[sqlite] Are BLOB stored inline with the rest of the record fields?

Thanks for all the details! I was already storing the really large blobs in their own tables. However I will have to review the situations for smallish blobs (about as large as the rest of the fields in a record), as moving them to another table would halve the number of pages involved for

[sqlite] Are BLOB stored inline with the rest of the record fields?

I haven't seen any anyone else mention this yet. Another consideration when working with large blobs is to make those columns that last ones in your schema. To quote Dr. Hipp: "make the BLOB columns the last column in your tables. Or even store the BLOBs in a separate table which only has two

[sqlite] Are BLOB stored inline with the rest of the record fields?

What is the likely max length of a row in your table? if your row length is less than page length-35 then it will fit in to one page. The amount of wasted page depends on what fraction of a page size your typical record is. If you have a record that is 600 bytes long on a DB with 1024 byte page

[sqlite] Are BLOB stored inline with the rest of the record fields?

Hi, I am wondering if very small BLOBs are stored inline with the record fields (in the same page) or in another page? So far I had not worried about it, but now I have a usage case where I need to store 128 and 256 bit integers (numbers, not IDs or hashes), SQLite does not support such large
