class PG::TextDecoder::CopyRow - pg-0.18.4 Documentation

# class PG::TextDecoder::CopyRow

This class decodes one row of arbitrary columns received as COPY data in text format. See the COPY command for description of the format.

It is intended to be used in conjunction with PG::Connection#get_copy_data .

The columns are retrieved as Array of values. The single values are decoded as defined in the assigned type_map. If no type_map was assigned, all values are converted to strings by PG::TextDecoder::String.

Example with default type map ( TypeMapAllStrings ):

    deco = PG::TextDecoder::CopyRow.new
    conn.copy_data "COPY my_table TO STDOUT", deco do
      while row=conn.get_copy_data
        p row
      end
    end

This prints all rows of `my_table` to stdout:

    ["astring", "7", "f"]
    ["string2", "42", "t"]
