在ORACLE的If語句中寫AND條件

我使用if語句和AND條件檢查oracle表單中的文本項。這是我按下按鈕時的代碼。我需要正確的語法建議。在ORACLE的If語句中寫AND條件

BEGIN  
    IF  
    :LAND_MANAGEMENT.COMPANY  AND 
    :LAND_MANAGEMENT.LAND_TYPE   AND  
    :LAND_MANAGEMENT.DEED_NO    AND 
    :LAND_MANAGEMENT.LAND_TITLE   AND 
    :LAND_MANAGEMENT.LAND_SELLER_NAME  AND 
    :LAND_MANAGEMENT.LAND_AREA   AND  
    :LAND_MANAGEMENT.DEED_VALUE   AND 
    :LAND_MANAGEMENT.ACTUAL_COAST   AND 
    :LAND_MANAGEMENT.REGISTRATION_COAST IS NOT NULL THEN 

    commit_form; 
    GO_BLOCK('RECORDVIEW'); 
    EXECUTE_QUERY();   
    GO_BLOCK('LAND_MANAGEMENT'); 
    create_record; 
    Clear_block(no_validate); 
    FIRST_RECORD; 
    GO_ITEM('LAND_MANAGEMENT.COMPANY'); 
    END IF; 
    END;

好吧，首先，的X，Y空校驗和z不寫'X和Y z不是NULL'，它的'x不是NULL，y不是NULL且z不是NULL'。 –

感謝您的幫助 –

and運算符應用於條件之間，而不是列之間。你需要檢查每列null依賴性，然後這些檢查之間適用and S：

IF  
    :LAND_MANAGEMENT.COMPANY    IS NOT NULL AND 
    :LAND_MANAGEMENT.LAND_TYPE   IS NOT NULL AND  
    :LAND_MANAGEMENT.DEED_NO    IS NOT NULL AND 
    :LAND_MANAGEMENT.LAND_TITLE   IS NOT NULL AND 
    :LAND_MANAGEMENT.LAND_SELLER_NAME  IS NOT NULL AND 
    :LAND_MANAGEMENT.LAND_AREA   IS NOT NULL AND  
    :LAND_MANAGEMENT.DEED_VALUE   IS NOT NULL AND 
    :LAND_MANAGEMENT.ACTUAL_COAST   IS NOT NULL AND 
    :LAND_MANAGEMENT.REGISTRATION_COAST IS NOT NULL THEN
