DECODE( ) function in SQL Server

Question

SELECT PC_COMP_CODE,
       \'R\',
       PC_RESUB_REF,
       DECODE(PC_SL_LDGR_CODE, \'02\', \'DR\', \'CR\'),
       PC_DEPT_NO DEPT,
       \'\', --PC_DEPT_NO,
           


        

Answer 1

Just for completeness (because nobody else posted the most obvious answer):

Oracle:

DECODE(PC_SL_LDGR_CODE, '02', 'DR', 'CR')

MSSQL (2012+):

IIF(PC_SL_LDGR_CODE='02', 'DR', 'CR')

The bad news:

DECODE with more than 4 arguments would result in an ugly IIF cascade
