Hey all i am trying to get a connection to my SQL server version 10.50.2500 in Classic ASP
My code in the .asp page is (including all connection strings I've tried using):
Set objConn = Server.CreateObject("ADODB.Connection")
Set objRS = Server.CreateObject("ADODB.Recordset")
'objConn.ConnectionString = "Provider={SQL Server};Server=xxx.xxx.xxx.xxx\SQLEXPRESS;Database=JForm;User ID=xxxx;Pwd=xxxx"
'objConn.ConnectionString = "Driver={SQL Server};Server=xxx.xxx.xxx.xxx\SQLEXPRESS;Database=JForm;Uid=xxxx;Pwd=xxxx;"
'objConn.ConnectionString = "Provider=SQLNCLI10;Server=xxx.xxx.xxx.xxx,1433;Database=JForm;Uid=xxxx;Pwd=xxxx;Persist Security Info=True"
'objConn.ConnectionString = "Provider=SQLNCLI;Server=.\SQLEXPRESS;Database=JForm;Uid=xxxx;Pwd=xxxx"
objConn.ConnectionString = "Driver={SQL Server Native Client 10.0};Server=xxx.xxx.xxx.xxx\SQLEXPRESS;Database=JForm;Uid=xxxx;Pwd=xxxx"
strSQL = "UPDATE jURLS " & _
"SET rssFeedURL = 'http://www.xxxx.com/rss/" & rss & "'," & _
"csvURL = 'http://www.xxxx.com/csv/" & csv & "'," & _
"jFormName = '" & forname & "'," & _
"isActive = " & active & " " & _
"WHERE jFormName = '" & forname & "'"
objConn.open
objRS.Open strSQL, objConn, 1,3
'If Not objRS.EOF Then
'iterate through records here
'Else
'no records found
'End If
objRS.close
Set objRS=Nothing
objConn.close
Set objConn=Nothing
It seems to crash on the objConn.open. However, it only gives me a 500 - Internal server error. and not an error thats helpful!
Once i take the database code from the page and leave everything else, it works without the 500 - Internal server error being displayed.
What else can i try in order to get this to work?
you have an extra comma here :
"isActive = " & active & "," & _
change it to:
"isActive = " & active & " " & _
about the connection error, try debugging using the connection.errors collection
On Error Resume Next
objConn.open
for each errobj in objConn.Errors
Response.write errobj.Number & "<br />"
Response.write errobj.Description & "<br />"
next
On Error Goto 0
Try:
response.write(strSQL) <-- this will allow you to look at your current SQL statement and see if it makes sense.
set objRS = objConn.execute(strSQL)

I am connecting to a SQL table via an Excel VBA script using using SQL Server vs Windows Authentication as we're creating a generic update application to be used by several different users. If I log into SQL Server Management Studio with the generic ID/pswd and SQL Server Authentication, I can successfully insert and delete rows. When I use the VBA script, I receive an error indicating that the INSERT or DELETE permission was denied. The VBA script works successfully against the same table in a different schema, but fails going against this schema. I am assuming it's something in the SQL environment, as it seems like it's forced to Windows Authentication regardless of how I make the connection. Any help would be greatly appreciated.
Updates:
Thanks for the responses. I hope this additional information helps. We are on SQL Server 15.04102.2, and I am using SQL Server Authentication with a generic application ID and PSWD that has update permissions (my individual windows account only has select permissions)
As I indicated in my initial post, if I execute this code against one test environment, the DELETE and INSERT work perfectly. When I execute it against a different environment, the connection is made, but I get the permissions error on the DELETE and INSERT. If I use the exact same credentials and use SQL Server Authentication to go directly to that environment, I can successfully execute the DELETE and INSERT statements.
Here is the error I receive on the DELETE statement. A similar error is received on the INSERT statement if I bypass the delete for a new add.
Error -2147217911 (The DELETE permission was denied on the object
‘BCG_CGS_DETAILS’, database ‘xxxxxxcustom’, schema ‘dbo’.) in

Ok, this is where I'm at now. the code below works! Yay! However, there are no records in the database to read.

db_username = "my_username"

So with the part above is actually working again. I set out to add a record to the database with the code below. It seems to work as it does not cause an error. However, it is not adding the record though.

