sql - Impact: Delete a View, Create table with same name -


so there view in oracle named xyz , says, going replace table of same name.

what kind of impact can create existing sql's written on view? syntax querying view same table?

by "... replace table ..." assume mean table created same data view referencing. in other words, new table redundantly contains data other tables (those view referencing).

select-statements not need changed - syntax same.

but: view reflect changes in underlying tables. table not - have kept in sync triggers or application logic. depending on view, might rather big change. more if view updateable.

example:

suppose view defined ... select a.key, b.name a,b b.key = a.b_ref

then selecting view reflect changes tables a , b.

if replace table, have update new table every time update table a or b.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
