列の値は、mysqlのテーブルに

Question

SELECT logic_id 
FROM business_logic_details 
WHERE if(form_completion != 0.00,form_completion,0) = '90' 
    AND if(query_type IS NOT NULL 
     OR query_type !='',query_type,0) LIKE '%domestic%' 
    AND if(client_type IS NOT NULL 
     OR client_type !='',client_type,0) LIKE '%existing%' 
    AND if(tour_package IS NOT NULL 
     OR tour_package !='',tour_package,0) LIKE '%S%' 
    AND if(tour_type IS NOT NULL 
     OR tour_type !='',tour_type,0) LIKE '%2%' 
    AND if(currency IS NOT NULL 
     OR currency !='',currency,0) = 'INR' 
    AND if(country IS NOT NULL 
     OR country !='',country,0) = '105' 
    AND if(adults IS NOT NULL 
     OR adults !='',adults,0) = '1' 
    AND if(duration_of_stay IS NOT NULL 
     OR duration_of_stay !='',duration_of_stay,0) = '5' 
ORDER BY logic_id ASC

そのため使用COALESCE関数検索するためのnullまたは空の場合は、列を無視します：

SELECT logic_id 
FROM business_logic_details 
WHERE COALESCE(form_completion, 90) = 90 
    AND COALESCE(query_type, 'domestic') LIKE '%domestic%' 
     ... 

を私も強く整数としてではなく、文字列として整数を比較することをお勧め：

グッド：0 = 90
悪い：0 = '90'
