lookupBackwardForColumns method

Move backward through the table from the beginning, looking for a row that matches or is less than a value or partial set of values in the current index.

Boolean lookupBackwardForColumns( UInt16 numColumns )            
  • numColumns   For composite indexes, the number of columns to use in the lookup. For example, if you have a three column index, and you want to look up a value that matches based on the first column only, you should set the value for the first column, and then supply a numColumns value of 1.


true if successful, false otherwise.


To specify the value for which to search, set the column value for each column in the index. The cursor is left on the first row that matches or is less than the index value. On failure (no rows less than the value being looked for) the cursor position is before the first row (isBOF).

Each search must be preceded by a call to the lookupBegin method.
