Deleting Matching Records From Another Table
Dec 6, 2005
Hi
Apologies if there is a previous post that answers this - I've looked, but can't find anything that works.
I have two tables with identical structures. tblA contains a subset of the records on tblB, with identical values on all fields except ID. I need to remove from tblB all records appearing on tblA. I thought the following would work:
DELETE tblB.* from tblB
INNER JOIN tblA ON tblB.Field1 = tblA.Field1
AND tblB.Field2 = tblA.Field2
AND tblB.Field3 = tblA.Field3...
but I get "Could not delete from specified tables".
What am I doing wrong? Or is there an easier way?
Dave

I have two tables "Master List" and "Audit". I want to delete the records from the "Master" that match those in the "Audit". I am using Access 2010 and have used it often but have built very few queries.

Hi,
I've been trying to get this for ages now - both in the design view and in sql:
I have 2 tables - one called DrawingsRegister and a related one called DrawingRevisions. Each drawing has one or more drawing revisions. I want a query that will show each drawing (just once) that has more than one revision:
SELECT tblDrawingsRegister.DrawingNum, tblDrawingsRegister.DrawingName, tblDrawingRevisions.DrawingNum
FROM tblDrawingsRegister INNER JOIN tblDrawingRevisions ON tblDrawingsRegister.DrawingNum = tblDrawingRevisions.DrawingNum
WHERE ((Count([tblDrawingRevisions]![DrawingNum])>"0"));
Thanks for your time,
RCurtin.

Where a many to many relationships is resolved with a linking table...Is it possible to create an entry in the linking table where the two linked tables have the same value e.g. create a entry in the linking table where client table has same value as a job profile table i.e. both are in insurance. Therefore want to create an entry in the middle table with foreign keys from either link automatically

How to get the following results using 1 table:
Field1 ID is an auto record ID, field2 ID is actually field1 ID assigned that record, in other words record 1 has a roommate (record 5) assigned to it, record 2 has a roommate (record 4) assigned to it
Table A
Field1 ID Field2 ID
1 5
2 4
3 6
4 2
5 1
6 8
Results records I'm looking to display for would be:
1 5
2 4
3 6
6 8
I only want to display all fields for records, but I don't want to show their matching record, so I want to display record1, but not record 5 because record 1 has record 5 as a roommate, want to display record 2 but not record 4.

Hello.
I am using a large database, which usually works fine, and is set to compact on close.
Occasionally it has been losing a lot of data in the main table, probably when it compacts, down to a round number of records. This time it left me with 10,000 records exactly. (It has been different round numbers before)
Does anyone have any ideas as to what is causing this?
Thanks.

I have a simple form with a subform on it (see enclosed Access 2000 Database). I'm trying to add/change/delete records from table: Component Name. Adding and changing records is not a problem but deleting is. It only deletes the value of the field "Interative Component Name" and not the entire record. I have my joins defined properly on the tables. What am I missing? I wish this Access stuff was easier to learn. Any help/clues would be greatly appreciated.
Thanks
Sue

I have a training matrix that lists employee names and certifications on various operations. The objective is to choose an operation and run a query to display everyone who is certified on that op. There are additional variables.
Code:
Name EMP ID OP1 OP2 OP3 OP4 OP5
-----------------------------------------------------------------------------
John Doe 526261 C C C
Bob Doe 555622 C C C
Sheila Doe 066600 C C C
Okay that looks about right for the data itself. The listbox has all the ops, you choose an op and hit a button and it goes and finds everyone who has a 'C' in that op column and pulls their record.

I have a form linked to a table and in my form there is a listbox reflecting the records in my table. Evereytime I tick a record in the list box the information on its corresponding columns appears on the text field.
So far I am able to add, modify and save record to my table using this form but I am having a problem on deleting a record which I selected on the listbox. I created a delete command button but it is not working. Please see attached database.

I am trying to create a Delete query.
I am trying to delete a specific part from multiple BOMs in my database.
I have a table of the BOMs that I want to look in. I called this table PartTable. I also linked my database table SYSADM.REQUIREMENT which contains all the requirement parts for all of our BOMs.
So I am wanting to delete only part number 123XX from each of the BOMs in my PartTable.
I am able to select the records with:
Code:
SELECT SYSADM_REQUIREMENT.*
FROM SYSADM_REQUIREMENT INNER JOIN PartTable ON SYSADM_REQUIREMENT.WORKORDER_BASE_ID = PartTable.PART_ID
WHERE (((SYSADM_REQUIREMENT.WORKORDER_TYPE)="M") AND ((SYSADM_REQUIREMENT.WORKORDER_BASE_ID)=[PartTable].[PART_ID]) AND ((SYSADM_REQUIREMENT.WORKORDER_LOT_ID)="0") AND ((SYSADM_REQUIREMENT.PART_ID)="123XX"));
Now how do I delete these same records.
I am getting error saying I have to select a table to delete from....

