我有一个原始表和mv,模式如下:
CREATE TABLE IF NOT EXISTS test.Income_Raw on cluster '{cluster}' (
Id Int64,
DateNum Date,
Cnt Int64,
LoadTime DateTime
) ENGINE==MergeTree
PARTITION BY toYYYYMMDD(LoadTime)
ORDER BY (Id, DateNum);
CREATE MATERIALIZED VIEW test.I
对不起,我的英语不好。我想将一个文件从桌面移动到用户的输入目的地。如果destination也有一个同名的文件,我如何要求用户重命名该文件,以便在destination文件夹中同时包含这两个文件?我现在有这个: #!bin/bash
echo "path"
read path
echo "Do you want to move code files somewhere else?"
read -t 5 y
if [[ $y = 'yes' ]] ; then
echo "Tell me where:"
read mydest
f
我使用mv命令丢失了一些文件。我不知道他们在哪。它们不在我打算将它们复制到的目录中。
以下是我所做的事情的记录:
samuelcayo@CAYS07019906:~/Downloads/221-tp2-public-main$ cd
samuelcayo@CAYS07019906:~$ ls

samuelcayo@CAYS07019906:~$ mkdir tp2

我正在尝试构建以下MV:
CREATE MATERIALIZED VIEW LOG ON EVENTS
WITH ROWID, SEQUENCE(AIRCRAFT, MONTHS_YEARS) INCLUDING NEW VALUES;
CREATE MATERIALIZED VIEW LOG ON MANTEINANCE
WITH ROWID, SEQUENCE(AIRCRAFT, MONTHS_YEARS) INCLUDING NEW VALUES;
CREATE MATERIALIZED VIEW MV_LOGBOOK
BUILD IMMEDIATE
