I have two Database for example "Database1" another is "Database2" whose location at 'Libraries\Documents' at my pc. Now I want to select one column named it "Column3" where another column "ID" of Database1 equal to Database2. So how can I write this query? And also how can I get those data from different database and same or different location of database? please explain with query example. I found it only for SQL but not for Access database 2013.
Thanks in advance.
Did you try link tables from 2nd file into 1st file?
From one Access DB file you can link tables from various data sources, including all kinds of other databases or excel, csv, xml files, and then you can treat them as "linked table",
for all the local tables and linked tables you can easily join them and build up queries.
It is one of the many handy features that i like to use MS Access for quick and easy tasks.
Hope this helps.

I have a database wordpress consisting a lot of tables. I am looking for a certain entry 20.22.31.44. What is the best way to return the table and column if this entry exists?
You can dump your database data (SQLDump) into a file and search through it's content.
You may also use a Database Management system (i.e. Workbench, PHPMyAdmin) to perform that global search for you. See related.
I'm implementing my first Access Database. I've read numerous guides/manuals, and I believe I'm nearly at the finish line. The Access Database will be used by 3-4 users.
I have three tables, all of which are "live" connections to three different Excel file. These Excel files are on a shared drive, which are to be updated periodically by the different users.
I have a single query that uses each of the different tables (3).
The goal is to give the users the ability to view the output of the query. From my understanding, the best way to structure Access is to split the database. I'd like the three tables to be stored in the "Back-End" database, and the Query to be on the "Front-End" database.
The issue that I'm running into is that, when using the "Database Splitter", I'm given the error "There are no tables in this database. The back-end database will be empty". I've searched for the past couple hours, but I can't seem to find a reason for this error. I believe it is quite clear that I do indeed have tables. What am I missing? Any input/suggestions are greatly appreciated!
The "Database Splitter" can be used when you have tables and front-end things in your database. The "Splitter" would then create an additional Access database, "move" the tables to the new database and create linked tables in the old database that map the the tables in the new database. You already have linked tables, so there's nothing to split (your linked tables are not even Access tables).
I'm using Pentaho Data Integration for my ETL process...
I have multiple excel files that I need to merge and upload in one database. However, I cannot Distribute the fields into its corresponding tables in the database. I can only send it to one table at a time. Is there any other way to do this? How can I have multiple target table?
P.S. I'm using MySQL Workbench for the database.
Thank you for your help!
You can connect multiple Table output steps to your last processing step and set it to copy all rows to both or all target steps. Connect Table outputs (or Insert/update, etc) like in the image, then right-click the step where the stream splits and select Copy Data to Next Steps. In the Table outputs you obviously only specify the columns that apply to that table.
I have inserted new columns in one database, and I now want to add the same type of columns to a second database. I need to know which columns are in the first database that are not in the second. I have many tables in each database that needs column difference comparing. I searched the web and I can only find ways to see the difference of the contents of columns in two tables. I don't need to compare the contents, just different columns in all the tables in each database. Each database has the same tables.
Thanks!
I found that you can do a database dump that just has the structure from phpmyadmin.
Are you doing this manually? You could just use SHOW CREATE to see the structure of the tables, and then something like the diff command in Linux to compare them.
For a commercial product answer: I use Red Gate's SQL Compare which works great. It can compare the entire schema of two databases. It can also update your target database to match your source database.
Use redgate SQL compare to comapre schema of two tables.
sql-dbdiff works well too. Its an open source.
I am new to access and have mostly worked with SQL Server. I am trying to accomplish a task for our users and am not sure how to approach it.
We have a situation where the users need to manipulate some data in various access tables, then put the final results into one of several 'linked tables' that are defined in SQL Server and linked to access. The sql server tables will defined very generically with column names like 'col1', 'col2' etc to allow for different types of data to be uploaded.
What I would like to do is have some kind of macro or module that does this:
1) Lets the user select the source (access table)
2) Lets the user select destination (linked sql server) table
3) Lets the user map the columns he would like to copy from the source to the destination table. (If this is too difficult then just something that would copy the first x number of columns would work).
4) Deletes all pre-existing data from the target table
5) Copies all data from the source table to the target table.
Could someone give me an idea as to what would be the best approach or maybe even an example of some code that does something similar? Thanks in advance. We are using Microsoft Access 2010.
