Question
The Oracle WHERE clause: A.Limits the column data that are returned.B.Limits the row data are returned.
Solution
The Oracle WHERE clause limits the row data that are returned. This clause is used to filter the results of a SELECT, UPDATE, or DELETE statement. Here's how it works:
-
First, you specify the SELECT statement to choose the table and columns from which you want to get data. For example: SELECT * FROM Employees. This would select all data from the Employees table.
-
Then, you add the WHERE clause to this statement to filter the rows that you want to return. For example: SELECT * FROM Employees WHERE Salary > 50000. This would select only the rows from the Employees table where the Salary is greater than 50000.
So, the WHERE clause doesn't limit the column data that are returned. It limits the row data that are returned based on the condition you specify.
