I am trying to convert my sql query into a JSON format I have used FOR JSON PATH at the end and also FOR JSON AUTO but my results are getting cut off at the end. I cant show the output message but I can show my code with variables replaced. Any help would be greatly appreciated
using the powershell feature of ConvertTo-JSON was more effective than the for JSON path command in SQL . I recommend using ConvertTo-Json if using sql and powershell i found my answer here
http://mac-blog.org.ua/powershell-invoke-sqlcmd-convertto-json/
try using -MaxCharLength
So something like this
If (!(Get-Module -Name sqlps))
{
Push-Location
#Import-Module sqlps -DisableNameChecking
Pop-Location
}
If (!$userName) {
$SQLResponce = Invoke-Sqlcmd -ServerInstance $SQL_SERVER -MaxCharLength <some large enough number> -InputFile $SCRIPTPATH -Database 'webserver' -querytimeout 0
}
Else {
$SQLResponce = Invoke-Sqlcmd -ServerInstance $SQL_SERVER -MaxCharLength <some large enough number> -U $userName -P $password -InputFile $SCRIPTPATH -Database 'webserver' -querytimeout 0
}
$SQLResponce #Save this out to a file once you get it to be json in the responce

Below is my PowerShell script that connects to a remote SQL server and stored the result into a XML file.
$SQLResult = Invoke-Sqlcmd -inputfile $inputfile -ServerInstance $ServerInstance -Database $Database -Username $Username -Password $Password
$PropertyName = ($SQLResult | Get-Member -MemberType Property | Where {$_.Name -like "XML*"}).Name
$SQLResult.$PropertyName | Out-File -FilePath "C:\Temp\ExportFile.xml" -Force
Ideally it should return sth clean and neat like this (Which is also the case when I open up the result in my SQL Server Management Studio):
<Text>
<Data>I am happy</Data>
</Text>
However, when I open the file, it gives me:
<Text><Data>I am happy</Data></Text>
I have tried to use Export-Clixml, but the XML returned is surrounded by some meaningless tags called <props> which is not one of my tags.
Can anyone help me out on this, not sure which way to go to save it in its original format.
Use an XmlWriter to format and indent it nicely when writing back to disk:
# Create settings object, make sure we get the indentation
$writerSettings = [System.Xml.XmlWriterSettings]::new()
$writerSettings.Indent = $true
try{
# Create the writer
$writer = [System.Xml.XmlWriter]::Create("C:\Temp\ExportFile.xml", $writerSettings)
# Convert your XML string to an XmlDocument,
# then save the document using the writer
([xml]$SQLResult.$PropertyName).Save($writer)
}
finally {
# discard writer (closes the file handle as well)
$writer.Dispose()
}
I have not an Expert in power shell. I Need a script/Approch which handles the below requirement.
I have list of files in a folder and the file Names like below.
001_File.sql
002_File.sql
003_File.sql
004_File.sql
Also, I have a table in sql server which holds the file Name Information.
TableName: Executedfile with a column FileName.
002_File.sql
004_File.sql
My requirement is to read the files which is available in the folder but not in the table.
I have to the Read files only:
001_File.sql
003_File.sql
Now, I Need to Execute these two file in the sequential order under the same Transaction on SQL Server. As I Need to rollback all the transaction if any Error occurred.
As of now I wrote a power shell something below.
$QueryResult = Invoke-Sqlcmd -ServerInstance 'MyServer' -Database 'MyDb' -Query "SELECT DISTINCT FNames from TableName"
Get-ChildItem "E:\Testing\" -Filter *.sql | Sort-Object $_.Name|
Foreach-Object {
$FileFullpath= $_.FullName
Write-Host $FileFullpath
$FileName = $_.Name
Write-Host $FileName
if(!$QueryResult.FName.Contains($FileName))
{
invoke-sqlcmd -inputfile $FileFullpath -serverinstance "servername\serverinstance" -database "mydatabase"
}
}
Please suggest me some script.
Challenges:
How to read the files in Sequential order as it has leading Zeros. Does the Above `Sort-Object $_.Name ' will Sort ?
How to Execute all the list of files under one transaction.
Thanks
Finally I did something like this.
$QueryResult = Invoke-Sqlcmd -ServerInstance 'MyServer' -Database 'MyDb' -Query "SELECT DISTINCT FNames from TableName"
$FullScript = #()
$FullScript += "BEGIN TRANSACTION;"
Get-ChildItem "E:\Testing\" -Filter *.sql | Sort-Object $_.Name|
Foreach-Object {
if(!$QueryResult.FName.Contains($_.Name))
{
$FullScript += Get-Content $_.FullName
}
}
$FullScript += "COMMIT TRANSACTION;"
sqlcmd -S localhost -d test -Q "$FullScript"
Try this...
#get list of filenames from database...
$QueryResult = Invoke-Sqlcmd -ServerInstance 'MyServer' -Database 'MyDB' -Query "SELECT DISTINCT FNames from TableName" | Select-Object -ExpandProperty FileName
#get files from folder whose names are not in $queryresult...
$files = Get-ChildItem -Path E:\Testing -Filter *.sql | ? {(!($QueryResult.Contains($_.BaseName)))} | Sort-Object Name
#get the content of each $file and replace "GO" with empty string, etc...
$queries = #()
foreach ($file in $files) {
$queries += (Get-Content $file.FullName).replace("GO","")
}
#join each query into a single T-SQL statement...
$singleTransaction = $queries -join ";"
#execute statement...
Invoke-Sqlcmd -ServerInstance 'SERVER' -Database 'DB' -Query $singleTransaction
To really achieve a 'single transaction'...you may have to have a consistent input to modify and put into one statement. I am not sure how you will need to do that.
