Can I execute a statement in a string format?

Is it possible to create a statement in string format and then execute it in, for example, a method?

Depends on what you want to do... if you want to do something like eval("java.lang.System.out.println(\"foo\");"); it is possible - just parse the string and use reflection - but it get's very complicated after that.
If you are after mathematical expression parsers, JEP is one of the best: http://jep.sourceforge.net

System.out.println(lFdate+" "+lTdate+" "+lLdate);
i am getting the values from request parameters at that time it is giving values.
after convertion of string to date it is giving the null value what is wrong in this code

It might have thrown an exception. Try printing the stack trace in the catch block.

For just executing a method or two, reflection might be easier than beanshell (or it might not). For executing entire scripts, beanshell will be preferable over reflection.
(I assume beanshell uses reflection under the hood, but I've never bothered to peek.)

What can be the cause of Web ADI error : Cannot execute SQL statement?

I created a custom integrator in r12.2.3 and while loading I encountered an error, Cannot execute SQL statement.
I checked my setup in Interface attribute , the RUN_ID column has a default type SQL QUERY with a default value SELECT XXCONV_EAM_ASSET_NUM_S.NEXTVAL FROM DUAL.
If I have a right setup here, what can be the cause of this error?

Hi,
The possibilities can be of various reasons, with the sql statements,
xml descriptors, data sources, improper drivers anything. To crack down
the solution, kindly let me know the error messages and what exactly are

Execute commands/statements in txt file supplied to plsql procedure

Hi,
I need to execute commands which are in txt file , this txt filepath is supplied to the procedure.
In the procedure i want to open the txt file and read the commands and run the commands.
Please help on this .

The fact that you are supplying a file path (more correctly known as a directory) is going to be your first problem. Security within Oracle means that access to files on the file server require a directory object to be specified and these directory objects refer to a specific directory on the file server. If you're going to be passing different directories into your procedure then you're going to have to have different directory objects set up for all the possible directories that can be accessed (or issue dynamic DDL to redefine a known directory object each time).
Once you've done that you can use the UTL_FILE package (http://docs.oracle.com/cd/E11882_01/appdev.112/e25788/u_file.htm#ARPLS70906) to read the contents of the file as lines.
Then it depends what you mean by "commands" and "statements". Are you referring to operating system commands?... If so you will need to use something like the DBMS_SCHEDULER package to issue a job to run immediately with the appropriate command, as that is able to issue operating system commands, or you are going to have to write some Java code to issue commands for you (plenty of examples if you google). OR, perhaps you are referring to SQL statements? These could possibly be issued using the PL/SQL execute immediate statement, but you will be leaving your database open to SQL injection and major security issues, something that most companies would consider a serious flaw and not want.
how to read string which is delimited by ';'. or how read each charater in a file ..About time you read the documentation (http://tahiti.oracle.com/). There are functions: SUBSTR and INSTR which can search for things in strings and extract parts of strings, or you can use the more advanced regular expression versions of those REGEXP_SUBSTR and REGEXP_INSTR, or even REGEXP_REPLACE (which is also good for extracting parts of strings).

Execute DDL statements from pl / sql

Hi !!!!
I have to create every object (tables, sequences, etc) using a pl / sql block, so I need first looking for the object in the data dictionary and if it doesn't exist execute a ddl statement to create it.
I wanted to execute at the same "execute immediate " :
- create table.
- create synonym for the table created before.
- comments on table
- comments on table's columns
- grants on the table.
But I found some errors:
- I can`t have semicolon after every statement so I get an "ORA-00911: invalid character". I did'nt try to scape the semicolon so I need it.
- I split the execute immediate so now I have one execute immediate for every statement but I got an error in this statement:
EXECUTE IMMEDIATE 'COMMENT ON TABLE SYSADM.CVP_PAQ_SMS_REC_PRUEBA IS "COMMENT ON TABLE" '; The error I get is this:
ORA-01780: string literal required
Any suggestions about this ?
Thanks.

The comment itself needs to be a SQL string so it needs to be delimited with single quotes not double quotes. You can either use two single quotes
EXECUTE IMMEDIATE 'COMMENT ON TABLE SYSADM.CVP_PAQ_SMS_REC_PRUEBA IS ''COMMENT ON TABLE'' ';or you can use the q quoting syntax
EXECUTE IMMEDIATE q'[COMMENT ON TABLE SYSADM.CVP_PAQ_SMS_REC_PRUEBA IS 'COMMENT ON TABLE' ]';You cannot combine multiple DDL statements into a single block (well, you could use dynamic PL/SQL, but then your string would have a bunch of embedded EXECUTE IMMEDIATE statements which would presumably not buy you much).

Execute a DML query its length exceeds 4000 characters with execute immediate statement.

