Queries :: Select Random Records From Unrelated Tables
Aug 9, 2014
I am fairly new to Access 2013 but am trying to create a query that will select random records from three totally unrelated tables and display the results together as if one table -- think video slot machine wheels. Each table has two fields - ID which is the primary key and NAME. The data in the tables are names of states, names of colors, and types of animals. Each table has a different number of records. My end result is a table that selects X number of random records from each table and displays them side by side like this:
Desired Result:
Animal Color State
cat red Ohio
dog blue Texas
fox green Iowa
I have been able to create three individual queries that will pull X number of random records by using:
SELECT TOP 10 Animals.[ID], Animals.[Name] FROM Animals ORDER BY Rnd(-(100000*[ID])*Time());
SELECT TOP 10 Colors.[ID], Colors.[Name] FROM Colors ORDER BY Rnd(-(100000*[ID])*Time());
SELECT TOP 10 States.[ID], States.[LongName] FROM States ORDER BY Rnd(-(100000*[ID])*Time());
Using the three queries above I get three separate lists. how to make one query that will randomly pull from all three tables and make the display above?
As part of my job, each month I have to select 20 problem report resolutions and grade them on quality. Typically we have about 100 problem report resolutions per month. Is there a way I can use a query to return a random selection of 20?
I have to review 20 reports each month for quality check. I have a query that lists the reports completed within the past 30 days. Is there a way to filter this query to show only 20 random records?
If there is no way to do this, can you suggest some way of doing this so that it's impartial? For example I don't want to select the first 20 of the month because everyone will catch on and wait late in the month to post their report. Normally about 70 reports are completed in a month.
A small issue I was wondering of for a few day . Is it possible in SQL query to SELECT multiple fields from multiple tables ? Example for the question is
Code:
dim my_var as String my_var = "SELECT Emp_FName , Emp_LName , Emp_Adress " _ & " FROM Table1 " _ & " AND Emp_Date_Of_Payment , Emp_Sum_Of_Payment " _ & "FROM Table2 " _ & " WHERE Emp_ID = 3 "
Is this code actually valid in SQL gramatics , and is it usable if passed to a Recordset variable ( rs = CurrentDB.OpenRecordset(my_var) ) ? Just FYI - The two tables are not related and I want to keep them that way (If possible relate their records just via SQL/Vba )
I have a form which allows the user to add new records to a table. After the user had entered all the information into the form, they click a command button to add the record. In addition to adding the new record, my command button runs an query which is supposed to generate a random number between 1 & 1,000,000,000 and update the record ID field with that number.
Here is the formula I have been using in the "update To" now of my query: Int((1000000000-1+1)*Rnd()+1)
My problem is that I keep getting duplicates. You would think that the chances of getting a duplicate number would be pretty small with this large of a range, but I get a duplicate almost every time.
I have tried indexing (No duplicates) the field in the table, but that did not work. When my query generated a duplicate number, the record was just not added to the table.
I also tried a two step approach: 1-Make a table of all in use record ID numbers from my table (tblIdNo) 2-Update new record with a random number that is not in tblIdNo
This was a no-go too
How to build an update query that will update each new record added to the table with a random number between 1 & 1,000,000,000 without any duplicates? This seems like it should be so simple, and I am starting to get really frustrated.
I would prefer to accomplish this through a query/queries (if possible) rather than with 100 lines of code. This database is not for me, it's for another group, and the individuals in this group are totally freaked out by code.
I'm trying to insert 10% of a dataset from dbo_billing into another table Random_Temp. Another form is open when this query is to be ran that passess in the billyear and billmonth... I'm sure it's a syntax issue as I can isolate the random number part and it displays the appropriate data, I just can't re-write it to insert into the other table:
INSERT INTO Random_Temp ( indx, peopleId, audited ) SELECT TOP 10 PERCENT b.indx, b.peopleId, b.audited FROM dbo_Billing AS b WHERE (((b.billYear)=[Forms]![billing]![billyear]) AND ((b.billMonth)=[Forms]![billing]![billmonth]) AND ((b.recertifying)=-1)) ORDER BY Rnd(-(1000*b.indx)*Time());
I have three tables DriversName, Route and Orderlines. My job, if I should accept, is to create a form for the dispatcher to assign a driver and a route to each order. Preferably in a query so I can create reports based on Route and Driver, for the loaders & production, and Driver and Route for the driver.
I have a nice query already built to capture the order lines to be delivered daily, averaging around 800 lines. My problem is relationship. There is no relationship to Orders from either the DriversName or Route tables. Unfortunately the Orders table cannot be added to as the next data download would just remove the fields. I have tried just to slam in the tables in my query but of course I get a repeat data line for every driver name and Route letter.
I need this form to have the dispatcher call up the order by number and have two comboboxes for them to lookup and assign order numbers to Driver and Route. Thanks in advance for any suggestions.
My question is, does someone have a suggestion as to how I could build a relationship of Drivers and Routes to the Order query?
Im a new user to access and I was wondering if someone could tell me if it is possible to put two completly unrelated tables into a form. All I want to be able to do is look at the information from both at the same time without having to switch between forms. Ill apreciate any help you can give. Thanks.
I am trying to design a report that will Give information about down time and work time during the day.
