Performing SQL queries taking inputs from Excel Table in VBA Macro - mysql

I would like to take inputs from a table in Excel to perform SQL query and output it to a location in the Excel sheet.
Macro:
Sub SQL(Dim strSQL as String)
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
strFile = ThisWorkbook.FullName
strCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & strFile _
& ";Extended Properties=""Excel 12.0;HDR=Yes;IMEX=1"";"
Set cn = CreateObject("ADODB.Connection")
Set rs = CreateObject("ADODB.Recordset")
cn.Open strCon
rs.Open strSQL, cn
Debug.Print rs.GetString
End Sub
SQL Query:
SELECT
e.`isin`,
b.*
FROM
`risk_reference`.`basket_debt` AS b
JOIN `risk_reference`.`etp` AS e
ON IF(
e.`parentid_override` > 0,
e.`parentid_override`,
e.`parentid`
) = b.`parentid`
AND e.`isin` = ?
AND e.`date_out` IS NULL
WHERE b.`processing_date` IN
(SELECT
MAX(processing_date)
FROM
`risk_reference`.`basket_debt`)
GROUP BY e.`isin`, b.`pk_id`
The ? in the SQL query is where I need a list of items to go in based on a table in Excel.
Should i do SQL query item by item or can i do it in one shot? If so, how do i do it? If I do line by line, how do I get to output one location in the excel?
Need some advise.

Assuming your variant of sql supports it, use IN and loop through cells to buiold the list
strsql = "SELECT e.`isin`, b.* FROM `risk_reference`.`basket_debt` AS b JOIN "
strsql = strsql & "`risk_reference`.`etp` AS e ON IF( e.`parentid_override` > 0, "
strsql = strsql & "e.`parentid_override`, e.`parentid`) = b.`parentid`"
strsql = strsql & "AND e.`isin` IN ("
dim c as range
for each c in range("your range here")
strsql = strsql & "'" & c.text & "',"
next c
strsql = strsql & ") "
strsql = strsql & "AND e.`date_out` IS NULL WHERE b.`processing_date` IN "
strsql = strsql & "(SELECT MAX(processing_date) FROM `risk_reference`.`basket_debt`) "
strsql = strsql & "GROUP BY e.`isin`, b.`pk_id`"

Use multiple alias from SQL query as header of columns in Excel

With reference to this question I run the below query to
a) get the campaigns in Column A and
b) include the alias in the SQL as header for the Column A.
Sub ConnectDB5()
Dim conn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim dateVar As Date
Set conn = New ADODB.Connection
conn.ConnectionString = "DRIVER={MySQL ODBC 5.1 Driver}; SERVER=localhost; DATABASE=bi; UID=username; PWD=password; OPTION=3"
conn.Open
strSQL = " SELECT 'campaign' UNION ALL SELECT " & _
" cID AS Campaign " & _
" FROM PDW_DIM_Offers_Logistics_history " & _
" WHERE DATE(insert_timestamp) = ""2020-02-24"" "
Set rs = New ADODB.Recordset
rs.Open strSQL, conn, adOpenStatic
Sheet4.Range("A1").CopyFromRecordset rs
rs.Close
conn.Close
End Sub
This query works perfectly.
Now, I added one additional column in the SQL query:
Sub ConnectDB5()
Dim conn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim dateVar As Date
Set conn = New ADODB.Connection
conn.ConnectionString = "DRIVER={MySQL ODBC 5.1 Driver}; SERVER=localhost; DATABASE=bi; UID=username; PWD=password; OPTION=3"
conn.Open
strSQL = " SELECT 'campaign' UNION ALL SELECT " & _
" cID AS Campaign, " & _
" SUM(order_quantity) AS Quantity" & _
" FROM PDW_DIM_Offers_Logistics_history " & _
" WHERE DATE(insert_timestamp) = ""2020-02-24"" " & _
" GROUP BY 1"
Set rs = New ADODB.Recordset
rs.Open strSQL, conn, adOpenStatic
Sheet4.Range("A1").CopyFromRecordset rs
rs.Close
conn.Close
End Sub
With this I get:
runtime error '-2147217887 (80040e21)'
What do I need to change in my VBA to
a) get the campaigns in Column A and the Quantity in Column B
b) include the alias in the SQL as header for the Column A and Column B?
I think you need to fix the heading row:
strSQL = " SELECT 'campaign', 'Quantity' UNION ALL SELECT " & _
UNION requires all dataset to have the same number of columns.
When you use union you must have the same number of columns in your selects.
Try this:
strSQL = " SELECT 'campaign', '' AS Quantity UNION ALL SELECT " & _
" cID AS Campaign, " & _
" SUM(order_quantity) AS Quantity" & _
" FROM PDW_DIM_Offers_Logistics_history " & _
" WHERE DATE(insert_timestamp) = ""2020-02-24"" " & _
" GROUP BY 1"
In your first select the Quantity column will have nothing like result.

