Advantage Client Engine
Determines if the given index order was built as a custom index.
UNSIGNED32 |
AdsIsIndexCustom (ADSHANDLE hIndex, UNSIGNED16 *pbCustom); |
hIndex (I) |
Handle of index order of interest. |
pbCustom (O) |
Return True if it is a custom index order. |
AE_INVALID_INDEX_TYPE |
NTX indexes cannot be custom. |
A custom index is built without keys. Keys are added to the custom index explicitly by calls to AdsAddCustomKey and AdsDeleteCustomKey. This allows a user to build a very small and specific index.
Custom indexes can only be built on tables opened with the ADS_CDX or ADS_ADT option.
