Difference between is_published and is_replicated columns of sys.tables

Hello,
Can someone please tell me the exact difference between is_published and is_replicated columns of sys.tables? I know is_published is inherited from sys.objects table , but purpose of both the columns are same. However sometimes for some replicated tables
i have seen is_published = 1 and is_replicated = 0 and for another published database tables value of both columns are 1.
It is bit confusing. Can you please explain?
Thanks in Advance.
-Malkesh

Is published has a value of 1 for snapshot and transactional replication, and peer to peer.
Is_replicated has a value of 1 for transactional, p2p, and cdc.
The values will be 1 for both the pub and the subscriber in p2p, but are 0 for both for all other subscription types.
The values are always 0 for merge.

  • Difference between systimestamp and a column of timestamp

    Hi ,
    I want to get the minutes difference between systimestamp and a column which has value of certain timestamp
    Table1
    InsertTmstmp --> 03-FEB-10 01.43.07.865272000 AM
    now how can I get the difference in minutes between systimestamp - InsertTmstmp ?
    I tried the following
    select EXTRACT(minute FROM systimestamp - InsertTmstmp ) from table1 where seq_id = '9';
    but this was not giving proper results .
    For example if InsertTmstmp --> 03-FEB-10 01.43.07.865272000 AM
    and systimestamp is 03-FEB-10 02.03.15.678084000 AM GMT-07:00. then the select query is returning 50.
    and when I query
    select systimestamp - InsertTmstmp from table1 ,, this is not returning any value . ( i saw in some sites this query returning values ).
    Thanks in advance

    May be like this?
    with t
    as
    select systimestamp - (systimestamp-1) dt from dual
    select dt,
           extract(day from dt)*24*60+extract(hour from dt)*60+extract(minute from dt)+extract(second from dt)/60 interval_in_min
      from t

  • Difference between JCDS and CDHDR

    Hi;
    what is exactly the difference between JCDS and CDHDR ?
    Thanks.

    JCDS-table of Change documents for System/User statuses
    if we create a role and after that what ever changes made to that role, all the changes are recorded in the database. The changes recorded in the database is called change documents in terms of client copy.

    CDHDR- table of Change document header
    Change pointers SAP R/3 objects that mark changes in SAP data. Change pointers are managed by sharing mechanisms in a Master Data and changes are based on documents (CD) objects. CD objects record the changes to master data at a field level. These changes are recorded in Tables CDHDR (header table)

  • What is the difference between tkprof and explainplan

    Hi,
    what is the difference between tkprof and explainplan.

