Tables :: Type Conversion Failure And Key Violations
Jan 23, 2014
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.

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.

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

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.

I have an update query:
Query: DateExtractor
--------------------------------
Type: update query
Field: ProductionDate
Table: Production
Update To: DateSerial("2000"+Val(Mid([Code];1;2));"Mid([Code];3;2)";"Mid([Code];5;2)")
Field [Code] is a Text field and ProductionDate is Date/Time type, with short date format.
As I run query, there's an error that says "Microsoft Access didn't update 99 field(s) due to DateSerial,..."

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 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've got a CSV file that was created using SAS software. The CSV file has column titles in the first row. When I attempt to import the CSV file into Access 2007, some fields give a "Type Conversion Failure" error message.
These offending fields usually start with data that appears all numeric, although the column should be text, and the error occurs when an alphanumeric cell is encountered. In other words, it seems that Access 2007 is automatically switching to numeric based on what is initially encountered in a column.
Is there a way to tell Access to not do this type of recognition? Is there something else I must do to prevent this error from happening? Is there perhaps a piece of code I could use to eliminate these errors?
Thanks in advance to all who reply....looking forward to hearing from you!

I have a linked table using ODBC. The table linked has improper field type: all numeric fields are linked as decimal. Because of this if I want to import the contens of this linked table in one new, the database has high dimension.
find a place where I can set the field conversion for linked tables or to make Access to performe the better type conversion (if the field is integer on source table to be integer on linked table as well and so on).

Hi Gurus, need your help yet again.
I have a linked table in Access 2007(link back to SQL Server), and when i look into the values of a 'Memo' Column called "Column_1" in Access, it is just fine.
Now, In a query I am doing the following IIF statement:
Expr1: IIF([table_1].[Column_2]="Cost",[table_1].[Column_1]
But when i see the values of Column_1 now, some of the ending characters are being cut off, i only get half of the entire text.
Should i be doing any type-casting or anything to bring the entire text?
Any help is appreciated.
Thanks,
Kon

Hello,
I have getting type conversion errors for numeric and currency fields when importing an Ecxel spreadsheet into a Table in Access. I have tried changing the data type to text in Excel, and that is what it says I have done when I examine the field formats in question. How can I force this to be text, it keeps reverting,
i.e. the fields in question, to numeric and currency. Can anyone help? Thank you.

hello once again,
I need to import a text file into an existing table in Access. The text file has been imported once and is working well and everything. However, since I had to change some of the datatypes to be able to query the table correctly, I now cannot import the text file anymore unless I change the datatype of the table itself. Since someone other than I will be doing the imports from here on out, changing the datatypes everytime is out of the question. I was looking at the TransferText event, but I didn't seem to see anything about converting data types. I can think of two options, and neither are probably possible:
1. import using the wizard. Since I didn't see anything related to the types of data, I don't think this will work...
2.import using TransferText. This doesn't seem to give me any opportunity to change the datatypes either. Is there anyway to programmatically change datatypes, or is there possibly an easier way that I'm overlooking??
thanks in advance,
*j

Here's my Goal: To open a saved query that has a parameter, setting that parameter via a VBA sub.
Here's my Problem: I was getting various errors, but after debugging my program a bit, it comes down to a "Data Type Conversion Error"
Here's my Code:
Set db = CurrentDb
Set qd = db.QueryDefs("qryMY_DATA")
qd.Parameters(0) = Me.txt_ReferenceID
Set rs = qd.OpenRecordset("qryMY_DATA", dbDynaset)
Code:
'*** Database Variables
Dim db As DAO.Database, rs As DAO.Recordset, gq As DAO.QueryDef, prm As DAO.Recordset
I've been all over the forums and tried several different approaches, all to no avail. The Query runs fine in the QDT, but kicks back an error when I try to run it from my sub.

I'm building a database at work to see if we can replace some of the "buhzillion" spreadsheets we currently use to track data on sites and employees across the country. I've set up the primary excel tables the way I want to import them, but Access keeps converting my Employee Numbers (mostly 7 digit numbers, "text" format in excel) to scientific notation during the import process and then giving me errors because my primary key "EmployeeNumber" has duplicates. How do I tell Access to import these as text instead of numbers? I'd really like to not have to type in data for 100+ employees and over 1000 sites, you know?
Thanks in advance.

I'm having trouble converting text to proper text in Access 2010 using Windows 8.1 as OS.
The message I keep getting is:
The expression you entered contains invalid syntax. You omitted an operand or operator, you entered an invalid character or comma, or you entered text without surrounding it in quotation marks.
The formula I use is:
strconv([field],3)

I am using calculated field as a data type in access 2010.
They are working fine.
However, I added a new field and now the final calc won't work.
I have Subtotal adding loads of fields together. Works fine.
Then I have a VATunit field which is a double integer, so enter 20 and my next field is VATTotal calculates the SubTotal + the VATunit by doing (Subtotal/100)*VATunit. This calculation is fine and gives me the correct amount.
The next field is a Total field. Which adds Subtotal and the VATTotal together. Howver, the Total is the same as Subtotal. It is not adding the VATTotal to it?

I have a form with a command btn on it that runs an append query. I am appending data from tble2 to Customer_Order. Customer_Order is a linked table from our MRP application. I'm only trying to append 5 fields right now. They are the fields that are required and won't accept a null in my linked MRP table. However I am getting a Key Violation error. Below is table structure for each table. The OrderID is a combination of 2 fields from a form - would that cause any problems? Any ideas?
tble2
OrderID - text, required
CustomerID - text, required
EntityID - text, required
BuyRate - number, required
SellRate - number, required
Customer_Order
ID - text, required
Customer_ID - text, required
Entity_ID - text, required
Buy_Rate - number, required
Sell_Rate - number, required

im trying to perform an append query, but for some reason cannot due to 'key violations'.
the primary keys in both tables are exactly the same. im trying to append a row from one table to the other without creating additional records.
i can do the append, creating additional records when i remove the primary key from the destination table, but that wont work. and im getting sick of cut and paste.
any thoughts?

I have updated a database I created with additional reports, some UI
enhancements, etc., but have not changed anything about the table structure, field types, etc. The database has been in use for about a week by the user and I was working on my local copy. How do I provide the updated database to the user without incurring key violations on the auto-number PKs when their data is imported into the new version?
