Just had a query in my mind. I have a table master_data with 16 columns. so please tell me which one of the following would less time to execute.
1. select * from master_data;
2. select cust_name from master_data;
From the above example, i am interested to know, does number of parameters selected in the query effect the execution time.
Hi all,
I converted one database from sqlbase to access.
It is so fast in sqlbase. But so slow in access. Taking time to run the query.
I need to make it fast.
Any help please.
:confused:
Hi, I'm new to Access.
I'm trying to do a very simple thing but I can't.
Let's say I sell a lot of cars, every day so I need a database only to collect info about selling. I need a table (SoldCars) which need refers (read: field) to 2 other tables: 1.Constructor and 2.Model, or only to Model (because Construvctor could be redundant). Anyway, when I register a new sold car, I want a menu in which I can find a Model but not after having chosne the Constructor, so when I choose "Ferrari" then I can only find "Testarossa" and "GTO" and choose one of them. Stored field can be Model, because Constructor is implicit. But I need this tip because let's say I sell thousands of cars per day and I want it to be very quick. Please help or I'll die under piles of cars!
Thanks!!!!
HI all.....
I am in need of some serious help and fast!
I'm using Access 2003:
what I need to do is to be able to use a form, which I created already with a sample, 6 fields, table and let the user input the data in the form fields but each time that the user has finished inputting the data, creating a new table with a different name, specified by the user, with the same fields used in the original one!
In more clear terms: replicate the original table every time the user has finished inputting the data, but use a different name that he will choose.
Thank you!!
PS: Be warned that unfortunately it is my first time using access for something so complex (for me).

I have a purchase order form that has a subform embedded. After users have filled up the form, they click on a button that will open up a print preview of a report. The report shows the details of the form they entered. However, all the fields on the parent form that are filled up after filling up the subform are not displayed on the report.
The reason is most probably that they have not been saved yet. How can I solve this problem?
I'v defined an update query as a string in my VBA code.
Then I execute the update query with : CurrentProject.Connection.Execute
however, I want the query out of the code and into the query folder where the other query's are.
How can I execute the query from within the VBA code when I do this ?
Can I execute a query I have stored in my Access database by using ASP from a webpage?
Thanks,

Hi all
I'm stuck on the following SQL statement. It looks OK to me... but there must be something wrong with it because it doesn't execute.
I've tried the runSQL command and I've tried currentproject. connection.execute as well. Both fail to execute... it has to be the SQL string below.
Thanks for any advice.
SQLImportPE = "UPDATE data INNER JOIN data_import ON data.ID = data_import.ID" & _
"SET data.pe1 = data_import.pe1, data.pe2 = data_import.pe2, data.pe3 = data_import.pe3, data.pe4 = data_import.pe4, data.pe5 = data_import.pe5, data.effort_pe = data_import.effort_pe" & _
"WHERE (((data_import.pe1) Is Not Null));"
Hello again!
Does anyone know if it is possible to execute a form daily?? Like a winows scheduled task or something??
The form I need to run daily basically takes the information from one .txt and keeps it into a table.
Thank you!

Can I keep my queries in the C drive and execute it against tables that are in the LAN network drive ? Right now the queries are also in the netowrk drive. So each time when I refresh the data into C drive, I have to import the queries too.
Is it possible to keep the queries in the C drive and execute against data in the netowrk ? Please let me know.
Thanks in advance.
Is there a way to execute two statements in one query in access? I tried the following but received the following: "Characters found at the end of the SQL statment".
Here is what I have in my qryUpdateRecords file:

I'm opening a second database (db2).
Copying the structure of a db2 table to db3.
Populating the table in db3 with a subset of records from db2.
I've gotten as far as opening the db2 and copying the table structure. Can't figure out how to run the query using execute rather than docmd.openquery.
Code:
Dim appAccess As Access.Application
Set appAccess = New Access.Application
appAccess .OpenCurrentDatabase "DbPathString"
'copy the table structure to dbQn, overwrites any previous with same name
[Code] ......
I got the error message cannot execute command after we upgraded from Access 97 to Access 2000. There are multiple users connected to one database on Windows 2000. Some people are able to get access, but there is a good chunk of people that get the error message " Cannot execute Command".
What's going on and is there a solution?
I have a stored query in my db. The query gets the recordcount of all the items in a table.
In my VBA, rather than code a new db conection, set a recordset etc, I want to execute the query using DoCmd
=======
DoCmd.OpenQuery stDocName, acNormal, acEdit
=======
The above line displays the results of the query.
What I really want is to run the query and store the recordCount in a variable - without displaying the results.
Can this be done?
Thanks all
Can anyone help...
I am writing a query in which, amongst other things, I also want to perform a dateadd calculation.
I have the following
expr:dateadd("d", [lastduration], [lastlandingslot])
This fails to run as the expression is too complicated, I suspect this is because a lot of the records will not have a [lastduration] and its therefore null.
I have ran the code below sucessfully.
expr:dateadd("d", 1,[lastlandingslot])
How can I get this to execute only if the [lastduration] is not null??
Tried to search but network is really slow

