Sybase IQ 数据备份

备份可以采用 temp_extract_name1 的语法备份，但是在用定时任务的时候会出现如下的错误

Handler for event 'test_ev' caused SQLSTATE '09W03'

Result set not permitted in 'test_ev'

解决办法

例如：
CREATE PROCEDURE proc1()
BEGIN
SET TEMPORARY OPTION Temp_Extract_Column_Delimiter = '|';
SET TEMPORARY OPTION temp_extract_name1 = 'foo.out';
SELECT * FROM iq_table;
SET TEMPORARY OPTION temp_extract_name1 = '';  
END;
 

CREATE EVENT "test_ev" ENABLE HANDLER
BEGIN
SELECT * INTO #tmp FROM proc1();
END;
TRIGGER EVENT test_ev;
           

动态执行备份语句

if exists(select 1 from sys.sysprocedure where proc_name = 'p_test' and user_name(creator)='bdk') then
   drop procedure bdk.p_test
end if;
create procedure bdk.p_test()
on exception resume
begin
 
declare @sql         varchar(1000);
 
select 1;  --必须加上这句话，不然会报错 试试看呢 

set temporary option Temp_Extract_Column_Delimiter = '|';
set @sql='set temporary option Temp_Extract_Name1 =''/home/backup/abc.bak''';
execute(@sql);
 
set @sql='select * from table01;';
execute(@sql);

set temporary option Temp_Extract_Name1 = '';

end;

bdk.p_test
