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:
-
The WHERE clause is added to a SQL statement, following the FROM clause. For example: SELECT * FROM Employees WHERE Salary > 50000.
-
The condition specified in the WHERE clause is evaluated for each row in the table.
-
Only the rows where the condition evaluates to true are included in the result set (or affected by an UPDATE or DELETE operation).
So, in summary, the WHERE clause is used to filter rows, not columns. If you want to limit the columns that are returned, you would specify that in the SELECT clause of your statement.
