sql - MySQL query to search a field with JSON string -

-

this might simple enough basic sql or might need regexp i've hit brick wall.

my data stored in json string these 2 examples (each in 1 field):

 [{"id":"2","value":["1","3"]},{"id":"3","value":["1","2"]}]

and:

 [{"id":"3","value":["2"]},{"id":"3","value":["1","2","5"]}]

i want search values in between last brackets might consist of many numbers ["1","2","5"] or single on ["2"]. beginning numbers correspond 2 categories - single "id":"2" , "id":"3".

using %"2"% simple of course matches everything. can query "id":"$var" return each category use php filter through after have results, data can quite large , i'm sure it's easy sql guru.

i don't have option change format of field, has remain json.

any appreciated! thanks.

i think solved using this: and extra_fields regexp '(.*"id":"2".*)("\[.*"1".*\]")'. it's more regular expressions mysql :p

comment: (i couldn't find comment button)
syntax becomes clearer when learn "extra_fields" name of column in table

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
