#Sqlite tutorial android
used to perform database operations on android devices such as storing, manipulating or retrieving persistent data from the database. It follows a similar pattern as Retrieve ( -get) but using db. SQLite is an open-source relational database i.e. And when I’m inserting records, the first format in the list will be used to transform my time.Time to a database string. So, that list of priority order formats drives the conversion process.Īs long as my dates strings are in one of these formats, they will get correctly converted when I read them out.
When the above program is executed, it will create the given records in the COMPANY table and will display the following two lines.Func (c *Activities) Retrieve(id int) (api.Activity, error)

When the above program is executed, it will create the COMPANY table in your test.db and it will display the following messages −įollowing PHP program shows how to create records in the COMPANY table created in the above example. If the database is successfully created, then it will display the following message −įollowing PHP program will be used to create a table in the previously created database. You can change your path as per your requirement. Now, let's run the above program to create our database test.db in the current directory. If database does not exist, then it will be created and finally a database object will be returned.

Connect to Databaseįollowing PHP code shows how to connect to an existing database. This routine returns a string that has been properly escaped for safe inclusion in an SQL statement. Public string SQLite3::escapeString ( string $value ) This routine closes a database connection previously opened by a call to SQLite3::open(). This routine returns the number of database rows that were updated, inserted, or deleted by the most recent SQL statement. This routine returns English text describing the most recent failed SQLite request. Public string SQLite3::lastErrorMsg ( void ) This routine returns the numeric result code of the most recent failed SQLite request. Public int SQLite3::lastErrorCode ( void ) This routine executes an SQL query, returning an SQLite3Result object if the query returns results. Public SQLite3Result SQLite3::query ( string $query ) This routine is used to execute a result-less query against a given database. This routine provides a quick, easy way to execute SQL commands provided by sql argument, which can consist of more than one SQL command. The class file is generated in target folder. You can compile the code using the following command: mkdir target javac -cp 'lib/sqlite-jdbc-3.20.0.jar' -d target src/SQLiteJDBCExample.java. The code is located in src and depends on SQLite-JDBC library, located in lib.
Public bool SQLite3::exec ( string $query ) Before running the code, you need to compile the code. By default, open uses SQLITE3_OPEN_READWRITE | SQLITE3_OPEN_CREATE. Optional flags used to determine how to open the SQLite database. If no file by that name exists, then a new database file by that name gets created. If the filename is actual device file name, SQLite3::open() attempts to open the database file by using its value. If the filename is given as ':memory:', SQLite3::open() will create an in-memory database in RAM that lasts only for the duration of the session. If the build includes encryption, then it will attempt to use the key. Public void SQLite3::open ( filename, flags, encryption_key ) 2 Using the SQLdb components with SQLite 2.1 Creating a Database 2.2 Creating user defined collations 2.3 Creating user defined functions 2.4 SQLite3 and Dates 2.4.1 Default values in local time instead of UTC 2.5 SQLDB And SQLite troubleshooting 2. If you are looking for a more sophisticated application, then you can look into PHP official documentation. PHP Interface APIsįollowing are important PHP routines which can suffice your requirement to work with SQLite database from your PHP program.
