Mean Time Between Failure
Sep 26, 2007
I'm fairly new to Access, so maybe someone can school me here...
I have a issue tracking database query reporting a serial number in the first column, an open issue date in the second column and close issue date in the third column. There can be several instances of each serial number.
I already figured out how to use DateDiff to get a time to fix column...
I want to have a column reporting the difference between the previous close date to the next open date (grouped by serial number).
Example
S/N Open Date Close Date Time to Fix MTBF
1234 1/10/2007 1/13/2007 3 5
1234 1/1/2007 1/5/2007 4
2222 1/2/2007 1/3/2007 1

have a DB which is working fine on most PCs (approx 15 users) I do however have a problem sending emails from some machines (using a macro to do the send object as example below) The mail program used is Outlook 2000 / 2003
DoCmd.SendObject acReport, "Returns Notice", "SnapshotFormat(*.snp)", "to a defind list", True, ""
This works fine BUT on most machines but on a couple we get a fail message when attempting to send, this message is unspecific. I cannot find any different settings on the machines in question, the op system is 2000 / XP.
I operate the same program on my PC running XP prof servpk 2 and although 99% of the time the emails go through without issue I do sometimes have the same problem. Re-booting does not resolve it! and I can find no trend as to why I have the problem.
Any thought or advise welcome.

Hello again all... Today's problem is as follows.... I have an "after update" combo box that is coded as "CurrentDb.Execute "uno", dbFailOnError". I have an SQL Query named "uno" that is showing the following: "UPDATE [Input] SET [Input].Loc_Lng = [Loc-1L].Combo8, [Input].Loc_ID = "1", [Input].Loc_Desc = "xxxx";" I am trying to have the combo box update the values from the combo box into a blank table. When I try to run this, it comes up with the error: "Too few parameters. Expected 1". Any idea what that means, and then how to fix?

Hi all
I'm stuck on the following SQL statement. It looks OK to me... but there must be something wrong with it because it doesn't execute.
I've tried the runSQL command and I've tried currentproject. connection.execute as well. Both fail to execute... it has to be the SQL string below.
Thanks for any advice.
SQLImportPE = "UPDATE data INNER JOIN data_import ON data.ID = data_import.ID" & _
"SET data.pe1 = data_import.pe1, data.pe2 = data_import.pe2, data.pe3 = data_import.pe3, data.pe4 = data_import.pe4, data.pe5 = data_import.pe5, data.effort_pe = data_import.effort_pe" & _
"WHERE (((data_import.pe1) Is Not Null));"

When I highlight a combo box, the default hotkeys should be alt+down or f4 to drop the menu down.The issue I'm having is that while alt+down works, f4 does not. I just got a new computer in my office, and f4 worked on the old one.My keyboard does not have a f-lock key on it. That seems to be the internet's general response to my problem, but that doesn't work.

hi There
I Have A Database Trying To Convert It To MDE I Get The Following Message
--------------------------------------------------------------------------
This error is usually associated with compiling a large database into an MDE file. Due to the method used to compile the database, a considerable number of TableID references are created for each table. The Microsoft Jet database engine version 4.0 can only create a maximum of 2048 open TableIDs at one time. Exporting a database as an MDE potentially can exceed this limit if the database has a large number of objects (table, macro, form, report, etc).
There is no accurate method to estimate the number of TableIDs the Jet database engine uses during the process of compiling a database as an MDE. However, each VBA module and each form uses one TableID, as a result, if the database has 500 forms, and each form's HasModule property is set to Yes, as many as 1,000 TableIDs are used.
Any Help Please
Thank You In Advance

My Access table has a record which my update query was unable to locate. This issue resolved when I removed the primary key and applied it again.

