MySQL Error 3186: Parser Capacity Exceeded
Description
This error indicates that the MySQL server's SQL parser encountered a query too complex or large to process within its internal limits. It typically occurs when a query involves an excessive number of joins, subqueries, or highly complex expressions, causing the parser to exhaust its resources and 'bail out'.
Error Message
Parser bailed out for this query.
Known Causes
3 known causesOverly Complex SQL Query
Queries with an excessive number of joins, deeply nested subqueries, or highly intricate expressions can exceed the parser's internal processing capacity.
Exceeding Internal Parser Limits
MySQL's parser has predefined internal limits on query size, recursion depth, or the total number of tokens, which a very large or deeply nested query might breach.
Very Large Literals or Expressions
Queries containing extremely long string literals, many constant values, or expansive 'IN' clauses can consume excessive parser memory and resources.
