sql server - Creating a table using dynamic sql -


i want use dynamic sql within stored procedure create table.

here call stored procedure:

exec [spcreateacoldifftable] 'hq193.dbo.arch_con_col_s193_s202'

here relevant parts of stored procedure:

create procedure sp_createacoldifftable (@table_name nvarchar(128))

...

set @ssql = 'create table ' + @table_name + ' ( ' + ' [table_name]       varchar (128) not null, ' + ' [column_name]      varchar (128) null, ' + ' [what_changed]     varchar (128) null, ' + ' [sr_data_type]     varchar (128) not null, ' + ' [tr_data_type]     varchar (128) not null, ' + ' [sr_max_length]    smallint not null, ' + ' [tr_max_length]    smallint not null, ' + ' [sr_is_nullable]   char null, ' + ' [tr_is_nullable]   char null, ' + ' [sr_precision]     smallint null, ' + ' [tr_precision]     smallint null, ' + ' [sr_scale]         smallint null, ' + ' [tr_scale]         smallint null ) ' + ' on [primary] (data_compression = none)' print @ssql exec @ssql

go

when run stored procedure receive error:

sql server database error: name 'create table hq193.dbo.arch_con_col_s193_s202 ( [table_name] varchar (128) not null, [column_name] varchar (128) null, [what_changed] varchar (128) null, [sr_data_type] varchar (128) not null, [tr_data_type] varchar (128) not null, [sr_max_length] smallint not null, [tr_max_length] smallint not null, [sr_is_nullable] char null, [tr_is_nullable] char null, [sr_precision] smallint null, [tr_precision] smallint null, [sr_scale] smallint null, [tr_scale] smallint null ) on [primary] (data_compression = none)'

is not valid identifier.

notice in stored procedure printed out sql before executed it. if cut , paste sql gets printed query editor window works fine.

what missing?

try this:

exec(@ssql)

this common error. without parenthesis, exec @ssql means "execute stored procedure name in @ssql variable", rather want "execute command string in variable @ssql."

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...

i'm learning java , have question regarding reading file want read numbers file contains strings well. here example of file: 66.56 "3 java 3-43 5-42 2.1 1 and here coding: public class test { public static void main (string [] args){ if (0 < args.length) { file x = new file(args[0]); try{ scanner in = new scanner( new fileinputstream(x)); arraylist<double> test = new arraylist<>(); while(in.hasnext()){ if(in.hasnextdouble()){ double f=in.nextdouble(); test.add(f);} else {in.next();} } catch(ioexception e) { system.err.println("exception during reading: " + e); } } my problem add 66.56,2.1 , 1 doesn't add 3 after "3 or ignores 3-43 , 5-42 can tell me how skip strings , add doubles here? thanks all said 3 ie; "3, 3-43 , 4-42 strings either u read string , split , check number @ " , - or put in space between characters , integers. jvm after compilation tre...
