View 1 Replies View RelatedQueries :: Select Query Return (text) Instead Of (Boolean Value)
Mar 26, 2015how to do to return a text for each row (as field value) when a table field contains "1" as value ?
for example i have a table named "products" with a field/column called "promotion". Sometime a product is promotional, so in this case, the "promo" column holds "1" as value.
during a select on products table, how can i do to return "in promotion" (e.g.) if the column "promo" holds "1" for a product ?

Please Look At This Boolean Vs String
Dec 2, 2005I'm working on a software that was developed by someone who left the company. The problem is that the software works for all locations execpt one that is in austria, after debuging I found out that there is a statement in the code that uses boolean true or false, the only way it worked is when I put an if statement with false or true as string, ex: if doc = "true" then
buttom line has anyone faced this problem, I searched microsoft website and they said that some vb engines don't convert boolean to string. Please Please if someone has a clue try to help. Thanks.
Boolean Searches? Possible?
Jun 21, 2005I have a search tool, but right now it is 100% case sensitive in the sense that if i search for "test" and my entry is "Test" it will not return any results.
is there any way to setup so I could say search for "Test" and it would find "test" properly? Or even to the extreme where I searched for "Tes*" and it came back with the "test" entry.
Thanks,
Boolean Type Search
Oct 31, 2007I need to create a user interface that will allow a boolean type search of a field. This would mean item1 AND item2 AND NOT item 3, item1 or item2, item 1 NOT item2, etc.
I've set up a combo box setup with the following script, but I can't figure out how to adjust it to allow the multiples.
Please advise if I should adjust this or try a differenmt interface format for my users.

How To Change To Boolean Data Type??
Apr 17, 2007my teacher asked me to do Access homework to change data type from Text to Boolean. Data in "Owned car" field show as Y or N
17178
so I click on Design View and change datatype of this field from "Text" to "Yes/No" , than when I saved it show a message
17179
When I back to Datasheet view, all data in "Owned car" field change to be "No".
How can I change data type to be Boolean type without deleting my original data??? I want them to show the same as Y or N.
Forms :: Boolean Checkbox Updates
Aug 4, 2013I use a form for changing data. So when the user selects a record from a listbox I fill all fields of the form with the content relating to the selected line in the box. Nearly everything runs as wished.
All updates take place immediately but the Boolean field does not update or better it updates only after I move the cursor over it. Then it is correct. To make it clear, I do not need to press a button or click, I only move the cursor over the boolean checkbox.
I access VBA after clicking the line in the listbox and use the dlookup command to get the right values. Do I need something like a requery for a boolean field ?
Modules & VBA :: How To Check If Boolean Variable Has Been Set
Nov 25, 2014I have an Access 2010 db which has a load of global variables of type Boolean. The values are different for each machine the database is stored on, so I have a linked table to a separate Access mdb. On startup the database opens the linked table and assigns values to each variable.
However I need to differentiate between a valuable value of False and the variable having not been set. As boolean variables default to False, this is a problem. One option is to use data type Variant, but I know this is not efficient. I am considering using data type Byte instead of Boolean, with 1 as False and 2 as True.
Modules & VBA :: ApplyFilter With Boolean And String Data?
Nov 14, 2013I have a form used to gather data around some supplier details, and we have a review check box with Boolean data. I'm trying to establish a filter button to filter un-checked boxes by specific suppliers from a drop-down list.
Although I've been able to run filters on suppliers and the review checks separately, together I get a "Type Mismatch" error. I thought it might be because of the Boolean data type, so I tried converting that to String but get the same issue.
So far what I've created is this:
Code:
Dim Chk1 As String
Chk1 = CStr([RevChk])
DoCmd.ApplyFilter , (" Chk1 = " & Chr(34) & 0 & Chr(34) & "") And (" [Supplier Name] = " & Chr(34) & txtSupplSearch & Chr(34) & "")
Modules & VBA :: Public Boolean Variable Not Retaining Value
Oct 9, 2014I have a backup subroutine which automatically triggers when the front-end is closed down (it just takes the back-end, makes a copy and compacts it).It's driven off a hidden form which I use to track who is connected to the BE at any given time. This form is opened as part of the AutoExec when the FE is opened and writes some basic user info to a table. When the form is closed, it updates the table and fires the backup process before quitting Access.
Part of that user tracking process checks to see if the same user is already connected - either elsewhere (i.e. on a different machine) or on the same machine (i.e. opening a second instance of the same FE) - which is undesirable (and, frankly, unlikely, but not impossible) A brief prompt appears to explain that they can only be connected once, at which point the application is quit (to enforce the rule) This also works fine.
I would add a public boolean variable, set it to True by default, then switch it to False if the same user is already logged on before quitting Access.Trouble is, the variable doesn't seem to be holding its value? Here is the Load event for the tracking form :
Code:
Private Sub Form_Load()
On Error GoTo ErrorHandler
Dim dbs As Database
Dim rst As Recordset
Dim strSQL As String
Call InterfaceInitialise
blnPerformBackup = True
[code]...
For some reason, blnPerformBackup is False every time, even though I set it to True at the very start of the Load event (and it is a Public variable, defined in a separate module where I store all my Public constants and variables)
why it is not retaining its value from the Load event? I've checked and it does get set to True - and when I debug, it remains True - but at runtime it reverts back to False by the time it reaches the decision whether to backup or not?
Reports :: Sorting By Boolean Fields - Print All Different Combination
Feb 20, 2015I have 3 fields Yes/No.

