Literals for 5800 System DataTypes
For each 5800 system data type, there is a syntax to include literals of that type in a query string.
The syntax is {type_name ’stringliteral’}. For example, consider the query:
timestamp_field<{timestamp ’2006-10-26T12:00:00Z’}
In particular, this syntax can be used to query for a particular object ID:
system.object_id = {objectid
’0200011e61c159bdfa654e11db8a45cafecafecafe000000000200000000’}
For comparing against binary values, either of the following forms may be used:
binary_field = x’beeffeed’
binary_field = {binary ’beeffeed’}
For more information, see
“Canonical String Format” on page 119.
Canonical String Format
Each type in a 5800 system has a canonical representation as a string value. The canonical
string representation of each type is shown in
Table 4–1.
TABLE 4–1 Canonical String Representation of Data Types
DataType Canonical String Representation
STRING The string itself.
CHAR The string itself.
BINARY Hexadecimal dump of the value with two hex digits per byte.
LONG Result of Long.toString. For example, 88991 or -7975432785.
DOUBLE Result of Double.toString. For example, 1.45 or NaN or -Infinity or -1.56E200.
DATE YYYY-mm-dd. For example, 2001-01-01.
TIME HH:mm:sss. For example, 12:02:01.
TIMESTAMP YYYY-mm-ddThh:mm:ss.fffZ (time relative to UTC). For example,
1969-12-31T23:59:59.999Z.
OBJECTID 60-digit hexadecimal dump of the objectid.
This canonical string encoding is used in the following places:
