通过拖拽自动生成sql_oracle中如何通过已有的表生成相关sql语句

1. 处理数据批量生成sql插入语句

处理数据批量生成sql插入语句
最近在做一个天气预报模块，首先需要将客户端公网ip转换成所在城市，然后将所在城市名转换成对应的城市代码，在网上找到了城市代码，但是需要处理一下，看了看，有三百多城市及对应的城市代码，想存到数据库。就想着做一个数据处理自动生成sql语句的工具，提高效率。

城市代码

一看上去很乱的，而且对应关系是每个省城市一行，代码一行，分别用引号引起，用逗号分隔，每行间都没有符号分隔，省名没有用引号。首先是想着把省名去掉，因为每个城市名都是不相同的。想着每两行两行的去处理，但是也要费不少功夫，还容易出错。就想个索性一次性的全处理的算法。

ps：界面很简单，上面是输入数据，中间是转换，下面是输出数据。

后台主要代码：
[csharp] view plain

private void button1_Click(object sender, EventArgs e)
{
string data = textBox1.Text.Replace("r", "").Replace("n", "").Replace("t", "").Replace(" ", "").Replace(" ", "").Replace(" ", "");
MatchCollection matchsdata = matches(data, ""[sS]*?"");
string[,] temps = new string[matchsdata.Count / 2, 2];
int count0 = 0;
int count1 = 0;
string input = string.Empty;
foreach (Match m in matchsdata)
{
string tempdata = m.Value.Replace(""", "");
try
{
int tryp = int.Parse(tempdata);
temps[count1, 1] = tempdata;
count1++;
}
catch (Exception ex)
{
temps[count0, 0] = tempdata;
count0++;
}
}
for (int i = 0; i < (matchsdata.Count / 2); i++)
{
input += "insert into tbl_CityCode(c_city,c_code) values( + temps[i, 0] + , + temps[i, 1] + )rn";
}
textBox2.Text = input;
}

public static MatchCollection matches(string str, string exp)
{
return Regex.Matches(str, exp, RegexOptions.IgnoreCase);
}

首先是将输入的数据处理，去除换行符，空格什么的。然后你应该是会得到一行数据，然后通过正则表达式匹配出所有带引号的数据，你会发现需要的数据全部都是用引号引起来的，但是怎样区分城市名和城市代码呢，它们是混在一起的。不用担心，你发现了吗？城市名是字符串，城市代码是一串数字，我们只要将匹配出的数据数组遍历，每一行数据都去转换成int类型，这样城市名的行就会报错，在catch中捕捉，这一行就是城市名，没错的就是城市代码，把数据一次存到一个二维数组，对应的列中就行了。这样就会获得了相对应的城市名和城市代码。生成的sql语句要对应相应的数据库表。
表结构：
转换完了将生成的sql语句放到查询器中执行就ok了。共处理了349个城市。
最后不放心自己的算法，随机抽查了几条数据，没有错误。

2. java如何根据实体类图生成sql脚本

自动生成C#和Java实体类，自动生连接符为“&”和“+”的INSERT,UPDATE,DELETE,SELECT语句，支持简单的数据查询修改。

3. oracle中如何通过已有的表生成相关sql语句

最简单的方法，通过第三方工具plsql。

步骤：

1、登录表所在数据库及用户。

4. 怎么创建数据库

问题一：创建数据库的两种方法交互式创建，就是你右击数据库然后选择新建数据库按钮就可以.....还有一种就是sql语句创建比如创建一个数据库名为a 的数据库，那么sql语句就是，create database a;然后执行下就可以...

问题二：如何用MySQL建立数据库这很简单啊！
在Windows下，假如你的MySQL装在 D:\MySQL
就可以这样：
先切换到它的bin目录
cd D:\MySQL\bin\
抚:\MySQL\bin>mysql -u root -p
接着输入你的root密码
接下来你就可以创建数据库、创建用户、创建修改表之类的操作（常用命令如下）。
查看现有数据库
mysql> show databases;
创建数据库(假如数据库名为 mydb)
mysql> create database mydb;
删除数据库（假如数据库名为 mydb）
mysql> drop database accounts;
使用数据库（假如使用数据库 mydb）
mysql> use mydb;
执行完使用数据库命令后，就可以对该数据库进行创建、修改、插入、删除表等操作，这些表的操作命令你可以到网上找找，不是很难的。一个数据库就相当于一个 Excel 文件，而表则相当于Excel文件的单元格，数据就是存放在表中。

问题三：怎样建立一个简单数据库？把excel导入数据库，不出现表格嵌套可以使用下面这个方法导入；
思路：
(1)、把excel数据读入到dataset中；
(2)、建立相应结构的数据表格
(3)、把dat畅set中的数据更新到数据表中

