SQLite: Programming with SQL functions
Native AccessesAvailable only with this kind of connection
Overview
The use of SQL functions for handling the SQLite data does not require to import the structure of data files into the analysis. However, the data must be handled by queries only. The content of SQLite files cannot be read directly.
Note: Don't forget to read the limitations regarding the use of Native SQLite Connector
Programming

1. Opening the connection

SQLConnect is used to establish a connection to an SQLite database via Native Connector. The type of database used (SQLITE in this case) must be passed in parameter to SQLConnect.
The database name corresponds to the name of the database file
ConnectionNum = SQLConnect("SQLiteDatabase", "sa", "", "", "SQLITE")

2. Running queries

The queries are run by SQLExec. SQLExec expects in parameter the text of the SQL query as well as the name that will be given to this query.
SQLExec("SELECT LASTNAME, FIRSTNAME, EXTENSION, PHOTO FROM CUSTOMER", "QRY1")

3. Retrieving the result

Several methods can be used to retrieve the result:
  • SQLFirst: Used to retrieve the result and to initialize a SQLFirst/SQLCol browse.
  • SQLTable: Used to retrieve the result of the query in a memory table of the WINDEV application or WEBDEV site. The result of the query can be retrieved by partial Fetch.
  • SQLFetch PCS_SANS_TRADUCTION_US: Used to browse the different lines of query result. The browse performed in the query result is a SQLFetch/SQLGetCol browse.
SQLLock is used to lock either the table records, or the records selected by the query.

4. Closing the connection

SQLClose is used to close the connection to the database when all the necessary queries have been run.
