If any queries remain that have not been finalized, sqlite3_close() will return SQLITE_BUSY with the error message Unable to close due to unfinalized statements.įollowing C code segment shows how to connect to an existing database. All prepared statements associated with the connection should be finalized prior to closing the connection. This routine closes a database connection previously opened by a call to sqlite3_open(). SQLite3_exec() routine parses and executes every command given in the sql argument until it reaches the end of the string or encounters an error. Here, the first argument sqlite3 is an open database object, sqlite_callback is a call back for which data is the 1st argument and errmsg will be returned to capture any error raised by the routine. This routine provides a quick, easy way to execute SQL commands provided by sql argument which can consist of more than one SQL command. Sqlite3_exec(sqlite3*, const char *sql, sqlite_callback, void *data, char **errmsg) If no file by that name exists, sqlite3_open() will open a new database file by that name. If the filename is not NULL, sqlite3_open() attempts to open the database file by using its value. If the filename argument is NULL or ':memory:', sqlite3_open() will create an in-memory database in RAM that lasts only for the duration of the session. This routine opens a connection to an SQLite database file and returns a database connection object to be used by other SQLite routines. Sqlite3_open(const char *filename, sqlite3 **ppDb) If you are looking for a more sophisticated application, then you can look into SQLite official documentation. C/C++ Interface APIsįollowing are important C/C++ SQLite interface routines, which can suffice your requirement to work with SQLite database from your C/C++ program. You can check SQLite Installation chapter to understand the installation process. Installationīefore you start using SQLite in our C/C++ programs, you need to make sure that you have SQLite library set up on the machine. In summary, I hope these SQLite CREATE TABLE and INSERT statement examples are helpful.In this chapter, you will learn how to use SQLite in C/C++ programs. INSERT INTO order_items VALUES (null, 2, 1, 10) INSERT INTO order_items VALUES (null, 2, 3, 6) INSERT INTO order_items VALUES (null, 1, 2, 8) INSERT INTO order_items VALUES (null, 1, 1, 5) INSERT INTO customers VALUES (null, 'FOOBAR', '200 Foo Way', 'Louisville', 'KY', '40207') INSERT INTO customers VALUES (null, 'ACME, INC.', '101 Main Street', 'Anchorage', 'AK', '99501') INSERT INTO salespeople VALUES (null, 'Barney', 'Rubble', 10.0) INSERT INTO salespeople VALUES (null, 'Fred', 'Flinstone', 10.0) INSERT INTO coffees VALUES (null, 'French_Roast_Decaf', 9.99) INSERT INTO coffees VALUES (null, 'Colombian_Decaf', 8.99) INSERT INTO coffees VALUES (null, 'Espresso', 9.99) INSERT INTO coffees VALUES (null, 'French_Roast', 8.99) INSERT INTO coffees VALUES (null, 'Colombian', 7.99) SQLite INSERT statement examplesīesides seeing those SQLite CREATE TABLE examples, if you'd also like to see some SQLite INSERT examples, these SQLite INSERT statements all work with the SQLite create table statements shown above: I created these database tables specifically for SQLite examples, and as a result I tried to include a variety of SQLite data types in the CREATE TABLE examples (even though SQLite doesn’t care much about those data types). * order_items (multiline comment example)įOREIGN KEY(order_id) REFERENCES orders(id),įOREIGN KEY(product_id) REFERENCES products(id) * Released under the Creative Commons License.įOREIGN KEY(customer_id) REFERENCES customers(id),įOREIGN KEY(salesperson_id) REFERENCES salespeople(id) Sure, here’s a small collection of SQLite CREATE TABLE examples I recently created for my other SQLite tutorials: SQLite database FAQ: Can you show me an example of the SQLite CREATE TABLE and INSERT syntax?
