IntegerValue

'CharacterString'
0xHexadecimalString
}
- IntegerValue
is a signed or unsigned whole number compatible with INTEGER or
SMALLINT data types, for example:
-16746
155
5
- FloatValue
is a signed or unsigned floating point number compatible with the
FLOAT or REAL data types, for example:
.2E-4
- FixedPointValue
is a signed or unsigned fixed-point number compatible with the DECIMAL
data type, for example:
-15.99
+1451.1
- CharacterString
is a character string compatible with CHAR, VARCHAR, DATE, TIME,
DATETIME, or INTERVAL data types. String constants are delimited by
single quotation marks, for example:
'DON''T JUMP!'
However, two single quotation marks in a row are interpreted as a single
quotation mark, not as string delimiters.
- HexadecimalString
is a string of hexadecimal digits 0 through 9 and A through F (the
lowercase a through f are also accepted) compatible with the BINARY and
VARBINARY data types. A HexadecimalString constant must
be prefaced with the characters 0x, for example:
0xFFFAB0880088343330FFAA7
0x000V001231