问题四：如何用数据库向导创建数据库 Microsoft Access 提供了三种方法来创建 Access 数据库（Microsoft Access 数据库：数据和对象（如表、查询或窗体）组成的 *** ，与特定的主题或用途有关。）。
可以使用“数据库向导”来创建数据库。通过该向导可以从内置模板中进行选择，然后对其进行一定程度的自定义。随后，该向导会为数据库创建一组表、查询、窗体和报表，同时还会创建切换面板。表中不含任何数据。如果内置模板中的某个模板非常符合您的要求，请使用该方法。
使用“数据库向导”创建数据库
利用“数据库向导”，用一步操作即可为所选数据库类型创建必需的表、窗体和报表。这是创建数据库的最简单方法。该向导提供了有限的选项来自定义数据库。
单击工具栏上的“新建”。
在“新建文件”任务窗格中，在“模板”下，单击“本机上的模板”。
在“数据库”选项卡上，单击要创建的数据库类型的图标，然后单击“确定”。
在“文件新建数据库”对话框中，指定数据库的名称和位置，然后单击“创建”。
按照“数据库向导”的指导进行操作。
如果向导未启动
这可能是因为 Access 正运行于沙盒模式，但您的计算机上尚未安装 Microsoft Jet 4.0 SP8 或更高版本。启用沙盒模式后，必须安装有 Jet 4.0 SP8 或更高版本，Access 才能完全发挥作用。
有关安装 Jet 升级的详细信息，请参阅 Office Online 文章关于 Microsoft Jet 4.0 SP8 或更高版本。
有关沙盒模式的详细信息，请参阅 Office Online 文章关于 Microsoft Jet Expression Service 沙盒模式。
注释不能使用“数据库向导”向已有的数据库中添加新的表、窗体或报表。
如果正在使用 Access 2003，可以在中搜索 Access 模板。下载模板是创建数据库的最快方式。如果您找到了非常符合要求的模板，请使用该方法。模板是一个包含表、查询、窗体和报表的 Access 数据库文件 (*.mdb)。表中不含任何数据。打开数据库后，可以自定义数据库和对象。
使用模板创建数据库
这是创建数据库的最快方式。如果能找到并使用与您的要求非常接近的模板，则此方法效果最佳。
在工具栏上单击“新建”。
在“新建文件”任务窗格中，在“模板”下，搜索特定的模板，或单击“Office Online 模板”找到合适的模板。
找到需要的 Access 模板，然后单击“下载”。
如果要基于自己的设计创建数据库，请先创建一个空数据库，然后再分别添加表、窗体、报表及其他对象。这是最灵活的方法，但需要分别定义每一个数据库元素。
不使用“数据库向导”创建空数据库
单击工具栏上的“新建”。
在“新建文件”任务窗格中的“新建”下，单击“空数据库”。
在“文件新建数据库”对话框中，指定数据库的名称和位置，然后单击“创建”。
然后将出现“数据库”窗口（数据库窗口：在打开 Access 数据库或 Access 项目时出现的窗口。它显示用于新建数据库对象和打开现有对象的快捷方式。），现在便可以在数据库中创建所需的对象（数据库对象：Access 数据库包含诸如表、查询、窗体、报表、页、宏和模块等对象；Access 项目包含诸如窗体、报表、页、宏和模块等对象。）。...>>

问题五：怎样在mysql中创建数据库是这句：创建一个数据库MYSQLDATA
mysql> CREATE DATABASE MYSQLDATA;
基本操作：MySQL中新建用户,新建数据库,用户授权,删除用户,修改密码的相关操作测试环境：WIN32 mysql5.0.45注：本操作是在WIN命令提示符下，phpMyAdmin同样适用。
用户：phplamp 用户数据库：phplampDB1.新建用户。登录MYSQL
@>mysql -u root -p
@>密码
创建用户
mysql> insert into mysql.user(Host,User,Password) values(localhost,phplamp,password(1234));
刷新系统权限表
mysql>flush privileges;
这样就创建了一个名为：phplamp 密码为：1234 的用户。然后登录一下。mysql>exit;
@>mysql -u phplamp -p
@>输入密码
mysql>登录成功2.为用户授权。登录MYSQL（有ROOT权限）。我里我以ROOT身份登录.
@>mysql -u root -p
@>密码
首先为用户创建一个数据库(phplampDB)
mysql>create database phplampDB;
授权phplamp用户拥有phplamp数据库的所有权限。
>grant all privileges on phplampDB.* to identified by '1234';
刷新系统权限表
mysql>flush privileges;
mysql>其它操作/*
如果想指定部分权限给一用户，可以这样来写:
mysql>grant select,update on phplampDB.* to identified by '1234';
刷新系统权限表。
mysql>flush privileges;
*/3.删除用户。@>mysql -u root -p
@>密码
mysql>DELETE FROM user WHERE User=phplamp and Host=localhost;
mysql>flush privileges;
删除用户的数据库
mysql>drop database phplampDB;4.修改指定用户密码。@>mysql -u root -p
@>密码
mysql>update mysql.user set password=password('新密码') where User=phplamp and Host=localhost;
mysql>flush privileges;5.列出所有数据库mysql>show database;6.切换数据库mysql>use '数据库名';7.列出所有表mysql>show t......>>

