Question

I have the following query that needs to be converted from Oracel PL/SQL to T-SQL to accomodate a data source change.

How can the Oracle join (+) convert to T-SQL?

SELECT INA01 , SMYDESC , CASE WHEN INACONF = 'Y' THEN '0' ELSE '1' END  , INB15 , AZF03  , INAORIU  , ZX02  , INADATE  , INA04  , GEM02  , INA02  , INA11  , INA07  , INB03  , INB04  , IMA02 , INB09 , INB08 , INBUD02
       FROM INA_FILE , SMY_FILE , GEM_FILE , INB_FILE , IMA_FILE , AZF_FILE , ZX_FILE
       WHERE INA00 = '1'                                 
         AND INACONF <> 'X'
         AND INA01 = INB01
         AND INB04 = IMA01(+)
         AND SUBSTRING(INA01,1,5) = SMYSLIP(+)
         AND SUBSTRING(INA01,1,5) NOT IN ('0IN99','1IN03','0IN92','1IN04','0IN98')
         AND INA04             = GEM01(+)
         AND INB15             = AZF01(+)
         AND INAORIU           = ZX01(+)
         AND INACONF           = 'Y'                     
         AND inadate = to_date('2012/05/23', 'yyyy/mm/dd')

You probably need to add table names in front of the column names in the JOIN clauses:

SELECT INA01, SMYDESC, 
       CASE WHEN INACONF = 'Y' THEN '0' ELSE '1' END, 
       INB15, AZF03 , INAORIU , ZX02, INADATE, INA04, GEM02, INA02, 
       INA11, INA07, INB03, INB04, IMA02, INB09, INB08, INBUD02
FROM INA_FILE 
INNER JOIN INB_FILE ON INA01 = INB01
LEFT OUTER JOIN IMA_FILE ON INB04 = IMA01
LEFT OUTER JOIN GEM_FILE ON INA04 = GEM01
LEFT OUTER JOIN AZF_FILE ON INB15 = AZF01
LEFT OUTER JOIN SMY_FILE ON SUBSTRING(INA01,1,5) = SMYSLIP
LEFT OUTER JOIN ZX_FILE ON INAORIU = ZX01
WHERE INA00 = '1'                                 
AND INACONF <> 'X'
AND SUBSTRING(INA01,1,5) NOT IN ('0IN99','1IN03','0IN92','1IN04','0IN98')
AND INACONF = 'Y'                     
AND inadate = CONVERT(DATETIME, '05/23/2012', 101)