A = no et B et C = Yes
Then

Nom, prenom et adresse.

A = Yes, B=No and C = No
Then

Queries :: Make Boolean (Yes / No) Field With SELECT INTO Sql Statement
Nov 28, 2013I'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?
General :: Database Status Flags (Text / Boolean Or Number)

View 5 Replies View RelatedSetting Some Text As Visible Or Invisible In A Tabular Form Wrt Boolean Field
May 3, 2006Hi there,
I know there have been a good number of questions about visibility in forms already but I couldn't find a solution to my problem (or maybe I just didn't get it).
Basically, I have a tabular form (more than one record displayed at once) and one the field is of the Yes/No type. For each record, I'd like to have a text box that displays 'pending', set as visible if the field value is 'Yes' and set as invisible if the field value is 'No'.
The table is as follows:
id : auto-number
Flag: Yes/No [Yes]
If I use the following code on the Flag button:
Private Sub Flag_AfterUpdate()
Me.pending2.Visible = Me.Flag.Value
End Sub
all the 'pending' text boxes appear and disappear together (instead of just the relevant one).
I thought of using another text box, with the same data source ('Flag') but which would set itself to visible or invisible wrt to its own value but I couldn't find a way to do it.
Any suggestions ?
Thanks in advance !
and many thanks already for the forum and the contributions - it's been extremely helpful, esp. for a beginner.
Reports :: Change Text Formatting Of Control In Report Based On Boolean
Jul 10, 2015I would like to change the text formatting (color, italics, bold etc) of the contents of a control based on a boolean value in the underlying datasource of the report.
For instance, I have a report that generates a "Proforma Invoice" i would like to ability italicize the prices of certain items based based on a boolean value (EstimatedPrice) in the underlying datasource.
Queries :: Convert Boolean Fields To Integers / Blank For Null Values
May 22, 2015I have a query which returns, among other things, a number of boolean fields. In some cases, there will be a genuine True or False value in each of these fields; in others, it can and should be Null (e.g. as a result of a 'failed' LEFT JOIN of some description, where there is no associated record in the joined table which fulfills the criteria)
So something like this :
Code:
SELECT [tblTable2].[fldBooleanField]....
FROM [tblTable1]
LEFT JOIN [tblTable2]
ON [tblTable1].[SomeID] = [tblTable2].[SomeID]
However, I will be writing the result of the query to a text file and here's the problem. I want to show a numeric value for a genuine True / False (i.e. -1 and 0 respectively using the standard boolean conversions in Access) and a blank for any Null values.
So I tried this :
Code:
SELECT CInt([tblTable2].[fldBooleanField]) AS fldBooleanField....
FROM [tblTable1]
LEFT JOIN [tblTable2]
ON [tblTable1].[SomeID] = [tblTable2].[SomeID]
However, currently when I look at the exported recordset in Notepad, I am getting 0's for both False and Null values (and -1 for True)
How I can adapt my query to keep Nulls...null? And convert the genuinely present boolean values to integer form?
Only thing I can think of is to use (untested) :
Code:
IIf([tblTable2].[fldBooleanField] Is Null, Null, CInt([tblTable2].[fldBooleanField]))
But there's a number of boolean fields in there, all requiring the same treatment.
Using Boolean 'and' To Update A Table Based On Values In A Link Table
Feb 24, 2008The attached Access XP file demonstrates my problem. I've included a form to make testing easier.
Each record in the Projects table has one or more linked entries in the Keywordlink table, showing keywords that apply to that record. Each record in Projects has a Yes/No 'Utility' field.
A third table, Keywords, supplies the keywords that the user can apply to records in Projects, using the subform on the main form. The Keywords table also includes a True/False 'Utility' field. I have set this to True for for the first three keywords.
I need a query, a series of queries or some VB code that updates Projects_Utility for all records to True if and only if the record's linked entries in Keywordlink include all of the keywords for which Keywords_Utility is True (a boolean 'and', as opposed to an 'or'). Otherwise, Projects_Utility must be set to False.
In the attached file, with the current settings in the Keyword table, the 'GetSelectedProjects' query should then produce single-row listings for ClientA and ClientF.
I'd appreciate any help you can give me on this. I'm not a programmer, but I can manage a bit of VB code if I have to.
Query In Forms Question (printing A Single Selected Query Record From A Form?)
Oct 19, 2004What is the best way to impliment a query in a form so that the user can view the query records, and have the option to print or save the selected record using command buttons?
I tried subforms but I could not get the command buttons to work in the subform after it went into the form, it wanted to print the entire form instead of the selected record from the subform.
So in a nutshell I have 3-4 queries that are built, and I want to have them show up on my form in a format that the user can scroll through the results and select a single record of the results and then print or save that individual record from the form, if such a thing is possible.
Thanks in advance

