GROUP BY using parameters in SQL
Here is my SQL string for a OLEDB query of a .xlsx file
szSQL = "SELECT cawo_wo_id, wows_step_id, wows_description, wffj_cur_state_desc, cawo_wo_id & wows_step_id AS p5_id FROM [" & SourceSheet$ & "$" & sourceRange$ & "] WHERE [wows_description] like '%ECR%';"
I understand that named parameters are not supported by OLEDB, but why will it not work with a 'group by' using "?" as the parameter?
Like so:
szSQL = "SELECT cawo_wo_id, wows_step_id, wows_description, wffj_cur_state_desc, cawo_wo_id & wows_step_id AS p5_id FROM [" & SourceSheet$ & "$" & sourceRange$ & "] WHERE [wows_description] like '%ECR%' GROUP BY ?;"
Thanks for any help.

Doing that would group on the value that you send as the parameter value, and grouping on a literal value is not allowed.
If you want to group on different fields dynamically, you have to create the query dynamically, not put the field name in a parameter.

My question was deleted because of duplicate but this is not the case. My example uses an already made sql-string. The answer SO does not and where SO is referring to is way to complicated to implement in my solution. I try to edit my post and be more clearly about my issue. So I have a form which connects to an external database. My query qry_LIMS selects the relevant data.
LIDNUMMER = "([LIDNUMMER] = " & LIDNUMMER_Integer & ")"
MONSTERTYPE = "([MONSTERTYPE] = '" & Monstertype_String & "')"
MONSTERNDATUM = "([MONSTERNDATUM] = '" & Datum_String & "')"
strCriteria = LIDNUMMER & "And" & MONSTERTYPE & "And" & MONSTERNDATUM
task = "Select * from qry_LIMS where (" & strCriteria & ")"
Me.Form.RecordSource = task
What is the most easy way to insert all records from task into an other table named tbl_LIMS?
The named fields of my table tbl_LIMS are the same as qry_LIMS:
Lidnummer
Monstertype
Monsterndatum
I think the solution would rather easy but I do not seem to get it
INSERT INTO tbl_LIMS VALUES (task)

using what I think is a variable in a SQL statement

I am very new to SQL and think I have a simple problem but was unable to figure it out from other posts. I have the following code:
INSERT INTO tblShortScores ( TradeNum, FilterNum, Rank, ScoreNum )
SELECT [Forms]![frmOpenTrades]![TradeNum] AS TradeNum, tblFilters.FilterNum, tblFilters.SBBExh AS Rank, tblFilters.SBBExh AS Score
FROM tblFilters
WHERE (((tblFilters.SBBExh) Is Not Null));
but instead of using the literal "SBBExh" in tblFilters.SBBExh, I want to do something like
tblFilters.("S" & [Forms]![frmOpenTrades]![Strategy])
where something like
[Forms]![frmOpenTrades]![Strategy] contains the value "BBExh".
It's in MS Access and I seem unable to find a syntax that works
any help is appreciated
Can't dynamically build field name in query object. Use VBA to construct and execute action SQL, like:
strField = "S" & Me.Strategy
CurrentDb.Execute "INSERT INTO tblShortScores (TradeNum, FilterNum, ScoreNum) " & _
"SELECT " & Me.TradeNum & " AS TradeNum, FilterNum, " & strField & " " & _
"FROM tblFilters WHERE " & strField & " Is Not Null;"
Assumes TradeNum is number type - if it is text, use apostrophe delimiters:
SELECT '" & Me.TradeNum & "' AS .

Searching a table where the field doesnt exist - Access VBA

I am a data consultant who migrates data I am sent into our system. I have written code that compares the contents of my table against what has been put into oracle, as an extra test. The tables are a little convoluted due to how they relate to each other. But essentially here is my question:
When I look to match two field values and the field doesnt exist I get a parameter pop up box. I want to only run the code if the field exists.
I have tried many things, wrapping an if statement around it but I always get the parameter box, can anyone help there must be an easier way to do this!
If Not DoCmd.OpenQuery("SELECT TOP 1" & MatchValues!FieldName & " FROM " &
MatchValues!ORACLE_TABLE_NAME) Then
MsgBox "moomins"
' strSQL = "INSERT INTO 002_TableValueErrors(ORACLE_TABLE_NAME,TRANSFORM_TABLE_NAME,FIELD_NAME,ORACLE_FIELD_VALUE,TRANSFORM_FIELD_VALUE) "
' strSQL = strSQL & " VALUES (" & MatchValues!ORACLE_TABLE_NAME & "," & MatchValues!TRANSFORM_TABLE_NAME & "," & MatchValues!FieldName & ",'ORACLE: NOT FOUND','ORACLE: NOT FOUND')"
End If
If you deal with Oracle: Have you tried to check if the field exists by querying ALL_TAB_COLUMNS in Oracle?
"Select count(*) from ALL_TAB_COLUMNS where table_name = " & MatchValues!ORACLE_TABLE_NAME & " and COLUMN_NAME = " & MatchValues!FieldName
(Untestet cause currently I have no Oracle Instance available)

