My problem is that I am getting a mysql database with lots of tables. And the need to output the same document as the file I attach, Is there any tool that supports this?
Thanks so much.
The information you want is in the INFORMATION_SCHEMA.COLUMNS table, or the output of SHOW COLUMNS.
there is a tool to select the column from each table you want to extract on excel.
check Microsoft tutorial
you should obtain this menu :
enter image description here
and you just drop the column you want

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 to get the SHOW CREATE TABLE tblName output of all the tables and write it to files (one file for each table).
Anyone can help me how I can begin to this? I suppose stored procedures? I am pretty sure that there is a tutorial I can follow because MySQL has a big community..
Thanks in advance
Some pictures of the output I need of each table:
Since your screenshot shows that you're using Windows; you can use HeidiSQL for your task.
There's an option in tools, titled Export database as SQL.
I am looking for a way to select a full MySQL database in talend and use it as source to generate an XML.
Currently I'm trying with the tMysqlInput component but I can only select individual table. I've 10+ table and I want to rebuilt my data with several tMap. So I'm looking for a component or way to get the full database in one shot.
Thanks in advance for your help!
I would say that you need one tMysqlInput per table. That's the Talend logic.
What I suggest you to do :
Retrieve all table schemas using Talend
Drag & Drop the created schema to the Talend Designer and select tMysqlInput
Your newly tMysqlInput should already be set to use the corresponding schema (repository mode)
If you press "Guess query" in the tMysqlInput settings, it will list all columns
Depending on what you are trying to achieve, take a look at the tMysqlTableList https://help.talend.com/display/TalendOpenStudioComponentsReferenceGuide521EN/7.65+tMysqlTableList
EDIT
Talend can make JOINs directly in the tMap component. A good example can be found here : http://techblog.appirio.com/2009/12/performing-lookups-and-transformations.html
I have downloaded a mysql table in text format from one our collaborator's. I have dumped the table into a table on mysql database on my machine successfully. The table was created using their sql file. SO they have some of the fields with blob data-type, and I am unable to view them in mysql. when I opened the same downloaded text file with csv I could see the fields with blob data-type with letters like BC,ABD,BDS. I do not understand why I am unable to view the fields in mysql. Anyone have ideas?
This is sure you can not see the blob data directly when you view the table data from mysql. But i think when you click the edit link of particular row you might see the data but i'm not sure about this. If you are using any server script then you definitely gonna see data without any hassle using simple select query. Like
SELECT COLUMN_NAME FROM TABLE_NAME
// REGARDLESS OF COLUMN_NAME DATA TYPE
i have to build an application to manage an existing MySQL database. This database was created with MySQLworkbench and some useful comments were added to its tables and columns.
I think it would be great to somehow, query that comments and show them to the user to explain "what that field is". The problem is i don't know if its possible to retrieve that comments (they are only visible from the workbench).
EDIT:
in the MySQL existing database i have to work with there is no INFORMATION_SCHEMA table. I think is something usual to find it but in my model there is no :S
Try with:
SELECT column_comment FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME='table_name';
You can parse the output of
show create table `YOURTABLE`;
