在工作中我们常常需要使用powershell连接Oracle数据库。 但是在百度找到的代码都是很老的,而且还需要oracle数据库连接客户端。查找一番后发现Oracle官方早已经发布了对.net官方连接库,高效简单。 连接库地址: https://www.oracle.com/technetwork/developer-tools/visual-studio/overview/index.html

我写的小小demo: 官方文档: https://docs.oracle.com/cd/E11882_01/win.112/e23174/client.htm#ODPNT0008 用例:

 

$AssemblyFile = "Oracle.ManagedDataAccess.dll"
[Reflection.Assembly]::LoadFile($AssemblyFile)
$username = "xx" 
$password = "xx" 
$datasource = "192.168.xx.xx/dbname" 
$sql = "SELECT * from xxdb" 
$connectionnectionString = 'User Id=' + $username + ';Password=' + $password + ';Data Source=' + $datasource 
$connectionnection = New-Object Oracle.ManagedDataAccess.Client.OracleConnection($connectionnectionString) 
$connectionnection.open() 
$command=$connection.CreateCommand() 
$command.CommandText=$sql 
$da = New-Object Oracle.ManagedDataAccess.Client.OracleDataAdapter($command) 
$builder=New-Object Oracle.ManagedDataAccess.Client.OracleCommandBuilder($da) #用来更新数据库 
$ds = New-Object system.Data.DataSet [void]$da.fill($ds,"xxdb") 
foreach($row in $ds.Tables["xxdb"] ) 
{ 
 $row["xxFLAG"]="1" 
 $da.Update($ds,"xxdb") #更新数据库
 }
 $connection.close()