Finally I wrote the Script using SMO Objects to handle the GO Statement and Transactions.
$SqlFilePath = "D:\Roshan\Testing\SQL\"
$serverName = "MyServer"
$databaseName = "MyDB"
$QueryResult = Invoke-Sqlcmd -ServerInstance $serverName -Database $databaseName -Query "SELECT DISTINCT FName from dbo.TableName" -AS DataRows
$connection = new-object system.data.SqlClient.SQLConnection("Data Source=$serverName;Integrated Security=SSPI;Initial Catalog=$databaseName;Connection Timeout=600;Max Pool Size=10");
$Server = new-Object Microsoft.SqlServer.Management.Smo.Server(New-Object Microsoft.SqlServer.Management.Common.ServerConnection($connection))
$script_contents ="SET XACT_ABORT ON
GO
BEGIN TRANSACTION
GO"
Get-ChildItem $SqlFilePath -Filter *.sql| Sort-Object $_.Name|
ForEach-Object {
if(!$QueryResult.FName.Contains($_.Name))
{
Write-Host $_.Name -ForegroundColor Magenta
#[string]$script_contents = Get-Content $_.FullName
$script_contents += [IO.File]::ReadAllText($_.FullName)
#Write-Host $script_contents
#$Server.ConnectionContext.ExecuteNonQuery($script_contents)
}
}
$script_contents+= " COMMIT TRANSACTION;"
$Server.ConnectionContext.ExecuteNonQuery($script_contents)
You can write some thing in your shell script
select filename from tablename; >> file.out
--->002_File.sql
grep -v 'file.out' * >> excludedfile.out
My PowerShell script keeps failing when trying to import a CSV file.
The error message reads: "Invoke-Sqlcmd : Conversion failed when converting date and/or time from character string."
In my CSV file, I have a column called "LastWriteTime"
Here is my PowerShell script
$database = 'test'
$server = 'leasesql'
$table = 'dbo.ssis'
Import-CSV C:\temp\text.csv | ForEach-Object {
Invoke-Sqlcmd -Database $database -ServerInstance $server -Query "INSERT INTO $table (PSComputerName, FullName, Extension, LastWriteTime)
VALUES ('$_.PSComputerName','$_.FullName','$_.Extension','$_.LastWriteTime,')"
}
I was able to find out that I need to put the columns in $($_.colmunname)
Import-CSV C:\temp\ssis.csv | ForEach-Object {
Invoke-Sqlcmd -Database $database -ServerInstance $server -Query "INSERT INTO $table VALUES ('$($.PSComputerName)','$($.FullName)','$($.Extension)','$($.LastWriteTime)')"
I have a script that executes a stored procedure on a SQL Server which returns XML. I then have a function to to format the XML in powershell so it is readable. When i open the XML in Chrome i get this error:
This page contains the following errors:
error on line 149 at column 27: Encoding error
Below is a rendering of the page up to the first error.
I think I may need to encode it in UTF8 but I am unsure where to do it in my code. Any help to rectify the error or how to do the encoding is appreciated.
Here is the Powershell that I run to get the XML file:
function Format-XML {
[CmdletBinding()]
Param ([Parameter(ValueFromPipeline=$true,Mandatory=$true)][string]$xmlcontent)
$xmldoc = New-Object -TypeName System.Xml.XmlDocument
$xmldoc.LoadXml($xmlcontent)
$sw = New-Object System.IO.StringWriter
$writer = New-Object System.Xml.XmlTextwriter($sw)
$writer.Formatting = [System.XML.Formatting]::Indented
$xmldoc.WriteContentTo($writer)
$sw.ToString()
}
$Date = Get-Date -format "yyyyMMdd_HHmm"
$File = "C:\Temp\MyFile"+$Date+".xml"
$Query = "EXEC dbo.usp_MyProc"
$resultRow = Invoke-Sqlcmd -Query $Query -database MyDatabase -ServerInstance MyServer
Format-xml $resultRow['results'] | Set-Content -Path $File -Force
Comment "Try appending -Encoding UTF8 to your last line" from Martin Brandi worked
I need a way to execute a SQL (by importing a .SQL script) on a remote Oracle DB using PowerShell. In addition to this I am also trying to output the results in an .xls format in a desired folder location. To add to the fun, I would also want to run this task on an automatic schedule. Please help !
I have gotten so far :
[System.Reflection.Assembly]::LoadWithPartialName ("System.Data.OracleClient") | Out-Null
$connection = "my TNS entry"
$queryString = "my SQL query"
$command = new-Object System.Data.OracleClient.OracleCommand($queryString, $connection)
$connection.Open()
$reader = $command.ExecuteReader()
$tempArr = #()
#read all rows into a hash table
while ($reader.Read())
{
$row = #{}
for ($i = 0; $i -lt $reader.FieldCount; $i++)
{
$row[$reader.GetName($i)] = $reader.GetValue($i)
}
#convert hashtable into an array of PSObjects
$tempArr+= new-object psobject -property $row
}
$connection.Close()
write-host "Conn State--> " $connection.State
$tmpArr | Export-Csv "my File Path" -NoTypeInformation
$Error[0] | fl -Force
The easiest way is to drive sqlplus.exe via powershell. To execute the sql and get the output you do this:
$result = sqlplus.exe #file.sql [credentials/server]
#parse result into CSV here which can be loaded into excel
You can schedule this script with something like:
schtasks.exe /create /TN sqlplus /TR "Powershell -File script.ps1" /ST 10 ...
For this you need to have sqlplus installed (it comes with oracle express and you could install it without it). This obviously introduces dependency that is not needed but sqlplus could be used to examine the database and do any kind of thing which might be good thing to have around.
