Thread: Function with COPY command?

Is there any way to make this function work?

CREATE OR REPLACE FUNCTION import_text_file(char(255)) RETURNS void AS $$
DECLARE
     filename ALIAS FOR $1;
BEGIN
     COPY table FROM filename;
END;
$$ LANGUAGE plpgsql;

The version below works fine, but I need something like the above version.

CREATE OR REPLACE FUNCTION import_text_file(char(255)) RETURNS void AS $$
DECLARE
     filename ALIAS FOR $1;
BEGIN
     COPY table FROM 'C:\\somefile.txt';
END;
$$ LANGUAGE plpgsql;

Use EXECUTE.

            regards, tom lane

Something like this will help:

CREATE OR REPLACE FUNCTION import_text_file(char(255)) RETURNS void AS $$
DECLARE
    filename  ALIAS FOR $1;
    fin varchar;
BEGIN
    fin := 'COPY table from ' || filename;   
    execute fin;
END;
$$ LANGUAGE plpgsql;
