hi,

i have a win7 pc 64bit, and i have an application that makes connection to mySQL database using ODBC connector. I've installed mysql-connector-odbc-5.1.11-winx64 driver. whenever the application trying to connect an error appears:

-2147467259 from microsoft ole db provider for odbc drivers:[microsoft][odbc driver manager] data source name not found and no default driver specified

after i installed mysql-connector-odbc-5.1.8-winx64 driver, the problem solved.

can any one tell me a reasonable explanation for this issue?

Thank You.

the code:

VB

Public connSQL As New ADODB.Connection
connSQL.ConnectionString = "driver=MySQL ODBC 5.1 Driver;database=" + sDBName + ";server=" + sServerNM + ";uid=" + sUID + ";pwd=" + sUPwd
connSQL.Open()

Your connection string is VERY wrong. Take a look at this list[^] on ConnectionStrings.com to see which one best fits your situation.

BTW: The curly brackets are there for a reason. Do NOT leave them out!
