Queries :: Query To Determine If Records Already Exist In Table?
Jan 26, 2014
I have a file that I want to import on a daily basis and append to an existing table in my database. The date changes each day. I want to create a query that checks to see if the date (of the first record) already exists before I import and append the new file. If it does, I want to show a message saying something to the effect of "This file has already been imported".

Hello all
I had a query which was working fine to tell me the number of weekend bookings for holiday parks for a specified year:
SELECT Bookinfx.[Park Name], Month([Start Date]) AS FilterMonth, Year([Start Date]) AS FilterYear, Count(Bookinfx.[Park Name]) AS Bookings
FROM Bookinfx
GROUP BY Bookinfx.[Park Name], Month([Start Date]), Year([Start Date])
HAVING (((Year([Start Date]))=2005));
However it has become necessary to only find bookings of specific accommodation types so I modified it like so:
SELECT Bookinfx.[Park Name], Month([Start Date]) AS FilterMonth, Year([Start Date]) AS FilterYear, Count(Bookinfx.[Park Name]) AS Bookings
FROM Bookinfx
WHERE ((Bookinfx.Day)="FRI" Or (Bookinfx.Day)="SAT") And ((Bookinfx.Nights)<=3) And ((Bookingfx.[Accom Type])="CHALET/LODGE" Or (Bookinfx.[Accom Type])="STATIC VAN")
GROUP BY Bookinfx.[Park Name], Month([Start Date]), Year([Start Date])
HAVING (((Year([Start Date]))=2005));
Now when I run this, the first problem is that it asks me for the accommodation type, which is odd as I've already specified this in the query. The second problem is that if I enter say 'chalet/lodge' it returns records telling me that there are bookings for chalets and lodges at parks that only have camping! I have trawled through the database to make sure no erroneous records exist and so I know it is a problem with the query.
If anyone can shed any light on what I've done wrong, I would be extremely grateful! :)

Hi Guys!
Need help in putting up SQL string.
I have two tables. The first one contains customer information. Primary key is custno. The second one contains customer logins, primary key is also custno.
What I want to do is to view customer information that does not have customer logins.
Is it possible to do in MS Access 2003?
Regards,
Aga

I have a query that runs just fine and takes about 1 minute to run on average. I have vba code that uses Dlookup to determine if the query returns any records. The problem is that each time it runs it has to crunch all the data, all I care about is if there is any result at all. Is there a way to get the query to stop after it finds one record to speed things up greatly?

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'm using an UPDATE query to update records in one table (tblMain) from another table (tblTemp)
Here is my SQL :
Quote:
UPDATE [tblMain]
INNER JOIN [tblTemp] ON [tblMain].[MainField1] = [tblTemp].[TempField1]
SET [tblMain].[MainField2] = [tblTemp].[TempField2];
I only want to update the records in tblMain which have a corresponding record in tblTemp (linked by MainField1 / TempField1)
If any record doesn't appear in tblTemp, I want tblMain to retain the existing value for that record.
However, it appears that in such situations, the record in tblMain has it's MainField2 value set to null / ZLS.
I've tried using LEFT JOIN and RIGHT JOIN and also tried WHERE clauses but the result is the same every time.

I'm trying to do a query to count corresponding records in another table. It works except for returning zeros. I've tried using NZ and switching the type of join, but to no avail.
Here's what I have:
Query A has 3 columns (FU kids)
AlphaID
DtcCtr (a Location Code)
DlsDtc (a Date of change)
Table A has many columns, but I'm only using a few. (dbo_MNCPSTNote)
AlphaID
DtcCtr (the same Location Code)
ServDate (the date I'm trying to count)
Here's what I have:
SELECT [FU kids].AlphaID, [FU kids].DtcCtr, Count(dbo_MNCPSTNote.ServDate) AS CountOfServDate
FROM dbo_MNCPSTNote RIGHT JOIN [FU kids] ON dbo_MNCPSTNote.AlphaID = [FU kids].AlphaID
WHERE (((dbo_MNCPSTNote.Center)=[FU kids]![DtcCtr])) OR (((dbo_MNCPSTNote.ServDate)>[FU kids]![DlsDtc]))
GROUP BY [FU kids].AlphaID, [FU kids].DtcCtr;
I want to know the count, including zero, of the number of records based on ServDate for each AlphaID in Query A.
I didn't create the tables and have no control over how they are designed/organized.

Hi,
I'm trying to have a button on a form that would delete a record from a table only if there are no child records linked to it.
If there are child records for the selected record, the button would be disabled.
Is there a simple way of doing this?
TIA.

