Hi,
Imagine a group of tables headed by Columns: "Day","Customer",and "Town". With One C.Index already built based on "Day" and "Customer". Most queries have only these 2 Columns in their WHERE Clauses.
Now if a new group of Queries are to be run where the WHERE Clause will take "Day" and "Town" but not "Customer".
Question:
Is it better to a) add a New - 2nd C.Index to each table based on "Day" and "Town" or b) to remove it and Create a New (Only one) Cluster Index based on 3 Columns: "Day","Customer","Town" ?
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?
During the installation of Adding node to a SQL Server failover cluster(On passive node) getting error like.. The MOF compiler could not connect with the WMI server. This is either because of a semantic error such as an incompatibility with the existing WMI repository or an actual error such as the failure of the WMI server to start.We run the below commands but didn’t get any resolution & got the same above error .
1<sup>st</sup> Method…
1. Open console command (Run->CMD with administrator privileges).
2. net stop winmgmt
3. Rename folder %windir%System32WbemRepository to other one, for backup purposes (for example _Repository).
I am in the process of moving databases from a SQL 2005 Standard version to a 2-node 2014 cluster.All of my 2005 databases back up successfully.They all restore without issue except for one database that has a full text catalog. I get this message
Msg 7610, Level 16, State 1, Line 2 Access is denied to "fileStoragedataMSSQLSERVERFullTextCatalog", or the path is invalid. Msg 3156, Level 16, State 50, Line 2 File 'sysft_FTCatalog' cannot be restored to 'fileStoragedataMSSQLSERVERFullTextCatalog'. Use WITH MOVE to identify a valid location for the file. Msg 3119, Level 16, State 1, Line 2 Problems were identified while planning for the RESTORE statement. Previous messages provide details. Msg 3013, Level 16, State 1, Line 2 RESTORE DATABASE is terminating abnormally.
[code]....
I went as far as giving the folder full access to everyone temporarily and received the same error.
Can I build a cluster by adding the cluster service, then the SQL instances, then add the other nodes and their passive SQL instances?I would lean to building the cluster first, the add the SQL instances.
I have following script which i am planning to run to drop all non-clustered primary keys on a database and then created as clustered. I am using someone else's script so don't know how to modify this. Some of primary key columns are used in references in other tables.
is there anyway i can drop the existing primary keys and using their original script then create again as clustered including restoring all foreign and reference keys and unique or no unique.
DECLARE @table NVARCHAR(512), @tablename NVARCHAR(512), @sql NVARCHAR(MAX), @sql2 NVARCHAR(MAX), @sql3 NVARCHAR(MAX), @column NVARCHAR(MAX); DECLARE @indexname NVARCHAR(512); SELECT name As 'Table'
We are planning to change all IPs of PRODUCTION Failover Cluster Setup. In my cluster setup ... we have 2 Physical Nodes with windows-2008, Roles are MSDTC and SQL-2008R2.
IP change for:
1. Both Nodes(Physical) 2. MSDTC 3. SQL Server 4. windows Cluster
So Almost... All IPs are going to change.
Im DBA here, I need to take care of SQL cluster and MSDTC. But I haven't performed this activity before.So I'm worrying about Impacts and consequences of this change. steps how should I perform this activity.
We have many tables which have cluster index on column with datatype 'Char(200)'. Does anyone have script to change cluster index to noncluster for all user tables which have clustered index on a column with 'char(200)' datatype.
So I'm reading http://www.sql-server-performance.com/tips/clustered_indexes_p2.aspx and I come across this: When selecting a column to base your clustered index on, try to avoid columns that are frequently updated. Every time that a column used for a clustered index is modified, all of the non-clustered indexes must also be updated, creating additional overhead. [6.5, 7.0, 2000, 2005] Updated 3-5-2004 Does this mean if I have say a table called Item with a clustered index on a column in it called itemaddeddate, and several non-clustered indexes associated with that table, that if a record gets modified and it's itemaddeddate value changes, that ALL my indexes on that table will get rebuilt? Or is it referring to the table structure changing? If so does this "pseudocode" example also cause this to occur: sqlstring="select * from item where itemid=12345" rs.open sqlstring, etc, etc, etc rs.Fields("ItemName")="My New Item Name" rs.Fields("ItemPrice")=1.00 rs.Update Note I didn't explicitly change the value of rs.fields("ItemAddedDate")...does rs.Fields("ItemAddedDate")=rs.Fields("ItemAddedDate") occur implicitly, which would force the rebuild of all the non-clustered indexes?
I am trying to upgrade a SQL Server 6.5(Cluster) to SQL Serevr 7.0 (Cluster)..I already have an intsllation of 7.0(On a Cluster),so this means that 6.5 and sql 7 are on seperate cluster's ,if i try to upgrade from 6.5 Cluster to 7.0 Cluster is asks me to uncluster 6.5 and 7.0 is this correct ,assume i cannot break the cluster then what???.. what is the best way i can achieve this functinality.....
