END
FROM Table1

 See the result.........

Adding a serial number in grouping without any code. I have placed the step by step screenshots which will explain easily how to do it.   1) Add a new field in Running Total Fields in Field Explorer   Give a proper name to your Running total name. For example I have choosen here RTotal0. Now categorize based on which field in database you want to summarize it. Next is as we want serial number select count. If you want your serial number to start again from the start when the value in the group changes then select on change of group and specify the grouping name else keep the default value.   Smaple Preview of the Design View of Report where I Have added SRNo column at the start in grouping section.
