I would need to rewrite SQL code to determine that id is unique in the Customer table.
My two tables are:
CREATE TABLE CUSTOMER(
[CUSTNO] varchar(5) NOT NULL,
[ID] CHAR(9) NOT NULL,
[NAME] VARCHAR(128) NOT NULL,
[ADDRESS] VARCHAR(128) NOT NULL,
[DATEOFBIRTH] DATE NOT NULL,
[Code] ....
I need to write a script which will respond differently if a table's index forces uniqueness.
I am using SQL 7.0 and I am using the [sysindexes] table of my database to examine those indexes. I am using the [id] field from the [sysobjects] table for the table I am examining and I am using that [id] field to find like-valued [id] fields in the [sysindexes] table.
My problem is that I can't seem to determine, from an examination of the [sysindexes] table, whether, or not, an index is unique.
When adding an index, and checking the unique property of that index, the values that I get in the [status] field of [sysindexes] are different from the values which are supposed to show, at least according to the sysindexes (T-SQL) entry in SQL Server Books Online.
For instance, I have a table which combines two text fields which comprise the only key on a table. The unique and clustered boxes are checked in the index setup screen. When I look in the [sysindexes] table, the value in the [status] field is 2113554, which is not a value I see in the books online page. According to my books online page, a unique index should have a value of 2 in the [status] field and a clustered index should have a value of 16 in the [status] field. My assumption is that I should see a value of 18 in that [status] field, not 2113554.
I looks like the books online entry might be out-of-date because the field that is labeled [reserved1] in my books online page, is labeled [StatVersion] in my actual [sysindexes] table. That [StatVersion] field looks suspiciously like a Status Version field, possibly indicating that the Status field has undergone some sort of version revision?
Is anyone familiar with this stuff?
Thanks.

I have a customer table with the column "invoice_customer" (this is the customer_acccount of account where the bill is invoiced..)
so to get the invoice_customer address for the customer account - 13301
SELECT B1.address as InvoiceAddress
from CUSTOMER AS B1 , CUSTOMER AS E1
WHERE B1.customer_account = E1.invoice_customer and E1.customer_account = '13310'
i want to add the above InvoiceAddress to the query below:
select customer_account, order_no, date_req, del_address (InvoiceAddress)
from CUSTOMERS
INNER JOIN Orders on CUSTOMERS.customer_account = Orders.account
where status 'D'
How would I put the 2 togtheer...

I want to update the orders that has invoice number empty when doing a change in the customer table Nm.
My order table is named order and customer is named customer, they both have a column named CustId and Nm (name).
This works fine and shows in my case column Nm in 4 rows (for orders);
select
Order.Nm
from
Order
Join Customer
on Order.CustId=Customer.CustId
where
Order.CustId=@variable and InvoNo=''
But the update statement gets error;
Update
Order
set
Order.Nm=Customer.Nm
from
Order
inner join Customer
on
Order.CustId=Customer.CustId
where
Ord.CustId=@Variable and InvoNo=''
I use SQL 2008....
If I have a table structure similar to the following, how might I query it to obtain the Transaction ID, Transaction Date, and Customer Name for the most recent transaction per customer only:
TransactionTable:
TransactionID TransactionDate TransactionType CustomerName
1 10/1/07 1 Bob
2 8/30/07 2 Janet
3 9/17/07 1 Mike
4 9/25/07 1 Bob
The following query will return all records in the table other than Janets...not what I want:
SELECT Transaction ID, TransactionDate, CustomerName
FROM TransactionTable
WHERE TransactionType = 1
ORDER BY TransactionDate DESC
The following query will return all records in the table other than Janets again, because DISTINCT will use the combo of TransactionID, TransactionDate, and Customer name for uniqueness...not what I want:
SELECT DISTINCT Transaction ID, TransactionDate, CustomerName
FROM TransactionTable
WHERE TransactionType = 1
ORDER BY TransactionDate DESC
The results set I'm looking for would be the following, where only the most recent entry per customer with TransactionType 1 is returned (i.e. one record for Bob):
TransactionTable:
TransactionID TransactionDate CustomerName
1 10/1/07 Bob
3 9/17/07 Mike
I believe I need an appropriate subquery to yield the results I desire, but can't sort out what it is? I do not want to execute multiple queries but subqueries are fine. Unfortunately there's probably an easy answer that my brain is not currently generating. Any help would be appreciated.
Note, this is not a real table, but a sample to illustrate the concept for the query I need.
Thanks.

