DROP FULLTEXT INDEX (Transact-SQL)
DROP FULLTEXT INDEX ON table_name
Is the name of the table or indexed view containing the full-text index to be removed.
You do not need to drop all columns from the full-text index before using the DROP FULLTEXT INDEX command.
The user must have ALTER permission on the table or indexed view, or be a member of the sysadmin fixed server role, or db_owner or db_ddladmin fixed database roles.
The following example drops the full-text index that exists on the JobCandidate table.
DROP FULLTEXT INDEX ON HumanResources.JobCandidate;
