Crystal view table or SQL view table

In Crystal and SQL there have lot of View tables. What kind of table called View table? What's the difference with tables without view prefix?
I think view tables are few tables linked together for designers to use instead need to link few tables by themselves.
How to create view table and the purpose using view tables?

Hi,
A view tables is, in essence, a virtual table. It does not physically exist. Rather, it is created by a query joining one or more tables.

You can search on the web for more samples.

How to provide joins between oracle tables and sql server tables

Hi,
I have a requirement that i need to generate a report form two different data base. i.e Oracle and Sql Server.

Heterogeneous joins do not exactly scale and performance can be severely degraded by network speed and b/w availability. And there is nothing you can do in the application and database layers to address performance issue at the network level in this case - your code's performance is simply at the mercy of network performance. With a single glaring fact - network performance is continually degrading. All the time. Always. Until it is upgraded. When the performance degradation starts all over again.
If the tables are not small (few 1000 rows each) and row volumes static, I would not consider doing a heterogeneous join. Instead I would rather go for a materialised view on the Oracle side, use a proper table and index structure, and do a local database join.

Create material Master by connecting SAP Tables to SQL server tables

We would like to use data in SQL server tables to upload material master into ECC. We have a number of rules embedded into the SQL server tables and would like that the LSMW program should pick up records directly from the SQL table without passing through a flat file format. Can anyone guide us how to accomplish this. We are on SAP AFS ECC 5.0 Thanks in advance

Is anyone having any ideas on this ...?

Problem to run the Crystal report inside from SAP B1 based on SQL views.

Hello,
I have a problem to run my Crystal report inside from SAP B1 which is based on SQL views.And the SQL views are stored in a separate database in SQL server.The error which i am getting is saying the the tablename does not exist.What i need to do in order to sort this problem.
Great if somebody can help me to sort out this so that i can run my report based on SQL views stored on separate database other than SAP databases inside from SAP B1.

Try using a SQL synonym in your company database for the views outside the company database. I don't know if SBO will let you get away with it, but its worth a shot.
If your company database is MyCompany and you have a view called MyView in Views database, assuming the view belongs to schema dbo, and you want the synonym to belong to dbo schema in your company database, run this:
Use MyCompany
go
create synonym dbo.OutsiderView for
Views.dbo.MyView
go
select * from OutsiderView
The select statement should return the contents of MyView in the Views database while you are connected to your MyCompany database.
For more info, see the Books Online for MSSQL on topic synonym.
You will need to change your CR options to include displaying synonyms along with tables, views, etc. You may also need to grant select to B1 users.

Table compression and alter table statement

Friends
I am trying to add columns to a table which is compressed. Since Oracle treats compressed tables as Object tables, I cannot add columns directly so I tried to uncompress table first and then add columns. This doesnt seems to work.
What could be issue.
Thanks
Vishal V.
Script to test is here and results are below.
-- Test1 => add columns to uncompressed table -> Success
DROP TABLE TAB_COMP;
CREATE TABLE TAB_COMP(ID NUMBER) NOCOMPRESS;
ALTER TABLE TAB_COMP ADD (NAME VARCHAR2(10));

Reports based on SQL view contain no data. Reports based on tables work just fine

When we load a report into Crystal reports server that is based on a SQL view the report will run but will contain no data. A report that pulls data from SQL tables works just fine. Running the crystal report on standalone crystal reports works just fine.
I am completely lost on this one. If you have any ideas please send them my way.

Are you missing an ODBC / TNS entry on your CMS (or report processing, if clustered env) server? This could definately be an issue if the report will run locally within CR client, but not when hosted on the enterprise environment. Another test would be to run the report from CR client ON the CRS / BOE server..

Can't view tables in SQL database

Hi,
I'm using DW CS4 to connect to SQL server 2005. I can connect to my database, but when I try to create a recordset, the only tables I can view or select is everything in the System Tables and System Views - not the tables that I actually want to select.
e.g.
dbo.dtproperties
INFORMATION_SCHEMA.CHECK_CONSTRAINTS
INFORMATION_SCHEMA.COLUMN_DOMAIN_USAGE
etc.
I guess this is to do with administering SQL server but even going through SQL server documentation online I can't seem to figure it out. Is it to do with Views and/or schemas in SQL server management studio? Please help!

Have you connected to the database using SQL Server Management Studio and looked at the tables and fields to be sure all is in order?

I need the "Real" Table / Table Column names from a sql view

Firstly, we have a system with ~1000 tables and ~250 views. We have field level security on the table columns (in our code)
Now we have a lot of views which select data from the tables, but I need to get the "Table Column Name" that is linked in the view.
I know there are view columns that is not linked to a specific table column, (or concatenation of columns) so those columns can just return NULL.
From the sample you will see there is a view selecting data from another view. I know it is not the best sql performance (execution path) but that is another topic on its own.
I went through a lot of the sys.* stored procs or sys.* views to try and figure out if there is a view that we can use to get the expected results.
here is the sql code:
if

sys.all_objects

drop view dbo.AliasView1

Exists (select

Now we have a lot of views which select data from the tables, but I need to get the "Table Column Name" that is linked in the view.
If you are using SQL Server 2012/2014, then you can use
sys.dm_exec_describe_first_result_set (Transact-SQL) to gte the informations.

Using SQL view object to create ADF table

Hi,
I have created a column called "Month" (which extracts month from the date column) and another column to count the no. of requests.
i want to create an ADF table with 2 columns, a column showing the month and another is showing the no. of requests for that month.
However, now I only managed to achieve the ADF table to show the overall total requests, which means if i add up all the requests for all the months and i get 500
My ADF table shows this:
Jan: 500
Feb: 500
Mar: 500
How should I create the view or what should I do to make it such that the no. of request is based on the month?
Please advice.
Thanks (:

Hi,
For the given situation you can create a Query Based View Object with the following query
SELECT
COUNT(TEMP1.DT) REQUEST,
TO_CHAR(TEMP1.DT, 'Mon') MONTH
FROM
TEMP1
GROUP BY
TO_CHAR(TEMP1.DT, 'Mon')
where DT is the date column and temp1 is the name of the database table.
Following are the steps that i followed to get this query :
i have taken the following sample table :
create table temp1
(srno number primary key,
dt date)
*Note you may use any existing column instead of srno or use dt only (i took an extra column as u know we need a primary key /row id)
the following is the sample data
insert into temp1 values (1,sysdate);
insert into temp1 values (2,sysdate);
insert into temp1 values (3,add_months(sysdate,1));
insert into temp1 values (4,add_months(sysdate,1));
insert into temp1 values (5,add_months(sysdate,3));
insert into temp1 values (6,add_months(sysdate,5));
the table appears as follows
SRNO DT
1 22-JUN-12
2 22-JUN-12
3 22-JUL-12
4 22-JUL-12
5 22-SEP-12
6 22-NOV-12
To start with ADF View Object Creation (Using Jdeveloper 11.1.2):
Create the view object using Create View Object wizard
In Step 1. Name window
set the value for Name : Viewab (you can use any of ur choice)
In the data source section : select query
In Step 2. Query window
a. Click Query builder (it will pop up sql statment window)
b. In the SQL Statement window
in quick-pick objects section -> select temp1 table -> shuttle the columns from available list to selected list
in select clause section -> select srno column from select list-> choose count() function from function drop down list -> insert function -> set alias to REQUEST-> click validate
now select dt column from select list -> choose to_char() function -> click insert function -> alter the function to to_Char(temp1.DT,'Mon') -> set alias to Month -> click validate
in the group by clause section -> Click the green symbol to add -> from the expression palette insert dt column -> insert the to_char function -> alter the function to to_char(temp1.DT,'Mon') -> click validate
in the Entire SQL Query section -> click test query -> in the test query window -> click query result-> you will see the result -> click close -> click ok
Click next
Step 3: Bind Variables
Click Next
Step 4: Attribute Mappings
click Finish
So the view object is ready :)

