The last step of the guide is to create an SQLite database:
Create a database using GUI and create a test table at will. A separate file with. s3db as the end is displayed.
Once system. Data. SQLite. dll is referenced as part of a. Net project, it can be used as easily as writing using system. Data. SQLite at the top of your application. By using the ADO. Net packaging layer, a parameterized query looks like this:
string lookupValue;using (SQLiteCommand cmd = cnn.CreateCommand()){ for (
parameterized query looks like this:
String lookupvalue;Using (sqlitecommand cmd = CNN. createcommand ()){For (INT I = 0; I {Lookupvalue = getsomelookupvalue (I );Cmd. commandtext = @ "Update [Foo] Set [value] = [value] + 1Where [Customer] Like '"+ lookupvalue + "'";Cmd. executenonquery ();}}
