We are on sql server 2008,       but I expect to move to 2012 fairly soon.              SQL Server Native Client 10 is the one we are using, thus        giving me headache.              >But you should not use SELECT * in production code.              Why?              The system is in Ada, and being in Ada it is strongly typed.       That means we use some kind of struct, with members       that corresponds to the fields of a table.       We want to fill the whole struct, because i project adaptions,       they might want to use a field that we do not use in standard.       And then, we find the quality of the system increases a whole lot,       if we get all the data out, instead of just getting the data we want rigth now.       Ie fill all the struct members, or else someone will look at an empty field.       (Yes the y should check this, but experience shows otherwise)                     Besides, the select * are the simple ones, since we have routines that fills       that struct        in correct order.              select a,b,c, from d        are farr worse, since that tends to be              get(a,varA);       get(c,varC);       get(b,varB); <--fail because we got B first.                     This is mostly a problem in migrating old sites,       since the select * method gets it right.              --       Björn Lundin              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