    Execution Plans and the EXPLAIN PLAN Statement
    Before the database server can execute a SQL statement, Oracle must first parse the statement and develop an execution plan. The execution plan is a task list of sorts that decomposes a potentially complex SQL operation into a series of basic data access operations. For example, a query against the dept table might have an execution plan that consists of an index lookup on the deptno index, followed by a table access by ROWID.
    The EXPLAIN PLAN statement allows you to submit a SQL statement to Oracle and have the database prepare the execution plan for the statement without actually executing it. The execution plan is made available to you in the form of rows inserted into a special table called a plan table. You may query the rows in the plan table using ordinary SELECT statements in order to see the steps of the execution plan for the statement you explained. You may keep multiple execution plans in the plan table by assigning each a unique statement_id. Or you may choose to delete the rows from the plan table after you are finished looking at the execution plan. You can also roll back an EXPLAIN PLAN statement in order to remove the execution plan from the plan table.
    The EXPLAIN PLAN statement runs very quickly, even if the statement being explained is a query that might run for hours. This is because the statement is simply parsed and its execution plan saved into the plan table. The actual statement is never executed by EXPLAIN PLAN. Along these same lines, if the statement being explained includes bind variables, the variables never need to actually be bound. The values that would be bound are not relevant since the statement is not actually executed.
    You don’t need any special system privileges in order to use the EXPLAIN PLAN statement. However, you do need to have INSERT privileges on the plan table, and you must have sufficient privileges to execute the statement you are trying to explain. The one difference is that in order to explain a statement that involves views, you must have privileges on all of the tables that make up the view. If you don’t, you’ll get an “ORA-01039: insufficient privileges on underlying objects of the view” error.
    The columns that make up the plan table are as follows:
    Name Null? Type
    STATEMENT_ID VARCHAR2(30)
    TIMESTAMP DATE
    REMARKS VARCHAR2(80)
    OPERATION VARCHAR2(30)
    OPTIONS VARCHAR2(30)
    OBJECT_NODE VARCHAR2(128)
    OBJECT_OWNER VARCHAR2(30)
    OBJECT_NAME VARCHAR2(30)
    OBJECT_INSTANCE NUMBER(38)
    OBJECT_TYPE VARCHAR2(30)
    OPTIMIZER VARCHAR2(255)
    SEARCH_COLUMNS NUMBER
    ID NUMBER(38)
    PARENT_ID NUMBER(38)
    POSITION NUMBER(38)
    COST NUMBER(38)
    CARDINALITY NUMBER(38)
    BYTES NUMBER(38)
    OTHER_TAG VARCHAR2(255)
    PARTITION_START VARCHAR2(255)
    PARTITION_STOP VARCHAR2(255)
    PARTITION_ID NUMBER(38)
    OTHER LONG
    DISTRIBUTION VARCHAR2(30)
    There are other ways to view execution plans besides issuing the EXPLAIN PLAN statement and querying the plan table. SQL*Plus can automatically display an execution plan after each statement is executed. Also, there are many GUI tools available that allow you to click on a SQL statement in the shared pool and view its execution plan. In addition, TKPROF can optionally include execution plans in its reports as well.
    Trace Files and the TKPROF Utility
    TKPROF is a utility that you invoke at the operating system level in order to analyze SQL trace files and generate reports that present the trace information in a readable form. Although the details of how you invoke TKPROF vary from one platform to the next, Oracle Corporation provides TKPROF with all releases of the database and the basic functionality is the same on all platforms.
    The term trace file may be a bit confusing. More recent releases of the database offer a product called Oracle Trace Collection Services. Also, Net8 is capable of generating trace files. SQL trace files are entirely different. SQL trace is a facility that you enable or disable for individual database sessions or for the entire instance as a whole. When SQL trace is enabled for a database session, the Oracle server process handling that session writes detailed information about all database calls and operations to a trace file. Special database events may be set in order to cause Oracle to write even more specific information—such as the values of bind variables—into the trace file.
    SQL trace files are text files that, strictly speaking, are human readable. However, they are extremely verbose, repetitive, and cryptic. For example, if an application opens a cursor and fetches 1000 rows from the cursor one row at a time, there will be over 1000 separate entries in the trace file.
    TKPROF is a program that you invoke at the operating system command prompt in order to reformat the trace file into a format that is much easier to comprehend. Each SQL statement is displayed in the report, along with counts of how many times it was parsed, executed, and fetched. CPU time, elapsed time, logical reads, physical reads, and rows processed are also reported, along with information about recursion level and misses in the library cache. TKPROF can also optionally include the execution plan for each SQL statement in the report, along with counts of how many rows were processed at each step of the execution plan.
    The SQL statements can be listed in a TKPROF report in the order of how much resource they used, if desired. Also, recursive SQL statements issued by the SYS user to manage the data dictionary can be included or excluded, and TKPROF can write SQL statements from the traced session into a spool file.
    How EXPLAIN PLAN and TKPROF Aid in the Application Tuning Process
    EXPLAIN PLAN and TKPROF are valuable tools in the tuning process. Tuning at the application level typically yields the most dramatic results, and these two tools can help with the tuning in many different ways.
    EXPLAIN PLAN and TKPROF allow you to proactively tune an application while it is in development. It is relatively easy to enable SQL trace, run an application in a test environment, run TKPROF on the trace file, and review the output to determine if application or schema changes are called for. EXPLAIN PLAN is handy for evaluating individual SQL statements.
    By reviewing execution plans, you can also validate the scalability of an application. If the database operations are dependent upon full table scans of tables that could grow quite large, then there may be scalability problems ahead. On the other hand, if large tables are accessed via selective indexes, then scalability may not be a problem.
    EXPLAIN PLAN and TKPROF may also be used in an existing production environment in order to zero in on resource intensive operations and get insights into how the code may be optimized. TKPROF can further be used to quantify the resources required by specific database operations or application functions.
    EXPLAIN PLAN is also handy for estimating resource requirements in advance. Suppose you have an ad hoc reporting request against a very large database. Running queries through EXPLAIN PLAN will let you determine in advance if the queries are feasible or if they will be resource intensive and will take unacceptably long to run.

