我想创建自己的模块来返回Mysql游标,但是我的模块依赖于import mysql.connector和from mysql.connector import Error。 我该如何解决这个问题?是否与__init__.py文件的目录位置有关?我去叫NameError: name 'mysql' is not defined。 from mysql import connector
from mysql.connector import Error
class SqlCnt:
def __init__(self, db):
""
import _mysql as mysql
db=mysql.connect('localhost','username','password','database')
db.query("""select * from news""")
result = db.store_result()
print result.num_rows()#two records
#how to loop? without cursor
print result.fetch_row()
我是node.js的新手。我有两个文件。他们是index.js和db.js
我的index.js是
var connection = require('./db.js');
device = new Device({
id: 93,
name: 'test1'
});
device.save();
我的db.js是
var mysql = require('mysql2');
var mysqlModel = require('mysql-model');
var appModel = mysqlM
我试图模拟一个数据库调用,它一直导致db函数返回未定义的。
请看一下我的档案。
db.ts
import * as mysql from "mysql";
import * as util from "util";
{... other functions with named exports}
const getDbConnection = () => {
const pool = mysql.createPool(DB_CONFIG);
return {
query(sql: string) {
return util.
我正在尝试使用php将印地语数据导出到excel中。输出印地语数据后,会以不同的格式显示“?”。我以前的代码是
<?php
include 'config.php';
setlocale(LC_ALL, "en_US.UTF-8");
$DB_TBLName = "feedback"; //MySQL Table Name
$filename = "feedback"; //File Name
/*******YOU DO NOT NEED TO EDIT ANYTHING BELOW THIS LIN
我保存了一个用于构建站点的sql导入文件,在升级到ddev v0.19.0之后,当我执行`ddev import-db -src=..tarballs/d7git.sql.gz时,我得到了这个文件:

整个项目- (配置文件已过时)
这是配置文件:

class Config {

const PATH_TO_SQLITE_FILE = 'db/DeviceAssetRegister.db';
}