What could cause certain records to not be searchable when performing a search?
I have created a pretty simple Search Form that I can look up a record by a Job#, Phone#, or Name. It populates a list of record(s) on the bottom pane using a split-form.
The issue that I have recently discovered is that some records are not showing up when searched, though the record does exist. I can find the record by manually going to a record in the database that is close to the one I’m looking for and then using the previous and next record button to view the record I want.
So if a record exist and has the relevant data for the field that is being searched, why would it not find it? Using the default search built into Access on the bottom record bar, I can find the record using the search criteria I mentioned above.
I also have the Search Form set that if no search criteria is entered, it will display ALL records. Even with all the records shown, these few records do not show up.
Could these few records have a feature or setting that is disabled that needs changed? If so, what to look for at this point.

I want to run a query on a table that holds all speed information for our trucks imported from a third party. Some of the speed alerts in that table are not correct so we set up a second table managed by the users to enter a speed exception. So if we know that Main St in Dallas TX generates false alerts for speeding we know not to call the driver, the third party db speed limit is not up to date.
So I want my query to pull all the speed data from tblSpeedData, except leave out the records where the street and zip are listed in the tblSpeedExceptions.

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 query which looks up records from a table, now what I would like to do is append the word All Projects to this query - is it possible, and if so how?

I have a query that outputs results like:
Company ID | Data A | Data B | Data C
101 | results |results |results
102 |results |results |results
103 |results |results |results
104 |results |results |results
105 |results |results |results
In another Table containing additional company information, I have the primary key as the company ID, and I want to make the query that outputs the above table, auto-fill the blank fields in the existing Company information with the same headings as Data ABC etc.
However, I don't want the query to add full new records (which I think is the Append Query?), instead I want the existing company records have additional fields (Data ABC) added, with information from the Query added.

I have 2 tables that are joined by a many to many table:
tblProductInfo
- ProductID
tblProductLinerMM
- PLProductID (FK to [tblProductInfo].[ProductID])
- PLLinerID (FK to [tblLiner].[LinerID])
tblLiner
- LinerID
I have a range of products that each use 2 liners. An inner liner and an outer liner. I need to add 2 records per product to the tblProductLinerMM table.
for example
tblProductInfo has the following records:
- 2138557
- 2378954
- 4387657
tblLiner has 2 liners in particular that relate to these products:
- L5475
- L5468
I need to create the following records in tblProductLinerMM preferably with the use of a query :
- 2138557 | L5475
- 2138557 | L5468
- 2378954 | L5475
- 2378954 | L5468
- 4387657 | L5475
- 4387657 | L5468

I have a query with many fields. One of them is the combination of two fields and is called "Components Reference". What I try to do is, every time this query is updated, the records of only this field "Components Reference" to be written to the field of another table which also takes records from an another query. I wish I was clear enough.

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 main form with 3 subforms. Each subform is identical except for the value of the filter property. The filter is for the same field, but with a different value for each subform. So, for example, the first subform has a filter of:
Code:
[WBS Element]="DEF" And [Period]=Forms!frm_ProjectFinancials!Period
while the second subform has a filter of:
Code:
[WBS Element]="PPE" And [Period]=Forms!frm_ProjectFinancials!Period
and the third subform has a filter of:
Code:
[WBS Element]="EXP" And [Period]=Forms!frm_ProjectFinancials!Period
The recordset for each subform results in a single record with numeric values in each field or no records at all. When the resulting recordset is empty (no records), the bound text fields on the subform display as blank. I want these fields to display 0 instead of blank so I can use them in other calculated fields. Functions such as Nz or IsNumeric do not work since there are no records and the values are neither null nor numeric.
How I can display zeroes in the bound fields when no records exist that meet the filter criteria? Or is there a way that I can dummy a resulting recordset to have all zero values when there would otherwise be no records?