Please guide me.. on my below error.
In table2 column Sr after # there are some number's which is similar to table1 column Sr number's.I want to do inner join as per that particular number.
required output.
Start by writing Option Explicit on top of the module. Why does my code run without 'Option Explicit' but fail with it?
Then change the Sub sql() to something like this:
Function sql_string() as string
sql_string = "Select [Sheet1$].[Sr], [Sheet2$].[Name], [Sheet2$].[Value] From [Sheet1$]" & _
" Inner Join [Sheet2$] On CInt([Sheet1$].[Sr]) = CInt(Mid([Sheet2$].[Name],InStr(1,[Sheet2$].[Name],""#"")+1))"
end sub
In the immediate window, write ?sql_string and see what you get.

Query Returns Multiple Rows Instead of the max

I have a table in Access with the relevant fields EFTRecID, EFTRecIDNum and CreatedBy. EFTRecIDNum is an auto number field, and EFTRecID concatenates the required format of "CE" & EFTRedIDNum. I am attempting to return the highest value in the EFTRecID field that was created by the current user. To do this I am trying to do a sub query that finds the Max(EFTRecIDNum) WHERE Created = my name. However instead of returning the max, it is returning all values with my name. I know I could use the format option to just format the EFTRecIDNum field, but I need to be able to search in the format CE456.
TL;DR: Query returns all records with my name, rather then max with my name.
Public Sub DownloadMyRecords()
Dim intI As Integer 'Used for looping in a variety of locations
strSQL = "SELECT EFTRecID FROM tblEFTRec WHERE (SELECT MAX(EFTRecIDNum) FROM tblEFTRec WHERE CreatedBy = '" & Application.UserName & "')"
Set cnn = New ADODB.Connection
With cnn
.Provider = "Microsoft.ACE.OLEDB.12.0;Data Source=" & dbLocation & "\" & dbName & ";Jet OLEDB:Database Password=" & DBPWord
.Open dbLocation & "\" & dbName
End With
Debug.Print strSQL
Set rst = New ADODB.Recordset
rst.CursorLocation = adUseServer
rst.Open Source:=strSQL, ActiveConnection:=cnn, _
CursorType:=adOpenForwardOnly, LockType:=adLockOptimistic, _
Options:=adCmdText
Debug.Print (rst.GetString)
rst.Close
cnn.Close
Set rst = Nothing
Set cnn = Nothing
End Sub
Try this SQL statement instead:
strSQL = "SELECT EFTRecID
FROM tblEFTRec
WHERE EFTRecIDNum = (SELECT MAX(EFTRecIDNum) FROM tblEFTRec WHERE CreatedBy = '" & Application.UserName & "')"
Try using:
"SELECT EFTRecID FROM tblEFTRec
WHERE EFTRecIDNum = (SELECT MAX(EFTRecIDNum) FROM tblEFTRec
WHERE CreatedBy = '" & Application.UserName & "')"
Is there a reason the following doesn't work?
"SELECT MAX(EFTRecID) FROM tblEFTRec
WHERE CreatedBy = '" & Application.UserName & "'"

How to check for record by using ID, then if record exists update if not add new record

