 Custom Query
 -------------
-A custom query is supported to bring the possibility of use entire SQL languaje. This is powerfull, but risky, be carefull with the custom queries.
-To use is needed an special character '@' to indicate where the incremental value should be.
+A custom query is supported to bring the possibility of use entire SQL languaje. This is powerfull, but risky, be carefull with the custom queries used.
+
 Example:
 ```
-agent.sources.sql-source.custom.query = SELECT field1,field2 FROM table1 WHERE field1='test' AND @ ORDER BY field2;
+agent.sources.sql-source.custom.query = SELECT field1,field2 FROM table1 WHERE field1='test'
 ```
-Will run the query:  
-```SELECT field1,field2 FROM table1 WHERE field1='test' AND incrementalColumn > 0 ORDER BY field2;```
