ROWTYPE definition in pl/sql - plsql

Question

I have written a PL/SQL Procedure which compares data between two tables and print the difference if any, but the twist is the table names to the procedure is dynamic. Here is the procedure
create or replace PROCEDURE compareTables(
tabA IN VARCHAR2, tabB IN VARCHAR2) AS
cur_tab_name USER_TABLES%ROWTYPE;
lv_sql varchar2(4000);
lv_sql2 varchar2(4000);
BEGIN
--SELECT TABLE_NAME INTO cur_tab_name FROM USER_TABLES WHERE TABLE_NAME = tabA;
lv_sql2 := 'SELECT TABLE_NAME FROM USER_TABLES WHERE TABLE_NAME = :b_tabA';
EXECUTE IMMEDIATE lv_sql2 INTO cur_tab_name USING tabA;
<<child>>
DECLARE
TYPE cursor_ref IS REF CURSOR;
cur_comp_result cursor_ref;
rec_comp_result cur_tab_name.TABLE_NAME%rowtype;
BEGIN
lv_sql := 'SELECT * FROM '||tabA||' MINUS SELECT * FROM '||tabB;
OPEN cur_comp_result FOR lv_sql;
LOOP
FETCH cur_comp_result INTO rec_comp_result;
EXIT WHEN cur_comp_result%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(rec_comp_result.empid || '' || rec_comp_result.name);
END LOOP;
CLOSE cur_comp_result;
Exception
When others then
dbms_output.put_line('The Problem is '||sqlerrm);
END;
END compareTables;
Now the problem is when I compile this procedure I am getting the following error
Error at line 14: PLS-00310: with %ROWTYPE attribute, 'CUR_TAB_NAME.TABLE_NAME' must name a table, cursor or cursor-variable
line 14:rec_comp_result cur_tab_name.TABLE_NAME%rowtype;
how will I solve it?
*NB: I don't have oracle installed in my system. I am using Oracle Apex Online tool which uses
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 and
PL/SQL Release 11.2.0.3.0

Answer 1

As a test, go to the last line, and after the semicolon, hit enter.
I know that Pro*C in particular will gag without a line terminator at the end of the file.
You may be encounting that issue.
Outside the scope of your question consider
SELECT columns
FROM TABLE1
MINUS
SELECT columns
FROM TABLE2
and
SELECT columns
FROM TABLE2
MINUS
SELECT columns
FROM TABLE1

Answer 2

Use: cur_tab_name.table_name. The variable CUR_TAB_NAMEis of type USER_TABLE%ROWTYPE, thus it has several fields.
