-|_COLUMN_NAME_|The variable name is the source column name in uppercase of the row being changed (replace COLUMN_NAME with your column)
+|_<COLUMN_NAME>_|The variable name is the source column name in uppercase of the row being changed (replace <COLUMN_NAME> with your column)
 |currentValue|The value of the current source column
 |oldValue|The old value of the source column for an updated row
-|sqlTemplate|a org.jumpmind.db.sql.ISqlTemplate object for querying or updating the database
-|channelId|a reference to the channel on which the transformation is happening
-|sourceNode|a org.jumpmind.symmetric.model.Node object that represents the node from where the data came
