I want to read a file that contains a line separated list of *.sql file names (all located at the same directory) to execute the following:
$reader = [System.IO.File]::OpenText("_Scripts.txt")
try {
for(;;) {
$line = $reader.ReadLine()
if ($line -eq $null) { break }
#output
$out = $line.split(".")[0] + ".txt" ;
# -serverinstance u should change the value of it according to use
invoke-sqlcmd -inputfile $line -serverinstance "." | format-table | out-file -filePath $out
$line
}
}
finally {
$reader.Close()
}
I'm trying to execute this script file by using a batch file containing the command:
powershell.exe -ExecutionPolicy Bypass -Command "_scripts.ps1"
but I get the error shown below:
Can anyone help me fix my ps1 script please?
This works for me:
$lines = Get-Content C:\Temp\TEST\_Scripts.txt
ForEach ($line in $lines)
{
$out = $line.split(".")[0] + ".txt" ;
Invoke-Sqlcmd -InputFile $line -ServerInstance "localhost" -Database "master" | Format-Table | Out-File -FilePath $out
}

hi i am running the following query in powershell:
Import-Module Hall.psm1
$Database = 'Report'
$Server = '192.168.1.2'
$Query = 'SELECT all * FROM [Report].[dbo].[TestView]'
$LogLocation = "\\Report\LogFile.csv"
$DynamicYear = (Get-Date).Year
$DynamicMonth = (Get-Culture).DateTimeFormat.GetMonthName((Get-Date).Month)
$FileDestination = "\\Report\MONTHLY REPORTS\"+$DynamicYear+"\"+$DynamicMonth+"\"
$Outputfilename='TestView-'+(Get-Date).ToString('MM-dd-yyyy')+'.csv'
$LocalCreate = 'C:\Scripts\LocalCreate\'
$FolderPathExtension = "Microsoft.PowerShell.Core\FileSystem::"
$CodeDestination = $FolderPathExtension+$FileDestination
$filedest=$LocalCreate+$outputfilename
$Logfile = $FolderPathExtension+$LogLocation
Invoke-sqlcmd -querytimeout 120 -query "
$Query
" -database $database -serverinstance $server |
ConvertTo-Csv -NoTypeInformation | # Convert to CSV string data without the type metadata
Select-Object -Skip 0 | # Trim header row, leaving only data columns
% {$_ -replace '"',''} | # Remove all quote marks
Set-Content -Path $filedest
(gc $filedest) | ? {$_.trim() -ne "" } | set-content $filedest
if(Test-Path ($filedest)) {
Move-Item -Path $filedest -Destination $CodeDestination -Force
$LogType = 'INFO'
$LogEntry = "$filedest MovedTo $To"
Write-Log -Message $LogEntry -Level $LogType -Logfile $Logfile
}
which works fine without any issue if the query has data.
however, if the query does not have any data it does not create a .csv. how can i get it to create a blank .csv? or .csv with headers only?
Use New-Item -ItemType File -Path $filedest before your Invoke-SqlCmd Or ConvertTo-Csv
I have a Powershell script to read .sql files from a specific folder and run them against a database depending on the name of the filename.
The filenames are always the same: myDatabase.script.SomeRandomCharacters.csv
There can be many files which is why the script has a foreach loop.
[CmdletBinding()]
param (
[parameter(Mandatory = $true)][ValidateSet('dev')][String]$serverName,
[parameter(Mandatory = $true)][String]$databaseName,
)
$dir = Split-Path $MyInvocation.MyCommand.Path
$scripts = Get-ChildItem $dir | Where-Object { $_.Extension -eq ".sql" } | Where-Object { $_.Name -like "$databaseName*" }
foreach ($s in $scripts) {
$script = $s.FullName
Invoke-Sqlcmd -ServerInstance $serverName -Database $databaseName -InputFile $script
}
The issue here is that if I would have 2 databases "myDatabase" and "myDatabase2", running the script with the former input would run the latter as well since the Where-Object filtering uses an asterisk.
I can't figure out how to modify the script so that I get the absolute value of whatever is before the first fullstop in the filename. What I would also what to do is to validate the value between the first and second fullstops, in the example filename it is script.
Any help is appreciated!
Use the database names to construct a regex pattern that will match either:
param(
[Parameter(Mandatory = $true)][ValidateSet('dev')][String]$ServerName,
[Parameter(Mandatory = $true)][String[]]$DatabaseNames,
)
# Construct alternation pattern like `db1|db2|db3`
$dbNamesEscaped = #($DatabaseNames |ForEach-Object {
[regex]::Escape($_)
}) -join '|'
# Construct pattern with `^` (start-of-string anchor)
$dbNamePattern = '^{0}' -f $dbNamesEscaped
# Fetch scripts associated with either of the database names
$scripts = Get-ChildItem $dir | Where-Object { $_.Extension -eq ".sql" -and $_.Name -match $dbNamePattern }
# ...
You can use the StartsWith function to fix your filter:
$scripts = Get-ChildItem $dir | Where-Object { $_.Extension -eq ".sql" } | Where-Object { $_.Name.StartsWith("$($databaseName).") }
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
I'm Importing multiple CSV files into a SQL database.
What switches or additional functions can I use to skip the first 5 rows on the import?
Ive tried using Get-Content file.csv | Select -skip 5 | ConvertFrom-Csv -Header Name
but not sure how to add it to my code
$srcDir = "C:\PowerShell\Files"
Write-Output $srcDir
$files = Get-ChildItem $srcDir -Name -Attributes !Directory
foreach ($file in $files) {
echo $file
$filePath = $srcDir + '\' + $file
$delimiter = ','
$addTableName = $file -replace ".csv",""
$writeTableName = '"' + $addTableName + '"'
$dt = Import-Csv $filePath -Delimiter $delimiter | Out-DataTable
Write-Output $writeTableName
## Write-Output $dt.Columns
## Write-Output $dt.Columns
Add-SqlTable -ServerInstance "11.22.33.444\MSSQL" -Database "STAGE" -TableName $addTableName -DataTable $dt
Write-DataTable -ServerInstance "11.22.33.444\MSSQL" -Database "STAGE" -TableName $writeTableName -Data $dt
}
Get-ChildItem ".\Stored Procedures\*.sql" | ForEach-Object { sqlcmd -S ServerName -d DatabaseName -E -i $_.FullName }
When I run a batch of scripts from a folder with the above command, if a problem persists in the intermediate script (like create/Alter/DROP DML script in between) then it should stop there only and need to give me an error message.
You'll need to do a few things:
Set ErrorActionPreference to stop
Use the -b parameter with sqlcmd.exe utility
Capture and log or display output of sqlcmd.exe utility
I answered a similar a question on another forum and I've re-posted the answer here:
echo "select 'Good 1'" > C:\temp\scripts\1.sql
echo "select * from missingTable" > C:\temp\scripts\2.sql
echo "Select 'Good 3'" > C:\temp\scripts\3.sql
$ErrorActionPreference = "Stop"
ForEach ($S In Gci -Path "C:\Temp\Scripts\" -Filter *.sql | Sort-Object Name) {
try {
$result = SqlCmd -b -S $env:computername\sql1 -i $S.FullName
$result = $result -join "`n"
if ($LASTEXITCODE -ne 0) {
throw "$S.FullName : $lastexitcode : $result"
}
else {
write-output "Success: $($s.fullname) : $result" | Out-File C:\Temp\Scripts\sqllogging.txt -Append
}
}
catch {
write-output "Failed: $_ " | Out-File C:\Temp\Scripts\sqllogging.txt -Append
throw
}
}
