MariaDB Error 1276: Ambiguous Field Resolution
Description
This warning indicates that a column or reference within a SELECT statement (often a subquery or derived table) was implicitly resolved from an outer SELECT statement, rather than its immediate scope. While not always an error, it can lead to unexpected query results if the field resolution is not what was intended by the query author. It highlights potential ambiguity in column naming or query structure.
Error Message
Field or reference '%s%s%s%s%s' of SELECT #%d was resolved in SELECT #%d
Known Causes
3 known causesUnqualified Column Names
Using a column name in a subquery or nested SELECT statement without explicitly specifying its table alias, causing the database to resolve it from an outer query's scope.
Complex Nested Queries
Deeply nested SELECT statements or complex query structures where column names might be identical across different query levels, leading to unintended resolution by the database engine.
Conflicting Names in Views/Derived Tables
When a column name within a view definition or a derived table conflicts with a column name in the outer query, causing the field to be resolved unexpectedly from the outer context.
