Re: Reading from an Excel table into an Oracle table or list to use in a query

short answer? you can't, at least not easily. longish answer, of course you can :-P the question is how.

You could create a CSV off the excel file and then use it as an external table. This requires DBA intervention.
You can create a CSV and then use sql*loader (which is included in the standard client and has an instant client version). This requires no DBA privileges, but does require that there's a table where the data is going to be loaded.
You could also deploy (could you?) APEX, which has a facility to load a table from an excel file. But this requires privileged access to the database.
You could potentially use the excel function "CONCATENATE" to generate the insert statements and then run that script from SQL*Plus/Developer. This is by no means performant, but it's easy to do, especially if there is a single table involved.

I suggest you add some indexes afterwards to speed up your queries. Basically, index the columns through which you will filter in the where clause.

a quick google search returned this. I have not tested it, but it looks plausible.

I hope this helps.
