Updating Oracle Backend Tables From MS Access Forms(dynamically)??
Feb 13, 2007
Hello,
My requirement is this...
I have to use MS Access as front end with ODBC connection to Oracle 9i
DB.
The application(forms) should be able to update, delete ,insert records into oracle tables(backend).
i have a main form,which has some unique id's and other info about the ids and the subform shows several matching id's for that unique id in main form. the user who uses this application should be able to
1) search for the unique id in the main form such that the subform displays all its matches
2) they should be able to select anyone match and say approve(there can only be one match), then that particular record should be updated in the table.IF I USE A CHECK BOX AND IF THEY CLICK ON ONE RECORD AS MATCH,HOW
DO I TAKE THAT RECORD SAY THE ID , NAME ADDRESS AND ALL DETAILS AND UPDATE THE TABLE???
similarly when they select some other record i should give option of deleting other irrelevant matches in the backend table.
the main form and the subform uses the same table as source.updates are to another table, i should also have to put entry into audit table about which record was deleted and which one inserted..
How should i do this?? i am new to MS access .VBA, any help would be highly appreciated!
I have a single form which becomes either readonly or editable or addnew using a circular toggle switch. The toggle switch is activated by a command button and the caption of the command button is used as the display of the mode.
The SetAddModeBt is a separate command button that initiates the add mode. The problem is that various form or field properties when defined on the fly are not stored and they get lost when you open the form again. Look at the code below:
Code: Sub tglEditBt_Click() '------------------------------------------------------------------------------- ' Circular toggle button to change display mode of the form ' ReadOnly - Edit - Add '------------------------------------------------------------------------------- ' On Error GoTo NotFound Dim ForName As String Dim strSQL As String Dim FMode As String
[Code] ....
Here the first two cases fail when executing the last statement saying it is not supported.
I'm trying to link to Oracle through ODBC...everyhting is set up, and I can connect and I can also see the tables..The problem is...there are just toooo many tables in the link window!!!....
Does anybody know how to find the right table you want faster??? Or how to limit the tables that are retrieved from Oracle to just the ones I desire?
I even set up the correct Schemas to just view the tables I want...but It won't work when linking it through ODBC!..All the tables appear over and over again... And the list is just tooo long.
I have written a few solutions in Access (using access 2007). Now I going to create a few new ones for my company. We use Oracle for our main database and was wondering what would be the advantages and disadvantages of using Oracle as my backend while Access is my front end?
Also, should I create the queries in Access or in Oracle?
finally, is there anything I need to do differently?
my database is essentially a questionnaire of around 200 questions. I'm trying to add a 'light' version to it.
I've added a 'include in light verion' tick-box to all the questions and a 'light analysis' tick box on the registration page.
The questions are all genertated via queries pulling out the appropriate ones as required. What I'm tying to do is add to these queries so that if the 'perfomr light analysis' tick box is ticked only those questions that have been indicated as light are included, and if it's not all teh questions are included.
sorry if this q has already been asked, but i couldnt find what im looking for after searching..
i have a main form. there is a combo box that is that is bound to tblSupplierDetails. this combox displays the records stored in tblSupplierDetails fine. now beside this combobox i have a hyperlink that opens a subform called 'subfrmAddNewSuppliers'. this subform works correctly - ie. when details are entered here, they are stored in tblSupplierDetails
my prob is that if the user adds new supplier details via the subform, these details do not appear in the combo box for the user to select when they are returned to the main form.. they appear if the form is restarted
Ive inserted the statesment Me.ComboBoxName.Requery (with ComboBoxName ammended) into the event procedure for After Update for the combobox.
however, with this the new details which are added via the subform are replacing the previously added record - so theres only ever one record in tblSupplierDetails.. can someone pls help me with this?
I have a form, very basic.. it contains more or less an inventory frontend in which users input computer equipment that we carry in our state dept.
