Let us first retrieve all the table’s records by simply using the following query statement that retrieves all the columns and rows of the table. Let us insert some records in the educba_learning table.Ĭode: INSERT INTO educba_learning (topic_id, subject, sessions, expert_name, charges) VALUES Let us create one table named educba_learning using the following query statement. The advantage of using the aliases is that shorter names can be assigned when the column names are large when multiple tables used in the query using different joins have same-named columns, the aliases of the table can help to determine the column of which table should be retrieved or applied the condition when the aggregated functions and other combinations of the column values operations are performed the retrieved value can be assigned a name instead of the whole expression performed which makes the resultant records read in meaningful and easier way for analysis. Aliases can also be assigned to the table names. Aliases are the alternative names that can be assigned to the values being retrieved from the query statement by specifying different columns and combinations of the columns.
