Question

由于源文件END_DATE列中的“ - ”数据未插入表中。

我希望这可以在以下条件下工作。

IF '-' UPDATE END_DATE = NULL
ELSE END_DATE DATE "DD-MM-YYYY"

控制文件：

infile 'Test.csv'
append into table DATA.Test
fields terminated by ','
optionally enclosed by '"'
(
  EMPLOYEE_ID
  END_DATE DATE "DD-MM-YYYY"
)

来源数据：Test.csv

EMPLOYEE_ID,END_DATE DATE
"12345","-"  
"12346","12/11/2016"

Answer 1

您可以在控制文件中使用case语句，如下所示：

infile 'Test.csv'
append into table DATA.Test
fields terminated by ','
optionally enclosed by '"'
(
EMPLOYEE_ID,
END_DATE DATE "CASE WHEN :END_DATE = '-' THEN NULL 
                    ELSE to_date(:END_DATE, 'MM/DD/YYYY') 
               END"
)

SQL加载器控制文件条件以格式化数据
