.SYNOPSIS
Runs a T-SQL Query and optional outputs results to a delimited file.
.DESCRIPTION
Invoke-Sql script will run a T-SQL query or stored procedure and optionally outputs a delimited file.
.EXAMPLE
PowerShell.exe -File "C:\Scripts\Invoke-Sql.ps1" -ServerInstance "Z003\sqlprod2" -Database orders -Query "EXEC usp_accounts '12445678'"
This example connects to Z003\sqlprod2.Orders and executes a stored procedure which does not return a result set
.EXAMPLE
PowerShell.exe -File "C:\Scripts\Invoke-Sql.ps1" -ServerInstance "Z003\sqlprod2" -Database orders -Query "SELECT * FROM dbo.accounts" -FilePath "C:\Scripts\accounts.txt" -Delimiter ","
This example connects to Z003\sqlprod2.Orders and selects the records from the accounts tables, the data is outputed to a CSV file
