我想在以後的查詢中使用sqlite查詢的結果。在下面的代碼中,請注意exam [1]是一個字符串,'endtime'打印正確。但是,我似乎無法將它傳遞給db.execute語句。更麻煩的是,如果我從python命令行執行相同的操作(將endtime設置爲字符串並調用db.execute語句),它將按預期工作。任何關於我失蹤的想法。如何將datetime傳遞到sqlite
exam_list由兩個日期時間字符串和一個uuid組成。我也嘗試將相同的結果作爲(kiosk,exam [1],exam [1])傳遞。
for exam in exam_list:
print "%s\t%s\n%s\t%s\n%s\t%s\n" % (exam[0],type(exam[0]),exam[1],type(exam[1]),exam[2],type(exam[2]),)
endtime = exam[1]
print "Endtime is %s" % (endtime)
db.execute("""select sessionid, examtype, email from schedule where stationid = ? and iestart < ? and ieend > ? and status = 'Pending' """, (kiosk, endtime, endtime,))
