I use some vba to export the results of a select query. The selected data needs to be exported 1 on 1 to Excel. This morning I faced the following error:
3274 on DoCmd.TransferSpreadsheet, External table is not in the expected format
Inspecting the source data, I've found a row containing a leading Apostrophe. Removing this row from the source, solved the error. However, I need this row to be exported as well. Is there any setting to solve this problem?
This is the VBA:
lSQL = ""
lSQL = lSQL & "select a.* from table As e "
Set lQD = lDB.CreateQueryDef("Test", lSQL)
DoCmd.TransferSpreadsheet A_EXPORT, 10, "Test", FileName, True
Replace table (or lSQL) with a simple select query.
In this query, sanitize the field contents using my CSql function or similar. It will double single-quotes which, I believe, should be the cure.

I would like to use the trim function but don't really know how it works.
I need to select items in a table and export it on a CSV file.
It's working fine but sometime when I have a specific data (here it's a string), the csv file write it with à CR LF and write at the line after.
I think that a problem with the data in the data base and that there "something" after my data in this specific field.
I have this query:
string request = "SELECT * FROM " + tableName;
And I want to try this but I'm not sure.
string request = "SELECT * TRIM(TRAILING FROM ") + tableName;
if you are trying in SQL SERVER.
LTRIM(RTRIM(COLUMN))
I am very new to Microsoft Access.
I would like to select a column from a table based on the value of a parameter (i.e. my table has columns x, y and z and I have a chosencol parameter which is set by the user using a dropdown.
I can select one / all of the columns using a select command, however, I would like to do this using my parameter chosencol instead.
Having read around, I have found a number of references to using the SET and EXEC commands, however, entering them into the SQL command in Access just yields errors.
Please could someone advise me as to how I go about implementing a dynamic-sql query in Access (in fine detail as I think I am writing the commands in the wrong place at the moment...)
First I created an example table in Access.
Next, I created an example form to query your value. The dropdown is called 'chosencol'. Select a value from the Column Select dropdown and press the "Lookup Value" button.
Here is the code under the "Lookup Value" button's On Click event. A SQL statement is dynamically built with the column you chose. The column is renamed to [FieldName] to that it can by referenced.
Private Sub btnLookup_Click()
Dim rsLookup As New ADODB.Recordset
Dim strSQL As String
strSQL = "select " & chosencol.Value & " as [FieldName] from Table1 where ID=1"
rsLookup.Open strSQL, CurrentProject.Connection, adOpenForwardOnly, adLockReadOnly
If rsLookup.EOF = False Then
txtValue.SetFocus
txtValue.Text = rsLookup![FieldName]
End If
rsLookup.Close
End Sub
When the button is pushed, the value from whatever column you selected will be returned. For this simple example, I'm always returning row 1's data.
I'm pretty sure you can't do that in straight SQL. However, you can create the SQL string in VBA code and save it as a query.
CurrentDB.CreateQueryDef("MyQueryName", "SELECT " & chosencol & " FROM MyTable")
Now, MyQueryName will be a permanent query in your database and can be referenced wherever you want.
If chosencol is a multi-select dropdown, you'll have to read the selected values into an array and then write the array to one concatenated string and use that instead.
I have a table which is all VarChar() fields.
I fill the dataset with the following SQL (using vb.net):
Select * From archive_naerns90_2006_q3.NAERNS90_Calls Where siteid = 'NAERNS90-02-627303'
I get this error:
Input string was not in a correct format.Couldn't store <02-627303> in agencyid Column. Expected type is Double.
When I run this query from PgAdmin it works fine. I am running this same bit of code on dozens of other tables with no problems.
The value 02-627303 referenced in the error is the value in the agencyid column for that record, but there are no Double fields in the table. Full disclosure - there were two, but I changed them from Double to VarChar and neither were the agencyid coplumn.
The other kicker is this only happens on some records in that table.
I am guessing I have some corrupt table. I copied the table, but the copy has the same problem. And Since it works in PgAdmin but not from my code it also may have something to do with npgsql.
Edit: I was asked to add the code around the problem area as this looked like an Insert error. I am not doing any Inserts at all in this function.
SQL = "Select * From " & MlocRow("currentdb") & "." & SubTablesArr(Y) & " Where siteid = '" & DataRow("siteid") & "'"
Adapter.SelectCommand = New NpgsqlCommand(SQL, MLConnect)
Adapter.Fill(subDT)
My ConnectionString is:
"HOST=192.168.0.133;DATABASE=masterlists;USER ID=myuser;PASSWORD=mypassword"
Thanks,
Brad
You can type cast that col to varchar() explicitly...
I want to link the result of a query to a Textbox but I get this error: here is my code:
Dim rst As DAO.Recordset
Set rst = CurrentDb.OpenRecordset("SELECT XValue, YValue,Wert FROM tb_DCM_Daten WHERE (FzgID=" & Forms!frm_fahrzeug!ID & " AND Name='" & List2.Value & "')")
Text10.Text = rst!XValue //error in this line
It should be return c.a 20 record
Why do I get this error and how can I solve it?
