Using Excel column data to create sql statement that queries database - mysql

I am looking for any advice on how i can read a single column in excel that contains 500 user_id's and query a database to display results in a WPF application. A user can own or rent so the SQL would look like;
SELECT * FROM users WHERE own= 'user_id' or rent= 'user_id'
This is fine for one user but i want to read each user_id and concatenate it to the SQL statement to pull out all results from the database. Any one have any easy way of doing this?

Variable not working inside IN clause

This code is written in Excel2010 VBA and queries PostGreSQL tables
I have the following code in VBA that creates a variable that I would like to use in my SQL query, but I cannot get the SQL query to accept the VBA variable using the IN clause
This code creates the variable I want to use and works fine. It allows me to select specific cells I need to query
Dim StaffID As Range
Dim ID As Range
Dim LR As Long
Dim SelectedID As String
'Count number of rows to search
LR = Worksheets("Sheet1").Range("A" & Rows.Count).End(xlUp).Row
On Error Resume Next 'if only 1 row
'Store Data from here
Set StaffID = ThisWorkbook.Sheets("Sheet1").Range("B2:B" & LR)
'Loop through each cell in Range and look for any character in column A
'then store offset cell value using comma delimiter
For Each ID In Worksheets("Sheet1").Range("A2:A" & LR).Cells
If ID.Value > 0 Then
SelectedID = SelectedID & "," & ID.Offset(, 1).Value
End If
Next ID
'Remove first delimiter from string (,)
SelectedID = Right(SelectedID, Len(SelectedID) - 1)
OUTPUT EXAMPLE of SelectedID = 6,7,8,6452
I now want to add this to my query using the IN clause, but it just doesn't work. Does anyone have a solution or workaround.
Sheets("Sheet2").Select
Range("A1").Select
Dim rs As Recordset
Dim t As String
t = "SELECT DISTINCT s.entity_id, u.login_name, s.role " _
& "FROM staff s INNER JOIN user u ON s.entity_id=u.staff_id " _
& "WHERE u.staff_id IN (SelectedID) " _
Set rs = conn.Execute(t)
With ActiveSheet.QueryTables.Add(Connection:=rs, Destination:=Range("A1"))
.Refresh
End With
rs.Close
At the moment you're putting the string 'SelectedID' directly into your query. You'll need something like this in your VBA:
t = "SELECT DISTINCT s.entity_id, u.login_name, s.role " _
& "FROM staff s INNER JOIN user u ON s.entity_id=u.staff_id " _
& "WHERE u.staff_id IN (" & SelectedID & ")"
Rows.Count should be fully qualified and With ThisWorkbook.Worksheets("Sheet1") and fully qualifying will make your code read better.
Function getSelectedIDSQL() As String
Dim ID As Range, StaffID As Range
Dim SelectedID As String
With ThisWorkbook.Worksheets("Sheet1")
For Each ID In .Range("A2" & .Range("A" & .Rows.Count).End(xlUp))
If ID.Value > 0 Then SelectedID = SelectedID & "," & ID.Offset(, 1).Value
Next
End With
If Len(SelectedID) Then getSelectedIDSQL = Right(SelectedID, Len(SelectedID) - 1)
End Function

In VBA Query cannot be completed

I want to find the sum of records from different tables and insert the output in a new column, when I run the code it show me the error:
"The query cannot be completed. Either the size of the query result is
larger than the maximum size of the database (2GB) or there is not enough
temporary storage space on the disk to store the query result"
And it highlight the line

What mistake I did?
And am I calling the output correctly on
ODR!New_Col= STD!TOTAL_N
If the query is too big (which the error message indicates), then let's split it into smaller chunks. This is only properly possible in MySQL, Access doesn't support LIMIT or OFFSET, workarounds are messy, especially for totals queries
I'm making a few assumptions here:
All relevant tables are stored within the same MySQL database
Your tables have valid connection strings that can be used for ADO
Note that executing the query in MySQL alone is probably enough to fix this error.