i am querying two tables TBL_FCST_WKLY which has 29500 records and TBL_ACTUAL_WKLY which has 798222 records.
When i run this query it sites there forever. Is it because i dint optimize my query or is it because the number of records is too much for access? can someone help plz.
thanks
Because my tables were already large I split them up by environment to speed up data maintenence and retrieval. Thus I have table names which contain the environment as part of the table name (ex: tbl_TEST_MyTable, tbl_PROD_MyTable). Once the user sets the environment they want to use (by clicking on an option button) I update the form's recordsource to the appropriate table. My form has 5 subforms within it.
Even with the split loading the form was taking a long time because some of the queries the subforms are based on are joining tables so that they can be linked (parent/child) to the form. I created indexes to speed up the data access which helped a little but it was still running too slow. So, I attempted to change the subform's queries to only join the necessary data by re-creating the queries each time the user changes the form's current record.
For example, what I had originally was taking too long:
SELECT DISTINCT tb.*, pt.CollId, pt.ProgName, pt.QueryNo
FROM tbl_TEST_SysTables AS tb INNER JOIN tbl_TEST_Plan_Table AS pt
ON tb.Name = pt.TName
ORDER BY tb.Name;
and the parent/child link fields are CollId, ProgName, and QueryNo.
This is the change I made:
SELECT DISTINCT tb.*, pt.CollId, pt.ProgName, pt.QueryNo
FROM tbl_TEST_SysTables AS tb INNER JOIN tbl_TEST_Plan_Table AS pt
ON tb.Name = pt.TName
WHERE pt.CollId = 'BATCH_COLLECTION'
AND pt.ProgName = 'PROGRAM1
AND pt.QueryNo = 123
ORDER BY tb.Name;
where the pt fields are changed dynamically each time the user navigates to the next record in the form. This resulted in much faster access time; however I discovered that the form was always displaying the query that existed before the form was opened. I have not been able to figure out how to get the subforms to display the latest created query.
While debugging I discovered that the form's OnCurrent event was being executed 3 times before the form is opened. I don't know what I'm doing that's causing this.
I also discovered that the subform events are executed before the form's events, so I think that's why the latest query isn't being used. I attempted to requery the subform in the form's OnCurrent and OnOpen event, but to no avail.
is there a simple way to get my access form into VB?
I have vb.
do I have to redo everything?
They really should have made it so you could export the form as a .vb or .frm file so you could open and alter it in the real VB!
Grr.. microsoft!
Please say there is a way!
I want to make my form executable. Thanks in advance
I seem to be having a problem opening a file if there happens to be any spaces in the file name. If I open a .pdf no problem acro reader opens it but if it is in word or excell or any other tells me that the file can not be found and seems that only the first part of the file name before a space in the name and the file extention.
example: "Test it.doc" would appear as "Test.doc". somewhere it seems to be trimming the file name.
Got a problem here:
Timer Interval = 5 Seconds
Private Sub Form_Timer()
My code here..
End Sub
The code repeats every 5 seconds, what I want to do is to execute it only once.
Is there a way to run a query, macro, and/or report in the "background". By this I mean in a way that frees up the current operator to do other things in the database while the query, macro, report keep on running?
View 1 Replies View RelatedI am using MS Access 2007 and I am trying, from my VBA code, to execute (or run) a Batch file. Now the batch foile works, but not from my code.
I used to be able to just do this --> Call Shell("S:AccountingAPTex FilesFile List Generator.cmd ", 1) And it would runit. But using this I get a message telling me that it is an invalid procedure call. So upon looking around on the net I found tha ton place said that with MS Access 2007 you need to do this:
Call Shell(Environ$("COMSPEC") & " /c S:AccountingAP1099 ITEMSW9 FolderCorrected 2011 W9File List Generator.cmd ", vbNormalFocus)
But while it does not error out it dooes noting eitheer. What the batch file does, when it works, is produces a list of all the file names in a folder.
I have a list box (1L) in a form (1F) that list member IDs from a table. Then I have a query (1Q) that use (1L) member ID to get data from a table another related table. When I change the 1L and run the query 1Q the results is correct. So I added a new list box (2L) in form 1F that show the results of the query. When I open the form 1F the 2L is populated correctly by the query. Here is my problem. I need to have list 2L update when I change 1L. Here is what I did. I created an On Change event for 1L that has a code Me.2L.Requery, but nothing happens.

The new query is based on and uses expressions from another query. The error message listed the expressions from the query upon which this query was based.

Here is the SQL code, the offending expression in red:
