以下是我通过PowerShell运行的Oracle查询。如果我在该机器上本地运行它，它工作正常，没有错误。
[Reflection.Assembly]::LoadFile("E:\oracle\product\11.2.0\ODP.NET\bin\2.x\Oracle.DataAccess.dll")
$constr = "User Id=system;Password=pass;Data Source=API"
$conn= New-Object Oracle.DataAccess.Client.OracleConnection($constr)
$conn.Open()
$sql="select * from dba_users"
$command = New-Object Oracle.DataAccess.Client.OracleCommand($sql,$conn)
$reader=$command.ExecuteReader()
while($reader.Read()){
$reader.GetString(0)
}
$conn.Close()
我想在这台机器的其他机器上运行相同的查询。我可以说我想远程运行它。
当我运行它时，我收到此错误：
异常通话＆＃34;打开＆＃34;用＆＃34; 0＆＃34;参数：＆＃34; ORA-12541：TNS：没有 听者＆＃34;
我无法在Tnsora文件中添加条目。
有人可以告诉我任何其他方法来实现这个目标吗？
答案 0 :(得分：1)
如果您无法修改tnsora，则必须使用// usage:
.some-element {
@include reset(margin, border, transform, width, visibility);
}
@mixin reset($properties...) {
@each $property in $properties {
#{$property}: map-get($defaults, $property);
}
}

或EZConnect作为connection string。试试这个：
connect descriptor
