Sql query to fetch Defect 'Fixed By' & 'Date/Time' for the field name: 'Defect Status' in HISTORY



I'm on AGM 2.57 version. Can anyone please let me know the relevant tables in AGM if not the complete sql query. I would like to know if there is any sql query in Agile Manager to extract from the database who fixed the defect by leveraging 'Old Value' and 'New Value' columns by selecting the field name: 'Defect Status' in the HISTORY section. If the 'New Value' is "Fixed", I would like to capture the 'Changer' and 'Date/Time' in the report using sql query. 


Thanks in advance!
