findPreviousForColumns method

Continues a findLast search by moving backward through the table from the current position, looking to see if the previous row exactly matches a value or partial set of values in the current index.

Syntax
Boolean findPreviousForColumns(
  UInt16 numColumns
)
            
Parameters
  • 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.

Returns

true if successful, false otherwise.

Remarks

The cursor is left on the previous row if it exactly matches the index value. On failure the cursor position is before the first row (isBOF).

The findPrevious method behavior is undefined if the column values being searched for are modified during a row update.
