Transact SQL :: Create Table Indexes In SSMS2012
May 26, 2015
I use Indexes Fundamentals of Microsoft SQL Server - Lesson 30: Indexes in the website of URL... to learn the basic things of Indexes. In my SQL Server 2012 Management Studio (SSMS2012), I executed the following code..
-- scFTX_CreateTableEmployees.sql
-- saved in C:/Documents/SQLServerIndexes_downloadCode
-- 26 May 2015 10:52 AM
USE ScottChangDB;
GO
CREATE TABLE Employees
[code]....
Where the SCHEMA and the index 'IX_Employees are located in the Object Explorer of the database "ScottChangDB" of my SSMS2012.

I'm working to improve performance on a database I've inherited, and there are several thousand indexes. I've got a list of ones which should definitely exist within the database, and I'm looking to strip out all the others and start fresh, though this list is still quite large (1000 or so).
Is there a way I can remove all the indexes that are not in my list without too much trouble? I.e. without having to manually go through them all individually. The list is currently in a csv file.
I'm looking to either automate the removal of indexes not in the list, or possibly to generate the Create statements for the indexes on the list and simply remove all indexes and then run these statements.
As an aside, when trying to list all indexes in the database, I've found various scripts to do this, but found they all seem to produce differing results. What is the best script to list all indexes?

I am studying indexes and keys. I have a table that has a fixed width of data to be loaded in the first column which is parsed in a view based on data types within the fixed width specifications.
Example column A:
(name phone house cost of house,zipcodecountystatecountry)
-a view will later split this large varchar string based
column b: is the source filename of the data load (varchar 256)
....
a. would there be a benefit of adding a clustered or nonclustered index (if so which/point in direction on why)
b. is there benefit of making one of these two columns a primary key (millions of records) or for adding a 3rd new column as a pk?
c. view: this parses the data in column a so it ends up looking more like "name phone house cost of house zipcode county state country" each having their own column.
-any pros/cons of adding indexes (if so which) to the view instead of the tables or both for once the data is parsed?

I create a script like below:
GO
SET ANSI_PADDING ON
GO
DECLARE
@ProjectID AS NVARCHAR(128),
@TableName AS NVARCHAR(128);
SET @ProjectID = N'EPA';
[code]....
The table created, but T-SQL created a table called @TableName.not like "EPA_SweetChargeCodeAssignees'
how to debug?

When I right click on a table and click Script Table as --> Create to --> it scripts out:
CREATE TABLE [dbo].[Test](
[FirstName] [varchar](50) NULL,
[LastName] [varchar](50) NULL,
[Address] [varchar](50() NULL
SET ANSI_PADDING OFF
ALTER TABLE [dbo].[Test] ADD [City] [varchar](50) NULL
Why is there an Alter table statement? I’m assuming this table was altered at some point but why is SQL not just doing a create table and how is it keeping track of these changes?

Im trying to insert the values from this query into a table, so I can later check the history of memory usage:
SELECT
[total_physical_memory_kb] / 1024 AS [Total_Physical_Memory_In_MB]
,[available_page_file_kb] / 1024 AS [Available_Physical_Memory_In_MB]
,[total_page_file_kb] / 1024 AS [Total_Page_File_In_MB]
,[available_page_file_kb] / 1024 AS [Available_Page_File_MB]
,[kernel_paged_pool_kb] / 1024 AS [Kernel_Paged_Pool_MB]
,[kernel_nonpaged_pool_kb] / 1024 AS [Kernel_Nonpaged_Pool_MB]
,[system_memory_state_desc] AS [System_Memory_State_Desc]
FROM [master].[sys].[dm_os_sys_memory]
What I'm missing is a way to insert the current timestamp every time I insert to the table.My plan is to use the insert into command.

I pulled some examples of using a subquery pivot to build a temp table, but cannot get it to work.
IF OBJECT_ID('tempdb..#Pyr') IS NOT NULL
DROP TABLE #Pyr
GO
SELECT
vst_int_id,
[4981] AS Primary_Ins,
[4978] AS Secondary_Ins,
[code]....
The problems I am having are with the integer data being used to create temp table fields. The bracketed numbers on line 7-10 give me an invalid column name error each. In the 'FOR', I get another error "Incorrect syntax near 'FOR'. Expecting '(', or '.'.". The first integer in the "IN" gives me an "Incorrect syntax near '[4981]'. Expecting '(' or SELECT". I will post the definitions from another effort below.
CREATE TABLE #Pyr
(
vst_int_idINTEGERNOT NULL,
--ivo_int_idINTEGERNOT NULL,
--cur_pln_int_idINTEGERNULL,
--pyr_seq_noINTEGERNULL,
[code]....

