How to get multiresult with multicondition in Sql Server - sql

Question

I need help to solve this.
Hopefully someone can giving me advices.
For a sample, I've got data like :
PROCLIB.MARCH 1
First 10 Rows Only
Flight Date Depart Orig Dest Miles Boarded Capacity
-----------------------------------------------------------------
114 01MAR94 7:10 LGA LAX 2475 172 210
202 01MAR94 10:43 LGA ORD 740 151 210
219 01MAR94 9:31 LGA LON 3442 198 250
622 01MAR94 12:19 LGA FRA 3857 207 250
132 01MAR94 15:35 LGA YYZ 366 115 178
271 01MAR94 13:17 LGA PAR 3635 138 250
302 01MAR94 20:22 LGA WAS 229 105 180
114 02MAR94 7:10 LGA LAX 2475 119 210
202 02MAR94 10:43 LGA ORD 740 120 210
219 02MAR94 9:31 LGA LON 3442 147 250
and i have condition for ('LAX,ORD'), 'LAX','LON','YYZ',('PAR,LON,FRA'),'FRA' ...AND ELSE
What should i do with that data to show report as that condition in SQL?
Parameter that I made is
Dest like #dest -> (from table condition(('LAX, ORD'), 'LAX','LON',('PAR,LON,FRA'),'FRA',..etc)) +'%'
And Date like #date + '%'
And Depart like #depart + '%'
If I choose 'LAX' as #dest, then only 'LAX' will show
If I choose 'LAX,ORD' as #dest, then only 'LAX' and 'ORD' will show
Please I need help, advice and suggestion for this.
Thanks

Answer 1

If your #dest value is 'LAX,ORD', one query that will solve your solution is
select *
from PROCLIB.MARCH
where dest in ('LAX','ORD')
To parameterise that, you need it to become a table.
Dest
====
LAX
ORD
and the query becomes
select *
from PROCLIB.MARCH
where dest in (select Dest from #DestTable)
If you want to pass #dest as a string parameter, then you need to split it somehow into a table. A search for SQL split function will give a number of options.
If your query is encapsulated in a stored procedure, a better method is to pass the values as a table valued parameter. See http://blog.sqlauthority.com/2008/08/31/sql-server-table-valued-parameters-in-sql-server-2008/
