  • 0

I am writing a SQL Function that will take in a decimal and return the base32 representation of that decimal.

My problem is with the decimal to ascii conversion.

I am allowed to run the following query and return an ascii character

‘SELECT CHAR( 65 )’ which returns ‘A’

However in my function when I am trying to build my output string of letters, I am having trouble casting a bigint into a char, then concatenate that char to the end of a another char(which would be my output).

Sample line of code: ‘SET @OutputChar = @OutputChar + CAST( ( @Output + 55 ) AS CHAR(255) )’

What is the proper way to cast a bigint to char and then concatenate that char to another?

Thanks

  1. How are you declaring @OutputChar?

    If you have:

    DECLARE @OutputChar CHAR(255)

    then every time you concantenate, it will truncate it to 255. CHAR includes the whitespace at the end, maybe you mean to use varchar instead of CHAR?
