1136 - Column count doesn't match value count at row 1

This error message typically occurs when you are trying to insert data into a table where the number of columns in the table does not match the number of values that you are trying to insert.

For example, suppose you have a table with five columns, but you are trying to insert data for only four columns. In this case, you will receive the "Column count doesn't match value count at row 1" error message because the number of columns specified in the INSERT statement does not match the number of columns in the table.

To resolve this error, you need to ensure that the number of columns specified in the INSERT statement matches the number of columns in the table. Alternatively, you can explicitly specify the columns for which you are providing data in the INSERT statement, which helps to avoid errors if the table structure changes over time.

For example, instead of writing:

INSERT INTO my_table VALUES (1, 'John', 'Doe');

You could write:

INSERT INTO my_table (id, first_name, last_name) VALUES (1, 'John', 'Doe');

This way, if another column is added to the table in the future, your INSERT statement will not fail because you have explicitly specified which columns you are inserting data for.
