Powershell script to validate sql syntax errors

Question

Is there any powershell syntax that detects sql syntax errors? For e.g. stored procedures , SQL query , functions etc.

You can wrap your query with PARSEONLY or NOEXEC, here's an example :

$Server = "SERVER"
$Database = "Database"
$UserId = "USERID"
$Password = "PASSWORD"
$QueryToTest= "SELECT * FROM NO_TABLE !!"

Function Check-Query-Syntax
{
    Param(
        [Parameter(Mandatory = $true)][string]$query
    )
    try
    {
        $sb = New-Object -TypeName "System.Text.StringBuilder"
        [void]$classpath.AppendLine("SET NOEXEC ON;")
        [void]$classpath.AppendLine($query)
        [void]$classpath.AppendLine("SET NOEXEC OFF;")
        $Connection = New-Object System.Data.SQLClient.SQLConnection
        $Connection.ConnectionString = "server='$Server';database='$Database';User Id='$UserId';Password='$Password';trusted_connection=true;"
        $Connection.Open()
        $Command = New-Object System.Data.SQLClient.SQLCommand
        $Command.Connection = $Connection
        $Command.CommandText = $SQLQuery
        $Reader = $Command.ExecuteNonQuery()
        $Connection.Close()
    }
    catch
    {
        Write-Host "Some error"
        throw
    }
}

Check-Query-Syntax $QueryToTest

PARSEONLY NOEXEC

UPDATE :

If you want to check the queries inside .sql files then execute the script from the directory that contains the scripts

Get-ChildItem .\*.sql | Select -ExpandProperty FullName | ForEach { $query = (Get-Content -Path $_); Check-Query-Syntax $str }
