Using package constant in SQL

I am trying to use a package constant in a query as follows:
SELECT field1 FROM table t WHERE CEIL(sysdate - t.field2) > schema.package.constant
field1 is a name
field2 is a timestamp
constant is an integer indicating the expiration time in days
basically I am trying to find all expired items.
I get the error "ORA-06553: PLS-221: 'constant' is not a procedure or is undefined" on this query.
I use this same query as a cursor in the package itself with no errors.

Unfortunately you cannot directly use package global variables in select statements like this.
One workaround is to use bind variables for that:
<p>
SQL> CREATE OR REPLACE PACKAGE pkg
AS
   myconstant   VARCHAR (20) := 'This is my constant';
END pkg;
Package created.
SQL> VAR myconstant VARCHAR2 (20)
SQL> EXEC :myconstant := pkg.myconstant
PL/SQL procedure successfully completed.
SQL> SELECT :myconstant
FROM DUAL
:MYCONSTANT
This is my constant

How to use Java with PL/SQL commands to send an email with attachment

Apologizes in advance if this is the wrong place to ask the question.
I need to use Java with PL/SQL commands to send an email with attachment. My java application runs from the command line and does some magic to gather info from an Oracle 11g db. If the DB has sendmail configured, I'd like to send the results of the data gathering as an attachment to the email addresses. I'm not sure how to do this. I've been reading up on on PL/SQL can send email with UTL_SMTP - with attachments. I'm just not sure how to translate that into being triggered by my Java application. Any suggestions or pointers on what I should read would be appreciated.
Background - I've been programming in Java for 10+ years, but this is my first time using databases. I also have been on these forums for a long time, but lost my profile when it was switched to Oracle.
Thanks for all help.

user13726880 wrote:
The original requirements were put together and given to me, an Oracle newbie. They expected the Java app to use something intrinsic to Oracle and Unix sendmail. To solve my problem, I use a JDBC connection to run some SQL commands. I take that data, format it and send the results by email to the user. By default the requirement is to send it as an HTML attachment using Unix 'sendmail'. So I do that using Runtime exec. I have also added JavaMail functionality as an alternative to sendmail. It works great and as expected.Sounds like a reasonable solution.
Note however that PL/SQL itself can send email. And PL/SQL can call unix sendmail too.
However myself I would have done it in java with JavaMail.

How to use Image field in SQL-7 for curvs

I sampling data from a NI-card. There will be a lot of data so I thought I should use Image-field in SQL-7 to save the hole curve. How do you do that?

I would suggest looking into the Database Connectivity Toolset. It has complete SQL functionality and uses ADO to connect to many types of databases. I have it and it comes with example programs which demonstrate how to write to and read from databases using SQL.

How to use parameters in oracle SQL script????

Right now I am writing a SQL script to create a schema and build the objects of this schema....
I use a .net winform program to run sqlplus to parse this sql script ...
The problem is that the schema name and the tablespace's location and the sys password must be input by the user, so my SQL script should use these runtime input parameters instead of const parameters....
So, how to use parameter in SQL script ...........
Are there some example scripts in oracle home directory for me to refer to????

Hi,
UNISTD wrote:
thanks .....
what's the difference between variable , define, accept in sqlplus ???VARIABLE declares (but does not assign a value to) a bind variable. Unlike substitution variables, bind variables are passed to the back end to be compiled, and they can only be values in certain data types. You can not use a bind vaiable in place of an identifier, so to do something like
CREATE USER &1 ...a bind variable won't work.
"DEFINE x = y" sets the substitution variable &x to have the value y. There is no user interaction (unless x or y happen to contain undefined substtiution variables).
"DEFINE x" shiows the value of the substitution variable &x, or, if it is undefined, raises a SQL*Plus error. I use this feature below.
ACCEPT sets a substitution variable with user interaction.
And if the user miss some parameters in “sqlplus /nolog ssss.sql par1 par2 par5 par6”, how to use default value of the miss parameters??Don't you need a @ befiore the script name, e.g.
sqlplus /nolog @ssss.sql par1 par2 par5 par6Sorry, I don't know of any good way to use default values.
The foloowing works, but, as you can see, it's ugly.
"DEFINE 1" display a message like
DEFINE 1            = "par1" (CHAR)if &1 is defined; otherwise,it will display a SQL*Plus error message like
SP2-035: symbol 1 is UNDEFINEDNotice that the former contains an '=' sign, but the latter does not.
The best way I know to use default values is to run the DEFINE command, save the output to a filee, read the file, and see if it's an error message or not.
So you can use a script like this:
--     This is DEFINE_DEFAULT.SQL
SPOOL     got_define_txt.sql
DEFINE     &dd_old
SPOOL     OFF
COLUMN     dd_new_col     NEW_VALUE     &dd_new
WITH     got_define_txt     AS
     SELECT q'[
          @got_define_txt
]'               AS define_txt
     FROM    dual
SELECT     CASE
         WHEN define_txt LIKE '%=%'
         THEN REGEXP_REPLACE ( define_txt
                           , '.+"
([^"]*)
                     , '\1'
         ELSE '&dd_default'
     END        AS dd_new_col
FROM     got_define_txt
{code}
and start your real script, ssss.sql, something like this:
{code}
DEFINE          dd_new     = sv1
DEFINE          dd_old     = 1
DEFINE          dd_default     = FOO
@DEFINE_DEFAULT
DEFINE          dd_new     = sv2
DEFINE          dd_old     = 2
DEFINE          dd_default     = "Testing spaces in value"
@DEFINE_DEFAULT
{code}
when this finishes running, the substitution variable &sv1 will either have the value you passed in &1 or, if you didn't pass anything, the default value you specified, that is FOO.
Likewise, &sw2 will have the value you passed, or, if you didn't pass anything, the 23-character string 'Testing spaces in value'.
Here's how it works:
Define_default.sql puts the output of the "DEFINE x" command into a column, define_txt, in a query. That query displays either the existing value of the substitution variable indicated by &dd_old or, if it is undefined, the default value you want to use, which is stored in the substitution variable &dd_default. The substitution variable named in &dd_new is always set to something, but that something may be its existing value.
Notice that the paramerters to define_default.sql must be passed as global varibales.
Why didn't I just use arguments, so that we could simply say:
{code}
@DEFINE_DEFAULT sv1 1 FOO
{code}
? Because that would set the substitution variables &1, &2 and &3, which are miost likely the very ones in which you're interested.
I repeat: there must be a better way, but I'm sorry, I don't know what it is.
I usually don't do the method above. Instead, I always pass the required number of parameters, but I pass dummy or plce-holder values.
For example, if I wanted to call ssss.sql, but use defulat vlaues for &1 and &3, then I would say something like:
{code}
@ssss ? par2 ?
{code}
and, inside ssss.sql, test to see if the values are the place holder '?', and, if so, replace them with some real default value. The use has to remember what the special place holder-value is, but does not need to know anything more, and only ssss.sql itself needs to change if the default values change.

[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
the 8.0.2
changes. AFAIK, you should be able to download the updated
version from
your InterAKT account area.

How to use sets in PL/SQL

Hi all,
I want to know how to implement algebraic sets in PL/SQl.
I mean for example if there is a table R(A,B) where A is aprimary key having the data :-
{(1,2),(2,1),(2,3),(3,1)}
i want to have a data type that represents sets of data corresponding to attribute B.
i.e the data type should have the value {1,2,3}
Thanks.

Not sure that I understand correctly.. and how you want to fit PL/SQL into this.
Sets are best handles as Oracle tables. The best language to deal with sets are SQL. So to get the results you want should be a simple:
SELECT DISTINCT b FROM table_r ORDER BY 1
The results of this can be a cursor that needs to be stepped (fetch) through.
The results can be bulk collected into a dynamic array, e.g.
create or replace type TArray is table of number;
And then in PL/SQL:declare
array TArray;
begin
SELECT DISTINCT b BULK COLLECT INTO array FROM table_r ORDER BY 1;
end;The array object will now contain TArray(1,2,3).

How to use hints in PL/SQL

Hi,
If I want to use hints in PL/SQL procedure, it is valid to write it this way:
begin
update /*+ INDEX(opp DIM_OPP_REFDB_IDX) */
scott.rec_dim_opportunity opp
set opp.mp_opportunity_re ....
endI doubt when I tried it that the optimizer didn't actually use the index.
Thanks in advance.
Oracle 10g R1
Windows 2003 32-bit

the table is of 90MB and when the UPDATE statement is used in SQL, the explain plan output shows that the index is used.
When I execute it from a procedure, the Current Statement show in TOAD doesn't show that the index is used and the update takes forever. Explain plan of the statement (as show in TOAD) shows that full table scan is being used.

How to use the EBS PL/SQL API from outside PL/SQL

Hi,
our attempts to call the stored procedures/functions of the EBS PL/SQL API via JDBC revealed the following issues:
1. Logical values cannot be exchanged through boolean parameters as the OCI has no notion of this type. Instead we need to write PL/SQL wrappers converting boolean to integer and vice versa. Is that true or are we missing something?
2. Complex values cannot be exchanged through record types as only PL/SQL code has a notion of this type. Instead we need to write PL/SQL wrappers converting record values to object type values. Is that true or are we missing something?
3. Types must be defined outside of packages, i.e. in the schema, for whatever reason. Instead we need to write PL/SQL wrappers converting values of types defined in packages to values of types defined in the schema. Is that true or are we missing something?
4. It is possible to let functions return tables so the results can be queried using SELECT * FROM TABLE. Such functions are called "table functions". Is there something similar for the other direction, i.e. is it possible to call a stored procedure and pass in a table value through an sql INSERT statement?
5. Do we really have to write all those wrapper routines on our own or is there a PL/SQL library providing such? If not, is there some kind of code generation facility that can generate such wrappers?
Thanks and Regards,
Konrad

Hi Helios,
I belive its better to move your issue on Forum Home » Database » SQL and PL/SQL which you can get more quick responseYou are probably right! I was thinking about a different forum but I did not see this one. I just posted the question there...
Still, if somebody has an idea here as well, just let me know ;-)
