Getting no query results in email - mysql

Question

This is my powershell script below. I am trying to export the query's results into email body. However, the email contains nothing except the table headers. Could anyone help out what could be wrong / incomplete?
# Create a DataTable
$table = New-Object system.Data.DataTable "bugs"
$col1 = New-Object system.Data.DataColumn bug_id,([string])
$col2 = New-Object system.Data.DataColumn bug_status,([string])
$col3 = New-Object system.Data.DataColumn resolution,([string])
$col4 = New-Object system.Data.DataColumn short_desc,([string])
$col5 = New-Object system.Data.DataColumn deadline,([string])
$table.columns.add($col1)
$table.columns.add($col2)
$table.columns.add($col3)
$table.columns.add($col4)
$table.columns.add($col5)
# This code defines the search string in the database table
$SQLQuery = "SELECT bug_id,
bug_status,
resolution,
short_desc,
deadline
FROM bugs
WHERE ( bug_status IN ( 'RESOLVED', 'VERIFIED', 'INTEST' )
AND deadline BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 30 DAY)
)
OR ( bug_status IN ( 'RESOLVED', 'VERIFIED', 'INTEST' )

Answer 1

You may have other problems, but the date arithmetic is definitely one issue.
MySQL has very strange rules about date arithmetic. The value of CURDATE() is not a date. It is either a string or a number. In a numeric context (CURDATE() + 9 is a numeric context), then it returns a number.
So, the date 2015-01-25 is returned as the integer 20150125. You can see this phenomenon on SQL Fiddle here. This value plus nine is 20150134. Not a valid date and not what you expect.
The easiest fix is to use date_add():
SELECT bug_id, bug_status, resolution, short_desc, deadline
FROM bugs
WHERE bug_status IN ('RESOLVED') AND
deadline BETWEEN CURDATE() AND date_add(CURDATE(), interval 9 day)

Answer 2

I was able to put this together from multiple sources that seems to work with any mySQL query you plug in accordingly. I figured I'd share in case anyone else finds it helpful. Seems to be reliable from what I tested at least. You don't need to build the HTML table in with the SQL logic this way.
## -- This will download the needed PS module and load it accordingly and then prompt you to save the mySQL credential to make the connection to the data source
## -- Run PowerShell as administrator
## https://mcpmag.com/articles/2016/03/02/querying-mysql-databases.aspx
Invoke-WebRequest -Uri https://github.com/adbertram/MySQL/archive/master.zip -OutFile 'C:\Users\user\desktop\MySQL.zip'
$modulesFolder = 'C:\Program Files\WindowsPowerShell\Modules'
Expand-Archive -Path C:\Users\user\desktop\MySQL.zip -DestinationPath $modulesFolder
Rename-Item -Path "$modulesFolder\MySql-master" -NewName MySQL
$dbCred = Get-Credential
Connect-MySqlServer -Credential $dbcred -ComputerName 'localhost' -Database sakila
## Enter the mySQL username and password when prompted
Invoke-MySqlQuery -Query 'SELECT * FROM actor'
## --This will run automated after the PS module used to make the mySQL is already loaded and not prompt for credential to allow non-interactive runs
## --Embedded credential used here
$secpasswd = ConvertTo-SecureString “password” -AsPlainText -Force
$dbCred = New-Object System.Management.Automation.PSCredential (“root”, $secpasswd)
Connect-MySqlServer -Credential $dbcred -ComputerName 'localhost' -Database sakila
Invoke-MySqlQuery -Query 'SELECT * FROM actor LIMIT 5'
## This runs the Function to do the alternating row colors in the HTML table
Function Set-AlternatingRows {
[CmdletBinding()]
Param(
[Parameter(Mandatory,ValueFromPipeline)]
[string]$Line,
[Parameter(Mandatory)]
[string]$CSSEvenClass,
[Parameter(Mandatory)]
[string]$CSSOddClass
)
Begin {
$ClassName = $CSSEvenClass
}
Process {
If ($Line.Contains("<tr><td>"))
{ $Line = $Line.Replace("<tr>","<tr class=""$ClassName"">")
If ($ClassName -eq $CSSEvenClass)
{ $ClassName = $CSSOddClass
}
Else
{ $ClassName = $CSSEvenClass
}
}
Return $Line
}
}