One possible reason for the error is that Name is a reserved word in Access, so you should use
... & " AND [Name]='" & ...
You could also test for rst.EOF before trying to use rst!XValue. That is, to verify whether or not your query is returning at least one row you can add the code
If rst.EOF Then
MsgBox "The Recordset is empty."
End If
immediately after the .OpenRecordset call. If the Recordset is empty, then you'll need to verify your SQL statement as described by #GregHNZ in his comment above.
Usually, I would do this. Create a new query in Access , switch to SQL View , Paste my code there and go to Design >> Run.
SELECT XValue, YValue,Wert FROM [tb_DCM_Daten] WHERE [FzgID]=12 AND [Name]='ABC';
if your query syntax is correct you should see the result otherwise error mssg will tell where you are wrong. I used to debug a much more complicated query than yours and this is the way that I've done.
If there is still error, maybe you should try
Dim sql as String
sql = "SELECT...."
Set rst = CurrentDb.OpenRecordset(sql)
Another possible reason might be your table name. I just wonder what is your table name exactly ? if your table contains white space you should make it like this [DCM Daten].
One more thing I like to add that may cause this, is your returning a sets of resultset that has "Reserved word" fields, for example:
Your "Customers" table has field name like the following:
Custnum | Date | Custname
we know that Date field is a reserved word for most database
so when you get the records using
SELECT * FROM Customers
this will possible return "No Current Record", so instead selecting all fields for that table, just minimize your field selection like this:
SELECT custnum, custname FROM Customers
After trying the solutions above to no avail, I found another solution: Yes/No fields in Access tables cannot be Null (See allenbrowne.com/bug-14)
Although my situation was slightly different in that I only got the "No current record." error when running my query using GROUPBY, my query worked after temporary eliminating the Yes/No field.
However, my Yes/No field surprisingly did not contain any Nulls. But, troubleshooting led me to find an associated error that was indeed populating my query result with Null Yes/No values. Fixing that associated error eliminated the Null Yes/No values in my results, thus eliminating this error.
I got the same error in the following situation:
In my case the recordset returned one record including some fields with Null value.
Dim rst As DAO.Recordset
Set rst = CurrentDb.OpenRecordset("SELECT * FROM tbl WHERE (criteria)", dbOpenDynaset)
Textbox1 = rst!field1 'error in this line - Non-Null value
Textbox2 = rst!field2 'Null value
Textbox3 = rst!field1 'Null value
Viewing Locals when rst is opened and before asignments, shows the recordset as I expect it to be. The error is thrown when trying to a asign a value from this recordset.
What fixed this, is ensuring that all fields contained non-Null values.
Just posting this for future seekers.
I've got a tablea such as below, I know its bad design having multifield value column but I'm really looking for a hack right now.
Student | Age | Classes
--------|------|----------
foo | 23 | classone, classtwo, classthree, classfour
bar | 24 | classtwo, classfive, classeight
When I run a simple select query as below, I want the results such a way that even occurrence of classtwo is displayed as class2
select student, classes from tablea;
I tried the replace() function but it doesnt work on multivalued fields >_<
You are in a tough situation and I can't think of a SQL solution for you. I think your best option would be to write a VB function that will take the string of data, parse it out (replacing) the returning you the updated string that you can update your data with.
I can cook up quite a few ways to solve this.
You can explode the mv by using Classes.Value in your query. This will cause one row to appear for each value in the query and thus you now can use replace on that. However, this will result in one separate row for each class.
So use this:
Select student, classes.Value from tablea
Or, for this example:
Select student, replace(classes.Value,"classtwo","class2") as myclass
from tablea
If you want one line, AND ALSO the multi value classes are NOT from another table (else they will be returning ID not text), then then you can use the following trick
Select student, dlookup("Classes","tablea","id = " & [id]) as sclasses
from tablea
The above will return the classes separated by a space as a string if you use dlookup(). So just add replace to the above SQL. I suppose if you want, you could also do replace on the space back to a "," for display.
Last but not least, if this those classes are coming from another table, then the dlookup() idea above will not work. So just simply create a VBA function.
You query becomes:
Select student, strClass([id]) as sclasses from tablea
And in a standard code module you create a public function like this:
Public Function strClass(id As Variant) As String
Dim rst As DAO.Recordset
If IsNull(id) = False Then
Set rst = CurrentDb.OpenRecordset("select Classes.Value from tableA where id = " & id)
Do While rst.EOF = False
If strClass <> "" Then strClass = strClass & ","
strClass = strClass & Replace(rst(0), "classtwo", "class2")
rst.MoveNext
Loop
rst.Close
Set rst = Nothing
End If
End Function
Also, if you sending this out to a report, then you can DUMP ALL of the above ideas, and simply bind the above to a text box on the report and put the ONE replace command around that in the text box control. It is quite likely you going to send this out to a report, but you did ask how to do this in a query, and it might be the wrong question since you can "fix" this issue in the report writer and not modify the data at the query level. I also think the replace() command used in the report writer would likely perform the best. However, the above query can be exported, so it really depends on the final goal here.
So lots of easy ways to do this.
