SQL Rename Table Index
Renaming IndexesSyntax for changing the name of an index can varies from RDBMS to RDBMS, so check your system manuals for specifics.
ALTER INDEX old_name RENAME TO new_name;
ALTER INDEX Fullname RENAME TO First_Last_Name; ALTER INDEX [ IF EXISTS ] Fullname RENAME TO First_Last_Name; /* ONLY PostgreSQL*/
If the DBMS does not have this alter index option we have to remove the index and recreate it with a new name.
MySQL, SQL server:
DROP INDEX old_name ON table_name; CREATE INDEX new_name ON table_name (column_name1,column_name2,...);
DROP INDEX Fullname ON CUSTOMER ; CREATE INDEX First_Last_Name ON Customer (First_name, Last_Name);
