SELECT Columns By Column-index NOT By Columnname!

Nov 20, 2005

Hello all,

how can I select one or more columns from a table by column-index and NOT by columnname?

e.g.:

SELECT tbl1.[1], tbl1.[2], tbl1.[3] FROM Orders AS tbl1

and NOT like this:

SELECT tbl1.OrderNo, tbl1.ProductNo, tbl1.Price FROM Orders AS tbl1

Is that possible in MS-SQL 2000?

Thanks a lot in advance

kind regards

Otto

SSIS - Failure Inserting Into The Read-only Column ColumnName

May 10, 2007

Hi folks, I have a little challenge for you, I hope :)

The short story is as follows: I have multiple rather well normalized tables, and a view which connect them all togheter. In one of the tables I have an xml column, which I in the view to varchar(4000), since SSIS doesn't like xml all that much. To make the view updateable I have an instead of trigger placed on it, which works quite perfectly from T-SQL. SSIS however, claims that I cannot insert to a read-only column. Does anyone have the slightest idea how I can get around this?

The only solution I can think of is having two columns for the XML data, one as varchar and the other as varchar, then having a trigger updating the xml column when the varchar is updated, but that would require recursive triggers, which I am not too happy with.

Cheers

SQL 2012 :: Include Columns In Index That Are In Where Clause / Select List And Join

Jun 2, 2014

Usually it is better to include the columns in the index that are in where clause, select list and join.I am thinking that the columns in the selected list is better to keep as index columns and the columns that are in the where clause is better to keep in key columns.Where do we use join column is it better to create as main key column or included column.

Multiple Columns Index/Key (does It Free Me From Creating A Single Column Indexes???)

Apr 12, 2007

I hope i'm in the right place, but thanks anyway....

Actually i have 2 questions (regarding sql-server Indices/Keys):



1) I have an index, which is consisted of 4 columns.

I've read elsewhere that this index functions (as well) as an index (single column

index) on the first column of this multi-column index.



Does this mean that if i'd like to have (in addition) Indices on all of the 4 columns

seperately i need to define only 3???



2) I have a unique key consisted of multiple columns.

I'd like to save an index to this combination of columns as well (to speed up

things in DB...).

Does the definition of a multiple-columns key free me from defining the multiple-

columns index???

can anyone explain the main diference between Keys and Indices???

Select A Value From Column Which Is Named Index

Dec 17, 2011

I want to Select a value from a Column which is named "Index" - and I don't want to change the name naturally. Is there a way to get a value without mentioning the Column name itself, rather the column number? "Incorrect syntax near 'Index'. If this is intended as a part of a table hint, A WITH keyword and parenthesis are now required. See SQL Server Books Online for proper syntax."

Occurs when I try to simply..
-> SELECT Index FROM Table WHERE Name like 'xyz' <-

How To Select All Columns Except One Column From A Table ?

Oct 6, 2006

Hi

I can't figure out how to do this and hope you guys can give me a hint....

I want to select all columns from a table except one column:

For example,


A table has 20 columns : {1,2,3.....20}

To select all of columns in a table, i could use
select * from table;

However, I want to select only column {1....19}

I do not want to type the column names in one by one in the SQL query,

is there a way to achieve this in a short form of Select?

Thanks,

How Dose It Matter For The Non-clustered Index Key Columns And Included Columns?

Apr 24, 2007

Hi, all experts here,

Thanks a lot for your kind attention.

As I am creating the non-clustered indexes for the tables, I dont quite understand how dose it really matter to put the columns in the index key columns or put them into the included columns of the index?

I am really confused about that and I am looking forward to hearing from you and thank you very much again for your advices and help.

With best regards,

Clustered Index On Client_ID+ORderNO+OrdersubNo, If I Create 3 Noncluster Index On Said Column Will It Imporve Performance

Dec 5, 2007



Dear All.

We had Teradata 4700 SMP. We have moved data from TD to MS_SQL SERVER 2003. records are 19.65 Millions.

table is >> Order_Dtl

Columns are:-

Client_ID varchar 10
Order_ID varchar 50
Order_Sub_ID decimal
.....
...
..
.
Pk is (ClientID+OrderId+OrderSubID)

Web Base application or PDA devices use to initiate the order from all over the country. The issue is this table is not Partioned but good HP with 30 GB RAM is installed. this is main table that receive 18,0000 hits or more. All brokers and users are using this table to see the status of their order.

The always search by OrderID, or ClientID or order_SubNo, or enter any two like (Client_ID+Order_Sub_ID) or any combination.

Query takes to much time when ever server receive more querys. some orther indexes are also created on the same table like (OrderDate, OrdCreate Date and Status)

My Question are:-


Q1. IF Person "A" query to DB on Client_ID, then what Index will use ? (If any one do Query on any two combination like Client_ID+Order_ID, So what index will be uesd.? How does MS-SQL SERVER deal with these kind of issues.?

