Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE Customers ( Customer_ID INTEGER, Customer_Details VARCHAR(255) )
TABLE: CREATE TABLE Claims_Documents ( Claim_ID INTEGER, Document_Type_Code CHAR(15), Created_by_Staff_ID INTEGER, Created_Date INTEGER )
TABLE: CREATE TABLE Policies ( Policy_ID INTEGER, Customer_ID INTEGER, Policy_Type_Code CHAR(15), Start_Date DATETIME, End_Date DATETIME )
TABLE: CREATE TABLE Staff ( Staff_ID INTEGER, Staff_Details VARCHAR(255) )
TABLE: CREATE TABLE Claim_Headers ( Claim_Header_ID INTEGER, Claim_Status_Code CHAR(15), Claim_Type_Code CHAR(15), Policy_ID INTEGER, Date_of_Claim DATETIME, Date_of_Settlement DATETIME, Amount_Claimed DECIMAL(20,4), Amount_Piad DECIMAL(20,4) )
TABLE: CREATE TABLE Claims_Processing ( Claim_Processing_ID INTEGER, Claim_ID INTEGER, Claim_Outcome_Code CHAR(15), Claim_Stage_ID INTEGER, Staff_ID INTEGER )
TABLE: CREATE TABLE Claims_Processing_Stages ( Claim_Stage_ID INTEGER, Next_Claim_Stage_ID INTEGER, Claim_Status_Name VARCHAR(255), Claim_Status_Description VARCHAR(255) )
