reset

Create, configure, and test a MySQL® native interface data source for a MySQL database. Reset the database connection options to their default values. Then configure, test, and save the data source with different database connection options.

Create a MySQL native interface data source for a MySQL database connection.

vendor = "MySQL";
opts = databaseConnectionOptions("native",vendor)

opts = 
  SQLConnectionOptions with properties:

              DataSourceName: ""
                      Vendor: "MySQL"

                DatabaseName: ""
                      Server: "localhost"
                  PortNumber: 3306

opts is an SQLConnectionOptions object with these properties:

Configure the data source by setting the database connection options for the data source MySQLDataSource, database name toystore_doc, database server dbtb01, and port number 3306.

opts = setoptions(opts, ...
    'DataSourceName',"MySQLDataSource", ...
    'DatabaseName',"toystore_doc",'Server',"dbtb01", ...
    'PortNumber',3306)

opts = 
  SQLConnectionOptions with properties:

              DataSourceName: "MySQLDataSource"
                      Vendor: "MySQL"

                DatabaseName: "toystore_doc"
                      Server: "dbtb01"
                  PortNumber: 3306

The setoptions function sets the DataSourceName, DatabaseName, Server, and PortNumber properties in the SQLConnectionOptions object.

Test the database connection with a user name and password. The testConnection function returns the logical 1, which indicates the database connection is successful.

username = "root";
password = "matlab";
status = testConnection(opts,username,password)

status = logical
   1

Reset the database connection options to their default values.

opts = reset(opts)

opts = 
  SQLConnectionOptions with properties:

              DataSourceName: ""
                      Vendor: "MySQL"

                DatabaseName: ""
                      Server: "localhost"
                  PortNumber: 3306

Configure the data source again by setting the database connection options for the data source MySQLDataSource, database name toystore_doc, database server dbtb01, and port number 3306. Also, set a driver-specific connection option to specify a timeout value for establishing the database connection.

opts = setoptions(opts, ...
    "DataSourceName","MySQLDataSource", ...
    "DatabaseName","toystore_doc", ...
    "Server","dbtb01","PortNumber",3306, ...
    "OPT_CONNECT_TIMEOUT",20)

opts = 
  SQLConnectionOptions with properties:

              DataSourceName: "MySQLDataSource"
                      Vendor: "MySQL"

                DatabaseName: "toystore_doc"
                      Server: "dbtb01"
                  PortNumber: 3306

	Additional Connection Options:

         OPT_CONNECT_TIMEOUT: 20

The setoptions function sets the DataSourceName, DatabaseName, Server, and PortNumber properties in the SQLConnectionOptions object. The driver-specific connection option appears below the other connection options.

Test the database connection again.

username = "root";
password = "matlab";
status = testConnection(opts,username,password)

status = logical
   1

Save the configured data source.
