pymysql.err.InternalError: (1054, Unknown column '27D24A3B' in 'where clause')之错误解决
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
原代碼：
query_image_path1='SELECT imageTempFilename_0,imageTempFilename_1 FROM %s'% tablename query_image_path2=' where IDprojectTemp=%s and IDproject=%s and cameraID=%s and imageflag=%s'%(IDprojectTemp,IDproject,cameraID,imageflag) query_image_path_sql=query_image_path1+query_image_path2 print(query_image_path_sql) cursor.execute(query_image_path_sql) value_list = cursor.fetchall()###################################### #query_image_path_sql:SELECT imageTempFilename_0,imageTempFilename_1 FROM engineeringdata20190124 where IDprojectTemp=27D24A3B-ECF3-40ff-BC79-9A0B8417A0CD and IDproject=C3A9B395-12A5-4821-AD00-B8C02E5C3904 and cameraID=1 and imageflag=0運行出現錯誤：pymysql.err.InternalError: (1054, "Unknown column '27D24A3B' in 'where clause'")
將query_image_path2中的單引號改為雙引號。%s上加雙引號，則不報錯。改正后如下：
query_image_path1='SELECT imageTempFilename_0,imageTempFilename_1 FROM %s'% tablename query_image_path2=" where IDprojectTemp='%s' and IDproject='%s' and cameraID='%s' and imageflag='%s'"%(IDprojectTemp,IDproject,cameraID,imageflag) query_image_path_sql=query_image_path1+query_image_path2 print(query_image_path_sql) cursor.execute(query_image_path_sql) value_list = cursor.fetchall() print('value_list:', value_list)?
總結