I have three tables that I am trying to query: TimeSheet - Employee name, date, etc.TimeSheetSub - Times worked (related to TimeSheet)Orders - Including Start and Complete dates and timesI want to find out on TimeSheet.Date Between TimeSheetSub.Arrived And TimeSheetSub.Departed how many minutes were worked on an order and how many many were not (Orders.Start And Orders.Complete).
When I try to combine these three tables in a query, though, it either ends with tons of records or doesn't work because the tables are unrelated. I was able to do it by making a subquery for the Orders part, but this will not work to make a report.
Any help on this matter would be greatly appreciated!
I am trying to take similar fields from unrelated tables. both fields contain information about the age of my clients. The tables they are in are unrelated, as they are different types of clients, and therefore can not find anyway to relate the tables. I need to come up with a total number of clients at particular age groups. Meaning i need to know how many clients from both tables are between the ages of 8-20, even though the records have no relation. All i need is a count, i dont need to display the records, i dont need to change anything, I just need to know how many.
Hi all, I am having one table with id from 1 to 50. Now I want to return random records from that table using rnd.The point is that is there any funntion like
Select [id] from tblids where id not in (values) with rnd
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.
I have tried to combine data from 3 different tables (unrelated) to make a new one. However, as I understood I can not do this because these 3 tables are unrelated. In my case my 3 tables are for 3 labs' material requirements. I am planning that each lab will fill a form which directly related to there field and direct to me. That is why I intend to have separate tables for each. However, I want to create a table where I will be able to see all the requirements of different Labs altogether. This new table will be kind of Orders.
My statement below is current returning 4 records. Two of the records have the same GBPAmount value.
RequestID is the Primary Key
Code: SELECT TOP 3 RequestID, GBPAmount, Currency, RequestDate FROM PayRequest WHERE (((Currency)="CAD Canadian Dollar") AND ((RequestDate)>#11/16/2014#)) ORDER BY GBPAmount;
Code: RequestID GBPAmount Currency RequestDate 10207 8.17 CAD Canadian Dollar 03/02/2015 9874 33.82 CAD Canadian Dollar 20/01/2015 11327 109.58 CAD Canadian Dollar 23/02/2015 10495 109.58 CAD Canadian Dollar 05/02/2015
I'm having a problem get a query to select all of the records it should be.
When I filter the source table (200_STANDARDIZED NRGL) to show the data I want to see (PC2 = 6000; GAAP = 02; CGL = 0950, 2735, 2736, 3500 and 3501; STD VENDOR NAME = blanks), I get 33 records.
NOTE: Had to take the PC2 records that were not '6000' out of the dB I've attached in order to be able to send dB bu the PC2 filter is needed in the complete dB.
When I create a select query to the do the same thing, I get either:3 records (when I set STD VEND NAME to Like '') or 30 records (when I set STD VEND NAME to NOT Like '*' ) I've attached the dB - Query 1 is the subject of bullet 1 above and Query 2 is the subject of bullet 2 above.
BTW, the three records that show up in Query 1 are the same records missing from Query 2.
I have a large database filled with customer records. Some customers come one time. Other customers come 50 times at year. I want to find all customers that have records that are less than 30 days apart so I can ultimately see the types of products they buy. How do I write the query?
I attached a picture of a sample database. The 30 day (+/-) field doesn't exist but I would like the query results to build it.
I am trying to get the average of a select group of records within a query. It appears the davg function should give me what I need, however my query returns no results. Here is a sample of my data.
I'm having a bit of a situation with a select query that I set up.
I have two tables, both with a list of serial ID's.
One is table field is formatted like this:
"B0340 13 453423 X" The other is formatted like this: "=B03401345342300"
I wanted a select query that could show me the records in a universal serial like this:
"034013453423"
This leaves out the "spaces", the "B" and the " X". (Couldn't find a way to make Access generate a new field with the serial ID correctly without a query).
So I used the "Mid" expression in a select query and it worked, it showed me the first table in the correct format.I wrote the same "Mid" expression for the other table and it worked too.But, when I ask for the results for both tables in the same query, it shows me much more records than I have(all duplicates). I figured out that when in table one I have 20 records, in table two I have 5 then the query shows 120 results (20 x 5).
While I am not new to Access, I am not well versed in its abilities as far as combo boxes go. What I have is a Form where a combo box allows you to pick from a table records 'record ID #' in order to fill in the data of that record to the rest of the form.What I want to do is use a query to select specific records from this table and allow the combo box to show only these 'selected Record IDs' for user selection.
I have a simple select query on a SQL table from Access. The query is:
SELECT tbl_Orders.OrderID, tbl_Orders.Approved FROM tbl_Orders WHERE (((tbl_Orders.Approved)=0) AND ((tbl_Orders.Completed)<>0)) ORDER BY tbl_Orders.OrderID;
The strange thing is that sometimes it pulls 34 results, and sometimes 38. From what I can tell, it should be pulling all 38.
What can I do to make sure it gets all the records?
So I have a table with around 20,000 records and there is a field which holds a phone number for each individual within the organization, I want to run a select query that counts how many are not in the correct format
The format is 10 digits and it must start with a 0
I want to make a query that results in displaying records that have the same IP-address where the difference in the date/time stamp is within 1 minute. When the date/time stamp is > 1 minute the record can be deleted from the table.
