Just throwing the question out there incase anyone has tried this. When you're using SQL Server Management Studio, you can right click on most objects and manually generate the create/drop/alter scripts.
Is it possible to generate the SQL scripts (or send the script text to a parameter) from within a stored procedure?
Thanks for any pointers!

I'm not aware of anything "built in" that would generate the create/alter/drop script for you, but the syntax of these commands is pretty straight forward.
For example:
IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[FSACTIONSET]') AND type in (N'U'))
DROP TABLE [dbo].[FSACTIONSET]
So you could build your own SPROC to generate the script syntax.
What are you trying to do ? Maybe there is a different way to attack your problem.

Right, that would be from a drop script.
I need to dynamically rebuild a large set of tables. There could be changes to the table on a daily basis, so I was hoping there would be a way to programmatically get at the create scripts and exec it as dynamic sql.

This tells me your design sucks. If you are changing table structure daily then there must be something disastrously wrong with your data design. I shudder to consider working in such an environment, it sounds like a nightmare.

I think I found a way to accomplish what I need. Thanks anyways.

Sure Ashfield (thanks for reminding me to do so).
I found this thread on another site. It got me pretty close to what I'm trying to do, just modifying to my needs.

i have the Following Query
select sa1 as[sa1],sa2 as [sa2],count(sa1) as [count] into #ttemp from EXP_REL_CLSH_CONT
group by sa1,sa2
having count(sa1)> 1
order by sa1,sa2
and my final query is this
select c.sa1,c.sa2,c.dur1,c.dur2 from EXP_REL_CLSH_CONT C
INNER JOIN #ttemp t
on c.sa1 = t.sa1
and c.sa2 = t.sa2
as you can see there are Duplicates in the sa1 and sa2. So i want to delete any of record but one of each. so that means at last there should be 5 Records.
that bring me these Duiplicate
sa1 sa2 Dur1 der2
============================
6 7 3 2
6 7 3 3
354 867 1 2
354 867 1 3
354 872 1 2
354 872 1 3
356 867 1 2
356 867 1 3
356 872 1 2
356 872 1 3
Thanks

Just 1 small doubt..
For every record, the
der2 field is different.
So how can u say that entire row is a duplicate(though the first 3 are same!)?
Please clarify this.. and what is the output u are expecting please put it clearly

i catch the Duplicate from two Records. i was able to do it like this
select sa1,sa2,count(sa1) from EXP_REL_CLSH_CONT
group by sa1,sa2
having count(sa1)> 1
order by sa1,sa2
SELECT ACTV as ACTV_ID--, count([VENU]) as , sum([stud])
into #temp
FROM [dbo].SOL_ACTV_VENU
group by ACTV
having count(venu) > 1
order by sum(stud)
and i was deleting my Duplicates like this
SET ROWCOUNT 1
DELETE EXP_REL_CLSH_CONT
from EXP_REL_CLSH_CONT C
INNER JOIN #ttemp t
on c.sa1 = t.sa1
and c.sa2 = t.sa2
SET ROWCOUNT 0
but now in SQL Rowcount = 1 will stop everytime a duplicates is deleted so that it cannot delete the second record. Its Good. But how can i make it to loop and skip one record and delete one in this approach ?

Try this
declare @t table(sal1 int,sal2 int,dur1 int,dur2 int)
insert into @t
select 6,7,3,2 union all select 6,7,3,3 union all
select 354,867,1,2 union all select 354,867,1,3 union all
select 354,872,1,2 union all select 354,872,1,3 union all
select 356,867,1,2 union all select 356,867,1,3 union all
select 356,872,1,2 union all select 356,872,1,3
select * from @t
I am taking this RecordSet
sal1 sal2 dur1 dur2
6 7 3 2
6 7 3 3
354 867 1 2
354 867 1 3
354 872 1 2
354 872 1 3
356 867 1 2
356 867 1 3
356 872 1 2
356 872 1 3
Since you want any one of the record set so I can use either
sal1 sal2 dur1 dur2
6 7 3 2
or
sal1 sal2 dur1 dur2
6 7 3 3
If this assumption of mine is correct, the here is the answer
select sal1,sal2,dur1,dur2 from(
select row_number() over(partition by sal1,sal2 order by sal1,sal2) rn, sal1,sal2,dur1,dur2 from @t) X
where rn = 1
Output:
sal1 sal2 dur1 dur2
6 7 3 2
354 867 1 2
354 872 1 2
356 867 1 2
356 872 1 2
Here I am considering only the first one for every duplicate entries
What next you can do is put this record set in some temp table , delete the original one and then insert this record back into the table.
Please let me know in case of any concern.
Note - This code will work for Sql server 2005+

