Query Using Two Tables Does Not Return Values For Certain Parame Version: 2002
Oct 24, 2007
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.
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 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 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: 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.
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.
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.
Ok. I have tables vinculate to ORACLE, the primary key of Oracle is double, from Access of query return one number rounding 1,00000902026541907589E+20 this is the problem, in query i have this funtion: IIF(isnull([CAMPO1]);[CAMPO2];[CAMPO1]) this return one number ok field(CAMPO1) and other bad(CAMPO2 it's rounding). I need that return this query two doubles. example:
bad - 1,00000902026542E+20 = 100000902026542000000 ok - 1,00000902026541907589E+20 = 100000902026541907589
I am trying to write a query that will return records from multiple tables. I currently get an error suggesting I create a subquery or else I get far too many records.
The query is EditAttendanceQuery (I left it in a bit of a state). The fields I need are shown in the query. The records I need are based on the Edit AttendanceQuery (Form). I can get the records I need without the CourseNumber and Section, but it all goes downhill when I include them.
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!!
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 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
Maybe someone could help me with this problem. I'll try to expline it....
I have module with function KLookUp(D,M,N) in which is statements like
dim rs as recordset, R as variant
set rs=codedb.OpenRecordset("Select D from M where N;") R=rs!D KlookUp=R
I am also have select query in which one field uses KLookUp function. This query makes error "Invalid argument" :(
Maybe someone knows how to avoid functions like that in queries or maybe someone knows, why query don't like functions in which is statements with .openrecordset?
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.
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.
Hi, I have a problem with one of my query, the query has 2 tables, the secondary field from Table2 is linked to the primary field of table1. The primary field Doesn't allow null Value The Secondary Field does allow null value which means that the Data in table 1 only concern Some of Table2's Data. If I run the query with the two tables I can only see the records with the secondary field with no Null Value. Is it possible to get the query Showing All the records of table1 2 and Table1 even if Table1 has no values?
I am trying to join two tables in a query. One of the tables has only the fullname while another has only the surname (this table is imported from an external database). I need to be able to match the two tables up. Can anyone please suggest how to do this or even if this is possible.
I have two tables that are linked by a key field that I need to export for uploading onto a website database: Chemical Properties Chemical Components key field: ChemicalID
I need help in developing a query or an output report to export the chemicals with their properties and the components from the other table. This may not be as simple as just making a query. Each chemical has 3 or more components and currently they are linked to one chemical.
To make a file to transfer to the online database, the chemical and all the components have to be in the same record. Right now the data exists as each record in the chemical table linked to several records in the component table. I don't know how to program the database to put the linked chemicals and their components on the same record. Has anyone confronted this problem before?
I've made as sample spreadsheet to show how the chemicals and their properties will look in the spreadsheet used to upload the data. Please look at the attachment before commenting.
Hi, not sure if this is possible or the most economical approach but here goes:
I have a lookup table (tblHolidays) with a list of holiday dates (fieldname "HolidayDate") in it.
I need an update query that can check all "StartDate" values on a table called "tblMasterLog" and where this date matches the ones on "tblHolidays", will add 1 day to the "StartDate" and then keep repeating until there are no more dates to change.
I have an append query created to add files to a table from an imported excel file. The table to which I am appending (SubTBL) has a field names Observation. This field is not required. There is a relationship to another table (ObservationTBL) which has 3 records. The information I am trying to append includes 7000 records, about 4000 have observations assigned and they match the information in the ObservationTBL. The remaining 3000 have blank records for observation. When I run the append query, only those with observations are appended. The rest are not added because of "key violations". I removed the relationship between the ObservationTBL and the SubTBL and the append query runs. Then when I try to re-do the relationship it fails "Violates referential integrity rules".To be clear:
1. The records without an observation are blank. (There are other fields in this append that have blank fields also and they are not causing any problems) 2. The field observation is NOT set to required.