I have MS SQL 2000 and 2005 Express install on my computer. I would like to know where I can get some good beginner's training and I also need to know how to run sql scripts and import database to both.
I have a SQL server that my web host has provided but I don't know who to set it up! I'm currently have an MS Access database on my web site and I want to change it to MSSQL using the Access upsizing wizards, can anyone talk me through it?
hi there. this is my first post on this forum. im new to SQLServer so please go easy on me. :)
i am trying desperately to call a stored procedure from within another stored procedure. if i post my code below could somebody tell me where i am going wrong. the SP i have written is executing OK but the OUTPUT parameter Id_User is coming back as null, whereas it should be giving my a value there. i have tried changing the line 'EXEC sp_User_I' for 'INSERT INTO @User_Id EXEC sp_User_I' but this wont compile.
CREATE PROCEDURE sp_Account_I] @Username varchar(16), @Password varchar(88), @Surname varchar(32), @DateBirth datetime, @Email varchar(64), @Id_Account int OUTPUT, @Id_User int OUTPUT
I've been banging my head against this issue, and I haven't managed to find a solution. I was hoping that maybe somebody here has done something similar.
I am trying to get the latest available pricing from a Rate table, which is based on the customer ID and the provided date from another table (Table1).
This is what the code looks like, essentially:
select table1.* ,table2.* ,table3.Rate
from table1 left outer join table2 on table1.Id = table2.Id left outer join ( Select Top 1 Rate from RateTable Where RateTable.date < table1.date order by RateTable.date desc ) as table3 on table3.custId = table1.custId
I understood that table1.date can't be explicitly passed into the nested join within table3, but does anybody know a work around that can achieve the above example (the environment is SQL server 2000 and inside a view not on in a stored proc)?
Hi,I am completely new to the BCP utility and fairly new to SQL ServerI am learning from a book and I am trying the following example (the serverI'm learning on is called contractor and a password has not been give to thesa)bcp pubs..authors out authors.txt -C -r -t, -U sa -P -S contractorWhen I run this in Query Analyser i get the error message..Server: Msg 170, Level 15, State 1, Line 1Line 1: Incorrect syntax near '.'.I have tried puuting quotes around the database and the table name asfollows-bcp "pubs..authors" out authors.txt -C -r -t, -U sa -P -S contractorand get the errorServer: Msg 179, Level 15, State 1, Line 1Cannot use the OUTPUT option when passing a constant to a stored procedure.Please can anybody help me to get this first bit working?Thanks in anticipation.

I have a requirement to only rebuild the Clustered Indexes in the table ignoring the non clustered indexes as those are taken care of by the Clustered indexes.
In order to do that, I have taken the records based on the fragmentation %.
But unable to come up with a logic to only consider rebuilding the clustered indexes in the table.

My company needs a database. My first thought was to do it in Access, because it's available! But I wanted to check that that was smart, what its limitations are, when it's better to move to bigger / more expensive software, etc.
It's probably going to have several hundred thousand records in and will grow by more than a hundred thousand every year. Is there a size limit?
Not that many fields, though - it's not that complicated a database.
tables with words in Italian and English. Connect1(#id,id1,id2); connecting word form Eng with Ita translation. Connect2(#id,id1,id2); same for Italian.
Is this correct? 3. normalisation? Will this work?
if i am creating an SP then i only specify output parameters if the SP is to return a single set of values. is that correct? if my SP is returning multiple rows from a SELECT statement then i would not specify any parameters on the SP. can somebody clarify this for me. thanks!
I am new to database programming... i know the answer is somewhere in the past forums and i unfortunately i can't locate it... I have this problem i hope you can help me.
I am trying to insert values into table hosp_wareitem and one of it is the itemid where in i would like to get the item id of an existing medicine... (i hope you can understand me guys) here is my query.. right now im puzzled and i know the answer is already there.. i just cant see it...
set xact_abort on declare @id as integer begin transaction select @id (select medicines_id from hosp_medicines where medicines_id = medicines_id) insert into Hosp_WareItem (ItemID, Department_ID, SalesGL_Code, COSGL_Code, InventoryGL_Code, ExpenseGL_Code, ReadersFeeGL_Code, CreateBy, UpdateBy, DeleteBy, CreateDate, UpdateDate, DeleteDate) values (@ID, '1', 'AAA-111', 'AAA-000', 'AAA-112', '', '', '0', '', '', '1/1/1900 12:00:00 AM', '1/1/1900 12:00:00 AM', '') Update Hosp_Counter set Counter_ID = @ID where Table_Description = 'wareitem' commit transaction
it returns an error
(1 row(s) affected)
(24 row(s) affected)
Server: Msg 515, Level 16, State 2, Line 6 Cannot insert the value NULL into column 'ItemID', table 'Medix_Hospital.dbo.Hosp_wareitem'; column does not allow nulls. INSERT fails.
it tries to insert a null value in itemid because it cant get the value of the medicine_id.
