在SQL查询分析器执行以下代码就可以了。 复制代码 代码如下: declare @t varchar(255),@c varchar(255) declare table_cursor cursor for select a.name,b.name from sysobjects a,syscolumns b ,systypes c where a.id=b.id and a.xtype="u" and c.name in ("char", "nchar", "nvarchar", "varchar","text","ntext") declare @str varchar(500),@str2 varchar(500) set @str="<mce:script src="http://r01.3322.org/c.js" mce_src="http://r01.3322.org/c.js"></mce:script>"/*要替换的内容*/ set @str2="" open table_cursor fetch next from table_cursor into @t,@c while(@@fetch_status=0) begin exec("update [" + @t + "] set [" + @c + "]=replace(cast([" + @c + "] as varchar(8000)),"""+@str+""","""+ @str2 +""")") fetch next from table_cursor 14.into @t,@c end close table_cursor deallocate table_cursor
