#59580) When restoring a view to a different database, the current implementation incorrectly replaces **all** database names in the view definition with the target database name. This breaks cross-database references. **Example:** - Original: `view_db` has a view referencing tables from both `base_db` and `view_db` ```sql SELECT * FROM `internal`.`base_db`.`table1` JOIN `internal`.`view_db`.`table2` ``` - After restore to `restore_db` (BEFORE this PR): ```sql SELECT * FROM `internal`.`restore_db`.`table1` -- ❌ Wrong! Should be base_db JOIN `internal`.`restore_db`.`table2` -- ✅ Correct ``` - After restore to `restore_db` (AFTER this PR): ```sql SELECT * FROM `internal`.`base_db`.`table1` -- ✅ Correct! Preserved JOIN `internal`.`restore_db`.`table2` -- ✅ Correct ``` **Root Cause:** The regex pattern `(?<=\`internal\`\\.\`)([^\`]+)(?=\`\\.\`)` matches **any** database name, not just the source database name.
