Description

MariaDB Error 1136 occurs when an `INSERT` or `UPDATE` statement attempts to provide a number of values that does not match the number of columns specified for the target table or query. This typically happens when the `VALUES` clause has a different count of items than the column list or the total columns in the table.

Known Causes

4 known causes

⚠️

Missing Column in INSERT

An `INSERT` statement explicitly lists fewer columns than the number of values provided in its `VALUES` clause.

⚠️

Extra Value in INSERT

The `VALUES` clause of an `INSERT` statement contains more values than the number of columns explicitly specified or implicitly available in the table.

⚠️

Implicit Column Count Mismatch

An `INSERT` statement omits the column list, and the number of values supplied doesn't match the total number of columns in the table.

⚠️

SELECT Subquery Mismatch

When using `INSERT INTO ... SELECT`, the number of columns retrieved by the `SELECT` statement does not align with the number of columns in the target table.

Solutions

2 solutions available

1. Match Column Count with Values easy

Ensure INSERT has same number of columns and values

1

Check your INSERT statement

-- Wrong: 3 columns but 2 values
INSERT INTO users (id, name, email) VALUES (1, 'John');

-- Correct: matching count
INSERT INTO users (id, name, email) VALUES (1, 'John', 'john@example.com');

2

Or specify only columns you have values for

INSERT INTO users (id, name) VALUES (1, 'John');

2. Check Table Structure easy

Verify actual columns in table

1

View table columns

DESCRIBE users;

2

Insert with explicit column list

-- Always specify columns explicitly
INSERT INTO users (name, email) VALUES ('John', 'john@example.com');