Dim sql As String
Dim STD As New ADODB.Recordset
Dim ODR As DAO.Recordset
Set ODR = db.OpenRecordset("Total_tbl")
'Create a new ADODB connection that's directly to MySQL, and doesn't use Access

Using array in WHERE clause of SQL statement using access VBA

I have an array ListBoxContents(), it will contain the items like '15', '16','25'..upto 10 items. I'm trying to retrieve data in the column Bnumber where data of length >6 and starting with('15', '16','25'...) i.e those items specified in listbox .And trying to query these listbox items in where cluase of the sql statement
Table column Bnumber contains
Bnumber
152
156
1523
16417
AA454
CC654
18A16
1826
18A16
25A76
54A16
54235A68
My VBA code
Private Sub arraywhere()
Dim qry As String
Dim Size As Integer
Size = Form_Input_From.lstdigits.ListCount - 1
ReDim ListBoxContents(0 To Size) As String
ReDim LContents(0 To 30) As String
Dim m As Integer
For m = 0 To Size
ListBoxContents(m) = Form_Input_From.lstdigits.ItemData(m)
Next m
For m = 0 To Size
qry = "SELECT col1,col2,Bnumber " & _
"FROM table WHERE (Len([table].[Bnumber]))>6) AND (Left
([table].[Bnumber],2))=(" & ListBoxContents(m) & ");"
Next m
Debug.Print qry
Application.CurrentDb.QueryDefs("[arrayqry]").sql = qry
DoCmd.OpenQuery "[arrayqry]"
End Sub
But my WHERE clause reads only last array item only. How do i specify array in where clause?
Try something like
" ... ([table].[Bnumber],2)) in ('" & Join(ListBoxContents,"','") & "');"
You are setting qry to a new statement with each iteration of your for loop. Instead you need to concatenate a string based on your list box contents that will look like ("x", "y", "z") and replace = with in.
Finish by setting your query once it will look similar to this:
qry = "SELECT col1,col2,Bnumber " & _
"FROM table WHERE (Len([table].[Bnumber]))>6) AND (Left
([table].[Bnumber],2)) in (" & commaSeperatedContents & ");"
Where commaSeperatedContents is a String that is like ("x", "y", "z") but of course has your values.
Try this one:
Dim inPart As String
For m = 0 To Size
inPart = inPart & "'" & ListBoxContents(m) & "',"
Next m
inPart = Left(inPart, Len(inPart) - 1)
qry = "SELECT col1,col2,Bnumber " & _
"FROM [table] WHERE Len([table].[Bnumber])>6 AND " & _
"Left([table].[Bnumber],2) In (" & inPart & ");"
Debug.Print qry
CurrentDb.QueryDefs("[arrayqry]").SQL = qry
DoCmd.OpenQuery "arrayqry"
The list of items in your array actually seems to be coming from the Form_Import_From_PMT.lstdigits control. Is this control bound to a data source? If so, you can simply join your table to that data source with a join clause that specifies that only rows with Bnumber values starting with the digits in the joined table are to be selected:
select col1, col2, Bnumber
from table as t
inner join tblDigits as d
on left(t.Bnumber, 2) = d.Digits
where len(t.Bnumber) > 6
If the control is not bound to a data source, then bind it now (creating a new table tblDigits to hold the digits, as shown above), and you'll be able to use the above query.
In short, data binding is how you 'use an array in a where clause' in Access.