I want to execute a DML query with execute immediate statement. That DML query length exceeds 4000 characters. This query has Xquery related conditions, i can not split the query. when i tried execute it is giving "string literal too long".

How can I convert a Waveform to a String-Format?

Hello,
I write with "SQL-Execute.vi" datas to an Access-file. The "SQL-Execute.vi" needs a statement in String Format. And that is my problem. My source-datas (that I want to save to Access) are Waveforms. How can I convert the Waveform datas to a String Format?
Thanks for help!

Wire the waveform to the Get waveform componants function...from that you get t0, delta t and the sample values. Now you can generate whatever string you want based on that information...
You could e.g. wire the Y array to a for-loop in which you calculate the time of each sample by taking t0 and adding delta t multiplied with the array index, then you could convert the Y value and the time to strings using the seconds to time string and number to fractional string functions...etc etc...

Executing "if" conditions from a string

Hello,
I am making a webapp that reads if-statements from a local text file (MUMPS file actually). I will probably have those if statements parsed to a string, but is there any way to perhaps turn them into java code and execute them? I guess I can use string utils to make them look like java code (i.e. insert variable values), but how to I execute an 'if' condition that's in a string? The local file will change all the time, so hard-coding it is no option.
I can turn the if statements into something like this "if (1=3 && 5=2) || (!"smstring".equals("otstring"))"
Any help or direction would be appreciated.
Thanks!

Interesting. BeanShell looks neat. But aside from invoking an outside tool, there's no native way to do this. You'd have to parse it according to the rules of the grammar that the if statement conforms to, and then write java code to execute it.
Just please tell me you're not writing a MUMPS interpreter.

Page has more than 120 items (most of them are hidden), so my first thought is that page has problem with posting so many items, but APEX error message doesn't hel me at all. Any help would be very appreciated :)
Almir

Hi Almir,
actually it is the 100 page item limit. See (http://download.oracle.com/docs/cd/E17556_01/doc/user.40/e15517/limits.htm)
I also had a look into the source code and the code at the position where the error gets raised only supports 100 page items.
Can you have a look into the generated HTML code and look if you have a page items which is mapped to p_t101 or a higher number ?
I will file a bug to show a better error message.

How to execute commit statement in a procedure optionally?

We have a procedure which has DML operations and at the end there is a commit statement.
I want to execute commit statement optionally.
Like, when procedure runs directly it must execute commit statement, but when this procedure is called from a trigger don't run commit.
As you know commit operation is not allowed in triggers.
How can I understant the code is triggered from a trigger or any other (manuel exec or from another procedure).
I am looking for the reserved word that solve my problem. Like INSERTING, DELETING ....
Serkan
Thanks.

Hi oraserkan,
You do of course know it's dangerous to have a commit inside a procedure?
Consider this:
SQL> create table t (text varchar2(25))
Table created.
SQL> create or replace procedure p
as
begin
   insert into t(text)
       values ('Insert PROCEDURE');
   commit;
end p;
Procedure created.
SQL> insert into t(text)
    values ('Insert SQL')
1 row created.
SQL> exec p
PL/SQL procedure successfully completed.
SQL> rollback
Rollback complete.
SQL> select * from t
TEXT
Insert SQL
Insert PROCEDURE
2 rows selected.You should instead clearly state the procedure has a commit by making it autonomous, and then have two procedures, one that commits, and one that don't
SQL> drop procedure p
Procedure dropped.
SQL> drop table t purge
Table dropped.
SQL> create table t (text varchar2(25))
Table created.
SQL> create or replace procedure p_transactional
as
begin
   insert into t(text)
       values ('Insert PROCEDURE');
end p_transactional;
Procedure created.
SQL> create or replace procedure p_autonomous
as
   pragma autonomous_transaction;
begin
   p_transactional;
   commit;
end p_autonomous;
Procedure created.
SQL> insert into t(text)
    values ('Insert SQL')
1 row created.
SQL> exec p_autonomous
PL/SQL procedure successfully completed.
SQL> rollback
Rollback complete.
SQL> select * from t
TEXT
Insert PROCEDURE
1 row selected.
SQL> drop procedure p_transactional
Procedure dropped.
SQL> drop procedure p_autonomous
Procedure dropped.
SQL> drop table t purge
Table dropped.Regards

Executing SUBMIT statement in background

Hello Experts,
Is it possibe in executing SUBMIT statement in backgound? If yes can anyone provide example code?
Also in terms of performance tuning how does SUBMIT fares against CALL TRANSACTION? Which is much better in terms of performance.
Appreciate your answers. Thanks!

Hi
There's no difference for the performance:
if a transaction is assigned to a report (so no dialog program, module pool), it's better to use the SUBMIT if it needs to transfer the value on SELECTION-SCREEN. It can't do it by CALL TRANSACTION.
