Converting Data Type In A Query
May 31, 2007
I'm sure this must be an easy one, I haven't used access for years and I've forgot how to do everything.
I'm designing a query based on a linked table which belongs to someone else. Unfortunately they appear to have stored a cost value (eg. 12030.30) as text.
I need to group the table records together and sum the cost value but I can't because its a text data type. Can anyone help me convert the data type within the query so that I can sum the costs, I've tried to build the expression using the cdbl() function but got stuck when it asked me for a parameter.....
Would appreciate the help :)
Thanks
Lloyd
p.s using Access 97....

I want to say update set field1 = field2
But field1's data type is Number and Field2 is Text. (Field1 is fed by a lookup table). Am I doomed to go through the 700 or so by hand, gurus, please?

Query1:
Src: Table1 joined Table2
ID (Type Text)
Title (Type Text)
Remarks(Type Text)
Formatted: FormatTitle([title],[Remarks])
Expr1: InStrRev([Formatted], "~")
public functionFormatTitle(ByVal sTitle as String, ByVal sRemarks as String) as String
'do process code here very complicated an long, but works find in the end
'creates a Multi-String delimited by | (pipe)
end function
The above works, and Expr1 does give an accurate value for the position of a "~" (tilde) in the string Created by the FormatTitle() function.
However, If I put a Criteria >0 on Expr1 it asks for the value of the [Formatted] field as if it was a parameter. If I put a criteria for Formatted: Like "*~*" I get a Data Type Mismatch in Query Criteria
Query2:
Src: Query1
Title (Type Text)
Remarks (Type Text)
Formatted(Type Text)
Exr1 (Type Number) criteria >0
This Query Also produces the Data Type Mismatch in Query Criteria
pardon me, but WTF? If it isn't a STring, than InStrRev() should produce an error, not an accurate response, and if InStrRev() produces a number why can't i compare it to 0 (zero)? This is indubitably messed up that I'm getting this error. There is no data type mismatch, on either of these tests, one is a string and I criteria-limit it by a string operation, the other is a number and I criteria limit it by a number, WHAT IS GOING ON!!!
Thanks

I have vba code that creates the following SQL:
SELECT SubscheduleID, EventID, WeekOrder, DayID, StartTime, EndTime, Priority, CanJoin, PatientTitle, PatientNickname, IncludesPatient, IncludesAftercare, Letter1
FROM [qryScheduleCombinedDetails]
WHERE (SubscheduleID = 1 AND IncludesPatient = -1 AND DuringAftercare <> "AC only" AND (WeekOrder = "All" OR WeekOrder = 3 OR (WeekOrder = 1 AND Letter1 = "XYZ")) AND DayID = 2 AND StartTime <= #8:00:00 AM# AND EndTime >= #8:30:00 AM#);
When I try to run it, I get a "data type mismatch" error. When I put the same code into a query, I get the same error. However, it will run if I delete either condition from within the (WeekOrder = 1 AND Letter1 = "XYZ") pairing. I can't figure why it can run with either of those, but not both together.
WeekOrder is defined as String. Letter1 is calculated as Cstr(Nz(IIf(Letter,"XYZ","ABC"))) within [qryScheduleCombinedDetails], because I wanted to make sure that it would be recognized as a string.

Is it possible to limit the type of data that can be entered in a query that has a LIKE criteria?
( Like [Enter Data] & "*")
limit to two digits or any number of digits, or limit to numbers only or letters only. .

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 receiving an error indicating there is a data type mismatch when running a query named qappInventoryTakeOn.
Data is entered into the Inventory Transaction Form. If the transaction type is "Take On", when the update button is clicked the record will be saved to tblInventoryMovements and then qappInventoryTakeOn should run to update tblInventory, but I keep running into the aforementioned error.

I have an update query for tGLCashAccount where it adds a value from another table with the BeginningBalance to arrive at CurrentBalance.
Here's what it looks like in design view:
Field: CurrentBalance
Table: tGLCashAcct
Update to: [tMakeNewCashBal].[TotalPrice]+[tGLCashAcct].[BeginningBalance]
Here is SQL code:
UPDATE tGLCashAcct, tMakeNewCashBal SET tGLCashAcct.CurrentBalance = [tMakeNewCashBal].[TotalPrice]+[tGLCashAcct].[BeginningBalance]
WHERE (((tGLCashAcct.GLCashAcctID)="102"));
I get the error: data type mismatch in criteria expression when I run it.

