+What about PL/SQL? The calls are nearly the same - the only difference is the creation of the cursor since the cursor() function is a SQL-only function. The first example in PL/SQL would look like this:
+
+~~~
+declare
+  l_cursor sys_refcursor;
+  l_clob  clob;
+begin
+  open l_cursor for select * from emp e;
+  l_clob := cursor2lob.to_clob(
+         l_cursor, /* Cursor */
+         chr(10),  /* Row Separator */
+         ';',      /* Column Separator */
+         '"',      /* Delimiter */
+         1         /* 1 -> First row includes column names */
+       );
+end;
+~~~

 Cursor2LOB fetches the data as VARCHAR2s or as CLOBs. If a column type is not of these two then an implicit conversion to VARCHAR2 is attempted using the default NLS and format mask settings of your session. If you want to get a specific format for your NUMBERs or DATEs etc. then you'll have to use the TO_CHAR function and provide a format mask.

If you want to get a specific format for your NUMBERs or DATEs etc. then you'll have to use the TO_CHAR function and provide a format mask.

 It's not possible to fetch object types, nested tables or BLOBs as such because there is no reasonable implicit conversion of these types to a VARCHAR2. If you want to get those into your LOB, you'll have to convert them yourself to a VARCHAR2 or CLOB explicitly.

+Generating the same data as a fixed-column format works this way:
+
+~~~
+select d.deptno, d.dname,

+                       rpad(e.sal, 8, ' ')
+                from   emp e
+                where  e.deptno = d.deptno), /* Cursor */
+         chr(10),                     /* Row Separator */
+         null                         /* Column Separator */
