Split comma separated values to columns in Oracle

Question

I have values being returned with 255 comma separated values. Is there an easy way to split those into columns without having 255 substr?

ROW  | VAL
--------

You can use regexp_substr():

select regexp_substr(val, '[^,]+', 1, 1) as val1, 
       regexp_substr(val, '[^,]+', 1, 2) as val2, 
       regexp_substr(val, '[^,]+', 1, 3) as val3, 
       . . .

I would suggest that you generate a column of 255 numbers in Excel (or another spreadsheet), and use the spreadsheet to generate the SQL code.
