Queries :: Query For Inserting Random Records Into Temporary Table
Jul 16, 2015
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 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 making a library database program thing... There's an option for the user to view all books on loan.
I have two tables:
Books, which has columns ID*, ISBN, Author, Title, Year, Location BorrowerStorage, which has columns Book ID, Name, Email Address, Desk Number
Book ID in BorrowerStorage is related to the Books primary key.
Now, for the viewing all books on loan, I want it to produce a read only table which contains all the entries from the BorrowerStorage table and the corresponding Title/Author columns (i.e. the records for which the ID in Books column = BookID in Borrower Storage column)...
I want to store a query into a table, which I will delete later on. But somehow it shows me an error: Data type conversion error at the qdf = CreateTableDef assignment line.
Code: Public Sub LF_Query() Dim i As Integer Dim strSQL As String Dim qdf As TableDef
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?
I want to select at random 4 of these records and append them into another table along with some other data that the query will not pick up, in this case Pilot and Month.
I guess I am having to go the VBA route but dont have a clue on how to do it.
Cheers in anticipation.
Andy.
INSERT INTO Assignments ( flightcode, aircraft, depart, destin, pilotcode, [Month] ) SELECT Schedule.Flightcode, Schedule.Aircraft, Schedule.Departure, Schedule.Destination, [pilot] AS Expr1, [MONTH] AS Expr2 FROM Schedule WHERE (((Schedule.Departure) Like "man*"));
Hi! Please, please, please help me! I have created a form that should get Date, Day inputed by a user. Then it must place 8 the same records in the table. Any help will be appreciated Thanks in advance
Hi all, Really, I am very happy to be a member in this great forum with those great members....
I have a form with three text boxes and one button "Submit". This form is build based on a table with three columns. How can I insert records into this table through that form by clicking that button "Submit"....

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.
I'm having trouble with my VBA module.I have a random test generator which pulls records based on a category from my table into a temp table using a make table query. I use the following code:
Private Sub Command2_Click() DoCmd.SetWarnings False DoCmd.OpenQuery "1", acViewNormal, acEdit DoCmd.OpenReport "WrittenExam", acViewPreview, "", "", acNormal Reports!WrittenExam.lblTitle.Caption = "Exam Name" DoCmd.OpenReport "WrittenExamAnswerSheet", acViewPreview, "", "", acNormal Reports!WrittenExamAnswerSheets.lblTitle.Caption = "Exam Name - Answer Sheet" End Sub
My querry makes the table, and then generates two reports (my exam, and the answer sheet). I'm getting an error 3211, saying the temp table is already in use by another process when trying to generate both reports. I used a Macro before, but I have a need for custom report headings, so I'm using VBA.
In the above example student 1234 has a missing record in year 2004 which supposed to be Term2 in the previous year (i.e. 003) and Term2 supposed to be Term1 value in the following year (i.e. 004). Similarly for student 3311
inserting values from a listbox in to a table. I have a table with a field named: PrefReports. This field will hold data from values in a list box that the user selects.
Table: Profiles Field Name: PrefReports Type: Memo
The user utilizes a form to input the values necessary for the query. I then have the query tied to a command button. When the command button is clicked, the query is executed.
How can I take what the user selects in the list box, and insert into my TblProfiles.PrefReports field? When I run the query, all other information makes it to the table except the list box values.
I am looking for a query that will return records from a table that have related records in another table. Opposite to the Unmatched Query Wizard.I have two tables: tblSupplier and tblSupplierProducts.The two tables are related by the field "SupplierId".I need the query to only return Suppliers that have Products.
I am trying to create a database to link to an online auction site (not ebay) and I want to create a query that randomly generates auction end time and auction length for all listings. I have tried int(rnd()) and various versions but can only generate the same number for all fields in the query.
I have a form, has some fields, one of them is the current date, so when the user click (save )button , which make (add new record )to the only table I have the problem that .all fields are inserted in the table , except the current date !! it is a text box ( Now() )!!
