Usage Notes

GetQueryBandPairs are two overloaded table functions. One requires the query band string to be passed in; the other uses internal calls to retrieve the query band.

Both functions are created in the SYSLIB database by the DEM DIP script. EXECUTE privileges are granted to PUBLIC by default. For more information, see Requirements for Using the API.
