That's obviously not your real code...would be nice to see that as your problem
may elsewhere.
But...
#1 How much memory does your embedded device have AVAILABLE?
#2 Try reducing the cache_size (if #1 is less than 10's of megabytes) --
default cache_size is 1MB which is right around 33*30k -- reduce it to 100k
"pragma cache_size=100"'
#3 Your loop should be more like this:
sqlite3_prepare_v2 ("SELECT id, blobdata FROM Table30KB Where id = rowIndex")
while sqlite3_step()!=SQLITE_DONE
dostuff
end
sqlite3_finalize()

Subject: EXT :[sqlite] SQLITE3 Runs out of memory.
Hi,
Before I start diving into the sqlite3 code, I was wondering if anyone had this
sort of problem before and could possibly point out to me where I might find
the problem.
I am running 3.7.9 on a embedded project using a database with one table
(structured (integer id, blobdata BLOB). Now the id goes from 0 to 61153 and
the blob data is off size 30K roughly.
When I do a loop of the following for every row in the table:
Loop for 61153 records start rowIndex at 0
sqlite3_prepare_v2 ("SELECT id, blobdata FROM Table30KB Where id = rowIndex")
sqlite3_step()
sqlite3_finialize()
End
The code will start to return 7 ( for NOMEM) after requesting the 34th row. Why
would it be running out of memory if I've completed the steps as per the sqlite
website for properly forming prepare, step then finalize?
Regards
Stuart T