I have a load of data in an excel spread sheet that I'm trying to put into an access using Excel VBA (Jet/ACE SQL I think!?). I do this by constructing INSERT INTO strings and looping through my spread sheet. Let's say the primary key is associated with the field [Company] which holds the company names. A simplified version of what I was using (it all works great ) is below:
Code: Set rs = New ADODB.Recordset Set cn = New ADODB.Connection cn.ConnectionString = GetConnectionString() cn.Open cn.Execute strSQL
where strSQL =
Code: INSERT INTO tblTestMDB ([Company], [Date]) VALUES ('BP', '30/09/2012')
Unfortunately, I am having issues with users adding the same company twice. I'd like it to:
- update the existing company info if the company already exists - add the company if it is not already there.
I'm trying to do it in two stages. First an update, then an add. The first part works great :
Code: UPDATE tblTestMDB SET [Date]='21/03/2015' WHERE [Company]='BP';
The second part: (I have tried numerous variations on the syntax):
Code: INSERT INTO tblTestMDB ([Company], [Date]) VALUES ('BP', '30/09/2012') WHERE NOT EXISTS (SELECT * FROM tblTestMDB WHERE [Company] = 'BP');
I find the error messages rather cryptic but they include things like "Query input must contain at least one table or query." or "Missing semicolon ( ; ) at end of SQL statement." (<== No I'm not!?
Is it possible to run a SQL command to update a field within a table with random numbers?
More specifically - random long integers linking back to an ID (autonumber) field in another table?
Background to this is, I have multiple static data tables related to each other by long integer identifiers (autonumbers)
The structure is fine but I haven't been provided with the actual data yet - but for development purposes, I need to work on other functionality which requires that this data be present.
So I want to fill my table with dummy data such that I can go off and work on the remaining functionality, but then just go back and clear it all out once I get the actual data.
I have one 'main' static table, which links back to other tables, which I have already populated with dummy static (i.e. company names, locations etc) Now I want to go into my main table and populate those fields in each record with a random ID. I don't mind doing this field-by-field (there's only a handful) but I've a lot of records in there (~1000) so I'd rather not do this record-by-record.
I'm trying to create a query that generates random numbers for each record, sorts them by that field, then selects the top record. This should randomize the record being selected.
I can use the Rnd([ID]) function which does appear to generate a random number. Problem is that each time I exit the program and come back in, it always selects the same record. When I remove the Top = 1, to show all the records, every row does have a different random number but it does not appear to be sorting by this field.
If I run the query, here is the number I get: 0.98609316349029
Exit the program, restart, and run the query again: 0.98609316349029
If I refresh the query, the second and third time does appear to be random but the first result is always the same. how to generate truly random numbers?
I have a form with many fields and one field has an OnChange event to run an insert query or log an entry in a table about the change. I get insert entry written with everything except one field.The OnChange event code is:
Code: If AddressStatusFld = 2 Then 'If it has changed from Current to Non-Current create a Contact Log entry for this matte If (Val([MatterShortNoFld]) Mod 2 = 1) Then Me.OperatorFld = 16
[code]....
I just can't work out why the record in MatterContactsMade table has a null value for the field Operator.
Hi, I am wondering If I can Sum the value of rows in one field of my Query Table and Inserting that Calculated value into the bottom of the summed Row in the VBA or through Query Design View.
Please let me know, Thank YOU!
Below I have attached the picture of the data that Im trying to sum and insert into a new row that Hopefully can be created through MS access Query.
I would like to create a "global" temp table that can be viewed by all users. The syntax is: Create [TEMPORARY] TABLE tablename (field type)
QUESTION1: When I put the optional [TEMPORARY] in, I get a syntax error... Create [TEMPORARY] TABLE t (ID int) I've tried... Create TABLE [t] (ID int) Is that the same as doing this??? Create TABLE t (ID int)
Can someone clear up my syntax?
QUESTION2: If i can create a temp table when does the table go away? When I close access? Do I have to delete it?
