Illegal value for type
Production Risk
Medium — inserts fail or data is silently mangled depending on sql_mode.
What this means
A value was supplied that is not legal for the target column type (e.g. inserting an invalid geometry or out-of-range ENUM/SET value).
Why it happens
- 1Inserting malformed WKT/WKB into a spatial column
- 2Using a value outside the defined ENUM members
- 3Bit-field value exceeding the column width
How to reproduce
trigger — this will error
trigger — this will error
INSERT INTO t (geom_col) VALUES (ST_GeomFromText('INVALID_WKT'));expected output
ERROR 1367 (HY000): Illegal non geometric '...' value found during parsing
Fix 1
Validate spatial values before insert
Validate spatial values before insert
SELECT ST_IsValid(ST_GeomFromText('POINT(0 0)'));Why this works
ST_IsValid confirms geometry is well-formed.
Fix 2
Use correct ENUM values
Use correct ENUM values
SHOW COLUMNS FROM t LIKE 'col';
Why this works
Reveals the permitted ENUM members.
