MySQL Error 3700: Regular Expression Limit Exceeded
Description
This error indicates that a regular expression pattern used in a query has exceeded MySQL's internal limits on either its total length or its computational complexity. It typically occurs when the regex is too long, too complex, or poorly optimized, preventing the query from executing successfully.
Error Message
The regular expression pattern exceeds limits on size or complexity.
Known Causes
3 known causesExtremely Long Pattern String
The regular expression pattern's character count is excessively high, exceeding MySQL's internal buffer or length limits.
High Pattern Complexity
The pattern contains a large number of groups, alternations, lookaheads, or backreferences, making it computationally intensive to parse and execute.
Catastrophic Backtracking
The regex design allows for an exponential number of matching attempts on certain inputs, quickly reaching complexity thresholds and exhausting resources.