  • Difference between char and varchar, also the difference between varchar2

    Hi,
    Can anyone explain me the difference between char and varchar, and also the difference between varchar and varchar2...

    Varchar2 is variable width character data type, so if you define column with width 20 and insert only one character to tis column only, one character will be stored in database. Char is not variable width so when you define column with width 20 and insert one character to this column it will be right padded with 19 spaces to desired length, so you will store 20 characters in the dattabase (follow the example 1). Varchar data type from Oracle 9i is automaticlly promoted to varchar2 (follow example 2)
    Example 1:
    SQL> create table tchar(text1 char(10), text2 varchar2(10))
    2 /
    Table created.
    SQL> insert into tchar values('krystian','krystian')
    2 /
    1 row created.
    SQL> select text1, length(text1), text2, length(text2)
    2 from tchar
    3 /
    TEXT1 LENGTH(TEXT1) TEXT2 LENGTH(TEXT2)
    krystian 10 krystian 8
    Example 2:
    create table tvarchar(text varchar(10))
    SQL> select table_name,column_name,data_type
    2 from user_tab_columns
    3 where table_name = 'TVARCHAR'
    4 /
    TABLE_NAME COLUMN_NAME DATA_TYPE
    TVARCHAR TEXT VARCHAR2

  • What is the difference between exists and in

    hi all
    if i have these queries
    1- select ename from emp where ename in ( select ename from emp where empno=10)
    and
    2- select ename from emp where exists ( select ename from emp where empno=10)
    what is the difference between exists and in is that only when i use in i have to bring the field name or what.... i mean in a complex SQL queries is it will give the same answer
    Thanks

    You get two entirely different result sets that may be the same. Haah! What do I mean by that.
    SQL> select table_name from user_tables;
    TABLE_NAME
    BAR
    FOO
    2 rows selected.
    SQL> select table_name from user_tables where table_name in (select table_name from user_tables where table_name = 'FOO');
    TABLE_NAME
    FOO
    1 row selected.
    SQL> select table_name from user_tables where exists(select table_name from user_tables where table_name = 'FOO');
    TABLE_NAME
    BAR
    FOO
    2 rows selected.So, why is this? the WHERE EXISTS means 'if the next is true', much like where 1=1 being always true and 1=2 being always false. In this case, where exists could be TRUE or FALSE, depending on the subquery.
    WHERE EXISTS can be useful for something like testing if we have data, without actually having to return columns.
    So, if you want to see if an employee exists you might say
    SELECT 1 FROM DUAL WHERE EXISTS( select * from emp where empid = 10);
    If there is a row in emp for empid=10, then you get back 1 from dual;
    This is what I call an 'optimistic' lookup because the WHERE EXISTS ends as soon as there is a hit. It does not care how many - only that at least one exists. It is optimistic because it will continue processing the table lookup until either it hits or reaches the end of the table - for a non-indexed query.

  • Difference between CHAR and VARCHAR2 datatype

    Difference between CHAR and VARCHAR2 datatype
    CHAR datatype
    If you have an employee name column with size 10; ename CHAR(10) and If a column value 'JOHN' is inserted, 6 empty spaces will be inserted to the right of the value. If this was a VARCHAR column; ename VARCHAR2(10). How would it handle the column value 'JOHN' ?

    The CHAR datatype stores fixed-length character strings, and Oracle compares CHAR values using blank-padded comparison semantics.
    Where as the VARCHAR2 datatype stores variable-length character strings, and Oracle compares VARCHAR2 values using nonpadded comparison semantics.
    This is important when comparing or joining on the columns having these datatypes;

  • What's the Difference Between OLAP and OLTP?

