如何获取在线系统中最后一位注册员工的信息? [英] How to get information for the last registered employee in online system?
问题描述
假设我已经注册了一名员工
InsertEmployee();
现在，下一条语句我想获取该最后一位注册雇员的信息，因为我的要求是根据该雇员的入职日期计算的，因此我需要计算一些值. //此代码在asp.cs文件中的autoid
私人void Autoid()
{
字符串模式="M";
pr.Mode =模式;
dt = new DataTable();
dt = logic.Maxid(pr);
if(dt.Rows [0] [0] .ToString()！=")
{
txtEMPId.Text =(int.Parse(dt.Rows [0] [0] .ToString())+1).ToString();
}
其他
txtRMPId.Text ="1";
}
//inclass cs文件
公共DataTable InsertEmployeeFormat(ParametersBusinessObjects Schbo)
{
DataTable dt = new DataTable();
DataAcessHelper dashp =新的DataAcessHelper();
如果(Schbo.Mode！="M")
{
SqlCommand cmd = dashp.CreateCommand("sp_Employeedetails");
dashp.AddParameter(cmd，"@EmpIdid"，SqlDbType.Int，ParameterDirection.Input，4，Schbo.School);
dashp.AddParameter(cmd，"@EmpName"，SqlDbType.VarChar，ParameterDirection.Input，30，Schbo.SchoolName);
dashp.AddParameter(cmd，"@LandlineNo"，SqlDbType.VarChar，ParameterDirection.Input，20，Schbo.LandlineNo);
dashp.AddParameter(cmd，"@MobileNo"，SqlDbType.VarChar，ParameterDirection.Input，20，Schbo.MobileNo);
dashp.AddParameter(cmd，"@Address"，SqlDbType.VarChar，ParameterDirection.Input，30，Schbo.Address);
dashp.AddParameter(cmd，"@ DateofBirth"，SqlDbType.Date，ParameterDirection.Input，30，Schbo.strDate);
dashp.AddParameter(cmd，"@EndDate"，SqlDbType.Date，ParameterDirection.Input，30，Schbo.EndDate);
dashp.AddParameter(cmd，"@Flag"，SqlDbType.VarChar，ParameterDirection.Input，2，Schbo.Mode);
if(Schbo.Mode！="A" && Schbo.Mode！="S" && Schbo.Mode！="G" && Schbo.Mode！="N")
{
dashp.ExecuteStoredProcedure(cmd);
}
其他
{
dt = dashp.GetDataTable(cmd);
}
}
其他
{
SqlCommand cmd = dashp.CreateCommand("sp_maxid");
dt = dashp.GetDataTable(cmd);
}
return dt;
}
//存储过程
ALTER PROCEDURE sp_maxid
/*
(
@ parameter1 int = 5，
@ parameter2数据类型OUTPUT
)
*/

从EmployeeDetailsInfo中选择max(intEmployeeId)
返回
你试试这个.............
hai，
试试这个想法.，
使用select查询查找该表上的最大id并从前端获取它.
像这样的代码:
----------------
con.open();
字符串se =从表名中选择max(uid)";
sqlcommand cmd =新的sqlcommand(se，con);
int lastid = convert.ToInt32(cmd.executescalar());
con.close();
现在您可以获得lastid值...
我希望这对您有用...
再见
您可以在InsertEmployee操作期间生成一个名为"CreatedOn"的字段.下一条语句可以基于CreatedOn字段获取最近的数据.
Suppose I have registered an employee
InsertEmployee();
Now next statement I want to get information for that last registered employee because my requirement is according to the date of joining of that employee I need to calculate some value.
//this code in asp.cs file for autoid
private void Autoid()
{
string Mode = "M";
pr.Mode = Mode;
dt = new DataTable();
dt = logic.Maxid(pr);
if (dt.Rows[0][0].ToString() != "")
{
txtEMPId.Text = (int.Parse(dt.Rows[0][0].ToString()) + 1).ToString();
}
else
txtRMPId.Text = "1";
}
//inclass cs file
public DataTable InsertEmployeeFormat(ParametersBusinessObjects Schbo)
{
DataTable dt = new DataTable();
DataAcessHelper dashp = new DataAcessHelper();
if (Schbo.Mode != "M")
{
SqlCommand cmd = dashp.CreateCommand("sp_Employeedetails");
dashp.AddParameter(cmd, "@EmpIdid", SqlDbType.Int, ParameterDirection.Input, 4, Schbo.School);
dashp.AddParameter(cmd, "@EmpName", SqlDbType.VarChar, ParameterDirection.Input, 30, Schbo.SchoolName);
dashp.AddParameter(cmd, "@LandlineNo", SqlDbType.VarChar, ParameterDirection.Input, 20, Schbo.LandlineNo);
dashp.AddParameter(cmd, "@MobileNo", SqlDbType.VarChar, ParameterDirection.Input, 20, Schbo.MobileNo);
dashp.AddParameter(cmd, "@Address", SqlDbType.VarChar, ParameterDirection.Input, 30, Schbo.Address);
dashp.AddParameter(cmd,"@DateofBirth",SqlDbType.Date,ParameterDirection.Input ,30, Schbo.strDate);
dashp.AddParameter(cmd, "@EndDate", SqlDbType.Date, ParameterDirection.Input, 30, Schbo.EndDate);
dashp.AddParameter(cmd, "@Flag", SqlDbType.VarChar, ParameterDirection.Input, 2, Schbo.Mode);
if (Schbo.Mode != "A" && Schbo.Mode != "S" && Schbo.Mode != "G" && Schbo.Mode !="N")
{
dashp.ExecuteStoredProcedure(cmd);
}
else
{
dt = dashp.GetDataTable(cmd);
}
}
else
{
SqlCommand cmd = dashp.CreateCommand("sp_maxid");
dt = dashp.GetDataTable(cmd);
}
return dt;
}
//stored procedure
ALTER PROCEDURE sp_maxid
/*
(
@parameter1 int = 5,
@parameter2 datatype OUTPUT
)
*/
AS
select max(intEmployeeId) from EmployeeDetailsInfo
RETURN
u try this.............
hai,
try this idea.,
use select query on find maximum id on that table and get it from front end.
code like this:
----------------
con.open();
string se="select max(uid) from tablename";
sqlcommand cmd=new sqlcommand(se,con);
int lastid=convert.ToInt32(cmd.executescalar());
con.close();
now you can get lastid value...
i hope this is useful to you...
take care bye bye
You can generate a field named ''CreatedOn'' during InsertEmployee operation. Next statement can fetch the l(e)ast data based on CreatedOn field.
