    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT SUM(T3.amount) FROM client AS T1 INNER JOIN disp AS T4 ON T1.client_id = T4.client_id INNER JOIN account AS T2 ON T4.account_id = T2.account_id INNER JOIN trans AS T3 ON T2.account_id = T3.account_id WHERE STRFTIME('%Y', T3.date)= '1998' AND T1.client_id = 617
