SQLite3 OperationalError：“（”附近：语法错误

Question

我到处都看过，无法弄清楚为什么它不起作用。

import sqlite3

path = '/Users/...'
con = sqlite3.connect(path+'YSD.sqlite')
cur = con.cursor()
cmd = 'SELECT ISD_NAME replace(ISD_NAME,"Statewide"," Statewide") FROM enr'
cur.execute(cmd)
con.commit()
con.close()

OperationalError: near "(": syntax error

我也尝试过这个，但无济于事：

cmd = 'SELECT ISD_NAME replace(ISD_NAME,?,?) FROM enr'
cur.execute(cmd, ("\"Statewide\"","\" Statewide\""))

Answer 1

如果您要获取ISD_NAME列值，并用“ Statewide” 替换“ Statewide” ，请在{{1}之后删除ISD_NAME }。

例如，假设您有一个这样的表：

SELECT

您的脚本变为：

CREATE TABLE enr("id" PRIMARY KEY, "ISD_NAME" VARCHAR);
INSERT INTO enr VALUES (1, "somethingStatewide");

打印测试：

cmd = 'SELECT replace(ISD_NAME,"Statewide"," Statewide") FROM enr'
cur.execute(cmd)

结果在这里：

records = cur.fetchall()
print(records)
