ddl in PL/SQL

If you write DDL directly in PL/SQL. You will hit error.

  1  DECLARE
  2     str_sql varchar2(500);
  3  begin
  4     create table test (id number);
  5  end;
  6  /
        create table test (id number);
        *
ERROR at line 4:
ORA-06550: line 4, column 2:
PLS-00103: Encountered the symbol "CREATE" when expecting one of the following:
begin case declare exit for goto if loop mod null pragma
raise return select update while with <an identifier>
<a double-quoted delimited-identifier> <a bind variable> <<
close current delete fetch lock insert open rollback
savepoint set sql execute commit forall merge pipe

　　

But you can use dynamic run as below.

  1  DECLARE
  2    str_sql varchar2(500);
  3  begin
  4    str_sql := 'create table test (id number)';
  5    execute immediate str_sql;
  6  end
  7      ;
  8   /