ORA-02070: Error when updating a SQL Server table thru an Oracle View

I have a SQL Server table TIMESHEET which contains a number of VARCHAR and NUMERIC columns plus a DATETIME column.
Only the DATETIME column is giving me trouble.
On the ORACLE side I have a view which selects from the SQL Server table but in order to get the SELECT to work, I had to either put a CAST or TO_DATE function call around the DATETIME field
Below is the relevant part of the 2 view definitions I have tried
create view TIMESHEET as
SELECT
"TsKeySeq" as TS_KEY_SEQ,
"EmployeeNo" as EMPLOYEE_NO,
CAST("PeriodEnding" AS DATE) as PERIOD_ENDING,
. . . (more columns - not relevant)
FROM [email protected];
An update to the view generates this message
ORA-02070: database OLEMSQLPSANTDAS6 does not support CAST in this context
create view TIMESHEET as
SELECT
"TsKeySeq" as TS_KEY_SEQ,
"EmployeeNo" as EMPLOYEE_NO,
TO_DATE("PeriodEnding") as PERIOD_ENDING,
. . . (more columns - not relevant)
FROM [email protected];
An update to the view generates this message
ORA-02070: database OLEMSQLPSANTDAS6 does not support TO_DATE in this context
If I don't include either the TO_DATE() or CAST() then I get
Select Error: ORA-28527: Heterogeneous Services datatype mapping error
ORA-02063:preceding line from OLEMSQLSANTDAS6
Does anyone have any idea how to update a SQL Server DATETIME column thru an ORACLE view?

You can't cast accross heterogenious databases and there is no need to. HSODBC treats SQL Server DATETIME column as DATE. For example, I have SQL Server table:
CREATE TABLE [Ops].[T_JobType](
     [JobType] [varchar](50) NOT NULL,
     [JobDesc] [varchar](200) NULL,
     [InsertDt] [datetime] NOT NULL CONSTRAINT [InsertDt_00000006] DEFAULT (getdate()),
     [InsertBy] [varchar](128) NOT NULL CONSTRAINT [InsertBy_00000006] DEFAULT (user_name()),
     [LastUpdated] [datetime] NOT NULL CONSTRAINT [LastUpdated_00000006] DEFAULT (getdate()),
     [LastUpdatedBy] [varchar](128) NOT NULL CONSTRAINT [LastUpdatedBy_00000006] DEFAULT (user_name()),
CONSTRAINT [T_JobType_PK] PRIMARY KEY CLUSTERED
     [JobType] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 100) ON [DATA01FG]
) ON [DATA01FG]Now on Oracle side I do:

Inconsistent SQL results when using View with UNION-ALL and table function

Can any of you please execute the below scripts and check the output. In the table type variable, I am adding 4 distinct object ids, where as in the result, I get only the row pertaining to last id in the table type variable. Same row is returned 4 times (4= number of values in the table type).
This scenario is occurring in our product with a SQL with exactly same pattern. I could simulate the same issue with the sample script I have provided.

Materialized views are showing up under Tables in SQL developer 2.1.0.63

Please,
Is there any setting to not display materialized view objects under the Tables in sql developer 2.1.0.63 ?
This was not happening in previous versions.
Thanks.

Yes, right-click the Tables node, Apply Filter, select Exclude MVs in the listbox.
Have fun,
K.

Problem occured when create a tree table for master-detail view objects using SQL queries?

I am programming a tree table for master-detail view objects using SQL queries and these 2 view objects are not simple singel tables queries, and 2 complex SQL are prepared for master and view objects. see below:
1. Master View object (key attribute is SourceBlock and some varaible bindings are used for this view object.)
SELECT cntr_list.SOURCE_BLOCK,
        sum(
         case when cntr_list.cntr_size_q = '20'
              then cntr_list.cntr_qty
              else 0 end ) as cntr20 ,
        sum(
         case when cntr_list.cntr_size_q = '40'
              then cntr_list.cntr_qty
              else 0 end ) as cntr40 ,
         sum(
         case when cntr_list.cntr_size_q = '45'
              then cntr_list.cntr_qty
              else 0 end ) as cntr45
FROM (
    SELECT yb1.BLOCK_M as SOURCE_BLOCK,
           scn.CNTR_SIZE_Q,
           count(scn.CNTR_SIZE_Q) AS cntr_qty
    FROM SHIFT_CMR scm, SHIFT_CNTR scn, YARD_BLOCK yb1, YARD_BLOCK yb2
    WHERE
    scm.cmr_n = scn.cmr_n
    AND (scm.plan_start_dt BETWEEN to_date(:DateFrom,'YYYY/MM/DD HH24:MI:SS') AND to_date(:DateTo,'YYYY/MM/DD HH24:MI:SS')
    OR scm.plan_end_dt BETWEEN to_date(:DateFrom,'YYYY/MM/DD HH24:MI:SS') AND to_date(:DateTo,'YYYY/MM/DD HH24:MI:SS'))
    AND scm.shift_mode_c = :ShiftModeCode
    AND scm.end_terminal_c = :TerminalCode
    AND scm.start_terminal_c = yb1.terminal_c
    AND scm.start_block_n = yb1.block_n
    AND substr(scn.start_location_c,(instr(scn.start_location_c,',',1,5)+1),instr(scn.start_location_c,',',1,6)-(instr(scn.start_location_c,',',1,5)+1)) BETWEEN yb1.slot_from_n AND yb1.slot_to_n

