问题 I have to retrieve all clients linked via loans by giving only one as input. Example I have a table data as TABLEA LOAN_ID CLIENT_ID 1 7 1 8 2 7 4 8 4 9 4 10 5 9 5 11 13 2 14 3 If I have given only input as CLIENT_ID=7 then the query has to select all the columns from above table except last two column because client_id 7 has 1,2 LOAN_ID and in 1 the CLIENT_ID 8 has loan_id=4 and in this loan CLIENT_id 9 has again 5 as loan_id. can we write a sql query for this without stored procedure in DB2
