Create, configure, test, and save a PostgreSQL native interface data source for a PostgreSQL database.

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

vendor = "PostgreSQL";
opts = databaseConnectionOptions("native",vendor)
opts = 
  SQLConnectionOptions with properties:

              DataSourceName: ""
                      Vendor: "PostgreSQL"

                DatabaseName: ""
                      Server: "localhost"
                  PortNumber: 5432

opts is an SQLConnectionOptions object with these properties:

  • DataSourceName — Name of the data source

  • Vendor — Database vendor name

  • DatabaseName — Name of the database

  • Server — Name of the database server

  • PortNumber — Port number

Configure the data source by setting the database connection options for the data source PostgreSQLDataSource, database name toystore_doc, database server dbtb00, and port number 5432.

opts = setoptions(opts, ...
    'DataSourceName',"PostgreSQLDataSource", ...
    'DatabaseName',"toystore_doc",'Server',"dbtb00", ...
    'PortNumber',5432)
opts = 
  SQLConnectionOptions with properties:

              DataSourceName: "PostgreSQLDataSource"
                      Vendor: "PostgreSQL"

                DatabaseName: "toystore_doc"
                      Server: "dbtb00"
                  PortNumber: 5432

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 = "dbdev";
password = "matlab";
status = testConnection(opts,username,password)
status = logical
   1

Save the configured data source.

saveAsDataSource(opts)

You can connect to the new data source using the postgresql function or the Database Explorer app.

Edit an existing PostgreSQL native interface data source for a PostgreSQL database. Set an additional driver-specific option and save the data source.

Retrieve the existing PostgreSQL data source PostgreSQLDataSource.

datasource = "PostgreSQLDataSource";
opts = databaseConnectionOptions(datasource)
opts = 
  SQLConnectionOptions with properties:

              DataSourceName: "PostgreSQLDataSource"
                      Vendor: "PostgreSQL"

                DatabaseName: "toystore_doc"
                      Server: "dbtb00"
                  PortNumber: 5432

opts is an SQLConnectionOptions object with these properties:

  • DataSourceName — Name of the data source

  • Vendor — Database vendor name

  • DatabaseName — Name of the database

  • Server — Name of the database server

  • PortNumber — Port number

Add a driver-specific connection option by using a name-value pair argument. The option specifies a timeout value for establishing the database connection. opts contains a new section of properties for the additional connection option.

opts = setoptions(opts,"connect_timeout",20)
opts = 
  SQLConnectionOptions with properties:

              DataSourceName: "PostgreSQLDataSource"
                      Vendor: "PostgreSQL"

                DatabaseName: "toystore_doc"
                      Server: "dbtb00"
                  PortNumber: 5432

	Additional Connection Options:

             connect_timeout: 20

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 = "dbdev";
password = "matlab";
status = testConnection(opts,username,password)
status = logical
   1

Save the updated data source.

saveAsDataSource(opts)

Input Arguments

collapse all

Database connection options, specified as an SQLConnectionOptions object.

PostgreSQL native interface connection options, specified as one or more name-value pair arguments. Option is a character vector or string scalar that specifies the name of a PostgreSQL native interface connection option. OptionValue specifies the value of the option. OptionValue can be a character vector, string scalar, logical scalar, or numeric scalar. You can specify any PostgreSQL native interface connection option that is a property of the SQLConnectionOptions object.

Example: 'DataSourceName',"myDataSource",'Server',"localhost",'PortNumber',5432 configures a PostgreSQL native interface data source named myDataSource that is located on the local server with the port number 5432.

Output Arguments
