Description of the differences between the MIN function and the MAX function and differences between the SELECT-SQL MIN field function and the MAX field function in FoxPro

This article was previously published under Q98362
SUMMARY
There are distinct differences between the MIN() and MAX() functions andthe SELECT-SQL MIN() and MAX() field functions. The SELECT-SQL MIN() andMAX() field functions accept only one argument, whereas the MIN() and MAX()functions accept multiple arguments.

The following examples demonstrate how each function would be used in aFoxPro program.
SELECT MIN(price) from detail     && This statement will select the record with lowest price     && in the database.   SELECT MIN(IIF(price < 0,0,price)) FROM detail     && This statement will select the record with the lowest price     && as long as it is not less than zero; if it is less than zero,     && it will return zero (0).   ?MIN(54, 39, 40)     && This statement will return the minimum of the three parameters     && (39).   ?MAX(54, 39, 40)     && This statement will return the maximum of the three parameters     && (54).   SELECT MIN(price,0) from detail     && This statement will cause the error " MISSING ) " to occur.     && To correct this statement, remove the second argument from     && the MIN() function, as shown in the first example.		
For Visual FoxPro 6.0 and later versions, use this code:
open database home(2)+"data\testdata.dbc"SELECT MIN(order_amt) from orders     && This statement will select the record with lowest price     && in the database.   SELECT MIN(IIF(order_amt < 0,0,order_amt)) FROM orders     && This statement will select the record with the lowest price     && as long as it is not less than zero; if it is less than zero,     && it will return zero (0).   ?MIN(54, 39, 40)     && This statement will return the minimum of the three parameters     && (39).   ?MAX(54, 39, 40)     && This statement will return the maximum of the three parameters     && (54).   SELECT MIN(order_amt,0) from orders     && This statement will cause the error " MISSING ) " to occur.     && To correct this statement, remove the second argument from     && the MIN() function, as shown in the first example.