    HI,
    What's the difference between OLAP and OLTP ? and which one is Best?
    -Arun.M.D

    Hi,
       The big difference when designing for OLAP versus OLTP is rooted in the basics of how the tables are going to be used. I'll discuss OLTP versus OLAP in context to the design of dimensional data warehouses. However, keep in mind there are more architectural components that make up a mature, best practices data warehouse than just the dimensional data warehouse.
    Corporate Information Factory, 2nd Edition by W. H. Inmon, Claudia Imhoff, Ryan Sousa
    Building the Data Warehouse, 2nd Edition by W. H. Inmon
    With OLTP, the tables are designed to facilitate fast inserting, updating and deleting rows of information with each logical unit of work. The database design is highly normalized. Usually and at least to 3NF. Each logical unit of work in an online application will have a relatively small scope with regard to the number of tables that are referenced and/or updated. Also the online application itself handles the majority of the work for joining data to facilitate the screen functions. This means the user doesn't have to worry about traversing across large data relationship paths. A heavy dose of lookup/reference tables and much focus on referential integrity between foreign keys. The physical design of the database needs to take into considerations the need for inserting rows when deciding on physical space settings. A good book for getting a solid base understanding of modeling for OLTP is The Data Modeling Handbook: A Best-Practice Approach to Building Quality Data Models by Michael C. Reingruber, William W. Gregory.
    Example: Let's say we have a purchase oder management system. We need to be able to take orders for our customers, and we need to be able to sell many items on each order. We need to capture the store that sold the item, the customer that bought the item (and where we need to ship things and where to bill) and we need to make sure that we pull from the valid store_items to get the correct item number, description and price. Our OLTP data model will contain a CUSTOMER_MASTER, A CUSTOMER_ADDRESS_MASTER, A STORE_MASTER, AN ITEM_MASTER, AN ITEM_PRICE_MASTER, A PURCHASE_ORDER_MASTER AND A PURCHASE_ORDER_LINE_ITEM table. Then we might have a series of M:M relationships for example. An ITEM might have a different price for specific time periods for specific stores.
    With OLAP, the tables are designed to facilitate easy access to information. Today's OLAP tools make the job of developing a query very easy. However, you still want to minimize the extensiveness of the relational model in an OLAP application. Users don't have the wills and means to learn how to work through a complex maze of table relationships. So you'll design your tables with a high degree of denormalization. The most prevalent design scheme for OLAP is the Star-Schema, popularized by Ralph Kimball. The star schema has a FACT table that contains the elements of data that are used arithmatically (counting, summing, averaging, etc.) The FACT Table is surrounded by lookup tables called Dimensions. Each Dimension table provides a reference to those things that you want to analyze by. A good book to understand how to design OLAP solutions is The Data Warehouse Toolkit: Practical Techniques for Building Dimensional Data Warehouses by Ralph Kimball.
    Example: let's say we want to see some key measures about purchases. We want to know how many items and the sales amount that are purchased by what kind of customer across which stores. The FACT table will contain a column for Qty-purchased and Purchase Amount. The DIMENSION tables will include the ITEM_DESC (contains the item_id & Description), the CUSTOMER_TYPE, the STORE (Store_id & store name), and TIME (contains calendar information such as the date, the month_end_date, quarter_end_date, day_of_week, etc).

  • Difference between ALL_TAB_COLUMNS and USER_TAB_COLUMNS

    Hi,
    I want to know the difference between ALL_tab_columns and User_tab_columns.
    Kindly tell me solution

    ALL_TAB_COLUMNS describes the columns of the tables, views, and clusters accessible to the current user.
    USER_TAB_COLUMNS describes the columns of the tables, views, and clusters owned by the current user. Its columns (except for OWNER) are the same as those in "ALL_TAB_COLUMNS".