I've create an excel userform to collect data. I have connected it to Access to dump the data. However I want to update Access every time a user presses the submit button.
Basically I need the Select statement to determine an id existence, then if it doesn't exists I need to use the INSERT to add the new row. I'm very new with any SQL so any help would be great.
Here is the code I have now, I need to adapt it to ADO.
Sub Update()
Dim cnn As ADODB.Connection
Dim MyConn
Dim rst As ADODB.Recordset
Dim StrSql As String
Set cnn = New ADODB.Connection
MyConn = ThisWorkbook.Path & Application.PathSeparator & TARGET_DB
With cnn
.Provider = "Microsoft.ACE.OLEDB.12.0"
.Open MyConn
Set rst = New ADODB.Recordset
rst.CursorLocation = adUseServer
rst.Open Source:="Foam", ActiveConnection:=cnn, _
CursorType:=adOpenDynamic, LockType:=adLockOptimistic, _
Options:=adCmdTable
StrSql = "SELECT * FROM Foam WHERE FoamID = " & txtMyID
Set rst = CurrentDb.OpenRecordset(StrSql, dbOpenDynaset)
If (rst.RecordCount = 0) Then
DoCmd.RunSQL "INSERT INTO Foam (ID, Part, Job, Emp, Weight, Oven) VALUES " & _
"(" & txtID & ", '" & txtField1 & "', '" & txtField2 & "', '" & txtField3 & "', '" & txtField4 & "', '" & txtField5 & "' );"
End If
' Close the connection
rst.Close
cnn.Close
Set rst = Nothing
Set cnn = Nothing
End With
End Sub
I revised your code sample just enough to get it working on my system and tested this version in Excel 2007.
When I use a value for lngId which matches the id of an existing record, that record is opened in the recordset and I can update the values of its fields.
When lngId does not match the id of an existing record, the recordset opens empty [(.BOF And .EOF) = True]. In that situation, I add a new record and add the field values to it.
Sub Update()
Const TARGET_DB As String = "database1.mdb"
Dim cnn As ADODB.Connection
Dim MyConn As String
Dim rst As ADODB.Recordset
Dim StrSql As String
Dim lngId As Long
Set cnn = New ADODB.Connection
MyConn = ThisWorkbook.Path & Application.PathSeparator & TARGET_DB
With cnn
.Provider = "Microsoft.ACE.OLEDB.12.0"
.Open MyConn
End With
lngId = 4
StrSql = "SELECT * FROM tblFoo WHERE id = " & lngId
Set rst = New ADODB.Recordset
With rst
.CursorLocation = adUseServer
.Open Source:=StrSql, ActiveConnection:=cnn, _
CursorType:=adOpenDynamic, LockType:=adLockOptimistic, _
Options:=adCmdText
If (.BOF And .EOF) Then
' no match found; add new record
.AddNew
!ID = lngId
!some_text = "Hello World"
Else
' matching record found; update it
!some_text = "Hello World"
End If
.Update
.Close
End With
Set rst = Nothing
cnn.Close
Set cnn = Nothing
End Sub
Using VBA, here is a sample of how to query for a certain ID to check if it exists. If it does not then add it via an INSERT statement:
Dim rs As DAO.Recordset
Dim StrSql As String
StrSql = "SELECT * FROM MyTable WHERE ID = " & txtMyID
Set rs = CurrentDb.OpenRecordset(StrSql, dbOpenDynaset)
If (rs.RecordCount = 0) Then
DoCmd.RunSQL "INSERT INTO MyTable (ID, Field1, Field2) VALUES " & _
"(" & txtID & ", '" & txtField1 & "', '" & txtField2 & "');"
End If

Copy Row to same Table in new Database

I have very little experience with Access Databases however I have wrote a similar VBA macro in excel. I am trying to copy rows from one .mdb file into the exact same table on a different .mdb file. However I would like it to only import it if it does not already exsist. Could someone please advise me the best way to go about this and maybe some code I can use and modify? I have already looked around stack overflow and can't seem to find any examples that work.
There are 8 different tables and inside these a few hundred rows. with maybe 5-20 columns.
If the script could be made inside VBS this would be ideal, as it would allow me to run the updates without loading into access.
Thanks for any help or advice,
Simon
EDIT -
Zev's answer seems to do the job however I am getting this error, also the MDB inside site2 is the one I am copying from and putting it into site1
Error: Expected end of statement

