Split columns without breaking query folding
Hello,
I would like to split text column (textColumn below) by delimiter (" ") without breaking query folding, is it possible?
The table has data like this:
| textColumn | Split#1 | Split#2 |
| ABC DEF | ABC | DEF |
| A.111 GHI | A.111 | GHI |
| A.123 FFF | A.123 | FFF |
| A.22 EEE | A.22 | EEE |
Thanks
Hi CatoD ,
Query folding is the ability to convert M-code into native queries and process the data with the help of the data source, thus improving performance. Let's assume that the data source is some relational database, and combining the file content and SQL split statements, my answer is that the split columns cannot trigger query folding.
