Transact SQL :: Query To Determine Overlapping Date Ranges (by Category)
May 12, 2015Given the data below, I have a couple needs:
1) Query to determine if any date ranges overlap (regardless of category, e.g., row ids 6 & 7 below)
2) Query to determine if any date ranges of the same category overlap
declare @t1 table (id int primary key, category int, start_date datetime, end_date datetime)
insert @t1 select 1, 1, '1/1/2015 12:00:00 AM', '1/15/2015 12:59:59 PM'
insert @t1 select 2, 1, '1/16/2015 12:00:00 AM', '1/31/2015 12:59:59 PM'
insert @t1 select 3, 1, '2/1/2015 12:00:00 AM', '2/15/2015 12:59:59 PM'

Transact SQL :: Create Index On Temp Table To Reduce Run Time Of Update Query
Apr 29, 2015I want to create index for hash table (#TEMPJOIN2) to reduce the update query run time. But I am getting "Warning!
The maximum key length is 900 bytes. The index 'R5IDX_TMP' has maximum length of 1013 bytes. For some combination of large values, the insert/update operation will fail". What is the right way to create index on temporary table.
Update query is running(without index) for 6 hours 30 minutes. My aim to reduce the run time by creating index.
And also I am not sure, whether creating index in more columns will create issue or not.
Attached the update query and index query.

How To Determine When To Re-Index Programmatically?
May 13, 2002Great Monday Morning to one and all,
Setup: SQL7 w/SP4 running on W2K Pro
Table in Question:
I have a system that processes inserts that originate from automatic data collection subsystems on manufacuturing cells. The system processes about 2500 records a day. The system is isolated with no ready support or attention. My goal is to automate any and every reasonable admin task. My present activity centers on re-indexing the main table (receives the data from the inserts, supplies the data for web based reporting).
The table - tb_production_log - receives inserts that are time stamped and bear a Machine_id. The table has a clustered index built on the Machine_id (int) and Date_time (time of data's acquisition). The table only receives Inserts, the records are never Updated. No inserts are out of time sequence (no older records ever have to be 'wedged' in amongst existing records). Ulitmately, the table is tested daily for records with age > 365 days. Such records are Deleted.
For the past week, I have been running a monitoring stored procedure on my test box to track the fragmentation of the tb_production_log table. It's based on DBCC SHOWCONTIG with some extra tests. After capturing the SHOWCONTIG data, the sp runs a test query against the table to emulate a typical User report. I track the time this query takes. The query covers records over the last 7 days. (approx. 17,500 records involved). In addition, I track the time it takes Inserts to run. Inserts are done in batches from an external app. I get a RecordsPerSecond data point for each batch.

How Can I Determine An Index Exists?
Dec 6, 1999Hi,
I'm trying to run a script to add an index to a table. The index might already exist so I want to drop it 1st if it does.
Is there an equivalent to the following that I use for tables for indexes?
if exists (select * from sysobjects where id = object_id('dbo.tblFred') and sysstat & 0xf = 3)
drop table dbo.tblFred
Thanks,
Martin
How Do You Determine An Index Is Unique From Sysindexes?
Mar 17, 2002I 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.

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.