I am trying to determine the best method for how to handle this query using Access 2013. I have a clients table that contains the following:
clientID fName lName admissionDate dischargeDate
1 John Doe 05/06/2014 06/27/2014
2 Jane Doe 04/24/2014 05/15/2014
3 Steven Smith 05/15/2014 NULL/Empty
4 Chris Davis 06/12/2014 NULL/Empty
Then there is a WeeklyProgressNotes table that is there for the person that is responsible for auditing the clients charts. It does not contain the actual weeklyprogressnotes, it only contains a Yes/No field and a date field for the date the weeklyprogressnote was completed. Like below:
noteID completed dateCompleted clientID
1 yes 05/08/2014 1
2 yes 05/14/2014 1
3 yes 04/25/2014 2
I am creating a form that the auditor can open to determine what weeks she needs to check for each client to see if they have their weeklyprogressnotes completed that week. The weeks run Mon - Sun and there will be no record in the WeeklyProgressNotes table if she has not yet checked and confirmed for that week. So the form would basically look like this:
fName lName week completed date clientID(hidden)
John Doe 5/19/14-5/25/14 Checkbox Null 1
John Doe 5/26/14-6/1/14 Checkbox Null 1
John Doe 6/2/14-6/8/14 Checkbox Null 1
John Doe 6/9/14-6/15/14 Checkbox Null 1
John Doe 6/16/14-6/22/14 Checkbox Null 1
John Doe 6/23/14-6/29/14 Checkbox Null 1
Jane Doe 4/28/14-5/4/14 Checkbox Null 2
and so on.......
I have thought about creating an SQL statement to select all of the clients and then creating a function that determines their admission date within the specific week and their discharge date withing the specific week and then create a loop with another SQL statement with a BETWEEN clause for all the weeks and determine if there is an entry in the WeeklyProgressNotes table or not. If not then I would display out the above info. I'm not sure if there is an easier, less search intensive way of doing it. Maybe an SQL query that can cut done on some of the looping.

I am trying to make a crosstab query to filter my records from my table.
Here is the scenario.
I want to make a query that will return me my Rep ID, Rep Name, his Bonus and his GV-Q (another value) based on every month.
Now I make a crosstab query and here is the syntax.
Code:
TRANSFORM First([TBL Qualification Data India].[Bonus Rank]) AS [FirstOfBonus Rank]
SELECT [TBL Qualification Data India].[Rep #], [TBL Qualification Data India].[Rep Name]
FROM [TBL Qualification Data India]
GROUP BY [TBL Qualification Data India].[Rep #], [TBL Qualification Data India].[Rep Name]
PIVOT [TBL Qualification Data India].Period;
This resulted in a column for Rep Number, one column for Rep Name and columns for all the period of Bonus I am going to have., so there are basically 9 columns for this till this month for each month and bonus value shows as values for all these month (period) columns.
Now in this same syntax, I want to have my Rep GV-Q value as well as his bonus to show in the same query, I read and came to know that it's not possible to directly have two values or two column headings in a crosstab query, I must have to make a new crosstab query and then use a normal select query to display records from these two crosstab queries, so I went ahead and made a new similar but with one value field changed crosstab query and here is the syntax for that.
Code:
TRANSFORM First([TBL Qualification Data India].[GV-Q]) AS [FirstOfGV-Q]
SELECT [TBL Qualification Data India].[Rep #], [TBL Qualification Data India].[Rep Name]
FROM [TBL Qualification Data India]
GROUP BY [TBL Qualification Data India].[Rep #], [TBL Qualification Data India].[Rep Name]
PIVOT [TBL Qualification Data India].Period;
Now after this how to make a select query to show the data from these two queries.
I can make a normal query based on these two crosstab queries and manually add all fields and then I would have my result but then after every month I have to manually enter these two extra month details from both crosstab queries to my final query and that's not what I want.
Is there any method to do this by gathering data from these two queries into one and achieve the result I want or if there is any other approach to tackle this.
To explain my database and my need for output, I am attaching few pics to make things easier if I made some mistakes in explaining my problem. It's included in attached zip since I am not able to post images or links.

I need to find all MaintItems which field MIC don't exist in either MIC1 or MIC2. So the only result which I need to see is MaintItem '5100161086' as MIC <> MIC1 Unfortunately I can create query which would approve '5100662734' as well
MaintItem ------MIC------ MIC1 ------ MIC2
5100634036 50000173 50000173
5100662790 50000174 50000174
5100662734 50000145 50000145 50000180
5100662734 50000180 50000145 50000180
5100161086 500001711 50000173
So bottom line I need a query which will display only the row below as MIC doesn't exist in neither MIC1 nore MIC2. Also I will have to deal with much more MICs soon so maybe there is a way to concatenate them and compare, isn't it? 5100161086 500001711 50000173
Attached query is what I got so far, but that displays last 3 rows of table above

I'm trying to make a query to return payroll data, but I'm not sure how to get Access to return 0 where data doesn't exist for a particular month.
For example, imagine this table:
Name MonthHours
John 1 160
John 2 160
Dave 1 160
Dave 2 160
Matt 1 160
How would I get this ouput:
Name MonthHours
John 1 160
John 2 160
Dave 1 160
Dave 2 160
Matt 1 160
Matt 2 0
