在清单 10 中的示例中，一个 SELECT 语句中的 WHERE 子句含有类型不兼容的操作数：STAFF 表的 JOB 列的数据类型是 VARCHAR，而不是 INTEGER。

                    
try
{
  ...
  cmd.Transaction = trans; 
  cmd.CommandText = "SELECT ID, NAME FROM STAFF WHERE JOB = 99";
  reader = cmd.ExecuteReader();    
  ...
}
catch (Exception ex)
{
  Console.WriteLine(ex.Message);
}

当 try 块中出现一个异常时，catch 块将捕获该异常。

ex.Message 包含异常的内容。含不兼容操作数的 SELECT 语句会生成以下异常：

ERROR [42818] [IBM][DB2/NT] SQL0401N  The data types of the operands for the 
operation "=" are not compatible.  SQLSTATE=42818

为了调试 DB2 ADO.NET 应用程序，可以使用 DB2 ADO.NET 跟踪实用程序。要激活 ADO.NET 跟踪实用程序，可以设置以下环境变量：

SET DB2NMPTRACE=1

DB2 .NET Provider 使用 DB2 CLI 的一些组件。这对于 DB2 ADO.NET 应用程序确定问题有时会很有用，可以获得 CLI 和 DB2 跟踪信息。

在清单 10 中的示例中，一个 SELECT 语句中的 WHERE 子句含有类型不兼容的操作数：STAFF 表的 JOB 列的数据类型是 VARCHAR，而不是 INTEGER。

                    
try
{
  ...
  cmd.Transaction = trans; 
  cmd.CommandText = "SELECT ID, NAME FROM STAFF WHERE JOB = 99";
  reader = cmd.ExecuteReader();    
  ...
}
catch (Exception ex)
{
  Console.WriteLine(ex.Message);
}

当 try 块中出现一个异常时，catch 块将捕获该异常。

ex.Message 包含异常的内容。含不兼容操作数的 SELECT 语句会生成以下异常：

ERROR [42818] [IBM][DB2/NT] SQL0401N  The data types of the operands for the 
operation "=" are not compatible.  SQLSTATE=42818

在清单 10 中的示例中，一个 SELECT 语句中的 WHERE 子句含有类型不兼容的操作数：STAFF 表的 JOB 列的数据类型是 VARCHAR，而不是 INTEGER。

                    
try
{
  ...
  cmd.Transaction = trans; 
  cmd.CommandText = "SELECT ID, NAME FROM STAFF WHERE JOB = 99";
  reader = cmd.ExecuteReader();    
  ...
}
catch (Exception ex)
{
  Console.WriteLine(ex.Message);
}

当 try 块中出现一个异常时，catch 块将捕获该异常。

ex.Message 包含异常的内容。含不兼容操作数的 SELECT 语句会生成以下异常：

ERROR [42818] [IBM][DB2/NT] SQL0401N  The data types of the operands for the 
operation "=" are not compatible.  SQLSTATE=42818

在清单 10 中的示例中，一个 SELECT 语句中的 WHERE 子句含有类型不兼容的操作数：STAFF 表的 JOB 列的数据类型是 VARCHAR，而不是 INTEGER。

                    
try
{
  ...
  cmd.Transaction = trans; 
  cmd.CommandText = "SELECT ID, NAME FROM STAFF WHERE JOB = 99";
  reader = cmd.ExecuteReader();    
  ...
}
catch (Exception ex)
{
  Console.WriteLine(ex.Message);
}

当 try 块中出现一个异常时，catch 块将捕获该异常。

ex.Message 包含异常的内容。含不兼容操作数的 SELECT 语句会生成以下异常：

ERROR [42818] [IBM][DB2/NT] SQL0401N  The data types of the operands for the 
operation "=" are not compatible.  SQLSTATE=42818

