解决“ORA-01036: 非法的变量名/编号“错误

刚才执行带参数据的SQL语句时报“ORA-01036: 非法的变量名/编号“错误。

错误代码如下:

    public static void ExecuteParameterSQL(string asName)

    {

        sConnectionString = ConfigurationManager.AppSettings.Get("UserConnection");

        OracleConnection ocConnection = new OracleConnection(sConnectionString);

        ocConnection.Open();

        OracleCommand ocCommand = ocConnection.CreateCommand();

        ocCommand.CommandType = CommandType.Text;

        ocCommand.CommandText = @"select EMPLOYEEID,EMPLOYEENAME from ORGANIZATION_EMPLOYEE where EMPLOYEENAME=@loginName";

        OracleParameter opName = new OracleParameter();

        opName.ParameterName = "loginName";

        opName.OracleType = OracleType.VarChar;

        opName.Value = asName;

        ocCommand.Parameters.Add(opName);

        int i = (int)ocCommand.ExecuteNonQuery();

        ocConnection.Close();

    }

去网上查了一下,原来问题出在SQL语句中参数定义不对。SQL server中用“@”定义参数,而Oracle中用“:”。

将SQL语句修改如下,运行没有问题。注意代码中红色部分。

 /// <summary>

    /// 执行参数

    /// </summary>

    /// <param name="asName"></param>

    public static void ExecuteParameterSQL(string asName)

    {

        sConnectionString = ConfigurationManager.AppSettings.Get("UserConnection");

        OracleConnection ocConnection = new OracleConnection(sConnectionString);

        ocConnection.Open();

        OracleCommand ocCommand = ocConnection.CreateCommand();

        ocCommand.CommandType = CommandType.Text;

        ocCommand.CommandText = @"select EMPLOYEEID,EMPLOYEENAME from ORGANIZATION_EMPLOYEE where EMPLOYEENAME=:loginName";

        OracleParameter opName = new OracleParameter();

        opName.ParameterName = "loginName";

        opName.OracleType = OracleType.VarChar;

        opName.Value = asName;

        ocCommand.Parameters.Add(opName);

        int i = (int)ocCommand.ExecuteNonQuery();

        ocConnection.Close();

    }:
