Please suggest what could be the reason and if is Deployed in the Testing environment. How we can fix it. In Snapshot we can easily check that duplicate column has been created in Migration and snapshot, however in entity i have placed the column name only once

thanks Ashish

Hi @mahendra

I couldn't find any related issue in npgsql GitHub repository. You can try to upgrade npgsql version to latest possible version. Then, you can modify this migration manually to remove the duplicate field generation.

I think, if you try to apply this migration, it will fail since it will not be able to create the same field twice.

Hi ismcagdas ,

Still Column with same column is Created, we are not getting any issue. I think remove column from the migration is not a good idea.

Thanks Ashish

The source of the error you mentioned is migrations. I removed your migrations and generate a fresh one. It all worked. I did research within migrations but could not see the exact source of the error.

Hi musa.demir,

Thanks for your response.

**Have you removed all the migration and generated the new Migration ? **

Note : We are facing this issue only for the foregin key column. I tried again and facing same issue.

Table Class where added the column OEEnumNotificationStatusId

[Table("OESolutionProcessLink")]
public class OESolutionProcessLink : Entity
{

    public virtual int OESolutionId { get; set; }

    [ForeignKey("OESolutionId")]
    public OESolution OESolutionFk { get; set; }

    public virtual int OEProcessId { get; set; }

    [ForeignKey("OEProcessId")]
    public OEProcess OEProcessFk { get; set; }

    public virtual int? OEEnumNotificationStatusId { get; set; }

    [ForeignKey("OEEnumNotificationStatusId")]
    public OEEnumMaster OEEnumNotificationStatusFk { get; set; } 

}

Following Migration is Generated When i Change the Encoding to ANSI, i noticed that there are some special characters in the migration for the column OEEnumNotificationStatusId namespace OneEnterprise.iHUB.Migrations { public partial class addedIssueColumn : Migration { protected override void Up(MigrationBuilder migrationBuilder) { migrationBuilder.AddColumn<int>( name: "OEEnumNotificationStatusId", table: "OESolutionProcessLink", nullable: true);

        migrationBuilder.AddColumn&lt;int&gt;(
            name: "OEEnumNotificationStatusâ€‹Idâ€‹",
            table: "OESolutionProcessLink",
            nullable: true);

        migrationBuilder.CreateIndex(
            name: "IX_OESolutionProcessLink_OEEnumNotificationStatusâ€‹Idâ€‹",
            table: "OESolutionProcessLink",
            column: "OEEnumNotificationStatusâ€‹Idâ€‹");

        migrationBuilder.AddForeignKey(
            name: "FK_OESolutionProcessLink_OEEnumMaster_OEEnumNotificationStatus~",
            table: "OESolutionProcessLink",
            column: "OEEnumNotificationStatusâ€‹Idâ€‹",
            principalTable: "OEEnumMaster",
            principalColumn: "Id",
            onDelete: ReferentialAction.Restrict);
    }

    protected override void Down(MigrationBuilder migrationBuilder)
    {
        migrationBuilder.DropForeignKey(
            name: "FK_OESolutionProcessLink_OEEnumMaster_OEEnumNotificationStatus~",
            table: "OESolutionProcessLink");

        migrationBuilder.DropIndex(
            name: "IX_OESolutionProcessLink_OEEnumNotificationStatusâ€‹Idâ€‹",
            table: "OESolutionProcessLink");

        migrationBuilder.DropColumn(
            name: "OEEnumNotificationStatusId",
            table: "OESolutionProcessLink");

        migrationBuilder.DropColumn(
            name: "OEEnumNotificationStatusâ€‹Idâ€‹",
            table: "OESolutionProcessLink");
    }
}

}

Hi @mahendra Yes, I have removed all migrations and created a fresh one. That also solved the problem. You can also check https://support.aspnetzero.com/QA/Questions/10155/Duplicate-Column-with-same-name-is-getting-Creating-when-using-Code-First-Approach-postgres#answer-5eac3cfb-5f57-c467-8e2b-39fb32833e3b. The problem seems to be in npgsql.
