I'm completely new to Visual Basic and I now need to take a program that is entirely constructed in VB6 and add the ability to import a large set of records in bulk from an excel file into the current SQL Database. all of the examples I have found online are confusing and require hard-coding of the file name (ex. Using document As New Spreadsheet() document.LoadFromFile("SimpleReport.xls")) yet this needs to be called by a user anytime they get a new set of records so I need the excel file name to be specified at time of import.
How do I import from excel to SQL using VB6? Can I make a variable for the excel filename or does the string value of the filename have to be hard coded? If I can make a variable can/should I add set and get to it in order to specify the filename? Thanks

I am trying to pass over 37K values in the WHERE clause using IN operator through Excel VBA macro. However, due to resource limitation in Microsoft SQL Server, the query won't execute. I have tried to pass the values in an array in VBA as well as tried creating a list in in SQL. Neither are able to accommodate these many values. Can somebody help? Sharing the code I have tried below.
Dim i as Long
Dim str As String
Dim dict_pn
Set dict_pn = CreateObject("Scripting.Dictionary")
i = 1
With InputS
For i = 1 to 50000
str = Trim(.Cells(i, PN_Col).Value)
dict_pn.Add str, 0
Next
With rsPubs
' Assign the Connection object.
.ActiveConnection = cnPubs
.Open Worksheets("SQL Script").Range("A1") & "('" & Join(dict_pn.keys, "','") & "') " & Worksheets("SQL Script").Range("A2") & "('" & Join(dict_pn.keys, "','") & "') " & Worksheets("SQL Script").Range("A3") & "('" & Join(dict_pn.keys, "','") & "') "
ActiveWorkbook.Worksheets("SQL Results").Range("A3").CopyFromRecordset rsPubs
You should transmit data to SQL Server like in related post
Sub UpdateTable()
Dim cnn As Object
Dim wbkOpen As Workbook
Dim objfl As Variant
Dim rngName As Range
Workbooks.Open "C:\your_path_here\Excel_to_SQL_Server.xls"
Set wbkOpen = ActiveWorkbook
Sheets("Sheet1").Select
Set rngName = Range(Range("A1"), Range("A1").End(xlToLeft).End(xlDown))
rngName.Name = "TempRange"
strFileName = wbkOpen.FullName
Set cnn = CreateObject("ADODB.Connection")
cnn.Open "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & strFileName & ";Extended Properties=""Excel 12.0 Xml;HDR=Yes"";"
nSQL = "INSERT INTO [odbc;Driver={SQL Server};Server=Server_Name;Database=[Your_Database].[dbo].[TBL]]"
nJOIN = " SELECT * from [TempRange]"
cnn.Execute nSQL & nJOIN
MsgBox "Uploaded Successfully"
wbkOpen.Close
Set wbkOpen = Nothing
End Sub
and then you can do any you want - use operator IN or LEFT JOIN whith check for null on SQL server side.
You can use temporary table if you will not close connection - temp table exists only in session level.
This is way from VBA code.
Second way - you can use SSIS package to work with excel files. In package you will have same steps - data frlow to transmit data from excel to server and then run sql code to join data. Or you can use join block inside SSIS package.
Third way that you can implement if data in SQL server less than excel row count limit. You can import data from SQL into Excel sheet, and than use VLOOKUP() function to join tables and find related data.
My task is to add new records from an excel table to a Microsoft SQL Server table, and to do this, I was planning on using ADODB objects; however, my SQL statement is not executing, and I think it has something to do with my connection strings.
In my code, I wrote down the SQL statement that I plan on using in the end, but when I tried:
sql = "SELECT * FROM [Provider=SQLOLEDB;Data Source=hpwfh-ssql01; _
Initial Catalog=HPW DataIntegrated Security=SSPI;Trusted_Connection=Yes].Hubspot_Data"
(a simple select statement) it didn't even work.
