How to improve SQL table perfomance
Hi,
I have one table having 5lacks recording during the select operation the query is very slow. The table is in third normal form having primary key and index.Is there any other way to improve table performance....
Generally consider indexing ON clause and WHERE clause columns.
Also make sure the WHERE clause predicates are SARGable:

But make sure you understand the caveats you can run into!
It would be better to post the outcome of select * from v$version; first.
Also and execution plan would be nice to see.

How to integrate SQL table with the cahce
Hi,
In normal ASP.net application we use the
sqlCacheDependency to integrate the SQL server with the cache in ASP.NET, so that any change in the SQL table row will replace the cache with the latest data.
How to achieve the same in the Azure cache.
We need to integrate the SQL server with the Azure cache so that any change in the SQL table row should replace the cache with the latest data.Hi,
Cache in Azure is not different with ASP.NET, please see
http://msdn.microsoft.com/en-us/library/windowsazure/gg278356.aspx for more details, Azure provides for multiple types of persistent storage which can be leveraged for caching (Azure SQL Database, Azure Table Storage, Azure Blob Storage etc…). I would suggest
you read this article (http://www.dnnsoftware.com/blog/cid/425642/Understanding-Windows-Azure-Caching-for-building-high-performance-Websites
), because of we know where the cache data is, so we can sync up the data as expected.

How to access SQL tables from WebDynPro ABAP application ?
Hi,
I am trying a scenario, where I need to send an user ID to SQL server table (update/modify/delete) from webDynpro ABAP application.
Basically ,I am trying to know:---
a>How to write a SQL Connection from ABAP code within webdynpro ABAP application
b>What are the ways to do it.(by code or any other API/mechanism)
I appreciate if anybody knows this.
Thanks
PraveenHi,
The EXEC CONNECT ... is usually used in the procedural ABAP code. For this you can refer to the ABAPDOCU.
I dont have any sample code on the classes I listed try to check out them for the parameters and the methods they have.
In WD for Java, we have these connection classes to connect to any databsae server.
Or try to create an RFC with DESTINATION for this
Pls check out this link for this -

Hi ,
I have one table in sqlserver2008R2 that named "Customer" so that table hold the 1 Lac rows. Now I want send this table data to Excel/pdf with Columns using Storedprocedure.
I have tried this using xp_cmdshell so This is not working for me.
finally i want to get data in Excel and pdf also.
Please guide meYou can actually run an Excel Macro to grab the data from the SQL Server DB. Below are some samples.

Hi, I have to search record from one table that consists of more than 75 million row records. I've try to index in this table.
My problem is query result execute so slowly. How to increase the performance so i can get query result quickly ??
here is my explain plan :
PLAN_TABLE_OUTPUT
Plan hash value: 2042796762
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 12 | 45118 (10)| 00:09:02 |
|* 1 | TABLE ACCESS FULL| EID_DATA | 1 | 12 | 45118 (10)| 00:09:02 |
Predicate Information (identified by operation id):
1 - filter(RAWTOHEX("UID_DATA")='80297CFA353B0488')
13 rows selected
Thank you..Hi,
if you have an index on UID_DATA, the query cannot benefit from it because the column is wrapped in RAWTOHEX function. Creating a function-based index on RAWTOHEX(UID_DATA) should help. If this function call wasn't added to the query explicitly, then you should work on why it showed up there and how to get rid of it.
Next time you post a similar problem, please don't forget to include the query's text.
Best regards,

