| Syntax | BlankIndex IndexName [,UserName, NoInstance] |
| Action | [Statement] Deletes all the entries for a query index. |
| Scope | Usable anywhere |
| Notes | Query indexes hold references to certain records. This statement (which must be in the appropriate sub table) deletes all references from the query index, IndexName and effectively empties it. If the UserName is supplied, the index instance for that user is emptied, rather than the one for the current user. Blankindex has an additional optional parameter NoInstance which defaults to false and if true deletes the index instance if it exists, rather than creating it if necessary and deleting any index entries. The system workarea SysError is set to a non-zero value if an error occurs, otherwise zero. |
