Powershell and Oracle: the strange couple

Here it is a nice guide to query an OracleDB using Powershell.
Basically install an Oracle Client (with .NET support), and define and use the following function (courtesy of PoshCode comunity):

function Get-OLEDBData ($connectstring, $sql) {            
   $OLEDBConn = New-Object System.Data.OleDb.OleDbConnection($connectstring)            
   $OLEDBConn.open()            
   $readcmd = New-Object system.Data.OleDb.OleDbCommand($sql,$OLEDBConn)            
   $readcmd.CommandTimeout = '300'            
   $da = New-Object system.Data.OleDb.OleDbDataAdapter($readcmd)            
   $dt = New-Object system.Data.datatable            
   [void]$da.fill($dt)            
   $OLEDBConn.close()            
   return $dt            
}

A test is here:

$connString = "password=pwd;User ID=id;Data Source=ambarabaciccicocco;Provider=OraOLEDB.Oracle"            
$query= "SELECT * FROM HR.DEPARTMENTS"            
Get-OLEDBData -connection $connString -sql $query

Powershell and SQL "GO" separator

When executing a SQL statement in Powershell that contains words like "GO" it generates the error:

"Incorrect syntax near 'GO' "

The explanation stands in the fact that GO is not a SQL keyword. It's a batch separator used by client tools (like SSMS) to break the entire script up into batches.

The solutions may be to break up the script into batches, with a script like this:

private static List getCommands(string testDataSql)

{

string[] splitcommands = File.ReadAllText(testDataSql).Split(new string[]{"GO\r\n"}, StringSplitOptions.RemoveEmptyEntries);

List commandList = new List(splitcommands);

return commandList;

}

Problem with COSBI OpenSource Mark

If the workload does not work, it's usually a problem related to the fact that COSBI cannot write the .ini file.

The problem is associated to missing drivers. Install all the drivers needed, and all will work fine :)
