我正在雪花中编写查询以从不同的表和视图中获取数据，然后想将输出组合到一个视图中以便其他人可以访问它

Question

CREATE TEMPORARY TABLE sales AS
SELECT
    PRODUCT_SKU,
    sum(GROSS_SALES - GROSS_RETURNS - COUPON_DISCOUNT) total_sales_ttm,
    sum(GROSS_MARGIN) as gross_margin_ttm,
    avg(COST_OF_GOODS_SOLD - COST_OF_RETURNS) as avg_cost_ttm,
    sum(QUANTITY_SOLD - QUANTITY_RETURNED) as unit_sold_ttm
FROM TABLE1 
WHERE
TRAN_DATE BETWEEN (CURRENT_DATE -365) AND CURRENT_DATE
GROUP BY 1;

CREATE TEMPORARY TABLE q_sales AS
SELECT 
    PRODUCT_SKU,
    sum(GROSS_SALES_AMOUNT - GROSS_RETURNS_AMOUNT) q_total_sales_ttm,
    sum(GROSS_MARGIN) as q_gross_margin_ttm,
    avg(COST_OF_GOODS_SOLD - COST_OF_RETURNS) as q_avg_cost_ttm,
    sum(QUANTITY_SOLD - QUANTITY_RETURNED) as q_unit_sold_ttm
FROM TABLE2 
WHERE
TRAN_DATE BETWEEN (CURRENT_DATE -365) AND CURRENT_DATE
GROUP BY 1;

CREATE TEMPORARY TABLE prices AS
SELECT 
    rp.SKU, 
    rp.PRICE AS RETAIL_PRICE,
    bp.PRICE AS BASELINE_PRICE
FROM TABLE3 rp
LEFT JOIN TABLE4 bp 
ON rp.SKU=bp.SKU
WHERE
rp.history=1 AND bp.history=1;

//将临时表合并为一个查询

SELECT
    sales.PRODUCT_SKU, 
    total_sales_ttm, gross_margin_ttm, avg_cost_ttm,
    q_total_sales_ttm, q_gross_margin_ttm, q_avg_cost_ttm,
    retail_price,baseline_price
FROM
sales
LEFT JOIN q_sales
ON sales.PRODUCT_SKU = q_sales.PRODUCT_SKU
LEFT JOIN prices
ON sales.PRODUCT_SKU=prices.SKU

Answer 1

您可能希望使用临时表而不是临时表，因为临时表在会话中限定范围。

然后您可以将这些 views/tables 合并到一个视图中，并让具有 SELECT 访问权限的角色访问最终视图，这样具有该角色的用户就可以 read-only 访问查看。

如果你能在这里进一步澄清你的问题，可以提供更好的帮助。

Answer 2

所以如果我制作一些测试数据表：

CREATE TABLE sales AS
SELECT
    1 as PRODUCT_SKU,
    10 as total_sales_ttm,
    11 as gross_margin_ttm,
    5 as avg_cost_ttm,
    4 as unit_sold_ttm
;

CREATE TABLE q_sales AS
SELECT 
    1 as PRODUCT_SKU,
    12 as q_total_sales_ttm,
    13 as q_gross_margin_ttm,
    14 as q_avg_cost_ttm,
    15 as q_unit_sold_ttm
;

CREATE TEMPORARY TABLE prices AS
SELECT 
    1 as SKU, 
    42 AS RETAIL_PRICE,
    43 AS BASELINE_PRICE

你的select:

SELECT
    sales.PRODUCT_SKU, 
    total_sales_ttm, gross_margin_ttm, avg_cost_ttm,
    q_total_sales_ttm, q_gross_margin_ttm, q_avg_cost_ttm,
    retail_price,baseline_price
FROM
sales
LEFT JOIN q_sales
ON sales.PRODUCT_SKU = q_sales.PRODUCT_SKU
LEFT JOIN prices
ON sales.PRODUCT_SKU=prices.SKU;

给出：

PRODUCT_SKU	TOTAL_SALES_TTM	GROSS_MARGIN_TTM	AVG_COST_TTM	Q_TOTAL_SALES_TTM	Q_GROSS_MARGIN_TTM	Q_AVG_COST_TTM	RETAIL_PRICE	BASELINE_PRICE
1	10	11	5	12	13	14	42	43

从而做出看法：

CREATE VIEW view_name as 
SELECT
    sales.PRODUCT_SKU, 
    total_sales_ttm, gross_margin_ttm, avg_cost_ttm,
    q_total_sales_ttm, q_gross_margin_ttm, q_avg_cost_ttm,
    retail_price,baseline_price
FROM
sales
LEFT JOIN q_sales
ON sales.PRODUCT_SKU = q_sales.PRODUCT_SKU
LEFT JOIN prices
ON sales.PRODUCT_SKU=prices.SKU;

因此：

select PRODUCT_SKU, TOTAL_SALES_TTM, GROSS_MARGIN_TTM from view_name;

给出：

PRODUCT_SKU	TOTAL_SALES_TTM	GROSS_MARGIN_TTM
1	10	11

您需要确保其他用户有权访问视图所在的 database/schema，并授予运行视图的权限，因此也授予表的权限..
