<p>MySQL raises ER_WRONG_VALUE (error 1525) when a supplied literal cannot be interpreted as the expected data type or format for the target column.</p>
<p>MySQL Error 1525 ER_WRONG_VALUE occurs when the server cannot convert a provided value to the required data type, such as an invalid date or numeric format. Correct the literal or cast it properly to resolve the issue.</p>
Incorrect %s value: '%s'
MySQL emits Error 1525 ER_WRONG_VALUE when the server receives a literal it cannot coerce into the required data type. The placeholder %s in the official message resolves to the type name, and the second %s shows the offending value. The failure happens before any data is written, so no partial rows are stored.
The statement that produces ER_WRONG_VALUE is aborted and rolled back, meaning inserts, updates, and loads fail entirely. Applications may surface generic 500 errors, batch jobs may stop, and stored procedures may exit early. Quick diagnosis avoids missing data and broken downstream processes.
Locate the column listed in the error, inspect its data type, and verify the literal or bound parameter matches that type. Convert strings to the proper format with CAST or STR_TO_DATE, sanitize user input, or widen the column to accommodate the incoming value. Re-run the statement once all values conform.
Invalid date strings like "2023-31-12", numeric values containing commas, and ENUM assignments using undefined labels are frequent triggers. Adjusting the format or using the correct enum member resolves the error immediately. See the code samples below for exact syntax.
Validate and cleanse data at the application boundary, employ prepared statements with correct parameter types, and add CHECK constraints or generated columns that fail fast on bad formats. Continuous integration tests with realistic fixtures catch type mismatches before production.
Galaxy's AI copilot understands your schema and highlights type mismatches in real time. The editor flags literals that cannot be cast to the target column and offers context-aware fixes, reducing trial and error. Shared, endorsed queries ensure that only validated SQL reaches production pipelines.
Supplying a string like "2023-31-12" for a DATE column or "25:61:00" for a TIME column triggers ER_WRONG_VALUE.
Commas, currency symbols, or letters inside a value destined for INT or DECIMAL columns cause the conversion failure.
Inserting a label that is not part of the column's ENUM set results in a wrong value error.
Setting an invalid default, such as DEFAULT 'abc' on an INT column, raises the error at table creation time.
Passing malformed JSON text into a column typed JSON makes MySQL reject the value with ER_WRONG_VALUE.
Occurs when a string cannot be stored due to character set issues.
Raised when only part of a datetime is parsed successfully.
Indicates the value was shortened to fit the column, potentially losing data.
Appears when a NOT NULL column receives a NULL value instead of the required literal.
Yes. MySQL aborts the current statement and rolls back any changes in the same transaction, maintaining data integrity.
The server message shows the literal. Executing SHOW WARNINGS reveals it again, even in batch scripts.
Use INSERT IGNORE to downgrade the error to a warning, but verify that silent data loss is acceptable before doing so.
Galaxy suggests schema-aware fixes and automatically applies safe CAST statements or highlights invalid literals for manual correction.