Sub update1()
Dim cn, rs As Object, path As String, name As String, sql As String, file As String
path = "T:\Marketing\Data Analytics\Hubspot data for SQL"
name = "Hubspot_Data"
file = path & "\" & name & ".xlsx"
Set cn = CreateObject("ADODB.Connection")
With cn
.Provider = "Microsoft.ACE.OLEDB.12.0"
.connectionstring = "Data Source=" & file & ";Extended Properties=""Excel 12.0 Xml;HDR=YES;Readonly=false;IMEX=0"";"
.Open
End With
sql = "INSERT INTO [Provider=SQLOLEDB;Data Source=hpwfh-ssql01;Initial Catalog=Hubspot_Data;Integrated Security=SSPI;Trusted_Connection=Yes].Hubspot_Data " & _
"SELECT * FROM (SELECT * FROM [Provider=SQLOLEDB;Data Source=hpwfh-ssql01;Initial Catalog=Hubspot_Data;Integrated Security=SSPI;Trusted_Connection=Yes].Hubspot_Data" & _
"EXCEPT SELECT * FROM [hubspot-crm-exports-sql-data-20$])"
Set rs = cn.Execute(sql)
End Sub
Just a side note: the table is named the same thing as the database
For this code, I have gotten three different errors:
The Microsoft Access database engine could not fin the object 'Area' Make
sure the object exists and that you spell its name and the path name
correctly. (And I did not misspell Hubspot_Data)
External table is not in the expected format.
The Microsoft Acess database engine cannot open or write to the file
(My File Path)'\My Documents\Provider=SQLOLEDB.XLSX'. It is already opened
exclusively by another use, or you need permission to view and write its
data.
Clearly the computer is going to the wrong place to retrieve the table it needs, and I have no idea where I went wrong. Thanks for the help.
First of all you need 2 connections - one for SQLSvr and one for Excel.
Then query your source (Excel) and do a separate insert into SQLSvr. You are not going to be able to mix these into one query.
Sub SelectInsert()
Dim cn As Object, rs As Object, sql As String
Dim conSQL As Object, sInsertSQL As String
'---Connecting to the Data Source---
Set cn = CreateObject("ADODB.Connection")
With cn
.Provider = "Microsoft.ACE.OLEDB.12.0"
.ConnectionString = "Data Source=" & ThisWorkbook.Path & "\" & ThisWorkbook.Name & ";" & "Extended Properties=""Excel 12.0 Xml;HDR=YES"";"
.Open
End With
Set conSQL = CreateObject("ADODB.Connection")
With cn
.Provider = "SQLOLEDB"
.ConnectionString = "Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;"
.Open
End With
'---Run the SQL SELECT Query---
sql = "SELECT * FROM [Sheet1$]"
Set rs = cn.Execute(sql)
Do 'the insert. Each rs(n) represents an Excel column.
sInsertSQL = "INSERT INTO table VALUES(" & rs(0) & ";" & rs(1) & ";" & rs(2) & ")"
conSQL.Execute sInsertSQL
rs.MoveNext
Loop Until rs.EOF
'---Clean up---
rs.Close
cn.Close
conSQL.Close
Set cn = Nothing
Set conSQL = Nothing
Set rs = Nothing
End Sub
get properties of your database from "SQL Server Object explorer" and copy the exact same connection string. then copy it to the "appsettings.json" file of your project. It looks like this :
"connectionStrings": {
"ApiDbConnectionString": "Server=(localdb)\\mssqllocaldb;Database=ApiDB;Trusted_Connection=True;"
}
then you need to create an object in your connection string and open a connection to the database using that object, then write your SQL query to the database
Current Situation
I have a database in MSSQL and currently it is able to link to excel the following way.
Excel table which is connected to MSSQL as follows
MSSQL table as below
Currently if I update my MSSQL table, excel table will update accordingly
What I need
I want the vice versa operation. Means whenever I update the excel table, MSSQL also needs to update. Is this possible?
I am able to do it correctly by using following code
Sub updateSqlFromExcel()
Dim cnn As ADODB.connection
Dim uSQL As String
Set cnn = New connection
cnnstr = "Provider=SQLOLEDB; " & _
"Data Source=myServer; " & _
"Initial Catalog=myDatabaseName;" & _
"User ID=username;" & _
"Password=password;" & _
"Trusted_Connection=No"
Set rngName = ActiveCell
cnn.Open cnnstr
excelId = ActiveCell.Value 'This is just an example
excelSeq = ActiveCell.Offset(0, 1).Value 'This is just an example
excelName = ActiveCell.Offset(0, 2).Value 'This is just an example
uSQL = "UPDATE myTableName SET Name = '" & excelName & "', Seq = '" & excelSeq & "' WHERE ID= '" & excelId & "' "
cnn.Execute uSQL
ActiveWorkbook.RefreshAll
MsgBox "Updated successfully. But please wait until background refresh finish before close excel", vbInformation, "Success"
cnn.Close
Set cnn = Nothing
End Sub
Please change myServer, myDatabaseName, username, passwordand myTableNameaccording to your settings in order for this macro to work. Also please add reference library Microsoft ActiveX Data Objects 2.8 Library. In order to add, press Alt+F11 and then goto Tools --> References. Scroll to Microsoft ActiveX Data Objects 2.8 Library and tick the checkbox. Press ok and you are ready to go.
I am struggling with this situation
I have a query that when i run in MSSQL server management studio it gives me 18 rows, it it stored in a cell. The database is connected to a live server and we would like to create Excel dashboards out of them so it get refreshed with live data and create graph etc....
***** EDIT *****
I tried a very simple query and it works i can get for example
select max(datetime)from table and i do have the latest sync.
The thing is: my query has
1) A Declared table for validation
2) A temporary table "with table as( ) ;" that sorts all data and rank them with some filtering "RowNumber" that is called later in with a where statement that take only some row numbers to avoid repeats
I think that in between the connection must close, can it be?
Normally this code works out but for this server i get:
"runtime error 3704 operation is not allowed when the object is closed"
I've searched the forum and the google with no luck
Dim con As ADODB.Connection
Dim rs As ADODB.Recordset
Dim query As String
Set con = New ADODB.Connection
Set rs = New ADODB.Recordset
strCon = "Provider=SQLOLEDB.1;" _
& "Password=*******;" _
& "Persist Security Info=True;" _
& "User ID=********;" _
& "Initial Catalog=*******;" _
& "Data Source=***.**.**.**;" _
& "Use Procedure for Prepare=1;" _
& "Auto Translate=True;Packet Size=4096;" _
& "Use Encryption for Data=False;" _
& "Tag with column collation when possible=False"
con.Open (strCon)
rs.ActiveConnection = Con 'modified with suggestion below
strSQLQuery = Worksheets("Query").Range("B2").Value
rs.Open strSQLQuery
For i = 0 To rs.Fields.Count - 1
Sheet2.Cells(1, i + 1) = rs.Fields(i).Name
Next i
Worksheets("Result").Range("A2").CopyFromRecordset rs
rs.Close
Set rs = Nothing
con.Close
Set cn = Nothing
Can a magician help me out? because now im doing it with excel VBA as a demo but i would like to promote it to a VB tool and want to make sure it is not a server related issue.
Thank you in advance
con.Open (strCon)
rs.ActiveConnection = strCon
should be
con.Open strCon
rs.ActiveConnection = con
ie. you should set ActiveConnection to the Connection object you just opened, not to the connection string.
We are working on changing an existing excel form to deliver a record to our SLQ server.
We have been scuccessful with code that scrubs captures and writes the data to the server using a DSN and ODBC.
scn = dsn=ODBC123
Our target users (of wich there are many) are using excel 2003 and an ODBC connection on each terminal is not practical.
This is my first venture into using ADODB.
I was tripping my badSQL message but do not get an error from the server, until I added the UID and Pass.
Now I am getting
Run-time error '-2147467559(80004005)':
Automation error
Unspecified Error
Would one of you fine ladies and/or gentlemen take a look and provide some guidence?

Exit Sub'
We seem to have both rst and rs as Recordset objects. I don't see a declaration for rst in the supplied code.
In any case, the query string in ssql is run twice. Once when it gets executed and the results (if any) returned into rst. The other time when rs is opened.
You probably only want to run the query string once and, as it seems to be an INSERT-type query, you probably want to use cn.Execute rather than rs.Open
