Access 10 to Excel 10 Exportation only partially working, any ideas?

[Rebecca McCallan]

I am exporting some data from Access to Excel, I have used this code before and it worked perfectly. I have 2 tables which I am trying to export, contacts and company details. When clicking export on the contacts form, it works perfectly whereas clicking on the company export button does not work. It is using the exact same code and so I do not see what could be making one work and the other not... does anyone have any ideas? Or suggestions as to what I should check?

Thanks

Rebecca

Hi Rebecca. We'd need to see the code you are mentioning which worked before. Without it there is too little detail to even hazard a guess about what might or might not be wrong.

If you could post the code behind your command button etc. it would be appreciated.

Well, there's no obvious problem with the code concerned that I can see from checking the content.

Given that we don't have your application to hand and you do, you'll need to do some digging to find out exactly what happens when you click on the Company export button (as we need to know much more about what is happening than 'it doesn't work' to be able to give you suitable advice!).

You'll need to approach this from a debugging perspective and set a break point in the On Click event handler for that button, then use the F8 key to single-step through your code to find out what exactly is being done.

If you need some help on what debugging is about we have an Insights article on Debugging in VBA which may be of use, linked here.

I have done that and tried to work it out myself, basically what happens is an error appears 'too few parameters'. The code errors on this line: Set rstexport = db.OpenRecordset("SELECT " & strselect & " FROM " & strObjectName)
Presumeably this means an error with the specified recordset, I have looked at the recordset and cannot see what could be wrong with it. The recordset consists of the following fields if it helps: CompanyName, CompanyAddress, TownCity, Postcode, ContactNumber1, WebsiteAddress, VATNumber, CompanyContact, CompanyType

Don't worry now I've found the answer

[Stewart Ross]

Hi Rebecca. For interest, what was wrong? The error message you mention normally arises if a field mentioned in the WHERE clause of the SQL statement does not correspond to a field that the SQL interpreter can access. This can happen if a field is renamed or removed, for example.

By the way, I notice that lines 20 and 24 in the code you posted duplicate each other; it is not a good idea to open a recordset and then re-open the same one for the same object variable. I'd guess that line 24 can be deleted, but you'd need to confirm this by testing. Line 20 cannot be, as the recordset is referred to immediately after.

Hi, If you read the table name opened in line 20 and 24 they are actually two different tables, export and export detail as they have different information within them. Yes the problem was that a field name in the table did not correspond to a field name in the query (it was quite a subtle difference so took me a while to notice).

Thanks for trying to help anyway!
