如何运行简单的选择查询并在雪花过程中获得结果？

CREATE OR REPLACE PROCEDURE COARSDB0P_DB.COUNT_MISMATCH() 
RETURNS VARCHAR  
LANGUAGE JAVASCRIPT  
AS  
$$  
var command ="SELECT b.TABLE_CATALOG,b.TABLE_SCHEMA,b.TABLE_NAME,b.TABLE_TYPE,b.ROW_COUNT as Dev_COUNT,a.ROW_COUNT as UAT_COUNT FROM TABLE A ,information_schema.tables B where b.TABLE_NAME=a.TABLE_NAMES and b.TABLE_SCHEMA=a.TABLE_SCHEMA and b.TABLE_TYPE=a.TABLE_TYPE and TRY_CAST(b.ROW_COUNT as NUMBER) != TRY_CAST(a.ROW_COUNT as NUMBER);"
var cmd1_dict = {sqlText: command};  
var stmt = snowflake.createStatement(cmd1_dict);  
var rs = stmt.execute();
rs.next();
var output = rs.getColumnValue();
  return output;
$$; 

我需要返回提到的 SELECT 查询的实际输出。

Answer 1

见Returning tabular data from a stored procedure。你会想要类似的东西

returns table (catalog varchar, schema varchar, ...)

Answer 2

您可以使用表格 SQL UDF 来返回结果：
