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?

Dear All,
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.
PLEASE HELP! I'm getting crazyyyyy :confused:

Is it possible in access to link to both oracle AND access tables in the same
access application?
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!
Thanks so much!
Hi,
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.
Any idea what could be wrong?
Thanks
Hi
Can anybody advise me on how to import tables from an Oracle database into Access 97?
In addition to Access 97 I have a copy of SQL+ but don't now how to use it as yet.

Hello,
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.
any ideas?
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
help me...:confused:
My english is bad bad bad... :D
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?
Thanks!
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 made a program in Access with linked tables from oracle (ODBC).
In access when I'm going to use that tables or when I see the records on the table all the numbers with decimals shows without separators (,).
99,99 looks like 9999.
This is a big problem because I'm working with prices.
I tried to change the NSL_Language in Regedit to:
AMERICAN_AMERICA.WE8ISO8859P1
from:
SPANISH_SPAIN.WE8MSWIN1252
AND it works ONLY in my computer, when I try to fix it and change the language doesn't work, and i don't know why.
PD: In addition, in the other PC's, some characters seems wrong like "�" that looks like a square.
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.
Hi guys,
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.
Thanks
Liam
Hello Guy,
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.
hi...

select * from msacees_table@database_link
i am getting the desired result
but when i try to acces a specific column with in the msaccess table like