Q2. If i create 3 more indexes on ClientID, ORderID and OrdersubID. will this improve the performance of query.if person "A" search record on orderNo so what index will be used. (Mind it their would be 3 seprate indexes for Each PK columns) and composite-Clustered index is also available.?

Q3. I want to check what indexes has been used? on what search?

Q4. How can i check what table was populated when, or last date of update (DML)?

My Limitation is i Dont Create a Partioned table. I dont have permission to do it.



In Teradata we had more than 4 tb record of CRM data with no issue. i am not new baby in db line but not expert in sql server 2003.


I am thank u to all who read or reply.

Index/performance Index For SELECT.... IN Statement

Sep 10, 2007



Hi All,

I 'm working to improve some sql performance.


One of the major syntax inside the SELECT statment is ..

WHERE FIELDA IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='A') AND
WHERE FIELDB IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='B') AND
WHERE FIELDC IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='C') AND
WHERE FIELDD IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='D') AND
WHERE FIELDE IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='E') AND
WHERE FIELDF IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='F')

(It's to compare the field content with some user input parameter inside a parameter table... )

I think properly is that the SELECT ... IN is causing much slowness in the sql statement. I have indexed FIELDA , FIELDB, FILEDC etc and those PARAVALUE and PARATYPE in the PARATABLE table. But perfromance is still slow and execution takes >20 seconds for 200000 rows of records.

Do any one know if still any chance to improvide the performance like this?

Much Thanks,

Andy

Transact SQL :: Select And Parse Json Data From 2 Columns Into Multiple Columns In A Table?

Apr 29, 2015

I have a business need to create a report by query data from a MS SQL 2008 database and display the result to the users on a web page. The report initially has 6 columns of data and 2 out of 6 have JSON data so the users request to have those 2 JSON columns parse into 15 additional columns (first JSON column has 8 key/value pairs and the second JSON column has 7 key/value pairs). Here what I have done so far:

I found a table value function (fnSplitJson2) from this link [URL]. Using this function I can parse a column of JSON data into a table. So when I use the function above against the first column (with JSON data) in my query (with CROSS APPLY) I got the right data back the but I got 8 additional rows of each of the row in my table. The reason for this side effect is because the function returned a table of 8 row (8 key/value pairs) for each json string data that it parsed.

1. First question: How do I modify my current query (see below) so that for each row in my table i got back one row with 19 columns.

SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B

If updated my query (see below) and call the function twice within the CROSS APPLY clause I got this error: "The multi-part identifier "A.ITEM6" could be be bound.

2. My second question: How to i get around this error?

SELECT A.ITEM1,A.ITEM2,A.ITEM3,A.ITEM4, B.*, C.*
FROM PRODUCT A
CROSS APPLY fnSplitJson2(A.ITEM5,NULL) B,  fnSplitJson2(A.ITEM6,NULL) C

I am using Microsoft SQL Server 2008 R2 version. Windows 7 desktop.

Order Of Columns For Index

Jun 19, 2013

I want to make an index with the following columns, actually together they constitute the PK of the table so the index is created automatically.

The question is witch sort order is the best to have if I want to fetch all rows for one date and one resource? And why?

WHERE Resource = "Car 1" AND Date = "2013-03-03"

Resource, Date, Time

Or

Date, Time, Resource

Below is an example with tree resources, but in reality there can be a lot more and also years of dates.

Car 1, 2013-03-03, 10.00

Car 1, 2013-03-03, 11.00

Car 1, 2013-03-03, 12.00

Car 1, 2013-03-04, 10.00

Get Columns In An Index And Their Order

May 20, 2008

Is there a dynamic management view or system procedure which I can use to find out what columns are in an index, what columns are as an INCLUDE in the index and whether or not the column(s) are ascending or descending. This is excluding the utilities I already know about below:

sys.indexes
sys.index_columns
sp_helpindex
dm_db_index_physical_stats
dm_db_index_operational_stats
I only ask because it is a pain to look through the sys.indexes and sys.index_columns tables every time I want to know about what columns are in the index created. I also know that scripting the index would give me the information I need but there must be a better way.

Many Thanks

How Many Included Index Columns Is Too Many?

Oct 4, 2007

I'm using sys.dm_db_missing_index_details to find missing indexes on a database that is currently in testing. After running a bunch of our reports, there are several suggested indexes on 3 or 4 columns that have 15 - 20 included columns. The included columns are mostly varchars ranging from 1 to 150 characters along with a couple of date columns. My index size on that table is already nearly twice the size of the data.

I don't think it's a good idea to add an index with that many columns, but the information I've read on included columns is very general. I'm wondering if there is something about them that I don't understand that would make this a good idea.

Hello everyone, I am new to ERWIN and I need helps from the experts outthere.We are using ERWin 4.1.2771 and have reversed engineered some MS SQLServer 2000 databases.The problem we are having is that we have a FK on a column to a tablewhere the PK of the referencing table is on another column (such as anidentity column). We have a unique index on the column in the PK tableand SQL Server allows you to build a FK reference even though thecolumn is not defined as the PK.Does anyone know how to create this type of FK within Erwin?Thank You
