Storing SQL queries in database itself.

I want to store SQL queries in 9i database itself so that I just need to pass the parameters from VB.NET front end and the query will execute. How can I do this?

Possibly make use of Stored packages/procedures/functions?
Back in 97/98 I had worked with VB (version 6 at that time) application for which I had written stored procedures to do exactly that... (except for select) VB application would pass parameter values to these procedures for doing inserts/updates/deletes. No application user was given direct insert/update/delete privileges.
Also I had triggers written for each of the table involved to keep footprint (user id and date/time) for last update/insert for each of the row.
I don't remember for sure if the application deleted rows from the DB. I think the application handled delete by actually updating a flag (active/inactive) again with a foot print so that you can track back the "deletes".
my 1/2 cent worth of thought

Sql queries - slow database

hi all,
is there a general but specific way to generate a list of sql queries that are consuming most resources and resulting in slow database performance?
thanks.

There are very few ways in this world that are "general but specific".
You can use "general" tools like StatsPack and AWR.
You can write "general" queries on V$SQL, V$SQLAREA, V$SQLSTATS.
You can use "specific" methods like Tracing.
You can use "specific" methods like Client side (or Application Server side) Logs.

Problems storing sql statement in database

Hi,
I'm writing an application which needs to select a sql statement from an oracle database. The statement should look something like this:
"select id,name,... .from table 1 where id = " + ID + " and name = " + NAME
however when I select this from the database it give a sql error - invalid sql statement, I've tried putting it in the database without quotes, with single quotes etc but I can't seem to get it working.
I'd much appreciate it if any one had any ideas on this.
thanks.

debug it: output the sql string to a println or
JTextArea. See what is in it (and test it) . Must be a
null value in the variables.The variables are set previously in the code
I outputted the sql string to the screen but the variable names are not being replaced by the values.

How to use database control to execute sql queries which change at run time

Hi all,
I need to execute sql queries using database controls , where the sql changes
at run time
based on some condition. For eg. based on the condition , I can add some where
condition.
Eg. sql = select id,name from emp where id = ?.
based on some condition , I can add the following condition .
and location = ?.
Have anybody had this kind of situation.
thanks,
sathish

From the perspective of the database control, you've got two options:
1) use the sql: keyword to do parameter substitution. Your observation
about {foo} style sbustitution is correct -- this is like using a
PreparedStatement. To do substitution into the rest of the SQL
statement, you can use the {sql: foo} substitution syntax which was
undocumented in GA but is documented in SP2. Then, you can build up
the filter clause String yourself in a JPF / JWS / etc and pass it into
the DB control.
For example:
* @jc:sql statement="select * from product {sql: filter}"
public Product[] getProducts(String filter) throws SQLException;
This will substitute the String filter directly into the statement that
is executed. The filter string could be null, "", "WHERE ID=12345", etc.
2) you can use the DatabaseFilter object to build up a set of custom
sorts and filters and pass that object into the DB control method.
There have been other posts here about doing this, look for the subject
"DatabaseFilter example".
Hope that helps...

Hi Maruthi,
The parameter substituion , I guess is used like setting the values for

What I'm trying to do , is change the sql at run time based on some condition.
For example ,
consider the following query :
select col1,col2 from table t where t.col3 > 1
At run time , based on some condition , I need to add one more and condition.
i.e. select col1,col2 from table t where t.col3 > 1 and t.col4 < 10.
This MAY not address your issue but if you are trying to add "optional" parameters
you may try including ALL the possible parameters in the SQL but send in null
for those params that you don't want to filter on in any particular case. Then,
if you word your query
as follows:
select col1, col2 from table t where t.col3 > 1 and (t.col4 = {col4param} or
{col4param} is null) and (t.col5 = {col5param} or {col5param} is null) ...
you will get "dynamic" filters. In other words, col4 and col5 will only be
filtered if you send in non-null parameters for those arguments.
I have not tried this in a WL Workshop database control but I've used
this strategy dozens of times in stored procedures or jdbc prepared statements.
Good luck,
Dan

