'Declaration
 
Public Class DB2Error

public class DB2Error

Remarks

Use this class in conjunction with DB2ErrorCollection and DB2Exception to obtain a DB2 error information. This class is often used when the user executes DML array binding operations to obtain multiply error information.

Example

The following example generates DB2Exception, containing DB2ErrorCollection, due to inserting NULL values to NOT NULL columns. Then the example outputs DB2Error messages to console.

csharp

DB2Connection connection = new DB2Connection("User ID=db2admin;Password=db2admin;Server=db2;Database=SAMPLE");
connection.Open();
try {
        DB2Loader loader = new DB2Loader("DEPT", connection);
    loader.Open();
    loader.NextRow();
    loader["DEPTNO"] = 111;
    loader["DNAME"] = DBNull.Value; // database field cannot contain NULL values
    loader["LOC"] = "NEW YORK";
    loader.NextRow();
    loader["DEPTNO"] = 1;
    loader["DNAME"] = DBNull.Value; // database field cannot contain NULL values
    loader["LOC"] = "CHICAGO";
    loader.NextRow();
    loader["DEPTNO"] = 2;
    loader["DNAME"] = DBNull.Value; // database field cannot contain NULL values
    loader["LOC"] = "DALLAS";
    loader.Close();
}
catch (DB2Exception ex) {
    foreach (DB2Error error in ex.Errors) {
        Console.WriteLine("Message: " + error.Message + Environment.NewLine +
        "Native: " + error.NativeError.ToString() + Environment.NewLine +
        "Source: " + error.Source);
    }
}

Visual Basic

Dim connection As New DB2Connection("User ID=db2admin;Password=db2admin;Server=db2;Database=SAMPLE")
connection.Open()
Try
    Dim loader As New DB2Loader("DEPT", connection)
        loader.Open()
        loader.NextRow()
        loader("DEPTNO") = 111
        loader("DNAME") = DBNull.Value
        ' database field cannot contain NULL values
        loader("LOC") = "NEW YORK"
        loader.NextRow()
        loader("DEPTNO") = 1
        loader("DNAME") = DBNull.Value
        ' database field cannot contain NULL values
        loader("LOC") = "CHICAGO"
        loader.NextRow()
        loader("DEPTNO") = 2
        loader("DNAME") = DBNull.Value
        ' database field cannot contain NULL values
        loader("LOC") = "DALLAS"
        loader.Close()
Catch ex As DB2Exception
        For Each [error] As DB2Error In ex.Errors
                Console.WriteLine((("Message: " + [error].Message _
            + Environment.NewLine & "Native: " & [error].NativeError.ToString()) _
            + Environment.NewLine & "Source: ") + [error].Source)
        Next
End Try
