":1", ":2" variable refs in SQL on wire

I'm writing a tool to analyze Oracle SQL queries over the network and I've found out that some of the numerical variables being sent over the network are encoded with ":1", ":2" refernces, e.g.:
SELECT * FROM table WHERE x = :1 AND y = :2
Then :1 and :2 are encoded separately in the binary fields of the packet travelling on the wire.
Is that form of encoding documented anywhere?
Sorry if that's an obvious question but it's difficult to search for such an information as ":" is automatically stripped from search engine queries :)

This indicates that the application is using bind variables, which is a very good thing. If you google "bind variables" with Oracle, you'll get plenty of information on why they're so useful.
In a nutshell, applications want to be designed so that they parse a query once, bind different values, and execute the query multiple times. When an application does this, it tells the optimizer that it only needs to figure out how to execute queries like this once, it doesn't have to optimize the query thousands of times just because you've changed the value of x and/or y you're looking for. This is also far kinder on your shared pool, since Oracle only has to cache one query plan.

Hi
Can we assign value to a variable in PL/SQL Loops?
DECLARE
V_Num NUMBER;
BEGIN
LOOP
V_Num := 10;
DBMS_OUTPUT.put_line(V_num);
V_Num := V_Num - 1;
EXIT WHEN V_Num = 0;
END LOOP;
END;
In the above program, Can we assign V_num with a value 10????????

In the above program, Can we assign V_num with a value 10????????Yes; the example you posted does that.
When the loop starts, the value 10 is assigned to v_num. You should see that value displayed by the put_line statement.
After that, v_num is set to 10 - 1 = 9.
Next, the EXIT condition is evaluated. At this point, v_num is 9, not 0, so the loop runs again. V_num is set to 10 again, and the loop continues forever (or, in some versions, until the dbms_output buffer is filled and an error occurs.)

How to use presentaion variable in the SQL statement

Is there any special syntax to use a presentation variable in the SQL Statement?
I am setting a presentation variable (Fscl_Qtr_Var)in the dashboard prompt.
If i set the filter as ADD->VARIABLE->PRESENTATION, it shows the statement as 'Contract Request Fiscal Quarter is equal to / is in @{Fscl_Qtr_Var} '.
And this works fine but when i convert this to SQL, it returns
"Contract Request Date"."Contract Request Fiscal Quarter" = 'Fscl_Qtr_Var'
And this does not work.It is not being set to the value in the prompt.
I need to combine this condition with other conditions in the SQL Statement. Any help is appreciated. Thanks

Try this: '@{Fscl_Qtr_Var}'

Presentation Variable in the SQL default section in the dashboard prompt

Hi Gurus,
I have two prompts and two go buttons. First Go button is used to populate pv_category1 presentation variable.
category_column --> pv_category1--> 1st Prompt
Product_Column --> pv_product2 --> 2nd Prompt
I want to set the default for the 2nd Prompt depending on the 1st Prompt ( Category) chosen by the user.
In the SQL default --> i have typed in the below Query.
*Select TableName.Product_Column from Subject_Area where category_column = '@{pv_category1}'*
The Problem is that i dont get any default value for 2nd Prompt after choosing the First prompt and hitting the GO Button.
If i hardcode the value in @{pv_category1} ...
for eg
Select TableName.Product_Column from Subject_Area where category_column = 'Incidents' i get the corresponding value as default.
But i want this 2nd prompt (product) to dyamically default depending on the 1st prompt (category) chosen by the user.
I am using OBIEE 10.1.3.4 and i have googled a lot on this topic...
can we not use Presentation variable in the SQL default section of the Dashboard Prompt?
Any help in this regard would be highly appreciated.
Thanks
Ashish

Thanks for the Quick Reply.
But the functionality that i want to achieve is the default value in the 2nd column (out of many values for 2nd column) based on the 1st column chosen by the USER. for eg we have two columns in our database ie category and Product.. Data goes like this
category ProductName
Incidents --- A
Incidents --- B
Incidents --- C
Changes --- D
Changes --- E
Projects --- M
Projects --- N
Projects --- O
Projects --- P
If the User chooses Incidents in the first prompt then the default in the 2nd prompt should be B ( out of A,B,C Values available in the 2nd prompt)....
Checking the constraint checkbox doesnt solve the default problem...
Thanks

Problem returning variables from dynamic SQL/PLSQL

Hi, I have a problem I am trying to solve using a very short piece of dynamic SQL or PLSQL but I am having problems getting the variable values out of the dynamic block.
I have 16 counters whose names are made up of three variable parts - 'scheme', 'contributory category' and 'employment category'
The 'scheme' can be either 'no1', 'no2', 'off', 'cg' or 'amc'
The 'contributory category' can be either 'cont' or 'noncont'
The 'employment category' can be either 'ft' or 'pt'
(There are only 16 because only 16 combinations are possible)
For example the total counter name could be 'v_cg_noncont_ft_count'
I have created a variable by concatenating the various elements called v_incr_count_name which holds the name of the counter I want to increment.
I am running this whole thing within an anonymous PLSQL block so I cannot use global variables meaning that my variables are not visible within a dynamic PLSQL block.
I believe this means that either I need to bind the variables within a PLSQL block or use a SELECT FROM INTO SQL block.
I have tried a few solutions with no luck such as the following PLSQL:
v_incr_count := 'v_'||v_scheme||'_'||v_cont_cat||'_'||v_emp_cat||'_count';
sql_stmt := 'BEGIN :a := :a + 1; END;';
EXECUTE IMMEDIATE sql_stmt USING v_incr_count_name;
Unfortunately I am getting the 'IN bind variable bound to an OUT position' error which I believe is because it is trying to return a value into v_incr_count_name which has been defined by default as an IN variable. The problem is that I need to store the returned value into the variable whose name is stored in v_incr_count_name.
Another solution I tried is:
v_incr_count_name := 'v_'||v_scheme||'_'||v_cont_cat||'_'||v_emp_cat||'_count';
sql_stmt := 'SELECT '||v_incr_count_name||' + 1 FROM DUAL';
EXECUTE IMMEDIATE sql_stmt INTO v_return;
This solution gives me an 'Invalid colum error'
Any help would be greatly appreciated
Cheers, Dan

[[DataDirect][ODBC SQL Server Wire Protocol driver][Microsoft SQL Server]Column name or number of supplied values does not match table definition.]

Hii ..
need help on this ..
This what I am doing ..
I am using a DATAEXPORT function to export level0 data from my essbase 11.1.2.2 to Microsoft SQL 2008 tables.
So what I did first I exported the level0 data to a flat file using DATAEXPORT and the created the SQL columns by the same in that order only in my SQL table.
When I run it fails with this error:

Total Calc Elapsed Time for [test.csc] : [1.44] seconds
=============================================================
I did a simple test on my Sample.basic application then ..
loaded the calc data to it and then used the below script to export to a flat file
//ESS_LOCALE English_UnitedStates.Latin1@Binary
SET DATAEXPORTOPTIONS
                DataExportLevel "Level0";
                DataExportOverwriteFile ON;

            "Actual"
/*DATAEXPORT "File" "," "/home/hypadmin/samtest.txt";*/
DATAEXPORT "DSN" "Abhitest" "sample" "sa" "welcome1";
ENDFIX
out put as below:
"Sales"
"100-30","California"
"Jan","Actual",145
Now In sql I created only 3 columns with name Jan/Sales/Actual and when I run this script again with comments removed .. I get the same error as what I have got in my first test case with other application ..
but when I create the columns with same name as what its in export
Sales/100-30/Califirnia/Jan/Actual
It created the new rows successfully ..
So with this I think the error which I am getting with my other application might be because of the same column issue .. but then I have created all the columns by looking at the export file only as I did in sample ..
Any idea would be helpful ..
Thanks

First make sure you add
DataExportRelationalFile ON;
to your set commands it is missing
I alwats like to also add
DataExportColHeader dimensionName;
so I am sure what dimension is getting put into the columns.
Then count the number of dimensions in your outline (exclude attribute dimensions). You need at least that many columns in your table -1 + the number of members you will be returning as columns in the export
Taking your example Sample basic has 5 dimensions
Measures
Years
Scenario
Product
Market
Since you did not specify a dataexportcolheader it took the dense dimension Scenario as the columns. Your fix statement is limiting that to one member. Doing the math
5 -1 + 1 = 5 columns in your table which is what you found works. Suppose you fixed on bothe Actual and budget in scenario then you would need 6 columns 5 -1 +2

Using a number variable in an SQL statement

Hi,
I am trying to use a variable in an sql statement and I have run into problems when the variable is a number. The following line of code works if the variable is a string but not if it is a number.
"SELECT TOP 1 UUT_STATUS FROM UNIT_UUT_RESULT WHERE UnitID = '" + Locals.LocalUnitID + "' ORDER BY START_DATE_TIME DESC"
Is there a difference in the use of the single and double quotes and the + sign for number variables?
Thanks
Stuart
Solved!
Go to Solution.

Hi Stuart,
I am assuming that the UnitID is stored as a numeric in the database? If so, the proper SQL syntax for comparing with numerics should not use a single quote (or any quotes for that matter). The quotes are used only for strings.
So you would want to use:
"SELECT TOP 1 UUT_STATUS FROM UNIT_UUT_RESULT WHERE UnitID = " + Locals.LocalUnitID + " ORDER BY START_DATE_TIME DESC"
This is really more of an SQL question universal to all languages, not just TestStand.
Here is an excellent resource that you can consult:

How to pass a variable for a SQL query in OLEDB source?

Hi All,
I am new to SSIS and working on it past few days. Can anyone please help me getting through a scenario where I need to pass a variable in the SQL statement in OLEDB source connection. Please find below for the details.
eg:
1) I have a SQL table with the columns SerialNumber, Name, IsValid, FileName with multiple rows.
2) I have the file Name in a variable called Variable1.
3) I want to read the data from my SQL table filtering based on the FileName (Variable1) within a data flow task and pull that data to the destination table.
Question: In the data flow task, added source and destination DB connection with a script component in between to perform my validations. When trying to retrieve the data from source using the variable (i.e. SQL Query with variable), I am not able to add
the query as the SQL statement box is disabled. How to filter the data based on the variable in the source DB ?
Any help/suggestions would be of great help.
Thanks,
Sri

Just to add with Vaibhav comment .
SQL Command : SQL query either with SQL variable or any condition or simple Sql statement
Like ;
Select * from dimcustomer
SQL Command using Varible :
Sometimes we design our dynamic query in variable and directly use that variable name in oledb source.
If you Sql query needs a condition based on SSIS variable .
you can find a Example here :

EA3/EA2/EA1 - Bind Variables in PL/SQL

EA1 seems to have taken a backward step when it comes to supporting bind variables in PL/SQL.
Back in 1.1.3, according to the bugs fixed list, we apparently fixed bug 5884935 (BINDS IN A PL/SQL STATEMENT HAS "NOT ALL VARIABLES BOUND" ERROR), although this was only ever when running as scripts (as per Bind variables in PLSQL bug not fixed?
Now according to the 1.2 documentation, bind variables are not supported in the script runner (section 1.7.2) and the SQL*Plus variable command is not supported (section 1.7.1). However, I can run the following code "successfully" (no errors reported but the substitution text entered does not appear in the dbms_output):
variable bind_text varchar2(30);
declare
l_text varchar2(30);
begin
:bind_text := '&sub_text';
dbms_output.put_line('Bind text: "' || :bind_text || '"');
end;
Now in EA1, running this as a script results in "ORA-01006: bind variable does not exist"
Running the variable statement results in "ORA-00900: Invalid SQL Statement" and running the PL/SQL results in "ORA-1008: not all variables bound".
Can someone from the SQL Developer team please comment on the intended support for bind variables in PL/SQL?
Thanks,
theFurryOne

I know that the variable command isn't supported (as I said above), but that was also the case in 1.2, where it did actually sort of work.
I am not talking about local PL/SQL variables declared within the PL/SQL - I am trying to get user entered values into the PL/SQL in the same way as prompting for bind variable values in SQL.
So using SQL Developer bind variables inside PL/SQL is my end goal - preferably when running anonymous PL/SQL blocks as statements in the worksheet.
However, as there have been "fixed" bugs to enable bind variables in PL/SQL, which require the use of SQL Plus commands that are not supported in SQL Developer (ie variable), I am trying to work out what the development team think the intended support for bind variables in PL/SQL is. Then I will know if what I want needs to be reported as a bug or logged as an enhancement request.

Hi,
You have customers who are running distributed transactions using a gateway which need to be rolled back. However, the gateway has not been correctly configured for distributed transactions. To roll back a transaction on the SQL*Server database a connection is made as the user defined in the parameter HS_FDS_RECOVERY_ACCOUNT in the gateway init<sid>.ora file but this user has not been created in the SQL*Server database with the password defined in HS_FDS_RECOVERY_PWD. This user also needs to own the transaction log table.
I assume you are using the Database Gateway for SQL*Server (DG4MSQL) as the Database Gateway for ODBC (DG4ODBC) doesn't support distributed transaction.
If you have access to My Oracle Support have a look at this note -
How to Setup DG4MSQL to Use Distributed Transactions (Doc ID 227011.1)
Otherwise, check the Gateway documentation.

[DW 8.02 + PHP] how to use variables in advanced SQL queries

Hi all,
I can't find a way to use variables in an SQL query after
updating
dreamweaver 8.02.
I always get error messages that says: 'missing variable
type:myvariablename', undefined#myvariablename... and so on.
What is the correct way to use variables?
I usually set a variable in a PHP statement (example: <?
$today=date('Y-m-d'); ?>)
and then I compare this variable in the SQL query.
What is the correct syntax for variable in DW 8.02 in
advanced SQL
queries?
TIA

InterAKT released a new version of Kollection to cope with
