sqlite Executing a Statement


A statement is constructed with a function such as sqlite3_prepare_v2().

A prepared statement object must be cleaned up with sqlite3_finalize(). Do not forget this in case of an error.

If parameters are used, set their values with the sqlite3_bind_xxx() functions.

The actual execution happens when sqlite3_step() is called.

const char *sql = "INSERT INTO MyTable(ID, Name) VALUES (?, ?)";
sqlite3_stmt *stmt;
int err;

err = sqlite3_prepare_v2(db, sql, -1, &stmt, NULL);
if (err != SQLITE_OK) {
    printf("prepare failed: %s\n", sqlite3_errmsg(db));
    return /* failure */;

sqlite3_bind_int (stmt, 1, 42);                          /* ID */
sqlite3_bind_text(stmt, 2, "Bob", -1, SQLITE_TRANSIENT); /* name */

err = sqlite3_step(stmt);
if (err != SQLITE_DONE) {
    printf("execution failed: %s\n", sqlite3_errmsg(db));
    return /* failure */;

return /* success */;
