Lets discuss diff cases:
1. If the two tables having same key column,
then based on that key column we can able join the two
tables. It's horizantal joining.
Ex: Table1 has 10 columns +1Key col
Table2 has 5 columns +1Key col
in target SeqFile we get 10+5+1 columns

2. If the two tables having same metadata,
Then using funnel stage we can perform vertical joining.
whether it may continuous or sequence funnel.
In this case we can add extra columns 'INDICATOR'(1 for
Table1 and 2 for Table2 records in the select query) to
identify records

3. If the two tables not having same metadata & Key column,
We can generate 1 common Key column from Column Generator
Stage- 'DUMMY'(values: 1,2,3,4,...) for 2 tables
Then, we can join based on DUMMY column to get all the
columns from the both tables and load those columns to
SeqFile.

create a job that splits the data in the Jobs.txt file into four output files. You will direct the data to the different output files using constraints. • Job name: JobLevels • Source file: Jobs.txt • Target file 1: LowLevelJobs.txt − min_lvl between 0 and 25 inclusive. − Same column types and headings as Jobs.txt. − Include column names in the first line of the output file. − Job description column should be preceded by the string “Job Title:” and embedded within square brackets. For example, if the job description is “Designer”, the derived value is: “Job Title: [Designer]”. • Target file 2: MidLevelJobs.txt − min_lvl between 26 and 100 inclusive. − Same format and derivations as Target file 1. • Target file 3: HighLevelJobs.txt − min_lvl between 101 and 500 inclusive. − Same format and derivations as Target file 1. • Rejects file: JobRejects.txt − min_lvl is out of range, i.e., below 0 or above 500. − This file has only two columns: job_id and reject_desc. − reject_desc is a variable-length text field, maximum length 100. It should contain a string of the form: “Level out of range: ”, where is the value in the min_lvl field. My Question is how do you write the stage variable for reject rows.
