Excel (MAC) to SQL Server connection using macro - sql-server

I have a macro enabled Excel sheet in MAC where I have some data and want to export it to SQL Server. I am trying to truncate the target table first and then insert but my code is not working. The code needs to be working across both MAC and Windows. Please help.

Excel VBA ADO recordset issue with Null values

I'm pretty new at VBA and having an issue with ADO.
Currently the code im using returns fields (Name, Suburb, State) from a SQL database into a ListBox.
The code works fine as long as there are there all fields have a value, if there is a Null value it returns the error
Could not set the List property. Type mismatch
I need to find a way so if the Suburb and/or State fields return a Null value that it still populates the Listbox.
Any info would be greatly appreciated, thanks in advance!

How do I write to SQL table using excel VBA

I have a SQL table called Audit. There are two fields in this table called UN and CN. My server name is analive and DB is DW_ALL. I am trying to capture in excel the username and computer name that accesses/opens my workbook or sheet then write that audit information to my SQL table.
Sub UpdateTable()
Dim cnn As ADODB.Connection
Dim uSQL As String
Dim strText As String
Dim strDate As Date
strText = ActiveSheet.Range("b4").Value
''strDate = Format(ActiveSheet.Range("c4").Value, "dd/mm/yyyy")''
Set cnn = New Connection
cnnstr = "Provider=SQLOLEDB; " & _
"Data Source=icl-analive; " & _
"Initial Catalog=DW_ALL;" & _
"User ID=ccataldo;" & _
"Trusted_Connection=Yes;"
cnn.Open cnnstr
''uSQL = "INSERT INTO tbl_ExcelUpdate (CellText,CellDate) VALUES ('" & strText & "', " & strDate & ")"''
''uSQL = "INSERT INTO Audit (UN,CN) VALUES (MsgBox Environ("username"), MsgBox Environ("username""''
uSQL = INSERT INTO Audit (UN,CN) VALUES ('MsgBox Environ("username") ', 'MsgBox Environ("username"'))
Debug.Print uSQL
cnn.Execute uSQL
cnn.Close
Set cnn = Nothing
Exit Sub
End Sub
Connection strings can be tricky things. I rely heavily on ConnectionStrings.com to refresh my memory.
Trusted_Connection and User ID are mutually exclusive. Use trusted connection when you want to log onto SQL Server using your Windows account. Username and password are for logging in with a SQL account.
Assuming you want to use your Windows login; try this:
Provider=SQLNCLI11;Server=analive;Database=DW_ALL;Trusted_Connection=yes;
Here is a sample script that writes to an AccessDB. The SQL Should be similar as well as the needed vba statements. I hope it helps

"Application Defined or Object Defined" error in VBA-SQL connection

I am trying to write an Exce-Vba code for SQL connection. The code, first will open the connection to the server, then it will copy a 4 columns of table (Range("C22:G81")) from my Excel-sheet to the SQL-server (I am only trying to send numerical table now as a test, I don't send any column name)
I have been trying to solve a "Application Defined or Object Defined" error quite long time. I get the error for the connection string strCon = "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" & strName & ";Extended Properties=""Excel 12.0;"
I even tried with another version with password option like strCon = "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" & strName & ";Extended Properties=""Excel 12.0; Jet OLEDB:Database Password='passwd';"
But I get the same error. I am quite new in SQL-coding. I wonder if I am missing something important.
Lasly, I don't know if it is related to this error, but I manually created 4 columns in the SQL server for my 4 columns in the Excel. Do I need to write something specific that those 4 columns in the Excel-sheet will find the right columns in the SQL-server?
Thanks in advance...

End Sub
After getting the same error for the "connection string", I changed the strategy, and I used dbclass procedure to open a connection. So the new code is like below. (I found this coding from a guy, but he is on vacation now, so I can't ask him).
It gets connection (dbclass) properties automatically, which are saved in the main ThisWorkbook. This code doesn't give any error at all, but it doesn't copy the column from the Excel to the database. I tried different versions for the sql-query, like SQL = .... VALUES('result') or SQL = .... VALUES(result), but there is no result again, without error.
Private Sub Testing_Click()
Dim FindColValues() As Double
Dim ValidBook As Workbook
Dim ValidSheet As Worksheet
Dim DataRange As Range
Dim dataa As Range
Application.ScreenUpdating = False
TheSheet = "Sheet2"
Set ValidSheet = Worksheets(TheSheet)
Set DataRange = ValidSheet.Range("C21:C81")
' Below creating an array "result(it)" from the seleced range.
For Each dataa In DataRange
ReDim Preserve result(it)
result(it) = dataa.Value
it = it + 1
Next
' Below is just an alternative array for "in case"
arrData = ValidSheet.Range("C22:G81").Value
SQL = "INSERT INTO Table_test (Column1) VALUES ('result()');"
dbclass.ExecuteSQL SQL
End Sub
Below is dbclass connection properties which is read automatically by the other function:
Private Sub Workbook_Open()
Dim connOk As Boolean
Dim rs As New ADODB.Recordset
Dim MyWorkBook As Workbook
Dim CurSheet As Worksheet
Set dbclass = New clsDB
dbclass.Database = "Tables"
dbclass.ConnectionType = SqlServer
dbclass.DataSource = "E45c7642"
dbclass.UserId = Application.UserName
connOk = dbclass.OpenConnection(False, True)
If connOk = False Then
MsgBox "Cannot connect"
Else
MsgBox "The server is connected"
End If
End Sub
Finally I found the problem for my second code. As I wrote before, in my alternative code (second code), I didn't get any error at all in VBA, but it didn't save my table into the server.
Now I know the reason, because my real value was in "comma" format, but the server saved the value in "dot" format. So I added Str(value) to convert the "comma" value to the "dot" value, and it works now:
....
SQL = "INSERT INTO Table_test (Column1) VALUES (" & Str(result(1)) & ")"
dbclass.ExecuteSQL SQL
End Sub

