Hi!

How can i return one more row form a pgpl/sql function?

CREATE OR REPLACE FUNCTION GetRows(INTEGER, INTEGER, INTEGER) RETURNS
TEXT AS $$
    DECLARE
        Rows table_name%ROWTYPE;
    BEGIN
        SELECT * INTO Rows FROM table1_name WHERE id = $1;
        -- Return (1, 'Smis', 'smis@gmail.com')
        SELECT * INTO Rows FROM table2_name WHERE id = $2;
        -- Return (2, 'Ashle', 'Ashle@gmail.com')
        SELECT * INTO Rows FROM table3_name WHERE id = $3;
        -- Return (1, 'Galaxy University', 'g-uni@gmail.com')

        RETURN Rows;
    END;
$$ LANGUAGE 'plpgsql';

SELECT * FROM GetRows(1,2,3);

I want return for all 3 row in one table? How can i do that?

You can use a set-of-record - function for this:

http://www.postgresql.org/docs/current/static/xfunc-sql.html#XFUNC-SQL-TABLE-FUNCTIONS

or

http://www.postgresql.org/docs/8.1/interactive/plpgsql-control-structures.html#PLPGSQL-RECORDS-ITERATING

You should better use an array(int) for a variable count of parameters.
