我最近创建了一个定义如下的过程:
create or replace
PACKAGE
pkg_dml_legal_transactions
AS
PROCEDURE spm_update_court_cost(
p_court_state IN legal_court_cost.state%TYPE,
p_tran_code IN legal_court_cost.transaction_code%TYPE,
p_legal_court IN legal_court_cost.court%TYPE default null,
p_end_date IN legal_court_cost.end_date%TYPE,
p_cost_min IN legal_court_cost.cost_range_min%TYPE,
p_cost_max IN legal_court_cost.cost_range_max%TYPE,
p_bal_min IN legal_court_cost.bal_range_min%TYPE DEFAULT NULL,
p_bal_max IN legal_court_cost.bal_range_max%TYPE DEFAULT NULL);
end pkg_dml_legal_transactions;
当我尝试execute该过程时,我收到一个错误,指出:
PLS-00306: wrong number or types of arguments in call to 'SPM_UPDATE_COURT_COST'
这是我的execute语句的样子:
execute pkg_dml_legal_transactions.spm_update_court_cost('NJ',1,sysdate,1000,40000);
现在我明白了错误意味着什么,但我想如果参数默认为null然后我可以跳过它们,但显然不是.有没有解决的办法？
对于C#用户来说,这似乎是一个常见的问题,经过研究和多次尝试后,我无法从字符串中删除一对括号.我遇到问题的字符串是Service (additional).
在做完我的研究之后,我理解括号的处理方式不同Regex.Replace.我的研究也得到了我尝试的多个答案,但似乎没有任何效果.以下是我尝试删除这些括号的一些方法.
cleanValue = Regex.Replace(intVal, " ", "").Replace("(", "").Replace(")", "").Replace(",", "").Replace("/", "").Replace("-", "");
cleanValue = Regex.Replace(intVal, " ", "").Replace(@"\(", "").Replace(@"\)", "").Replace(",", "").Replace("/", "").Replace("-", "");
cleanValue = Regex.Replace(intVal, " ", "").Replace("[()]", "").Replace(",", "").Replace("/", "").Replace("-", "");
cleanValue = Regex.Replace(intVal, " ", "").Replace(@"[^a-zA-Z]", "").Replace(",", "").Replace("/", "").Replace("-", "");
这些都没有奏效,在单步执行代码后,我只看到'e'和'之间的空格('删除了.我错过了什么？
如果有人想看到function这里使用的是:
public static string CleanExtra(string intVal)
{
string cleanValue;
if (intVal == null)
{
throw new System.ArgumentException("Value cannot be null", "original");
}
else
{
//cleanValue = Regex.Replace(intVal, " …我正在尝试学习C#,我是一个使用布尔值的例子.对于我的生活,我无法弄清楚为什么程序没有注意到我试图将值传递给布尔值.这是Form.cs中的代码:
namespace WindowsFormsApplication7
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button2_Click(object sender, EventArgs e)
{
HappyBirthday birthdayMessage = new HappyBirthday();
string returnedMessage;
birthdayMessage.PresentCount = 5;
birthdayMessage.MyProperty = "Adam";
birthdayMessage.hasParty = true;
returnedMessage = birthdayMessage.MyProperty;
MessageBox.Show(returnedMessage);
}
}
}
这是我创建的类:
class HappyBirthday
{
//====================
// CLASS VARIABLES

private int numberOfPresents;

//birthdayParty = false;
}

我遇到了一个我似乎无法弄清楚的错误.当我尝试将excel数据加载到消息框中时,我得到了这个:
Retrieving the COM class factory for component with CLSID {00020819-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).
此错误出现在:
Microsoft.Office.Interop.Excel.Workbook workbook = new Microsoft.Office.Interop.Excel.Workbook();
我已经对这个特定错误进行了研究,并尝试了我发现的所有内容.我曾试图改变Platform Target的属性x86像有些人取消选中一起说Prefer 32-bit,离开Platform Target的Any CPU.我想我可能会错过一个重要的参考,但注意到我已经有了.NET Microsoft.Office.Interop.Excel,当我尝试添加COM等效时,它没有帮助.作为参考,我使用的是32位Windows操作系统.
任何关于为什么会出现此错误的帮助将不胜感激.谢谢.
以下是该类中的完整代码:
