ISearchQueryHelper::get_QuerySelectColumns method

Gets the columns (or properties) requested in the SELECT statement of the query.

Syntax


HRESULT get_QuerySelectColumns(
  [out, retval] LPWSTR *ppszSelectColumns
);

Parameters

ppszSelectColumns [out, retval]

Type: LPWSTR*

Receives a pointer to a comma-delimited, null-terminated Unicode string that specifies the columns (or properties) to be returned from a query.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

Items are represented in the property store as a row. Each row contains a number of columns that represent properties for that row or object. Not all items will have a value for a particular property. Properties must be in the property store to be subject to a select operation.
