Powershell中的MySQL超时 [英] MySQL timeout in powershell
问题描述
我在Windows笔记本电脑上安装了MySQL DB.我正在使用Powershell脚本来连接/查询/输入到数据库.我有一个要运行的查询，我可以在MySQL Workbench中运行它，目前需要31.032秒才能运行，并返回3行.
I have a MySQL DB setup on my Windows laptop. I'm using a powershell script to connect/query/input to the DB. I have a query I'm trying to run, I can run it in the MySQL Workbench currently it takes 31.032 sec to run and returns 3 rows.
SELECT puz1.sudoku9x9_id, puz1.difficulty, puz2.sudoku9x9_id, puz2.difficulty
FROM sudoku9x9 as puz1
INNER JOIN sudoku9x9 as puz2
WHERE
puz1.clue_9 = puz2.clue_1 AND puz1.region_9 = puz2.region_1 AND
puz1.difficulty/puz2.difficulty BETWEEN .84 AND 1.19 AND
NOT EXISTS (SELECT 1 FROM samurai2x AS a
WHERE
a.puz1_id = puz1.sudoku9x9_id AND a.puz2_id = puz2.sudoku9x9_id)
Powershell脚本
Powershell Script
$samurai2x = "SELECT puz1.sudoku9x9_id, puz1.difficulty, puz2.sudoku9x9_id, puz2.difficulty FROM sudoku9x9 as puz1 INNER JOIN sudoku9x9 as puz2 WHERE puz1.clue_9 = puz2.clue_1 AND puz1.region_9 = puz2.region_1 AND puz1.difficulty/puz2.difficulty BETWEEN .84 AND 1.19 AND NOT EXISTS (SELECT 1 FROM samurai2x AS a WHERE a.puz1_id = puz1.sudoku9x9_id AND a.puz2_id = puz2.sudoku9x9_id) LIMIT 1"
Invoke-MySqlQuery -Query $samurai2x | ForEach {
$diff = ([INT]$_.'difficulty' + [INT]$_.'difficulty1') / 2
Invoke-MySqlQuery -Query "INSERT INTO samurai2x(difficulty, puz1_id, puz2_id) VALUES ('$diff', '$($_.'sudoku9x9_id')', '$($_.'sudoku9x9_id1')')"
}
当我运行powershell脚本时，它超时.因此，我研究了更改超时选项.我先跑
When I run the powershell script, it times out. So I looked into changing the timeout options. I first ran
SET GLOBAL connect_timeout=31536000;
SET GLOBAL wait_timeout=2147483;
SET GLOBAL interactive_timeout=31536000;
数字是MySQL文档中允许的最大值.那没切！因此，我编辑了my.ini文件并添加了
The numbers are the max allowed from the MySQL documentation. That did not cut it! So I edited the my.ini file and added
[mysqld]
connect_timeout=31536000
wait_timeout=2147483
interactive_timeout=31536000
我重新启动了MySQL服务.还是同样的问题！
I restarted the MySQL service. Still the same issue!
当脚本连接到数据库时，它将显示
When the script connects to the DB it displays
ServerThread : 26
DataSource : localhost
ConnectionTimeout : 15
Database : sudoku
UseCompression : False
State : Open
ServerVersion : 5.7.17-log
ConnectionString : server=localhost;port=3306;user id=root;database=sudoku
IsPasswordExpired : False

在编辑超时之前和每次尝试之后，ConnectionTimeout始终显示15.
The ConnectionTimeout has always displayed 15 prior to editing the timeout and after every attempt.
我在这里想念什么?预先感谢您的帮助.
What am I missing here guys? Thanks in advance for the help.
# Set MySQL connection info
$username = "root"
$password = cat D:\Sudoku\mysecurestring.txt | convertto-securestring
$dbcred = new-object -typename System.Management.Automation.PSCredential `
-argumentlist $username, $password
# Connect to MySQL server
Connect-MySqlServer -Credential $dbcred -ComputerName localhost -Database sudoku
I'm connecting to the DB based on the steps at this site: Querying MySQL Databases with PowerShell
编辑
底部是修改后的功能.我在每个新行上方都添加了一个已添加"注释.
At the bottom is the modified function. I put a comment "Added" above each new line.
新连接线
Connect-MySqlServer -Credential $dbcred -ComputerName localhost -Database sudoku -CommandTimeOut 600 -ConnectionTimeOut 25
新连接输出

推荐答案
在Powershell脚本中的连接字符串中添加default command timeout=60;.
Add default command timeout=60; to the connection string in your Powershell script.
You may also want to set the CommandTimeout property of the MySqlCommand object.
