How to determine if a string has duplicate characters and extract it out?
I now have a table with over 1000 columns and most of the column names have duplicate words that need to be extracted. Please ask the big guys, how to achieve this with JSL?
For example:
column name is abp-g5.GAIV_0099_P013_GAIV_0099_P013,then extract GAIV_0099_P013;
The column name is abp-g5.GAI1997_GAI1997, then extract GAI1997
