Is there a 64 bit sqlite3.exe available to avoid out of memory error?

Hi, I'm trying to recover a broken database using the ".recover" feature. I run into a out of memory error while running the command unfortunately.

Is there a workaround for this issue? I thought a 64 bit version of sqlite3.exe may solve the problem as it could allocate more memory.

Any help would be much appreciated.

With either of two readily available C compilers, you can build a 64-bit sqlite3.exe . See Compiling The Command-Line Interface. That executable is much less likely to suffer an OOM failure.

Compiling sqlite yourself gives you maximum configurability, but Nalgeon kindly hosts 64-bit CLI's at https://github.com/nalgeon/sqlite/releases/

and also packages some extensions together at: https://github.com/nalgeon/sqlean

Thanks for the link.

I tried the x64 version... but I still get the same error. The sqlite3 process isn't using more than 6 mb of memory. The broken database has a total size of 142 mb.

So it's probably no real out of memory error.

Agreed. If you want ways to work on this …

Does the .dump command dump any information at all ? Table structure ? Any rows up to the point of corruption ?

Does sqlite3_analyzer.exe tell you anything about the database ?

I don't need to know the answers, but they might tell you something that lets you rescue some of the data.
