![]() ![]() In these examples I used the IGNORE option. So we get the same result as in the previous example. Now I’ll insert the same data and use OR IGNORE to skip over the row that violates the constraint. To demonstrate, I’ll drop the previous table and create it again, but without the ON CONFLICT clause: DROP TABLE IF EXISTS Products The difference is that, you replace ON CONFLICT with OR. You can also use this clause when inserting and updating data. Now if I try to insert NULL into the ProductName column that row is skipped. In this case I specified IGNORE, which means that, if there’s a constraint violation SQLite will skip over that row and then continue processing. In this case, I added the clause to a NOT NULL constraint. When you use the ON CONFLICT clause, you apply it to the specific constraint that you want to handle. Here’s an example of using ON CONFLICT at the time of creating the table. ![]() When Creating the TableĪs mentioned, you can use ON CONFLICT when you create the table or when you insert/update data. The ON CONFLICT clause is used in CREATE TABLE statements, but it can also be used when inserting or updating data by replacing ON CONFLICT with OR. This article provides examples and an explanation of each of these options. There are five possible options you can use with this clause: It applies to UNIQUE, NOT NULL, CHECK, and PRIMARY KEY constraints (but not FOREIGN KEY constraints). SQLite has the ON CONFLICT clause that allows you to specify how to handle constraint conflicts. ![]()
