Problem:

A few days ago, while migrating data from one database to another, I encountered an interesting problem which user faced a lot.

“I have two databases, I have to copy tables data from one database to another. My query is how can I copy table schema from one database to another with its schema and data”

In this blog, we will learn the easiest solution on how you can solve that query.

Solution

There are plenty of methods on how you can copy table schema and data from one database to another like Generate script wizard, Import/Export Wizard etc. But these methods are quite lengthy and requires users time.

The easiest solution to copy schema’s table from one database to another is to use SysTools SQL Server Database Migration Tool. You will able to migrate your tables schema by performing few steps.

How to Copy Table Schema and Data from One Database to Another?

Launch SysTools SQL Server Database Migration Tool.

Click Open and load your database MDF file.

Choose the Scan Modes accordingly and select the SQL Server version of your .mdf file.

Select the database table from the left side, which you want to migrate to another database.

Click on Export for migration process.

You will get two options for exporting. One is SQL Server Database and other is SQL Server Compatible Script. Choose it according to your need.

After filling the Server credentials, Select the destination database as ‘Export to Existing database’

Software will fetch the databases and let you select the database on which you want to move the selected table.

You will get two options to export. Select ‘With Schema & Data’. This option will copy schema & data of your selected table from one database and export it to another and click Export.

You will get popup of Export complete.

Conclusion

The blog covers the easiest workaround of mostly faced users query on how to copy schema & data from one database to another. You can also use Import/Export Wizard, Generate script wizard etc for object migration using SQL Server. But these methods has some limitations. In Import/Export wizard, the indexes and the key will not get transferred, you need to generate scripts for that. The export wizard fails if foreign keys connecting the tables together is not in a correct order. ‘Generate script’ method is used to generate a single script for tables schema, data, indexes and keys. But again, the limitation is this method doesn’t generate tables creation script in correct order.

So one can opt for SysTools SQL Database Migration Tool for fast migration of tables schema from one database to another.

Generate Database Scripts With Data In SQL Server

In this post we will discuss about how we can generate SQL Server scripts of our database with existing data, once we generate the script, the result will give you all the insert query with other queries so that the data also will get inserted in your new database. We are going to use the option ‘Schema and data’ in SQL server for this task. I hope the screen shots given will help you generate the script with insert queries.

Background

I was working with an article which has so many database transactions/actions. So I thought of attaching the database scripts with data also in the source code download section of the article, so that it may help user to insert the data in his/her database. That made me to write this article. I hope you will like this.

Steps To Generate Database Scripts With Data In SQL Server

Step 1

Right click on your database and select Task -> generate script.

Database_Scripts_With_Data_Select_Option

Step 2

Click next in the introduction screen.

Database_Scripts_With_Data_Inroduction

Step 3

Select the database object which you are all you need and then click next.

Database_Scripts_With_Data_Select_Database_Objects

Step 4

Now you will be shown a window which asks you about how your script should be published.

Database_Scripts_With_Data_Publish_Options

Click advanced in that window.

Step 5

Select ‘Schema and data’ from type of data to script option and then click OK.

Database_Scripts_With_Data_Advanced

Click next.

Step 6

Click finish, now check the script file, it must be having the insert queries too.

Database_Scripts_With_Data_Finish

Now what else is pending, go ahead and run your script.

Conclusion

Did I miss anything that you may think which is needed? Have you ever wanted to do this requirement? Could you find this post as useful? I hope you liked this article. Please share me your valuable suggestions and feedback.

Your turn. What do you think?

A blog isn’t a blog without comments, but do try to stay on topic. If you have a question unrelated to this post, you’re better off posting it on C# Corner, Code Project, Stack Overflow, Asp.Net Forum instead of commenting here.

Introduction

Hi All, How are you today? In this article we will see a solution for a fix that we usually encounter when you work in Microsoft SQL server. The error message will be “Saving changes is not permitted,The changes you have made require the following table to be dropped and re-created. You have either made changes to the table that can’t be re-created or enabled the option Prevent saving changes that require the table to be re-created.”. Let us see how we can solve this issue. I hope you will like it.

Background

As the error message says, it is because of you have enabled the option Prevent saving changes. Now we will see how we can disable that option in SQL Server Management Studio. Before going through the fix, we will see teh screenshot of the error.

Steps to follow

To fix this issue, you need to follow some certain steps. We will explain that here.

Step 1

Go to Tools menu and click on options.

Step 2

Now you can see a window is opened as follows. You can see some settings there. No need to change anything in that.

Step 3

Now go to Designers menu and click on “Table and Database designers”

Step 4

It is time for changing the settings. As you can see there is a check box which is captioned as “Prevent saving changes that requires table re-creation” . Just uncheck that and click OK.

That is all. Now if you try to save that table, you won’t be facing above mentioned issue. Have a happy table designing.

Conclusion

I hope you will like this article. Please share me your valuable thoughts and comments. Your feedback is always welcomed.

Thanks in advance. Happy coding!

SqlDateTime Overflow, Must be between Error

SibeeshVenu — Fri, 05 Jun 2015 07:16:12 +0000

Introduction

Hi All, I hope you are fine. We all are using SQL parameter in our application right?Yeah it is a good way to restrict the Injections are hijacks. But still if you pass those parameters in the right way, you will face lots of problems. In this article I am going to share you such an Issue. I hope you will like it.

Background

Morning I was working in a grid control which editable, and I selected a row to edit and started editing. In a date field I edited the date and clicked update button. I was expecting an output result as “Successfully updated”. But it didn’t happen. Instead it throws an error. “SqlDateTime Overflow, Must be between”

Using the code

To resolve this issue, first you must understand the root cause for this. I was passing the parameters as follows.

[csharp]
SqlParameter[] myParam = new SqlParameter[3];
myParam[0] = new SqlParameter("@name", myObject.name);
myParam[1] = new SqlParameter("@ValidFrom", myObject.hjcValidFrom);
myParam[2] = new SqlParameter("@ValidTo", myObject.hjcValidTo);
[/csharp]

When I run my application with above code, I got the following error.

So what is the fix/solution?

I changed the parameter as follows.

[csharp]
SqlParameter[] myParam = new SqlParameter[3];
myParam[0] = new SqlParameter("@name", myObject.name);
myParam[1] = new SqlParameter("@ValidFrom", myObject.hjcValidFrom.ToString("MM/dd/YYYY"));
myParam[2] = new SqlParameter("@ValidTo", myObject.hjcValidTo.ToString("MM/dd/YYYY"));
[/csharp]

That solved the issue. Simple right?

Some other case

There are dome other cases you may get this error if you use the codes as follows.
[csharp]
SqlParameter[] myParam = new SqlParameter[3];
DateTime myDate=new DateTime();
myParam[0] = new SqlParameter("@name", myObject.name);
myParam[1] = new SqlParameter("@ValidFrom", myDate);
myParam[2] = new SqlParameter("@ValidTo", myDate);
[/csharp]

What you have to do all to fix this issue is just take the now property value from your date time object and pass it your parameter.

[csharp]
SqlParameter[] myParam = new SqlParameter[3];
DateTime myDate = DateTime.Now;
myParam[0] = new SqlParameter("@name", myObject.name);
myParam[1] = new SqlParameter("@ValidFrom", myDate);
myParam[2] = new SqlParameter("@ValidTo", myDate);
[/csharp]

Conclusion

I hope you enjoyed reading and found this useful. Please share me your valuable feedback. For me it matters a lot.
