警告1292當我在mysql中使用像Python一樣使用

Question

我必須檢查我的數據庫中是否有空， 和我需要檢查11列（由or）和加上和像年（如2017%）。

def test(): 
    sql= "select date from a000760 where (total_assets is null or total_liabilities is null or sales_figures is null or sales_cost is null or business_profits is null or gross_margin is null or current_income is null or depreciation_expense_of_tangible_assets is null or liquid_asset is null or noncurrent_asset is null or liquid_liability is null) and (date like '2010%')" 
    curs.execute(sql) 
    #year="2010" 
    #curs.execute("select date from a000760 where (total_assets is null or total_liabilities is null or sales_figures is null or sales_cost is null or business_profits is null or gross_margin is null or current_income is null or depreciation_expense_of_tangible_assets is null or liquid_asset is null or noncurrent_asset is null or liquid_liability is null) and (date like %s)",year) 
    result = curs.fetchall() 
    if len(result)>0: // print shows() even if it's none. so, I use this 
     print "a000760" 
     print "2010 null exists" 

這是一張表的測試版本。 我必須檢查超過2000個表格。 它適用於此def並顯示錯誤（僅適用於一個表格）。 但它不適用於總表。 我得到這個錯誤：

Warning: (1292, "Incorrect date value: '2010%' for column 'date' at row 1") 

我不知道該怎麼... 我搜索了整個語法， 但是當我鍵入%2017%這是行不通的。

Answer 1

請勿在日期中使用like！日期不是字符串。

你可以這樣做：

year(date) = 2010 

或者：

date >= '2010-01-01' and date < '2011-01-01'
