Hello All, I am accessing a large indexed text dataset using sphinxse via MySQL. The size of resultset is on the order of gigabytes.

Data so...
When using JDBC and accessing primitive types via a result set, is there a more elegant way to deal with the null/0 than the following: int myInt = rs.getInt(columnNumber) if(rs.wasNull())? { // Treat as null } else { // Treat as 0 } I personally cringe whenever I see this sort of code. I fail to see why ResultSet was not defined to...

In some languages (ColdFusion comes to mind), you can run a query on the result set from a previous query. Is it possible to do something like that in php (with MySQL as the database)?

I am trying to merge records from an Oracle database table to my local SQL table. I have a variable for the package that is an Object, called OWell. I have a data flow task that gets the Oracle data as a SQL statment (select well_id, well_name from OWell order by Well_ID), and then a conversion task to convert well_id from a DT_STR o...
Does anyone know if there's a good general-purpose Table-based structure that I can use for manipulating data? ResultSet is an interface, so am I stuck having to fully implement something if I want similar functionality without a database?

Hi, I have to read in a large record set, process it, then write it out to a flat file. The large result set comes from a Stored Proc in SQL 2000.