SQL Queries in Code V/s Stored Procedures

Hi Friend,
Can any one of you guide me with following..
What is faster ? using SQL Queries in Java code or using Stored Procedures which are called from code?
I understnd Stroed Procedures are faster and definitely it provides more maintainability.
If any one can give me any links or resources which outlines pros and cons of using Stored Proc and SQL Queries embedded in Java than it would be a great help..
If there are any articles which proves either of the above is a preferred way, that would also help..
Appreciate the effort in advance !!
Thanks
Gurudatt

Well one benefit of Stored Procs is that you "compile" it on the database whereas you might build your query on the fly in java... test coverage is important in order not to have such things as a typo in a column name....
Still, if you change a table, you have to go through all the procedures in SQL and likely to do so in some of your business object... and trust me, that can be hell!
It all depends on the use of the app...
From my experience, Stored procedure are much faster than built-on-the-fly SQL (and quite faster than prepared statements depending on the JDBC driver, the re-use of connections etc...)....
IMHO, you'd probably be wise to start of with prepared statements, and when the schema seems stable enough (ie unlikely to change), look for the slower queries and convert them to stroed procedures.
If you don't have to support several databases and are tight on performance, you can even include some logic in your stored procedure (e.g. update several tables, based on various selects...etc...). The language is usually quite powerful, and that can save you the run-time of selecting, converting to object , process and update (i.e. several roud-trip between DB and app)...
Tshcuss!

How to see what SQL queries are made to my Database Server?

Hi all,
I'm a newbie. I'd like to know if there's a way to find out what SQL queries are being made to my Database server at the server end.
Is it possible that Oracle Database Manager logs this information (including the exact query/SQL)somewhere in its logs? How to enable such an option and/or view the recent SQL queries made ?
Please enlighten me. Thanks in advance.
Thanks and Regards

"I checked the V$SQLTEXT view too. It has only 64 characters for SQL_TEXT field." Yes yes but you might have noticed that it also has the column called piece. The view shows the full SQL statement broken up into little pieces. Use ADDRESS and HASH_VALUE to link to v$sql. There is also a view V$SQLTEXT_WITH_NEWLINES that throws in some line separators to make it "easier" to read.
Example below shows full text of SQL statements currently executing.
SQL> column address noprint
SQL> column hash_value noprint
SQL> break on hash_value skip 1
SQL> select

Can I use Microsoft SQL Server Management Studio version 11.0 to write SQL queries for "SQL Server Compact 4.0 Local Database"

Hi, Can I use Microsoft SQL Server Management Studio version 11.0 to write SQL queries for "SQL Server Compact 4.0 Local Database" ?
When I use Connect Object Explorer, the "Connect to Server" dialog box which pops up has only 4 selections in the Server Type Drop Down List. They are Database Engine, Analysis Services, Reporting Services & Integration Services. I have read
somewhere that there should be a compact database option. but I do not see it.
What I would like to do is use free form SQL Queries against the tables in "SQL Server Compact 4.0 Local Database" .
Once I have validated these queries, then I will use them in my Visual Studio 2012 C#, ASP.NET application. I created the Local Database using Visual Studio 2012 for use by my application.
Thank you for your help..

Hello,
With SSMS 2005 we have had the Option to work with SQL CE database files, but not with higher Version of SSMS.
You can use the free SQL CE Toolbax instead; see

SQL queries from a Citadel database

We are retrieving data with third-party package SQL queries from a Citadel database. Certain queries for some object members will not return data, but the SQL search application software returns an "error". An analysis of the error from the SQL end does not find problem on SQL side. I suspect corruption of Citadel database. The link to database is good, as most tags do return a value as expected.
This problem occurred at the time of re-location of the database to a replacement computer. Any ideas on how to fix such a problem?

Can you give an example of the "bad" SQL statement and a good one?