Above mentioned list is a snapshot of our customer master table ,which contain approximately 100 attributes related to a customer.
We are designing an application for banking sector (but NOT Core banking solution),for which we may need to capture variable number of addresses for bank's customer,i.e more then three types of addresses Fixed,Temporary and Communication addresses(which is generally the case with all banks).
A single address includes address1/address2/city/country/state/pincode fields.
In context of OLTP database,We have option to put multiple addresses in child table but that involves various joins at the time of data retrival and slow down the query.
As another option we can can create redundent addresses columns(address1/address2/city/country/state/pincode) in master table that will accumulate addresses if demand for more then three type addresses arises(although there is reasonable numer of extra addresses is expected, i.e 10)
Database is expected to serve the records of 25 million(approx) bank's customer,so does someone can suggest me how to maintan the balance between two approches.
We have a sales fact table that has sales by customers, products, date etc. and dimension tables such as customers, products etc.

Does anybody know of a way to determine the last date/time a table has been accessed (query/update)? I've done enough research to know that this isn't easy. However, perhaps somebody has figured out a way through some of the stats that SQL Server keeps to determine the last access of a table. I have recently been put on a team that had no DBA and has a number of databases out there. They would like to determine which databases are inactive and get rid of them. I am a developer and haven't had much SQL Server Administration experience. Any info will help greatly! Thanks!

Does anyone have a script that analyzes primary and foreign key relationships of tables and produces a suggested load order based upon dependancies?
Thanks,
Fred.
I have a requirement based on 2 parts to determine a row of data in a table through SSIS :
a. Work out the LEG_SEQ_NBR of the VESSEL, VOYAGE and LEG already stored in table1.
To do this join table1 and join table2 through BL_ID column.
b. Work out the 2ndVESSEL, 2ndVOYAGE and 2ndLEG.
Once we have identified the LEG_SEQ_NBR of the VESSEL,VOYAGE, LEG already stored in table1 we need to add '1' to this value and then find that LEQ_SEQ_NBR in table2.
The DDL of table1 and table2 along with the test data are as below:
CREATE TABLE [dbo].[table1](
[BL_ID] [decimal](10, 0) NOT NULL,
[VESSEL] [nvarchar](10) NULL,
[VOYAGE] [nvarchar](12) NULL,
[LEG] [nchar](3) NULL,
[Code] ....
For Example:
BLNO = 21 and BL_ID = 1
Current Vessel/Voyage/Leg in table1 = CEUR 032E E
LEG_SEQ_NBR of this Vessel/Voyage/Leg in table1 = '1'
Therefore if we add '1' to this value we'd be looking for LEG_SEQ_NBR '2' as the 2ndVESSEL,2ndVOYAGE,2ndLEG.
In this case that would = MARB 794S S
How this can be worked out through an SSIS job ?
How, other than by doing the addition on my own, can I detemrine the length of a row in a table?
TIA,

Good Morning
Is There anyway to determine the table you are referencing in a trigger's inserted / deleted tables?
i.e would this be possible
print @Table_Name + " was Updated"
Where @Table_Name is the table on which the trigger is created
(bad example I know but you get the idea)
Any input will be appreciated.
I need a SQL or TSQL command (not a stored procedure) that will determine if a table exists (TBL_PARAMETERS). The command needs to return a 1 if the table exists or 0 if it dose not exist.
Thanks!

code that I can use to determine if a certain table has been accessed in the past?
View 6 Replies View RelatedHi all,
I'm new to this whole trigger 'thing', so forgive me if this question has been asked and answered a few times already.
I'm in the process of writing a trigger that will send an e-mail to an application admin when any table within a given database is altered (IE, a column is added or deleted). I can get the e-mail to fire off when that happens without any issue, but I'd like to be able to let the admin know which table was tweaked and what new column was added.
Is this a relatively easy thing to do and I'm just not finding the right built-in variable name, or does something more need to be done?
Thanks,

