Not sure but if you are asking TSQL command to enable FULL TEXT search on your table then you can use the below TSQL queries for the same
use [DB_NAME]
CREATE FULLTEXT CATALOG productcat AS DEFAULT;
GO
EXEC [DB_NAME].[dbo].[sp_fulltext_database] @action = 'enable'
GO
(OR)
USE [DB_NAME];
GO
CREATE FULLTEXT CATALOG productcat;
GO
CREATE FULLTEXT INDEX ON Products
(
Name
Language 1033,
ModelNumber
Language 1033
)
KEY INDEX PK_Products_ProductName
ON productcat;
GO
See CREATE FULLTEXT INDEX (Transact-SQL) for more information
EDIT:
In case you want to know whether FULL TEXT is installed or not; you can use below command
select SERVERPROPERTY('IsFullTextInstalled')
If the above query returns a 1 then the component is installed.
In case you want to check whether a particular table has FULL TEXT enabled
SELECT OBJECTPROPERTYEX(OBJECT_ID('Products'), 'TableHasActiveFulltextIndex');
GO
