我正在尝试使用以下代码创建和分配变量，以便在plsql（11g）中创建对象类型但面临一些错误：
begin
execute immediate 'drop type picu_obj force';
execute immediate 'drop type picu_obj_tab force';
execute immediate 'create type picu_obj as object(Customer_ID varchar2(32767),Customer_Name varchar2(32767),Server_Name varchar2(32767),Time_stamp varchar2(32767))';
execute immediate 'create type picu_obj_tab is table of picu_obj;';
picu_var picu_obj_tab;
picu_var := picu_obj_tab(picu_obj('101','xyz','pro-ssr-qr','12:13'));
end;
The above code gives following errors:
ERROR at line 6:
ORA-06550: line 6, column 10:
PLS-00103: Encountered the symbol "PICU_OBJ_TAB" when expecting one of the
following:
:= . ( @ % ;
The symbol ":=" was substituted for "PICU_OBJ_TAB" to continue.
请在这里建议我做错了什么。
