Example 8—Writable External Table with gpfdist

Creates a writable external table, sales_out, that uses gpfdist to write output data to the file sales.out. The column delimiter is a pipe ( | ) and NULL (‘ ‘) is a space. The file will be created in the directory specified when you started the gpfdist file server.

  1. =# CREATE WRITABLE EXTERNAL TABLE sales_out (LIKE sales) 
  2.    LOCATION ('gpfdist://etl1:8081/sales.out')
  3.    FORMAT 'TEXT' ( DELIMITER '|' NULL ' ')
  4.    DISTRIBUTED BY (txn_id);
