這不起作用，並顯示錯誤“無法處理參數(shù)：str（在 Ponteland 提供優(yōu)質(zhì)輪胎服務(wù)），它必須是列表、元組或字典類型”

import mysql.connector
from sentence_splitter import SentenceSplitter, split_text_into_sentences

mydb = mysql.connector.connect(
  host="00.00.00.00",
  user="user",
  password="password",
  database="database"
)


mycursor = mydb.cursor()


sql = ("""SELECT blog_paragraph FROM blog_paragraph WHERE blog_topic like '%"%s"%'""")
val = ("Providing Quality Tyre Services in Ponteland")
mycursor.execute(sql,val)

myresult = mycursor.fetchall()

for x in myresult:
      print(x)

但是，當(dāng)直接在查詢中傳遞值時，它似乎運行時沒有任何錯誤。

import mysql.connector
from sentence_splitter import SentenceSplitter, split_text_into_sentences

mydb = mysql.connector.connect(
  host="00.00.00.00",
  user="user",
  password="password",
  database="database"
)


mycursor = mydb.cursor()


sql = ("""SELECT blog_paragraph FROM blog_paragraph WHERE blog_topic like '%"Providing Quality Tyre Services in Ponteland"%'""")
mycursor.execute(sql)

myresult = mycursor.fetchall()

for x in myresult:
      print(x)

嘗試透過變數(shù)傳遞字串參數(shù)，但似乎不起作用。

稍後找到答案

mycursor = mydb.cursor()

val = "Providing Quality Tyre Services in Ponteland"
sql = ("SELECT blog_paragraph FROM blog_paragraph WHERE blog_topic like '%%%s%%'  " % val)

mycursor.execute(sql)

myresult = mycursor.fetchall()
