ORA-00911:无效字符

Question

我在我的oracle(11g)数据库中创建了两个表,如下所示:

    create table "test" ("id" int);
    create table test ("id" int);

然后在我的C#程序中出现了一个问题:

    OracleConnection conn = new OracleConnection(-myConnectionString-);
    conn.Open();
    OracleCommand command = new OracleCommand("select * from test;", conn);
    var v = command.ExecuteReader(); 
    OracleCommand command = new OracleCommand("select * from \"test\";", conn);
    var v = command.ExecuteReader(); 

对于command.ExecuteReader()我有一个"ORA-00911:无效字符"错误.

Answer 1

去掉 ; 从SQL字符串的末尾开始(分号)

Answer 2

如果其他人在这里寻找如何在单个命令中包含多个语句,则需要将语句包装在开始和结束中.这将停止由于冒号导致的无效字符错误.例如:

var command = new OracleCommand(@"
    begin
    select * from test;
    select * from test2;
    end;")