End Sub
Edit for more info:
\Site1\ActinicCatalog.mdb - is destination database
\Site2\ActinicCatalog.mdb - is original database
These databases have about 20 columns
Here is an example to get you started. It copies the content of [Table1] of the current database to [Table1] of a second database.
Option Compare Database
Option Explicit
Sub copyTables()
'Open source database
Dim dSource As Database
Set dSource = CurrentDb
'Open dest database
Dim dDest As Database
Set dDest = DAO.OpenDatabase("C:\Users\Admin\Desktop\DBdest.accdb")
'Open source recordset
Dim rSource As Recordset
Set rSource = dSource.OpenRecordset("Table1", dbOpenForwardOnly)
'Open dest recordset
Dim rDest As Recordset
Set rDest = dDest.OpenRecordset("Table1", dbOpenDynaset)
'Loop through source recordset
While Not rSource.EOF
'Look for record in dest recordset
rDest.FindFirst _
"Field1 = '" & rSource.Fields("Field1") & "' AND " & _
"Field2 = " & rSource.Fields("Field2")
'If not found, copy record - Field1 is text / Field2 is numeric
If rDest.NoMatch Then
rDest.AddNew
rDest.Fields("Field1") = rSource.Fields("Field1")
rDest.Fields("Field2") = rSource.Fields("Field2")
rDest.Update
End If
'Next source record
rSource.MoveNext
Wend
'Close dest recordset
rDest.Close
Set rDest = Nothing
'Close source recordset
rSource.Close
Set rSource = Nothing
'Close dest database
dDest.Close
Set dDest = Nothing
'Close source database
dSource.Close
Set dSource = Nothing

I would suggest using an SQL statement if possible. From VBScript using DAO/ACE:
Dim eng
Set eng = CreateObject("DAO.DBEngine.120")
Set dest = eng.OpenDatabase("path\to\destination\database.accdb")
Using ADO:
Dim conn
Set conn = CreateObject("ADODB.Connection")
With conn
.Provider = "Microsoft.ACE.OLEDB.12.0"
.ConnectionString = "Data Source=""path\to\destination\database.accdb"";"
.Open
End With
The SQL statement would be something like this:
INSERT INTO Table1
SELECT *
FROM Table1 AS t1 IN "path\to\source\database.accdb"
WHERE Table1.Field1 <> t1.Field1
and executed like this:
Dim sql = _
"INSERT INTO Table1 " & _
"SELECT * " & _
"FROM Table1 AS t1 IN "path\to\source\database.accdb" " & _
"WHERE Table1.Field1 <> t1.Field1"
'Using DAO or ADO
dest.Execute sql
Considering that each table has a variable number of columns, you might have to generate the WHERE expression dynamically:
Sub CopyTable(tablename)
Dim rs
Set rs = dest.OpenRecordset(tablename)
'if using ADO:
'Set rs = conn.Execute(tablename)
Dim sWhere
For Each fld In rs.Fields
sWhere = sWhere & " AND " & fld.Name & " <> t1." & fld.Name
Next
sWhere = Mid(sWhere, 6)
Dim sql
sql = _
"INSERT INTO " & tablename & " " & _
"SELECT * " & _
"FROM " & tablename & " AS t1 IN ""path\to\source\database.accdb"" " & _
"WHERE " & sWhere
dest.Execute(sql)
End Sub
Update
If you are only using one column to determine whether the record exists, the SQL statement should look like this:
INSERT INTO Table1
SELECT *
FROM Table1 AS t1 IN "path\to\source\database.accdb"
LEFT JOIN Table1 ON t1.FirstField = Table1.FirstField
WHERE Table1.FirstField IS NULL
and CopyTable like this:
Sub CopyTable(tablename)
Dim rs
Set rs = dest.OpenRecordset(tablename)
'if using ADO:
'Set rs = conn.Execute(tablename)
Dim field0Name
field0Name=rs.Fields(0).Name
Dim sql
sql = _
"INSERT INTO " & tablename & " " & _
"SELECT * " & _
"FROM " & tablename & " AS t1 IN ""path\to\source\database.accdb"" " & _
"LEFT JOIN " & tablename & " ON t1." & field0Name & "=" & tablename & "." & field0Name & " " & _
"WHERE " & tablename & "." & field0Name & " IS NULL"
dest.Execute(sql)
End Sub
