Ik wil 300.000 records exporteren naar een csv-file.
In het verleden kon dit in 1 uur nu kan dit gemakkelijk 8 uren duren.
Heeft dit iets te maken met de versie/instellingen van SQL vroeger sql-navigator 4 nu sql-navigator 5 .
Of heeft dit iets te maken met het netwerk?
Het gaat vooral over de snelheid van de "fetching".
Aan de te exporteren records is er niets gewijzigd.


I want to export data to a CSV-file.
In the past the export of 300.000 records took 1 hour now it takes 8 hours or more.
Does the version of sql-navigator has anything to do with that or a setting, or can it be the network? In the past we used SQL Navigator 4 now we are working with SQL Navigator 5.
The records didn't change.

It's the same query on the same data?
Are there any indexes involved? If yes, did you analyze your tables lately?

[Edit: ah, sorry, the records didn't change]

The query hasn't changed.
The query gives result in 15 min. But it is the exporting of the data that takes forever.
