-----------------------------------
Summary: Support "CREATE TABLE ... LIKE" DDL
Key: CALCITE-6022
URL: https://issues.apache.org/jira/browse/CALCITE-6022
Project: Calcite
Issue Type: New Feature
Components: server
Affects Versions: 1.35.0
Reporter: hongyu guo
Fix For: 1.36.0
"CREATE TABLE ... LIKE" is SQL standard syntax, and some other dbms(mysql,
postgresql, sparksql) support it. So I think it is worth implementing.
syntax:
{code:java}
CREATE TABLE [IF NOT EXISTS] table_name
LIKE source_table [ like_option ... ]{code}
And for the `like_option`, I think the syntax of postgreSQL is more flexible
and powerful, and I believe it is reasonable to be similar to postgreSQL. But
there are not so many attributes in calcite, just keep CONSTRAINTS DEFAULTS and
ALL.
{code:java}
{ INCLUDING | EXCLUDING } { CONSTRAINTS | DEFAULTS | ALL }{code}
