Queries :: MIN (00) Or MAX Value To Return In Same Column

Jun 10, 2015

I am having an issue with a select query as I want one column to show the MAX and "00" value of the same Column. How do I go about having this task completed.

For example, the column has 00,01,02,03,04,05,*1,*2,*3,*4,*5 so I want a query that will return values of "00" and "05" on this example
00
05

Further example, this is what I have now

SELECT qryPR34_UNION.PR34001, qryPR34_UNION.PR34002, qryPR34_UNION.PR34003, qryPR34_UNION.PR34005,
qryPR34_UNION.PR34006, qryPR34_UNION.PR34007, qryPR34_UNION.PR34013, qryPR34_UNION.PR34014,
qryPR34_UNION.PR34098, qryPR34_UNION.PR34099, qryPR34_UNION.PR34100, qryPR34_UNION.PR34101
FROM qryPR34_UNION
WHERE (((qryPR34_UNION.PR34002)>"0") AND ((qryPR34_UNION.PR34003)>"0")
AND ((qryPR34_UNION.PR34006)<"0") AND ((qryPR34_UNION.PR34099)>0));

On the WHERE command, I need field PR34005 to give me the "00" value or the MAX value (on my example the result will have to give me records that have "00" and "05" value assigned on PR34005

Query To Return Record Set Where 1 Column Is Greater Than Another

Jun 29, 2005

Creating a query in Design View, how does one create a query in the "Condition" field that tells the Access to return the record set where the contents of one column is greater than the other?

Table Name=SURVEY_RAW_DATA
Column Name=TOTAL_EXP
Column Name=TOTAL_NX

There are obviously many more columns than those listed above in the table, but these are the two I want to compare. Also the two columns contain numbers.

In SQL I would write it like this:

Select * FROM SURVEY_RAW_DATA
WHERE TOTAL_EXP > TOTAL NX;

Thanks in advance,
Ken

Queries :: Return Value Greater Than The Result Of Another Column?

Jul 10, 2015

Basically in the query I need a Collumn to only output the greatest value that is given within the sub query. If that makes sense?

Eg. Tenancy start date must be the highest date against the date the property was added back to the system - for post development properties.

At present the it's returning previous tenancies from pre development.

Queries :: How To Return Value Based On Row And Column Location

Aug 9, 2013

I inherited a spreadsheet that uses an Index (Match formulate to return a value. I want to use Access to manage the data going forward. I am just starting to build my tables in Access so I have some flexibility and want to do it right. Here is a sample of the data:

KeyEnroll JanFebMarAprMay
abc1/2013103521
def3/201300789
ghi5/201300008

So if Enroll date starts in Jan I want the 10 amt returned from the Jan column. If the Enroll date starts in March, for that client I want the March amy returned, etc.

results: for client "DEF" the amt returned should be "7" because their enrollment date is 3/2013.

Queries :: Select Statement To Return Specific Data From Another Column?

Nov 3, 2014

I was just wondering if this is a possibility to do in one query or if it has to be run from a number of different queries.

I am currently developing a database from scratch for work (with very little Access experience).

The current query I am trying to run, if linked to a number of tables with different information.

What I am trying to do primarily is link stock to a specific "Host Name", "Serial Number" and "Part Description".

In the "Host Name" there is for example - A1-TX10-10001, B1-TX2-10004, C1-TX-10004 - The latter part of the name is a unique identifier number. The first part is the compartment in which the "stock" sits. So you may have all three components (A1-TX1, B1-TX2, C1-TX3) linked to the same unique identifier (10001 for example)

The serial numbers naturally are different for every single one and of course the srial numbers are linked to the "Part Description" - which will read something like....."C1-TX3 Transmitter", "B1-TX2 Combiner" etc.....

When I run the query like this the Host Name (which is also linked to the unique identifier on its own (10001) it returns everything under "A1-TX1-10001"

What I would ideally like to do is write a statement so that if the "Part Description" contains "A1-TX1" it will only return rows that contain "A1-TX1" in the Host Name and the same for "B1-TX2" and "C1-TX3" in the same query.

If "Host Name" contains "A1-TX1" to return "Part Description" to contain "A1-TX1"

Modules & VBA :: Return Rows In Query From Variant Array Return From UDF

Sep 16, 2014

I have a simple UDF that takes a string and returns a variant, which is an array of strings Example Input "Brick Wall" Return value would be a variant array with first element "Brick" and and second element "Wall" Now I have a table with a field of strings, and I want to make a query that returns all the results from the function, one per line.

So if my input table looks like this

[strField]
"kick the ball"
"return the pass"

my query result should looks like this

[Orig] [new]
"kick the ball" "kick"
"kick the ball" "the"
"kick the ball" "ball"
"return the pass" "return"
"return the pass" "the"
"return the pass" "pass"

Last time I had to do something like this I used VBA exclusively, with ADO objects, but I thought a query based solution would be easier.