This is where I have been stuck. It is not writing to the database. It just runs and nothing gets done. If I remove the resume next portion, it still works with no error but, still, no record being written cause the resume next. I have tried two different users to run the code. Both of which have read and write permission. Now what? I'll just keep trying until someone puts me out of my misery... lol!
Well, it seems a friend and I finally found out what was going on. The code actually works but, for some reason, the database's ID field is not auto-incrementing. So, in order to add a record, we had to first check to see how many records are in the DB then add 1 to the count to use for our new records id. Seems every solution leads to a new issue. That's programing...
Just in case any of that makes sense or even if it doesn't make sense, here the id's properties.

db_name = "my_db-name"

I left all the error checking in there but, it is all commented out. I hope this is the last time I have to come back to this. Goodluck!
I am opening an SQL Server Connection in EXCEL VBA and on the objMyCmd.Execute line when it is using the SQL script I am getting this error message:
"Run-time error '-2147217900 (80040e14)') Automation error"
I have reviewed other SO posts that seem to reference an issue with the connection string itself, but I don't believe that is the issue as I am able to pull the first few variables listed when eliminating the rest of the SQL script.
I have attempted to review the SQL code to see if I am using an incorrect format, or if the language is not written properly and I am not able to determine the issue. I am hoping with some Q & A we may notice something I have missed in how this is written? Please let me know if there is additional information I can provide, below is the code up to the point of error.

In the below code, my second query will not insert into the SQL database, but the first one will update. I can copy the query (from the msgbox i added for testing) and paste it in SQL Server Management Studio, and it will execute fine. I also do not get any error messages back from SQL, though i'm not sure if that code is correct (it was copied + pasted from another source). Also, can i simplify the code to pass both queries at the same time?

The Fill method of the SqlDataAdapter executes the SelectCommand not the UpdateCommand or the InsertCommand. In any case these two commands (and the DeleteCommand) are executed when you call the Update method of the adapter.
Moreover the Update method runs the commands looking for rows changed/added/deleted in the DataTable/DataSet retrieved by the SelectCommand and works only for those rows.
But you don't need an SqlDataAdapter to execute your two queries. You should simply construct an SqlCommand with both texts separated by a semicolon and call ExecuteNonQuery
SqlQuery = "Update MasterVars set Active = 0 where PKEY = #key;" & _
"Insert into MasterVars (Vers, Testing, .....) VALUES (#p1, #o2, ....)"
Using Conn = New SqlConnection("Data Source=SQL01;......")
Using cmd = New SqlCommand(SqlQuery, Conn)
Conn.Open()
cmd.Parameters.Add("#key", SqlDbType.Int).Value = PKEY
cmd.Parameters.Add("#p1", SqlDbType.NVarChar).Value = vers
cmd.Parameters.Add("#p2", SqlDbType.Int).Value = testing
... and so on with other parameters ....
cmd.ExecuteNonQuery()
End Using
End Using
In this incomplete example (too many parameters to write down) I have concatenated the two sql texts in a single string and prepared it with parameter placeholders. Then I build the parameter collection with the exact datatypes required by your table and finally call ExecuteNonQuery to run everything on the database side.
Notice that is not needed to keep global objects like the connection or the command. It is always better to create a local variable, use and destroy it when done. In particular disposable objects like the connection and the command should always created in a Using block
I've got a mission-critical Access 2003 database that changed from a local MDB, to an MDB frontend with the backend on MS SQL Server 2005, using the Microsoft SQL Server Database Migration Assistant (SSMA) software.
Now, I need to permanently change the server that the tables are linked to from an IP address (which is changing soon) to a hostname pointing to the same server. The server itself is not changing, just the connection string.
It's a DSN-less connection, so the ODBC info is contained within the Access MDB file. If I try to refresh the table links within Access, it prompts me for a DSN (which I don't want to use).
I've done some Googling, and I've found several scraps of code to have it update itself each time the program launches. But, I'm worried that that could potentially introduce problems or delays for the users. Is that my best option, or is there some trick to permanently change the connection string stored within the MDB?

You can use VBA to alter the .Connect properties for your linked TableDef s.
See this sample from the Immediate window. (I used Replace() simply to split up that long line.)
? Replace(CurrentDb.TableDefs("remote_table").Connect, ";", ";" & vbCrLf)
ODBC;
DRIVER=SQL Server Native Client 10.0;
SERVER=HP64\SQLEXPRESS;
Trusted_Connection=Yes;
APP=Microsoft Office 2003;
WSID=WIN732B;
DATABASE=testbed;
So I could build a new string with a different SERVER, and assign the new string to the TableDef .Connect property.
If this is intended to be a permanent change you should only need to do it one time, not every time you open the database.
When I've done similar connection changes, it has been between different servers. So I deleted the TableDef and re-created it anew, to make sure Access didn't keep any cached meta information about that connection which would now be out of date. However, in your case, you're dealing with the same physical server, just referencing it by name instead of IP. I doubt the cached information would be a concern for you.
