How to Fix MySQL Error 1058 - SQLSTATE: 21S01 (ER_WRONG_VALUE_COUNT) Column count doesn't match value count

MySQL is a popular open-source relational database management system used by many websites and applications. However, like any software, it can encounter errors that can disrupt its normal operation. One such error is MySQL Error 1058 - SQLSTATE: 21S01 (ER_WRONG_VALUE_COUNT) Column count doesn't match value count. In this article, we will explore the causes of this error and provide solutions to fix it.

Understanding MySQL Error 1058

MySQL Error 1058 occurs when the number of columns specified in an INSERT statement does not match the number of values provided. This error typically happens when you try to insert data into a table and the number of columns in the table does not match the number of values you are trying to insert.

For example, let's say you have a table named "users" with three columns: "id", "name", and "email". If you try to insert data into this table with only two values, MySQL will throw Error 1058 because the number of columns and values don't match.

Causes of MySQL Error 1058

There are several reasons why you might encounter MySQL Error 1058:

  • You are trying to insert data into a table with a different number of columns than the values you are providing.
  • You are using an incorrect syntax in your INSERT statement.
  • You are trying to insert NULL values into columns that do not allow NULL.
  • You are using a different character set for the table and the values you are trying to insert.

Fixing MySQL Error 1058

To fix MySQL Error 1058, you can follow these steps:

1. Check the number of columns and values

Make sure the number of columns in your table matches the number of values you are trying to insert. If they don't match, you need to either add or remove columns in your table or provide the correct number of values in your INSERT statement.

2. Verify the syntax of your INSERT statement

Double-check the syntax of your INSERT statement to ensure it is correct. Make sure you are using the correct keywords and that the column names and values are properly formatted.

3. Check for NULL values

If any of the columns in your table do not allow NULL values, make sure you are not trying to insert NULL values into those columns. Either provide valid values or modify the table structure to allow NULL values if necessary.

4. Verify the character set

If you are using a different character set for the table and the values you are trying to insert, it can cause MySQL Error 1058. Make sure the character set is consistent for both the table and the values.

By following these steps, you should be able to fix MySQL Error 1058 and successfully insert data into your table without any issues.

Summary

In conclusion, MySQL Error 1058 - SQLSTATE: 21S01 (ER_WRONG_VALUE_COUNT) Column count doesn't match value count occurs when the number of columns specified in an INSERT statement does not match the number of values provided. To fix this error, you need to ensure the number of columns and values match, verify the syntax of your INSERT statement, check for NULL values, and verify the character set consistency.
