I have a simple SELECT CASE query. I'm not sure how the syntax goes and I want to learn about it.
In the attached file, if you click on "cohort table", you will see the categorization for each unit under "field1".
how will I be able to use a SELECT CASE statement in a query to populate each unit with assigned category?
Does anyone know if its possible to perform a CASE Statement in a SELECT statement in Access and if so what the syntax is? Thanks in advance.

I have two fields in a table (True/False): IsActive and IsDefault
I would like to convert some If...Else...Then statements to a Case Select statement which details what should be done when any of the possible states of the two fields exist.
Semi-Psuedo example in the (subform) Form_Current Event:
With Me
If !IsActive = True And !IsDefault = False Then
Do Something on the Parent form
ElseIf !IsActive = True And !IsDefault = False Then
Do Something Else on the Parent form
ElseIf !IsActive = True And !IsDefault = True Then
Do Something Else Again on the Parent form
Else
Do Something Entirely Different
End If
End With
What blows my mind is the Select Case Expression bit. I can't figure out how to write this. Any help is greatly appreciated.
If I write a select case statement for a field X i.e. 6 to 7 for example will this:1. Select any fields X where the number is greater than or equal to 6 but less than (and not including) 7B. Select any fields X where the number is greater than or equal to 6 but includes decimels of 7 i.e. 7.5 ORC. Select any fields X where the number is greater than or equal to 6 but includes but literally only includes cases where the the whole number 7 appears>I only ask because in an example in a book I am looking at says:Case 10000 to 20000......Case 20001 to 30000I would have through the word "to" means until but not including but in this case the field that equals 20000 would never be selected?
View 14 Replies View RelatedI have a boolean array, foundState(3), whose 4 elements correspond to 4 variables describing conditions that will dictate what action is taken upon closing a form.
There are only 6 possible outcomes for the array, and they can be divided into just 4 cases:
Case {T,T,T,T}
Case {T,T,T,F} OR {T,T,F,F} OR {T,T,F,T}
Case {T,F,F,F}
Case {F,F,F,F}
What the proper syntax would be for this if I'm trying to create a "Select Case" statement for these 4 cases.
I'm trying to do the following.
I have a text box named Last_Check on a form.
On that form load I want to use the following SQL statement to populate that text box.
SELECT TOP 1 tbl_QA_Check_Sheets.Machine, tbl_QA_Check_Sheets.The_Date, tbl_QA_Check_Sheets.Time
FROM tbl_QA_Check_Sheets
ORDER BY tbl_QA_Check_Sheets.ID DESC;
can't get it to work.
Please help with the code below.
I am trying to select a different query based on the selection in the [Product] Field. I have 4 different products and 3 different queries to run. Each product is specific to a particular query.
What I would like is:
When Product 3 is chosen "Query 1" is ran.
When Product 1 is chosen "Query 1" is ran.
When Product 2 is chosen "Query 2" is ran.
When Product 4 is chosen "Query 3" is ran.
As it is set up now it appears that when choosing Product 1 I open Query 2 and when choosing Product 2 I open Query 1, but it is the opposite of that. I get the correct query with this code by choosing Product 1 and the Query that opens is actually Query 1, I don't know what is going on here.
When I open Products 3 & 4 it always opens Query 2, no matter what Query I specify.
Please help me sort this out. I am not very familiar with case select. Thanks

Now, I know that something in the UPDATE statement does not match my select statement.What should my Update Statement be, in order to update all the columns in the joined tables?
I'm trying to do a select statement and put it in a variable which i can then output to a text box. How do I get the value into a variable? I can't seem to get my syntax right
This is what I currently have
Maxvalue = "SELECT MAX[Record Num]FROM Joblog"
I would like to have a table update query populate cells in a field, based on an IIf statement (below), but states that the IIf statement arguments still need to be enclosed in parentheses. I don't understand what the problem is, I have two sets of opening / closing parentheses.
Code:
IIf IsNull (=Mid( [CONTRACTOR_TASK]![TASK_NAME] ,6,6))
When I run the below code I am getting the error "End Select without Select Case" I figured it might be because I have the "End Select" before the "End With" however when I move the "End Select" after the "End With" I get the error "Loop Without Do".

I'm trying to replace a null value with $0.00 for the second field in a query. My first try at the SELECT stmt did not contain any solution for a NULL value. The result was that it skipped the record. I need it to show 0.00 because the field is used in another calculated field.
My SQL:
SELECT tblRecovery.CustID, IF((Sum([tblRecovery.RecAmt]) IS NULL, 0.00, (Sum([tblRecovery.RecAmt]))) AS SumOfRecAmt
FROM tblRecovery
GROUP BY tblRecovery.CustID;
This returns : Syntax error (missing operator) in query expression 'IF(( etc.
