Question

I have a dump of several Postgresql Tables in a selfcontained CSV file which I want to import into an Oracle Database with a matching schema. I found several posts on how to distribute data from one CSV “table” to multiple Oracle tables, but my problem is several DIFFERENT CVS “tables” in the same file.

Is it possible to specify table separators or somehow mark new tables in an SQLLDR control file, or do I have to split up the file manually before feeding it to SQLLDR?

Answer 1

That depends on your data. How do you determine which table a row is destined for? If you can determine which table base on data in the row, then it is fairly easy to do with a WHEN.

LOAD DATA
  INFILE bunchotables.dat
INTO TABLE foo WHEN somecol = 'pick me, pick me' (
  ...column defs...
)
INTO TABLE bar WHEN somecol = 'leave me alone' (
  ... column defs
)

If you’ve got some sort of header row that determines the target table then you are going to have to split it before hand with another utility.
