Re: Out of memory issue during INSERT

Hey there,

 

just for a second think of what you are asking here:

  1. please create the join result of the 4 tables (you say this will deliver 10000000 records) and probably you're right as you just do cross joins (any use case for that or just playing around?)
  2. take the result set above, read it and insert the first 10000 into a table.

 

Now, take a wild guess, where your memory (how much do you have btw) will be spend?

 

You might rethink your join conditions here or go for a larger machine.

Unlike other DBMS SAP HANA will never spill out data to disk in order to process requests that are too large.
