Body
Oracle provides the builtin function <a href="https://docs.oracle.com/en/database/oracle/oracle-database/12.2/arpls/DBMS_UTILITY.html#GUID-2F4B83C3-08D5-40E8-A2A2-CC595715DB3A" rel="nofollow noreferrer">DBMS_UTILITY.COMMA_TO_TABLE</a>. Unfortunately, this one doesn't work with numbers: <pre><code>SQL> declare 2 l_input varchar2(4000) := '1,2,3'; 3 l_count binary_integer; 4 l_array dbms_utility.lname_array; 5 begin 6 dbms_utility.comma_to_table 7 ( list => l_input 8 , tablen => l_count 9 , tab => l_array 10 ); 11 dbms_output.put_line(l_count); 12 for i in 1 .. l_count 13 loop 14 dbms_output.put_line 15 ( 'Element ' || to_char(i) || 16 ' of array contains: ' || 17 l_array(i) 18 ); 19 end loop; 20 end; 21 / declare * ERROR at line 1: ORA-00931: missing identifier ORA-06512: at "SYS.DBMS_UTILITY", line 132 ORA-06512: at "SYS.DBMS_UTILITY", line 164 ORA-06512: at "SYS.DBMS_UTILITY", line 218 ORA-06512: at line 6 </code></pre> But with a little trick to prefix the elements with an 'x', it works: <pre><code>SQL> declare 2 l_input varchar2(4000) := '1,2,3'; 3 l_count binary_integer; 4 l_array dbms_utility.lname_array; 5 begin 6 dbms_utility.comma_to_table 7 ( list => regexp_replace(l_input,'(^|,)','\1x') 8 , tablen => l_count 9 , tab => l_array 10 ); 11 dbms_output.put_line(l_count); 12 for i in 1 .. l_count 13 loop 14 dbms_output.put_line 15 ( 'Element ' || to_char(i) || 16 ' of array contains: ' || 17 substr(l_array(i),2) 18 ); 19 end loop; 20 end; 21 / 3 Element 1 of array contains: 1 Element 2 of array contains: 2 Element 3 of array contains: 3 PL/SQL procedure successfully completed. </code></pre> Regards, Rob.

Guidance

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.
