Can we exclude some field while we do the query like select * from
basically what i need is like this…
select * from tabl ( exclude id field which is primary and AI ) where id=5;
is it possible in mysql?
how to create a query to select all columns except AI column, without quoting all column names in query.
The only way of doing it is by specifying all of the columns by name apart from the one you want to select.
If you do use select *, you can then just ignore the column you don’t want when you process the data.
You shouldn’t really use select * in your code at all as that will mean that the code needs rewriting if you ever need to change the fields in the table. You really ought to list the fields you actually need so that the code will not be affected by adding or deleting any of the other fields in the table that this particular call doesn’t need to reference.
not very good advice
what if the column not needed is a BLOB?
Please explain little more with sql, how can we use ignore on particular cases though some restrictions are there as posted by r937

Answer is already given in post #4 by felgall
there is no “ignore” in sql
if you want all columns of a table except one, you must list the columns you want
in other words, this –
