Field category search for Bloomberg Server connection V3

Syntax

d = category(c,f)

Description

d = category(c,f) returns category information given the search term f using the Bloomberg^® Server C++ interface.

Examples

Search for Bloomberg Last Price Field

Create a Bloomberg connection, and then request the category description of the last price field.

Connect to the Bloomberg Server using the IP address of the machine running the Bloomberg Server. This example uses the Bloomberg Server C++ interface and assumes the following:

• The Bloomberg UUID is 12345678.

• The IP address for the machine running the Bloomberg Server is '111.11.11.111'.

c is a bloombergServer object.

uuid = 12345678;
ipaddress = '111.11.11.111';

c = bloombergServer(uuid,ipaddress);

Return data as a table by setting the DataReturnFormat property of the bloomberg object. If you do not set this property, the category function returns data as a cell array.

c.DataReturnFormat = 'table';

Request the Bloomberg category description of the last price field.

f = 'LAST_PRICE';
d = category(c,f);

Display the first three rows of the Bloomberg category description data in d.

d(1:3,:)
