Jruby代码截断雪花表

Question

这是我用来连接到雪花数据库的代码：

require 'java'
require 'rubygems'
require 'C:/Program Files/CData/CData JDBC Driver for Snowflake 2018/lib/cdata.jdbc.snowflake.jar'

url = "jdbc:snowflake:User=Admin;Password=test123;Server=localhost;Database=Northwind;Warehouse=TestWarehouse;Account=Tester1;"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Id, ProductName FROM Products")
while (rs.next) do
  puts rs.getString(1) + ' ' + rs.getString(2)
end

但是我还需要运行其他SQL查询：

• sql_query1：Copy into table1 from table2
• sql_query2：Truncate table student

如何使用我的代码运行这些查询？

Answer 1

我认为您只会更新您的SQL

rs = stmt.executeQuery("SELECT Id, ProductName FROM Products")

将该SQL更改为您找到的示例以外的其他内容。
