SWbemRpnEncodedQuery structure (wmiutils.h)
The SWbemRpnEncodedQuery structure contains information from the IWbemQuery::GetAnalysis method when you use the WMIQ_ANALYSIS_RPN_SEQUENCE analysis type. Not all the fields in the structure are used actively, because some are reserved for future use.

Members
m_uVersion
Unused. Value is always 1.
m_uTokenType
Unused. Value is always 0 (zero).
m_uParsedFeatureMask
Unused. Value is always 0 (zero).
m_uDetectedArraySize
Unused. Value is always 0 (zero).
m_puDetectedFeatures
Unused. Value is always NULL.
m_uSelectListSize
Number of elements listed in a SELECT clause. For example, in the statement SELECT a,b,c FROM d, m_uSelectListSize is the value 3 (a, b and c).
m_ppSelectList
Structure used to store property names. This field is used with the m_uSelectListSize field. For example, in the statement SELECT a,b,c FROM d, m_uSelectListSize is 3, and the m_ppszNameList field of the m_ppSelectList structure contains the strings "a", "b" and "c". For more information, see SWbemQueryQualifiedName.
m_uFromTargetType
Bitmap used to indicate the form of the FROM clause.
WMIQ_RPN_FROM_UNARY (1 (0x1))
FROM clause contains a single class.
WMIQ_RPN_FROM_PATH (2 (0x2))
FROM clause contains an object path.
WMIQ_RPN_FROM_CLASS_LIST (4 (0x4))
FROM clause contains a list of classes.
m_pszOptionalFromPath
Optional FROM path. If not used this field is NULL.
m_uFromListSize
Number of items in the FROM clause of the SELECT statement. For example, in the statement, SELECT * FROM a, b, the value of m_uFromListSize is 2.
m_ppszFromList
Pointer to a list of strings. Each string is one element of the FROM clause of a SELECT statement. For example, in the statement SELECT * FROM a, b, the list contains the strings "a" and "b".
m_uWhereClauseSize
Number of tokens in the WHERE clause. For example, in the statement SELECT * FROM a, b WHERE c < 1000 AND d ISA e, the value of m_uWhereClauseSize is 2 (the phrases c < 1000 and d ISA e).
m_ppRpnWhereClause
SWbemRpnQueryToken
SELECT * FROM a, b WHERE c < 1000 AND d ISA e
c < 1000
d ISA e
AND
m_dblWithinPolling
If there is a WITHIN clause, this field indicates the polling interval. If there is a GROUP WITHIN clause, this m_dblWithinPolling is unused.
m_dblWithinWindow
Used if there is a GROUP WITHIN clause to indicate the interval over which to group results.
m_uOrderByListSize
m_ppszOrderByList
m_uOrderDirectionEl
