Operators for AddPostProcessing Method

Note

Indexing Service is no longer supported as of Windows XP and is unavailable for use as of Windows 8. Instead, use Windows Search for client side search and Microsoft Search Server Express for server side search.

 

The following list describes the operators for the IQuery::AddPostProcessing method.

DBOP_prior_command_tree

Used when adding post-processing operations. This operator occurs in the post-processing tree but never in a complete command tree. It has either no inputs, or no table- or scalar-valued expressions, depending on the previous command tree.

DBOP_add_columns

Used when adding post-processing operations, this operation is the only operation that can add columns "projected away" by earlier operations, such as columns from tables that already participate in the query. The inputs are a table and a projection list; output is a table.
