Examples
Create PostgreSQL Native Interface Data Source
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 sourceVendor
— Database vendor nameDatabaseName
— Name of the databaseServer
— Name of the database serverPortNumber
— 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 Existing PostgreSQL Native Interface Data Source
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 sourceVendor
— Database vendor nameDatabaseName
— Name of the databaseServer
— Name of the database serverPortNumber
— 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
opts
— Database connection options
SQLConnectionOptions
object
Database connection options, specified as an SQLConnectionOptions
object.
Option1,OptionValue1,...,OptionN,OptionValueN
— PostgreSQL native interface connection options
name-value pair arguments
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
opts
— Database connection options
SQLConnectionOptions
object
Database connection options, returned as an SQLConnectionOptions
object.
