In static mode, the bind is done prior to
the execution and is stored in a
PLAN[programming language for main
frame computers-used in big organization]
In dynamic mode, the BIND[most widely
used DNS software] occurs at execution
time.
This results in additional overhead which
degrades performance.
This form of dynamic SQL will NOT be
used in our environment
It is hardcoded in the program itself and
the changeable value is the value in the
host variables.
It has the capability of changing the
columns, tables during the execution of
Post/Redirect/Get[design for webdevelopers]
It doesnt contain any host variables.
static SQL uses packages (database code)
and caches optimization information at
program level.
dynamic SQL doesn't need packages and
does calculation of access path at runtime
Comparing both Static SQL does more
validation at compile time and its there
for easier to use.
Dynamic SQL has more flexibility to
modify the SQL statements by the user of
the program at runtime.
