   <pre>This has been added in https://github.com/apache/arrow/pull/9243 but will require a change like:
   
   substring(c_phone from 1 for 2) 
   to
   substr(c_phone, 1, 2)
   </pre>

   <pre>Very good [~MikeSeddonAU]! I plan to release sqlparser with support for parsing the syntax here: https://github.com/ballista-compute/sqlparser-rs/pull/293 and upgrading DataFusion to use a newer version</pre>

   <pre>Great. I will need to get my head around the sqlparser so the rest of the strange ANSI syntax can be implemented like this: 
   
   overlay('Txxxxas' placing 'hom' from 2 for 4)</pre>
