Hi all,
I am creating tables in SQL view in Acess, Have managed to create the tables, but am having a little trouble understanding what to do next?
I have an INSERT statement to add names, addresses etc, but cant seem to get it to work.
I am trying to insert into the SQL view in queries, thats where i have created the tables.
Should i use the same querie view or another one, or simply imput the information manually.

SELECT 'A001', 'Jones B', '12 New Road', '469006', 'HNC34';
this is the statment that i am trying to use:

Hi ,
I have two queries . one to list the data for the current month and the for the pervious month which I used to get a union query. From the union query I created another query which I had put in the report_open as a query def.
It works perfectly well on small databases upto 50 mb but when tested with 70mb databases ,report tabkes 30 minutes to execute and also throws the error"query is too complex"
please advise how I can avoid this error and also speed up the report.
Thanks in advance.
the code under report_open looks like this
Dim MyWorkspace As WorkSpace, MyDB As Database, MyQuery As QueryDef
Dim MySet As Recordset
Dim psSql As String
Dim inputno As Integer
Set MyWorkspace = DBEngine.Workspaces(0)
Set MyDB = MyWorkspace.Databases(0)
inputno = store
psSql = "SELECT DISTINCTROW QryRepCMISUnionLargeMovements.Customer_Name,"
psSql = psSql & " QryRepCMISUnionLargeMovements.CUST_ID, QryRepCMISUnionLargeMovements.CRG_CODE,"
psSql = psSql & " QryRepCMISUnionLargeMovements.CurrLimits1, QryRepCMISUnionLargeMovements.PrevLimits1,"
psSql = psSql & " QryRepCMISUnionLargeMovements.Lim1Var AS Lim1Var11, QryRepCMISUnionLargeMovements.CurrLimits2,"
psSql = psSql & " QryRepCMISUnionLargeMovements.PrevLimits2, QryRepCMISUnionLargeMovements.Lim2Var AS Lim2Var11,"
psSql = psSql & " QryRepCMISUnionLargeMovements.Input_Section"
psSql = psSql & " FROM QryRepCMISUnionLargeMovements;"
MyDB.QueryDefs("a").SQL = psSql
Set MyQuery = MyDB.QueryDefs("a")

I have upto 10 queries which in turn produces 10 reports. Each query has a 'current_year' parameter input by user. Storing 'current_year' value in table and accessing it in queries was an option which was discarded because of the possibility of inner queries using 'current_year' value from a table could slow down the query.
Is there any way to set parameter values for 10 queries in a single stretch. In all the queries parameter name is the same.
Here is a sample query. CURRENT_YEAR is the parameter
===================================
SELECT "1. Candidates in full time Education in Government Schools" as CAPTION,
(SELECT COUNT(CAND) FROM MERGED_TABLE C WHERE C.YEAR = CURRENT_YEAR ) AS CURRENT_TOTAL,
(SELECT COUNT(CAND) FROM MERGED_TABLE C WHERE C.YEAR = CURRENT_YEAR AND C_P='S' AND CENTRE <= 'BW835' ) AS CURRENT_NUM, Round(CURRENT_NUM*100/CURRENT_TOTAL,2) AS CURRENT_NUM_PERCENT,
(SELECT COUNT(CAND) FROM MERGED_TABLE C WHERE C.YEAR = CURRENT_YEAR - 1 ) AS CURRENT_MINUS1_TOTAL, (SELECT COUNT(CAND) FROM MERGED_TABLE C WHERE C.YEAR = CURRENT_YEAR - 1 AND C_P='S' AND CENTRE <= 'BW835') AS CURRENT_MINUS1_NUM, Round(CURRENT_MINUS1_NUM*100/CURRENT_MINUS1_TOTAL,2) AS CURRENT_MINUS1_NUM_PERCENT,
(SELECT COUNT(CAND) FROM MERGED_TABLE C WHERE C.YEAR = CURRENT_YEAR - 2 ) AS CURRENT_MINUS2_TOTAL, (SELECT COUNT(CAND) FROM MERGED_TABLE C WHERE C.YEAR = CURRENT_YEAR - 2 AND C_P='S' AND CENTRE <= 'BW835') AS CURRENT_MINUS2_NUM, Round(CURRENT_MINUS2_NUM*100/CURRENT_MINUS2_TOTAL,2) AS CURRENT_MINUS2_NUM_PERCENT,
(SELECT COUNT(CAND) FROM MERGED_TABLE C WHERE C.YEAR = CURRENT_YEAR - 3 ) AS CURRENT_MINUS3_TOTAL, (SELECT COUNT(CAND) FROM MERGED_TABLE C WHERE C.YEAR = CURRENT_YEAR - 3 AND C_P='S' AND CENTRE <= 'BW835') AS CURRENT_MINUS3_NUM, Round(CURRENT_MINUS3_NUM*100/CURRENT_MINUS3_TOTAL,2) AS CURRENT_MINUS3_NUM_PERCENT,

