org.apache.derby.iapi.sql.dictionary.TabInfo.deleteRow()
Given a key row, delete all matching heap rows and their index rows.
LOCKING: row locking if there is a key; otherwise, table locking. @param tc transaction controller @param key key to delete by. @param indexNumber Key is appropriate for this index. @return the number of rows deleted. If key is not unique,this may be more than one. @exception StandardException Thrown on failure
