Converting Data Types With Linked Tables

Aug 3, 2007

Hi,

I have 2 linked tables, I would like to join these tables in access, however the first table's field is a memo and the second table is a number. I have tried to cint() the field in a query but I get an error message "Explicit conversion from datatype text to smallint is not allowed"

Any ideas how to get around this problem?

Thanks

Michael

Tables :: Data In Linked Back End Tables Not Saved From Front End

Jun 19, 2015

I 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.

Importing Data Into Linked Tables?

Aug 11, 2005

I'm trying to perform a massive data dump. I have about 1,000 records that need to be added into my database. This is coming off an Excel spreadsheet.

I don't know if this is possible:
I have a table, tblTorders, which is linked to the table, tblItems.
When I open the tblTorders, I can click on the plus sign to expand and see the related data in tblItems.

How can I import data to populate the fields in both of these tables? I can't use the import function because you can only select to import it into one table.

Do I do it through a query.... I'm not sure where to go on this one.

Thanks so much

Tables :: Appending Data To A Linked Table?

Feb 6, 2014

I have a table in MS Access 2010 that is a link to an external data file in .csv format. I assumed that it was not possible to append data to a linked table until recently. I appended 3 records to the linked table and discovered that the 3 records were appended to the table and the external data file it was linked to.

What am I missing ?

ID Fields: Data Type Differs In Linked Tables

Apr 6, 2006

I have a database consisting of three linked tables, with ID as unique identifier (primary key).

I would have expected the data type for my unique identifier, especially in the main table, to be Autonumber. However, I discovered with some surprise that the primary key (ID) in

Table 1 (Main table) is data type: number, field size: double

whereas in table 2 and table 3 the ID is data type: autonumber (field size: long integer)

It must have happend "SOMEHOW" when I divided the original single table.

Is this as it should be? Or could it lead to trouble later on?

If not as should be, is there anything I can do right now to rectify the situation with risking upsetting the relationships and all?

What precautions should I take, apart from taking a backup?

Thanks for your help.

Importing Of Data From Excel/Access To Two Tables Linked By A Querry

Jun 28, 2006

Dear Sir/Madam,

I am having the problem of importing a database from Excel/Msaccess 2000 to a Msaccess 2000 database from which the data was originally exported. The Database consists of two tables connected in a querry and the two tables has a unique primary key thru which the two tables are linked using a querry. While importing only two tables are listed in the importing wizard and not the querry.

So how to import the data to the two tables connected by a querry using a primary unique key.

Linked Tables Not Pulling Back Field Data Correctly

Jun 13, 2012

I'm a bit new to Access but have managed to build a very simple database.

I have a main table which I need to add 4 columns onto the end of, the data for which comes from 4 tables linked to it. Below is how they are linked.

Main table------> Table 1
Main table------> Table 2
Main table------> Table 3
Main table------> Table 4

All 4 relationships have a join type of 2 (Include ALL records from 'Main table' and only those records from 'Table1/2/3/4' where the joined fields are equal)

However, 3 of them pull back the correct data when I refresh the Main table, but the 4th one doesn't - which appears to be to be set up in the exact same way. It does bring back data, but it's the wrong data or in the wrong order.

For example, if the related field in the Main table is "Sarah" - It needs to bring back "Programme", but some Sarah's pull through Programme, some are blank and some are another option altogether. Table 4 has no duplicates or typos etc and I've tried deleting it, loading it in again and creating a new relationship but nothing seems to work.

How To Create A Form That Can Update Data Linked To Multiple Tables

Jul 30, 2012

I'm using Access and Excel 2007.... I know how to import an Excel spreadsheet as a table.

I have several supplier price lists in Excel. I want to keep my vendor price lists up to date.

When one of my vendors tell me that a price has changed on a particular item, I figure that I could have a form that I could use to enter the changes.

I believe the form would look like:

Field: "Vendor" (drop down list to choose from. Name of the Supplier price lists) Required.
Field: "OEM" (Key Field found in each table) Required.
Field: "Brand" (Field found in each table) Not required.
Field: "Price" (Field found in each table) Required.

OEM would be the unique key field.

If I enter the Vendor name and then the OEM number it would show if there is already that number in the Vendor price list and I could make changes. Or I could enter new data in that vendor price list.

Data Types

Sep 5, 2005

I have an Excel file (sourced externally) linked as a table. All fields are defined as text fields. In some of the Excel cells, data has somehow been entered as numeric (eg phone number). When I query the Excel file thru Access, these fields show up as errors (#num!).

I need to find a way of interogating the field, and if in error (like these ones), then ignore it, or replace with zeros etc.