User row_number partitioned over your key fields. This is a sample of a partition I use
ROW_NUMBER() OVER( PARTITION BY ProductID, SubProductID, IssueLabel, Maturity, CurrencyID, Exposure Order by Exposure) as RowNo
You need to include the ID field in the rest of the select and then delete any record where the RowNo > 1.

Hey everyone,
I'm using Oracle 10.2g with PL/SQL Developer 7.1 from Allround Automation and I want to list my tables one by one showing each detailing its fields.. Any simple way to do this??
Many thanks!

The only way I've done it in the past was write some PL/SQL code that would loop through tabels like: SELECT *
FROM ALL_TABLES
WHERE OWNER='myOwner
ORDER BY TABLE_NAME;

Use:
dbms_metadata.get_ddl(
object_type IN VARCHAR2,
name IN VARCHAR2,
schema IN VARCHAR2 DEFAULT NULL,
version IN VARCHAR2 DEFAULT 'COMPATIBLE',
model IN VARCHAR2 DEFAULT 'ORACLE',
transform IN VARCHAR2 DEFAULT 'DDL')
RETURN CLOB;
Example:
SELECT DBMS_METADATA.GET_DDL('TABLE',u.table_name)
FROM USER_TABLES u;
SELECT DBMS_METADATA.GET_DDL('INDEX',u.index_name)
FROM USER_INDEXES u;
Gives you all the tables and indexes for the logged in user.

Dear All,
I need your help and deal.
I'm using SQL Server 2005.
I want to select a number that nearby a number that i want.
Example:
30 is number i need. when select from table have some number equal it.
So i want a number is so near 30.
(12, 43, 31, 35) = 31
I am sorry if descipt not clear...
Thanks you for your help.
Best Regards,
Sovann

I dont get enough your question but I think you have to use BETWEEN in your select.
Example:
select * from yourtable where number between 29 and 31
This sttement will give you all records between value 29 and 31
It will be better if you explain more your question.

Thanks you Blue_boy
but i need only one number.
If that number do not have i need number that nearby it.
so how can i do ?

Well,I'm gonna ask you a question.
Case is: 1,29,30,32 and you want search the nearest number of 30? So, the nearest number is 29 and not 32, right?
What if you have case like this : 1,29,30,31? Which nearest number you need to get?
I think you have to write a function.

Try something like this:
DECLARE @Input int
SET @Input = 30
SELECT TOP 1 Col1 FROM Table1
WHERE Col1 = (SELECT MIN(ABS(Col1-@Input))+@Input FROM Table1)
OR Col1 = (SELECT @Input-MIN(ABS(Col1-@Input)) FROM Table1)
You may need to modify this query.

you can use the least-square approach, provided your numbers won't overflow when squared.
Example:
SELECT * FROM news1 ORDER BY (news_id-10)*(news_id-10)
would order the news items according to their distance of news_id value 10.
Then optionally pick the first one, or first few, with whatever your SQL environment needs for doing that
(often "TOP 1").

Awesome answer. Thanks for teaching me something new.
|
|
|
|
|
Better yet, this query works too:
SELECT * FROM news1 ORDER BY ABS(news_id-10)
|
|
|
|
|
of course it does, however using squares is a common technique to optimize a "cost function", say when you need to find a best match for several parameters, you do:
"... ORDERBY (var1-goal1)*(var1-goal1)+(var2-goal2)*(var2-goal2)...+(varN-goalN)*(varN-goalN)"