To make this very brief, in my form at the end I have an "Additonal Information" textbox in which users can add additional notes, comments, etc.
As textboxes are constrained to 255 characters, I chose to show an additional textbox directly below the Additional Information textbox, with a control source set to =Len([Additional_Information]) to show users how many characters they have typed.
What I'd like to do though, is make this value dynamically update while the Additional Information textbox is still in focus... so far, all I can get it to do is update once a user has tabbed away from the additional information textbox.
A client has had a database in operation for about a year. They requested some updates. I have been trying to figure out an easy way to update table structer with out having the client go into the backend and add a field or two.
I wrote an update program, that copies the table from their backend, and copied it to the updated table and tried to copy it back to thier backend, but since it is in a relationship, it won't let me.
I have a backend-database on a network disk shared by 6 users. All users have a frontend client wich they use to administer the datebase. Everything in the frontend looks ok and they can query the latest data. However if I open up the backend database tables nothing has been updated since the middle of december. If i make a copy of the backend I can open it up and create new posts with ID-numbers that has already been taken by the frontend.
Ofcourse I have doublechecked that the clients are connected to the right backend file (there's only on backend file in the directory).
I have made a link through ODBC to a Oracle table but when I view the table through Access 2003 I don't get the same data, some postings are dubble and others are missing. The number of rows are correct and it is also possible to create reports with a correct result.
I have also created a Form to be able to add and amend posting in the Oracle table, but the result is the same as when I just view the table, missing and dubble postings.
Is it possible to update Access tables through a macro of some sort.
Thing is: I would like to collect a membership list in a table. I will add new members on my database but i would like to update another database to have the same data as me. Especially for this particular table.
I will have a look around (i never used access before) but if there is a tip on where to go and find such a feature would be much appreciated.
I have a table for storing details of share prices relating to specific certificate numbers, so only the £ value and the value date changes when we update (done manually at present).
The updates for different companies are done at different times, hence I cannot just delete and import new data, it needs to be an update to a value from an excel sheet (the excell sheet is downloaded from the web provider in question).
I had thought of using "get external data" to create a new or ad to a new table, then an update query to update the main table from the new one, but again cannot seem to get it to work on the specific certificate numbers.
As you can see I have little knowledge on code etc, and have so far only used macros to automate the application we use, can anyone please help???
Hello all. Hope I describe my problem correctly. :D
I have a near complete database with forms linking to tables. Tables have relationships with keys set to ref. integrity/cascade records.
Here is the problem -
My forms are meant for people to input data into these tables. However, I do not want them to change those keys.
Problem 1) If I set primary/foreign keys to "autonumber" I cannot get the relationships to recognize ref. integrity and the records will not cascade, and will not update.
Problem 2) If I set primary/foreign keys to "double integer" then if someone enters a new record into the forms, it is recorded as "zero" when it should be updating in numerical order (I have 479 records in the database, so the next new record should be 480).
Problem 3) If I change it any other way - from double integer or auto number, the tables do not update at all, or do not update correctly.
What is going on here? I thought creating forms was a fairly simple task - create the form, it is related to the table, update the form, it updates the table. I mean, duh. :confused:
Thanks anyone for your help, because Microsoft's site sux.
I am an Oracle DBA with little to no Access experience so please be kind. :D
As of yesterday a frequent user of Access 2003 (11.8166.8172) SP3 reported that all columns in all rows have the value #Deleted in a number of tables linked back to an Oracle database.
I am not experiencing this problem but I have Access 2007. It is not an option for this user to upgrade.
I've discovered several issues over the web with data type issues/ characterset issues but nothing seems to fix the problem. I've tried the Oracle supplied 11g and 10g ODBC drivers. I've tried the Microsoft supplied ODBC for Oracle drivers.
None of it seems to work and I am out of ideas. Can anyone suggest anything?
The problem wasn't noticed until yesterday so it can't have been happening for long. The problem is occuring in Oracle 10.2.0.3 and 10.2.0.1 databases. There has been no change in the Oracle environment.
