Problem in the output when the table name is explicitly assigned.

Question

hi
Am using a procedure to copy the information's in a table to a flat file. my aim is to achieve this copy function by assigning the table name from user explicitly.
this is the program:
create or replace procedure jk(table_name in varchar2) is
sel_table varchar2(30);
l_bool BOOLEAN;
irows INTEGER := 1;
buffer LONG;
f utl_file.file_type;
BEGIN
sel_table:='select * from '||table_name;
f := utl_file.fopen('SAMPLE','tablename.txt','W');
OWA.cgi_var_name (1) := 1;
OWA.cgi_var_val (1) := 1;
OWA.init_cgi_env (1, OWA.cgi_var_name, OWA.cgi_var_val);
HTP.adddefaulthtmlhdr (FALSE);
l_bool :=
OWA_UTIL.tableprint (ctable => sel_table,
cattributes => '',
ntable_type => OWA_UTIL.pre_table,
ccolumns => '*',
cclauses => '',
ccol_aliases => '',
nrow_min => 0,
nrow_max => 500
WHILE (irows != 0)
LOOP
buffer := HTP.get_line (irows);
utl_file.put_line(f,buffer);
/* do whatever you like with the contents of the buffer */
/* You may write to a file or simply print it out */
DBMS_OUTPUT.put_line (buffer);
END LOOP;
END;
the error during execution:
SQL> @for.sql
Procedure created.
SQL> exec jk('CUST');
BEGIN jk('CUST'); END;
ERROR at line 1:
ORA-00931: missing identifier

You better don't supply the whole select statement to OWA_UTIL.tableprint but only the table name!
