Database Error

What This Error Means

This error occurs when the database encounters an unexpected value in a column. In this case, it is trying to insert a 'NULL' value into a column that only accepts integers.

Why It Happens

This error can occur when there is a mismatch between the data type of a column and the value being inserted. It can also happen when the database is unable to convert a given value to the expected type.

How to Fix It

1. 1To resolve this issue, check the data being inserted to ensure it matches the data type of the column. If the value is indeed null, you may need to remove the null value or replace it with a default value. If the value is not null, you may need to update the column type to accommodate the value being inserted.

Example Code Solution

INSERT INTO customers (name, age) VALUES ('John Doe', NULL);

INSERT INTO customers (name, age) VALUES ('John Doe', 30);
