PYTHON:使用PYTHON变量更新多个列

您使用的是字符串格式,而您应该使用参数化查询。这样做:

cursor.execute("UPDATE table_name SET field1=%s, ..., field10=%s WHERE id=%s", (var1,... var10, id))

    def bscaSoporte(self, denom_sop):
        soporte = (denom_sop,) #Para que tome la variable, lista
        sql= 'SELECT * FROM SOPORTE_ID WHERE denom_sop LIKE ?'
        self.cursor1.execute(sql, soporte)
        return self.cursor1.fetchall()

    def updSoporte(self, lstNuevosVal):
        #busca soporte, SOLO HAY UNO que cumpla
        denom_sop = lstNuevosVal.pop(0)
        print(lstNuevosVal)
        encontrado = self.bscaSoporte(denom_sop)
        soporte = (denom_sop,) #Para que tome la variable, lista
        if encontrado != None:
            sqlupdate =('UPDATE SOPORTE_ID SET  dst_pln_eje = ?, geom_Z_eje = ?, \
            geom_Y_0_grd = ?, dst_hta_eje = ?,  geom_Z_0_grd = ?, \
            descrip = ? WHERE denom_sop  LIKE ?')
        #añado denom_soporte al final de la lista
        lstNuevosVal.append(denom_sop)
        self.cursor1.execute(sqlupdate, (lstNuevosVal))
        self.conexion.commit() 

lstNuevosVal 中的所有参数都要替换 sql 伊斯特努埃沃斯瓦尔

['Soporte 1', '6.35', '7.36', '8.37', '9.38', '10.39', 'Soporte 306048\nCabeza 3072589\nMáquina: Deco20\n\n']

• 您应该确保用户和密码是正确的
• 占位符的数量必须与值的数量匹配

请尝试以下代码:

db = MySQLdb.connect(host="localhost", user="user", passwd="password", db="dbname")
cursor = db.cursor()
sql_update = "UPDATE table_name SET field1=%s, field2=%s, field3=%s, field4=%s, field5=%s, field6=%s, field7=%s, field8=%s, field9=%s, field10=%s WHERE id=%s"
val =  (var1, var2, var3, var4, var5, var6, var7, var8, var9, var10, id)
cursor.execute(sql_update, val)
db.commit()
cursor.close ()
db.close()

sql_update = "UPDATE table_name SET field1='%s', field2='%s', field3='%s', field4='%s', field5='%s', field6='%s', field7='%s', field8='%s', field9='%s', field10='%s' WHERE id='%s'" % (var1, var2, var3, var4, var5, var6, var7, var8, var9, var10, id)
