getConnections: Gets the connections

This command gets the specified connections in the database.

Result set columns: Ordered by NAME.

Name	Data Type	Description
NAME	string	connection name
CREATED	string	when the connection was created
COMMENT	string	connection comment

If the command returns a result set which has less than 1,000 rows of data, the data will be provided in the data field of resultSet. However if the command returns a result set which has 1,000 or more rows of data, a result set will be opened whose handle is returned in the resultSetHandle field of resultSet. Using this handle, the data from the result set can be retrieved using the fetch command. Once the result set is no longer needed, it should be closed using the closeResultSet command.

Request fields:

• command (string) => command name: "getConnections"
• attributes (object, optional) => attributes to set for the connection (see Attributes)
• name (string, optional) => connection name. "" means no connection, null means all connections.
