The help for junctions says to make a compound key in the junction table, but I don't understand the intructions for this. Do they mean make all three of ID's the junction table PK's or is there a literal "Make a Compound Key"
button somewhere?
Currently, the table has an AutoIncrementing field as the PK and the two FK's copied in from the Primaries (converted from Auto to Number). As a result, I can only make one-to-one relationships to the junction table.
I am trying to enforce referential integrity on tables where a compound key is implemented.
I want to enforce integrity on the DETAIL table so that it can only use an SOR_ID from the SOR table that has a corresponding PhaseID in the HEADER table. Here is my current diagram:
The only solution i can think of at the moment is to build two queries. One which concatenates SOR.PhaseID & SOR.SOR_ID, and another which concatenates HEADER.PhaseID & DETAIL.SOR_ID... and then create a relationship between the two queries.
There must be a much nicer way of doing this though?
In a form named PRODUCTION there are 3 text box for invoice data: xtype, xserie, xnumber
I need valid this data from the INVOICE table, where its key is a compound key (TPINV+SERINV+NUMINV)
I tried with:
Private Sub xnumber_AfterUpdate() Dim searchinv as string searchinv=Dlookup("*","[Invoice]", [tpinv]="& Forms![production].[xtype] and [xserie]= &Forms![production].[xnumber] and "&Forms![xnumber] If searchinv ="" then MsgBox ("Invoice doesn't exist'") Cancel = True End If End Sub
When you create a column chart and then change one of the series to a line, how can you then apply formatting to that line? I've attached a stripped down database showing what I'm trying to do. Series 1 shows individual monthly values (percentages) and series 2 shows the target which is 80% for each month.
The problem is that although I can apply formatting to the column series, I can't see any way of selecting the line series so I can set the formatting I want. I'm using Access 2003, on Win XP Professional, in case that's important.
I'm getting back into Access after retiring and about 10 years of isolation (from Access). I have 2010 version and know that one should avoid duplicate entries and a way to do this is make those fields unique key fields. I have a Customers table and have bounced back between CusID (AutoNumber) and Compound Keys (CusFName and CusLName) as the key fields. The compound keys prevent duplicates but become very hard to work with later in code and expressions. The CusID is preferable from that standpoint, but can't prevent inadvertent entry of duplicate names.
I'm currently working with a form, which is in datasheet view. I have many rows which are combo boxes (yes/no), and the name is rather long. So each line (each row) spreads on to 2-3 pages to the right.What I would like to do is make the namebar, on top of every column, a little bit higher, so the name would be split into two lines, or three. Allowing me to make the width allot smaller.Here is an example of my problem:http://213.213.137.96/~terminal/columns.jpgSo my question is, can I change the height of the column name? Or is there some trick I can use?regardsFrímann Kjerúlf
Would it be ok just to make a copy of the BE file (every so often) rather than to make a copy via code?The user can then just paste over the original if it becomes corrupt.
Hey guys.. I am trying to make my DB into an MDE file however that option which is in Tools > Database Utilities is not highlighted on this particular database. Anyone know why? Thanks!
EDIT - This features seems to be inactive on all atabases on my computer (I haven't tried another computer yet). I am using Access 2000 and running Win XP Hme. SP1.
I'm making my first commissioned database and I can't get my head around auto-lookups.
At the moment, I'm only working with tables because I want everything properly formatted and working at the table stage before I move on to making my forms, queries, reports, and eventually the switchboard.
What I want to do is when I call up a particular ID number in a table which has corresponding data in another table, I want the corresponding data, such as names and phone numbers, to come up automatically within the table.
My database has about eight tables in it and all are linked in someway, either because I need to create lookups, or because they will eventually be subforms.
So what I need is for someone to explain an easy way to get the tables to do what I want. I've looked up the Dlookup function in Access Help but it didn't make sense :confused:
Can someone help me please? I would REALLY appreciate it.
In my form I have the title of a CD which is under the name of 'CD_Title' which is taken from my CD's table and I was wondering how to show it up in a Label so when I flick through the albums the Label changes to the album that it is selected!
Being an Access newbie and all I knew nothing about the maximum number of TableIDs being 2048...really I just found out about TableIDs when the error message popped up. :o Is there a way around this, short of revamping the entire database?
I have a front end/back end app in AccessXP/Sql Server. I have a master version of the front end on my pc, and each user has a copy on their pc. Everything works fine. I wanted to go the last step in securing the project, so I converted to an MDE. Now, on some of the other PC's, any field in a form that has "NOW()" as the default value (unbound fields) displays the #NAME? error.
Any idea why it would work fine in a .MDB, but not in an .MDE?
I have 3 tables with which i want to extract columns from each of them and place them into a new table. The problem i have is that none of the tables share a common member. each table contains the same amount o rows spo when outputted to the new table will match up
SELECT testScreen, Count(ID) AS testCount FROM SERPTestInput GROUP BY testScreen
It returns a count for each testScreen that appears in the table.
Then this query returns the same thing except it joins another table and adds the criteria that the status for the record must be successful.
SELECT testScreen, Count(testID) AS myCount FROM Results RIGHT JOIN SERPTestInput ON (SERPTestInput.ID=Results.testID AND Results.testStatus = 'Successful') GROUP BY testScreen
So both queries currently generate an 8 row table with the first column being the testScreen and the second being a count. I would like to somehow combine the two so I get a three column, 8 riow table. Column 1 would still be the testScreen, column 2 the total count for each testScreen and column 3 would be the successful count for each test screen.
In short, can the above two queries be combined into one?
I have a little problem with making a query and would need your help.
I have the following temporary table that gets filled automatically with 2 records every day:
DATE | TIME | NAME | CODE
The first record will have the DATE, TIME, NAME ( always the same ) and the CODE that can be START or STOP.
What i need, is to put the 2 records from the same day in a single row to get something like that: NAME | DATE_START | TIME_START | DATE_STOP | TIME_STOP | NAME
Until now i was able to make 2 different queries. One can give me the START info's, the other one the STOP info's. My question is if there is a possibility to combine those 2 queries or to make one query to get the result i need.
I have 2 tables: first table has 4 columns: /job code/project1/project2/project3/ job code is some digits, and in next columns are the job description (different for each project).
The second table has /project name/job code/description/working hours/date/
I made the query what shows how many working hours was consumed for each project monthly and my working codes, but I would like to have job descriptions after job code, If its project1 then the description should be taken from first table from the column "project1". Is it possible to do it with query?
