Asp.net 无法将数据插入数据库，未显示错误消息

我无法将数据插入数据库，并且没有收到错误消息。通过将

patientRIC

声明为外键，我链接了表

patientRegister

和

patientMission

。下面是代码

patientNOK.cs

 public class patientNOK

 string wardPreference = ddl1.SelectedValue;

        string admissionDischargeDT = adDT.Text;

我试着查看日志文件，它显示了这一点，显然NOK类存在问题

异常类型：System.Data.SqlClient.SqlException异常： “patientNokGender”附近的语法不正确。资料来源： patientNOKDAO.InsertNOK sql命令：插入PatientMission( wardClass，admissiont，patientNokFname，patientNokLname， patientNokNRIC，patientNOKDOB patientNokGender，PatientNokNational， patientNokRelationship，patientNokContactH，patientNokContactHP， PatientNokMail patientNokAddr1，patientNokAddr2，patientNokZIP， patientNokCountry、放电时间、PatientRic）值 （@parawardClass、@paraadmissond、@parapatientNokFname、@parapatientNokLname、@parapatientNokNRIC、， @parapatientNOKDOB、@parapatientnokender、@parapatientnokenantity @parapatientNokRelationship、@parapatientNokContactH、@parapatientNokContactHP、@parapatientNokEmail、@parapatientNokAddr1、@parapatientNokAddr2、@parapatientNokState、@parapatientNokZIP @parapatientNokCountry，@paradischargeDateTime，@parapatientNRIC）

您可以测试最终生成的sql命令吗。

在这类问题中，我在microsoft sql server中的一个新查询中运行了sqlCmd。

在字符串连接的某些点上，似乎缺少逗号，第一个是：

患者无性别

另一个是：

patientNokEmail patientNokAddr1

原因如下：

sqlStr.AppendLine("Insert INTO patientAdmission( wardClass, admissionDT, patientNokFname, patientNokLname, patientNokNRIC, patientNOKDOB");

sqlStr.AppendLine("patientNokGender, patientNokNationality, patientNokRelationship, patientNokContactH, patientNokContactHP, patientNokEmail");

---

您还需要确保将逗号添加到值字符串连接中。

更新下面的行-

sqlStr.AppendLine("Insert INTO patientAdmission( wardClass, admissionDT, patientNokFname, patientNokLname, patientNokNRIC, patientNOKDOB");
sqlStr.AppendLine("patientNokGender, patientNokNationality, patientNokRelationship, patientNokContactH, patientNokContactHP, patientNokEmail");
sqlStr.AppendLine("patientNokAddr1, patientNokAddr2, patientNokZIP, patientNokCountry, dischargeDateTime,patientNRIC)");
sqlStr.AppendLine("VALUES (@parawardClass,@paraadmissonDT,@parapatientNokFname,@parapatientNokLname,@parapatientNokNRIC, @parapatientNOKDOB,@parapatientNokGender,@parapatientNokNationality");
sqlStr.AppendLine("@parapatientNokRelationship,@parapatientNokContactH,@parapatientNokContactHP,@parapatientNokEmail,@parapatientNokAddr1,@parapatientNokAddr2,@parapatientNokState,@parapatientNokZIP");
sqlStr.AppendLine("@parapatientNokCountry,@paradischargeDateTime,@parapatientNRIC)");

在第一行、第二行、第四行和第五行添加“，”以确保正确的SQL格式。

尝试调试并检查日志。执行代码时，

result

的值是多少？您好，我实际上是如何做到的？亲爱的@GX-X请在该行result=您的sqlCmnd上插入断点，然后运行应用程序。然后复制sqlCmd的值并粘贴到MicrosoftSQLServer中的新sql查询窗口中并运行它。

sqlStr.AppendLine("Insert INTO patientAdmission( wardClass, admissionDT, patientNokFname, patientNokLname, patientNokNRIC, patientNOKDOB, ");
sqlStr.AppendLine("patientNokGender, patientNokNationality, patientNokRelationship, patientNokContactH, patientNokContactHP, patientNokEmail, ");
sqlStr.AppendLine("patientNokAddr1, patientNokAddr2, patientNokZIP, patientNokCountry, dischargeDateTime,patientNRIC)");
sqlStr.AppendLine("VALUES (@parawardClass,@paraadmissonDT,@parapatientNokFname,@parapatientNokLname,@parapatientNokNRIC, @parapatientNOKDOB,@parapatientNokGender,@parapatientNokNationality, ");
sqlStr.AppendLine("@parapatientNokRelationship,@parapatientNokContactH,@parapatientNokContactHP,@parapatientNokEmail,@parapatientNokAddr1,@parapatientNokAddr2,@parapatientNokState,@parapatientNokZIP, ");
sqlStr.AppendLine("@parapatientNokCountry,@paradischargeDateTime,@parapatientNRIC)");
