MSSQL转MYSQL,gb2312转utf-8无乱码解决方法
MSSQL转MYSQL,gb2312转utf-8无乱码解决方法,需要的朋友可以参考下。
使用软件:MySQLMigrationTool提示数据过大,无法导入。修改my.cnf文件的max_allowed_packet = 100M以上。在windows操作系统中,my.cnf有可能显示不出来,需要用编辑器直接输入地址:盘符:\目录mysql教程binmy.cnf打开。
“there can be only one TIMESTAMP column with CURRENT_TIMESTAMP in DEFAULT or ON UPDATE clause”,MSSQL一个表中有两个以上的日期时间字段使用了getdate()取默认值,去掉即可。
“BLOB/TEXT column '表名' can't have a default value”,此字段不允许使用默认值,去掉即可。
“The maximum row size for the used table type, not counting BLOBs, is 65535. You have to change some columns to TEXT or BLOBs”,此表字段占用空间太大,适当减少其字段数量或长度。
运行软件后,点NEXT进入以下界面:
选择MS SQL SERVER,按提示填写,Connection String为:
jdbc:jtds:sqlserver://IP地址:端口(默认1433)/数据库教程名;user=用户名;password=密码;charset=gb2312;domain=
下一步为MySQL的信息,Connection String为:
jdbc:mysql://IP地址:端口(默认3306)/?user=用户名&password=密码&useServerPrepStmts=false&<br>characterEncoding=UTF-8
之后一路按提示进行。到此界面选择要忽略的表。
继续NEXT,如图所示进入此界面,此处设定字符编码,非常关键。

有的同学运行后导入mysql的结果是中文乱码 , 那是由于在一路next的中间有一个
选择编码的步骤, 此处务必选 user defined ,填上 charset=gbk,coll...tion的等于
gbk_chinese_ci , 就是把latin,和swidish的修改下,改成中文相应的。总之这里要看好
否则乱码就怪不了别人了。
然后一路next就是了。。。。

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".

MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.

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.

MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

Effective monitoring of Redis databases is critical to maintaining optimal performance, identifying potential bottlenecks, and ensuring overall system reliability. Redis Exporter Service is a powerful utility designed to monitor Redis databases using Prometheus. This tutorial will guide you through the complete setup and configuration of Redis Exporter Service, ensuring you seamlessly build monitoring solutions. By studying this tutorial, you will achieve fully operational monitoring settings

The methods for viewing SQL database errors are: 1. View error messages directly; 2. Use SHOW ERRORS and SHOW WARNINGS commands; 3. Access the error log; 4. Use error codes to find the cause of the error; 5. Check the database connection and query syntax; 6. Use debugging tools.

Apache connects to a database requires the following steps: Install the database driver. Configure the web.xml file to create a connection pool. Create a JDBC data source and specify the connection settings. Use the JDBC API to access the database from Java code, including getting connections, creating statements, binding parameters, executing queries or updates, and processing results.
