######### normal test ###############
## test for update clause
merge into targetTable using sourceTable on (targetTable.id = sourceTable.id) when matched then update set targetTable.sales = sourceTable.sales;

## test for insert clause
merge into targetTable t1 using sourceTable t2 on (t1.id = t2.id) when not matched then insert(t1.id, t1.sales) values(t2.id, t2.sales);

######### test condition ###############
## test for match condition

## test for update condition
merge into targetTable t1 using sourceTable t2 on (t1.id = t2.id and t1.id != t2.sales) when matched then update set t1.sales = t2.sales where t1.sales > 1;

## test for delete condition
