Thanks Paddy!

I am intersted in using the scripting feature as you mentioned to export code into sql text files and check into source control system. Could you let me know which menu do you mean please (some more steps)? I never did this before.

George

Right click on object in the object browser within management studio (can be SP, function, table), Script As, Create To, New file.

1.

I find I could only export one store procedure at one time? No quick export command from menu to export all store procedures from a database? Smile | :)

2.

I think half of my question is solved, i.e. how to get the text sql form of store procedure. My second half question is, how to sync code with source control system. I think the solution should be merging the code manually and paste the code into Management Studio, then execute alter store procedure to take effect the new changes? Is that working? Or you have better ideas?

George

re point 2:

Depends on your circumstances - if it's a standalone system and you only have one instance of it, then that sounds fine.

If you need to install this in a number of places, having a little installer application that runs through and executes each of the SQL files is probably a good idea - means you can always be sure that the latest of everything is on the machine.

Also, if you have the definitive version in source control, you can check that nobody's been f*cking around with it.

How about your answer to my question #1? Smile | :)

2.

I am interested in the installer solution. But how could I invoke SQL statements (e.g. the statements used to create table/store procedures) from an installer application? My confusion is the instlaler application should only be able to call binaries, but how to call sql statements (text, not binary)?

Any ideas to find where is the physical location of store procedures

All information concerning a stored procedure is located in system tables. These tables reside in the primary file group of the database. However, the physical location isn't normally relevant for these tables (unless you're interested in complex backup/restore scenarios etc.).

One place you can look at is sys.sql_modules. From that view you can see for example your current procedures and their implementation.

George_George wrote:
I have a source control system and I want to check-in the store procedure code

You can use Management Studio's ability to script a procedure. Using it, you'll get an initial version for your source control. After that, modify the script as you like and check-out/check-in when you make modifications. I'm not aware that Management Studio supports any source control system so you may have to do this using file system operations (meaning you checkout to a file and then open it in Management Studio etc)

And I also want to merge the store procedure code outside Management Studio using other diff tools and let Management Studio reflect the changes

As previously use whetever tools you need and open the result into Management Studio.

George_George wrote:
merge/change the code from outside, when I press refresh button in Management Studio, I can see the new merged code of store procedures

You first have to execute the script in order to get the procedure to the database. After that, you'll see the change.

Thanks Mika!

So many comprehensive comments.

Forgive me that I am a newbie and after reading and following your comments I have some further questions.

1.

"One place you can look at is sys.sql_modules." -- from Management Studio under System Database, I only see 4 database -- master, model, msdb and tempdb. Where could I find the sys.sql_modules as you mentioned?

2.

"You can use Management Studio's ability to script a procedure." -- good point to start! Could you let me know which menu do you mean please (some more steps)? I never did this before. Smile | :)

3.

"As previously use whetever tools you need and open the result into Management Studio."

"You first have to execute the script in order to get the procedure to the database. After that, you'll see the change."

Just confirm your points. My understanding is, I merge the code manually and past the code into Management Studio, then execute alter store procedure to take effect the new changes? Is that what you mean?

George

It depends on the version of your Management Studio, but most likely if you expand the following tree path, you'll find them: YourDatabase/Views/System Views. There's a bunch of views including sys.sql_modules.

Or another way is simply to execute a select statement:

select * from sys.sql_modules

George_George wrote:

Right click on the procedure and select Script Stored Procedure as/Create To/File... (or some other target). If you want to script everything in the database select the database, right click and Tasks/Generate Scripts...
Try to play around with the Management Studio. It has many helfpul features.

George_George wrote:

Exactly. That replaces the information in the system tables and then you can use your new version of the procedure.

Thanks Mika,

I have found the store procedures from sys.sql_modules! Cool! But I think using Script Stored Procedure as/Create To/File should be more convenient than using sys.sql_modules to achieve my goal of sync with source control system. Any comments or ideas? Smile | :)

George

Absolutely use scripting abilities provided by Management Studio.

The reason I explained the sys.sql_modules was to give you a basic understanding how SQL Server stores information about database objects in the system tables. This was based on your question "where is the physical location of stored procedures".

System tables are very handy in several situtations but in this particular case scripting using Management Studio is both easier and more reliable.

Have a look at my article here[^], it explains the System Management Object and gives you examples of how to generate scripts for all database objects - you may have to tweak it to do exactly what you want, but its a good starting point.

Right click your database > Tasks > Generate Scripts...

I assume you can follow a simple wizard, if not im sure you'll head back here asking something benign like "How to I click on OK to proceed?"

smarter ways to make a column value unique

George_George14-Jan-09 2:01

George_George

14-Jan-09 2:01

Hello everyone,

I have a table and a couple of columns in this table. For some specific column, it is not primary key, but I want to accept only unique value for this specific column for each row.

Currently, my naive solution is to use a store procedure to handle table insertion and if in the store procedure I find there is already a row whose existing value for the specific column is the same as the new column value of the new row to be inserted, I will return error from the store procedure and refuse to insert the whole new row.

Any other smarter ways?

thanks in advance,
George

SQL Server 2005 query execution time

hi,
Is there any way to find the execution time of a query? I simply don't want to perform time consuming queries,

My small attempt...

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