Looping through an array and posting array to table

I am an old Foxpro programmer and I use to use arrays to post variable fields.
What I am trying to do is I have 15 date fields in the new table I designed.
In my query I have individual records with one date for activity.
I want to compile the 15 different dates for a each Client_id into one record with 15 dates but I can't seem to reference the table data as an array.
I have tried a couple different methods of defining the array but nothing seems to work.
Here is my code that I have. In my table I have 15 date fields named Mail_date1, Mail_date2, Mail_date3, etc.
I tried first defining it just as an array but did not like it; my code always fails when I try to reference the date field in the result table rs2!mdate2 = memdate(intcounter)
How can I reference my result table output fields as an array?
Do I have to put a whole bunch of if statements to load my results?
Seems like a waste.... should be able to load them as an array.
I am a new Access 2007 VBA programmer.
Dim db As DAO.Database
Set db = CurrentDb
Dim rs1 As DAO.Recordset
Dim rs2 As DAO.Recordset
Dim FinTotal, intcounter As Integer
Dim FinMPU, FinVersion As String
Dim mail_date(1 To 15) As Date
Dim memdate(1 To 15) As Date
Dim mdate2 As String
Set rs1 = db.OpenRecordset( _
"SELECT NewFile.MPU_ID, " & _
" NewFile.MAIL_DATE," & _
" NewFile.TOTAL, " & _
" Freight.Version " &_
"FROM Freight " & _
" LEFT JOIN NewFile ON Freight.[MPU ID] = NewFile.MPU_ID " & _
"ORDER BY NewFile.MPU_ID, NewFile.MAIL_DATE")
Set rs2 = db.OpenRecordset("Final")
DoCmd.RunSQL "DELETE Final.* FROM Final;"
intcounter = 1
memdate(intcounter) = rs1!mail_date
FinMPU = rs1!mpu_ID
FinTotal = rs1!total
FinVersion = rs1!Version
rs1.MoveNext
On Error GoTo Error_MayCauseAnError
Do While Not rs1.EOF
Do While Not rs1.EOF _
And memdate(intcounter) <> rs1!mail_date _
And FinMPU = rs1!mpu_ID
intcounter = intcounter + 1
memdate(intcounter) = rs1!mail_date
FinTotal = FinTotal + rs1!total
FinVersion = rs1!Version
FinMPU = rs1!mpu_ID
rs1.MoveNext
Loop
If FinMPU <> rs1!mpu_ID Then
rs2.AddNew
mdate2 = "mail_date" & CStr(intcounter)
rs2!mdate2 = memdate(intcounter)
rs2!total = FinTotal
rs2!mpu_ID = FinMPU
rs2!Version = FinVersion
rs2.Update
FinTotal = rs1!total
FinVersion = rs1!Version
FinMPU = rs1!mpu_ID
intcounter = 1
memdate(intcounter) = rs1!mail_date
End If
rs1.MoveNext
Loop
first, if you expect and answer, you should really spend more time on properly formatting your explanation and your code...
Now, for some remarks and possible answer to the question:
You should DELETE FROM Final before you open that table in a recordset.
You should be explicit about the type of recordset you are opening:
' Open as Read-only '
Set rs1 = db.OpenRecordSet("...", dbOpenSnapshot)
' Open as Read/Write '
Set rs1 = db.OpenRecordSet("...", dbOpenDynaset)
You should Dim memdate(1 To 15) As Variant instead of Date as the Date datatype cannot be Null, and since you are pulling data from a LEFT JOIN, it's possible that the returned values could be Null if there are no corresponding data to Freight in the table Newfile.
That On Error GoTo Error_MayCauseAnError should probably not be there.
Use On Error Goto only to catch errors you can't deal with at all.
Using that here will only hide errors in your code. With some proper checks statements you should not even need the On Error Goto...
It looks like your first internal loop is trying to skip some records.
However, when that loop breaks, it could be because it reached EOF, and you never test for that in the code that follows the loop.
You never test if your intcounter goes beyond the 15 allocated dates.
Are you absolutely sure that you can never have more than 15 records?
You do not say which error message you get exactly. That could be useful to help determine the kind of issue at hand.
Instead of
mdate2 = "mail_date" & CStr(intcounter)
rs2!mdate2 = memdate(intcounter)
Use
rs2.Fields("mail_date" & intcounter).Value = memdate(intcounter)
the ! syntax of DAO really only is a shorthand for the longer rs.Fields("name") form.

Possible to join two recordsets using VBA/ADO?

The goal is to join an Access table with matching data from a SQL Server table. I would do this using linked tables in Access but I'm running into Access' BigInt problem (I would have a view created to cast BigInt as Int but that isn't an option right now).
So I've been trying to create two recordsets and join them in VBA/ADO. The left side of the join would be the Access table with Season and WeekNum and the right side of the join would be the SQL Server table with Season and Weeknum and other data. This works fine until I try to create a third recordset that is the result of the join (in this example, I haven't tried to do a join, just the first part of the join by selecting from the Access recordset). I'm getting a Type Mismatch error on the line when I do Set ObjRecordset3 = "SELECT * FROM " & Access_Recordset '.
Is it even possible to join two recordsets? If so, how is this done?
Function Join()
Dim SQL_Server_Connection As ADODB.Connection
Set SQL_Server_Connection = New ADODB.Connection
Dim SQL_Server_Query As String
Dim SQL_Server_Recordset As New ADODB.Recordset
Dim Access_Recordset As New ADODB.Recordset
Dim ObjConnection As ADODB.Connection
Set ObjConnection = CreateObject("ADODB.Connection")
Dim ObjRecordset3 As New ADODB.Recordset

