Identifiers
PQL recognizes an identifier as any sequence of characters that start with a letter, and can include letters, underscores, and numbers. Identifiers are case-insensitive, with some exceptions. Identifiers must start with a letter, and cannot include spaces. You cannot use a reserved word as an identifier, unless you surround it with double quotes, as shown in the following examples.
Example 1: Misuse of reserved word
Query: Find the value of the Index node.
SELECT * FROM /network/device/wmi/win32_networkadaptersetting/element/index
Result: Paglo returns an error message because INDEX
is a reserved word.
ERROR: Syntax error in line 1 at character 35,
didn't expect 'index' here
Example 2: Proper use of reserved word
Query: Find the value of the "Index" node.
SELECT * FROM /network/device/wmi/win32_networkadaptersetting/element/"index\"
Result: The use of double quotes around "index\" changes it from a reserved word into an identifier that produces a result.
row * 1 row * 2 row * 3 . . .
