ColumnStore Insert

The INSERT statement allows you to add data to tables.

1. Syntax "Syntax"

2. INSERT SELECT "INSERT SELECT"

3. Autoincrement "Autoincrement"

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’, ‘[phone]’,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’, ‘[phone]’,100, ‘On Time’),
  (13, ‘John Q Public’, ‘200 Second Street, Dallas’, ‘[phone]’, 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

Example

create table autoinc_test(
id int,
name varchar(10))
engine=columnstore comment 'autoincrement=id';

INSERT INTO autoinc_test (name) VALUES ('John');
INSERT INTO autoinc_test (name) VALUES ('Doe');