Transact SQL :: DATEADD - Determine Prior Month
Jul 8, 2015My overall problem is to do some string manipulation and then DATEADD, but I still don't know why I getting what SQL is giving me.
To get the prior month, I use the following code;
SELECT
(
SELECT
RIGHT('00' + CAST(
CASE CAST(RIGHT(MAX(Eff_Period), 2) AS int) - 1
WHEN 0 THEN 12
ELSE CAST(RIGHT(MAX(Eff_Period), 2) AS int) - 1
END AS varchar(2)), 2)
)--, -- Month
--CAST(CAST(LEFT(MAX(Eff_Period), 4) AS int) - 1 AS varchar(4)) -- Year
FROM
Current_Membership;
This correctly gives me the proper month number for the prior month, in this case, '06' since the current month is '07.'
But, for debugging, I wanted to test to make sure it would properly adjust for January - '01' - by replacing MAX(Eff_Period) with '201501.'
It did. Worked fine. Then, to make really sure, I put in '201502.'
Instead of the single record of '01,' it shot out 177,209 rows of all '02's!
I put back in the MAX(Eff_Period) instead of the date string constant and, worked fine. Swapped back in the date string - boom! - 177,209 rows again.
Like I said, I can use DATEADD - Now I'm really confused. I changed the date string to '201501' just to verify before posting this, and it spit out 177,209 rows of '01's! So, to keep from altering things and to maintain the edit history, I started up another query and C&P'd everything to it. Then, on the original, I backed up to an earlier version, one that worked. That listing is the same as above, but the commented out comma in line 9 and the commented CAST in the line after it - to get the year - were uncommented.
Now, it works with both '201501' and '201502.' But, if I replace the comments, basically removing the CAST with the year, it slams back with 177,209 rows!

Transact SQL :: Determine When Database Was Backed Up Without Using MSDB Tables?
Apr 22, 2015I was wondering if there was another method to determine when a database was last backed up without using the backup history tables in msdb? whether using DBCC DBINFO, DBCC PAGE on a specific database page...etc.
Also, when restoring a database, is there a trace flag you can use to force restore details to be written to the error log?
Determine Date Database Was Last Used ?
Jun 15, 2006Hi There
I am trying to establish the date a database was last used.
At first i checked out sp_helpfile and sysfiles to see if there was a date last modified, i also tried using xp_cmdshell to check the date on the actual .mdf or .ldf on the o/s but if the file has not grown the date will be the create date.
I need to establish the date a database was last used, either the last time someone logged into it or the last time any sort of command was run against the database, i cannot use sysprocesses as there are no connections to the database, so i need to determine the last time there actually were any processes run against this database.
And i need to use tsql, checking audit logs etc is not viable, can anyone help ?
Thanx

Jan 27, 2006Hi Minor and inconsequential but sometimes you just gotta know: Is it possible to define a non-primary key index within a Create Table statement? I can create a constraint and a PK. I can create the table and then add the index. I just wondered if you can do it in one statement. e.g. I have: CREATE TABLE MyT (MyT_ID INT Identity(1, 1) CONSTRAINT MyT_PK PRIMARY KEY Clustered, MyT_Desc Char(40) NOT NULL CONSTRAINT MyT_idx1 UNIQUE NONCLUSTERED ON [DEFAULT])which creates a table with a PK and unique constraint. I would like (pseudo SQL):CREATE TABLE MyT (MyT_ID INT Identity(1, 1) CONSTRAINT MyT_PK PRIMARY KEY Clustered, MyT_Desc Char(40) NOT NULL CONSTRAINT MyT_idx1 UNIQUE INDEX NONCLUSTERED ON [DEFAULT]) No big deal - just curious :D Once I know I can stop scouring BOL for clues.

Transact SQL :: XML Not Using Proper Index?
Aug 26, 2015I have two xml queries that take long: the 1st query takes about 5 minutes (returns 700 rows) and the 2nd query takes about 10 minutes (returns 4 rows). The total rows in the table is about 2 million. There are three secondary indexes: Property, Value and Path in addition to the clustered index on CardID and Primary XML index. Here is the table definition:
CREATE TABLE [dbo].[Cards]
(
[CardId] [int] NOT NULL,
[Card] [xml] NOT NULL,
CONSTRAINT [PK_dbo_Cards_CardId] PRIMARY KEY CLUSTERED
([CardId] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
[code]...
Looking at the execution plan, the query uses the Primary XML Index even if I add any of the secondary xml indexes. My question is why does not the optimizer use the Property 2ndary index instead of the Primary XML Index? Microsoft recommends that creating a Property index for Value() method of the xml datatype would work to provide a performance benefit. What would be another alternative to make the query run faster?
