How do I call a SQL Server stored procedure from PowerShell?

This answer was pulled from http://www.databasejournal.com/features/mssql/article.php/3683181

This same example can be used for any adhoc queries. Let us execute the stored procedure “sp_helpdb” as shown below.

$SqlConnection = New-Object System.Data.SqlClient.SqlConnection$SqlConnection.ConnectionString = "Server=HOME\SQLEXPRESS;Database=master;Integrated Security=True"$SqlCmd = New-Object System.Data.SqlClient.SqlCommand$SqlCmd.CommandText = "sp_helpdb"$SqlCmd.Connection = $SqlConnection$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter$SqlAdapter.SelectCommand = $SqlCmd$DataSet = New-Object System.Data.DataSet$SqlAdapter.Fill($DataSet)$SqlConnection.Close()$DataSet.Tables[0]

Here is a function that I use (slightly redacted). It allows input and output parameters. I only have uniqueidentifier and varchar types implemented, but any other types are easy to add. If you use parameterized stored procedures (or just parameterized sql...this code is easily adapted to that), this will make your life a lot easier.

To call the function, you need a connection to the SQL server (say $conn),

$res=exec-storedprocedure -storedProcName 'stp_myProc' -parameters @{Param1="Hello";Param2=50} -outparams @{ID="uniqueidentifier"} $conn

retrieve proc output from returned object

$res.data #dataset containing the datatables returned by selects

$res.outputparams.ID #output parameter ID (uniqueidentifier)

The function:

function exec-storedprocedure($storedProcName,          [hashtable] $parameters=@{},        [hashtable] $outparams=@{},        $conn,[switch]$help){         function put-outputparameters($cmd, $outparams){            foreach($outp in $outparams.Keys){                $cmd.Parameters.Add("@$outp", (get-paramtype $outparams[$outp])).Direction=[System.Data.ParameterDirection]::Output            }        }        function get-outputparameters($cmd,$outparams){            foreach($p in $cmd.Parameters){                if ($p.Direction -eq [System.Data.ParameterDirection]::Output){                $outparams[$p.ParameterName.Replace("@","")]=$p.Value                }            }        }        function get-paramtype($typename,[switch]$help){            switch ($typename){                'uniqueidentifier' {[System.Data.SqlDbType]::UniqueIdentifier}                'int' {[System.Data.SqlDbType]::Int}                'xml' {[System.Data.SqlDbType]::Xml}                'nvarchar' {[System.Data.SqlDbType]::NVarchar}                default {[System.Data.SqlDbType]::Varchar}            }        }        if ($help){            $msg = @"    Execute a sql statement.  Parameters are allowed.      Input parameters should be a dictionary of parameter names and values.    Output parameters should be a dictionary of parameter names and types.    Return value will usually be a list of datarows.     Usage: exec-query sql [inputparameters] [outputparameters] [conn] [-help]    "@            Write-Host $msg            return        }        $close=($conn.State -eq [System.Data.ConnectionState]'Closed')        if ($close) {           $conn.Open()        }        $cmd=new-object system.Data.SqlClient.SqlCommand($sql,$conn)        $cmd.CommandType=[System.Data.CommandType]'StoredProcedure'        $cmd.CommandText=$storedProcName        foreach($p in $parameters.Keys){            $cmd.Parameters.AddWithValue("@$p",[string]$parameters[$p]).Direction=                  [System.Data.ParameterDirection]::Input        }        put-outputparameters $cmd $outparams        $ds=New-Object system.Data.DataSet        $da=New-Object system.Data.SqlClient.SqlDataAdapter($cmd)        [Void]$da.fill($ds)        if ($close) {           $conn.Close()        }        get-outputparameters $cmd $outparams        return @{data=$ds;outputparams=$outparams}    }

Here is a function I use to execute sql commands. You just have to change $sqlCommand.CommandText to the name of your sproc and $SqlCommand.CommandType to CommandType.StoredProcedure.

function execute-Sql{    param($server, $db, $sql )    $sqlConnection = new-object System.Data.SqlClient.SqlConnection    $sqlConnection.ConnectionString = 'server=' + $server + ';integrated security=TRUE;database=' + $db     $sqlConnection.Open()    $sqlCommand = new-object System.Data.SqlClient.SqlCommand    $sqlCommand.CommandTimeout = 120    $sqlCommand.Connection = $sqlConnection    $sqlCommand.CommandText= $sql    $text = $sql.Substring(0, 50)    Write-Progress -Activity "Executing SQL" -Status "Executing SQL => $text..."    Write-Host "Executing SQL => $text..."    $result = $sqlCommand.ExecuteNonQuery()    $sqlConnection.Close()}
