How can I create a "dynamic" WHERE clause?
- by TheChange
Hello there,
First: Thanks!
I finished my other project and the big surprise: now everything works as it should :-)
Thanks to some helpful thinkers of SO!
So here I go with the next project.
I'd like to get something like this:
SELECT * FROM tablename WHERE field1=content AND field2=content2 ...
As you noticed this can be a very long where-clause.
tablename is a static property which does not change.
field1, field2 , ... (!) and the contents can change.
So I need an option to build up a SQL statement in PL/SQL within a recursive function.
I dont really know what to search for, so I ask here for links or even a word to search for..
Please dont start to argue about wether the recursive function is really needed or what its disadvanteges - this is not in question ;-)
If you could help me to create something like an SQL-String which will later be able to do a successful SELECT this would be very nice!
Iam able to go through the recursive function and make a longer string each time, but I cannot make an SQL statement from it..
Oh, one additional thing:
I get the fields and contents by a xmlType (xmldom.domdocument etc) I can get the field and the content for example in a clob from the xmltype
