oracle - 执行存储过程时出错

Question

在执行以下存储过程时，我在 Oracle 中遇到错误。您能否让我知道错误是什么。

[Error] Syntax check (5: 22): ERROR line 5, col 22, ending_line 5, ending_col 22, Found 'TABLE', Expecting: ;   -or-   :=   -or-   .   -or-   @   -or-   (  ROW

PROCEDURE MyProcedure(res OUT NUMBER)
 AS
      is_output    BOOLEAN;
BEGIN
 TRUNCATE TABLE MyTable;

END MyProcedure;

Answer 1

TRUNCATEEXECUTE IMMEDIATE是一个DDL语句，所以从pl/sql调用时需要使用..

PROCEDURE MyProcedure(res OUT NUMBER)
AS
    is_output    BOOLEAN;
BEGIN

    EXECUTE IMMEDIATE 'TRUNCATE TABLE MyTable';

END MyProcedure;
