Solution 1

Try split the string. One part is the 'ECR' chars, the other is the serial number 123456.....
Then increment the number part and construct a new string when done.

serialNumber += 1;

Or 

serialNumber = serialNumber + 1;

string newStr = ercString + serialNumber;

I'll let you figure how how to split the string.

i need SQL Query not C# statement

gvprabu 1-Mar-13 6:13am

For SQL query we ll write... but we need to use NUMERIC(20,0) for that number. Because INT and BIG INT Data type and all we cant able to use. Where you are going to use this?

Solution 2

Hi

Try the following way....

SQL

DECLARE @SNo VARCHAR(30)='ECR12345432123456543216', @NextSNo VARCHAR(30)=''
 
SELECT @NextSNo='ECR'+RIGHT('00000000000000000000'+CAST(CAST(SUBSTRING(@SNo,4, 20) AS numeric(20,0))+1 AS VARCHAR(20)),20)
 
SELECT @SNo 'SNo', @NextSNo 'NextSNo'

Regards,
