I ran across a sample Excel VB macro that Ken wrote that connects to a local Access database and inserts the rows of excel data into the Access table. It works perfectly, except i need to connect to a remote Pervasive SQL database. I have had success doing some ODBC connections using the connection wizard . These were just Select statement queries, i need to be able to connect to my remote pervasive database and insert rows of data . i tried recording a macro so i could look at the connection string but have had no luck getting the string to work in VB. I am thinking that the Insert code would have to be adjusted to work with Pervasive. I supplied Ken's code below Thanks for any help that can be offered.

IP address of pervasive server: 192.168.1.70

Name of pervasive database: globalHII




Here is Kens Code:

Not tried it myself, but wouldn't this be a better connection


cnt.Open "Provider=PervasiveOLEDB;" & _
"Data Source=" & dbPath & ";"

Just for clarification, Tommy is trying to convert this article (http://www.excelguru.ca/node/18) to Pervasive SQL.

I haven't ever used pervasive, but being that the routine uses ADO to inject the records, I would assume that only the change of connection string to what Bob supplied would be sufficient.

Let us know if that does/doesn't work, Tommy. :)

i think i may be making progress ... i am not getting an error with the connection screen .Here is what i am using

cnt.Open "Provider=PervasiveOLEDB;Data Source=demodata;Location=" & dbPath & ";"

i am getting errors on the insert , i think it is because pervasive syntax is different than Access

right now i would like to see if i am even connecting with the databse at all. I would like to cut the code down right now so that it will do a Select statement .

Select * From Import

i can get the select statement into the code i am having trouble assiging it to a cell start displaying the results too. any ideas ?

Thanks for the replies and help so far

if this helps any for the problem with the insert command


this is a pervasive SQL Insert command

Insert INTO Import(Hours,Major,Minor,gpa) VALUES(33,'pe','music',4.0);

Ken and bob thanks so much for the help and code. With a few tweaks this code works with a Pervasive Database. Maybe this can will help somebody else. Thanks again guys :)

Hi Tommy,

Sorry, been out all day and not able to get back. Glad you got it sorted out. :)

PS... really? The connection string refers to PervasiveOLEDB. (with the period?) That seems odd to me...

Me too Tommy, we are some hours ahead and when you posted last night I was drinking, then it was bed whilst you were still grappling :) I see the INSERT syntax is the same for Pervasive as (most?) other dbs.

Ken, the period is not required after OLEDB in the connect string. just a typo, glad you caught that .

Ken Puls

No worries. I edited the code to remove the extra period.
