MySQL Error 1082: Index Mismatch for CREATE INDEX
Description
Error 1082 occurs when MySQL attempts to create an index on a table, but the database cannot find an existing index definition that matches the requirements of the `CREATE INDEX` statement. This often indicates a discrepancy between the table's internal metadata and the expected index structure, prompting the suggestion to recreate the table.
Error Message
Table '%s' has no index like the one used in CREATE INDEX; recreate the table
Known Causes
4 known causesTable Metadata Corruption
Internal inconsistencies or damage within the table's metadata can lead MySQL to misinterpret its existing index definitions.
Direct File Manipulation
Modifying MySQL data files or system tables directly, outside of standard SQL commands, can corrupt index definitions.
Incompatible Index Statement
The `CREATE INDEX` statement might be attempting to create a specialized index that requires a specific underlying index type which is absent or incompatible on the target table.
Incomplete Database Upgrade
An incomplete or failed database upgrade process can leave table metadata in an inconsistent state, affecting subsequent index creation.
