Database Question

Solved!
Go to solution

Hello All!

I'm trying to read some data from a big data file and I'm using one of the example from the package called "Read All Data". When I run the VI and click Get Data button, it shows the column value but get an error that says ran out of memory. I think this example is great because it reads no problem when the file is small. Is there a way around that I can just pull todays date data or data that has been processed in particular date?

 

Thanks in advance.

You can wire an optional clause to reduce data, it uses standard SQL querries try using a WHERE caluse

ie 'WHERE Date >... and <...' you can limit the returned data.
