Complete PowerShellScript for exporting Reports to Excel using ImportExcel
Takes a query from a SQL file, adds parameters to it, executes it on a SQL Server and writes the result into an Excel file. Return value 0 indicates successful execution, Return value -1 indicates errors.
This script enables exporting query results to excel from a machine, where Excel is not installed.
This is done leveraging the module ExcelPSLib.
System requirements:
- Powershell version 3 or greater with modules dbatools and ImportExcel installed
- SQL Server 2008 or greater
.PARAMETER databaseServer
Name of the database server the query should be executed on
.PARAMETER databaseName
Name of the database the query should be executed within
Path to a file with a SQL query.
.PARAMETER parameters
List of parameters with their assigned values in a DECLARE-statement.
This have to be the same parameters like those contained in the query (if any).
Typically queries running in a specified interval are parameterized regarding the time slice the information is needed for.
@dateTimeFrom DATETIME = '20190701 00:00',
@dateTimeTo DATETIME = '20190801 00:00'
(Base) Name for the generated file (default Export)
.PARAMETER fileNameSupplement
additional file name with separator (default timestamp): the defaults fileName Export and fileNameSupplement timestamp will resolve to something like "Export_20191126_144401.xlsx"
.PARAMETER worksheetName
name of the excel worksheet with the exported data (default Export)
.PARAMETER mailRecipient
Array of E-Mailadresses the report should be sent to. Example: '', ''
& X:\Scripts\exportReport.ps1 -fileNameSupplement '_201910' -parameters 'DECLARE @dateTimeFrom DATETIME = ''20191001'', @dateTimeTo DATETIME = ''20191101''' -databaseServer 'mydbserver' -databaseName 'mydb' -sqlFile 'X:\scripts\myexport.sql' -fileName 'myexport' -mailRecipient '', ''
