在 where 子句中使用通配符的 Snowflake 函数参数
Snowflake function parameters with wildcard in where clause
您知道为什么以下函数调用在参数内使用通配符时不起作用吗?
CREATE OR REPLACE FUNCTION ABC("CUSTCODE" VARCHAR, "CUSTNAME" VARCHAR)
RETURNS TABLE ("CUSTOMER_CODE" VARCHAR, CUSTOMERNAME VARCHAR)
LANGUAGE SQL
AS $$
SELECT CUSTOMER_CODE, CUSTOMERNAME FROM DIM_CUSTOMER
WHERE CUSTNAME is null AND CUSTOMER_CODE ILIKE '%CUSTCODE%'
$$;
我没有收到任何错误,但也没有找到任何记录
似乎不喜欢喜欢的“%CUSTCODE%”位
谢谢
您的代码块内有单引号 '
,但代码块标有单引号。所以以太交换成双倍美元 $$
CREATE OR REPLACE FUNCTION ABC("CUSTCODE" VARCHAR)
RETURNS TABLE ("CUSTOMER_CODE" VARCHAR, CUSTOMERNAME VARCHAR)
LANGUAGE SQL
AS $$
SELECT CUSTOMER_CODE, CUSTOMERNAME FROM DIM_CUSTOMER
WHERE CUSTOMER_CODE ILIKE '%CUSTCODE%'
$$;
或者在里面使用双单..
CREATE OR REPLACE FUNCTION ABC("CUSTCODE" VARCHAR)
RETURNS TABLE ("CUSTOMER_CODE" VARCHAR, CUSTOMERNAME VARCHAR)
LANGUAGE SQL
AS '
SELECT CUSTOMER_CODE, CUSTOMERNAME FROM DIM_CUSTOMER
WHERE CUSTOMER_CODE ILIKE ''%CUSTCODE%''
';
