![]() MySQL added the clauses due to the fact that they were nullable columns. We can see that the table’s definition has DEFAULT clauses against both the ProductDescription column and the Price column, even though we didn’t specify those DEFAULT clauses when we created the table. ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci | `ProductDescription` varchar(1000) DEFAULT NULL, We can verify this by using SHOW CREATE TABLE to check the table’s definition: SHOW CREATE TABLE Products When we define a column without a NOT NULL clause, MySQL implicitly adds an explicit DEFAULT clause to the column. The reason those two columns didn’t produce an error is because they are nullable columns (i.e. ![]() Note that I didn’t provide any values for the ProductDescription and Price columns, but they didn’t cause an error. Result: Query OK, 1 row affected (0.00 sec) So for example, we could change the above INSERT statement to the following: INSERT INTO Products ( ProductId, ProductName ) If we get the error when trying to insert data, one solution is to ensure we provide a value for the column. MySQL returned an error because the column has no default value and it’s a NOT NULL column. In this case, I tried to insert a row into the table, but I didn’t specify a value for the ProductName column. Here’s another scenario that will produce the same error: INSERT INTO Products ( ProductId ) The reason for this is because the ProductName column doesn’t have a default value set and it’s specified as NOT NULL. Result: ERROR 1364 (HY000): Field 'ProductName' doesn't have a default value ProductId int NOT NULL AUTO_INCREMENT PRIMARY KEY,Īnd we now try to get the default value for the ProductName column: SELECT Suppose we create the following table: CREATE TABLE Products ( Here are some scenarios that will produce the error. Below are examples of how to fix this error. ![]() The solution to this issue will depend on what we’re trying to do. This can happen when the column is set to NOT NULL and hasn’t been defined with an explicit default value. If you’re getting MySQL error 1364, that reads something like Field ' column_name' doesn't have a default value, where column_name is the name of a column in your table, it’s probably because you’re trying to perform an operation that retrieves the column’s default value, but it doesn’t have a default value.
