getQueryBandNumPairs(String QBandBuf, int QB_SearchType)

Syntax Elements

QBandBuf
A query band string, where the query band can be:
  • Returned by QueryBand.getQueryBand()
  • Retrieved from the DBC.DBQLogTbl.QueryBand column
  • Specified by the caller
QB_SearchType
Specifies whether getQueryBandNumPairs() searches for name-value pairs in the transaction, session, and/or profile query band.
If the value is...
  • QueryBand.QB_FIRST, then return the number of name-value pairs in the transaction, session, and profile query bands, where each name is unique. If the transaction, session, or profile query bands contain the same name, getQueryBandNumPairs() counts only one name-value pair.
  • QueryBand.QB_TXN, then return the number of name-value pairs in the transaction query band.
  • QueryBand.QB_SESSION, then return the number of name-value pairs in the session query band.
  • QueryBand.QB_PROFILE, then return the number of name-value pairs in the profile query band.
