SQL Server: drop a FK constraint, which is not foreign key -


i using sql server 2008 , management studio. doing web project, has tool automate tables/relationships creation.

my web project reveals error:

unsuccessful: alter table tester add constraint fk_c6c4bf4s2rvp56a32nnruww2b foreign key (game) references game

column 'game.id' not same data type referencing column 'tester.game' in foreign key 'fk_c6c4bf4s2rvp56a32nnruww2b'

however, when ran following in management studio:

alter table dbo.tester drop constraint fk_c6c4bf4s2rvp56a32nnruww2b

i following:

msg 3728, level 16, state 1, line 1
'fk_c6c4bf4s2rvp56a32nnruww2b' not constraint.
msg 3727, level 16, state 0, line 1
not drop constraint. see previous errors.

i confused. type of constraint fk_c6c4bf4s2rvp56a32nnruww2b?

how can remove it?

thanks , regards.

there no such constraint!

the first error says could not create constraint since datatypes of 2 columns involved (game.id , tester.game) not match.

what should check how you're creating fk constraint leads first error - , explicitly give fk constraint meaningful name!

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!
