TSQLDBLibraryLoader

TSQLDBLibraryLoader is a Lazarus and FPC component that specifies the names and locations of SQLDB database libraries (DLLs/.sos/.dylibs) should be loaded from where.

Use and alternatives

Recent (end of 2012) FPC versions try to load some default library names, but may fail. Using SQLDBLibraryLoader, you can specify the exact filename to load.

SQLDBLibraryLoader needs to be called before loading/enabling TSQLConnection components.

Note that often you can a similar thing by setting the library name for the TSQLConnection descendant you are using.

Sample code

  SQLDBLibraryLoader1.LibraryName := 'c:\path_to_sqllite_library\sqlite3.dll';
  SQLDBLibraryLoader1.ConnectionType:='SQLite3';
  SQLDBLibraryLoader1.Enabled := true; 
  SQLDBLibraryLoader1.LoadLibrary;
