I have around 25 tables to load to target with same structure & uses same
logic for loading. I have prepared one job which does that, but it's a
long process to design all the table. Is there any way to pass the table
name and load to target, basically a small job(in size).
I am using Talend open studio & mysqlDB.
Any help & suggestion is truly appreciated
Are you talking about 25 tables in the same database which are all of the same structure, but have different table names? Are these tables your sources? Are you loading them all into one table as your target? If so you can do this quite easily. You will need a list of your source table names in a database table or a flat file (your choice) and you will need to read that into a Talend job. Connect a tFlowToIterate to that source component. Then connect an iterate link between the tFlowToIterate component and your source db component. If your list of table names is returned to the tFlowToIterate in a column called "tablename" and the row connecting to the tFlowToIterate is called "row1", then you can reference your table name in your db component's SQL query like below.....
"SELECT Column1, Column2, Column3, Column4 FROM " + ((String)globalMap.get("row1.tablename")) + " WHERE......"
For every iteration of the tFlowToIterate, you will retrieve every row from the tablename provided to that query.
Hope that helps
Thanks for the reply, I asked for something like below.
server 1 db1 table1 >>>> server 2 db1 table1
server 1 db1 table2 >>>> server 2 db1 table2
server 1 db1 table25 >>>> server 2 db1 table25
Basically, both table in the DB for both server as same structure, just doing a tmap and sending to target.
I have just attached the image for example purpose, like this I have 25 tables.