I've just started using 2003 and had a query give me incomplete results. One table contains 6 numbers stored as text joined to the corresponding code in the data set table. Both fields are formatted as text. When using the table as criteria I do not get all of the expected records, I had to type in("1000", "2000",...) in order to retrieve all of my data.
Any ideas on what could be happening?
I use the text setting to avoid problems importing the data set which begins life as a csv file.

Hi there
Strange problem, i'm using XP Pro and Access from Office 2003 (both real full versions from work) - and in general use, when the mouse hovers over the 'print' icon (at the top left, undernear file, edit, view, insert, near 'save', 'new', etc), then access will hang for about 20 seconds then snap back into action.
Now, i don't even want to print anything! But every now and again i accidentally hover over it and it's bugging the hell out of me. Everything is updated (but i will check again now).
Anyone know how to make this stop? I tried a quick search but didn't get far.
Cheers!
Edd

Hi All,
I am new to access and this forum, so hello all.
I am trying to build a database to keep records of my bird sightings. As you might have surmised; I am a birder.
I have come to a holt on creating a complex relationship between the Bird Entry From and the table that contains a list of British birds.
In Bird Entry From two of the fields are for entry of the bird name, one field being the Common Name and the other being the Latin Name. They are both drop down lists that contain all the birds from the table, this being done by import data. The table that holds the bird list has two fields One is called Common Name and the other is called Latin Name, this being the same as the filed names in question in the Bird Entry From
This is where I am coming unstuck. What I would like to happen is that when I enter a bird in the Common Name field (either by typing until the bird is auto entered from the drop down or using the drop down to find the bird) it automatically enters the Latin name in the Latin Name field and visa-versa, but I have become very frustrated with trying to do this.
Am I wasting my time? Or is it possible? And if so would anyone be kind enough to tell me how?
Many thanks,
Simon.

As you all know Im not a expert on databases but work in a volunteer basis in a small community area where we have no money for people to do anything for us.
Im proud because I did the other database and its up and working but this one has got me beat.
Im setting up one for the volunteers, which has computer knowledge, any basic training they need, when they are available and what tasks have been set for them.
I need to have a one form which has just their personal details but to be able to put in data on the other forms and it will link back to the volunteers name.
Ive attached what Ive done and Im sure your all going to laugh - but any help would be appreciated

Trying to set up a fairly simple DB. Here is the layout:
tblRoom(roomID, roomNumber, rackOne, rackTwo, rackThree)
tblStudent(studentID, name)
Each student will be assigned to one, and only one, rack. There will be 3 students to one room. One student can only have one room but a room can have many students... I store studentID in the rackOne, Two and Three fields. My problem is when I try and querry for the information so as to display actual names rather than ID's. I'm not sure If my querry is the problem or if I've set the tables up incorrectly. Any insight is much appreciated.

