I tried to join 3 tables all together but when I execute the query only the first row on the table is displayed. The table consists of many rows. How can I display multiple rows?
This is the code that I tried
SELECT l.id,m.name,b.bookname,l.issuedate,l.returndate FROM lend l INNER JOIN member m on l.memberid = m.id INNER JOIN books b ON b.id = l.bookid
Member table
Books table
lend table
data i need to join
ID membername Bookname issue_date return_date

This is my first post.
It is possible that one of the other tables that you have joined to does not contain the other 2 records. In order to see all records from [lend], you would do this:
SELECT l.id, m.name, b.bookname, l.issuedate, l.returndate FROM lend l LEFT OUTER JOIN member m ON l.memberid = m.id LEFT OUTER JOIN books b ON b.id = l.bookid
I am not sure which table contains the records that you are interested in, but select from only that table first. Check the record count. Then LEFT OUTER JOIN to one more table. Execute. Check record count. Keep going. That way you know which table join has affected the record count.
