Answer 1

In your Windows PowerShell command prompt the code does not require variable setting or anything fancy. Just do this:

sqlplus ElBankoUser\SupaSecretyPass "@C:\Users\ElBankoUser\Documents\MaFancySckrp.sql"

Answer 2

You can use .NET Oracle library DLL, just make sure you have the required DLL file under the lib folder

Add-Type -Path "lib\Oracle.ManagedDataAccess.dll"

$query = "select  1 as Col1, 2 as Col2, 3 as Col3 from dual
          union
          select  4 as Col1, 5 as Col2, 6 as Col3 from dual
          union
          select  7 as Col1, 8 as Col2, 9 as Col3 from dual"

$cn   = New-Object Oracle.ManagedDataAccess.Client.OracleConnection -ArgumentList "TNS-ConnectionString-Here"
$cmd  = New-Object Oracle.ManagedDataAccess.Client.OracleCommand    -ArgumentList $query

$cmd.Connection = $cn

try {
    $cn.Open()

    $reader = $cmd.ExecuteReader()

    while ($reader.Read()) {
        $col1 = $reader["Col1"]
        $col2 = $reader["Col2"]
        $col3 = $reader["Col3"]

        Write-Host $col1, $col2, $col3
    }

} catch {
    Write-Error $_.Exception.Message
} finally {
    $cmd.Dispose()
    $cn.Dispose()
}

I use the call operator, &, as Keith Hill has suggested with the question, How to run an EXE file in PowerShell with parameters with spaces and quotes.

& 'path\sqlplus.exe' 'system/password@dbase as sysdba'

I placed the username, password in quotes due to the spaces.

To start a script, I add another parameter as follows:

 & 'path\sqlplus.exe' 'system/password@dbase as sysdba' '@my_script.sql'

If you are receiving the ORA-12154 error, and you know that other users have established connections (which implies that the database listener is running properly); I would then examine if SQL*Plus can find my tnsname file.

My first task would be to see if I can tnsping as follows in Windows cmd.exe:

tnsping orcl

It will confirm that a connection can (or can not be established).

If it cannot, I would check to see if the environment variable, ORACLE_HOME, is set. SQL*Plus uses this to find tnsname.ora file.

If it is not set, I would execute this statement in PowerShell (to establish this environment variable):

[Environment]::SetEnvironmentVariable("ORACLE_HOME", "C:\app\Administrator\product\11.2.0\client_1" , "User")

Next, I would retry to tnsping (identified above).

Once successful, I would re-try to execute the script running command above.

Answer 4

I use this:

$cmd = "cmd.exe"
$args = ("/c sqlplus {0}/{1}@{2}:{3}/{4} @{5} {6}" -f $userName, $password, $tnsAlias, $port, $dbInstance, $sqlScript, $outputFileName)
&$cmd $args 

Answer 5

Why not use this?

sqlplus -s $adminLogin "@C:\Users\Administrator\Desktop\oracle\OracleCleanTest.sql"

-s just suppresses the sqlplus banner.
