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?
Thanks
same as the title goes, why i can't query those figures greater than 15% only? How am i suppose to query them right?.Here is my database you cant check query1 and query 2. I am using Ms Access 2010.

Is there an efficient way to return a -1/0 instead of some number/0?
A table has 4 outer joins to views that return a value or null depending on if that field represents a Federal lease.
These 4 outer joins work.
The result is a ID_Wells column and 4 columns with any combination of values or Null.
This line of TSQL:
ISNULL(ISNULL(dbo.vRE_FedLeaseType.Fed_Lease_Type, '')
+ ISNULL(dbo.vRE_FedLeaseMinOwn.MinOwn, '') + ISNULL(dbo.vRE_FedLeaseSurfOwn.SurfOwn, '') + ISNULL(dbo.vRE_FedDirHzLease.Expr1, ''), '') AS HasFedLease
This creates another final summary column [HasFedLease] that returns 0 or some number.
For the Rule Engine - 0 is False, any other number is True.
Access links to this SQL View. Is there a quick way with out a UDF to convert numbers > 0 to a -1?
Code:
SELECT dbo.Wells.ID_Wells, dbo.vRE_FedLeaseType.Fed_Lease_Type, dbo.vRE_FedLeaseMinOwn.MinOwn, dbo.vRE_FedLeaseSurfOwn.SurfOwn,
dbo.vRE_FedDirHzLease.Expr1 AS CountOffedLeaseDirHz, ISNULL(ISNULL(dbo.vRE_FedLeaseType.Fed_Lease_Type, '')
[Code] ......
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.
I appreciate your help in advance.
Hi All,
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:
ACCOUNT_ID........START_DATE........END_DATE...... ..COST_PER_UNIT
31308.................01-Apr-07................30-Jun-07.................6.195
31308.................01-Jul-07.................31-Aug-07.................6.304
31308.................01-Sep-07................31-Mar-08.................5.422
31308.................01-Apr-08.................31-Aug-08.................6.304
I need a query (preferrably SQL) that will return the rate a customer should be charged each month, e.g.
31308 / Aug 07 / $6.304
31308 / Sep 07 / $5.422
31308 / Oct 07 / $5.422
etc, etc
I'm using Access 2003 and the rates table contains details of about 2500 customers.
Any ideas would be welcomed.
PS. Can someone tell me how to paste a table straight from Excel into the forum post body???
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?
Hey.
Is there any way to make a field in a record automatically set it self so it's the sum of other values in the record
http://img412.imageshack.us/img412/1677/helphg9.jpg
That's an example what i want to do except i had to manually type in 25. Is there any way to get that so it does that automatically. I am happy to use forms or macros or anything as long as it occurs straight away after the data is inputted and not have to run something or open something up
Thanks in advance
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.
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.
Hi
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.
grateful for any advice

Here is my sample DBA
I'd like to solve this issue
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.
Thanks for your much appreciated help
When I enter a number equal to or over ten million, the last two values get rounded and I don't want them to be. My field is setup as a single, standard, two decimals. When I tested it I typed in 123456789, what I got was 123,456,800.00
enter 9999999 get 9,999,999.00
enter 10000199 get 10,000,200.00
enter 10000001.75 get 10,000,000.00
Single is supposed to handle up to 10^38
I have checked my "Region and Language" settings for the OS (W7) and there is nothing in there about rounding or maximum number size. I would like to leave the data type at single for the space considerations, and because it should work as single.
I am trying to run a query where one field has a Not Equal parameter AND another field has Not Equal parameter (for example, Product Code Not Equal "A" AND Client State Not Equal "NY)
The result of the above query are all records that have Product Code = "A" are missing from the result. I want some of the "A" Product Codes; I just want to exclude the ones where the Client state is NY.
The list of values for each field is too big to state it in a positive way (I would have to list all the other 28 product codes and all the other 49 states).
What am I doing wrong? Thank you in advance for any suggestions.
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.
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!!
Many Thanks.
Frank.
I'm working on a freebie for a day care center.
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.
Has anybody got any guidance for me please?
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 Table as PL2008 and RPT2. Both tables have one column named PTUNID. My goal is to first Group, sum certain Columns in the PL2008 then match PTUNID from this Grouping to RPT2 Table's column PTUNID and then show the results which do not match.
I have written following Qry but what really happenning is its giving me all the results ( match and no match in both tables ) and Sum values are incorrect.
SELECT [PL2008].PTUNID, Sum([PL2008].[Total Hours]) AS [SumOfTotal Hours], Sum([PL2008].[Actual Cost]) AS [SumOfActual Cost], [PL2008].[PRFIELD]
FROM RPT2, [PL2008]
WHERE RPT2.PTUNID <> [PL2008].PTUNID
GROUP BY [PL2008].PTUNID, [PL2008].[PRFIELD];
Any suggesstion
Thanks

I have a table like this
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 do not know SQL nor VBA.
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.
View 13 Replies View RelatedI 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.
Good Afternoon Everybody,
Apologies for imposing on you all but I was wondering whether or not you could help me out??
Would you be so kind as to kind as to show me a practical example of how to incorporate a facility into my attached Database which serves to select an equal ratio of my field “SectionHeadings” such that out of the 30 “random” questions that it currently generates it will provides me on completion with the following:
5 From Set1
5 From Set2
5 From Set 3 …..etc etc
It currently generates the 30 questions that I need without a problem; however it routinely selects any number of one particular type, sometimes more from one subject and less of another.
All subjects headings are of equal importance to me and as a consequence would be very grateful if you could look at what I’ve already done and show me what needs to be done in order to achieve my aim.
I hope my request is possible - Any help you could give me would be very much appreciated. Thank you very much.
Best Regards
CarolW
