我对编程有点陌生,因此不胜感激。
在我的存储过程的代码下面找到删除一个表并创建一个每小时运行的 DBA 作业。
CREATE OR REPLACE procedure DELETE_My_TABLE(myschema varchar2) as
BEGIN
BEGIN
execute immediate 'delete from '||myschema||'.mytable where clause;';
END;
BEGIN
DBMS_SCHEDULER.create_program (
program_name => 'DELETE_My_TABLE',
program_type => 'STORED_PROCEDURE',
program_action => 'execute DELETE_My_TABLE(myschema)',
number_of_arguments => 1,
enabled => FALSE,
comments => 'Program to delete table using a stored procedure.');
DBMS_SCHEDULER.define_program_argument (
program_name => 'DELETE_My_TABLE',
argument_name => 'myschema',
argument_position => 1,
argument_type => 'VARCHAR2',
default_value => 'myschema');
DBMS_SCHEDULER.enable (name => 'DELETE_My_TABLE');
END;
BEGIN
DBMS_SCHEDULER.create_schedule (
schedule_name => 'DELETE_My_TABLE',
start_date => SYSTIMESTAMP,
repeat_interval => 'freq=hourly; byminute=0',
end_date => NULL,
comments => 'Hourly Job to purge SEARCH_TEMP_TABLE');
END;
END;
/
问题:
ERROR at line 1:
ORA-00920: invalid relational operator
ORA-06512: at "MYSCHEMA.DELETE_My_TABLE", line 4
ORA-06512: at line 1
逻辑(和语法)会起作用吗?
