Using EXISTS in Oracle SQL Queries Practically, it can be done in multiple ways with varying performance stats and scope of extension. The Oracle EXISTS operator can suitably fit into such scenarios which require the check for existence of a parent query record in a subquery. Example Code [1] achieves it with the use of EXISTS operator. Example Code [1]

SQL Integrity Constraints The constraints available in SQL are Foreign Key, Not Null, Unique, Check. Constraints can be defined in two ways. 1) The constraints can be specified immediately after the column definition. This is called column-level definition. 2) The constraints can be specified after all the columns are defined.

SQL WHERE Clause So SQL offers a feature called WHERE clause, which we can use to restrict the data that is retrieved. The condition you provide in the WHERE clause filters the rows retrieved from the table and gives you only those rows which you expected to see. WHERE clause can be used along with SELECT, DELETE, UPDATE statements.

To create a multiple IF statement, replace the value returned if the condition is evaluated to false in the first statement by a second IF statement, enclosed in its own set of parentheses.

Visual Basic for Applications Reference You can have as many ElseIf clauses as you want in a block If, but none can appear after an Else clause. Block If statements can be nested; that is, contained within one another. When executing a block If (second syntax), condition is tested. If condition is True, the statements following Then are executed. If condition is False, each ElseIf condition (if any) is evaluated in turn. When a True condition is found, the statements immediately following the associated Then are executed. If none of the ElseIf conditions are True (or if there are no ElseIf clauses), the statements following Else are executed.
