All,
I've been pulling my hair out trying to figure how to use EXISTS. I've had no
luck with it (syntax errors) and I've resorted to this. Is there a
better/recommended way in SQLite to check if a record exists?
static bool IDisDuplicate(string dbFileName, int id)
{
int count;
string connectionString = String.Format("Data Source={0}",
dbFileName);
using (SQLiteConnection connection = new
SQLiteConnection(connectionString))
{
using (SQLiteCommand command = connection.CreateCommand())
{
connection.Open();
command.CommandText =
"SELECT count(1) DatasetID FROM UUT_Info where
DatasetID = " + id + ";";
count = Convert.ToInt32(command.ExecuteScalar());
}
}
if (count > 0)
{
return true;
}
else
{
return false;
}
}
Thanks,
--