After clicking "OK", access highlights AS in the statement. I'm not sure how to deal with the NULL value or fix the error?
what is wrong with the following statements. I'm new to access SQl. This would work in ms sql.
Code:
DELETE from Table1
INSERT INTO Table1(email, productid, datecreated, datesend) values ('adf', 5, '10/10/2012','10/10/2012')
Select * from Table1
I've been using a SELECT INTO statement to import data from a linked text file into a temporary table in Access. Something along the lines of :
SELECT [tblLink].[fld1] AS Field1,
[tblLink].[fld2] AS Field2,
[tblLink].[fld3] AS Field3
INTO [tblTemp]
FROM [tblLink]
(There's an INNER JOIN in there and some Nz / CLng functions but just want to keep it simple...)
Now - I've just realised I also need to create a couple of extra 'dummy' fields in my temporary table (for later on in the show) and I need them to be Yes/No format (will set them to False at first, then run some separate queries later to update them)
I tried this :
SELECT [tblLink].[fld1] AS Field1,
[tblLink].[fld2] AS Field2,
[tblLink].[fld3] AS Field3,
False AS Field4,
False AS Field5
INTO [tblTemp]
FROM [tblLink]
But this sets Field4 and Field5 as Number fields, with each record given a value of 0. What syntax is required in the SQL to make these fields Yes/No rather than Number?
I am building a form that uses list box selections on the form to make a temporary query and open the results in Excel.
It mostly works in just trying to make it more functional.
Currently the listbox that contains the first and last names of the personnel also has a unique shorttext 'number' as a primary key for the table (bad choice in my opinion but I didn't design the database I just have to work with it).
The short text primary key is hidden by an option given in the listbox wizard that let me set that field width to zero but still search on it. This is how I currently build the query's where clause when it involves names. I search the primary key.
I would like to update the names list box based upon which cities and locations are selected (both are multi-select).
Do I need to change how I make the "where" clause to use first and last names or an I use the same query and just hide the USER_ID
The query looks like this
Code:
SELECT DISTINCT t_asset_personnel.LAST_NAME, t_asset_personnel.FIRST_NAME, t_asset_personnel.USER_PHY_ID
FROM t_asset_personnel INNER JOIN t_asset_master ON t_asset_personnel.USER_PHY_ID = t_asset_master.ASSIGNED_TO
ORDER BY t_asset_personnel.LAST_NAME;
And the list box wizard hides USER_PHY_ID
By setting the width to zero
If I make my own query in the City_After_Update()
Can I do something like this
Code:
SELECT DISTINCT t_asset_personnel.LAST_NAME, t_asset_personnel.FIRST_NAME, t_asset_personnel.USER_PHY_ID
.fieldWidth(0)FROM t_asset_personnel INNER JOIN t_asset_master ON t_asset_personnel.USER_PHY_ID = t_asset_master.ASSIGNED_TO
WHERE [forms]![myform]![citylist].[itemsSelected]'obviously more code is needed here this is just for conceptual illustration
ORDER BY t_asset_personnel.LAST_NAME;
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"
Hi,
I am trying to run the following query and getting an error. It looks like its because of the Case Statement.
SELECT Role.RoleID, Objects.ObjectID,
CASE MID(Objects.ObjectName, 4, 2)
CASE 'SR'
0
CASE ELSE
2
END AS AccessType
FROM Role, Objects
WHERE (Role.RoleID > 2115)
Can you give me suggestions plzzz
Thanks,
Hello, I'm attempting to use a case statement in order to select fields from a column that have names and addresses mixed. I'm wanting to select only the fields that contain names. For example some fields start with an address of "1998 Sky Rd" or PO BOX, or Suite at the beginning of the field. I would like to first select all fields with names in the field and then use an update statement to move/switch fields to another column. The only problem is that I can't seem to get this query to work. Please help!!!
Thank you!!!!!!!!!
SELECT address1, name3=address1 as expr1
Case [address1]
When mid([address1],1,1) Like [A-Z] then [address1]
When [address] is null then ""
When [address] = "" then ""
Else 'Null"
End,
FROM Exercise1;
:confused:
Hi everyone, please help, i am in depserate need here. Am i right in thinking nested IF functions are limited to 7 variables, i need to choose from 12, so i need to use something different
it seems like a CASE function could do what i want it to, but i really have no clue where to start, shall i enter this into a query criteria box, or on the form itself ina new field box...??
Can you give a few hints as to what the code would look like, i have two fields, obviously. One is 'lesson_type' and one is 'cost' i want the cost to change depending on what is selected in the lesson type box.
