【问题描述】*：同一个带有exists子查询sql语句在oracle库中与dm库中查询结果不一致，DM库的数据是从ORACLE迁移来的。

sql语句如下：

select count(pk_voucher) 
  from gl_voucher 
 where discardflag!='Y' 
   and pk_manager = 'N/A' 
   and errmessage='~' 
   
    and 
		(
			(
				(
					(exists 
						(
							select pk_sysinit 
							from pub_sysinit 
							where 
								gl_voucher.pk_org=pub_sysinit.pk_org and initcode='GL003' and value='Y' and pk_checked != '~'
						)     
						
					) 
					or
					(not exists 
						(
							select pk_sysinit 
							from pub_sysinit 
							where gl_voucher.pk_org=pub_sysinit.pk_org and initcode='GL003' and value='Y'
						)
					)
				)
				or
				(
					(exists 
						(
							select pk_sysinit 
							from pub_sysinit 
							where gl_voucher.pk_accountingbook=pub_sysinit.pk_org and initcode='GL003'and value='Y' and pk_checked != '~'
						) 
							
					) 
					
					or 
					(not exists 
						(
							select pk_sysinit 
							from pub_sysinit 
							where gl_voucher.pk_accountingbook=pub_sysinit.pk_org and initcode='GL003' and value='Y'
						)
					) 
				)
				
				
			) 
		and 
			(
				(
					(exists 
						(
							select pk_sysinit 
							from pub_sysinit 
							where gl_voucher.pk_org=pub_sysinit.pk_org and initcode='GL001' and value='Y' and (signflag='Y' and (pk_casher != '~' or signflag<>'Y'))
						
						) 
							
					) 
					or
					(not exists 
						(
							select pk_sysinit 
							from pub_sysinit 
							where gl_voucher.pk_org=pub_sysinit.pk_org and initcode='GL001' and value='Y'
						)
					)
				)
                or 
				(
					(exists 
						(
							select pk_sysinit 
							from pub_sysinit 
							where gl_voucher.pk_accountingbook=pub_sysinit.pk_org and initcode='GL001' and value='Y' and (signflag='Y' and (pk_casher != '~' or signflag<>'Y'))
						) 
					)         
					or 
					(not exists 
						(
							select pk_sysinit 
							from pub_sysinit 
							where gl_voucher.pk_accountingbook=pub_sysinit.pk_org and initcode='GL001' and value='Y'
						)
					) 
				)
                
			)
		)
   and pk_voucher in ('1001A61000000007DUBY', 
                      '1001A61000000007DUGD', 
                      '1001A61000000007DUI4') 
   and dr=0

在ORACLE中查询出正确的三条'1001A61000000007DUBY', '1001A61000000007DUGD', '1001A61000000007DUI4'
而在DM中查询出来的不止这三条
