Vertica SQL 在一条语句中插入多行 [英] Vertica SQL insert multiple rows in one statement

问题描述

想知道是否可以在一个插入语句中完成以下操作?

Was wondering whether it's possible to accomplish the following in one insert statement?

drop table analytics.bw_covariance_matrix;
create table analytics.bw_covariance_matrix (
row int,
x1 float,
x2 float,
x3 float
);

insert into analytics.bw_covariance_matrix VALUES
(1, 4.01926965, -0.4686067, -0.07592112),
insert into analytics.bw_covariance_matrix VALUES
(2, -0.46860675,  4.1799267, -0.82461139);
insert into analytics.bw_covariance_matrix VALUES
(3, -0.07592112, -0.8246114,  4.37186211);

推荐答案

你可以 UNION 一个 SELECT 有一个 INSERT 语句:

You could UNION a SELECT to have a single INSERT statement:

insert into analytics.bw_covariance_matrix 
SELECT 1, 4.01926965, -0.4686067, -0.07592112
UNION
SELECT 2, -0.46860675,  4.1799267, -0.82461139
UNION
SELECT 3, -0.07592112, -0.8246114,  4.37186211

我不相信 Vertica 有像 MySQL 和其他 RDBMS 那样的多记录插入语句，所以这是最好的选择.

I don't believe that Vertica has a multi record insert statement like MySQL and other RDBMS's, so this is the best bet.
