Connection to a remote pervasive databse

[tommyt61]

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 & ";"

[Ken Puls]

Just for clarification, Tommy is trying to convert this article 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.

[tommyt61]

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

[tommyt61]

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);

[tommyt61]

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...

[Bob Phillips]

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.

[tommyt61]

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.
