View's SELECT and view's field list have different column
MySQL raises Error 1353 - ER_VIEW_WRONG_LIST when a CREATE VIEW or ALTER VIEW statement supplies an explicit column list that differs in count from the columns produced by its SELECT clause. The database engine validates both lists during view compilation and stops execution if the counts disagree.
The issue can involve either too many names in the column list or too few columns selected. Because views act like virtual tables, this mismatch would break downstream queries that rely on a stable column schema.
The error appears at compile time of a CREATE VIEW, CREATE OR REPLACE VIEW, or ALTER VIEW statement. It is version-agnostic and occurs in MySQL 5.x, 8.x, and compatible MariaDB releases.
Developers often see it after adding or removing expressions in the SELECT clause without updating the optional column list, or when copying view definitions between environments with slight schema differences.
Leaving the view in an invalid state blocks deployment pipelines and prevents applications from running migrations. Users cannot query or refresh the view until the definition is corrected, risking service downtime or inconsistent reporting.
Promptly fixing the mismatch keeps database schemas consistent and avoids cascading errors in stored procedures, ORMs, and BI tools that reference the view.
The primary cause is a count mismatch between the explicit column list and the SELECT list. Secondary factors include forgotten wildcard expansion, conditional SELECT logic inside UNIONs, and accidental duplicate column names that MySQL rewrites or removes.
Align the number of column aliases with the number of expressions returned by the SELECT statement. The fix usually involves one of three actions: add missing column aliases, remove extra aliases, or adjust the SELECT list to match.
Developers frequently run into the error after adding a new calculated column to a view for analytics, or when cleaning up unused columns. Reviewing the view definition with SHOW CREATE VIEW and comparing the alias list to the SELECT clause quickly highlights mismatches.
Always omit the optional column list unless you need to rename columns. Prefer explicit aliasing inside the SELECT clause. Incorporate automated schema reviews in CI pipelines to catch mismatches before they reach production. Galaxy's SQL editor surfaces column counts and warnings in real time, helping you spot issues early.
Similar view-related errors include ER_VIEW_SELECT_CLAUSE (1291), ER_VIEW_SELECT_VARIABLE (1351), and ER_ALTER_VIEW_NO_CHANGE (1367). Each involves view definition problems but differs in root cause and resolution steps.
Providing more aliases than SELECT expressions triggers the mismatch.
Supplying fewer aliases than expressions leaves unnamed columns, causing the error.
Using a wildcard can expand to additional columns that exceed the alias list.
Different SELECT branches in a UNION may return varying column counts, confusing the alias list.
Occurs when a view's SELECT contains disallowed constructs.
Raised when a SELECT list references variables not allowed in views.
Triggered when ALTER VIEW makes no effective change to the definition.
No. If you omit it, MySQL names columns using the aliases in the SELECT clause, reducing mismatch risk.
Not always, but it can if the expanded columns outnumber your alias list.
Yes. Use CREATE OR REPLACE VIEW or ALTER VIEW with a corrected definition.
Galaxy’s editor counts SELECT columns in real time and warns when the alias list does not match, preventing the mismatch before execution.
