MySQL throws error 1349 when a view definition includes a subquery (derived table) in the FROM clause on server versions prior to 5.7.6.
MySQL Error 1349: ER_VIEW_SELECT_DERIVED appears when you create or alter a view that selects from a subquery in the FROM clause. Rewrite the view to eliminate the derived table or upgrade to MySQL 5.7.6+ to resolve the issue.
View's SELECT contains a subquery in the FROM clause
Error 1349 fires when MySQL encounters a view definition that references a derived table - a subquery inside the FROM clause. Versions before 5.7.6 reject this pattern to avoid recursion and dependency issues.
Although the condition was removed in 5.7.6, many legacy systems and dump files still trigger it. Fixing it is critical because the view remains unusable until adjusted or the server upgraded.
Using SELECT ... FROM (SELECT ...) AS alias inside a CREATE VIEW statement violates older MySQL parsing rules. Any nested SELECT in the FROM list is treated as a derived table and blocks view creation.
Attempts to ALTER an existing view to include such a subquery also raise the same error. Replication from a newer server to an older replica can surface the problem during schema migration.
The simplest remedy is to upgrade the server to MySQL 5.7.6 or later, where the restriction no longer exists. If upgrade is impossible, refactor the view.
Refactoring involves materializing the inner query as a separate view or table, then referencing it directly. Galaxy’s AI copilot can auto-rewrite the statement and validate the new view instantly.
Dump files from MySQL 8 restored into 5.6 will fail on views with derived tables. Edit the dump to reorder view creation or add compatibility flags.
Legacy reporting databases often store complex analytics in views. Split multi-level subqueries into intermediate views to satisfy 5.6 and earlier.
Target MySQL 5.7+ for all environments when possible. Maintain version-locked Docker images so CI mirrors production.
Run schema linters in Galaxy before migrations. The tool highlights derived tables in view definitions and offers one-click rewrites, reducing deployment surprises.
Error 1356 - ER_VIEW_SELECT_CLAUSE triggers on disallowed clauses in view SELECT. Fix by removing ORDER BY or LIMIT outside of subqueries.
Error 1369 - ER_VIEW_NO_EXPLAIN arises when EXPLAIN is attempted on views with certain constructs. Upgrade MySQL or unwrap the view for analysis.
A subquery wrapped in parentheses inside the FROM block is the primary trigger on pre-5.7.6 servers.
Dumping or replicating a view created on MySQL 8 into a 5.6 slave leads to instant failure.
Adding analytic logic to an existing view without checking version compatibility produces the error.
Some ORMs generate nested queries automatically, unintentionally violating older MySQL restrictions.
Raised when disallowed clauses like ORDER BY or LIMIT appear outside of subqueries in a view definition.
Occurs if a user variable is referenced in a view SELECT list.
Prevents EXPLAIN on views that contain constructs the optimizer cannot process.
No. MySQL removed ER_VIEW_SELECT_DERIVED in version 5.7.6. Views with derived tables work natively on 5.7 and 8.0.
No server variable bypasses the restriction. You must upgrade or rewrite the view.
Yes. You can store the subquery result in a temporary or permanent table and reference it from the view.
Galaxy’s AI copilot rewrites non-compliant views, and the editor’s linter flags derived tables before deployment, preventing runtime errors.
