<p>MySQL raises ER_DATETIME_FUNCTION_OVERFLOW when a datetime function receives a value outside the allowed range for the requested date or time part.</p>
<p>MySQL Error 1441 ER_DATETIME_FUNCTION_OVERFLOW appears when a datetime function overflows its valid range, such as extracting month 13 or day 32. Validate or cast your input data, clamp out-of-range values, and rerun the query to fix the issue.</p>
Datetime function: %s field overflow
Error 1441 fires when MySQL executes a datetime function (DATE_ADD, EXTRACT, TIMESTAMPDIFF, etc.) and the resulting value exceeds the legal range for that function or unit.
The server stops the statement, returns SQLSTATE 22008, and shows the message Datetime function: %s field overflow, where %s is the offending unit such as YEAR, MONTH, or DAY.
The overflow happens during arithmetic, extraction, or comparison operations that generate impossible calendar values, for example adding 40 days to 2024-02-15 or extracting MONTH from the string 2024-13-01.
It is common in ETL jobs, legacy data migrations, and poorly validated user input.
Unhandled overflow halts transactions, breaks applications, and can hide corrupt source data. Addressing it ensures data integrity, predictable query results, and smoother pipeline runs.
Invalid literals passed to DATE, DATETIME, or TIMESTAMP columns cause immediate overflow when parsed by functions.
Mathematical operations that shift a valid date out of range trigger the error at runtime.
Start by isolating the failing expression with SELECT statements. Check each date component for impossible values.
Cast or correct bad strings, constrain arithmetic, or wrap operations with functions such as GREATEST or LEAST to keep results inside valid bounds.
Bulk inserts that skip input validation often store 0000-00-00 or 9999-99-99; cleansing the source or using STR_TO_DATE with strict mode prevents later overflow.
Reports that calculate future dates should switch from DATE_ADD(..., INTERVAL n MONTH) to safer month_end logic or use LAST_DAY to clamp overflow.
Enable sql_mode='STRICT_ALL_TABLES' so invalid dates fail early at insert time.
Use CHECK constraints or generated columns in MySQL 8.0+ to enforce valid ranges.
SQLSTATE 22007 (invalid datetime format) occurs when the string cannot be parsed at all, while 1292 incorrect datetime value indicates a broader conversion failure. The fixes are similar: validate input and sanitize data.
Strings like '2024-13-01' or '1999-00-10' exceed month or day ranges and overflow when used in functions.
DATE_ADD or TIMESTAMPADD producing days beyond the end of a month or adding months that push the year past 9999 triggers overflow.
CSV or JSON imports that drop characters can produce malformed dates which later overflow on calculation.
Raised when a string cannot be parsed into any valid datetime; resolve by correcting the literal.
Appears during STR_TO_DATE when the format mask mismatches the input string.
Standard SQL state that overlaps with MySQL 1292; same remediation steps apply.
The month 13 is outside the valid 1-12 range, so MySQL throws ER_DATETIME_FUNCTION_OVERFLOW instead of returning NULL.
No. The overflow check is built into the server. Instead, validate data earlier or use IGNORE to skip bad rows during INSERT.
Strict mode mainly rejects bad inserts. Error 1441 arises inside functions regardless of mode, but strict mode helps prevent corrupted data that later overflows.
Galaxy's AI copilot validates query output ranges and highlights potential overflows before you run the statement, reducing runtime failures.
