Postgresql plpgsql函數語法錯誤

我想創建一個函數來返回一組記錄，但我得到一個語法錯誤。查詢正在工作，但是當我將它嵌入到函數中時，出現錯誤。可以做什麼來返回集？Postgresql plpgsql函數語法錯誤

Error
ERROR: syntax error at or near "select"
LINE 27: select id, user_id, project_id, record_date, parselid, pars...

如果使用PLPGSQL，你必須包括begin/endstatements，您必須使用RETURN QUERY ... RETURN;按照該doc。

否則，您可以切換到使用SQL而不是PLPGSQL，並且您的函數將按原樣運行。

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