需要检查表中的某些标志是否有效

如果只有标志处于活动状态，则应执行更新语句。（我的标志是HR_Active和User_Active如果只有那些标志是“1”更新语句应该执行）如果“0”应该通过web服务的通道。

表名是：HS_HR_EMPLOYEE

下面我有提到我的代码片段。

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.Services; 
using System.Data; 
using System.Configuration; 
using System.Data.SqlClient; 

namespace XXX_WebService 
{ 

    [WebService(Namespace = "http://XXXXXXX.com/")] 
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] 
    [System.ComponentModel.ToolboxItem(false)] 

    public class EmployeeService : System.Web.Services.WebService 
    { 


     [WebMethod(Description = "Update Employee Email Address")] 
     public int Update(string USRACC_USER_ID, string EMP_OFFICE_EMAIL) 
     { 
      string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString; 
      using (SqlConnection con = new SqlConnection(constr)) 
      { 
       using (SqlCommand cmd = new SqlCommand("UPDATE HS_HR_EMPLOYEE SET EMP_OFFICE_EMAIL = @EMP_OFFICE_EMAIL FROM HS_SM_USER_ACCOUNT WHERE HS_SM_USER_ACCOUNT.EMP_NUMBER = HS_HR_EMPLOYEE.EMP_NUMBER AND USRACC_USER_ID = @USRACC_USER_ID")) 
       { 
        cmd.Parameters.AddWithValue("@USRACC_USER_ID", USRACC_USER_ID); 
        cmd.Parameters.AddWithValue("@EMP_OFFICE_EMAIL", EMP_OFFICE_EMAIL); 
        cmd.Connection = con; 
        con.Open(); 
        int row = cmd.ExecuteNonQuery(); 
        con.Close(); 
       //return row; 
       } 

       string emp_number ="-1"; 
       using (SqlCommand cmd = new SqlCommand("SELECT EMP_NUMBER FROM HS_SM_USER_ACCOUNT WHERE [email protected]_USER_ID")) 
       { 
        using (SqlDataAdapter sda = new SqlDataAdapter()) 
        { 
        cmd.Parameters.AddWithValue("@USRACC_USER_ID", USRACC_USER_ID); 
         cmd.Connection = con; 
         sda.SelectCommand = cmd; 
         using (DataTable dt = new DataTable()) 
         { 
          dt.TableName = "HS_SM_USER_ACCOUNT"; 
          sda.Fill(dt); 
          if(dt.Rows.Count > 0) 
          emp_number = dt.Rows[0][0]==DBNull.Value ? "-1" : dt.Rows[0][0].ToString(); 
         } 
        } 
       } 

       using (SqlCommand cmd = new SqlCommand("INSERT INTO HS_EMP_EMAIL_TEMP_LOG (EMP_NUMBER,USRACC_USER_ID,EMP_OFFICE_EMAIL,LOG_DATE_TIME) VALUES(@EMP_NUMBER,@USRACC_USER_ID,@EMP_OFFICE_EMAIL,GETDATE())")) 
       { 
        cmd.Parameters.AddWithValue("@EMP_NUMBER", emp_number); 
        cmd.Parameters.AddWithValue("@USRACC_USER_ID", USRACC_USER_ID); 
        cmd.Parameters.AddWithValue("@EMP_OFFICE_EMAIL", EMP_OFFICE_EMAIL); 
        cmd.Connection = con; 
        con.Open(); 
        int row = cmd.ExecuteNonQuery(); 
        con.Close(); 
        // return row; 
       } 
       return 1; 
      } 
     } 
    } 
}

在您的更新语句添加标志过滤器在where子句

UPDATE HS_HR_EMPLOYEE SET EMP_OFFICE_EMAIL = @EMP_OFFICE_EMAIL FROM HS_SM_USER_ACCOUNT WHERE HS_SM_USER_ACCOUNT.EMP_NUMBER = HS_HR_EMPLOYEE.EMP_NUMBER AND USRACC_USER_ID = @USRACC_USER_ID" and HS_HR_EMPLOYEE.HR_Active = 1 and User_Active = 1))

，或者你可以先使用select语句检查表的标志。
