phpmyadmin - Why won't MySQL let me remove attribute "on update CURRENT_TIMESTAMP"? -

-

i have table 2 timestamp fields. defined them name , type timestamp, yet reason mysql automatically set 1 of them default value , attribute on update current_timestamp. planning on having no default value in either of fields, 1 of fields called "date_updated" suppose set mentioned attribute field.

unfortunately, it's field "date_created" set on update current_timestamp attribute, , no matter do, mysql won't let me remove it.

i've tried editing "date_created" field , removing attribute. when clicking save, attribute back. have tried selecting both fields, removing attribute 1 of them , setting on other. gives me error #1293 - incorrect table definition; there can 1 timestamp column current_timestamp in default or on update clause , both attribute columns on values set on update current_timestamp result:

error sql query:  alter table  `pages` change  `date_created`  `date_created` timestamp not null , change  `date_updated`  `date_updated` timestamp on update current_timestamp not null  mysql said:   #1293 - incorrect table definition; there can 1 timestamp column current_timestamp in default or on update clause

must recreate both columns in correct order fix this?

i know how solve problem correctly, future reference.

thanks

now i've tried run

alter table pages change date_created  date_created timestamp not null

you should specify default current_timestamp (or default 0)

alter table pages change date_created date_created timestamp not null default 0, change  `date_updated`  `date_updated` timestamp on update current_timestamp not null

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...