How to improve sql server query response time
I have a table that contains 60 million records with the following structure
1. SEQ_ID (Bigint),
2. SRM_CLIENT_ENTITIES_SEQ_ID (Bigint),
3. CUS_ENTITY_DATA_SEQ_ID (Bigint),
4. SRM_CLIENT_ENTITY_ATTRIBUTES_SEQ_ID (Bigint),
5. ATTRIBUTE_DATETIME (DateTime),
6. ATTRIBUTE_DECIMAL (Decimal(18,2)),
7. ATTRIBUTE_STRING (nvarchar(255)),
8. ATTRIBUTE_BOOLEAN (Char(1)),
9. SRM_CLIENTS_SEQ_ID (Bigint)
Clustered index with key SEQ_ID
Non unique non clustered index : I've following four composite indexes
a. SRM_CLIENTS_SEQ_ID, SRM_CLIENT_ENTITIES_SEQ_ID, SRM_CLIENT_ENTITY_ATTRIBTUES_SEQ_ID, ATTRIBUTE_DATETIME
b. SRM_CLIENTS_SEQ_ID, SRM_CLIENT_ENTITIES_SEQ_ID, SRM_CLIENT_ENTITY_ATTRIBTUES_SEQ_ID, ATTRIBUTE_DECIMAL
c. SRM_CLIENTS_SEQ_ID, SRM_CLIENT_ENTITIES_SEQ_ID, SRM_CLIENT_ENTITY_ATTRIBTUES_SEQ_ID, ATTRIBUTE_STRING
d. SRM_CLIENTS_SEQ_ID, SRM_CLIENT_ENTITIES_SEQ_ID, SRM_CLIENT_ENTITY_ATTRIBTUES_SEQ_ID, ATTRIBUTE_BOOLEAN
The problem is that when i execute a simple query over this table it does not return the results in an acceptable time.
Query:
SELECT CUS_ENTITY_DATA_SEQ_ID FROM dbo.CUS_PIVOT_NON_UNIQUE_INDEXES WHERE SRM_CLIENT_ENTITY_ATTRIBUTES_SEQ_ID = 51986 AND ATTRIBUTE_DECIMAL = 4150196
Execution Time : 2 seconds
ThanksDid you look at the execution plan.
The query may not use none of the indexes. The Clustered index is on SEQ_ID and the non clustered index doesn't start with SRM_CLIENT_ENTITY_ATTRIBUTES_SEQ_ID
OR ATTRIBUTE_DECIMAL.
The order of the columns in an index matters. Just for testing ( if it is not prod. environment) Create an NCI with SRM_CLIENT_ENTITY_ATTRIBUTES_SEQ_ID
and ATTRIBUTE_DECIMAL and check.

How to improve Query performance on large table in MS SQL Server 2008 R2
I have a table with 20 million records. What is the best option to improve query performance on this table. Is partitioning the table into filegroups is a best option or splitting the table into multiple smaller tables?
Hi bala197164,
First, I want to inform that both to partition the table into filegroups and split the table into multiple smaller tables can improve the table query performance, and they are fit for different situation. For example, our table have one hundred columns and
some columns are not related to this table object directly (for example, there is a table named userinfo to store user information, it has columns address_street, address_zip,address_ province columns, at this time, we can create a new table named as Address,
and add a foreign key in userinfo table references Address table), under this situation, by splitting a large table into smaller, individual tables, queries that access only a fraction of the data can run faster because there is less data to scan. Another
situation is our table records can be grouped easily, for example, there is a column named year to store information about product release date, at this time, we can partition the table into filegroups to improve the query performance. Usually, we perform
both of methods together. Additionally, we can add index to table to improve the query performance. For more detail information, please refer to the following document:

Hi all,
can you guys suggest me how can I use pl/sql tables for the below query to incresing the performance.
DECLARE
TYPE cur_typ IS REF CURSOR;
c cur_typ;
total_val varchar2(1000);
sql_stmt varchar2(1000);
freeform_name NUMBER;
freeform_id NUMBER;
imgname_rec EMC_FTW_PREVA.EMC_Image_C_Mungo%rowtype;
imgval_rec EMC_FTW_PREVA.EMC_Content_C_Mungo%rowtype;
CURSOR imgname_cur IS
select * from EMC_FTW_PREVA.EMC_Image_C_Mungo
where cs_ownerid in (
select id from EMC_FTW_PREVA.EMC_Image_C
where updateddate > '01-JUN-13'
and path is not null
and createddate != updateddate)
and cs_attrid = (select id from EMC_FTW_PREVA.EMC_ATTRIBUTE where name = 'Image_Upload');
BEGIN
OPEN imgname_cur;
LOOP
FETCH imgname_cur INTO imgname_rec;
EXIT WHEN imgname_cur%NOTFOUND;
total_val := 'EMC_Image_C_' || imgname_rec.cs_ownerid;
sql_stmt := 'SELECT instr(textvalue,''' || total_val || '''), cs_ownerid FROM EMC_FTW_PREVA.EMC_Content_C_Mungo a Where cs_attrid = (select id from EMC_FTW_PREVA.EMC_ATTRIBUTE where name = ' || '''' || 'Body_freeform' || '''' || ')';
OPEN c FOR sql_stmt;
LOOP
FETCH c INTO freeform_id,freeform_name;
EXIT WHEN c%NOTFOUND;
IF freeform_id > 0 THEN
dbms_output.put_line (imgname_rec.cs_ownerid || ',' || total_val || ',' || freeform_id || ',' || freeform_name);
END IF;
END LOOP;
CLOSE c;
END LOOP;
CLOSE imgname_cur;
END;
Thanks in Advance.can you guys suggest me how can I use pl/sql tables for the below query to incresing the performance.
There would be absolutely no point at all in improving the performance of code that has NO benefit.
The only result of executing that code is to possibly produce some lines of output AFTER the entire procedure if finished:
dbms_output.put_line (imgname_rec.cs_ownerid || ',' || total_val || ',' || freeform_id || ',' || freeform_name);
So first you need to explain:
1. what PROBLEM you are trying to solve?
2. why you are trying to use PL/SQL code to solve it.
3. why are you using 'slow by slow' (row by row) processing and then, for each row, opening a new cursor to query more data?
You should be using a single query rather than two nested cursors. But that begs the question of what the code is even supposed to be doing since the only output is going to a memory buffer. -
How to improve speed of queries that use ORM one table per concrete class
Hi,
Many tools that make ORM (Object Relational Mapping) like Castor, Hibernate, Toplink, JPOX, etc.., have the one table per concrete class feature that maps objects to follow structure:
CREATE TABLE ABSTRACTPRODUCT (
ID VARCHAR(8) NOT NULL,
DESCRIPTION VARCHAR(60) NOT NULL,
PRIMARY KEY(ID)
CREATE TABLE PRODUCT (
ID VARCHAR(8) NOT NULL REFERENCES ABSTRACTPRODUCT(ID),
CODE VARCHAR(10) NOT NULL,
PRICE DECIMAL(12,2),
PRIMARY KEY(ID)
CREATE UNIQUE INDEX iProduct ON Product(code)
CREATE TABLE BOOK (
ID VARCHAR(8) NOT NULL REFERENCES PRODUCT(ID),
AUTHOR VARCHAR(60) NOT NULL,
PRIMARY KEY (ID)
CREATE TABLE COMPACTDISK (
ID VARCHAR(8) NOT NULL REFERENCES PRODUCT(ID),
ARTIST VARCHAR(60) NOT NULL,
PRIMARY KEY(ID)
there is a way to improve queries like
SELECT
pd.code CODE,
abpd.description DESCRIPTION,
DECODE(bk.id,NULL,cd.artist,bk.author) PERSON
FROM
ABSTRACTPRODUCT abpd,
PRODUCT pd,
BOOK bk,
COMPACTDISK cd
WHERE
pd.id = abpd.id AND
bk.id(+) = abpd.id AND
cd.id(+) = abpd.id AND
pd.code like '101%'
or like this:
SELECT
pd.code CODE,
abpd.description DESCRIPTION,
DECODE(bk.id,NULL,cd.artist,bk.author) PERSON
FROM
ABSTRACTPRODUCT abpd,
PRODUCT pd,
BOOK bk,
COMPACTDISK cd
WHERE
pd.id = abpd.id AND
bk.id(+) = abpd.id AND
cd.id(+) = abpd.id AND
abpd.description like '%STARS%' AND
pd.price BETWEEN 1 AND 10
think in a table with many rows, then exists something inside MaxDB to improve this type of queries? like some anotations on SQL? or declare tables that extends another by PK? on other databases i managed this using Materialized Views, but i think that this can be faster just using PK, i'm wrong? the better is to consolidate all tables in one table? what is the impact on database size with this consolidation?
note: with consolidation i will miss NOT NULL constraint at database side.
thanks for any insight.
ClóvisHi Lars,
i dont understand because the optimizer get that Index for TM at execution plan, and because dont use the join via KEY column, note the WHERE clause is "TM.OID = MF.MY_TIPO_MOVIMENTO" by the key column, and the optimizer uses an INDEX that the indexed column is ID_SYS, that isnt and cant be a primary key, because its not UNIQUE, follow the index columns:
indexes of TipoMovimento
INDEXNAME COLUMNNAME SORT COLUMNNO DATATYPE LEN INDEX_USED FILESTATE DISABLED
ITIPOMOVIMENTO TIPO ASC 1 VARCHAR 2 220546 OK NO
ITIPOMOVIMENTO ID_SYS ASC 2 CHAR 6 220546 OK NO
ITIPOMOVIMENTO MY_CONTA_DEBITO ASC 3 CHAR 8 220546 OK NO
ITIPOMOVIMENTO MY_CONTA_CREDITO ASC 4 CHAR 8 220546 OK NO
ITIPOMOVIMENTO1 ID_SYS ASC 1 CHAR 6 567358 OK NO
ITIPOMOVIMENTO2 DESCRICAO ASC 1 VARCHAR 60 94692 OK NO
after i create the index iTituloCobrancaX7 on TituloCobranca(OID,DATA_VENCIMENTO) in a backup instance and get surprised with the follow explain:
OWNER TABLENAME COLUMN_OR_INDEX STRATEGY PAGECOUNT
TC ITITULOCOBRANCA1 RANGE CONDITION FOR INDEX 5368
DATA_VENCIMENTO (USED INDEX COLUMN)
MF OID JOIN VIA KEY COLUMN 9427
TM OID JOIN VIA KEY COLUMN 22
TABLE HASHED
PS OID JOIN VIA KEY COLUMN 1350
BOL OID JOIN VIA KEY COLUMN 497
NO TEMPORARY RESULTS CREATED
JDBC_CURSOR_19 RESULT IS COPIED , COSTVALUE IS 988
note that now the optimizer gets the index ITITULOCOBRANCA1 as i expected, if i drop the new index iTituloCobrancaX7 the optimizer still getting this execution plan, with this the query executes at 110 ms, with that great news i do same thing in the production system, but the execution plan dont changes, and i still getting a long execution time this time at 413516 ms. maybe the problem is how optimizer measure my tables.
i checked in DBAnalyser that the problem is catalog cache hit rate (we discussed this at [catalog cache hit rate, how to increase?|;
) and the low selectivity of this SQL command, then its because of this that to achieve a better selectivity i must have an index with, MF.MY_SACADO, MF.TIPO and TC.DATA_VENCIMENTO, as explained in previous posts, since this type of index inside MaxDB isnt possible, i have no choice to speed this type of query without changing tables structure.
MaxDB developers can develop this type of index? or a feature like this dont have any plans to be made?
if no, i must create another schema, to consolidate tables to speed queries on my system, but with this consolidation i will get more overhead, i must solve the less selectivity because i think if the data on tables increase, the query becomes impossible, i see that CREATE INDEX supports FUNCTION, maybe a FUNCTION that join data of two tables can solve this?

