We are using Sybase 8 and Sybase 16 databases in our current project. I have a requirement where I need to script the a complete Sybase database(with some built-in data in certain tables) with Sybase scripting tools. For example, if I run a Sybase script, it would create a Sybase database for me. I tried using the combination of Dbunload (to create a dump), dbinit (to create a new db) and dbisql (to add data to database) commands but am not able to get at it. Require help regarding this from any Sybase db administrator in this forum.Thanks.
If you want to use a complete tool to generate the DDLs then you can use PowerDesigner for example.
If you want to write your own scripts in T-SQL or Watcom SQL what create the DDL scripts then you can also do this. All information about table schema is available in system tables. The full description of columns is also available in the documentation of SQL Anywhere.

I want to dump one SQL Server database - get all SQL code necessary to create a similar database. I have full online rights to DatabaseA, I can feed it with SQL and get the results back in rows in a table.
I do not have the possibility to use Enterprise Manager, any applications, utilities or the like. I can only feed it with pure SQL.
What I am after is SQL code, like CREATE TABLE and so on. So that I just can paste this into a query and voila - tables, procedures, functions are created in DatabaseB.
I will not copy the data.
This partly does what I want, it gives me procedures and functions:
Select object_Name(object_ID),definition from sys.SQL_Modules
But not for tables.
You can use the command line or you can create a stored procedure to create a back up, then use that backup to create a new database. I have used the command line often. Here is a previous Stack question that has a command line example and a link to a stored procedure example.
You can generate scripts in SQL Server Management Studio for an entire database or specific database objects.
To do this, right click the database then select Tasks then select Generate Scripts.
It will then open a wizard which will give you the option to choose to script the full database or just specific database objects.
My primary reason for this is to keep track of database schema changes for my application. In SQL Server Management Studio I am able to generate a create script which creates the database but it doesn't contain any test data. Ideally when the script is run it should DROP the existing database (assuming it already exists) and then recreating it using this new script containing schema changes and test data from my development machine.
So how can I generate a script that will create a database with all the tables, stored procs, triggers, views, test data, etc?
I've tried using the import/export functionality but that's no good because it doesn't seem to copy over stored procedures. Plus it would be nice to have a script so I can track changes to the schema using mercurial.
I am using SQL Server Express 2008 R2 along with SQL Server Management Studio.
You didn't mention which version of SQL Server, but in SQL 2008 this is very easy
SQL 2008
Expand Databases
Right Click Database
Choose Tasks > Generate Scripts
Generate and
Publish Dialog will open Choose your
objects (i.e. Tables, procs, etc)
Click Next On the Set Scripting
Options choose Advanced Options Under

Data Close Advanced Window Choose to
save to file.
I wrote an open source command line utility named SchemaZen that does this. It's much faster than scripting from management studio and it's output is more version control friendly. It supports scripting both schema and data.
To generate scripts run:
schemazen.exe script --server localhost --database db --scriptDir c:\somedir
Then to recreate the database from scripts run:
schemazen.exe create --server localhost --database db --scriptDir c:\somedir
Try Microsoft SQL Server Database Publishing Wizard. This is a powerful flexible tool for scripting schema / data rom SQL Server.
Personally I use Microsoft Visual Studio 2010 Database Project with a Source Control Repository (SVN) to track changes to the schema.
Watch out for difference in database collation. If you develop on a database with a case insensitive collation and try and run the SSMS generated scripts against as database with a case sensitive collation then errors in case will break the scripts.
Usually i make backups fom a database before start a new development on it.
the best way is restore the backup when needed, i don't know how to get it by the script way!
I'm wanting to take data from a SQL Server table and populate a Oracle table. Right now, my solution is to dump the data into a Excel table, write a macro to create a sql file that I can load into Oracle. The problem with this is I want to automate this process and I'm not sure I can automate this.
Is there an easy way to automate populating a Oracle table with data from a SQL Server table?
Thanks in advance
I suppose it depends on your definition of "easy".
The most robust approach would be to either use heterogeneous connectivity in Oracle to create a database link to the SQL Server database and then pull the data from SQL Server or to create a linked server in SQL Server that connects to Oracle and then push the data from SQL Server to Oracle.
Yes. Take a look at MS SQL's SSIS which stands for SQL Server Integration Services. SSIS allows all sorts of advanced capabilities, including automated with Sql Server Jobs, for moving data between disparate data sources. In your case, connecting to Oracle can be achieved a variety of ways.
There are three ways to automate this:
1) You can do as Paul suggested and created an SSIS package that will do this and it can be scheduled via SQL Agent,
2) If you don't want to deal with SSIS, you can download the free SQL# (SQLsharp) CLR Library from http://www.SQLsharp.com/ and use the DB_BulkCopy Stored Procedure to do this in a T-SQL Stored Proc which can also be scheduled via SQL Agent. [note: I am the author of SQL#]
3) You can also set up a Linked Server from SQL Server to Oracle, but this has the draw-back of being a potential security hole. Of course, you could use an Oracle Login that only has write-access to that single table (or something similar to that).