I admin an Access 2007 ADP that is distributed to our user base as an ADE. The back end is MSSQL 2005. Recently, we have begun deploying this software to employees in the field who connect to the corporate network via VPN. Because our field employees are sometimes connecting from some seriously flaky Internet connections, we have seen an uptick in Connection Failure errors.
I've been researching ways to detect and reestablish a failed network connection from VBA so that the user doesn't encounter the errors, or the need to close and reopen the application to continue working. This post appears to get me most of the way there, in that it both suggests a way to detect the failure and reestablish a connection on the fly:
[URL] ....
Basically, it suggests replacing the call to CurrentProject.Connection with a call to your own custom function, looking something like this:
Code:
Function fCurrentConnection () As ADODB.Connection
If CurrentProject.Connection.State = 0 Then
CurrentProject.OpenConnection "YourConnectionString"
End If
Set fCurrentConnection = CurrentProject.OpenConnection
End Function
My problem is that I define my connection in the built in server properties of the project. My users connect using Windows NT Integrated security. I don't know what I should put in the "YourConnectionString" area. Is there a way to tell Access to use the stored settings to reconnect, or alternatively, any example string that connects to a server name and database name using Windows NT Integrated security?

I have an append query which fails due to validation rules. There are no field validation rules, only enforced table relationships. There is an autonumber field which I am omitting from the INSERT and SELECT clauses in the hopes that it will take its next value.
How do I determine which fields are causing the problem? I have changed the query to a simple SELECT and manually typed in the resulting values with no problems. Note that ALL records I am attempting to add fail the rules.

Hi,
I feel a little silly bringin this up but I have gone through the solutions provided on this topic but it all doesnt seem to work.
I am trying to up date my Products table with data from two other tables (Sales and Stock Receipt). I have made sure the data types in all the tables are the same (currency) but I still get this message
"Microsoft Access did not update 5 field(s) due to a data type conversion failure."
This is the expression I'm using in the update query
IIf(IsNull(DSum("[Quantity]","Sales Detail","Sales Detail.[ProductID]=" & [Products].[ProductID])),[Products]![OpeningStockAmt],[Products]![OpeningStockAmt]-(DSum("[Quantity]","Sales Detail","Sales Detail.[ProductID]=" & [Products].[ProductID])*[Products]![CostAmountperUnit]))

Hi,
I am having problems with a DLOOKUP expression in an update query.
I have set up a lookup table (imported from Excel and another table set up myself because of this error) with a date field and a week number field and I am trying to return the week number into another table for the date in another field. It is easy to do in Excel (VLOOKUP), but I have never done this in Access.
I am attempting to get the update query to update another table which has a Date of Booking and a new week number field. When I run the query, it has the error message that it cannot update all of the records, due to a type conversion failure. I thought that this error was due to fields have dissimilar data types and changed them until they were exactly the same - the Week Number are both Long Integer number fields and the dates are a General Date date fields.
The expression is: DLookUp("DLOOKUP Created.Week Number","DLOOKUP Created","Date = " & [2004 Lookup].[Date of Booking]). The lookup table is DLOOKUP Created and this is the return value I want. The 2004 Lookup table is the table that I want to update with the week number, using the date of booking.
Any help will b gratefully receive.
All the best,
Roly

Hi all,
We have an Access 2000 db on a server that I can open.
Problem is, when other users open it up and use the Navigation buttons to say, view the next record, Access crashes with the following error:
"Method 'Requery' of object '_Subform' failed." (this is the Access supplied record navigation functionality - I havent customised it in any way)
Other users have been using it before with no problem (upto last week). I can still open the db and do not have any errors...
So, it appears to be a user related problem.
Any suggestions or things I should check out, please?
Many thanks,

Good afternoon all,
I have a macro that I run. In this macro, I've changed the "SetWarnings" to No. This works since I do not get a "Are you sure..." when I do a makeTable query and the table already exists.
However, I do get a type conversion failure error message.
Does someone know how I click Yes on this without any intervention on my part when the macro is running? Would entering keystrokes in the macro work? I don't think that they will since the next command is not called until the previous has executed ... and I'm getting hung up on the dialog box before the make-table command has finished execution.
I've attached the error message text that I'm seeing.
Thank you for your time and help.

Hi guys.
I got a problem with my access database. I'm using the code as below in a access function.
Code:Dim rst As ADODB.RecordsetSet rst = New ADODB.RecordsetstrSQL = "select * from tbl1 where fldDate between #08/22/2005# and #08/28/2005#" rst.Open strSQL, CurrentProject.Connection, adOpenStatic
When I get to the last line, It will cause a "catastrophic failure" on my computer, whilst on others it will run just nicely.
I'm thinking some sort of version problem, but wouldn't know where to look...
..help..