Information on how to run SQL queries on the CUCM itself please

Good Day All,
I need to run an sql query on the CUCM to list all of my directory numbers, their partition, and their external mask values.
I came across this excerpt below earlier so I have a bit of an idea how to do it but iw would be great to see some other examples of sql queries.
Any assistance is most appreciated.
Also, is there a document somewhere to tell me how to run these queries?
Thanks in advance

Re: Is there a way of pulling a report off CM showing all phones that have diverts on?
Try if running this SQL query from the CLI helps you, it should list all DN's that have CFA enabled to VM or a DN:
run sql select dnorpattern,cfadestination,cfavoicemailenabled from CallForwardDynamic c, numplan n where c.fknumplan = n.pkid and (cfadestination != '' or cfavoicemailenabled ='t')

Hi Amanda
Basically it's standard SQL, so it wouldn't hurt to google 'informix select statements' and do a little reading to get the basics. There are millions of permutations of queries so it's a matter of understanding the syntax, and then applying that to the database in question. The only difference when running commands from the CLI are that:
- You prefix the standard informix SQL statement with 'run sql'
- You don't get any help from CUCM with the syntax, so you might be well advised to use something that understands SQL a little and colorises it as you type, and then paste the resulting commands into the CUCM SSH window. I use a text editor named JEdit, if you create a text file and save it as a file ending in .sql it will highlight your syntax.
- Other programs are available that do reasonable syntax highlighting (e.q. SquirrelSQL) that are designed for querying the DB directly, but you can't actually query directly against the DB for security reasons. You'd still have to copy/paste the commands.
Now... to understand the DB you'll need a reference describing all the tables etc. This is here:
http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_programming_reference_guides_list.html
Pick your version of CUCM and download the 'Data Definition' document.
A few notes on the command:
run sql : is just the CLI command that tells the shell to run the following text as SQL.
select : the SQL command to retrieve data
dnorpattern,cfadestination,cfavoicemailenabled : the column names to retrieve
callforwarddynamic c, numplan n : the names of two tables, and the abbreviations you want to refer to them as
where c.fknumplan = n.pkid : this tells SQL to return values from the two tables where these fields match up. In the data definition you'll see notes that c.fknumplan (i.e. the fknumplan column in the callforwarddynamic table, as noted by the c. prefix) refers to the PKID column in the numplan field. This is a very standard type of join in the CCM DB.
and (cfadestination != '' or cfavoicemailenabled ='t') : another clause, basically in this query we want to see only rows where cfadestination isn't blank or cfavoicefmailenabled is set to 't' for true).
Most tables are linked in one of two ways in this database:
- a column prefixed 'fk' refers to the pkid field (there is always only one pkid field per table) in the table following the 'fk' prefix. E.g. above fknumplan refers to the numplan table, pkid field. fkdevice would refer to the device table, pkid field.
- a column prefiex 'tk' refers usually to an enum table which is prefixed with 'type'. This is a table that maps the number value in the 'tk' field to a string. An example would be tkmodel - this represents the phone physical model type (e.g. 7962), and maps to a table called typemodel, and the 'enum' column in that table.

SQL queries against a database view from an external system?

Hi,
I have a question about Database views in se11.
Is it possible to create a database view and that do SQL queries against this view from an
external system, Not a SAP system?
Please, I need you help.
Best Regards
Annika

Hi Annika,
it is possible , yes... but depends on your database systems in the SAP source DB and the external DB
(easier if they are the same, i.e. both ORACLE) - check out with your BASIS team (they have to create something like a "database link" in the external DB system that you can use to access the tables in the SAP source).
In the external DB you sure can create a view on these "remote" tables.
We used this to pull data form SAP DB to another DB system (both ORACLE based).
But this is NOT supported by SAP , so be carefull. Below is the restriction for ORACLE (as well for other DB systems )
see SAP note 581312 "Oracle database: licensing restrictions"
As of point 3, it follows that direct access to the Oracle database is
only allowed for tools from the areas of system administration and
monitoring. If other software is used, the following actions, among
other things, are therefore forbidden at database level:
* Querying/changing/creating data in the database
* Using ODBC or other SAP external access methods
This means that additional application software is only allowed if this
accesses the database through SAP interfaces (for example, RFC, SAP J2EE
or BAPI).
I would say if you KNOW the tables involved (using valid WHERE conditions and joins )
and don't start queries from hell (ad-hoc type) wich can bring down your SAP system performance
you can try it.
But be warned...
good luck...
bye

