To read data from a MySQL database in MATLAB, you need to use MATLAB’s Database Toolbox. Here is a simple example code demonstrating how to connect to a MySQL database and read data:<\/p>\n

% \u8fde\u63a5\u5230MySQL\u6570\u636e\u5e93
<\/p>
conn = database('database_name','username','password','com.mysql.jdbc.Driver','jdbc:mysql:\/\/hostname:port\/database_name');<\/p>
% \u67e5\u8be2\u6570\u636e\u5e93\u4e2d\u7684\u6570\u636e<\/p>
query = 'SELECT * FROM table_name';<\/p>
data = fetch(conn, query);<\/p>
% \u5173\u95ed\u6570\u636e\u5e93\u8fde\u63a5<\/p>
close(conn);<\/p><\/pre>\n
Please make sure to replace database_name with the name of your MySQL database, username and password with your MySQL username and password, hostname and port with the host name and port number of your MySQL server, and table_name with the name of the table from which you want to retrieve data. In the code above, the fetch function is used to execute the query and store the results in the data variable. You can modify the query statement as needed to retrieve the desired data. Then, use the close function to close the database connection. Note that using the Database Toolbox requires installing the appropriate driver. For MySQL databases, you need to install the MySQL Connector\/J driver. You can download and install this driver from the MySQL official website. Additionally, you can use the exec function to execute other types of SQL statements such as insert, update, and delete. When using the exec function, be mindful of the data type and format.<\/p>\n","protected":false},"excerpt":{"rendered":"
