Well, because of using sql client you can not use the oledb provider
try using this connection string :

workstation id=your_compute r_name;packet size=4096;user id=v-tleung;data
source=your_sql _server;persist security info=False;init ial catalog=Pubs;
Password=Myname is@01;

if your sql server is installed locally for data source put : localhost

you can see here all of possible connection strings :
http://www.connectionstrings.com/

Dear Martin,

It works!!

After I used the following connection string:

¡°workstation id='sha-tongl-xp1';uid=sa;pwd ='';server=loca lhost;initial
catalog='Pubs'¡ ±

I really appreciated your help. Have a wonderful day!