Sql queries for this database schema

1) Patient—PatientID, Name, DOB
2) Doctor—DoctorID, Name, MedLicenseNumber, Phone
3) Medication—MedicationID, BrandName, GenericName
4) Prescription—PrescriptionID, Date, PatientID, PrescriberID, MedicationID
Specify the SQL queries to retrieve:
a) The prescription information along with patient name, DOB, medication brand name, and prescribing doctor name sorted by most recent date.
b) The most prescribed generic medication name

Looks like assignment question to me
a, seems to be a case of straight forward join among all the involved tables on common fields. Suggest you learn about joins and try it out yourself.
see below link
http://www.w3schools.com/sql/sql_join.asp
b, Have a look at GROUP BY. you need to apply group by and take medicine name which repeats maximum (ie largest count value)

Stored procedure which executes the sql queries

Hi This is Swathi,
I have 200 Queries which Gets the rowcounts Of sorce and target tables, so i want to develop a procedure which takes the sql queries one by one exicutes them and gives a report with results of 200 queries.
This is to test ETL mappings.
Please give me some idea to write it.
Thanks.

The best place to store the queries, and HOW to store them depends on your architecture and on how your application is being used.
Is this a single-user application on a user's pc? Or is your application located on an application server in the middle-tier?
The queries should be stored where they will be used. Your queries should be stored in the tier where your application code will reside. On the client PC for a single-user app, on the application server for a 3-tier app and incorporated into stored procedures/functions/packages if part of a database app.
If your application is totally external to the database (e.g. a reporting app) then it doesn't make sense for you to become part of the database architecture. An org isn't going to let you create objects in the database to store your queries when your queries are not part of the database application. That puts the burden on them to backup your objects, restore them for your and provide support to you and your application.
What format to store the queries in is a different issue. A major criteria is the type of queries you are using and how they are used. Many apps that query the database cannot just use hard-coded queries that are never modified. Users need to be able to provide parameters (e.g. name, ID, state, etc) to select just the data that they want.
That means the base query itself may not even be valid syntax but needs to have a WHERE clause added. Prepared statements and queries that use bind variables ('WHERE ID = ?') are typically used for these.
One method of storage is to use Java property files that use name=value pairs. Using property files makes it easy to use Java to find a query by name and load it for you. Then your code would have functionality to modify the query to provide the parameter 'bind' values and execute it.
There are also frameworks available for handling database related functionality. There is no need for you to write your own libraries for this. I suggest you locate a suitable framework to use.

Multiple SQL Queries in SAP BPC 5.1 EVMODIFY

Hi All,
We have multiple SQL Queries in Outlooksoft 4.2 which extracts data from Oracle source system with different set of selections and conditions and parameters. We were able to use multiple SQL Queries in Outlooksoft 4.2 using Transform Data Flow Task and paste parameters using evModify dynamic script task, where ever extract to source system is needed.
According to SAP BPC 5.1, all these multiple SQL Queries and extracts by passing parameters will be coded in EVMODIFY dynamic script editor.But, EVMODIFY dynamic script editor is not working with the sets of multiple SQL Queris.It's able to recognize and execute the first SQL Query, but not able to execute from the second SQL Query.
Does any body, did multiple extracts using SQL Queries to the source system by passing parameters using SAP BPC 5.1 data manager and SSIS Packages, please let me know, how you did achieve the above functionality.
