CREATE TABLE LIKE
description
This statement is used to create an identical empty table based on the structure of another table.
Syntax:
CREATE [EXTERNAL] TABLE [IF NOT EXISTS] [database.]table_name LIKE [database.]table_name
Note:
- The replicated table structures include Column Definition, Partitions, Table Properties, etc.
SELECT
permission is required on the original table.- Support to copy external table such as MySQL.
Example
Under the test1 Database, create an empty table with the same table structure as table1, named table2.
CREATE TABLE test1.table2 LIKE test1.table1
Under the test2 Database, create an empty table with the same table structure as test1.table1, named table2.
CREATE TABLE test2.table2 LIKE test1.table1
Under the test1 Database, create an empty table with the same table structure as MySQL external table, named table2.
CREATE TABLE test1.table2 LIKE test1.table1
keyword
CREATE,TABLE,LIKE
