Kasper Sørensen created METAMODEL-193:
-----------------------------------------
Summary: Query parser support for "CAST <field> AS <type>"
expression
Key: METAMODEL-193
URL: https://issues.apache.org/jira/browse/METAMODEL-193
Project: Apache MetaModel
Issue Type: Improvement
Reporter: Kasper Sørensen
As a natural addition to the work with datatype-converter functions of
METAMODEL-192, we could also provide some syntax support for a pretty normal
way of converting/casting data types in SQL:
{code}
SELECT CAST id AS string FROM table
{code}
We have converter functions for strings, numbers, dates and booleans. But they
currently require you to use a function style syntax like:
{code}
SELECT TO_STRING(id) FROM table
{code}
Supporting both syntax styles would be nice for SQL users.
