This design choice makes it highly efficient but also poses challenges when attempting to trace or log SQL queries executed by an external application, especially when the source code of that application…
Storing and Retrieving Binary Data in SQLite Using BLOBs When working with SQLite in a C program, one common requirement is the storage and retrieval of binary data, such as images, using Binary Large Objects (BLOBs). BLOBs allow for the storage of raw binary data directly within the database, which can be particularly useful for…
Memory Leak Observed During Repeated sqlite3_exec() Calls When using SQLite3 in an embedded Linux environment, a memory leak can manifest during repeated calls to the sqlite3_exec() function.
