![]() Whenever we try to do the operations on the views in the MERGE statement, the corresponding reflection of the operations can be seen in the tables associated with the views ass well. We can make use of MERGE statements with tables as well as views. We can make the use of the MERGE statement in DB2 in any of the application programs by embedding it or it can be invocated with the help of dynamic SQL statements which are nothing but the statements that can be executed and are prepared dynamically on the run time depending on the requirement. Further, we can have as many WHEN MATCHED and NOT MATCHED conditions as required for performing different operations as shown above in the syntax by adding …. We can also use views in place of tables for target and source ones. In the above syntax, we have the MERGE INTO clause used for merging the main or target table with respect to changes that are being made to the source or reference table. THEN any operation that you wish to perform on condition being evaluated to true THEN any operation that you want to perform on condition being evaluated to true ON match condition that is specified for matching the records of both the tables USING (table reference which will act as a source table) MERGE INTO name of the table/ name of the view The syntax of the MERGE statement used in DB2 is as shown below – In this article, we will study the syntax of the MERGE statement in DB2 and its implementation with the help of multiple examples demonstrating the usage of the MERGE statement.
