Diffrence Between Metadata Function And Transact-SQL
May 3, 2006
Dear all,
I want to know difference between Metadata function and Transact-SQL. When to use metadata function and when Transact-SQL like
To know database exists in SQL Server we have two options
through Transact-SQL
if not exists(select * from sysdatabases where name = 'Testing')
through Metadata function
if db_id('Testing') is not null
When should I use Transact-SQL and when metadata function.
Thanks,
Ashok

]First of all here is how i created my SQL database and established a connection in visual studio 05. I go into the server explorer and right click on the data connections node and and select "create new SQL database". A window then prompts me for a server name and data base name. Under server name I write "localhostSQLEXPRESS" and under data base name I put in whatever. This totally worked and the database was asigned the extension of .DBO
I can now insert, select and delete information with some simple ADO coding. The only problem is that using this method makes it seamingly impossible to FTP my database onto my host server. I am aware that I can create a data base in the APP folder by simply right clicking it and selecting " new database".
This would simplify the deploying process but I cant seem to establish a connection this way. Ive also noticed that when I use this method that it saves it as a .MDF instead of a .DBO. What is the difference? Why does my .DBO work but not my .MDF in my app folder? Im so confused over this issue that I am problably not even asking the right question. Bottom line is that I have a small web application with a .dbo database that works wonderfully in my isolated visual studio environment and I need a solution to deploy it on the world wide web. Please help with any information I would be very thankfull.

Hello all,
I am very astonished about the following (recplus has 4.2 Million records).
if I do this :
select sum (quantityInKg) from recplus where element_ID in (160,
161,
162,
164,
165,
166,
1756,
21707,
22052,
22063)
it takes about 2 seconds.
If I do this
select sum (quantityInKg) from recplus where element_ID in (select element_2_id from element_element where element_id = '159')
it takes 1 second. (select element_2_id from element_element where element_id = '159' gives the same list as in the previous query)
Now, why is there a speed diffrence, or better, why in this way? I would have expected it to be the othere way around !
Thanks for your feedbacks.

I found the 2 way to connect to database, in first one it uses Localhost but in another it uses Local.
Please tell me which is the better way and what is the difrence between both?

I have a query that worked fine on MSDE 2000. The query evaluates a date using which is written between ''. Ex '1-1-1970'
Now I detached and attached the database to a SQL Express instance and ran the query but it fails with the error:
The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.
When I remove '' around the dates in the query, all works fine. Is this because of a diffrence between MSDE 2000 and SQL Express?
By the way. I am using the sql.net library which 'creates the query for me'.

Hello All,
I need to determine that a piece of XML in a character field or variable is well-formed XML. I need to store this validation result (valid or not valid flag) in the table.
Does SQL provide some function for this? Is there any other way?
Thank you!

The input is like this : xxxxxxxx=yyyyy=key_id=12345xyxyx
I would like to use the right function and get 12345xyxyx alone. The function must search for the first '=' symbol from the right of the word and get the characters from the end till the '=' symbol.

Hi All,
Once again I find myself smacking my head into a wall (and it will probably be for naught). I'm trying to find a specific character in a string within a specific record. I've tried substring, but it's not quite getting me where I want to be. I even tried "nesting" the substring and got nowhere (but I could have had the syntax wrong when I nested it).
Here is a sample
Select substring(productimagefile, 20, 5)
from my table
What I need is something like this:
Select substring(findoneof(productimagefile, _r, 1), 1, 5)
from my table
Actually, on the start of the substring, I need it to be where it finds the _r, just not sure how to tell it that.
The replace function is the closest I've seen to what I need, but I don't want to replace it with anything, I just need to find it in the string.
So, if anyone has any ideas, I'd be grateful (and my head would stop hurting....)

I want the output to have sum of the duration ( from my function ), grouped by the state.So output should be :

I want to create a subset of a geography table. My intention is to select only a few cities with a where and after that select a percent of village for each of the cities. My query look like this:
SELECT TOP 160 [CodMunicipio] ,[NombreMunicipio] ,[CodProv],[Provincia] ,[COMUNIDAD AUTÓNOMA]
,[Longitud ETRS89/REGCAN95],[Latitud ETRS89/REGCAN95]
,[XUTM ETRS89/REGCAN95],[YUTM ETRS89/REGCAN95],[Bandera]
--INTO [PracticasSCD].DBO.DIMGEOGRAFIA
FROM [SportFunDW].[dbo].[DimGeografia2] TABLESAMPLE (3 PERCENT)
[Code] ....
I have tried with tablesample but it doesn´t return what I expect because I have many villages from one city (for example 15 % of it) and only 2 % of other. How can I achieve my goal?