  • Difference between ALV and Table control

    Hi folks,
    i want to know the major differences between AlV and table controls.
    i know that table control is designed in screen painter, but i want to know the major diff between Table control and ALV.
    helpful answers will be rewarded.
    Regards,
    Naveen

    Hi Naveen,
    Basically ALV is a way to display the output and Table Control is designed in screen painter through which you can get entries in Table Control, can delete some records etc for further processing and  its not use only for Display.
    <b>ALV is Application List viewer:-</b>
    Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length. 
    In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output. 
    <b>TABLE CONTROL:-</b>
    ABAP offers two mechanisms for displaying and using table data in a screen. These mechanisms are table controls and step loops. Table controls and step loops are types of screen tables you can add to a screen in the Screen Painter.
    Rewards if useful.
    Regards,
    Shilpi

    See the forum FAQ
    SQL and PL/SQL FAQ
    "3. How to improve the performance of my query?"
    2)What approach you take to tune query? Do you use Hints?Hints can help.
    Even more helpful is writing the SQL efficiently (avoiding multiple scans of the same table, filtering early, using built-in rather than user-defined functions, ...), creating and using indexes, and, for large tables, partitioning.
    Table design can have a big impact on performace.
    Look for ways to do part of what you need before the query. This includes denormalizing (when appropriate), the kind of pre-digesting that often takes place in data warehouses, function-based indexes, and, starting in Oracle 11, virtual columns.
    3)Where did you tune the query and what are the issue with query?Either this question is a vague summary of the entire thread, or I don't understand it. Can you re-phrase this part?
    4)What is difference between RBO and CBO? where u use RBO and CBO.Basically, use RBO if you have Oracle 7 or earlier.

  • MAIN DIFFERENCES BETWEEN PARALLEL AND SEQUENTAIL PRCESSING???

    HI PALS,
    I WANT THE COMPLETE DIFFERENCES BETWEEN PARALLEL AND SEQUENTIAL PROCESSING!
    IN THE CONTEXT OF RFC.