How to delete the Table Contents before inserting records into SQL table ?
Hello Experts,
I have a scenario where in I have to Pick up some records from SAP RFC & insert into SQL table.
i know how to do this scenario but the proble with this is before inserting we first have to ZAP the SQL table & insert a new records. One more twist is The Triggering is happening from SAP side with Sender RFC. If this would have been from SQL Side i could have written a Stored Procedure/ Trigger & could have called this before the SENDER JDBC communciation channel picks up the Triggering event from SQL side.
So how to do this scenarioin XI, First deleting all the Records of SQL table & then inserting the new reocrds. without using the BPM.
Regards,
Umeshhi umesh,
you can achieve this by writing SQL query in message mapping level..
refer this link:

How can I read a file with ASCII Special Character into a SQL table using SSIS 2008?
I've tried everything to read this file and am getting no where. Help how can I read this file and load a SQL table?
RS - AscII - 30 (Record Separator)
GS - AscII - 29 (Group Separator)
Thank you for your assistance - Covi
Mark CovianWe can use script component as source/transformation to read the text file and assign the contains to a string. Split the string by chr(30) i.e RS and finally stored into an array or write to the output buffer of the script component.
For example on how to use script component refer this link

How to use Temporary Table in PL-SQL
In MySQL there is no Temporary table concept.
So for intermediate calculation I have created a table as below
create table SequenceTempTable
SessionId VARCHAR(50),
Sequence VARCHAR(500),
CreatedDate DATE
) ENGINE=MEMORY;
Whenever I invoke a SP, I load the data into SequenceTempTable using Session Id as below
CREATE PROCEDURE `GetSequence`(
IN Start_Date VARCHAR(25),
IN End_Date VARCHAR(25)
BEGIN
SELECT UUID() INTO v_SessionId;
INSERT INTO SequenceTempTable values (v_SessionId,'1,2,5,3',now());
required code
DELETE FROM SequenceTempTable WHERE SessionId = v_SessionId;
COMMIT;
END;
i.e. I have created a table as temporary table (created once),
and load the data using Session Id and once session specific intermediate computation done,
I deleted the session specific data.
Could you give me examples of How to use Temporary table in PL-SQL code with respect to my above example.
Because I have gone through creating Temporary table but I stuck with use in PL-SQL. I mean to say Is there any need of creating table in advance before invoking SP.
And one more thing as in MySQL temp table I created which is using MEMORY engine i.e. this table will always be in MEMORY so there is no need of writing data on disk.
Regards
SanjeevHi Sanjeev
Read about GTT here
http://www.oracle-base.com/articles/8i/TemporaryTables.php
GTT always contains just session specific data. \
In case you want to use the GTT in the same session again you can use option
ON COMMIT PRESERVE ROWS;
Or if it is used just once in the session use can use
ON COMMIT DELETE ROWS;
Do remember that for GTT the data of one session can not be accessed in other session.
Also you can go away with Delete from GTT if not used again in same session.