I cant find a way of doing this. Help :)

Replace And Data Types

Jan 26, 2006

Hi all!
I'm experiencing an apparently simple problem, but it's taking me too long to solve :confused:
Two tables with a "text" (100) column on each. I want to select those who are identical. ¡So easy! thats the where clause:

AND a.sDesEntidad = b.sNombreLargo

That works fine. But... i want to "relax" the clause, by not considering dots ( . ) when comparing, and i do like this:

AND (Replace([a]![sDesEntidad],'.','') = Replace([b]![sNombreLargo],'.',''));

and i get a run-time Error 3464, Data type mismatch in criteria expression. Oooops!
My access version is 2003, spanish. I would really appreciate ur help, since this matter shouldn't be keeping me busy for so long :(
Regards and thx in advance!

Wondering if anyone has a solution for my problem.

I have 2 data sources, one which is an ODBC and one which is an import table. I have a 2 queries each querying the 2 data sources seperatly.

My problem is... One of the fields which I need to do a join to a reference table has a different data type in each of the data sources. I have tried changing this in the imported table NO JOY!! You cant change the data type in the ODBC link.

Is the anyway round this?

Any help appreciated...

Access Data Types

Feb 9, 2006

I am trying to do a comparison between two values and am getting the following error:

Microsoft JET Database Engine error '80040e07'
Data type mismatch in criteria expression.

The code that is creating the error is as follows:

sb = Request.Form("storyboardscreen")

if Not Lcase(Request.Form("AllStoryBoard")) = "all" then
whereClause = whereClause + "theStoryboard = " + sb
end if

I am using the statement to build the where clause of my query. The sb value is retrieved from a pull down menu and "theStoryboard" column is the db is of data type "text". The values stored in the field are 12 digit numbers. I have tried doing a cstr to sb but that doesnt work, any tips on what I am doing wrong? I am using asp with an access db....

Thanks

Union Query Data Types

Dec 11, 2007

Hi All,

I have a Union query that brings together several tables into one. This works perfectly well however there is an occassion when a field in one table has its data type changed to text from date. This is to allow N/A to be entered rather than a date. When this occurs the union query changes all the dates from the other tables to text also and therefore other queries I am running based on the Union query now fail.

Is there any way to have the Union Query ignore the data from the table where and when this this occurs as it is not necessary to show in the query and can happen with any of the tables at a users discretion

Thanks Again
IC

Relinking Multiple Linked Tables That Are Linked To Different Databases

Feb 2, 2012

I have a database with a number of linked tables that are linked to tables in different databases (not a back-end).for example, I have table1 that is linked to table1 in K:databasedb1.mdb.table2 linked to table2 in S:datadata.mdb.and so on...

However, recently we have moved all our databases to a new location.

K:databasedb1.mdb is now residing in O:masterdatabase
and S:datadata.mdb is now residing in O:masterdata
and so on...

I'm now in charge of relinking all those tables to point to the new location.I would do this in linked table manager one by one but we have 100s of tables linked to multiple different databases in different location.is there a way to create a VBA code that will automatically do this re-linking process?

so,
1. find unlinkable tables
2. search its new location under O:master
3. re-link it to the new location

Database names and tables names have not been changed. Just the location of databases.

Converting ODBC Tables To Access Tables

Oct 5, 2007

Hello, this is my first post (anywhere ever)!:eek:

While I have lots of Access programming experience over the years I have broken new ground this week and am in unchartered territory and need help please!

In the organization I am working for (as Procurement Manger), we use AMMS (by Microwest) for work order generation and inventory management, etc. I have been able to import into Access the tables of interest from this SQL-based package. The problem is that I need to share the tables (via nice front end forms/queries) with about 20-30 people in the field.

I don't know much about ODBC but the administrator of AMMS was kind enough to give me access to the AMMS database tables via ODBC and I, personally have access to read the table data but none of the other people in the field can access these tables due to security rights.

So, what I have done is I created MS Access tables for each of the 4 AMMS tables of interest and I run code that runs delete and append queries on each table. I then have a separate public db that the field people access with all the queries and forms but only links to the Master db containing the 4 Access tables derived from the ODBC tables. This works ok but there are issues:

1) if any field people are on the Public db, the code to import the ODBC table data loops and does not complete the delete/append cycle on one or more of the tables. I can only refresh the table data when nobody is connected to the db - impractical.:(

2) the ODBC tables are rather large - one is over 38,000 records and it takes several minutes to run the delete/append queries.:mad:

3) When I created the Master db it was some 83MB. After running the delete/append queries it is some 179MB and appears to increase in size every time I run the delete/append code. When I run "compact db" it stops running after a short time. Does nothing but create a new file (db1.mdb) of the same huge size as the Master.:confused:

I suspect the most graceful solution would be to give each user rights to the ODBC tables from AMMS in Access. In this case, I wouldn't have to run delete/append queries and the data would always be in relative real time subject to the refresh timer. Unfortunately, due to AMMS licensing restrictions, this is not doable.

I have tried to search the internet for guidance but no luck. This forum appears to be an excellent opportunity to get expert advice on this particular issue. I thank you for your thoughts and guidance.
