Error 1032 signals that MySQL cannot locate a requested row through the index, usually during UPDATE, DELETE, or replication, pointing to missing or corrupted data.
MySQL Error 1032: ER_KEY_NOT_FOUND appears when MySQL cannot locate a row through the specified index during an UPDATE, DELETE, or replication event. Sync data, rebuild indexes, or correct the WHERE clause to resolve the problem.
Can't find record in '%s'
MySQL throws Error 1032 with message “Can't find record in 'table'” when it cannot locate the row that matches the index values provided in an UPDATE, DELETE, or replication event. The storage engine scans the index, fails to find the key, and aborts the statement.
The error halts the current transaction and, in replication, stops the replica thread until the inconsistency is resolved.
Treat the issue promptly to restore data integrity and keep replication in sync.
A mismatch between index entries and actual data is the primary cause.
It often happens after an unsafe DELETE, manual data manipulation, or a crash that leaves indexes corrupted.
In replication, the slave executes a statement that references a row deleted or never inserted on the master, producing Error 1032 and stopping SQL THREAD.
First, identify which table and key are involved by reading the full error log.
Then decide whether to repair the index, re-insert the missing row, or resync replication.
Always back up the affected tables before applying any corrective SQL. Use Galaxy’s versioned query history to track every step and roll back if needed.
During UPDATE/DELETE, verify the WHERE clause with a SELECT to be sure the target rows exist.
In replication, use pt-table-checksum or mysqldump to re-sync discrepancies.
After a crash, run CHECK TABLE and REPAIR TABLE on MyISAM, or OPTIMIZE TABLE on InnoDB, to rebuild corrupted indexes and eliminate Error 1032.
Enable binary logging, run transactions atomically, and enforce foreign keys to prevent orphan rows.
Automate nightly CHECKSUMs and monitor the MySQL error log for early signs of key mismatches.
Galaxy helps by storing approved DELETE and UPDATE queries in Collections, ensuring teammates reuse vetted statements instead of ad-hoc commands that risk data loss.
Errors 1033 (ER_BAD_FILE_INFO) and 1062 (ER_DUP_ENTRY) also point to index issues. Unlike Error 1032, they deal with corrupt metadata and duplicate keys, requiring different fixes like repairing frm files or adding UNIQUE constraints.
.
The replica executes DELETE or UPDATE for a row that was already removed on the primary, leading to Error 1032 and a stopped SQL thread.
A sudden power loss or disk error corrupts the index pages, so the key exists in the index but not in the data file.
Rows are deleted outside normal application logic (e.g., direct DELETE without WHERE clause) leaving foreign keys or replication events pointing to non-existent records.
Loading data with FOREIGN_KEY_CHECKS disabled may bypass constraints, causing later updates to fail when the expected parent record is missing.
.
No. The error simply states the row was not found. It may be missing due to legitimate deletes or replication lag, not necessarily corruption.
Skipping one event is acceptable for minor drift, but frequent skips hide deeper data divergence. Prefer full resynchronization.
REPAIR TABLE works only for MyISAM. For InnoDB, use ALTER TABLE ... ENGINE=InnoDB or dump and reload the table.
Galaxy stores vetted DELETE/UPDATE queries, offers version control, and surfaces schema changes, reducing risky ad-hoc statements that create missing keys.
