I have a query that i need to save the results to a csv file and have that happen on a scheduled time.  I want to create a sql job that will do this and overwrite the file each time the job runs.

You could do this pretty easily with Powershell.

function GetSQL ($query)
{
    $Connection = new-object system.data.sqlclient.sqlconnection
    $Connection.ConnectionString = "server='servername';database='database';trusted_connection=true;"
    $Connection.open()
    $Command = New-Object System.Data.SqlClient.SqlCommand
    $Command.CommandText = $query
    $SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
    $SqlAdapter.SelectCommand = $Command
    $Command.Connection = $Connection
    $data = New-Object System.Data.DataTable
    $SqlAdapter.Fill($data) | Out-Null
    $Connection.Close()
    return, $data
}

$query = "SELECT * FROM Table"
$outFile = "C:\Path\out.csv"
$result = GetSQL $query
$result | Export-CSV $outFile -NoType

Open in new window


Just schedule that guy and off you go.

So, do i only need to change the $query = line and the $outFile = line?

Do i set that up as a job in SQL?

This is a powershell file, so you'd save the text as a .ps1 file and then you can schedule the job in Windows task scheduler.

You need to change $query, $outFile and then these 2

$Connection.ConnectionString = "server='servername';database='database';trusted_connection=true;"

To schedule the job, schedule the process powershell.exe -file and then the path to the .ps1 script after it.  i.e.:
powershell.exe -file c:\Scripts\thisScript.ps1

You also need to schedule it to run whether the user you create the task as is logged on or not.

i created the .ps1 file and setup the windows scheduled task.  I ran the task, it says it was successful, but i don't have a .csv file in my folder.  Do i need to remove the quotation marks around the query and file location?

Did you schedule the user to run the task with highest privileges?

Built in to windows is the Powershell ISE, can you open your .ps1 file with that and run it and see if it outputs any errors?  (on server 2012+ just type in "ise" at the start menu to pull it up.

i pulled up the .ps1 file using "ise", and ran the file.  I get an error that says:

File C:\files\customer.ps1 cannot be loaded because running scripts is disable on this system

Ok, you'll need to enable powershell on the system.

In ISE, open a new tab (the white page) and paste this:
Set-ExecutionPolicy RemoteSigned

Open in new window


Then go back to the script and try it again.

Ok, we are getting there.  That created the file.  The problem is it is putting quotation marks around all of my data in the file.  I would like it to put a pipe in between each column of data.

For example:
This is what it is doing
"Name", "Age", "Year"
"Smith", "55", "1965"
"Jones", "44", "1977"

I would like it to do this in the csv file
Name | Age | Year
Smith | 55 | 1965
Jones | 44 | 1977

I'm able to export the file like this in sql by changing the delimiter.

The quotes are a standard part of the CSV format, when you import a csv it'll ignore them.  but if you want the file to not have them we'd have to fudge the format with something like:

function GetSQL ($query)
{
    $Connection = new-object system.data.sqlclient.sqlconnection
    $Connection.ConnectionString = "server='server';database='database';trusted_connection=true;"
    $Connection.open()
    $Command = New-Object System.Data.SqlClient.SqlCommand
    $Command.CommandText = $query
    $SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
    $SqlAdapter.SelectCommand = $Command
    $Command.Connection = $Connection
    $data = New-Object System.Data.DataTable
    $SqlAdapter.Fill($data) | Out-Null
    $Connection.Close()
    return, $data
}

$query = "SELECT * FROM table"
$outFile = "C:\Path\out.csv"
$result = GetSQL $query
$result | ConvertTo-Csv -Delimiter "|" -NoTypeInformation | % {$_.Replace('"','')} | Out-File $outFile

Open in new window

You could also achieve this using SQLCMD.  Save your query as a .SQL file and then set a scheduled task to execute on the schedule(s) you want.

The SQLCMD would be something along the lines of

SQLCMD -S <servername> -E -d <databasename> -i <scriptfile> -h -1 -o <outputfile

This is something I have had to use on occasions to pass data between systems.
