Hi.
I have 2 queries, one that returns all the project numbers in the db (say 50 projects), and one that returns some of the project numbers (say 30 projects)
I can make a query that combines the 2 queries, and it returns project numbers that are in both queries (30 projects), but I would like the query to return the 20 projects that are in first query, but NOT in the second query.......does this make sense?
I am sure this is fairly easy.......it has just got me stumped!!
I have a query that uses a linked table from an external database and joins it with a table from my database to return records that contain the same values.
Is there a way to return only the records that are present in the external database and not in my db?
I can not seem to work this out in a single query.
I have: tblChildren tblParents tblGuardians
Because so many familes that use day care are fractured, it is possible for 1 parent to have multiple kids but some of them to have a different second parent.
Therefore each parent and each guardian has thier own line and own unique ID in their respective tables.
each child in tblChildren can have up to two Parent IDs (Parent_ID_1 & Parent_ID_2) and up to two Guardian IDs (Guardian_ID_1 & Guardian_ID_2) I've set the data entry form to require at least one parent for each child, but there may not be any 2nd parent or any guardians.
So what I now need to do is create a query, or series of queries, that results with each child on it's own line, with the name of each parent, and each guardian in thier respective fields.
I need an Access query to return the rate at which a customer should be charged. A customer's rate can be set for a period of 1 to 6 months and the customer's rate table could look like this:
I have two tables, TBL_Students and TBL_Email. Each of these tables have a field called Category, which allows multiple values from a list.
Is there a way to return records from TBL_Students where at least one value in TBL_Students!Category = at least one value in TBL_Email!Category.
E.g. If Student A has categories Maths, Physics and Computing;Student B has categories Maths, English and History;Student C has categories Physics and Geography
I would expect: when TBL_Email!Category = Maths,Physics : Students A,B,C to be returned when TBL_Email!Category = Maths : Students A,B to be returned when TBL_Email!Category = Physics,Geography : Students A,C to be returned
I want to return the price from my transactions table for the value '1' in the ID field in this transactions table.
That would be my first field in the query. The next one would be to do a sum of the sellprice field in my 'inventory' table where the buyingID matches a value of '1'.
how to accomplish this? So far, I'm not getting the query to return anything on the relationship.
I have two tables: tblStudents and tblEnrollments. The query I have designed shows the StudentID and counts the number of Enrollments that each student has. I want the students who don't have any enrollments to still show up and have a 0 by their ID. Right now, only the students with enrollments show up in the query results.
Here is my SQL Statement:
SELECT tblStudents.StudentID, Count(tblEnrollments.EnrollmentID) AS CountOfEnrollmentID FROM tblStudents INNER JOIN tblEnrollments ON tblStudents.StudentID = tblEnrollments.StudentID GROUP BY tblStudents.StudentID;
What do I need to do to it to have null values display as zero?
I have a table that has a list of tasks and checkboxes attached to them to be checked once the task is completed. I need to run a query on the table that will only bring me back the tasks with a completion that is false.
Everything that I read online indicates that this is a difficult task for access. Maybe I can accomplish this in SQL view instead of design? If I put false is all of the yes/no fields, the query brings back nothing.
I have a set of devices that are assigned to a truck, on occastion they are moved from truck to truck, I need to be able to track where they are AND where they have been. Here is what I have:
ID (autonumber) GPS ID (number, this is the specific ID to each device) Truck Number (this is the specific ID for each truck Installation Date (Date installed / moved)
I have created a query to show the data I need, I have put them in order based on date.
- I must keep each event stored on the table
Goal:
To show a list of the current location of each device, nothing more.
Stuff. ItemNo Name ImageName 123 Foo 00123.jog 123 Foo 00FOO.jpg 123 FOO FOO123.jpg 456 bar 00456.jog 456 BAR 00BAR.jpg 456 Bar BAR456.jpg ...
I want to do a query to return just one row per unique ItemNo
So the query would return ItemNo Name ImageName 123 Foo 00123.jog 456 bar 00456.jog
I don't care which one it grabs, the first is as good as the last, as they are essentially different names for the same thing coming from different systems.
I know there's gotta be an easy way to do this, but I've tried things like TOP, DISTINCT, etc and none of them work for me.
How to write an expression/criteria in a query that will return only ID numbers with alpha numeric values. Example: My Id field contains both numeric 479621, 680530 and alpha numeric 132NAV100, 174NAV26a values. I want to run the query to return only the alpha numeric values.
I have a checkbox that when checked returns all of the yes values for the column but I want it so that when it isn't checked, it doesnt search for this criteria at all, is there a way of doing this? I tried option buttons too but I wasn't sure of how to go about it.
Trying to run a query where each 4 fields calling a custom function will not just re-run the same custom function over and over again for each field in a single record.
A Function has a huge amount of multiple queries and logic to perform.The Function returns a Integer, Integer, Integer, and optional Integer. Each integer requires a DLookup to lookup a String description value for each individual integer (in each of 4 fields).
The problem is, the DLookup in each column that runs against each of the integers re-run the same function.The result is that a single record, each of the 4 columns returning a single of the 4 values, the complex function is re-run 4 times.
The function is huge, part of a Business Rules Engine. Depending on the Rule-Meta data - it might launch up to a dozen queries and perform logic steps for each record. This is not the ordinary SQL Query.
Imagine if one record (for 1 field) takes 0.1 second to run. By referencing the function in 4 columns, this same function is re-run 4 times (0.4 Seconds) Against 50,000 records - this duplication of re-running the function for each column can really add up.
Possible Solutions: Researched Class Modules - There is a comment that the property Get, Let actually reduce performance. There are huge advantage of code documentation, documentation and centralization.It doesn't claim class modules reduce execution as each propery is returned. It also describes that Class Modules can't be called directly in a Query - unless each property is wrapped in a function.
Function Returns one String with delimiters: e.g 34;54;55;1 This single column goes into a Make Table (runs function one time per record) Then the D-Lookup is run against static local data. This pevented the function from being run over and over across the network linked data.
Final Solution: Eventually, the many hundred lines of VBA code for the Rules Engine will be converted into SQL Server T-SQL Functions on the server.For a Rule Engine development, Access has been great for a rapid protoype development and testing. The TSQL will be a final big step requiring re-coding. It is not currenty my option for the delivery time frame.
I have a query that runs off three tables: These are tbl_contacts, tbl_status, tbl_publications. All contacts have a status but not all will have a publication. The problem is that when i run the query on a status type where none of the contacts for that status have a publication it will return no results, where what I actually need is for it to just return the details of those contacts for that status. The whole query runs off a form with combo boxes.
I have two date fields in a table. I need to find the days between these dates and, if its greater than 7 days, I want to display the record in a report, so far, I have found a hand function that allows me to enter two dates and it returns a long data value representing the number of days in between the two dates. (google "I've developed the following code to count the business days between 2 dates." and its the second one that starts as SOLVED I made no mods to it as it does what i need it to do.
So, i added this to its own module within the data base for use within a query. My test query basically displays the unique ID, the start date and the end date and then displays the values returned from the function. here is the SQL:
SELECT [Main Table].[Unique ID], [Main Table].[Start date], [Main Table].[End Date], (Business_Days_Between([End Date],[Start date])) AS [Days between] FROM [Main Table] WHERE ((([Main Table].[Start date]) Is Not Null) AND (([Main Table].[End Date]) Is Not Null));
When ran, this Query works... However, when I enter a criteria like =2 or > 7, it says data type mismatch. I have even attempted the CInt() function to make sure its formated as int but i continue to get the same error.
I have a subformClientOffers on my frmAllProperties. On the subformClientOffers is a field called Outside Agents. This field allows for multiple values to be selected.
The subfrmClientOffers is in datasheet view.
While the field Outside Agents DOES allow me to select more than one, they post in the field one after another:
Ken Shaw, John Doe, Jane Doe, Harlan Bestlyn
Therefore, the datasheet view of the subformClientOffers causes the field Outside Agents to get very long, much too long to view without scrolling. My client wishes for everything on the frmAllProperties to be viewable without scrolling.
Is there anyway, to cause the field Outside Agents to place a return between each selected name (sort of a wrap text kind of thing)?
One thing I might mention is that the field is a drop down field from tblOutsideAgents. The table itself has First Name and Last Name, but I concatenated that into Fullname on the form, so that when the user opens the drop down they see the entire name. I don't know if that would have any effect on making the 'return' thing work or not.
I can't use this field as a subdatasheet because I already have one subdatasheet attached to the subform to show multiple notes on each Client Offer.
when I open my Quotations form I'd like a set of services to be selected by default, ex: Brush and Pen. So the user only has to input the quote amount
is there anyway to have the form open with a script like: "on open (or on load). in subform SELECT refproduct where product from tblproducts = 1 and also SELECT refproduct where product from tblproducts = 4" Therefore when my main form opens, in the subform I have already Brush on the 1st line selected and pen on the 2nd. My user only has to type the price.
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.
Maybe I've been looking at the monitor for too long but... I need to have a query return data based on a date field or return all dates greater than 1/1/2001 if left blank.
criteria: [Enter date - mm/dd] Or >#1/1/2001#
When I leave it blank it gives me all dates as it's supposed to but when I type a date it does not filter by that date, I still get everything.
I also tried [Enter date - mm/dd] Or Like "*" but it behaves the same way. I know it has got to be easy but my skull may be too thick to let me see it.