SQL/ACCESS UPDATE

I am trying to update a table in Access using SQL in a VBScript. I have 2 statements that reference 2 tables. The first statement works and the second doesn't. The only difference in the two is a field name, and I cannot figure out what is wrong. I've been working on it for 6 hours now. Could anyone assist?
This works
DB.Execute "UPDATE tblDEBIT20 SET CONTROL = '" & strControl & "' WHERE DEBIT_NUM = '" & strDebit & "'"
This doesn't
DB.Execute "UPDATE tblDEBIT20 SET CURRENTNAME = '" & strCurrent & "' WHERE DEBIT_NUM = '" & strDebit & "'"
The error I get is
No value given for one or more required parameters.
I think the point being made by both Ken and Robert is that you most likely have a name with an apostrophe in it. You can either replace all single quotes (') with something else or try another quote delimiter.
See if this works for you (escaping double quotes when used inside double quotes).
DB.Execute "UPDATE tblDEBIT20 SET CURRENTNAME = """ & strCurrent & """ WHERE DEBIT_NUM = """ & strDebit & """"
A tip for you in future debugging - add a Debug.Print strCurrent before the execute command - then when it fails you can easily see what the issue is - or at least tell us what value it failed on.

VBA select not returning any rows

Below query is not returning any rows into the listbox.There is no error message:
lstDiff.RowSource = "select TestScenario,TestId from tblTesting where empid= '" & Me.txtEmpId.Value & "' and testid= '" & Me.txtAutoNumber.Value & "'"
Could anyone help?
Your values in the field are numeric, so the extra single quotes aren't needed. Code should look like the following:
Me.lstDiff.RowSource = "select TestScenario,TestId from tblTesting where empid= " & Me.txtEmpId & " and testid= " & Me.txtAutoNumber & ";"
I've also dropped .Value from the field references, they're not harmful, but also aren't necessary.
And I've added a semi-colon to the end of your statement.
Depending on when/where you insert this code, you may need to add the following statement as well:
Me.lstDiff.Requery
You keep posting questions about the exact same WHERE clause with exactly the same apparent error in each one. SO users dutifully point out your error and then a few days later, you show up with a related question utilizing the same faulty WHERE clause.
DLookup Problem:
txtContSunStart1.Value = DLookup("Start1", "tblContract", _
"TestId = " & _
lstResults.Value & _
"" And "Day = 'Sunday'")
VBA Update Query:
DoCmd.RunSQL (" Update tbltesting set IsDiff ='Yes' where empid= " & Me.txtEmpId.Value & " and testid= " & Me.txtAutoNumber.Value & ";")
VBA SQL Problem
DoCmd.RunSQL ("insert into tbltesting (IsDiff)values ('Yes') where empid= '" & Me.txtEmpId.Value & "' and testid= '" & Me.txtAutoNumber.Value & "'")
And then in the current question:
lstDiff.RowSource = "select TestScenario,TestId from tblTesting where empid= '" & Me.txtEmpId.Value & "' and testid= '" & Me.txtAutoNumber.Value & "'"
You are having difficulties with exactly the same set of problems repeatedly.
Here are the rules for concatenating SQL strings with the correct delimiters in Access:
numeric values do not need delimiters:
"... AND testid= " & Me!txtAutoNumber
text values need quote delimiters. In Access, it's general practice to use double quotes, but much easier to use single quotes since it's a pain to type double quotes in a form that will work (typing """ or """" depending on context is counterintuitive and silly to me, so I always define a global constant that holds the double quote symbol and concatenate with that).
"... AND textfield=" & Chr(34) & Me!MyTextField & Chr(34)
date values use the # delimiter:
"... AND datefield=#" & Me!MyDateField & "#"
Boolean fields require no quotes and it works best to use True and False:
"... AND IsDiff=True"
These rules apply both to WHERE clause criteria and to SET statements in UPDATE queries. The rules apply in writing a SQL string that you pass to DoCmd.RunSQL or CurrentDB.Execute, as well as to writing SQL strings to be used as the recordsource of a form or report or as the rowsource of a combo box or listbox.
Personally, whenever I use SQL statements in code, I prefer to store the statement in a variable. While testing, on the line after you assign your statement to a variable, you can use Debug.Print to see what your SQL statement looks like after parsing your txtempid and txtautonumber. It would look something like this.
Dim sSQL as String
sSQL = "select TestScenario,TestId from tblTesting where empid= '" & Me.txtEmpId.Value & "' and testid= '" & Me.txtAutoNumber.Value & "'"
Debug.Print sSQL
lstDiff.RowSource = sSQL
Then as long as your immediate window is visible (Ctrl-G), you can see what your SQL statement really is. If it looks right in the immediate window, copy and paste it into the query builder and run it there.
Try running the query in your SQL Management Studio. Do you get any row(s) back?
Edit: Just noticed the access-tag. Are you sure your table contains at least one post with supplied ids?
My Access is a bit rusty, but if all else fails try using a recordset to capture the data from the SQL and loop through it adding the values to the list box. Example Code