问题六：怎么创建数据库连接方法一、通过编写代码来连接数据库
1定义连接字符串。Data Source=服务器;Initial Catalog=数据库名;User ID=用户名;Pwd=密码如：Data Source=IDEA-PC\SQLEXPRESS;Initial Catalog=student;User ID=sa;
2创建Connection对象。 SqlConnection sqlconnection1=new SqlConnection(constring);
constring为连接字符串。
3打开与数据库的链接。 Sqlconnection1.Open();
4这时数据库就连接成功，可以操作数据库了。
方法二、通过拖拽形式建立数据库连接
1打开视图-->服务器资源管理器。
2右键点就数据连接，选择添加连接。
3选择服务器名（先刷新一下）-->登陆到服务器身份验证形式-->选择一个数据库名-->测试链接-->确定（如果测试链接成功的话）。
4这是建立数据库连接就成功了，可以使用了。

问题七：sqlserver 下怎么建立数据库怎么建表方法/步骤
1
首先我们打开SQL SERVER自带的数据库管理工具，从开始菜单中可以找到，如图点击进去；
2
开始连接SQL SERVER服务器，就是我们装好的SQL SERVER 服务器；
3
右击数据库，选择第一个，新建一个数据库；
4
填写数据库的名称，下面是设置自动增长的，一般不用管，默认
5
点击确定后就可以生成一个数据库，此时里面是没有表的；
6
右击表新建一个表，填写你要的字段名称
7
填完字段名称后点击字段名称那个内部窗口的小叉叉，然后就提示你输入表名了，填写下表名，一个数据库的建立过程就是这样的；
或者
create database stuDB
on primary -- 默认就属于primary文件组,可省略
(
/*--数据文件的具体描述--*/
name='stuDB_data', -- 主数据文件的逻辑名称
filename='D:\stuDB_data.mdf', -- 主数据文件的物理名称
size=5mb, --主数据文件的初始大小
maxsize=100mb, -- 主数据文件增长的最大值
filegrowth=15%--主数据文件的增长率
)
log on
(
/*--日志文件的具体描述,各参数含义同上--*/
name='stuDB_log',
filename='D:\stuDB_log.ldf',
size=2mb,
filegrowth=1mb
)

问题八：oracle数据库怎么创建新用户？在CRT中进入oracle --连接sqlplus
按照下面写完代码直接复制进去回车就行了
---建立用户代码为：CREATE USER 用户名字 PROFILE DEFAULT IDENTIFIED BY 密码 DEFAULT TABLESPACE 指定表空间名字 TEMPORARY TABLESPACE 临时表空间 ACCOUNT UNLOCK;
---赋权
begin
EXECUTE IMMEDIATE 'GRA�T SELECT ANY DICTIONARY TO 用户名';
EXECUTE IMMEDIATE 'GRANT ALTER ANY TABLE TO 用户名';
EXECUTE IMMEDIATE 'GRANT ALTER SYSTEM TO 用户名';
EXECUTE IMMEDIATE 'GRANT ALTER ANY PROCEDURE TO 用户名';
EXECUTE IMMEDIATE 'GRANT CONNECT TO 用户名';
EXECUTE IMMEDIATE 'GRANT CREATE ANY PROCEDURE TO 用户名';
EXECUTE IMMEDIATE 'GRANT CREATE ANY TABLE TO 用户名';
EXECUTE IMMEDIATE 'GRANT CREATE ANY INDEX TO 用户名';
EXECUTE IMMEDIATE 'GRANT CREATE DATABASE LINK TO 用户名';
EXECUTE IMMEDIATE 'GRANT CREATE PUBLIC DATABASE LINK TO 用户名';
EXECUTE IMMEDIATE 'GRANT CREATE ANY VIEW TO 用户名';
EXECUTE IMMEDIATE 'GRANT CREATE PUBLIC SYNONYM TO 用户名';
EXECUTE IMMEDIATE 'GRANT CREATE TABLE TO 用户名';
EXECUTE IMMEDIATE 'GRANT DELETE ANY TABLE TO 用户名';
EXECUTE IMMEDIATE 'GRANT DROP PUBLIC DATABASE LINK TO 用户名';
EXECUTE IMMEDIATE 'GRANT DROP ANY TRIGGER TO 用户名';
EXECUTE IMMEDIATE 'GRANT DROP ANY INDEX TO 用户名';
EXECUTE IMMEDIATE 'GRANT DROP ANY PROCEDURE TO 用户名';
EXECUTE IMMEDIATE 'GRANT DROP ANY TABLE TO 用户名';
EXECUTE IMMEDIATE 'GRANT DROP ANY VIEW TO 用户名';
