Column count doesn't match value count at row

This error occurs when the number of columns specified in an SQL query does not match the number of values being inserted or updated in a particular row. This usually happens when there is a mistake in the SQL syntax or when the data being inserted or updated is not formatted correctly.

To fix this error, you need to carefully review your SQL query and ensure that the number of columns and values being inserted or updated match. You may also need to check the data being inserted or updated to make sure it is in the correct format and that there are no missing or extra values.

Here is an example of an SQL query that could cause this error:

INSERT INTO users (id, name, email) VALUES (1, 'John Doe', 'johndoe@example.com', 'password123');

In this case, there are only three columns specified (id, name, and email), but there are four values being inserted (id, name, email, and password). To fix the error, you would need to remove the extra value:

INSERT INTO users (id, name, email) VALUES (1, 'John Doe', 'johndoe@example.com');
