实习中时常需要将写好的SQL语句嵌入到VB.NET的函数中，例如将下列SQL：

-- Get Mother Lot Common Info
select c.customerlotnumber -- customer lot#
,c.containername --Amkor lot#,
,amk.description
,inh.txndate indate--s_time
,outh.txndate outdate -- e-time
,rs.resourcename resourcename
,emp.fullname
-- ,outh.qty
from container c,historymainline hml,workflowstep wfs
,operation opt,movehistory outh,moveinhistory inh
,RESOURCEDEF rs
,amkorwwoper amk
,employee emp
where c.splitfromid =(select containerid from container where
containername='ML6410058461')
and hml.reversalstatus=1
and c.containerid=hml.containerid
and hml.operationid=opt.operationid
and hml.workflowstepid=wfs.workflowstepid
and hml.operationid=opt.operationid
and hml.historymainlineid=inh.historymainlineid(+)
and hml.historymainlineid=outh.historymainlineid(+)
and HMl.RESOURCEID=RS.RESOURCEID(+)
and (outh.historymainlineid is not null or inh.historymainlineid is not null)
and opt.amkorwwoperid=amk.amkorwwoperid
and hml.employeeid=emp.employeeid
order by c.containername,to_number(wfs.sequence),inh.txndate,outh.txndate
转换如下形式为：
String sql in VB.NET
sql = "select c.customerlotnumber -- customer lot# " & vbCrLf _
& ",c.containername --Amkor lot#, " & vbCrLf _
& ",amk.description " & vbCrLf _
& ",inh.txndate indate--s_time " & vbCrLf _
& ",outh.txndate outdate -- e-time " & vbCrLf _
& ",rs.resourcename resourcename " & vbCrLf _
& ",emp.fullname " & vbCrLf _
& "-- ,outh.qty " & vbCrLf _
& "from container c,historymainline hml,workflowstep wfs " & vbCrLf _
& ",operation opt,movehistory outh,moveinhistory inh " & vbCrLf _
& ",RESOURCEDEF rs " & vbCrLf _
& ",amkorwwoper amk " & vbCrLf _
& ",employee emp " & vbCrLf _
& "where c.splitfromid =(select containerid from container where " & vbCrLf _
& "containername='ML6410058461') " & vbCrLf _
& "and hml.reversalstatus=1 " '..

同事Tracy告诉我一个快速方法，仅仅利用UltraEdit的查找替换功能（<>号不填，仅为引用号），
查找：< ^p >
替换：< " & vbCrLf _ ^p & " >
替换的第一个"号前不可省去空格，然后填上头尾即可，^p代表回车符，也就是将回车符展开，是不是很有趣的技巧？
