sql server 2005 - IF, RAISERROR & RETURN in Stored Procedure -


i have stored procedure, proc, receives parameters. if 1 of them, @id, not null, given stored procedure, proc_a, must executed. otherwise, proc_b must executed. problem both of them may issue raiserror, want propagate through call stack displayed @ client application. however, raiserror won't stop rest of proc stored procedure should, and, since using if clause, checking if ( @@error <> 0 ) return isn't option either. choice seems using try...catch block wrap if clause , rethrow raiserror within catch block, awkwards because have cache error_message(), error_severity() , error_state() , use raiserror once again.

isn't there more elegant way?

just use try - catch block , echo original error, isn't hard do:

begin try     --used in catch block echo error     declare @errormessage nvarchar(400), @errornumber int, @errorseverity int, @errorstate int, @errorline int      --your stuff here  end try begin catch      --your error code/logging here      --will echo complete original error message     select @errormessage = n'error %d, line %d, message: '+error_message(),@errornumber = error_number(),@errorseverity = error_severity(),@errorstate = error_state(),@errorline = error_line()     raiserror (@errormessage, @errorseverity, @errorstate, @errornumber,@errorline)  end catch

also, best practice have entire procedure in try - catch, , not external procedure calls.

for class project i'm attempting write vst plugin backed cuda. current cuda workflow on linux box, i'd prefer compile , link there. according wikipedia , should possible (i couldn't find steinberg documentation relevant linux) can't find makefile or instructions on how build if aren't using xcode or visual studio. i'm vst 3 sdk doesn't support linux. when try compile plugin under linux, error: ./base/source/fatomic.cpp:39:30: fatal error: libkern/osatomic.h: no such file or directory this issue caused following code in "vst3 sdk/base/source/fatomic.cpp" #if mac #include <libkern/osatomic.h> #if mac_os_x_version_min_required > mac_os_x_version_10_4 #define native_atomic_type (volatile int32_t*) #else #define native_atomic_type (int32_t*) #endif #elif windows #include <windows.h> #endif but hope compiling under linux work vst sdk 2.4. reading. jvstwrapper seems run on lin...
