Q:

What are the difference between in-stream procedure and inline procedure in JCL ?

Answer

An in-stream PROC is defined right in the jcl stream and doesn't reside in the proclib. This is an older technique associated with punched cards but it is still in use with setup and installation programs from vendors.


for the in-line perform instead of:


perform add-paragraph until switch = 'y'


you can code


perform until switch = 'y'


body of code


end-perform


body of code is the code from add-paragraph appearing in-line (ie right in the perform) instead of in a separate paragraph (out of line code)

Q:

What is the difference between JOIN and UNION?

Answer

SQL JOIN allows access to records of other table based on the given conditions between two tables.


Ex: If we are provided with the department ID of each employee, then we can use the department ID of the employee table to merge with the department ID of the department table to access department names.


UNION operation allows addition of 2 similar data sets to create a resulting set that contains all the data from the source data sets.


Ex: If we are provided with 2 employee tables of the same structure, we can UNION them to create a singular result that will contain all employee from both the table.