在清单 10 中的示例中，一个 SELECT 语句中的 WHERE 子句含有类型不兼容的操作数：STAFF 表的 JOB 列的数据类型是 VARCHAR，而不是 INTEGER。

                    
try
{
  ...
  cmd.Transaction = trans; 
  cmd.CommandText = "SELECT ID, NAME FROM STAFF WHERE JOB = 99";
  reader = cmd.ExecuteReader();    
  ...
}
catch (Exception ex)
{
  Console.WriteLine(ex.Message);
}

当 try 块中出现一个异常时，catch 块将捕获该异常。

ex.Message 包含异常的内容。含不兼容操作数的 SELECT 语句会生成以下异常：

在清单 10 中的示例中，一个 SELECT 语句中的 WHERE 子句含有类型不兼容的操作数：STAFF 表的 JOB 列的数据类型是 VARCHAR，而不是 INTEGER。

                    
try
{
  ...
  cmd.Transaction = trans; 
  cmd.CommandText = "SELECT ID, NAME FROM STAFF WHERE JOB = 99";
  reader = cmd.ExecuteReader();    
  ...
}
catch (Exception ex)
{
  Console.WriteLine(ex.Message);
}

当 try 块中出现一个异常时，catch 块将捕获该异常。

ex.Message 包含异常的内容。含不兼容操作数的 SELECT 语句会生成以下异常：

ERROR [42818] [IBM][DB2/NT] SQL0401N  The data types of the operands for the 
operation "=" are not compatible.  SQLSTATE=42818

在清单 10 中的示例中，一个 SELECT 语句中的 WHERE 子句含有类型不兼容的操作数：STAFF 表的 JOB 列的数据类型是 VARCHAR，而不是 INTEGER。

                    
try
{
  ...
  cmd.Transaction = trans; 
  cmd.CommandText = "SELECT ID, NAME FROM STAFF WHERE JOB = 99";
  reader = cmd.ExecuteReader();    
  ...
}
catch (Exception ex)
{
  Console.WriteLine(ex.Message);
}

当 try 块中出现一个异常时，catch 块将捕获该异常。

ex.Message 包含异常的内容。含不兼容操作数的 SELECT 语句会生成以下异常：

ERROR [42818] [IBM][DB2/NT] SQL0401N  The data types of the operands for the 
operation "=" are not compatible.  SQLSTATE=42818

DB2 .NET Provider 使用 DB2 CLI 的一些组件。这对于 DB2 ADO.NET 应用程序确定问题有时会很有用，可以获得 CLI 和 DB2 跟踪信息。

在清单 10 中的示例中，一个 SELECT 语句中的 WHERE 子句含有类型不兼容的操作数：STAFF 表的 JOB 列的数据类型是 VARCHAR，而不是 INTEGER。

                    
try
{
  ...
  cmd.Transaction = trans; 
  cmd.CommandText = "SELECT ID, NAME FROM STAFF WHERE JOB = 99";
  reader = cmd.ExecuteReader();    
  ...
}
catch (Exception ex)
{
  Console.WriteLine(ex.Message);
}

当 try 块中出现一个异常时，catch 块将捕获该异常。

ex.Message 包含异常的内容。含不兼容操作数的 SELECT 语句会生成以下异常：

ERROR [42818] [IBM][DB2/NT] SQL0401N  The data types of the operands for the 
operation "=" are not compatible.  SQLSTATE=42818

在清单 10 中的示例中，一个 SELECT 语句中的 WHERE 子句含有类型不兼容的操作数：STAFF 表的 JOB 列的数据类型是 VARCHAR，而不是 INTEGER。

                    
try
{
  ...
  cmd.Transaction = trans; 
  cmd.CommandText = "SELECT ID, NAME FROM STAFF WHERE JOB = 99";
  reader = cmd.ExecuteReader();    
  ...
}
catch (Exception ex)
{
  Console.WriteLine(ex.Message);
}

当 try 块中出现一个异常时，catch 块将捕获该异常。

ex.Message 包含异常的内容。含不兼容操作数的 SELECT 语句会生成以下异常：

ERROR [42818] [IBM][DB2/NT] SQL0401N  The data types of the operands for the 
operation "=" are not compatible.  SQLSTATE=42818