I have a FrmCadastro which updates my master table TblCadastro. Primary key of the TblCadastro is an auto numbered field named CADID.Fields CPF, NAME, FIN, NAT, TIP, MOT, and INSTREQ of the FrmCadastro are mandatory. My rule is that If any of these fields is null then the record cannot be saved (cannot be added into TblCadastro).
FrmCadastro has two distinct buttons, as follows: BtSave (to save either newly included record or changed record) and BtDelete (to delete a chosen record from my master table).To delete a record has not been a problem because under the click event of the BtDelete I use the following command lines to successfully eliminate an existing record (previously saved) from the TblCadastro:Dim numRecord As Integer
numRecord = Me.CADID
Dim SQL As String
DoCmd.SetWarnings False
SQL = "DELETE * FROM tblcadastro WHERE cadid = " & numRecord
DoCmd.RunSQL SQL
DoCmd.SetWarnings True
To save a complete record (properly filled in) has not been a problem either since the code takes care of that very well.When the user is in the process of adding a new record through the FrmCadastro two different user behaviors can take place:
1. Irregular entering - The user for some reason just give up saving the record (he decides to add the new record later, for instance) by selecting the option Save = No, or
2. Incomplete record - By mistake the user try to save an incomplete record (a record that shows any mandatory field as null).
I coded the following command lines under the click event of the BtSave to take care of deleting those records... BUT it does NOT work. The system reads each line of the code, find the record properly, close the form as expected, but the incomplete record STILL REMAINS in the TblCadastro. I do not understand why, since the code is pretty much the same of the one in the BtDelete.
Code:
Private Sub bt_save_Click()
If MsgBox("The record was changed. Do you want to save it?", vbQuestion + vbYesNo, Me.Caption) = vbYes Then
If MsgBox("WARNING! Incomplete record will be automatically deleted from database. If you did not fill in the fields CPF, NAME, FIN, NAT, TIP, MOT, and INSTREQ, the record will not be saved.", vbOKOnly, Me.Caption) Then
If Not IsNull(CPF) And Not IsNull(Name) And Not IsNull(FIN) And Not IsNull(NAT) And Not IsNull(TIP) And Not IsNull(MOT) And Not IsNull(INSTREQ) Then
[code]...
What should I code to exclude both the incomplete record and irregular entering thru the button Save (options Yes and No) ?

A very elementary question - but I'd be grateful for an answer.
I have two tables (or perhaps two queries) each with a key field. If all is well, there should be complete correspondence between the two sets of records. That is, if there's a record with key 12345 in one table, there should also be a record with key 12345 in the other table.
I'm looking for the simplest way of checking whether or not this is the case, and, if it's not, detecting which records in one table are unmatched by any record in the other.

I have a database called LettersDatabase this databse holds all the letters that have been made including the path to the doc. I use SSN to ID the letters to customers on the Contacts Database.
Contacts database also uses the SSN to id the contacts
I have a form that creates new letters for customers in this form I have listbox that queries the LettersDatabase for all matching records based on the forms contact SSN to see how many letters have been made for that customer.
The problem is that my listbox only shows the first record matching that SSN but there are more records in that LettersDatabase with the same SSN that I need to have diplayed on the listbox as well.
I may be writing the query incorrectly.
Here what I have for the query on the listbox
Like[Forms]![LetterMaker]![txtSSN]
I try adding (&"*") to the end of the query but that does not help.
If anyone out there has the solution to this problem it would be greatly appreciated
Thank you

I need to have the sum of the "matching records" of a subform, exported to a variable of the main form, in order to use it in an if condition.
e.g. "IF a client has brought X? times the vehicle A for a service of type B, THEN do ..."
How do I get the X value in a variable within the main form which presents all activity for all clients (by means of a subform).
I hope this is clear.
Plaese help me, guys. You 've done it before, you're so great!

Hello there,
I have tables like so (simplified):
-=Holiday=-
HolidayID
Name
Date
-=Booking=-
BookingID
HolidayID
ClientID
What I would like to do is create a query which returns a list of all the holidays with a field showing how many bookings have been created for each holiday. This almost works:
SELECT Count(1) AS CountOfBookingID, Bookings.HolidayID
FROM Bookings
GROUP BY Bookings.HolidayID;
...but it does not display holidays where there are no bookings.
Is it possible to create one which will show all holidays even if there are no bookings?
Thanks!:cool:

I have a form where a user reviews information input by another user, once they have done this they sign it off by selecting their name from a drop down list. On this form there is a scrolling message which tells the user how many un-signed entries there are. This works fine until there are 0 (zero) entries to be signed off.
The scrolling message is linked to a count query which basically counts any records that does not have a name entered in the required field. I have done this with ' Not Like "*" '
Like I say it works when there is one or more entries to count, but as soon as there are none the query does not output a zero it is just blank. This is the problem.
I need some sort of statement to say if there are no matching records please display a zero.
Any help would be much appreciated!

I have two tables, categories and items. I have a form that is linked to the categories table and a subform that is linked to the items table. The user selects a category on the main form then an item to add to the category on the subform. (all of this is functioning correctly - but you need to understand for my question.)
Both the form and the subform have a text box that displays a record from their respective table, for the example we will call this color.
What I need to do is create code that checks the color text box from the category (main form) against the text box for the item (subform) and if they are not a match I need to display a message box - from where I can then add the necessary actions.
EDIT: note this is not a query on an entire table or 2 it is just comparing the two text boxes on the form and subform

Suppose I have two tables with fields as follows:
Assigned Courses (Courses that employees should do)Employee number
Assigned Course Name
Fulfilled Course (Courses that employees have done)Employee number
Fulfilled Course
Now I need to do a query that tells me which employees haven't done. Is there anyway to do that that is not an exclude query?
