    <p>You could pass in an Oracle collection type as a parameter.</p> <p>The collection could be a key value pair such as an associative array indexed by a varchar. In that example, the index could be the SID and the value could be the SNAME.</p> <p>Read here to learn about collections: <a href="http://docs.oracle.com/cd/B10501_01/appdev.920/a96624/05_colls.htm" rel="nofollow">http://docs.oracle.com/cd/B10501_01/appdev.920/a96624/05_colls.htm</a></p> <p>And here for associative arrays in particular: <a href="http://www.oracle-base.com/articles/9i/AssociativeArrays9i.php" rel="nofollow">http://www.oracle-base.com/articles/9i/AssociativeArrays9i.php</a></p> <p>Alternatively you could pass two parameters, both collections holding varchar values (such as DBMS_SQL.VARCHAR2_TABLE types) the first holding the SID and the second holding the corresponding SNAME values they would effectively be linked by their index number. See here for DBMS_SQL defined types: <a href="http://docs.oracle.com/cd/B19306_01/appdev.102/b14258/d_sql.htm" rel="nofollow">http://docs.oracle.com/cd/B19306_01/appdev.102/b14258/d_sql.htm</a></p> <p>Hope it helps...</p> <p>EDIT:</p> <p>If you are declaring all types and performing all actions within a package then:</p> <pre><code>-- Declare type TYPE student_coltype IS TABLE OF student%ROWTYPE INDEX BY BINARY_INTEGER; -- Declare variable of type student_col student_coltype; </code></pre> <p>If you want global types then you'll have to explicitly declare the columns:</p> <pre><code>CREATE TYPE student_rec AS OBJECT (SID VARCHAR2(10), SNAME VARCHAR2(50)); CREATE TYPE student_collection AS TABLE OF student_rec; </code></pre> <p>You can then use the student collection type with your DB to pass collections of student data into and out of procedures and functions.</p> <p>The docs for using oracle objects are here: <a href="http://docs.oracle.com/cd/B19306_01/appdev.102/b14260/adobjint.htm" rel="nofollow">http://docs.oracle.com/cd/B19306_01/appdev.102/b14260/adobjint.htm</a></p>

    1. COBut the table may expand horizontally in future, I need something that is logically equivalent to List<Students> in Java.

    2. COIf you mean there could be more columns in the table, then you could still use an Oracle collection. The collection would be a collection of records. Define your record based upon the STUDENTS table %ROWTYPE and it will dynamically change as your table does.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