Queries :: Join Results Of Unmatched Query With Matched Query To Include Null
Mar 24, 2013I am trying to do the good 'ol sales report (query) to include customers with no sales.
I have a customers table, account number table, sales table & sales (line) detail table. (all linked in that order)
If I run a query to show customers (in the customer table) with account numbers, that works
An unmatched query to show customer without an account number works (but of course the unmatched account number field isn't shown).
How can I get the two two be shown together with the "unmatched" having a null or 0 for their account number?
I am guessing in principle, the resulting solution can be modified to show customers without sales alongside those with sales?
Queries :: Opening Design View Of Append Query Without Timing Out Source Query
Mar 4, 2015In some cases I create pass-through queries and use these in an Append or Make-table query to bring data locally.
All is well and fine until source data changes and the pass-through query runs too long and times out.
If needed, I can extend the timeout value in the Parameters of the pass-through query no problem, but when I try to open the Append or Make-table query in Design view to do the same, the pass-through query is first triggered and then throws the timeout, and I cannot access the Design view of the Append or Make-table
Is there a way to open an Append or Make-table query in Design view without invoking the source query?
UNION Query MS Jet Database Engine Cannot Find The Input Table Or Query.
Oct 28, 2005Hello All,
I'm trying to run a UNION query that joins five queries through a MS WorkSpace into a DAO.recordset in VB. I'm pulling the data from a SQL Server Database through VB in Access. I'm attempting to open a recordset with a query passed to it as a string. The query is below. For some reason, I'm receiving a message: "MS Jet database engine cannot find the input table or query. Runtime Error 3078".
Here's what's puzzling. When I run a single query without any UNION statement, the code finds the table and runs fine without error, but anytime I join two or more queries with a UNION statement in the VB, it gives me the error.
I've executed the same UNION query in both Access Query Builder and SQL Server's Query Analyzer and they work fine in both environments. It's only when I call the query from a DAO.Recodset with VB that it causes this problem. The following is a sample of the UNION query joining two of the five queries. Does anyone have any idea what could be the problem? The following query executes in about 5 seconds so I don't think there's a "time-out" issue. I'm thinking that the UNION statement may be the culprit. Maybe there's another way to approach joining these separate queries? Any help would be most appreciated. Thanks.

Queries :: Export Query To Excel Then Delete Query Data From Table
Nov 20, 2013I am wondering if there is a quicker way to export a query to excel then have the data in that query removed from the original table. (effectively cutting the data from the table and exporting to excel)
I understand that this can be done by exporting the query to excel then running the same query as a delete query to remove the data but I just wondered if this is the most efficient way.
I have experience of VB in excel but currently only use the basic macro builder in Access though if Access VB is more efficient I can easily learn.
