i can create a new mysql db manually with an name having an underscore in it but cannot create it programatically .. see below with the code

   Set cnnado = New adodb.Connection
   strCon = "DRIVER={MySQL ODBC 3.51 Driver};SERVER=192.168.1.64;"
   strCon = strCon & "DATABASE=mysql; UID=xxxx;PWD=yyyyy;OPTION=3"
   cnnado.ConnectionString = strCon
   cnnado.Open
   strExecute = "CREATE DATABASE " & "aaaa_1"
   cnnado.Execute strExecute

This code works fine for a db name 'aaaa1' but nout for 'aaaa_1' .. i can create the db manually ok eg via the command prompt and mysql or using something like sqlyog.

The underscore is a special character so to use it you've got to escape it or user the chr(242)
E.g.
strExecute = "CREATE DATABASE " & "aaaa" & chr(242) & "1"

does it work if the database is enclosed in square brackets?
Example:
strExecute = "CREATE DATABASE " & "[aaaa_1]"

Open in new window

I don't see why it would not accept the underscore:
http://dev.mysql.com/doc/refman/5.0/en/identifiers.html

anyhow, for MySQL that would be backticks:
strExecute = "CREATE DATABASE " & "`aaaa_1`"

To clarify my comment above, I'm referring to vb syntax where the underscore is used for continuation of code on new lines and may be being interpreted incorrectly in this case

Are you sure you allocated the points right here?
If the back ticks solved your issue then the points should go to angeliii along with an A grade
