what is preceeding load
The bold part is the preceding load in this simple example:
LOAD A, B, C;
SQL SELECT
A,B,C FROM Table;

thank u
It is the LOAD statement you add ABOVE the SQL load statement, that will allow you to use internal QlikView functions, to be able to transform your data.
besides the above valuable comments
its also mskes the code easier to read eg
without preceding load
load subfield(just imagine this is a very long formular) as firstname ,
another very long formular as surname,
very long formular & another very long form as fullname
with preciding load
an easier way is just type
load * ,
firstname & surname as fullname ;
load subfield(just imagaine this is very long ...) as firstname,
...... as surname
from (...) ;