There are lots and lots of ways to do it. Which you choose depends on your requirements.
Using Excel is fine if it's a one time thing.
If it's a once-in-a-while thing, then you could write a simple .NET app that uses a single DataSet and multiple DataAdapters to do the data dump. C# code example here.
if it's a regular thing, then you could put the above in a Schtasks task, or you could use SSIS. I think SSIS is an extra-cost option.
if the requirement is for "online access", then a linked database is probably appropriate.
I would like to copy a table from one database to another. I know you can easily do the following if the databases are on the same SQL Server.
SELECT * INTO NewTable FROM existingdb.dbo.existingtable;
Is there any easy way to do this if the databases are on two different SQL Servers, without having to loop through every record in the original table and insert it into the new table?
Also, this needs to be done in code, outside of SQL Server Management Studio.
Yes. add a linked server entry, and use select into using the four part db object naming convention.
Example:
SELECT * INTO targetTable
FROM [sourceserver].[sourcedatabase].[dbo].[sourceTable]
If it’s only copying tables then linked servers will work fine or creating scripts but if secondary table already contains some data then I’d suggest using some third party comparison tool.
I’m using Apex Diff but there are also a lot of other tools out there such as those from Red Gate or Dev Art...
Third party tools are not necessary of course and you can do everything natively it’s just more convenient. Even if you’re on a tight budget you can use these in trial mode to get things done….
Here is a good thread on similar topic with a lot more examples on how to do this in pure sql.
SQL Server(2012) provides another way to generate script for the SQL Server databases with its objects and data. This script can be used to copy the tables’ schema and data from the source database to the destination one in our case.
Using the SQL Server Management Studio, right-click on the source database from the object explorer, then from Tasks choose Generate Scripts.
In the Choose objects window, choose Select Specific Database Objects to specify the tables that you will generate script for, then choose the tables by ticking beside each one of it. Click Next.
In the Set Scripting Options window, specify the path where you will save the generated script file, and click Advanced.
From the appeared Advanced Scripting Options window, specify Schema and Data as Types of Data to Script. You can decide from here if you want to script the indexes and keys in your tables. Click OK.
Getting back to the Advanced Scripting Options window, click Next.
Review the Summary window and click Next.
You can monitor the progress from the Save or Publish Scripts window. If there is no error click Finish and you will find the script file in the specified path.
SQL Scripting method is useful to generate one single script for the tables’ schema and data, including the indexes and keys. But again this method doesn’t generate the tables’ creation script in the correct order if there are relations between the tables.
Microsoft SQL Server Database Publishing Wizard will generate all the necessary insert statements, and optionally schema information as well if you need that:
http://www.microsoft.com/downloads/details.aspx?familyid=56E5B1C5-BF17-42E0-A410-371A838E570A
Generate the scripts?
Generate a script to create the table then generate a script to insert the data.
check-out SP_ Genereate_Inserts for generating the data insert script.
Create the database, with Script Database as... CREATE To
Within SSMS on the source server, use the export wizard with the destination server database as the destination.
Source instance > YourDatabase > Tasks > Export data
Data Soure = SQL Server Native Client
Validate/enter Server & Database
Destination = SQL Server Native Client
Validate/enter Server & Database
Follow through wizard
SQL Server 2005. Is there a sql query that will return a text field containing the same type of schema info as you would find in doing a right click table -> Script Table As -> Create To (or Alter To) from SQL Server Management Studio ?
I'm looking for a single/flat format that describes the entire table, including constraints, indices, etc.
I am aware of:
sp_help table_name
but that doesn't provide the single flat format I'm looking for. Ideally it would be in a scriptable format, such as the AlterTo result that could be executed against the server.
This is for a scheduled process that documents table schemas on a nightly basis for checking in to version control (SVN).
Not really. A table def is a collection of columns, constraints etc.
There is an SVN plugin that may help called ScriptDB4SVN. I've not used it personally, I'm going on hearsay.
Was searching the 'net again for an answer to this, and came across this SO question. It doesn't accurately capture all the same data as SQL Management Studios Create-to, but enough for my purposes (scripting the database structure for version control purposes).
There is no such command in SQL Server. This is primarily because the Scripting facilitiy is actually in SMO and not in SQL Server itself. There are a number of free console command-line tools that can do it that you could call via xp_CmdShell.
However, if you really want to do this from T-SQL, then you will need a script or stored procedure that enumerates all of the tables attributes, columns, column datatypes, defaults, nullabilty, etc. etc. and then reassembles it into a CREATE TABLE script. This is a Huge task. That's the bad news. The good news is that someone (Lowell Izaguirre) has already done this and posted it in this article (http://www.sqlservercentral.com/scripts/Miscellaneous/30730/) at SQLServerCentral.Com.
Enjoy.
Not really - you can either use C# (or VB.NET) and SMO (SQL Management Objects) to script out your database objects (tables and all), or you can use SQL to get the list of columns for a table:
SELECT * FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'Your Table Name here'
But I don't know of any easy way in SQL itself to create Create/Alter scripts for database objects, sorry.
