Dynamic report issue

Question

Dears, I'm back again
I have and issue with my dynamic report:
My source:
DECLARE
vTABLE VARCHAR2(100);
vCOLUMN VARCHAR2(100);
vVALUE varchar2(100);
vSQL VARCHAR2(1000);
BEGIN
vTABLE := :P46_TABLELIST;
vCOLUMN:=:P46_COLUMNLIST;
vVALUE:=:P46_COLVALUE;
     vSQL := 'SELECT '||vCOLUMN || ' FROM ' || vTABLE || 'WHERE '|| vCOLUMN ||'='||vVALUE||;
RETURN vSQL;
END;
And it doesn't work fine.
When I run it in SQL workshop i have this error :
ORA-06550: line 11, column 88:
PLS-00103: Encountered the symbol ";" when expecting one of the following:
( - + case mod new null
avg
count current max min prior sql stddev sum variance execute
forall merge time timestamp interval date
pipe
1. DECLARE
2. vTABLE VARCHAR2(100);
3. vCOLUMN VARCHAR2(100);

Answer 1

Celio, first you have to build function on database
CREATE OR REPLACE FUNCTION your_function
RETURN VARCHAR2
IS
vSQL varchar2(4000);
BEGIN
vSQL := 'SELECT '||v('P46_COLUMNLIST') || ' FROM ' ||v('P46_TABLELIST') || ' WHERE '||v('P46_COLUMNLIST') ||'='||v('P46_COLVALUE');
RETURN vSQL;
end;
Second
You have to run function in SQL region
RETURN your_function;
And last
You have to check "Use Generic Column Names (parse query at runtime only)" radio and set number of column for example 1.
