將Oracle加入（+）從Oracle PL/SQL轉換爲Microsoft T-SQL

Question

我有以下查詢需要從Oracel PL/SQL轉換爲T-SQL以適應數據源更改。

Oracle如何加入（+）轉換爲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') 

Answer 1

你可能需要在列名前加上表名在JOIN子句：

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) 

Answer 2

這是一個適用於outer join運算符的原生Oracle語法。

UPD：爲了幫助你真正重寫此查詢我需要知道的表結構，不要將您的where子句中使用任何表引用 - 僅列，這似乎是獨特的桌面。

我作出了關於您的架構的一些假設......但這樣的事情

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 join inb_file on ina01 = inb01 
      left join SMY_FILE on SUBSTRING(INA01,1,5) = SMYSLIP 
      left join GEM_FILE on INA04 = GEM01 
      join INB_FILE on INA01 = INB01 
      left join IMA_FILE on INB04 = IMA01 
      left join AZF_FILE on INB15 = AZF01 
    WHERE INA00 = '1'         
      AND INACONF <> 'X' 
      AND SUBSTRING(INA01,1,5) NOT IN ('0IN99','1IN03','0IN92','1IN04','0IN98') 
      AND INACONF = 'Y'      
      AND inadate = '2012-05-23'
