oracle sql splitting a comma-separated string but ignoring commas in quotes

Last Modified: 2020-03-19

Kindly help on the following problem. I am using Oracle SQL to split comma separated string values. However, need to ignore the values with comma.

Below is the sample data, which needs to be separated/split (comma seperated)
'franchise': 'Px Oncology (Solid Tumors, all XA Onc projects)', 'zlinical_xombination_study': 'No'

Open in new window

sample output would be,
franchise: Px Oncology (Solid Tumors, all XA Onc projects)
zlinical_xombination_study: No

Open in new window

problem is, the value 'franchise': 'Px Oncology (Solid Tumors, all XA Onc projects)' is also having a comma within its value, need to ignore this comma while splitting

I am using the below code,
select LTRIM (REGEXP_SUBSTR (ERROR_TEXT, '[^,]+', 1, 1), ',')    AS part_1 FROM ERROR_LOG_TEMP_5;

Open in new window

The output I am getting is ['franchise': 'Px Oncology (Solid Tumors]

It should provide,  ['franchise': 'Px Oncology (Solid Tumors, all XA Onc projects)']
