MySQL Error 1525: Incorrect Value Provided
Description
MySQL Error 1525, 'Incorrect value', indicates that a value provided in a SQL statement, configuration, or function call does not meet the required data type, format, or constraint. This error typically arises when attempting to store data in a column with an incompatible type, assigning an out-of-range value, or using an invalid literal for a specific context.
Error Message
Incorrect %s value: '%s'
Known Causes
4 known causesData Type Mismatch
Attempting to insert a value into a column that has a different data type (e.g., text into an integer column or a non-numeric value into a numeric field).
Invalid Literal Format
Providing a value that doesn't conform to the expected format for its type (e.g., an incorrectly formatted date string for a DATE column, or a malformed JSON string).
Value Out of Range
Supplying a numeric value that exceeds the maximum or falls below the minimum allowed for its column type, system variable, or a specific function's parameter.
Invalid ENUM/SET Value
Providing a string value for an ENUM or SET column that is not among its predefined allowed values.
Solutions
3 solutions available1. Validate Input Data Type and Format easy
Ensure the data being inserted or updated matches the column's expected data type and format.
1
Identify the column and the value causing the error. The error message `Incorrect %s value: '%s'` will typically show the data type and the problematic value.
2
Check the data type of the target column. For example, if the column is an `INT`, ensure you are providing a valid integer and not a string with non-numeric characters. If it's a `DATE` or `DATETIME`, ensure the format is `YYYY-MM-DD` or `YYYY-MM-DD HH:MM:SS` respectively.
DESCRIBE your_table_name;3
Correct the value in your `INSERT` or `UPDATE` statement to conform to the column's data type and format. For instance, if you're trying to insert 'abc' into an INT column, change it to a valid integer like 123.
UPDATE your_table_name SET your_column_name = 'valid_value' WHERE condition;4
If the data comes from an application, review the application code to ensure it's correctly formatting and validating data before sending it to the database.
2. Check for Reserved Keywords or Special Characters easy
Ensure the provided value is not a MySQL reserved keyword or contains characters that might be misinterpreted.
1
Examine the problematic value for any MySQL reserved keywords (e.g., `SELECT`, `INSERT`, `UPDATE`, `WHERE`, `FROM`, `NULL`, `DEFAULT`).
2
If the value is a reserved keyword, enclose it in backticks (`) to treat it as an identifier rather than a command. For example, if the value is 'SELECT', use `` `SELECT` ``.
UPDATE your_table_name SET your_column_name = '`SELECT`' WHERE id = 1;3
Be cautious with special characters like single quotes (') within string values. If the value itself contains a single quote, it needs to be escaped by doubling it (e.g., 'O''Malley').
UPDATE your_table_name SET your_column_name = 'It''s a test' WHERE id = 2;3. Verify Column Constraints and Definitions medium
Ensure the value complies with any `CHECK` constraints, `ENUM` definitions, or other column-level rules.
1
Inspect the `CREATE TABLE` statement or use `SHOW CREATE TABLE your_table_name;` to review the column's definition, particularly for `ENUM` types or `CHECK` constraints.
SHOW CREATE TABLE your_table_name;2
If the column is an `ENUM`, verify that the provided value is one of the defined enum members. For example, if the enum is `('active', 'inactive')`, you cannot insert `'pending'`.
3
If there's a `CHECK` constraint, ensure the value satisfies the condition defined in the constraint. For example, a constraint like `CHECK (age > 0)` would reject a value of 0 or less.
4
Modify the input value to match the allowed options for `ENUM` types or satisfy the `CHECK` constraint. If the constraint is too restrictive for your data, consider altering the table definition.
ALTER TABLE your_table_name MODIFY your_column_name ENUM('active', 'inactive', 'pending');
