## SQLite3 Queries
liblattutil has a SQLite3 abstraction layer. Right now, it only
supports those data types that I myself care about. I'm open to
accepting patches for supporting unimplemented data types.
The sqlite3 APIs also support the logging APIs described above. When
creating a sqlite3 context, you have the option of specifying a
logging context object. Error, info, and debugging messages will be
reported through the logging object.
Sample sqlite3 code:
#include <liblattutil.h>
lattutil_sqlite_query_t *query;
lattutil_sqlite_ctx_t *ctx;
const ucl_object_t *row;
ctx = lattutil_sqlite_ctx_new("/tmp/db.sqlite3", NULL, 0);
if (ctx == NULL) {
query = lattutil_sqlite_prepare(ctx, "SELECT id FROM table WHERE id = ?");
if (query == NULL) {
if (!lattutil_sqlite_bind_int(query, 1, 1234)) {
if (!lattutil_sqlite_exec(query)) {
row = lattutil_sqlite_get_row(query, 0);
printf("ID: %ld\n", lattutil_sqlite_get_column_int(row, 0, 0));
