FindFirst(Int16) method

Moves forward through the table from the beginning, looking for a row that exactly matches a value or partial set of values in the current index.

Visual Basic
Public Function FindFirst( _
   ByVal numColumns As Short _
) As Boolean
public bool FindFirst(
   short numColumns
  • numColumns   For composite indexes, the number of columns to use in the find. 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 value of 1.

Return value

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 exactly matches the index value. On failure, the cursor position is after the last row (ULDataReader.IsEOF).

Each search must be preceded by a call to FindBegin.