    AND scn.status_c not in (1, 11)
    AND scn.shift_type_c = 'V'
    AND scn.source_c = 'S'
    GROUP BY yb1.BLOCK_M, scn.CNTR_SIZE_Q
) cntr_list
GROUP BY cntr_list.SOURCE_BLOCK
2. Detail View object (key attributes are SourceBlock and EndBlock and same varaible bindings are used for this view object.)
SELECT cntr_list.SOURCE_BLOCK, cntr_list.END_BLOCK,
        sum(
         case when cntr_list.cntr_size_q = '20'
              then cntr_list.cntr_qty
              else 0 end ) as cntr20 ,

              then cntr_list.cntr_qty
              else 0 end ) as cntr40 ,
         sum(
         case when cntr_list.cntr_size_q = '45'
              then cntr_list.cntr_qty
              else 0 end ) as cntr45
FROM (
    SELECT yb1.BLOCK_M as SOURCE_BLOCK,
           yb2.BLOCK_M as END_BLOCK,
           scn.CNTR_SIZE_Q,
           count(scn.CNTR_SIZE_Q) AS cntr_qty
    FROM SHIFT_CMR scm, SHIFT_CNTR scn, YARD_BLOCK yb1, YARD_BLOCK yb2
    WHERE
    scm.cmr_n = scn.cmr_n
    AND (scm.plan_start_dt BETWEEN to_date(:DateFrom,'YYYY/MM/DD HH24:MI:SS') AND to_date(:DateTo,'YYYY/MM/DD HH24:MI:SS')
    OR scm.plan_end_dt BETWEEN to_date(:DateFrom,'YYYY/MM/DD HH24:MI:SS') AND to_date(:DateTo,'YYYY/MM/DD HH24:MI:SS'))
    AND scm.shift_mode_c = :ShiftModeCode
    AND scm.end_terminal_c = :TerminalCode
    AND scm.start_terminal_c = yb1.terminal_c
    AND scm.start_block_n = yb1.block_n
    AND substr(scn.start_location_c,(instr(scn.start_location_c,',',1,5)+1),instr(scn.start_location_c,',',1,6)-(instr(scn.start_location_c,',',1,5)+1)) BETWEEN yb1.slot_from_n AND yb1.slot_to_n