Hi! I am new to SQL Server... looking for some veteran assistance.
"Data Integrity Report"
I need a Stored Procedure that takes a table name as a parameter and returns a cursor suitable as a data source for a pre-built Report Services report (I guess Report Services would call the SP?).
The cursor/report needs to have the following columns:
Ordinal_Position (I.E. Column number)
Column_Name
Number Of Blank Rows (how many missing values for this column in this table)
Difference (Between total rowcount and population of this column)
Data_Type
Column_Length (either Character_Maximum_Length or the numeric widths rolled up with COALESCE?)
Sample Data (The contents of the "first" row in the table, based on a TOP(1) and ORDER BY xxx)
The report should look like this (for a table with 100 rows):
Col Num Col Name # Blanks Difference Data Type Col Length Sample Data
1 Name 12 88 varchar 30 Sally Smith
2 Address 34 66 varchar 45 123 Main St Apt 45
3 Acct_ID 0 100 varchar 4 AB12345
Using the "Information_Schema.Columns" I can get everything I need except for #3 (blanks count) and #7 (Sample data).
Is it possible to do this as 1 query, with a CTE or APPLY or something, or do I need to do a table variable based on the Information_Schema and then use dynamic SQL and row-by-row COUNT(*) for each column? And the same for the Sample Data.
Sorry for the long post, and thanks in advance!

I have a transaction table having about 40 crore rows in source. It don't have timestamp and unique key columns. It have only Bill_month and Bill_Year columns. Actually for loading this table into staging I have added a new datetime column by adding default bill_date as 01. Then
* First we delete last 3 month data from staging tables.
* Get last 3 months data from source table.
* Load that 3 months data from source to staging table.
We do this because we only get update for last three months data. Now I have to include this transaction table as Fact table in DW. What will be the best practice for loading the fact table by picking data form staging table. Also we have to look up with dimensions for Foreign Keys.
* Should I implement the same method of deleting last 3 months records and loading them again.

I'm building a web site. there is a database.
I've set a primary key and unique of a field.also I set it to auto numbering.
Everytime I insert a record , that field will increase 1 (type bigint , start from 1).
After lots time of inserting record , the id going to be larger number.. I wondering how can I reset that to zero?
I am working on some tables and would like to know which is best way to go when deciding what Type to use for Unique ID in my tables please. Int Or uniqueIdentifier? Or is it all the same??

Hello,
I would like to store some frequently asked questions in a database.
As those questions/answers could be translated in several languages, I was thinking of using two tables :
The first table would contain a unique field : the key wich is an id for each faq.
The second table would contain those fields :
FAQ_ID : foreign key
LANG : language
QUESTION : the question translated in the good language.
ANSWER : the answer translated in the good language.
What I find embarrassing, is that first table just contains a unique field : the id. But it allows :
- to have a table in which a line correspond to an object. It is convenient for object relational mapping.
- it is more evolutionary. If, in the future, I have to add some statistics that concerns a faq, I will have the possibility to store them in the first table, avoiding in this way to duplicate data.
But, one more time, I find a bit embarrassing having a table with a unique field...
What is your opinion about that ?
Thank you in advance for any suggestion.

View 8 Replies View RelatedI have a stored procedure that appends data from a temp table to a destination table. The procedure is called from an aspx web page. The destination table has an index on certain fields so as to not allow duplicates.
The issue I'm having is if the imported data contains some records that are unique and some that would be duplicate, the procedure stops and no records are appended. How can I have this procedure complete it's run, passing over the duplicates and appending the unique records? Since the data is in a temp table (which gets deleted after each append) should I run some sort of 'find duplicates' query, and delete the duplicates from the temp table first, then append to the destination table?
Thanks in advance.SMc
I need to to have a table that has a counter field (used to generate an id code for a record). This is not the primary id for the field but just a counter to label a record in another table, similar to a registration code for an event. This is a sequential counter that will start 1 and go up on each new record inserted into other tables. What I want to do is be able to query this counter table to get the next valid number and increment the count for the next time. This is a multi user web app so needs to prevent duplicate use of same number.How best should this be handled? A transaction to query and update the field?
