SQL:FullTextQuery Event Class
Applies to: 
SQL Server
Azure SQL Database
Azure SQL Managed Instance
The SQL:FullTextQuery event class occurs when SQL Server executes a full text query. Include this event class in traces that are monitoring problems associated with full text catalogs.
When the SQL:FullTextQuery event class is included, the amount of overhead will be high. If such events occur frequently, the trace may significantly impede performance. To minimize this, limit the use of this event class to traces that monitor specific problems for brief periods of time.
SQL:FullTextQuery Event Class Data Columns
| Data column name | Data type | Description | Column ID | Filterable |

| DatabaseID | int | ID of the database specified by the USE database statement or the default database if no USE databasestatement has been issued for a given instance. SQL Server Profiler displays the name of the database if the ServerName data column is captured in the trace and the server is available. Determine the value for a database by using the DB_ID function. | 3 | Yes |