Deleting Records in SQL server table prior to insert

I have a excel workbook that is a project plan template, that the PM fills in information and it gets loaded into a sql database. Currently the process if via a batch process that loads two tables(1 with 1 row of data and the other with multiple records). I am changing it to be a direct insert from excel into sql server via vba. I have the insert working but each table has a project id column which is the PK. The pm may update and save this file multiple times. The tables get updated with the most recent save information. I have solved this by adding a delete statement into my code and then inserting the updated record. This works great for the table with 1 record but I can't get the table with multiple records to work. It deletes the records and goes through the first loop of the insert but then goes back to the delete and removes the records.
I have attached the code for the multiple table delete and insert. Can someone tell me what I am doing wrong?

It's difficult to be sure without seeing the data that you're trying to save, but I suspect you have a logic error.
The value for rowData is built up dynamically in a loop. which is correct.
rowData = wks_BackgroundData.Range("A" & iRowNo & ":AV" & iRowNo).value
but the values for compare and value are always read from the same location inside the loop. So the delete statement will be executed over and over again.
compare = wks_BackgroundData.Range("AV2").value
value = wks_BackgroundData.Range("BA2").value
Should compare and value not also be read dynamically?
compare = wks_BackgroundData.Range("AV" & iRowNo).value
value = wks_BackgroundData.Range("BA" & iRowNo).value
Or
you should move the delete statement outside of the loop, to ensure that it's only executed once
Or
you should keep a flag that will indicate that the delete has already been executed, and not execute it again.
hasExecuted = false <- OUTSIDE THE LOOP
...
...
If compare = value and hasExecuted = false Then
sql = "delete from dbo.STAR_DC_INITIAL_ProjectDetails_ExcelDevCopy where proj_id = " & value
conn.Execute sql
hasExecuted = true
...
...
Also, I don't think you should have a IF x=y THEN delete ELSE INSERT. Should it not be IF x=y THEN delete, and always INSERT. With the else, it will only insert if the record didn't exist, but if it deleted the record, it will never insert the new one.
Hope that helps a bit
Avoid using VBA for new development work. If you need to constantly take this Excel document and insert it into a SQL Server database, then use SSIS and some C# to easily make it a scheduled task via the SQL Agent, or simply do as the screen shot below suggests, which is a no-code and easily configurable import of flat files / database tables into SQL Server. Lastly, from a usability standpoint, There are many better methods to track Excel sheets or forms data (SharePoint, Excel 2013, Access, cloud/on premise drives) or using an internal WordPress distribution with some plugins like WP-document revisions.
As noted above I used Spock addition of dynamic lookup of values for the compare and value variable. Once I did that I added the hasExecuted flag.

How to load csv files from the internet into an Access database?

I have the following array that contains ticker symbols: Public Shared tickerArray() As String = {"GOOG", "AAPL", "V", "MSFT"}. I need to use this loop: For Each tickerValue In Form1.tickerArray to load the csv file for each ticker symbol into one large table in Microsoft Access. The csv files are located at "http://ichart.yahoo.com/table.csv?s=" & tickerValue. I also need the respective ticker symbol to be loaded into each line of the table that is imported from the csv file in order to make each line unique. So the columns in the database should be: "Ticker, Date, Open, High, Low, Close, Volumne & Adj Close".
I've found information about loading a local csv file into Access but I can't seem to figure out how to load csv files from the internet into Access through vb.net.
Also, I will need to update this table frequently so I need to only insert new unique lines from the csv file. No duplicates.
Any suggestions? Thanks!

I get error code "OleDBException was unhandled. Syntax error in INSERT INTO statement." at line cmd.ExecuteNonQuery() Please help!
you may use the System.Data.OleDb Namespace to define function to make insert into the db.
Something like (in a very rough way):
Dim myConnection As OleDbConnection
Dim sConnectionString As String = "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" & DBpath & ";Persist Security Info=True"
myConnection = New OleDbConnection(sConnectionString)
myConnection.Open()
Then make a cycle on each line in the csv
Dim myInsert as String= functionTextToInsert(inputString)
Dim cmd As New OleDbCommand(myInsert, myConnection)
cmd.ExecuteNonQuery()
The functionTextToInsert(ByVal inputString as string) is a function that converts a line from the csv in a insert string: "max;min;vol" -> "Insert into MYTABLE (Column_01,Column_02,Column_03) VALUES (max,min,vol);"
Try this:
Writing large number of records (bulk insert) to Access in .NET/C#
I've never worked with DAO, so I can't be much help here, but...
if this MSSQL syntax works on MS ACCESS, use a command object and pass it a parameter containing your csv as a varchar(max), or similar access data type, which will the content of the CSV from your app:
BULK
INSERT mytable
FROM #myCSVstring
WITH
(
FIELDTERMINATOR = ',',
ROWTERMINATOR = '\n'
)
GO
Two things, the SO post states that DAO is a lot faster, and your terminators may be different, but I'd start with these.
I think the previous answers are unnecessarily complicated. All you need to do it send an XMLHTTP request. That fetches the CSV data as a string, which can then be parsed into a table.
Below is a VBA subroutine that does that. Documentation of where I found the techniques is in the code comments. I've run this in Access 2019, and it works.
The modifications of the data indicated in the question can be performed before or after inserting the data into the table.
