Question

Мой SP выглядит следующим образом:

ALTER PROC ME_SP_GETORDERASSIGNMENT_DETAILS       
@COMPANY_CODE VARCHAR(5),                 
@TRANSID VARCHAR(10),

Этот SP выдает ошибку «Неправильный синтаксис около„>“.»

Мне нужно сделать, если @FROM_DATE и @TO_DATE оба пустые, а затем после оператора AND I.ACTIVE = 1 никакое условие не должно добавляться. Если @FROM_DATE не является пустым, а @TO_DATE пуст, тогда одно условие должно быть добавлено как это для всех сценариев. Как решить эту проблему?

Answer 1

Предикат с участием CASE не был должным образом сформирован:

AND CASE 
     WHEN ... THEN ... 
     WHEN ... THEN ... 
    END -- missing a condition here 

Чтобы это исправить, переделать свой CASE заявление так:

AND 
CASE   
    WHEN (isnull(@FROM_DATE,'')<>'' and ISNULL(@TO_DATE,'')='') and Convert(date,A.order_date) >=CONVERT(datetime,@FROM_DATE,105) THEN 1 
    WHEN isnull(@FROM_DATE,'')='' and ISNULL(@TO_DATE,'')<>'' and Convert(date,A.order_date)<=CONVERT(datetime,@TO_DATE,105) THEN 1 
    WHEN isnull(@FROM_DATE,'')<>'' and ISNULL(@TO_DATE,'')<>'' and Convert(date,A.order_date)<=CONVERT(datetime,@TO_DATE,105) and CONVERT(Date,A.ORDER_DATE)>=CONVERT(datetime,@FROM_DATE ,105)) THEN 1 
    ELSE 0 
END = 1
