# test_compound_select TESTNAME SELECT RESULT
#
#   This command is used to run multiple LIMIT/OFFSET test cases based on 
#   the single SELECT statement passed as the second argument. The SELECT
#   statement may not contain a LIMIT or OFFSET clause. This proc tests
#   many statements of the form:
#    
#     "$SELECT limit $X offset $Y"
#    
#   for various values of $X and $Y.
#    
#   The third argument, $RESULT, should contain the expected result of
#   the command [execsql $SELECT].
#    
#   The first argument, $TESTNAME, is used as the base test case name to
#   pass to [do_test] for each individual LIMIT OFFSET test case.