    Hi
    Parallel Processing
    To achieve a balanced distribution of the system load, you can use destination additions to execute function modules in parallel tasks in any application server or in a predefined application server group of an SAP system.
    Parallel-processing is implemented with a special variant of asynchonous RFC. Itu2019s important that you use only the correct variant for your own parallel processing applications: the CALL FUNCTION STARTING NEW TASK DESTINATION IN GROUP keyword. Using other variants of asynchronous RFC circumvents the built-in safeguards in the correct keyword, and can bring your system to its knees
    Details are discussed in the following subsections:
    ·        Prerequisites for Parallel Processing
    ·        Function Modules and ABAP Keywords for Parallel Processing
    ·        Managing Resources in Parallel Processing
    Prerequisites for Parallel Processing
    Before you implement parallel processing, make sure that your application and your SAP system meet these requirements:
    ·        Logically-independent units of work:
    The data processing task that is to be carried out in parallel must be logically independent of other instances of the task. That is, the task can be carried out without reference to other records from the same data set that are also being processed in parallel, and the task is not dependent upon the results of others of the parallel operations. For example, parallel processing is not suitable for data that must be sequentially processed or in which the processing of one data item is dependent upon the processing of another item of the data.
    By definition, there is no guarantee that data will be processed in a particular order in parallel processing or that a particular result will be available at a given point in processing. 
    ·        ABAP requirements:
    ¡        The function module that you call must be marked as externally callable. This attribute is specified in the Remote function call supported field in the function module definition (transaction SE37).
    ¡        The called function module may not include a function call to the destination u201CBACK.u201D
    ¡        The calling program should not change to a new internal session after making an asynchronous RFC call. That is, you should not use SUBMIT or CALL TRANSACTION in such a report after using CALL FUNCTION STARTING NEW TASK.  
    ¡        You cannot use the CALL FUNCTION STARTING NEW TASK DESTINATION IN GROUP keyword to start external programs. 
    ·        System resources: 
    In order to process tasks from parallel jobs, a server in your SAP system must have at least 3 dialog work processes. It must also meet the workload criteria of the parallel processing system: Dispatcher queue less than 10% full, at least one dialog work process free for processing tasks from the parallel job.
    Function Modules and ABAP Keywords for Parallel Processing
    You can implement parallel processing in your applications by using the following function modules and ABAP keywords:
    ·        SPBT_INITIALIZE: Optional function module. 
    Use to determine the availability of resources for parallel processing. 
    You can do the following:
    ¡        check that the parallel processing group that you have specified is correct.
    ¡        find out how many work processes are available so that you can more efficiently size the packets of data that are to be processed in your data.
    ·        CALL FUNCTION Remotefunction STARTING NEW TASK Taskname DESTINATION IN GROUP:
    With this ABAP statement, you are telling the SAP system to process function module calls in parallel. Typically, youu2019ll place this keyword in a loop in which you divide up the data that is to be processed into work packets. You can pass the data that is to be processed in the form of an internal table (EXPORT, TABLE arguments). The keyword implements parallel processing by dispatching asynchronous RFC calls to the servers that are available in the RFC server group specified for the processing.
    Note that your RFC calls with CALL FUNCTION are processed in work processes of type DIALOG. The DIALOG limit on processing of one dialog step (by default 300 seconds, system profile parameter rdisp/max_wprun_time) applies to these RFC calls. Keep this limit in mind when you divide up data for parallel processing calls. 
    ·        SPBT_GET_PP_DESTINATION: Optional function module. 
    Call immediately after the CALL FUNCTION keyword to get the name of the server on which the parallel processing task will be run. 
    ·        SPBT_DO_NOT_USE_SERVER: Optional function module. 
    Excludes a particular server from further use for processing parallel processing tasks. Use in conjunction with SPBT_GET_PP_DESTINATION if you determine that a particular server is not available for parallel processing (for example, COMMUNICATION FAILURE exception if a server becomes unavailable).
    ·        WAIT: ABAP keyword
    WAIT UNTIL
    Required if you wish to wait for all of the asynchronous parallel tasks created with CALL FUNCTION to return. This is normally a requirement for orderly background processing. May be used only if the CALL FUNCTION includes the PERFORMING ON RETURN addition.
    ·        RECEIVE: ABAP keyword
    RECEIVE RESULTS FROM FUNCTION Remotefunction
    Required if you wish to receive the results of the processing of an asynchronous RFC. RECEIVE retrieves IMPORT and TABLE parameters as well as messages and return codes.
    Managing Resources in Parallel Processing
    You use the following destination additions to perform parallel execution of function modules (asynchronous calls) in the SAP system:
    In a predefined group of application servers:
    CALL FUNCTION Remotefunction STARTING NEW TASK Taskname
    DESTINATION IN GROUP Groupname
    In all currently available and active application servers:
    CALL FUNCTION Remotefunction STARTING NEW TASK Taskname
    DESTINATION IN GROUP DEFAULT
    Sequential Processing
    In the following cases, the system chooses sequential (non-parallel) processing:
    ●      In table RSADMIN, entry QUERY_MAX_WP_DIAG has value (column value) 1.
    ●      The entire query consists of one sub-access only.
    ●      The query is running in a batch process.
    ●      The query was started from the query monitor (transaction RSRT) using various debug options (for example, SQL query display, execution plan display). See, Dividing a MultiProvider Query into Sub-Queries.
    ●      The query requests non-cumulative key figures.
    ●      Insufficient dialog processes are available when the query is executed. These are required for parallel processing.
    ●      The query is configured for non-parallel processing.
    ●      You want to save the result of the query in a file or a table.
    In Release SAP NetWeaver 7.0, the system can efficiently manage the large intermediate results produced by parallel processing. In previous releases, the system terminated when it reached a particular intermediate result size and proceeded to read data sequentially. This is no longer the case. Therefore, the RSADMIN parameter that was used in previous releases for reading a MultiProvider sequentially is no longer used.

  • What is the difference between skewness and cardinlaity

    Can any one explain the difference between skewness and cardinlaity.
    Thanks

    cardinality means the distinct values in a column and skewness means how the data is spreaded according to those distinct values. Means Let say there are 100 rows in a table and the distinct values are 2 i.e. 1 and 0. This distinct values are the cardinality and in this case cardinality is low. Now let say out of 100 records there are 99 1s and 1 0s, or 50 1s and 50 0s, this shows how the data is spreaded and this is skewness.

  • Difference between textared and textfield.

    hi
    please any one can tell me what is difference between textarea and textfield.at what time to take textarea,when to take textfield.

    Textareas are generally intended for a single line of input (I use them for 255 or less). Textareas allow you to specify an input block for inputting text by setting the columns and rows of the area, and is generally used for much larger data fields.
    Hope this is what you are looking for.
