Powershell script executing SQL procedure with parameters has truncated output - sql

Question

I have a Powershell script that is successfully connecting to a SQL Server database and executing a procedure. The SQL procedure contains a select as follows:
SELECT #sql AS 'ColDemo1'
The variable #sql is nvarchar(max). I want the full contents of #sql returned to a new sql file however I only get the first line and an unwanted column heading as below:
ColDemo1
------------
First line of data...
The Powershell script is as follows:
$server = "SERVER\DEMO"
$database = "dbDemo"
$pZero = "PVal0"
$pOne = "PVal1"
$pTwo = "PVal2"
$pThree = "PVal3"
function Run-SQLUSP {
param (
$pZero,
$pOne,
$pTwo,
$pThree
)
$conn = New-Object System.Data.SqlClient.SqlConnection("Server=${server};Database='${database}';Integrated Security=TRUE")
$conn.Open()
$cmd = $conn.CreateCommand()
$cmd.CommandText = "dbo.demoSp '$pZero', '$pOne', '$pTwo', '$pThree'"
$adapter = New-Object System.Data.SqlClient.SqlDataAdapter($cmd)
$dataset = New-Object System.Data.DataSet
[void]$adapter.Fill($dataset)
$dataset.tables[0]
}
Run-SQLUSP $pZero $pOne $pTwo $pThree | Out-File "c:\DemoFolder\DemoScriptName.sql" -width 8000
How can I amend my Powershell script to return all lines of the output to the new sql file? When executing the procedure in SSMS the resultset is returned in a single table cell (not multiple rows).

Answer 1

Two changes were required:
To avoid truncating the output: Change Out-File to Set-Content -Path and remove -width 8000.
To only return the first cell: Append .rows[0][0] to $dataset.tables[0] within the function.
Below is the revised code in full:
$server = "SERVER\DEMO"
$database = "dbDemo"
$pZero = "PVal0"
$pOne = "PVal1"
$pTwo = "PVal2"
$pThree = "PVal3"
function Run-SQLUSP {
param (
$pZero,
$pOne,
$pTwo,
$pThree
)
$conn = New-Object System.Data.SqlClient.SqlConnection("Server=${server};Database='${database}';Integrated Security=TRUE")
$conn.Open()
$cmd = $conn.CreateCommand()
$cmd.CommandText = "dbo.demoSp '$pZero', '$pOne', '$pTwo', '$pThree'"
$adapter = New-Object System.Data.SqlClient.SqlDataAdapter($cmd)
$dataset = New-Object System.Data.DataSet
[void]$adapter.Fill($dataset)
$dataset.tables[0].rows[0][0]
}
Run-SQLUSP $pZero $pOne $pTwo $pThree | Set-Content -Path "c:\DemoFolder\DemoScriptName.sql"

Answer 2

I was having the same issue, then discovered I could fix it if I used the Column Name to access the cell value from the table row.
#Trunacted
$data.Tables[0].Rows[0][0]
#Complete data
$data.Tables[0].Rows[0]["XMLData"]
