Home -> Community -> Mailing Lists -> Oracle-L -> Two scenarios, pl/SQL
I have a database, with some table relationed to each other, I would like to have 2 scenarious,
Case 1: I have 4 tables, table1, table 2, table 3 and table4 included in a join, this
query should run in the most common query.
In table 1 and in table 2 exist a relation, id_nr in table1 and id_nt in table2, when
they match each other, then this query should run. So if id_nr in table1 also exists
in table2, then the query should run
.
But if it isnt so then case2 should run instead.
Case 2: If the first condition is not valid (which means that id_nr in table1 and id_nr doesnt match each other) then another query would run, which include the same tables also includes another table .
How can I handle these case? Should I first create 2 views of the tables joined inthe
queries and then one procedure which runs query1 and another procedure which runs
query 2.
Please give me a pl/SQL example on how to handle this. Also include the matching
condition between table1 and table 2 in case1.
Would appreciate if someone could give me some good example.