I am trying to construct a crosstab that averages a calculated field from a previous query. It is returning a "Data Type Mismatch" message.
The field I am trying to average is a subtraction of dates to find total days. I assume my field is not a number so I have tried to wrap it in CDbl() to change the type.
The formula is
Code:
CASE_DAYS: CDbl(IIf([Actual Close Date]-[Creation Date]>=0,[Actual Close Date]-[Creation Date],""))

I have a products file in csv format including their category, subcat, and brand name.
Now I want to take that file and split it up into 2 tables in Access. One table will contain the product data only: name, description, price, etc, etc - with a primary key (of course) and a category number. The 2nd table will be the categories for each.
The formatting of the categories table needs to be:
Code:Cat ID | Category Name | Parent ID 1 Tools 0 2 Hammer 1 3 Pliers 1 4 Hardware 0 5 Nails 4
Does that make sense?
My real problem with this is finding a suitable number format for the categories. I imported the file as a table, then I run a query on it to get the ID's for each of the category, subcat, and brand, but of course in the above table format I'll end up with duplicates.
Also, how would I then assign the final number to the product itself?

Hello,
I am in the process of converting data from an excel sheet into Access 2000. I know the import procedure, however some of the fields in the Excel sheet have multiple data.
Is there a way to sort out this problem, short of cutting and pasting or re-entering the data? For example one field has the following: Mon, Jan 10,2006, 9AM to 11AM. I want to eliminate this field and create a field each for the day, date, start time and end time.
Thank you

Hi,
I have 2 linked tables, I would like to join these tables in access, however the first table's field is a memo and the second table is a number. I have tried to cint() the field in a query but I get an error message "Explicit conversion from datatype text to smallint is not allowed"
Any ideas how to get around this problem?
Thanks

I have a field in a table that is comprised of mostly numerical data but some records are text.
I want to convert this field to numerical only and make a new field to put the textual data in.
However converting the field will delete the textual data. What is the easiest way to convert the field but save the textual data AND append the textual data to the SAME record that they were in originally in the new field?

I am using the funtion:
Clng([text field]) to convert a text field into a number so that I can link in a query. Because it is an informix database, I cannot change the underlying table format.
When I run the query, the data is showing "Error".
I tried changing the other table to text and linking but it doesn't seem to link properly because the query doesn't work.
Your advice appreciated.

I’m not an expert in Access and hope that someone can help me with my problem. I have about 20 fields of Yes/No data type.
E.g.
StudentID- Tex
Science – Yes/No
Math – Yes/No
Biology – Yes/No
Chemistry – Yes/No
Economics – Yes/No
...
I would like to create a parameter query (without using form combo box) where when I run the query, it would prompt me for the subject name. Let say I keyed in Science, it would list out all the StudentsID who took up Science only (with a Yes) and the other subjects.
Pls help.
Thanks.

I have a problem converting text to a real date value so I can do some calculations. I have a query that brings in data from an external data source. It appears the data is stored in the external table in text format and looks like this:
20050902 15:40:41
I have tried CDate to convert the text to a date/time format, but no luck. Any ideas?

When exporting a table to excel is there anyway to presever the data structure - ie a text field of length 30 will only take text length 30, Interger would only take integer and date would only take date etc, etc ,etc.

Some fool has chosen number for a date column and the date data show up like
8031976
12022001
If I just change the data type back to data, it's going to delete a lot of them.
Is there a way to make the change and preserve my data?
Thanks in advance.

Hi,
Trying to get back into Access after a long time, just need some refreshing :) tips.
I have 2 tables, one of the tables stores titles (mr, mrs, etc). I tried using the 'lookup' data type to link the data from the other table. This however stores the field as a number and causes problems on my form as only a number is shown rather that the text.
What do I need to do to resolve this? :confused:
Thank you.

the second update query identifys by (date of birth) if the person is over 16 a check box identifys if this person is "ticked" as senior.
The results are returned into my main query in two columns, these columns return -1 or 0 for junior or senior.
I need to produce a report that returns J or S (Junior or Senior) is there a way of converting these results to one column and converting the -1, 0 to J or S.
Please see attached file.