I want to be able to open up the volunteer table and have it show me the movies they have worked on. The movie data table will list who worked it, but the volunteer tables are not.
Any ideas?

at one point in my database I have two tables and for everyone record in one table I may have either 1 or 0 records in the other. How do I express this in access design? Since it's an optional 1 to 1 relationship I guess?

I was wondering if anyone could help me with a query. Basically I am doing (or trying to do) a small database to track childrens progress in my mums primary school. I'm doing this for free as the budget is rubbish for this type of thing and i dont have enough knowledge to ask for payment anyway! I want to get it right from the start and I think if I get the relationships right initially then I can complete the rest of it on my own. I did this at university (normalisation etc) but ive not used it since i left in 2002 and so have practically forgotten everything i ever did.
Basically, the child comes into the school and is predicted a level in maths, reading and writing. Then in the october, feb and july of each of the 2 years they are there, they are given actual assessment levels. They are also given a prediction level at the beginning of year 2.
So far I have one table with student no, surname, first name, gender, ethnicity, year group and SEN(special educational needs) - with the primary key being student no.
This is where I get stuck - do I go for a maths, reading and writing tables and split it that way - or on an assessment basis, so prediction yr1, october yr1, feb yr 1 etc etc. Or is this completely wrong? Am sooooo confused, so any help would be greatly appreciated.
The outcome I want is to be able to query a childs progress, so for example: show children who achieved a 1a in yr1 maths, and then out of those children, who achieved a 2a in y2 maths (as this is the required shift in progress set by government). I really hope that makes sense.
Thanks in advance

I'm rebuilding my database from scratch now that I've learned a bit from the forums about developing a proper database and I want to investigate whether I have the relationships set up correctly, as I seem to be using lot of one-to-one relationship, which most articles say is very rare, and whether I am formulating many to many relationship correctly. Here is a screenshot of my relationship.
If I've understood this correctly, one-on-one is desired if you have a subset of data that is applicable to the main table only occasionally and is dependent on the main table's data. Have I used that correctly?
As for many to many relationship, articles say this is formed by having two one to many relationship linked together in a table. In my screenshot, you can see that tblAdvocacyVisit is the linking table. However, I've set GuestID as a one-one relationship whereas ClientID is one to many relationship, reasoning that since I do need to relate the Guestl Logbook data to Advocacy table for some queries I will be performing later, this will save me some work. I'm afraid that this may compromise RI or something like that. I can simply add a PK autonumber to tblAdvocacy to revert the GuestID as a one-many relationship, but can't see how that would not create more work in queries or so...
Oh, are the lookup tables supposed to be related at all?
TIA.
Edit- Updated the relationship screenshot.

I’m building a database of protein mutants we use in the lab. A lot of analysis is done on these proteins by various people and it’s becoming a bit of a nightmare keeping track of all the information per protein. What we need is a database. I’m getting a reasonable grip on it all I think with the excellent examples I have found on the forum but there are obviously areas that I have great difficulty with. The main problem for now is that many-to-many relationships are involved and I just cannot get them to work properly.
On each protein up to 8 different types of test are performed. To keep things easy I’ll call them A1 (for Analysis1), A2, A3 etc. These are done by different people from a group of 7. I’ve called them O1 (Operator1), O2, O3 etc. Each of the operators can do multiple analysis and the operators overlap. So e.g. O1 might be particularly good at A1, A4 and A7, O2 might be good at A2, A4 and A5, and O3 predominantly does A1, A4 and A6. What it comes down to is that each operator can in principle do each of the analysis so I have to give that option in the database.
What does work (but is not the solution as it introduces 8x duplication of data) is if I have a separate table with operators for each analysis. The same tblOperators is linked 8 times. There must be a way to link each of the analyis to only 1 tblOperators, probably with the use of a linking but I just cannot work it out from the examples I've found here.
Can someone help me on my way please?
Thanks,
Walter
