Dynamic insert into variable table statement SQL Server -

-

i have variable table:

declare @a_table table(id int, att1 varchar(100), att2 nvarchar(200))

i want make dynamic sql, insert table data (all inside loop):

while (@i <= 100) begin            select @other_att  = name  @other_table id =  @i;   set @sql = 'insert ' + @a_table+ '(id,att1,att2) select '+cast(@i varchar)+' , '''+ @other_att+''', sum('+ @other_att') '+ @even_other_table; exec (@sql);  end

sql every time like:

insert @a_table select 1 , 'subject', sum(subject) insert @a_table select 2 , 'age', sum(age) insert @a_table select 3 , 'sex', sum(sex)....

and after executing : get:

@a_table: id    att1   att2 1   subject   4.3 2   age       4.5 3   sex       4.1

but error: 

msg 137, level 16, state 1, line 48 must declare scalar variable "@a_table".

so syntax insert dynamically variable table?

ok have understood it.

you have table variable, not variable contains table name.

so need following.

while (@i <= 100) begin            select @other_att  = name  @other_table id =  @i;   set @sql = 'insert @a_table (id,att1,att2) select '+cast(@i varchar)+' , '''+ @other_att+''', sum('+ @other_att') @even_other_table'; exec (@sql);  end

you need declare table variable statement inside @sql variable, , execute declare table , inserts together, or use local/global temporary table.

with local temporary table (stored in tempdb) this. 

create table #testtbl (id int); exec ('insert #testtbl values (1)'); select * #testtbl drop table #testtbl

some info temporary tables in bol

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...
