<p>MySQL raises this error when the stored checksum for a view definition no longer matches the checksum it recalculates, signaling possible corruption or incompatibility.</p>
<p>MySQL Error 1392: ER_VIEW_CHECKSUM appears when the server cannot verify a view’s text checksum, often after upgrades, charset changes, or replication drift. Recreate the view with CREATE OR REPLACE VIEW or run mysql_upgrade to resync system tables and the error disappears.</p>
View text checksum failed
MySQL throws "Error 1392 (HY000): View text checksum failed" when the checksum stored with a view does not match the checksum the server recomputes at runtime. The mismatch makes MySQL treat the view as corrupted and blocks its use.
The checksum is derived from the CREATE VIEW statement, character set, collation, and algorithm. Any change that alters these components without updating the metadata triggers ER_VIEW_CHECKSUM.
Charset or collation changes between servers introduce different byte sequences, altering the calculated checksum.
Upgrading MySQL without running mysql_upgrade leaves outdated definitions in mysql system tables, producing checksum mismatches.
Manual edits to mysql.proc or mysql.views tables can corrupt stored checksums and lead to the error.
Replication lag, incomplete dumps, or partial restores may copy a view definition but not its correct checksum, causing drift on replicas.
The fastest remedy is to recreate the affected view using CREATE OR REPLACE VIEW; this writes a fresh checksum matching the current server context.
If the error appears after an upgrade, run mysql_upgrade to automatically rebuild all views and align their checksums.
Use mysqldump with --routines and --events, then reload the dump to refresh checksums on all objects consistently.
After cloning a schema between servers with different default collations, ER_VIEW_CHECKSUM arises; specifying COLLATE in a CREATE OR REPLACE VIEW statement resolves it.
On a replica that has diverged, dropping and re-importing only the problematic view synchronizes definitions without full resync.
Always run mysql_upgrade immediately after version upgrades to refresh internal metadata.
Dump and restore views using mysqldump rather than direct table copies to preserve consistent checksums.
Maintain identical character set and collation settings across primary and replica servers.
Use Galaxy’s version-controlled Collections to store canonical CREATE VIEW scripts so teams can easily recreate views if issues arise.
ER_VIEW_INVALID (1393) signals an invalid view definition; recreating the view also resolves it.
ER_NO_SUCH_TABLE (1146) occurs when underlying tables are missing; restore or recreate the tables before recreating the view.
Different default charsets between source and target servers change the binary representation of the view text, breaking the checksum.
An in-place binary upgrade leaves legacy definitions in mysql system tables, so recomputed checksums no longer match.
Direct edits to mysql.proc or mysql.views bypass checksum recalculation and corrupt stored values.
Lag or interrupted dumps copy definitions without updated checksums, creating inconsistencies on replicas.
Indicates an invalid view definition; often fixed by recreating the view or correcting underlying tables.
Occurs when a view references a table in a database without proper privileges; grant privileges or change the view owner.
Raised when a view’s underlying table is missing; recreate or restore the table before accessing the view.
No, a view stores no data. Recreating only rewrites metadata and checksum.
Ignoring is risky. The mismatch signals possible corruption. Always recreate or verify the view.
The upgrade changed internal metadata. Running mysql_upgrade or recreating the view aligns checksums.
Galaxy stores CREATE VIEW scripts in version-controlled Collections, letting teams quickly rebuild views after schema changes or upgrades.
