We have code to read some tables from QuickBooks. The connection is Open though
ADODB.Connection cn = new ADODB.Connection();
try
{
String connStr = "Driver={QODBC Driver for QuickBooks};
DFQ=\\Vaquick01\qbcf\Production\Network Solutions - Manual Billing Production.QBW;OpenMode=M;OLE DB Services=-2";
cn.Open(connStr, null, null, 0);
}
And the read statement is
rs.Open("Select * from " + sourceTableNames[i] + " NOSYNC", sourceConn, ADODB.CursorTypeEnum.adOpenStatic, ADODB.LockTypeEnum.adLockOptimistic, 0);
The connection is open fine. Our problem is on read statement. If we don’t add "NOSYNC" we have very bad performance issue and one specific process might run for more than 6-7 hours. The read statement is running for couple hours without getting any data back. After we add "NOSYNC" the performance issue seems gone but we got inconsistent data with Quickbook. Sometimes the last couple days data are missing. It may or may not get refreshed in next day run. The whole process does not have any exception thrown.
