Question

I'm trying to truncate sales_flat_order table. But i got below error

#1701 - Cannot truncate a table referenced in a foreign key constraint
(`dbmigrate1`.`sales_recurring_profile_order`, CONSTRAINT
`FK_7FF85741C66DCD37A4FBE3E3255A5A01` FOREIGN KEY (`order_id`)
REFERENCES `dbmigrate1`.`sales_flat_order` (`entity_id`))

But

Delete from sales_flat_order

But actually I want to truncate the table.

Answer 1

You can run this SQL query:

 select @order_id:=entity_id from sales_order_entity where increment_id='100000001';
delete from sales_order_entity where entity_id=@order_id or parent_id=@order_id;
