| Hi, Please tell me whether every rowdata of a table has any uniqueID or any number. Means if I retrieve some data through select statement then can I know the correponding Unique identifier value for a particular row depending on the indexing e.g. row 2 has Unique identifier value as 2 according to the indexing. |

| If u have a primary key constraint or unique key constraint defined on any column in a table then that column will have unique value for every row data |