    AND scn.status_c not in (1, 11)
    AND scn.shift_type_c = 'V'
    AND scn.source_c = 'S'
    GROUP BY yb1.BLOCK_M, yb2.BLOCK_M, scn.CNTR_SIZE_Q
) cntr_list
GROUP BY cntr_list.SOURCE_BLOCK, cntr_list.END_BLOCK
3. I create a view link to create master-detail relationship for these 2 view objects.
masterview.SourceBlock (1)->detailview.SourceBlock (*).
4. I create a tree table using these 2 view objects with master-detail relationship.
When I set default value for variable bindings of these 2 view objects and the matching records exist, tree table can work well. I can expand the master row to display detail row in UI.
But I need to pass in dymamic parameter value for variable bindings of these 2 view objects, tree table cannnot work again. when I expand the master row and no detail row are displayed in UI.
I am sure that I pass in correct parameter value for master/detail view objects and matching records exist.
Managed Bean:
        DCIteratorBinding dc = (DCIteratorBinding)evaluteEL("#{bindings.MasterView1Iterator}");
        ViewObject vo = dc.getViewObject();
        System.out.println("Before MasterView1Iterator vo.getEstimatedRowCount()="+ vo.getEstimatedRowCount());
        System.out.println("Before MasterView1Iterator ShiftModeCode="+ vo.ensureVariableManager().getVariableValue("ShiftModeCode"));
        vo.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
        vo.ensureVariableManager().setVariableValue("DateTo", dateTo);
        vo.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
        vo.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
        vo.executeQuery();
        System.out.println("MasterView1Iterator vo.getEstimatedRowCount()="+ vo.getEstimatedRowCount());
        DCIteratorBinding dc1 = (DCIteratorBinding)evaluteEL("#{bindings.DetailView1Iterator}");
        ViewObject vo1 = dc1.getViewObject();
        System.out.println("Before DetailView1Iterator vo1.getEstimatedRowCount()="+ vo1.getEstimatedRowCount());
        System.out.println("Before DetailView1Iterator ShiftModeCode="+ vo1.ensureVariableManager().getVariableValue("ShiftModeCode"));
        vo1.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
        vo1.ensureVariableManager().setVariableValue("DateTo", dateTo);
        vo1.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
        vo1.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
        vo1.executeQuery();
        System.out.println("after DetailView1Iterator vo1.getEstimatedRowCount()="+ vo1.getEstimatedRowCount());
5. What's wrong in my implementation? I don't have no problem to implement such a tree table if using simple master-detail tables view object, but now I have to use such 2 view objects using complex SQL for my requirement and variable bindings are necessary for detail view object although I also think a bit strange by myself.

Hi Frank,
Thank you and it can work.
public void setLowHighSalaryRangeForDetailEmployeesAccessorViewObject(Number lowSalary,
                                                                          Number highSalary) {
        Row r = getCurrentRow();
        if (r != null) {
            RowSet rs = (RowSet)r.getAttribute("EmpView");
            if (rs != null) {
                ViewObject accessorVO = rs.getViewObject();
                accessorVO.setNamedWhereClauseParam("LowSalary", lowSalary);
                accessorVO.setNamedWhereClauseParam("HighSalary", highSalary);
            executeQuery();
but I have a quesiton in this way. in code snippet, it is first getting current row of current master VO to determine if update variables value of detail VO. in my case, current row is possibly null after executeQuery() of master VO and I have to change current row manually like below.
any idea?
            DCIteratorBinding dc = (DCIteratorBinding)ADFUtil.evaluateEL("#{bindings.SSForecastSourceBlockView1Iterator}");
            ViewObject vo = dc.getViewObject();
            vo.ensureVariableManager().setVariableValue("DateFrom", dateFrom);
            vo.ensureVariableManager().setVariableValue("DateTo", dateTo);
            vo.ensureVariableManager().setVariableValue("ShiftModeCode", shiftModeC);
            vo.ensureVariableManager().setVariableValue("TerminalCode", terminalCode);
            vo.executeQuery();
            vo.setCurrentRowAtRangeIndex(0);
            ((SSForecastSourceBlockViewImpl)vo).synchornizeAccessorVOVariableValues();

Developing database views between Oracle and SQL Server tables

I am on Oracle 10.2, my organization has many SQL Server databases as well and has now made
SQL server as company standard so many new databases will be developed in SQL Server. It is of course
not possible to convert all Oracle databases to SQL Server, so a mix environment will exist. Two questions:
1. Is it possible to develop database views in Oracle (10g in my case) which join Oracle tables with tables in SQL Server 2008? If yes, how. I have seen some heterogeneous connectivity setup to connect SQL Server to Oracle, but not sure whether it is possible to develop a database view across two databases.
2. I know it is not a SQL Server forum, but many DBA’s know both Oracle and SQL Server. Is it possible to develop views in SQL Server (SQL Server 2008 R2 in my case) which join Oracle 10g and SQL Server 2008 tables? I know in SQL Server, there is way to set up linked servers, but do not know whether it is possible to develop views.
Thanks a lot for your insight.

You can create views that join local Oracle tables and remote SQL Server tables. I'm pretty sure you can do the reverse as well but I haven't personally done it.
However, I would be very concerned about the performance you'd get if you created that sort of view. You'd very frequently end up in a situation where Oracle has to pull all the data in the remote table across the database link in order to apply predicates and join the data locally. That could be disastrous from a performance standpoint.
