Please give a try with the below code and it should work and hope this helps:

Load distinct
SubField(column1,' ,') as column1,
column2,
column3,
column4
;

Load * inline [
column1|column2|column3|column4
AA, BB|123|456|789
AB,CC|234|678|123
AA|567|786|890
] (delimiter is '|');

there's no need of a preceding load, this can be done in a single pass

TableName:

Load subfield(column1,',') as column1,column2,column3,column4 inline [
column1|column2|column3|column4
AA, BB|123|456|789
AB,CC|234|678|123
AA|567|786|890
] (delimiter is '|');

thanks for your help,

this will work if I have few data. However, my database have more than 30 columns and 50000 rows.

What should I do in that case?
