Postgresql plpgsql関数の構文エラー

Question

レコードセットを返す関数を作成したいが、構文エラーが出る。クエリは機能していますが、関数に埋め込んだときにエラーが発生します。セットを返すために何ができるのですか？

Answer 1

あなたがplpgsqlがを使用している場合、あなたはbegin/endstatementsを含める必要がありますし、あなたがdocあたりとしてRETURN QUERY ... RETURN;使用する必要があります。

それ以外の場合は、PLPGSQLの代わりにSQLを使用すると、機能はそのまま動作します。

CREATE OR REPLACE FUNCTION getloggeom([...]) 
    RETURNS SETOF record AS 
$BODY$ 
    [...] 
$BODY$ 
    LANGUAGE SQL 
    COST 1000 
    ROWS 1000;
