Why the Indexes on table slow down the DML operation on table, what is the exact reason?

I have a table that is riddled with weird characters. So far I have found an escape character for PDF files and a trademark sign. These characters are crashing my SSIS packages. I am able to remove these characters with an update script...
Update TABLE
set LEAD_NOTES__C = Replace(LEAD_NOTES__C, nchar(65533) COLLATE Latin1_General_BIN2, '!');
Update TABLE
set LEAD_NOTES__C = Replace(LEAD_NOTES__C, nchar(1671) COLLATE Latin1_General_BIN2, '!');
This works fine, but my question is...
I would like to write a script that removes all foreign characters with the exception of the normal characters like (@,#,$,%,etc). I need a dynamic process that handles this so I am not losing time sifting through over 20,000 rows of data and changing my update script to remove a specific column. Although this method works, I would prefer a dynamic query. I intend to wrap this in a stored procedure that loops through all columns in a table (as parameter).
Is there a performance limit on the number of indexes per table / database ? With Filtered indexes there appear to be many more opportunities for more finely defined, and therefore smaller indexes resulting in many more indexes on a single table.

I have resulting rows from a query similar to the following:
The data is coming from a single table that contains only one coverage code column and one coverage code date, but the end user wants the two coverage code types and dates combined into a single row. So the SELECT looks something like this:
SELECT
[Employee ID] = emp.employee_id,
[Coverage Code 1] = enr.coverage_code,
[Coverage Date 1] = enr.coverage_date,
[Coverage Code 2] = case when enr.product_type = 'Accident.Accident'
then enr.coverage_code else NULL end,
[Code] ....
I basically want to merge the like Employee ID's together into a single row like the following:
I know I have done this before and it is probably pretty simple.
I am looking a script which allow me add single coilumn to multiple table of my database.
For Example :-
I am having 4 table
1-Emp , 2-Dept , 3-Location , 4-Salary like this I have around 100 of table
Now I want to run below command to add column Rowchecksum in all table where table name start with Archivebbx keywords.
Alter table EMP
Add Rowchecksum varbinary(8000)
I am trying to create a check command that ensures only A'B','c','D','E','F','G and s1, s2 can be inserted in the table, is this even applicable? Heres my code:
Create Table GRADE (

CONSTRAINT check_grade
CHECK (substr(Grade = 'A','B','c','D','E','F','G')),
Salary_Scale VARCHAR2(2) CONSTRAINT check_SScale

I am trying to insert values in a single table with four columns from 4 different sources. is it possible to run these 4 insertions in parallel. all these insertion are independent of each other
View 3 Replies View RelatedI have created a trigger that is set off every time a new item has been added to TableA.The trigger then inserts 4 rows into TableB that contains two columns (item, task type).
Each row will have the same item, but with a different task type.ie.
TableA.item, 'Planning'
TableA.item, 'Design'
TableA.item, 'Program'
TableA.item, 'Production'
How can I do this with tSQL using a single select statement?
where including/excluding a single column in an empty staging table would influence a resultset returning from distributed query? Both servers are SQL Server 2012. Nothing special about the staging table. It contains 12 columns with a mixture of INT and NVARCHAR(256) columns. In one case I exclude the column and the query returns in 17 seconds. When I include it the query does not return. Excluding the INSERT INTO the staging table and query returns in 17 secs with and without the column.

I have a script to rebuild and reorganize indexes for sybase i.e reorg rebuild index... like command i have. Now i want similar command for MSSQLSqlserver.plz help me.
I am new to SQL and I haven't written any scripts in the past. I thought I would give it a go. Basically, I am trying to write a script that will check if a database has more than one log files, free the VLFs that belong to the secondary log files and then remove them. I created a database named rDb as this link suggests and followed the steps.
[URL] ....
It works. However, I want to have to run just 1 script that will do the entire job. This is what I have gotten so far and it doesn't work:
create table #tempsysdatabase(
File_id int,
file_guid varchar(50),
type_desc varchar (20),
data_space_id int,
name nvarchar (50),
state int,
[Code] ....
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???

I'm evaluating SQL 2005 Everywhere Edition for use by our desktop application. I'm a traditional SQL Server developer and I rely heavily on stored-procedures to encapsulate basic data manipulations across multiple tables and inside multi-statement transactions.
I was excited to see an in-process version of SQL released and my thought was "this is great... now I can ditch the tediousness of individual OLEDB/.NET commands, and write batches of T-SQL and just focus on the data manipulations". But, alas, it seems I cannot. Why is SQL Everywhere Edition limited to executing a single SQL statement at a time?
For example, my application would like to update mutlipe rows in one table, delete multiple rows from another, and insert multiple rows into a third. I can do that with 3 T-SQL statements in a single small batch in a very readable way with full blown SQL Server. (and I can put that batch in a stored procedure and re-use it efficiently later.) If I contemplate how to do that with OLEDB and the single statement limitation of SQL Everywhere, it's a lot more code and a lot less appealing/maintainable. I want as much of my app to be using declarative code and as little as possible tied up in tedious OLEDB calls. Is this not possible with SQL Everywhere Edition?
Hi guys.
acutally my network dept. has change the backup file server IP address.. i m now hving problem for taking backup.

is there any simple script that just update the device path folder..
Thanks and looking foward.

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.
Any disadvantage of having too many indexes?

I created a mirrored DB, added a new datafile to the principal using a path the mirror can't access. As a result the mirroring session was suspended because the mirror stated: "CREATE FILE encountered operating system error 3(The system cannot find the path specified.) while attempting to open or create the physical file".
Fine, so I disabled mirroring on the principal (SET PARTNER OFF) which worked just fine, but the mirror stayed in a mirrored state, Object Explorer saying:"(Mirror, Disconnected / In Recovery). Sooo, I tried to disable db mirroring on the mirror using ALTER DATABASE db SET PARTNER OFF;, which completed successfully, but the DB STILL remained in a mirrored-configuration.
I tried ALTER DATABASE db SET PARTNER FORCE_SERVICE_ALLOW_DATA_LOSS which resulted in
"Msg 1404, Level 16, State 4, Line 1
The command failed because the database mirror is busy. Reissue the command later."
I tried taking the DB offline or restoring it from a backup, but all these operations resulted in "The operation cannot be performed on database "db" because it is involved in a database mirroring session or an availability group."
The only solution I can think of at the moment is shutting down the instance and deleting the data and log-files of the mirrored db, which would be just fine because this is just a test installation, but it would be not quite as easy in a productive environment.
Is there any other way to remove the mirrored state from a disconnected mirror or to simply get rid of the db entirely to perform a recovery?
As part of patching i need to remove the database from availability group and add the database after patching is done , how can i achieve this ?
View 2 Replies View RelatedWhat are driving criteria for creating filtered indexes on SQL server. I am trying to analyze the index stats through DMV,histogram and have to analyze if the filtered indexes should be created on tables. This exercise has to be done for all the transaction tables on the database. What are the approaches I should be looking on?
There was a deadlock on the DB because of huge writes on one of the big tables. Having filtered index on this table for the effected column would reduce the time taken for write operations. Hence we are looking for creating filtered indexes appropriately
How Indexes are allocates on pages? And If a CREATE INDEX Statement Executed on a query Window, Query processor meets and executes these query. However it was meet, who decides to separate indexes onto pages? Storage Engine or Query Processor(Query Optimizer)? Does it work like UPDATE-Statements in Query Optimizer?
