Answer / madhusudhanreddy t

Some of the answers posted are good, but the real things to
do in order to improve the performance of the crystal
reports are:

- Server Side processing should be done.This can be achieved
by using the option PERFORM GROUPING ON SERVER.

-Using Indexes for faster data retrieval also improves the
performance of the reports.This can be achieved by using the
option USE INDEXES FOR SPEED.

- Instead of using the Formula Fields the other option
provided is SQL Expression Fields to improve the
performance. Using Stored Procedures is also very good
option since they are pre-compiled sql statements which are
permanently stored in the database where syntax checking
will not be done for each individual query.

-If you are using Sub Reports, then you can use the ON
DEMAND SUB REPORTS instead of normal sub reports. Since
using the normal sub reports will be a cost factor to
retrieve the data from the data source.

-Using Linked Tables with Indexes is the better option
instead of sub reports. Again it depends upon your requirement.

-Instead of retrieving all the records, its always
recommended to fetch only the necessary records using the
where condition.

They are still many points to be noted....as far as for
interview point.....providing these answers will surely
place you in a right position.

One more interview question If I have the data where some columns have multiple values in a given row of data returned from the database. The stored procedure returns data as it is that is blanks values and non blank values. However, I need to suppress the blank values not by showing 0 values but by shifting the cells up. Is there a way using a formula to shift the blank cell one row up based on a selection critieria? In the example below, I want to get rid of the blank values under Exposure column without replacing with 0. example: Company Margin Exposure AB 500 3 10 7 8 ABC 200 4 2 5 10 Thanks Anita
