The SQL function is a utility that is used by several SQL import methods. This function may be added and used as needed.


This routine imports a delimited file into a table containing up to 30 columns.

  • @FileName - The path and name of the file to import
  • @Delimiter - Optional - The delimiter, which is a tab character by default
  • Table(ID, Col01, Col02, … Col30)

-- Description: This stored procedure imports a file FROM the disk.
--              The contents of the file are returned either
--                  a) in a table with a single columns
--                  b) or a delimited table with up to 30 columns
-- Returns:
--                  a) Table (value : VARCHAR(2000));
--                  b) Table (rowid : int, value01 : VARCHAR(2000), value02 : VARCHAR(2000), ... value30 : VARCHAR(2000));
