例子

远程测试如:mysqlslap -a -h"192.168.1.139" -P3306 -p指定sql语句 如:mysqlslap --create-schema=test -q"select * from user"自动测试 如:mysqlslap -a显示测试sql语句 如:mysqlslap -a --only-print

报表

我们测试本地数据库引擎性能
mysqlslap -a -e"myisam,innodb" --csv="c:/a.csv"

c:/a.csv文件 /

我们转换成图表形式 /
可以看出 myisam,innodb 混合测试时myisam性能更好些 读写时间更少

常用选项

Windows默认配置文件读取顺序:
C:/WINDOWS/my.ini
C:/WINDOWS/my.cnf
C:/my.ini
C:/my.cnf
F:/mysql/5.6.16/my.ini
F:/mysql/5.6.16/my.cnf


-h 数据库host
-u 数据库用户名
-p 数据库密码
-P 数据库端口


--create-schema=name 测试的数据名
--create=name 测试的SQL语句或文件
--no-drop 测试后不删除schema
--only-print 仅显示将被运行的SQL语句


-c 客户端数量(并发量) 如:mysqlslap -c"10"或-c"10,100,1000"
-e 测试引擎 如:mysqlslap -e"myisam"或-e"myisam,innodb"
--number-of-queries=# SQL语句执行总次数 如:mysqlslap -a --number-of-queries="10"
-q 测试的SQL语句 如:mysqlslap -q"SELECT * FROM t1"
-i 迭代运行次数 如:mysqlslap -a -i"3"
-T 显示内存和CPU信息并退出 如:mysqlslap -a -T
-F SQL语句分隔符
-s 不输出无回显运行


--csv[=name] 生产CSV格式数据文件
--commit=# 设置每多少条sql语句提交一次
--detach=# 设置每多少条sql语句重连服务器一次

-a,--auto-generate-sql 自动生成MySQL测试语句
--auto-generate-sql-add-autoincrement 添加AUTO_INCREMENT字段
--auto-generate-sql-execute-number=# 查询的个数
--auto-generate-sql-guid-primary 添加GUID字段
--auto-generate-sql-load-type=name mixed:混合、update:更新、write:写入、key:读主键、read:查询
--auto-generate-sql-secondary-indexes=# 设置索引字段个数
--auto-generate-sql-unique-query-number=# 生成N条不同的query sql语句
--auto-generate-sql-unique-write-number=# 生成N条不同的write sql语句

How do you handle database upgrades in MySQL?How do you handle database upgrades in MySQL?Apr 30, 2025 am 12:28 AM

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

What are the different backup strategies you can use for MySQL?What are the different backup strategies you can use for MySQL?Apr 30, 2025 am 12:28 AM

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

How do you optimize database schema design for performance in MySQL?How do you optimize database schema design for performance in MySQL?Apr 30, 2025 am 12:27 AM

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

How to use MySQL functions for data processing and calculationHow to use MySQL functions for data processing and calculationApr 29, 2025 pm 04:21 PM

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

An efficient way to batch insert data in MySQLAn efficient way to batch insert data in MySQLApr 29, 2025 pm 04:18 PM

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

Steps to add and delete fields to MySQL tablesSteps to add and delete fields to MySQL tablesApr 29, 2025 pm 04:15 PM

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
