我的參數(shù)沒亂碼，sql卻成了select ID,COMMAND,DESCRIPTION,CONTENT from message where 1=1 and COMMAND = ? ? select ID,COMMAND,DESCRIPTION,CONTENT from message where 1=1 and DESCRIPTION like '%' ? '%' 參數(shù)就沒替換上去，這是為什么?那位大神能幫我解決一下

select ID,COMMAND,DESCRIPTION,CONTENT from message where 1=1 and DESCRIPTION like ？

select ID,COMMAND,DESCRIPTION,CONTENT from message where 1=1 and COMMAND = ?這句話沒錯
select ID,COMMAND,DESCRIPTION,CONTENT from message where 1=1 and DESCRIPTION like '% {$description} %'?
