the type Text, Number or Date/Time. The result type is always a num-
ber (1 = true, 0 = false).

"Metrohm" > "AG" --> 1

"Aarau" > "Zug" --> 0

When making a comparison between two
texts the ASCII value of the character
sequence is compared (see Chapter
2.4.4.10, page 89)
. Attention: Upper-
case and lowercase letters have different
values!

Number

Time(1998;04;06) >

Operands of a different type:

Number

1.2 > "Metrohm" --> 01.23 >
"1.2" --> 1

Before the relational operation, the Num-
ber
is converted to Text, afterwards the
texts are compared according to ASCII
value
(see Chapter 2.4.4.10, page 89).

Before the operation, the operand is con-
verted from the type Date/Time to Text
(here thus: "1999-10-07 00:00:00 UTC
+2"
), afterwards the texts are compared
according to ASCII value (see Chapter
2.4.4.10, page 89)
.
