Hello,

I am having the same problem. I define 'tutorial_copy' data sourse on my computer in Control Panel, ODBC data sources.
I was just following steps given in exapmle 'import data in database from MATLAB' in HELP....

> conn = database('tutorial_copy','','')

conn =

Instance: 'tutorial_copy'
UserName: ''
Driver: []
URL: []
Constructor: [1x1 com.mathworks.toolbox.database.databaseConnect]
Message: 'No data found'
Handle: 0
TimeOut: []
AutoCommit: 'off'
Type: 'Database Object'

>> getdatasources

ans =

Columns 1 through 4

'LabVIEW' [1x22 char] [1x20 char] 'dbtoolboxdemo'

Column 5

'tutorial_copy'

>> ping(conn)
??? Error using ==> database.ping
Invalid connection.

where the error is? and what is the solution of it?

Thank you.

Hello,

The problem has been solved. It was my mistake.
Instead of writing 'Data source Name' in --> conn = database('tutorial_copy'*,'','')
i.e. * dbtoolboxdemo, i had written 'tutorial_copy'.

Thank you.
