Hi!
I'm working on a batch of queries and there is a requirement where I have to convert this SQL Server queries to similar-function Oracle.
SQL Server:
Oracle:
Now, the requirement changed that we should have a function that will accept two values: CSV for columns, and CSV of CSV for values (multiple rows). Example:
SomeFunction(
"Directory,ID,Location,UserName,Password,Selector",
"(Directory=Voice Active Directory A,ID=VT-AD1,Location=Canada,UserName=admin,Password=passw0rd,Selector=AD1),(Directory=Voice Active Directory B,ID=VT-AD2,Location=https://beta-proxy.voice.com/VTadp/Proxy/[/url],UserName=admin,Password=passw0rd,Selector=AD2),(Directory=Voice Active Directory C,ID=VT-AD3,Location=https://final-proxy.voice.com/VTadp/Proxy/,UserName=admin,Password=passw0rd)"
The second parameter is a big one as it has all the row data. Also, it has the column names as well because the third row data has a missing selector column value and should be inserted as NULL. The main reason I want to return a resultset indicated by a pointer is that the target table to insert into can be any. It will be the caller's responsibility to send the correct data to the function and handle the returned collection in a loop for the desired table making this function very general. I'll manage that after getting the generic result set. I'll worry about how to navigate that result set once I can actually get it. Can anyone suggest a basic example? Thank you.
