hongyu guo created CALCITE-6022: ----------------------------------- 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} Some related link [https://www.postgresql.org/docs/current/sql-createtable.html] [https://ronsavage.github.io/SQL/sql-2003-2.bnf.html#table%20definition] [https://dev.mysql.com/doc/refman/8.0/en/create-table-like.html] -- This message was sent by Atlassian Jira (v8.20.10#820010)