With my current data the largest return array size my function returns is 27 elements but I wouldn't want to rely on that number being fixed.

Memo Datatype And DAO

Sep 21, 2006

Hi all

I've posted this in my usual Excel forum without any response so I figure someone here might be able to help. I'm using an SQL query in an Excel VBA macro to extract info from an Access table and dump it into an Excel worksheet, which works fine except for a Memo field, which is truncated to one character length - text fields are fine, just this one Memo field. I'm using the Microsoft DAO 3.6 library. Any ideas?

Cheers

Parameter / Datatype

Feb 28, 2008

I have a bunch of queries put in 1 macro. Of course, some queries have the same parameter [Enter current monthend] so when I run a macro, there are few popups asking to [Enter current monthend]. It’s annoying for users to put in the same parameter 2 or 3 times for a report. Is there a way to avoid it?


I tried to make [Enter current monthend] as a new_field so the 2nd query could pick up new_field instead of [Enter current monthend] again but that gave me an error b/c the new_field automatically has ‘binary’ datatype instead of ‘date’ datatype. How can I fix this?

Thanks.

Automating A Datatype Change

Feb 1, 2006

When I export or do a make table query from Oracle to Access, the new table has some of the datatypes changed. Many of my numberic fields are decimal instead of Long Interger. I then need to go and manually cahnge them back. If I forget or miss one, it crashes another application we use.

Has anyone come up with a solution to automatically go through the table structure and change the datatype from one format to another? This would be a great help.

I am using Oracle 9i and Access 2002.

Thanks for you time

Queries :: Using Recordset In VBA Code With Yes / No Datatype

Apr 18, 2013

I'm a having a problem with a Yes/No datatype. Fundamentally, my code looks like this:

strSQL = "SELECT * FROM tblAddresses " & _
" WHERE YPID = " & Me.Parent.IDNUMBER & " AND CurrentAddress = yes"

Set rs = db.OpenRecordset(strSQL)

Now this statement returns 3 records even though only 1 Current Address exists.

false also returns 3 records
true also returns 3 records
no also returns 3 records
-1 also returns 3 records
0 also returns 3 records
1 RETURNS 0 records!!

If I look at the table in Access, I only have 1 CurrentAddress record for my IDNumber.

Tables :: Changing A Datatype Into A Number

I try to export it into an excel file and change all the field that i need to be a number and convert them into a number and it work by when i import them back into access they don't change.

Search On ID / Datatype Problem (GIS Linked Database)

Dec 7, 2005

Dear All,

I have a property database linked to ArcView 3.1. It has a field that links to the ArcView Database called ID which is unique and set to a data type of double.

I have a further form that can go straight to a record if you know it's ID.
This form works fine so long as the ID field is no more than 5 digits. I have a series of polygons that have six figure ID's - the link to arcview works fine using these six fig ID fields however the form that looks for that particular ID can't cope with the six figure numbers...

My problem is although I could change all the ID's of the records in the Database so that the search on ID worked (ie five figure id) they then wouldn't match with the overlay in ArcView and I would not be able to link through using code without first changing and matching all the codes associated with the polygons (time consuming)

I did try changing the datatype of the ID field to long integer but still have the same problem. Strange that the search works for five figure IDs and not six.

Does anyone know whether this is a data type error or is it some simple oversight.? I can probably work out some way of changing all the ID fields to five figures but would prefer to keep the six figures as they are used in some pre-printed material as refs

Thanks in advance

Mark

Runtime Error '3464':Datatype Mismatch

Apr 14, 2005

order_id is an autonumber key field form table Orders_table. Is is also selected in the row.source for the form I am using.
ComboOrder_ID is a combo box that looks up the order_id from the table with a SELECT...
... So I think the two should be the same datatype!

When I set the order_id in the combo the event procedure runs I get the following debug error:-
Runtime error '3464':
Datatype mismatch in criteria expression

This is the code for the after event on that combobox:
[code]
Private Sub ComboOrder_ID_AfterUpdate()
' Find the record that matches the control.
Dim rs As Object
Set rs = Me.Recordset.Clone
rs.FindFirst "orders_table.order_id = '" & Me![ComboOrder_ID] & "'"
If rs.NoMatch Then MsgBox "it's the <find> that is broken" Else Me.Bookmark = rs.Bookmark
End Sub
[end code]
Any help is much appreciated
Thx.
Kev.

General :: Datatype And Viewing Images In Reports

Jul 20, 2015

I am building a database in Access 2007 that needs currently includes images and excel files as embedded OLEs. I am aware this is not ideal, but I can't change my employer's mind.

I've been looking in to the Attachment data type but am having trouble deciding if it will work as a substitute for my purposes. I know a variety of image file types can be displayed inside Access on forms and reports, but I can't find anything about displaying the contents of an excel sheet. I read something about using Active X controls to display .pdf images - is there anything similar for Excel?

How To Prevent Datatype Conversion When Importing Tables From Excel????

Feb 23, 2005

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.
