Parsing in Oracle SQL


I need help with parsing a column in Oracle.  Please see attached is the example of the current dataset and expected outcome. In the attached spreadsheet,"DIFFCOLS" column stores data separated in a new line and with colons(:). I need them parsed into 3 separate columns(Column name, src and tgt) and rows based on the serial number that is key value. Please see attached is the example of the current dataset and expected outcome.

Thank you

Try this.  Change tab1 to your table.

select serial_number,
	regexp_substr(mystring,'[^:]+',1,1) column_name,
	regexp_substr(mystring,'[^:]+',1,2) src,
	regexp_substr(mystring,'[^:]+',1,3) tgt
from (
	select serial_number,
					'[^' || chr(10) || ']+',
	from tab1,
		table(select collect(level)
				from dual
			connect by level <= length(diffcols) - length(replace(diffcols, chr(10))) + 1)
