You're going to need 3 major components:

1.tFileInputDelimited

2.tMap

3.a Database output component

• Use the tFileInputDelimited component to insert your CSV file.
• Connect the tFileInputDelimited to the tMap component and map the columns you want to insert into your database.
• Connect the tMap component to the Database output component using the output you created in tMap and ensuring all the database information is correct within the Database output component. 

Should look something like this when done.

Hello, I am kinda new to Talend I understood CSV to DataBase.

But I have one scenario that I could not find any where.

I have to do csv to DataBase but I don't have column id in csv but I have it in my table which is primary key and not auto increment.

And I have to dump CSV data in table in such a way that for every record in CSV I have to put id in table as max(id+1)

please help....... I am trying this since last 2 weeks.

Hi Roshan,

      Could you please try below method.

Step 1:- Take the maximum value of the DB and store it in a context variable

Step 2:- Use a numeric sequence and instead of starting from 1, use the context variable+1 as the starting value.

Then the number will increment from that specific value. Please refer the screen shot for details.

Numeric.sequence("s1",(context.max_number+1),1) 

Warm Regards,

Usually Tschemacomplance check is better to use from CSV to database, because while testing goes, Testers will always put more than the maximum value and test, than entire job fails, Please look at below example for this. It is better to design in this way
