如何将记录作为参数传递给 PL/pgSQL 函数?
我一直在网上寻找这个答案,但找不到。
我正在尝试通过 PL/pgSQL 函数传递一条记录。我尝试了两种方法。
拳头方式:
CREATE OR REPLACE FUNCTION translateToReadableDate(mRecord dim_date%ROWTYPE) RETURNS void AS $$
这就是输出:
psql:requestExample.sql:21: ERROR: syntax error at or near "%"
LINE 1: ... FUNCTION translateToReadableDate(mRecord dim_date%ROWTYPE) ...
^
第二种方式:
CREATE OR REPLACE FUNCTION translateToReadableDate(mRecord RECORD) RETURNS void AS $$
还有输出
psql:requestExample.sql:21: ERROR: PL/pgSQL functions cannot accept type record
有人知道怎么做吗?
CREATE OR REPLACE FUNCTION translateToReadableDate(mRecord dim_date) RETURNS void AS $$
BEGIN
SELECT dim_day.name || ' (' || dim_day_in_month.id || ') ' || dim_month.name || 'is the ' || dim_week.id || ' week of the year. ' AS "Une phrase", dim_quarter.id, dim_year.id
FROM dim_date dd
JOIN dim_day ON dd.day_id = dim_day.day_id
JOIN dim_day_in_month ON dd.day_in_month_id = day_in_month.day_in_month_id
JOIN dim_week ON dd.week_id = dim_week.week_id
JOIN dim_month ON dd.month_id = dim_month.month_id
JOIN dim_quarter ON dd.quarter_id = dim_quarter.quarter_id
JOIN dim_year ON dd.year_id = dim_year.year_id
WHERE dd.day_id = mRecord.day_id
AND dd.day_in_month_id = mRecord.day_in_month_id
AND dd.week_id = mRecord.week_id
AND dd.month_id = mRecord.month_id
AND dd.quarter_id = mRecord.quarter_id
AND dd.year_id = mRecord.year_id;
END;
$$ LANGUAGE plpgsql;
I keep looking for this answer online but I cannot find it.
I am trying to pass one record over a PL/pgSQL function. I tried it in two ways.
Fist way :
CREATE OR REPLACE FUNCTION translateToReadableDate(mRecord dim_date%ROWTYPE) RETURNS void AS $
That is the ouput :
psql:requestExample.sql:21: ERROR: syntax error at or near "%"
LINE 1: ... FUNCTION translateToReadableDate(mRecord dim_date%ROWTYPE) ...
^
Second way :
CREATE OR REPLACE FUNCTION translateToReadableDate(mRecord RECORD) RETURNS void AS $
And there is the output
psql:requestExample.sql:21: ERROR: PL/pgSQL functions cannot accept type record
Someone does know how to do this please ?
CREATE OR REPLACE FUNCTION translateToReadableDate(mRecord dim_date) RETURNS void AS $
BEGIN
SELECT dim_day.name || ' (' || dim_day_in_month.id || ') ' || dim_month.name || 'is the ' || dim_week.id || ' week of the year. ' AS "Une phrase", dim_quarter.id, dim_year.id
FROM dim_date dd
JOIN dim_day ON dd.day_id = dim_day.day_id
JOIN dim_day_in_month ON dd.day_in_month_id = day_in_month.day_in_month_id
JOIN dim_week ON dd.week_id = dim_week.week_id
JOIN dim_month ON dd.month_id = dim_month.month_id
JOIN dim_quarter ON dd.quarter_id = dim_quarter.quarter_id
JOIN dim_year ON dd.year_id = dim_year.year_id
WHERE dd.day_id = mRecord.day_id
AND dd.day_in_month_id = mRecord.day_in_month_id
AND dd.week_id = mRecord.week_id
AND dd.month_id = mRecord.month_id
AND dd.quarter_id = mRecord.quarter_id
AND dd.year_id = mRecord.year_id;
END;
$ LANGUAGE plpgsql;

试试这个:
dim_date 必须是一个表。
编辑:
好的,现在我真的很困惑。
最后,我建议阅读 PL/pgSQL 手册。里面有很多好东西。
Try this:
dim_date must be a table.
EDIT:
Ok, now I'm really really confused.
Lastly, I would recommend reading the PL/pgSQL Manual. There's lots of good stuff in there.
