ColumnStore Insert
The INSERT statement allows you to add data to tables.
Syntax
INSERT INTO tbl_name [(col,...)] {VALUES | VALUE} ({expr | DEFAULT},...),(...),...
The following statement inserts a row with all column values into the customer table:
INSERT INTO customer (custno, custname, custaddress, phoneno, cardnumber, comments) VALUES (12, ‘JohnSmith’, ‘100 First Street, Dallas’, ‘(214) 555-1212’,100, ‘On Time’)
The following statement inserts two rows with all column values into the customer table:
INSERT INTO customer (custno, custname, custaddress, phoneno, cardnumber, comments) VALUES (12, ‘JohnSmith’, ‘100 First Street, Dallas’, ‘(214) 555-1212’,100, ‘On Time’), (13, ‘John Q Public’, ‘200 Second Street, Dallas’, ‘(972) 555-1234’, 200, ‘LatePayment’);
INSERT SELECT
With INSERT ... SELECT, you can quickly insert many rows into a table from one or more other tables.
- ColumnStore ignores the ON DUPLICATE KEY clause.
- Non-transactional INSERT ... SELECT is directed to ColumnStores cpimport tool by default, which significantly increases performance.
- Transactional INSERT ... SELECT statements (that is with AUTOCOMMIT off or after a START TRANSACTION) are processed through normal DML processes.
Autoincrement
Autoincrement is not supported by MariaDB ColumnStore.
