MySQL raises ER_STD_LOGIC_ERROR (code 3052, SQLSTATE HY000) when its engine hits an unexpected logical inconsistency while executing a built-in function.
ER_STD_LOGIC_ERROR (MySQL error 3052) signals a logic error inside a built-in function. Check the offending query, validate input types, and upgrade to a patched MySQL version to resolve the issue.
ER_STD_LOGIC_ERROR
MySQL reports ER_STD_LOGIC_ERROR when its execution engine detects a logic fault inside a built-in function call. The message shows the failing function name and a short description, helping you pinpoint where the inconsistency occurred.
The error was introduced in MySQL 5.7.5, so earlier versions will not emit it. It maps to SQLSTATE HY000, classifying it as a general runtime error.
The most common trigger is invalid or out-of-range input passed to functions like JSON_EXTRACT, ST_Distance, or spatial operators. MySQL's internal assertions fire when assumptions about data type or value boundaries break.
Corrupted indexes, incompatible collation settings, and memory exhaustion can also surface ER_STD_LOGIC_ERROR because they distort the engine's logical state.
First isolate the exact statement by enabling general_log or using Galaxy's query history panel. Re-run the query with EXPLAIN to inspect function arguments.
Validate data types and cast inputs explicitly. If the error persists on all inputs, upgrade to the latest minor release, as many logic faults are patched quickly.
Spatial queries sometimes pass NULL geometries. Wrap inputs with IFNULL or ST_IsEmpty checks to avoid invalid coordinates.
JSON operations can exceed the maximum depth. Use JSON_DEPTH to guard against deeply nested payloads before calling JSON_EXTRACT.
Always sanitize user input at the application layer and enforce strict column types. Add CHECK constraints or triggers to reject bad values early.
Keep MySQL up to date and run nightly ANALYZE TABLE commands to detect corruption before it triggers runtime faults.
ER_DATA_OUT_OF_RANGE (1264) surfaces when numeric limits are exceeded; cast or clamp values to resolve it.
ER_SP_EXCEPTION_HANDLED (1644) denotes a SIGNAL statement inside stored routines; handle exceptions explicitly to avoid masking logic problems.
Passing NULL, out-of-range numbers, or badly formatted strings to built-in functions breaks internal assumptions.
Physical corruption in underlying storage can trigger engine assertions during function evaluation.
Some MySQL releases shipped with logic bugs fixed in later patches; upgrading removes these defects.
Low memory or thread exhaustion can cause partial evaluation states that surface as logic errors.
Raised when numeric input exceeds column limits. Fix by casting or resizing the column.
Indicates a stored procedure SIGNAL was caught. Review error handling logic.
Occurs when function arguments are of incompatible types. Ensure correct casts.
No. Most cases stem from invalid inputs or software bugs, not physical corruption.
No. Continuing may yield incorrect results. Fix inputs or upgrade MySQL.
Permissions do not trigger ER_STD_LOGIC_ERROR. It is purely a runtime logic fault.
Galaxy's AI copilot validates query syntax and suggests casts, reducing invalid function calls that lead to ER_STD_LOGIC_ERROR.
