How to Write Conditional Statement in SQL Server -


i having logic issue in relation querying sql database. need exclude 3 different categories , item included in categories; however, if item under 1 of categories meets criteria category need keep said item.

this example output after querying database @ current version:

exampledb | item_num | pro_type | area     | description      1     | 45kx-76y |   flcm   | finished | coil8x     2     | 68wo-93h |   flcl   | similar  | y45kx     3     | 05rh-27n |   fldr   | finished | kh72n     4     | 84oh-95w |   flep   | final    | tar5x     5     | 81rs-67f |   flep   | final    | tar7x     6     | 48yu-40q |   flcm   | final    | bile6     7     | 19vb-89s |   fldr   | warranty | exp380     8     | 76cs-01u |   flcl   | gator    | low5     9     | 28oc-08z |   flcm   | redo     | coil34y

item_num , description in table together, , pro_type , area in 2 separate tables--a total of 3 tables pull data from.

i need construct query not pull item_num area equal to: finished, final, , redo; need pull in item_num meets type criteria: flcm , flep. in end query should this:

exampledb | item_num | pro_type | area     | description      1     | 45kx-76y |   flcm   | finished | coil8x     2     | 68wo-93h |   flcl   | similar  | y45kx     3     | 84oh-95w |   flep   | final    | tar5x     4     | 81rs-67f |   flep   | final    | tar7x     5     | 19vb-89s |   fldr   | warranty | exp380     6     | 76cs-01u |   flcl   | gator    | low5     7     | 28oc-08z |   flcm   | redo     | coil34y

try this:

select * table join... area not in('finished', 'final', 'redo') or type in('flcm', 'flep')
