Konstantin Orlov commented on IGNITE-14991:
-------------------------------------------
To enable such operators in parser we need to set the flag
\{{includePosixOperators}} to true (see
{{modules/calcite/src/main/codegen/config.fmpp}}) and add the following code to
the end of the \{{modules/calcite/src/main/codegen/includes/parserImpls.ftl}}:
{code:java}
<DEFAULT, DQID, BTID> TOKEN :
{
< NEGATE: "!" >
| < TILDE: "~" >
}
{code}
Problems with validation requires further investigation.
