@Muhammad Gelban , since the SqlStdOperatorTable.CAST is hard coded , I
think it's difficult to replace it absolutely with a new cast function now.

@Muhammad Gelban, I suggest you to find the the usages of an Operator
first , if you want to define a new one to replace it .
In this case, you will find that the SqlStdOperatorTable.CAST is used by
the Sql Converter, there're a few more places need attention.
You can refer to the solution of my
@Muhammad Gelbana，I think you just register an alias-name 'TEXT' for the
SqlType 'VARCHAR'.
The parser did the right thing here, see

I think you can reference the JdbcConvention , that would push queries to
JDBC datasource as much as possible,.

how about these:
[CALCITE-2973] Allow theta joins that have equi conditions to be executed
using a hash join algorithm
[CALCITE-2282] Allow OperatorTable to be pluggable in the parser
[CALCITE-2992] Enhance implicit conversions when generating hash join keys
for an equi condition
