将SQL Server 2000数据导入到MySQL 5.5的步骤
将SQL Server 2000数据导入到MySQL 5.5的方法 一、安装MySQL 5.5(可以与SQL Server不在同一台服务器上),并新建一个空的数据库(一般用utf-8编码),用于接收导入的数据。 二、在SQL Server的服务器上安装mysql-connector-odbc-5.3.2-win32。 三、在SQL Ser
将SQL Server 2000数据导入到MySQL 5.5的方法一、安装MySQL 5.5(可以与SQL Server不在同一台服务器上),并新建一个空的数据库(一般用utf-8编码),用于接收导入的数据。
二、在SQL Server的服务器上安装mysql-connector-odbc-5.3.2-win32。
三、在SQL Server的服务器上运行“管理工具”->“数据源(ODBC)”,切换到“系统DSN”面板,添加“MySQL ODBC 5.3 Unicode Driver”,填写“Data Source Name”为任意名称,填写“TCP/IP Server”和“Port”为MySQL数据库的IP和端口(一般为3306),再填写有数据库权限的用户和密码(一般为root用户,不装在本机的MySQL需要开通root远程访问权限),最后选择“Database”为第二步创建的数据库。
四、运行SQL Server的企业管理器,右键单击需要导出的数据库,在上下文菜单上选择“所有任务”->“导出数据”。点击下一步,先确认数据源的数据库名称是否正确(这一步一般选择Windows验证,也可以换成SQL Server身份验证)。再点击下一步,选择“目的”为“MySQL ODBC 5.3 Unicode Driver”,再选择“用户/系统 DSN”为第三步创建的Data Source。点击下一步,选择“从数据库复制表和视图”。点击下一步,在选择源表和视图中点击全选,点击下一步,然后立即执行。
五、数据导出成功后,SQL Server中的表字段为主键和自增量的字段不会在MySQL中设置成功。还需要回到MySQL,进行手工设置。可以使用Navicat MySQL图形工具或者执行SQL:
ALTER TABLE `users`
MODIFY COLUMN `id` int(11) NOT NULL AUTO_INCREMENT FIRST ,
ADD PRIMARY KEY (`id`);
我在导出数据的过程中,有些表在COPY数据时会发生错误。我遇到的错误和解决办法如下:
1、某个表的某个字段 cannot be null
在导出数据之前,先在SQL Server中将该表的该字段设置为“允许为NULL”
2、某个表的某个字段 Data too long for column 'name'
这种情况发生在安装了mysql-connector-odbc-5.1.2-win32,且SQL Server某记录存在中文乱码。改用mysql-connector-odbc-5.3.2-win32并选择MySQL ODBC 5.3 Unicode Driver后,问题解决。
3、某个表 id doesn't have a default value
查询Google,有解决办法禁用MySQL的strict Mode,参见:http://blog.csdn.net/god8816/article/details/8593419
其实只需要手工修改MySQL中该表的id字段为主键+Auto Increment,然后进入企业管理器,重新导出该表即可。

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

You can open phpMyAdmin through the following steps: 1. Log in to the website control panel; 2. Find and click the phpMyAdmin icon; 3. Enter MySQL credentials; 4. Click "Login".

Create a database using Navicat Premium: Connect to the database server and enter the connection parameters. Right-click on the server and select Create Database. Enter the name of the new database and the specified character set and collation. Connect to the new database and create the table in the Object Browser. Right-click on the table and select Insert Data to insert the data.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

You can create a new MySQL connection in Navicat by following the steps: Open the application and select New Connection (Ctrl N). Select "MySQL" as the connection type. Enter the hostname/IP address, port, username, and password. (Optional) Configure advanced options. Save the connection and enter the connection name.

Recovering deleted rows directly from the database is usually impossible unless there is a backup or transaction rollback mechanism. Key point: Transaction rollback: Execute ROLLBACK before the transaction is committed to recover data. Backup: Regular backup of the database can be used to quickly restore data. Database snapshot: You can create a read-only copy of the database and restore the data after the data is deleted accidentally. Use DELETE statement with caution: Check the conditions carefully to avoid accidentally deleting data. Use the WHERE clause: explicitly specify the data to be deleted. Use the test environment: Test before performing a DELETE operation.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.

As a data professional, you need to process large amounts of data from various sources. This can pose challenges to data management and analysis. Fortunately, two AWS services can help: AWS Glue and Amazon Athena.