There was a windows update recently but we tried uninstalling that and it didn't help.
Ok. I have tables vinculate to ORACLE, the primary key of Oracle is double, from Access of query return one number rounding 1,00000902026541907589E+20 this is the problem, in query i have this funtion: IIF(isnull([CAMPO1]);[CAMPO2];[CAMPO1]) this return one number ok field(CAMPO1) and other bad(CAMPO2 it's rounding). I need that return this query two doubles. example:
bad - 1,00000902026542E+20 = 100000902026542000000 ok - 1,00000902026541907589E+20 = 100000902026541907589
I have linked tables from an Oracle database. I want to run a query to find records that have dates in a defined range. The date field in my linked Oracle table is in the date/time format. When I run my Access query, I only get those records that have a date (and no time) in the field. How can I get all records, even those with a date/time entry?
We have an MS Access 2010 Database that uses Local Tables, External MS Access Tables, and ODBC Linked Oracle Tables (Accessed for Read Only). The unsual issue occurs with the ODBC Linked Oracle Tables.
One of the more important aspects of the project is to modify the ODBC Links to point to upgraded Oracle Database Tables. Up until today, all of the Links had been able to be remediated with a simple refresh and test.
This morning, however, it was determined that one of the Database Tables did not exist in the Schema. Instead, it was an Oracle Synonym for a Table that existed in a different Schema. We believe that we have the proper authorization for access to all of the Schemas involved, and despite this fact, MS Access was unable to link to the Table properly.
I have data that needs to be entered. It is the same data across 3 tables but only for the first three columns, then it is different. I can create a form for one of these but not for all three.
I have a continuous form that is using a select query to populate all of the bound controls. The drop downs and text boxes are displaying the values from the correct places. But, the form is not updating in the places I expected.
The select query that is being used to populate, combines information from 3 tables.'TimeEntries' table (the one that I want records to be updated in). This holds employee ID, and numeric values for Project Name and Project Task.
'ProjectInfo' table (nothing should be updated here). This table holds other details about the project (ex. Project Name) that is used to populate a combo box. 'ProjectTasks' table (nothing should be updated here either). This table holds details about project task (ex. Task Description) that is used to populate a combo box.
The issue I am having is that when records are updated on the form, they are adding records to all 3 tables that are a part of the query, instead of just updating the time entries table.
Record Source (form) = Select Query "EmployeeTimeEntry"
I donot have much information at this time, but siiting in an Oracle fusion meeting, the Oracle reps mentioned they have a product to compete with MSAccess. Of course it runs on Oracle instead. They said Oracle had to come with a competing product because to many Access databases turn into Sql Server databases. That is about all the info. I have right now on this. Thought it an interesting subject however.
I'm just looking for some general views and opinions here and would love to know what people think; advantages/ disadvantages etc.
We have a system of spreadsheets traking various ongoing projects in our organisation which are sitting on 6 different regional servers. This poses a number of problems as you can imagine - no way of collating the data or generating reports centrally. Updates/bug fixes cannot be carried out because it would require chaning each workbook individually and so on and so on.
I am trying to make an argument to create a new Oracle based database or similar which will be held on a central server and accessed through the company's intranet.
What I'm trying to do is compile a list of the possible reasons to do this or not as the case may be. Opinions or arguments for and against would be most welcome.
We use an Oracle base software called Trapeze and Microsoft Access sometime used as a front end to access the Trapeze oracle tables. Due to the possible dangers of allowing the users Access, Is there a way to block the users from changing the oracle tables and only be able in MS Access to create reports and queries? Trapeze's security is antiquated and uses Oracle to validate accessibility. Since a user has to be created in Oracle, with update, delete, read, write, append rights, for Trapeze to work correctly, a user can connect directly to the Db through Access and make changes directly to the data, unless the ability to prevent them from modifying the tables and only create reports and queries that they can save.
