sql 2 pl/sql
Use native dynamic sql or execute immediate statements .Actually we use these through a built in package of oracle DBMS_SQL.I am writing a sample code 4 u.
create or replace procedure
(p_tab_name in varchar2,p_rows_del out number)
is
cursor_name integer;
begin
cursor_name := dbms_sql.open_cursor;
dbms_sql.parse(cursor_name,'delete from ' || p_tab_name,dbms_sql.native);
p_rows_del:=dbms_sql.execute(cursor_name);
dbms_sql.close_cursor(cursor_name);
end;
/
now u write in SQL*PLUS environment
variable deleted number
execute delete_all_rows('employees',:deleted);
print deleted
i am sending u a oracle documentation link site from where u just download the pdf named "Supplied PLSQL Packages and Types Reference"which will help u surely in these matters.
link is http://zuse.esnig.cifom.ch/database/...v/docindex.htm
