I deleted a table in SQL Server Management Studio. And then I created a new table with the same name. But the error said that the table has already exists. I want a new completely table with the same name.
Edit: Added more answers after comment.
Are you removing the table from the database diagram or from the object explorer? If you are removing the table from your database diagram using Visual Database tools, it will still exist in the database.
From MSDN:
The table is removed from your diagram but it continues to exist in
the database.
OR,
Try going to Tools->Options->Designers and unchecking the box that says "Prevent saving changes that require table re-creation". Then try deleting and creating the database.
OR,
Delete the table. Close MS SQL Management Studio. Open MS SQL Management Studio again. Create table.
Old Answer
Are both statements
in the same batch? From the Microsoft support page for DROP TABLE:
DROP TABLE and CREATE TABLE should not be executed on the same table in the same batch. Otherwise an unexpected error may occur.
If this isn't the case I'll try to help otherwise. If I can't help otherwise I'll just delete this answer.
Basically you have one of it open in tab where you get new table...
Steps
Close all the tabs
When no tabs are open
Create you table
And there you are.... It worked for me rather than creating the whole database again.
Clock on Tools -> Options -> Designers -> UNcheck Prevent table changes from table re-creation check box.

I have created a MYSQL Database using XAMPP and PHPMyAdmin.
The Database has been firstly created using a MYSQL script which created and connected all tables.
In a second time I had to create and connect the table "Pietanza_nel_ordine". I created it with another SQL Query and then I connected the Foreign Keys using the tools provided by PHPMyAdmin.
This table works correctly even with Foreign Keys, however it is never shown in the Designer tool in PHPMyAdmin.
How can i get it to be shown?
Server version is 5.6.26, protocol 10.
PHPMyAdmin version is 4.4.14
I provide you with a few screenshot about my configurations:
Designer View:
Tables list:
Table Ordine:
Table Pietanza_nel_ordine:
I finally found out which was the problem:
The new table was added to my DB, but it wasn't added in designer schema.
I found out the option "Add tables from other databases" in the Designer View left dropdown, which allowed me to add my new Table in the Designer View (even if it was in the same Database).
I've successfully connected LibreOffice Base with MySQL data base server. I've tested if I modify my table from host (free hosting service on internet) then the changes are reflected when refreshing the table object in LO Base.
But my question is, can I modify DB table directly from LO Base? I guess that it's possible using sql queries from LO Base, but how? Please give me some insights or tutorials. Thanks.
The normal way to alter a table:
Tools -> SQL
Enter an ALTER TABLE command and press Execute button.
A way that works, even though it complains that no result set is returned:
Create a query in SQL view.
Enter ALTER TABLE command.
Click button in toolbar to mark it as Run SQL command directly. Or Edit -> Run SQL command directly.
Close the query and double-click to run it.
My guess is it could be done with a macro as well, similar to https://forum.openoffice.org/en/forum/viewtopic.php?f=5&t=75763 but using ALTER TABLE.
For more ideas see https://forum.openoffice.org/en/forum/viewtopic.php?f=61&t=37687.
EDIT:
Inserting new row data in a form is easier than altering the table. First, make sure this works:
Double-click on your table under Tables.
Insert -> Record, or enter data in the last new row.
If Insert -> Record is disabled, then you need to set up the table for editing. Make sure that your connection to the database allows editing. Also the table must have a primary key.
Once you can insert records in Table view, it's time to create the form:
Under Forms, Use Wizard to Create Form.
Select your table and press >> to include all fields.
Click Finish.
Now you should be able to open the form and enter data into the final new row.

I have this project that would require users to check in/out through a finger print reader ZK SF200.
The system that I am building needs to fetch new data that is added into this machine's database which unfortunately is a MS Access mdb file.
In my limited experience in MS Access databases, I managed to link this file to my MySql database table which allows me to manually do the insert from MS Access.
All I want to do now is to create some form of trigger that would add data to my MySql database when new rows are inserted into the MS Access table.
This problem would have been solved if the file type was .accdb because we can use After Insert events however it is an mbd type so those are not supported.
Any idea on how I can solve this matter ?
As a final note: I am willing to change DBMS in case MySql is the obstacle here. Would creating a linked server or doing sql server replication through mssql 2008 r2 work ?
EDIT: I need to insert data to MySql table because I have a trigger implemented there which does its side of logical manipulation of the data (ex: Increment the number of visits for the customer, check if customer subscription has expired or not and update the customer status accordingly)
Thank you.
Linking a table in MS-Access to the ODBC source is probably an answer for you. The table in MS-Access will be more like a view on the source table. Any DML operation (INSERT, UPDATE, DELETE) will be synced immediately with the source database. You will not need any trigger, which is not available in MS-Access (unless some VBA expert knows a solution).
The Linked table technology is default available for SQL-server, but since it uses ODBC I quess you can use it with MySQL too.
I am looking for a solution to the following:
Database: A
Table: InvoiceLines
Database: B
Table: MyLog
Every time lines are added to InvoiceLines in database A, I want to run a query that updates the table MyLog in database B. And I want it instantly.
Normally I would create a trigger in database A on INSERT in InvoiceLines. The problem is that database A belongs to a ERP program where I don't want to make any changes at all (updates, unknown functionality in 3-layer program, etc)
Any hints to help me in the right direction...?
You can use transactional replication to send changes from your table in database A to a copy in DB B, then create your triggers on the copy. It's not "instant," but it's usually considered "near real time."
You might be able to use DB mirroring to do this somehow, but you'd have to do some testing to see if you could get it to work right (maybe set up triggers in the mirror that don't exist in the original?)
One possible solution to replicate trigger's functionality without database update is to poll the table by an external application (i.e. java) which on finding new insert would fire required query.
In SQLServer2008, something similar can be done via C# assembly but again this needs to be installed which requires database update.
I am trying to change a design of a table in SQL Server 2008, but I am getting an error stating that I need to drop and recreate the table.How Can I Solve This Problem.
Saving Changes is Not Permitted.The
Changes you Have Made require the
following tables to be dropped and
re-created.you have either made
changes to a table that can't be
re-created or enabled the option
prevent saving changes that require
the table to be re-created.
Go to: Tools - Options - Designers - Table and Database Designers and de-select "Prevent saving changes that requiere table re-creation"
You can do most things with ALTER TABLE. Changing a datatype, nullability, adding/removing most constraints, adding/removing columns (ignoring order) should not require a table rebuild.
The GUI designer will ask for a table rebuild if you reorder columns, or add IDENTITY.
As Pcofre has said the answer is:
click Tools ---> Options ----> Designer ---->
on the right pane find the option meaning prevent the tables from being recreated
then Remove its tick
