MySQL to read relational algebra? -


i'm trying mysql take relational algebra input not accept projections , forth symbols.

for example 

Πstarter, ender, pointsstarter, pointsender, debatedate (contest)

i errors projection not accepted.

i have 

(Πstarter, ender, pointsstarter, pointsender, debatedate(σpointsstarter>=pointsender(contest))) |>

contest.starter=debater.name (σclub=’plato’(debater))

mysql not accept it, thoughts?

valid mysql input in form of sql queries, not relational algebra expressions. although, if did, quite interesting.

edit: ra piece of java software converts relational algebra sql queries, if you'd go down path.

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!