its says invalid column name....
any idea why its behaving like this ???
thanks...
I was hired to write some reports in Access 2000 for a small company (max of 6 users at a time). The database was created by someone else and he decided that moving to Oracle was the answer to some of their issues (losing data due to record locking). The guy did not know Access at all so that DB is screwed up (another issue all together). I had no problem creating the reports and they ran fine on my home and work computer. When I imported the reports into the Access DB at this company they ran fine (but VERY slow). I then got a call 3 days later from them saying the reports wouldn’t run. The owner decided to upgrade to Access 2003 to see if that would help but that created another set of new error messages. When I try to run the report it gives two messages: "can not perform action/make changes in record primary key" and "record not found". These reports are based on simple select queries. Trying to run the reports freezes the application. I even tried to open the tables and it either freezes the app or takes about 15 minutes to open. These tables are linked to Oracle 8i. The newest OBDC drivers have been installed and the newest Oracle 8I edition has been installed. Since I can run the reports in Access I assume the issue is the link with Oracle. I have very little Oracle knowledge. From what I can tell the data is stored in Oracle and Access pulls the data via the links. Has anyone experienced this? Does anyone know how to fix the issue? Your help is very much appreciated!
Hi,
I'd like to transfer access-queries to Oracle. If I export access-queries, Oracle recognize these as tables and not as dynamic queries? Any idea how to solve this or does anybody know a tool to create queris in Oracle?
Thank!
Tom
I'm using the following tools/systems:
* Oracle 9i Enterprise Edition Release 9.2.0.5.0
* Microsoft Access 2002
* Access is running on a XP Professional desktop
What I'm doing at the moment is:
* Linking the Oracle tables in Access via ODBC
* Using Access to run develop & run queries against the linked Oracle tables
What I'm trying to figure out:
* What is the easiest way to export the query results to a local (on my machine) Access table?
Some of the queries return < 65000 rows, so I can export to excel & import the excel file back into access. Unfortunately this doesn't work for the bigger queries.
Suggestions?
Hi, I have a question regarding improving the performance of an Access front-end linking to Oracle tables.
Basically what I have done so far is migrate around 35 or so tables into an Oracle 9i database. After linking the tables in Access and prototyping some of the existing forms/reports/queries in Access, I noticed that the speed performance of everything was noticeably slower. Any suggestions as to how I can resolve this issue? For read online queries and reports, I understand that I can use a pass-through query to speed things up. However, all the forms need to allow for data entry and based on my understanding, the pass-through query solution would NOT work for this.
Any suggestions? Any help would be appreciated.
I have linked ms access to orcale to run a query, the date in orcale is in this format 20140101, i have tried to convert the date in the query like that but it's not working. format(mydate,"yyyy/mm/dd".
View 3 Replies View RelatedHello to everybody,
I want to access Oracle 8.0 Data (meaning Oracle tables) with Access 2002. My problem is that I do not want to enter the username and password every time I connect to the Access db, as I want to create some queries in Access which I will export to Excel.
I do not think that this is something difficult but I can't seem to find any solution. Is there any proposal?
Hello,
I'm making a MS Access frontend for some tables on the Oracle 8 database at work. The tables are linked ofcourse.
One table has an AUTONUMBER field on the Oracle and it seems to give me trouble to insert new records.
When I try to insert a new record (leave the autonumber field blank) I get the following error: "ODBC — insert on a linked table <table> failed. (Error 3155)" followed by the error "[Microsoft][ODBC Driver for Oracle][Oracle]ORA-01722: invalid number (#1722)".
When I look at the Oracle documentation I got this:
ORA-01722 invalid number
Cause: The attempted conversion of a character string to a number failed
because the character string was not a valid numeric literal. Only numeric fields or character fields containing numeric data may be used in arithmetic functions or expressions. Only numeric fields may be added to or subtracted from dates.
Action: Check the character strings in the function or expression. Check that
they contain only numbers, a sign, a decimal point, and the character "E" or "e" and retry the operation.
I checked the INSERT statement: "INSERT INTO AFM_HV_PROP_VALUE (HV_INST_ID, HV_PROPERTY_ID, TABLE_NAME, HV_PROPERTY_VALUE) VALUES (4, 'V_TESTJE', 'hv_inst', '123465')" and everything seems to be allright. The value that's causing the error is the "4" that gets in the "HV_INST_ID"-field.
Using TOAD to execute the SQL Statement, there is no problem at all.
When I look at the table design in MS Access I see that the Autonumber field is of the type "Double". That doesn't seem right to me...
Anyone some suggestions? I'm running out of courage :s
Greetings,
Niels R.
We have a user that wants to pull data from multiple oracle tables into one access table. She will probably want to run this process daily. The tables will join easy enough, but I wasn't sure what the best way to go about doing this was.
I haven't used access very much. Again, this is a member of the user community and she is wanting to do this thru access.
Ideally, if it could be automated some way, or set up in some way where the user would not have to do much more than start the process (and not have to redo any "select" statements each time). I would assume some kind of combination of links and import (maybe using a macro?), but again I know very little about access.
Any guidance will be appreciated!
I am splitting a database and have created the Back end already. When I create the front end and link to the tables on the back end... The front end does not link to all the tables in the back end. The list that comes up when creating the linkings does not show all the tables in the back end. What would cause this?
View 1 Replies View RelatedI have split database (B/E is in the SharePoint library, F/E has users on a local PCs). Sometimes, when I update/add data (does not matter if it is via form or directly in the table) it looks OK, but when I re-open the database, the data are gone.
Problem is that I cannot catch the moment when data were not saved (sometimes data are saved, sometimes not). I can point out this: if I re-enter the missing data, primary key continues subsequently, it looks like the data have never been entered. I tried to use script
Code:
If Me.Dirty Then Me.Dirty = False
on "On Close" form event, does not work.
B/E is linked by VBA code and it looks OK (no error, Link Manager shows correct path). I suspect interrupted connetion to the SharePoint but I don't know how to check it. I implemented VBA script co keep open connection to the SP but the issue persists.
Hi,
Can anybody help me ?
I've a case where ms access displays oracle's numeric field as text where msaccess is linked to oracle.The possible reason could be when we don't specify precision in declaring the filed in oracle table, default precision is 38 which ms access cannot hold. So, it(driver) converts this to text field.But this is with MSORCL32.dll(microsoft driver for oracle).Is there any other possible reason that will result this behavior?
The following are the configuration details:
1.Oracle 9i on Unix server.
2.MSAccess on Windows XP.
MSAccess holds linked data of Oracle server.
Thanks Inadvance.