' Populate the SQL_Server_Recordset:

* UPDATE *
I figured out how to get to my ultimate goal which was to get data about a list of account numbers in an Access table from SQL Server based on the account number field which is common to both tables. Realizing that I can create a persistent temp table on SQL Server, I used a combination of DAO and ADO to get the values from the Access table and create a temp table. All I had to do then is run the pass-through query which references the temp table. The only odd thing (which is not a problem at this point) is if I create the temp table and run the pass-through query in VBA, this setup works. But if I create the temp table in VBA and double-click on the pass-through query, Access says that the temp table can't be found. Anyway, here's the code:
Public Sub Insert_Into_Access_From_ADO_Recordset_Using_PTQ_Simpler()
Dim dbs As DAO.Database
Set dbs = CurrentDb()
Dim cnn As ADODB.Connection
Set cnn = New ADODB.Connection
Dim rst As ADODB.Recordset
'Open SQL Server
Dim str_cnn As String
str_cnn = "MYDSN"
cnn.Open str_cnn
' Drop the temp table:
Dim str_SQL_Drop_Temp_Table As String
str_SQL_Drop_Temp_Table = "IF OBJECT_ID('tempdb..##BumpData','U') IS NOT NULL "
str_SQL_Drop_Temp_Table = str_SQL_Drop_Temp_Table & " DROP TABLE ##BumpData "
cnn.Execute str_SQL_Drop_Temp_Table
' Create the temp table:
Dim str_SQL_Create_Temp_Table As String
str_SQL_Create_Temp_Table = " CREATE TABLE ##BumpData "
str_SQL_Create_Temp_Table = str_SQL_Create_Temp_Table & " " & "("
str_SQL_Create_Temp_Table = str_SQL_Create_Temp_Table & " " & " ID INT "
str_SQL_Create_Temp_Table = str_SQL_Create_Temp_Table & " " & " , AccountNumber VARCHAR(Max)"
str_SQL_Create_Temp_Table = str_SQL_Create_Temp_Table & " " & ")"
cnn.Execute str_SQL_Create_Temp_Table
' Insert values from the Access table into the temp table
' by looping through the Access table as a recordset:
Dim rst_DAO As DAO.Recordset
Set rst_DAO = dbs.OpenRecordset("Bump Data")
Dim str_SQL_Insert As String
rst_DAO.MoveFirst
With rst_DAO
Do While Not rst_DAO.EOF
'str_Loan_Number_List = str_Loan_Number_List & "'" & Trim(rst![Loan Number]) & "'" & ","
str_SQL_Insert = " INSERT INTO ##BumpData VALUES (" & rst_DAO![ID] & ",'" & Trim(rst_DAO![Loan Number]) & "') "
cnn.Execute str_SQL_Insert
.MoveNext
Loop
End With
' Run the pass-thru query which joins to the temp table:
DoCmd.SetWarnings False
DoCmd.RunSQL "SELECT * INTO [Bump Results] FROM [Bump PTQ]"
DoCmd.SetWarnings True
End Sub
You reported this line triggers the error:
Set ObjRecordset3 = "SELECT * FROM " & Access_Recordset
The right side of the = sign attempts to concatenate a string with an ADODB.Recordset object. That is probably the immediate cause of the compile error. However, that's not the only problem with that line. Set <recordset object> = "any string value" will not work. And finally, Access SQL does not support FROM <recordset object> for any type of recordset object (ADO or DAO).
I think you should look for a simpler approach. In following query, dbo_BigIntTable is an ODBC link to a SQL Server table. It includes a field, bigint_fld, whose SQL Server data type is BigInt. However, Access sees that field as Text type. Therefore I can join it with the string equivalent of a Long Integer field (tblFoo.id).
SELECT tblFoo.id, dbo_BigIntTable.bigint_fld
FROM
tblFoo
INNER JOIN dbo_BigIntTable
ON CStr(tblFoo.id) = dbo_BigIntTable.bigint_fld;
The Access query designer complained it can't display that join in Design View, but I was able create the join from SQL View and it worked fine.