I have an SP that is working, it creates a Union between 3 tables then creates a single table - I am using Visual studio Grid Control to view this by a browser, its working. at the bottom of the SP is a line of code that calls a function, the function queries a View. When I run the SP, SQL returns the data from the Union plus the data from the select statement on the Function. This all works but I can't get the data returned by the function query onto a browser.
I am doing it this was as the parameters in my SP are also used when calling the function, works really well. Is GTotal a return value?
Here is my function:
USE [LOGONs]
GO
/****** Object: UserDefinedFunction [dbo].[FX_AnnaulBudget1] Script Date: 23/09/2015 12:27:50 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
[Code] ....
...and here is my SP:
USE [LOGONs]
GO
/****** Object: StoredProcedure [dbo].[USP_AnnualBudget] Script Date: 23/09/2015 12:57:46 ******/
SET ANSI_NULLS ON

SET QUOTED_IDENTIFIER ON

I have a really basic question. The following SQL query works for me:
Select EnterUserID, Enterdate
from tblCsEventReminders
where EnterDate >= Convert(datetime, '2015-04-01')
I am essentially trying to write a query to count the number of user logins after a certain date, so I need to count 'EnterUserID' but I am having problems getting the count() function to work.

I have a query that uses the PIVOT function and works fine in SQL 2012. I've been asked to move the query to a database that has the compatibility level set to 80(SQL 2000). I receive an "Incorrect syntax near" error when I try to excute the query on the SQL 2000 database. I would like to duplicate the exiting PIVOT functionality in SQL 2000.The existing query retrieves employee names and the order that the employee should be displayed from a table. The names will appear on the report according to the order that is retrieved from the database. Also, the users have requested that only 5 names appear on each row of the report. This is why the PIVOT function was needed. Below is an example of how the existing query works.
Table
CREATE TABLE [dbo].[EmpGuest](
[Guest_ID] [int] NOT NULL,
[Guest_Name] [varchar](80) NULL,
[Display_Order] [int] NULL
) ON [PRIMARY]

SQL Sever 2012, I have a table where I store data related with a Log, the columns of the table are three, IDTable, DateLog and CountLog, the column CountLog is a cumulative value, each new rows can increment this value, my query will receive two parameters related with the Date, @dateFrom and @dateTo, with this information is necesary to get the diff between two months, for example:
CREATE TABLE MyTable
(
IDTable INT IDENTITY NOT NULL,
DateLog DATE NOT NULL,
CountLog INT NOT NULL
)
[code]....
In this case I need to apply a filter with the Dates:
@dateFrom ='2014-01-01',
@dateTo ='2014-04-28'
But according with this filter I need to limit the results only for this period between the date, but I need that the first month (January 2014) take the information of the max value from previous month even not included in the filter, in this case the results will be the next:
Id MonthYear Diff
1 Jan2014 5
2 Feb2014 3
3 March2014 0
4 April2014 5
With the results, for the first mont (January) is, according to the range of times, January is the lower limit,the last cumulative value of CountLog before the first month of the range was 2 (December 2013), the max value of the CountLog for this first month was 7, the diff is 7-2 equal to 5 , in the case of the next month (February) the max value of the CountLog was 10, the diff is 10 - 7 equal to 3 and this way.

I have a work database where I implemented a table-valued function. One colleague of mine reported to me that this function gave a Divide by Zero error when executed with some specific values given to its arguments (there are a 15 arguments). Then I started debugging, and I introduced some exit points to the function before its end in order to detect the point where the error appeared, since I don't have access to the database server and I cannot use the debugging tools from remote, due to the network configuration of my office. I can only do attempts on the code to try to find a solution.
Since I didn't manage to get rid of this error, I decided to make a silly and desperate attempt: I put a RETURN statement immediately after the BEGIN of the function body, with the idea that the function should not raie any error if it exit immediately after its beginning, despite the fact that this results in an empty table in return.
The result of my attempt is that the Divide by Zero error is still THERE (!), even if my function looks like
ALTER FUNCTION [dbo][<myFuncName>](...parameters...) RETURNS TABLE (...table definition...) AS BEGIN
RETURN
END
GO
How I can check it.

How can i subtract two columns:
I have table:
ID COL 1 COL 2

1 200.00 70.00
2 200.00 30.00
3 200.00 90.00
4 200.00 110.00Col1 - COL2
But to continue for each row and value is reduced by the previously value.
My output should be like as:
ID COL 1 COL 2 [COL3 AS RESULT]
-------------------------
1 200.00 70.00 130
2 200.00 30.00 100
3 200.00 90.00 10

Well adding it to a group by or function skews the result set. How to write this query so it displays as I need it to? This is what I have thus far, and it works as it should UNTIL I add in the line of
cast(cte.[C] As float)/cast(sum(cte.[C]) over() as float)*100 As [Rate1],
Presents the error of:
Msg 8120, Level 16, State 1, Line 35
Column 'cte.[C]' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
This is my full on query -- with 3 CTE's involved to get me the actual result set I am after.
;with cte as
(
select
[state],
case when exists (select 1 from table2 R where R.centername = d.centername) then 1 else 0 end as [L],
case when exists (select 1 from table3 C where C.centername = d.centername) then 1 else 0 end as [C]