I have an Access app. that I am migrating the DB portion (queries, tables) to SQL server. I need to create a temp table that lasts as long as the user has the Access FE app. open. Idea is that the temp table stores the user's parameters (used for filtering data entry forms and report). The parameters allow the app. to only show the user his data (cannot view other users data). The SP shown below works OK, it creates a ##Temp table and updates it with the parameters sent by Access FE app. The issue I am having is that as soon as the SP finishes the ##Temp table is removed. I thought of using a regular table, but, I am currently testing this migration in my local SQL server instance, as soon as I move the database to production environment, then users will not be able to create tables as permissions are only read/write.
USE [Work_Allocation]

I 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.
CREATE NONCLUSTERED INDEX [R5IDX_TMP] ON #TEMPJOIN2
(
[PART] ASC,
[ORG] ASC,
[SPLRNAME] ASC,
[REPITEM] ASC,
[RFQ] ASC,

When creating the indexes on the table, SQL 7.0 also created some type of system indexes ( ex. _WA_Sys_curr_int_rate_2C88998B nonclustered, statistics, auto create located on PRIMARY, etc. ). I want to know how can I clear up these system indexes.

Hello,
A few months ago, the company I work for switched to SQL 7.0 from 6.5. All is running fine but recently I noticed that we have a ton of indexes on each table that start like this: _WA_SYS_....0B679CE2 (here are some specific examples: _WA_SYS_PRODUCT_LINE_0B679CE2, _WA_SYS_RMA_DISPOSITION_0B679CE2)
Did SQL 7.0 do this? If so why? What is it trying to do? Why doesn't it use current indexes (clustered and non-clustered)? Why don't they get Fragmented like User defined indexes? I have a lot of questions associated with this if someone can explain it.
Tech Net, MSDN, BOL and other manual resources don't mention anything about it. At least I haven't found anything on it and I have spent some time looking.
Please help if you can.
Troy

1)When we create Indexes, key columns are the columns that use in where clause and included columns are the columns that can be used in the select list and on join clause column.
2) I am thinking that we have to create new Index, only if we found at least 50 msec time save.

Hi,I have a new job. It needs to drop and re-create (by insert) a tableevery night. The table contains approximately 3,000,000 (and growing)records. The insert is fine, runs in 2 minutes. The problem is thatwhen I create the indexes on the table, it is taking 15-20 minutes.There is one clustered index and 11 non-clustered. This is a lookuptable that takes many different paremeters, so it really needs theindexes for the user interface to run efficiently. However, thedatabase owners aren't keen on a job taking 20 minutes to run everynight.Any ideas?

First, I'd like some help stablishing if it's a good idea or not what I'm thinking, and second is what would be the easyist way to achive the result.
Background. We have a multicompany ERP system (200GB, 200+ tables). All data tables have a companyid, counter1id, counter2id, fields. Each table has a primary clusterd index on these fields in that order. And also has multiple other indexes that usually include companyid filed first. ( Note we have 10 companies, ids are 1..10, companies 2 and 5 are the most active, inserts, selects ). MY GUESS IS THAT THIS IS VERY BAD HAVING COMPANYID FIRST. AM I CORRECT? LEADS TO AL LOT OF FRAGMENTATION? VERY BAD TO FIND DATA ON THE INDEXES?
I want to re-create all my indexes and have them counter2id, companyid, counter2id. ( counter1id is a counter for each company, and counter2id is a global counter like identity ) GOOD OR BAD IDEA?
Since I have hundreds of indexes what is the correct procedure? I was thinking on scripting the database, then dropping all indexes, then recreate clustered indexes, then recreate other indexes. Do I have to take care of anything else foreing relationships, etc.

Hi everyone,
I know that statistics called _WA_... are created on tables when auto create statistics is set on a database. Is this an indication that queries against the table would perform better if indexes were created on the columns in question? (The tables I'm interested in optimising are used equally for transactional querying and reporting)
Thanks for any replies!

I am new to writing SQL code and I read that you can use ALTER statements to create an index for a table. How would I go about doing that? Everything that I have tried in Query Analyzer comes up with an error.
Any help is appreciated.

I have a pretty large database that has tables that will contain millions of rows of records. I will predominantly be using Views just to select the data. (I will not be performing any updates or inserts). I propose creating indexes on the views. My question is - if I create indexes on my views, do I have to create them on the tables as well? Is it good practice to create indexes on tables by default even if I am not going to be performing select statements directly on my tables but via my indexed views? Any advice is appreciated.
Thanks
