请教下db2 存储过程 变量声明位置

当我把变量declare在其他ddl语句之后，在导入存储过程的时候，就出现："后面找到异常标记"END-OF-STATEMENT"。预期标记可能包括：""
如果放在前面就没问题
问下db2的变量声明必须这样么，因为我有嵌套的declare continue handler for data not found使用

是的，你必须在第一次使用前声明并且赋值，否则就会报错，很多语言都是这样的，你在一段java代码中一样要在使用前声明切初始化的。

把所有变量声明都放在开头，如： create procedure "aml"."czjy053" (in "datadate" varchar(8) ) begin declare period varchar(20);--回顾周期 declare times varchar(20);--周期内发生次数 declare sum_crat varchar(20);--周期内金额总额 set period = (select value from context_variable where type = 'czjy053' and key = 'period'); set times = (select value from context_variable where type = 'czjy053' and key = 'times'); set sum_crat = (select value from context_variable where type = 'czjy053' and key = 'sum_crat'); delete from t_fxqnbs where remark1 = 'czjy053'; insert into t_fxqnbs select * from fxqtrade_cc trans,(select csnm,tcac from fxqtrade_cc where tstm>to_char(to_date(datadate,'yyyymmdd')-period days,'yyyymmdd') and opcustomtype in (select key_value from fxqparam where key ='opcustomtype_cc') group by csnm,tcac having count(*)>=9 and sum(crat) >=1800000) a where trans.tstm = datadate and trans.csnm = a.csnm and trans.tcac = a.tcac; end;
