Pocket Database Connection Query Guide Keywords: Access, SQL Server, Oracle, ASP, ADO Pocket Database Connection Query Manual Preface: National Day, add recently, some netizens do not want to write some experience, I have to put me usually Some of the materials collected by some databases are used to take out some of the information to give everyone a holiday gift. The following information may not be too complete, but can be used to do usual information query, I hope to help everyone, huh, huh. Here will briefly introduce several ADO connection: ODBC DSN, ODBC DSN-LESS, OLE DB Provider, and "MS Remote" Provider.1. ODBC DSN connection i.dsnoconn.open "DSN = Advworks;" & _ "uid = admin;" & _ "PWD =;" Note: You cannot use this way from MDAC2.1, that is, only DSN File Name In ConnectString, you must use the DSN, UID, and PWD flags at the same time. For example, the following manner will be wrong in MDAC 2.1: Oconn.open "II.File DSnoconn.open" filedsn = / somepath / mydb.dsn; "& _" uid =; " Iii.odbc DSN-Less ConnectionsA) odbc text driveroconn.open _ "Driver = {Microsoft text driver (* .txt; * .csv)};" & _ "dbq = / somepath /;" & _ "extensions = ASC, CSV, Tab, Txt; "& _" PERSIST Security Info = FALSE "Note: You need to specify the file name used in the SQL statement.
For example: ors.open "Select * from customer.cs.csv", _oconn, adopenstatic, adlickread, adopenly, adptextb) odbc driver for accessi) Ordinary security mode: Oconn.open _ "driver = {Microsoft Access Driver (* .mdb)};" & _ "DBQ = / somepath / mydb.mdb;" & _ "uid = admin;" & _ "PWD =;" II) If you use System Database: Oconn.open _ "Driver = {Microsoft Access Driver (*.