I have a report in which a textbox generates numerical values and letter values. I want to...On report load - if textbox = numbers then hide otherwise show if it contains letter values.
I'm using Access 2010. I need to calculate a score based on values selected in a table by looking up corresponding values in other tables. I have a "Project" form to create new entries into the Project table (see Table 1). When I create a new project record, I will select values for the Payback and Need fields by selecting options from a list. The Payback list is pointed at Table 2 and the Need list is pointed at Table 3. In the below example, I created the "ABC" project and selected "1 year" for the Payback field and "Repair" for the Need field. Pretty simple.
Now that I have the "ABC" project loaded to my Project table, I'd like to create a report that will show a "score" for this project. The score should be calculated as follows: Payback Impact + Need Impact. In this example, the score should be 30 (Payback Impact of 20 + Need Impact of 10).
I have the following dataset in a table called NR_PVO_120. How do i pick out a number (which can change but let's say, 6) of UNIQUE OtherIDs without excluding any OtherIDs under any fax numbers?
So, if you pick OtherID from Row7 you then also must pick OtherIDs from rows 8 and 9 because they have the same fax number. Basically, once you pick an OtherID you're then obligated to pick all OtherIDs that have the same fax number as the one you picked.
If the number requested (6 for this example) isn't possible then "the closest number possible but not exceeding" would be the rule.
For example, if you take OtherIDs from rows 1-10 you will get 6 unique OtherIDs but row 10 shares a fax with rows 11 and 12. You either need to take all 3 (but that will raise the unique count to 8, which isn't acceptable) or skip this OtherID and find one with a fax that has no other OtherIDs and that isn't on the result set already. My result of 6 UNIQUE OtherIDs will need to contain ALL OtherIDs under any fax the existing OtherIDs are connected to.
So one solution is to take rows 1-6, 26. Another is to take rows 1-4,10-14.
There will be many possibilities (the real dataset has tens of thousands of rows and the number of people requested will be around 10K), as long all OtherIDs connected to all faxes on the result set are part of the requested number (6 in this case) any combination would do.
A few notes.
1.Getting as close as possible to the requested number is a requirement.
2.Some OtherIDs will have a blank fax, they should only be included as a last resort (not enough OtherIDs for the requested number).
This is for a fax campaign, we need to make sure no fax number is faxed twice, that all people connected to that fax number are contacted under one fax sent.
In Access 2010 I have a Data Entry Form on which I have an unbound textbox in the header that the user can put a default date in. In the body of the form is a bound textbox that records the date and the default value is set as =defaultdatestat (obviously the name of the box in the header).
Problem: The default date shows up perfectly until a value is put in any of the other text boxes.
For further info : If you put values in text boxes default value disappears; if you then push escape the default value reappears when the values in the text boxes disappear.
I have a query with an INNER JOIN and ORDER BY that is working great. Now, using the same JOIN, I need to update values in one table with the values in another. I thought it would be simple until I learned you can't do an ORDER BY with an UPDATE. Is there another way to achieve the same result? If you remove the 'ORDER BY', the statement below doesn't produce an error but the results are not correct:
UPDATE TableA INNER JOIN TableB ON (Left(TableA.CDN,6))=(TableB.CDN) SET TableA.HCC = TableB.HCC WHERE TableB.HCC Like '241*' AND TableB.BBB = 'X' AND TableA.CCC = "1234" AND TableA.HCC IS NOT NULL ORDER BY TableB.HCC, TableA.CDN;
I have several result fields which are all drop down lists. I want each result field's drop down list values to be different depending on the selected value of the Test1 drop down list.I came up with using the .rowsource keyword. My syntax seems to be fine but I'm not getting any values under the result fields when I run the form.Here is my code so far:
Private Sub Test1_AfterUpdate() If Me.Test1 = "Stress Echo" Or Me.Test1 = "Stress SPECT" Or Me.Test1 = "Stress PET" Or Me.Test1 = "Stress MRI" Then Me.Test1Result2.RowSourceType = "Value List" Me.Test1Result3.RowSourceType = "Value List"
I'd like to create a query which will consist of simple SELECT statements as follows:
SELECT [table1].[field1], [table2].[field1], [table2].[field2] FROM table1 INNER JOIN table2 ON ([table1].[fieldX] = [table2].[fieldX]);
The challenge arises b/c instead of joining on equal values, such as the following: [table1] INNER JOIN [table2] ON [table1].[field1] = [table2].[field1]
I would like to join based on equivalencies, such as: [table1] INNER JOIN [table2] ON [table1].[field1] = 34 is equivalent to [table2].[field1] = 2;
I do not know the proper syntax, so this is where I need help. I tried to search online without any success.
