Extract data from specific cell from excel and store in DB table column

[Vijay_Kumar]

Hello Experts,

I have an excel with the format as mentioned in the screenshot. I have requirement to store "Event ID" and "No.of registrants" data in MYSQL DB table. But the problem is, these value are in a specific cell in the excel (A5). I need to create a new column in my output schema and store these values against all other column values present in the excel.

I am very new to Talend, not really sure how to do it. Could you please help me to design this job in Talend.

Thank you and appreciate all your help in advance.

Hi

Use a tFileInputExcel to read the specific cell, define only one column on schema, set the Header field as 4, the limit field as 1, see

Read this specific cell value as a string, and link tFileInputExcel to a tJavaRow, extract the event ID and no. Of Registrants using Java code, store these values to context variables for used later.

In next subjob, use another tFileInputExcel to extract value from column First Name, Last Name, Company, etc, link tFileInputExcel to a tMap, add new columns, and set their values using context variables which was assigned value in previous subjob.

The job design loos like:

tFileInputExcel1--main--tJavaRow

|onsubjobok

tFileInputExcel2--main--tMap-->tMysqlOutput

Please try and let me know if you have any questions.

Hi

Here is an example Java code on tJavaRow:

context.event_id = input_row.value.substring(input_row.value.indexOf(":")+1,input_row.value.indexOf("No. of Registration"));

context.Registration = input_row.value.substring(input_row.value.lastIndexOf(":")+1);

context.event_id=context.event_id.trim();

context.Registration=context.Registration.trim();

//System.out.println(context.event_id);

//System.out.println(context.Registration);

I did't create a complete job, just guide you the way that you can follow and make some testing, I believe the process should work.
