示例1: TestChangesCount
public void TestChangesCount()
{
var initialChangesCount = 0;
var insertChangesCount = 0;
var numRecords = this.rnd.Next(1, 11);
var insertedRecords = new List<Tuple<int, long, string, double>>(numRecords);
for (var i = 0; i < numRecords; i++)
{
insertedRecords.Add(new Tuple<int, long, string, double>(i, this.GetRandomInteger(), this.GetRandomString(), this.GetRandomReal()));
}
using (var connection = new SQLiteConnection(this.databaseRelativePath))
{
using (var statement = connection.Prepare("DROP TABLE IF EXISTS TestQuery;"))
{
statement.Step();
}
using (var statement = connection.Prepare("CREATE TABLE TestQuery(id INTEGER, i INTEGER, t TEXT, r REAL);"))
{
statement.Step();
}
initialChangesCount = connection.ChangesCount();
foreach (var record in insertedRecords)
