How to query the unique index of a table in Oracle?
In Oracle, you can use the following SQL statement to query a table’s unique index:
SELECT index_name, table_name
FROM all_indexes
WHERE uniqueness = 'UNIQUE'
AND table_name = 'your_table_name';
Please replace ‘your_table_name’ with the name of the table you want to query. This SQL statement will return the names of all unique indexes in the specified table and their corresponding table names. If there are multiple unique indexes in the table, each unique index will be returned as a separate result.
