Building a block based on query

Question

Hi,
I've to build a block containing empnumbers from emp table for the emp names entered by the user.
EX: If emp enters SMITH,KING in a text item ,I've to build a mutlirecord block containing emp numbers of these emp names.
I know I've to use EXEC_SQL package to achieve this.
Ex is below:
PROCEDURE getData1 IS
connection_id EXEC_SQL.CONNTYPE;
cursorID EXEC_SQL.CURSTYPE;
sqlstr VARCHAR2(1000);
loc_ename VARCHAR2(30);
loc_eno NUMBER;               
loc_hiredate DATE;
nIgn PLS_INTEGER;
nRows PLS_INTEGER := 0; -- used for counting the actual number of rows returned
i integer:=0;
type l_emp is table of emp%rowtype index by binary_integer;
l_empvar l_emp;
BEGIN
connection_id := EXEC_SQL.OPEN_CONNECTION('scott/tiger@afresrtm');
cursorID := EXEC_SQL.OPEN_CURSOR(connection_id);
sqlstr := 'select empno from emp where ename in :text_item' ;
EXEC_SQL.PARSE(connection_id, cursorID, sqlstr, exec_sql.V7);
--EXEC_SQL.BIND_VARIABLE(connection_id, cursorID, ':bn', input_empno);
EXEC_SQL.DEFINE_COLUMN(connection_id, cursorID, 1, loc_ename, 30);
EXEC_SQL.DEFINE_COLUMN(connection_id, cursorID, 2, loc_eno);     
EXEC_SQL.DEFINE_COLUMN(connection_id, cursorID, 3, loc_hiredate);
nIgn := EXEC_SQL.EXECUTE(connection_id, cursorID);
-- call FETCH_ROWS to obtain a row. When a row is returned, obtain the values,
-- and increment the count.
WHILE (EXEC_SQL.FETCH_ROWS(connection_id, cursorID) > 0 ) LOOP     
nRows := nRows + 1;
EXEC_SQL.COLUMN_VALUE(connection_id, cursorID, 1, loc_ename);
EXEC_SQL.COLUMN_VALUE(connection_id, cursorID, 2, loc_eno);     
EXEC_SQL.COLUMN_VALUE(connection_id, cursorID, 3, loc_hiredate);
l_empvar(i).ename:=loc_ename;
l_empvar(i).empno:=loc_eno;
l_empvar(i).hiredate:=loc_hiredate;
i:=i+1;
END LOOP;
IF (nRows <= 0) THEN
TEXT_IO.PUT_LINE ('Warning: query returned no rows');     
END IF;
for i in 1..l_empvar.last loop
:emp.ename:=l_empvar(i).ename;
:emp.empno:=l_empvar(i).empno;
:emp.hiredate:=l_empvar(i).hiredate;
create_record;
next_record;
end loop;
END;
Here is a pbm in SQL query:
How can I prepare a sql stmt for the input given by user bcoz it has to be varchar.
Pls give me a sol..
Adios..

Hi,
I've not tried this and can't say for sure if it is possible or not.
But, have a look at this link Re: Automatic  Number  of record displayed .
I'd thought of a solution but never tried myself. Try if it works for you.
If it doesn't, i think it will not be possible in oracle forms.