LESSON TYPE ----------- COST
Beginner 1hour ----------- 15
Beginner 2hour ----------- 29
Beginner 3hour ----------- 42
Test Retake 1hour -------- 13
Test Retake 2hour -------- 25
Test Retake 3hour ---------36
Disqualified Retake 1hour -- 25
Disqualified Retake 2hour -- 49
Disqualified Retake 3hour -- 72
Advanced 1hour ---------- 10
Advanced 2hour ---------- 19
Advanced 3hour ---------- 27
Is it possible to do that, change the cost correpsonding to what one is entered in lesson_type...??? And where do i put it??? What do i do with it??
Thanks, dragon2309
I am trying to make a field in a query which displays a date based off of the criteria below. I tried nesting IIF statements but I couldn't get it to work so I tried a Case WHEN statement.
CASE
WHEN [Appfrom] Is Null & [Fundfrom] Is Null THEN "7/7/1999"
WHEN [Appfrom] Is Null & [Fundfrom] IS NOT NULL THEN [Fundfrom]
WHEN [Fundfrom] Is Null & [Appfrom] IS NOT NULL THEN [Appfrom]
WHEN [Fundfrom] IS NOT NULL & [Appfrom] IS NOT NULL THEN "7/7/1999"
END
Here is the IIF statement
IIf(IsNull([Appfrom] And [Fundfrom]),"7/7/1999",(IIf(Not IsNull([Appfrom]) And IsNull([Fundfrom]),[Appfrom],(IIf(IsNull([Appfrom]) And Not IsNull([Fundfrom]),[Fundfrom],"7/7/1999"))))))
Neither one works and have no idea how to fix it. Any ideas would be greatly appreciated. Thanks.
Here is my CASE WHEN statement in SQL. What would the If statement be in MS access?
CASE WHEN LEN(Serial) = 9 THEN Serial
WHEN LEN(CAST(Serial as Varchar(255))) = 8 THEN '0'+Serial
WHEN LEN(CAST(Serial as Varchar(255))) = 7 THEN '00'+Serial
WHEN LEN(CAST(Serial as Varchar(255))) = 6 THEN '000'+Serial
ELSE 'Error'
END
AS NewSerial
Thanks for your help!
hey
Is it possible to use sql case statements in access ?
I have used them in sql server all the time and they are really useful!
I mean statements like this one:
"SELECT iOrderID,dOrderDate,iTotalBeforeVat,iShipTotal,iVa tTotal,iTotal,
CASE sOrderStatus WHEN '9' THEN 'Canceled' END FROM tTmpOrderRpt"
thanks!
I am having problems with my subform. I have a table that has events with dates. When I create a subform with eventnames, it shows up. However, I cannot get the eventdate to populate in the case form.
I have attached the database ...
Can I use a [system number] value stored in a table in a select case?

I have this code in an event property on a report and it is working great. However, I now need to do a second case based on which modules are down. Is it possible to have a select case within a select case? I have the select case for the systems now with in each system I need a select case based on modules?
Dim dbs As DAO.Database
Dim rst AS DAO.Recordset
Set dbs = CurrentDb
Set rst = dbs.OpenRecordset("Select * From YourTable")
While Not rst.EOF And Not rst.BOF
Select Case rst![System Number]
Case 42144
' do this
Case 88754
' do this
Case Else
' do this
End Select
rst.MoveNext
Wend
rst.Close
Set rst = Nothing
Set dbs = Nothing
New at this and need help!
I am trying to calculate a date in the future based on an entered date and the sample falling into one or more categories.
Fields: Start Date, manually entered
Interval, combo box, choice of monthly or weekly
Pull Interval, combo box, choice of Long term, Short Term, or Stressed
Conditions, combo box, choice of 25°C, 40°C, or 60°C
1 Week, calculated field
3 Month, calculated field
What I would like to happen is that when the Interval box is the choice of monthly that the 3 Month field calculates the date 3 months from the start date. Also, if the Interval field is weekly the 3 Month field is to be left blank.
I have managed the Dateadd function to calculate the 3 month date, but do not know how to incorporate the condition of the weekly statement to leave the 3 month field blank.
Also where should I put this, right now I have this calculation in a subform. Would it be best to generate this in a query? and if so how do I set this up?
Also, I need to select that the Pull Interval is Long term that I can only choose the Conditions field, 25°C, Interval field as Monthly, and only calculate the 3 month time point. Same thing with the Short term and stressed Pull Intervals, I want when they are selected to only allow me to look at fields relative to those conditions.
Any help would be extremely appreciated. I have several books and they are not spelling out exactly what I need, and with my limited programming experience I am stuck.
Thanks