I am trying to import records from Excel and I have two issues:
1) I have imported the excel file into a new table and I get type conversion errors just for fields 25, 26, 28 and 29 (and only for rows 2 to 25) but there aren't that many fields in the table.
2) The second is that I get key violations even though the indexing for all the fields for "table_candidate" is set to "no" (apart from the "cand_ID").
I can't see anything wrong with the records.

In the highlighted line of code attached I am comparing two strings one from a snapshot recordset and one from an array.
The logic fails, you can see in the watches window both values equal "DESIGN and the elseif statement should execute but it does not.
The only reason I can see for this is that the values are equal to "DESIGN and not DESIGN. Where this single quotation mark comes from I do not know. It is not visible in the tables and it does not appear when the values are printed into excel.

I have a routine which connects to MySQL database with ADODB connection. This worked in 2003 and 2007 runtime but throws a 430 error on 2010 runtime. It works in full access 2010. Has there been a change of policy to restrict this type of connection in the 2010 runtime? If I use a linked ODBC table instead of ADODB the runtime fails with "Runtime Error". It still works in full access.

I keep getting the above error in access 2010 and cannot see where the error is. I have checked that datatypes are the same. It keeps referring to type conversion failure and didn't add (1) record due to a key violation.
Code:
INSERT INTO Requests ( [Request no], [Date-time received], Customer, Dept, Type, [Service level], [Received by], [Date-time due], Quantity, [Cust requestor], Status )
VALUES (9896, NOW(), 'DEMO', 'Demo Ltd', 'I', 'S', 'LT', NOW(), 1, 'LT', 'O');

I am trying to import an Excel spreadsheet into an Access 2007 database. Each time I import, Access creates a 'type conversion failure' error database.
I set up the first field in my .db to be a TEXT field because the Field will have both numeric and text characters. The field name is [estimate number] with numbers such as 656111 or 65611A being imported. All the fields with the numeric and alphabetical combination (i.e. 65611A) are not being imported (which results in the creation of the error db).

I need to import an excel spreadsheet into an existing Access 2003 table. Due to regulations, the spreadsheet cannot be linked.
When I try to import the spreadsheet, I receive a 'Type Conversion Failure' associated with a 'Product ID' field. In the Excel file, this column is populated with two types of values-- either a 9 digit number, or a 9 digit alpha numeric value. The 9 digit numbers import correctly, but the alpha numeric values fail.
Field names/layout in the excel spreadsheet are identical to the Access table, and the field type in the existing Access table is set to 'text.' There is no set Format, or Input Mask.
What I could change with the existing table to make this import work? I'd like to avoid importing a new table, as this would force me to recreate a number of relationships after each import.

I have created a make table query and using expressions for two of the fields. I have set the field properties (format) to "Percent". The expressions are calculating rates based on two other fields. The expressions are currently as such:
PTD_CM_PGM_RATE: IIf((IsError([PTD_CM_REPT_PGM]/[PTD_CM_REPT_ER])),"0%",[PTD_CM_REPT_PGM]/[PTD_CM_REPT_ER])
I'm using the IIF function to avoid potential errors should one or both of the values ("PTD_CM_REPT_PGM" or "PTD_CM_REPT_ER") be zero.
However, when running the query, I am getting the "...type conversion failure is caused when the data in one or more fields doesn't match...." error.

I have an application with a backend db on PC 1, and the same application on PC 2 linked to the backend db on PC 1 via the network.
The link works fine but the time formats are different.
On PC 1 the time format is shortime and displays as it should i.e. in 24 hour clock format
However on PC 2, opening the same database via the network, the time format is still shorttime but when you read the time within the code it comes out in AM/PM format. Also, when the defaul tiem should be #20:00:00# but this changes to #8:00:00 PM#
Weirdly though, when you just open the table, the times are in the correct shorttime format.
Guessing, it must be a setting within the main core of Access 2003 that is different between the 2 instances?
Any ideas?
This screen shot may help:
