Executing a Arithmatic formula stored in Variable

Hi all,
I need solution to execute a arithmatic operation which is stored in a variable.
For Example:
data : var type string.
var = ABS('-3').
Now by means of the variable var i need to get the absolute value of -3
ie my output should be 3 if i print the variable "var".
Please help.
Regards,
Vijayakumar

Hello,
Do like this.
REPORT ZV_SDN_3 .
DATA: STR TYPE STRING.
DATA: STR1 LIKE STR,
      INT TYPE I,
      LEN TYPE I.
STR = ABS('-3')..
LEN = STRLEN( STR ).
DO LEN TIMES.
IF NOT STR+INT(1) IS INITIAL.
    IF STR+INT(1) CA '0123456789'.
      CONCATENATE STR1 STR+INT(1) INTO STR1.
    ENDIF.
ENDIF.
ADD 1 TO INT.
ENDDO.
WRITE: STR1.
Hope this will solve ur issue.
Cheers,

Executing an Arithmatic Formula stored as String

Hi All,
Please help,
I have similar problem with Mr. Vijayakumar V.
I need to get result value of an arithmatic formula which stored as string.
ex:
zform = '( A / 2 ) + ( B * 1.25 + 2 )'.
if I have A = 10, and B = 4.
I do expect the final result to be : 12
for ( 5 + 7 ) = 12
Is there any simple way to do this or
Is there built in function in ABAP to deal with something like this?
Thank you,

Hi Oki,
You can solve your problem by generating subroutine at runtime.
Please look at sample code below:
REPORT z_jr05.
DATA: code(72) OCCURS 10,
 prog(8),
 msg(120),
 lin(3),
 wrd(10),
 off(3),
 var_string(50),
 p_result TYPE i.
var_string = 'temp_result = ( A * B ) + 199.'.
REPLACE ALL OCCURRENCES OF'A' IN var_string WITH '10'.
REPLACE ALL OCCURRENCES OF'B' IN var_string WITH '11'.
APPEND 'PROGRAM SUBPOOL.' TO code.
APPEND 'FORM HITUNG changing p_result.' TO code.
APPEND 'data: temp_result type i.' TO code.
APPEND var_string TO code.
APPEND 'p_result = temp_result.' TO code.
APPEND 'ENDFORM.' TO code.
GENERATE SUBROUTINE POOL code NAME prog
 MESSAGE msg LINE lin
 WORD wrd OFFSET off.
IF sy-subrc <> 0.
WRITE: / 'Error during generation in line', lin,
/ msg,
/ 'Word:', wrd, 'at offset', off.
ELSE.
WRITE: / 'The name of the subroutine pool is', prog.
SKIP 2.
PERFORM hitung IN PROGRAM (prog) CHANGING p_result.
WRITE p_result.
ENDIF.

How to execute a select query stored in variable

Hello helpers ,
I have some "select queries" stored in the database . Now I can derive this query in some variable . How do I execute this query from the variable .
example :
Data Query type char50 .
QueryVar = 'Select MATNR from MBEW where BWKEY = '0001' . '
How do I execute this Query stoored in variable QueryVar in ABAP program ?
Thanks a lot for helping .
Regards
Shashank

Shashank,
It is also possible to use (column_syntax) and (dbtab_syntax) together with (cond_syntax) when using SELECT statements in ABAP. For more info on (column_syntax) and (dbtab_syntax) just have a quick look at ABAP Keyword documention on SELECT statement (hit F1 on SELECT then scroll down to Select->Select result->Select Columns....)
So in your case, you need to separate out (split) the value in 'wa_itab-query' into other variables or append into separate internal tables using common keys etc. - then looping at those tables with the common key (READ TABLE WITH KEY....) use the following syntax at the time of triggering the SELECT query:
SELECT (column_syntax)
       FROM (dbtab_syntax)
       WHERE (cond_syntax).
Also worth a look at this example below:
PARAMETERS: p_cityfr TYPE spfli-cityfrom,
            p_cityto TYPE spfli-cityto.
DATA: BEGIN OF wa,
         fldate TYPE sflight-fldate,
         carrname TYPE scarr-carrname,
         connid   TYPE spfli-connid,
       END OF wa.
DATA itab LIKE SORTED TABLE OF wa
               WITH UNIQUE KEY fldate carrname connid.
DATA: column_syntax TYPE string,
      dbtab_syntax TYPE string.
column_syntax = `c~carrname p~connid f~fldate`.
dbtab_syntax = `( ( scarr AS c `
& ` INNER JOIN spfli AS p ON p~carrid = c~carrid`
& ` AND p~cityfrom = p_cityfr`
& ` AND p~cityto   = p_cityto )`
& ` INNER JOIN sflight AS f ON f~carrid = p~carrid `
& ` AND f~connid = p~connid )`.
SELECT (column_syntax)
       FROM (dbtab_syntax)
       INTO CORRESPONDING FIELDS OF TABLE itab.
LOOP AT itab INTO wa.
WRITE: / wa-fldate, wa-carrname, wa-connid.
ENDLOOP.
Hope this helps.
Cheers,
Sougata.

Storing a conditional formatting formula in a variable

I have a conditional formatting formula that exceeds the 393 character limit for Word fields. I've placed the formula directly into the template table, and it works correctly. But now, of course, there are several hundred characters of formatting information in that cell, along with the data field. Not pretty.
Is there a way to store that long formula into a variable, and then refer to that variable as the conditional format? I'm getting stuck on the right-arrow tags (>). I can't figure out how to include those in the string and store them in the variable.
Here's a simplified example of what I'm trying to do:
<?xdoxslt:set_variable($_XDOCTX,'myvar',"<?if:number(Sales) gt 1000000?><?attribute@incontext:color;'red'?><?end if?>")?>
The inclusion of the right-arrow tags (>) in the string causes a failure when attempting to Preview. If I replace all of the right-arrow tags with something else, like the number 8 ...
<?xdoxslt:set_variable($_XDOCTX,'myvar',"<?if:number(Sales) gt 1000000?8<?attribute@incontext:color;'red'?8<?end if?8")?>
... the string is stored in the variable, and I can refer to it in the template table by using <?xdoxslt:get_variable($_XDOCTX,'myvar')?>. It's useless, of course, but it works correctly. The string is stored in the variable, and the contents of the variable appear in the template.
So how can I imbed the right-arrow tags in this text string? Use an escape character? Imbed the ASCII code? I'd do either of those in a heartbeat if I could figure out the right syntax.

What is the best way to execute immediate particular sql stored in a table

I have a string variable containing row_ids eg "12,24,35,23"
and a table
row_id, sql
1 , "insert into some_table values(23,'Happy');"
6 , "insert into some_other_table values(24,'Sad');"
12 , "insert into some_table values(23,'Crazzzy');"
15 , "insert into some_other_table values(23,'Old');"
23 , "insert into another_table values(23,'Left');"
24 , "insert into stuff_table values(23,'Gold');"
30 , "insert into old_table values(23,'Even');"
35 , "insert into archive_table values(23,"True");"
And I need to write a plsql function that takes the list of row_ids as an argument and executes the sql statements stored in the table that matches.
I am trying a combination of cursor and execute immediate statements to do it at the moment but suspect I am being very inefficient. So any suggestions or examples of similar code anyone knows about would be hugely appreciated.
Cheers
Reuben

Not sure why anyone would be doing such a thing as storing their SQL in a table and wanting to dynamically execute it (generally this is bad practice), but if you must...

 23 insert into another_table values(23,'Left');
 24 insert into stuff_table values(23,'Gold');

How to execute a string formula and assign the result to a number field

How to execute a string formula and assign the result to a number field
Hi,
we have a function that returns a string like this:
'(45+22)*78/23'
After we should calculate this string and assign the value to a numeric block field
Example:
k number(16,3);
k:=fun1('(45+22)*78/23'); where fun1 execute and translate to number the string.
Does exist a function like fun1 ??
How can we do ?

How to get values from a stored package variable of type record ?

Sir,
In my JClient form, I need to get values from a database stored package variable of type record. And the values are retained in the JClient form for the whole session. The values are copied only once when the form is started.
What is the best way to do that ?
Thanks
Stephen

Stephen,
not sure what your model is, but if it is Business Components, I think I would expose the properties as a client method on the application module. This way all JClient panels and frames will have access to it. You could use a HashMap to store the data in teh app module.
If JDBC supports the record type, then you should be able to call it via a prepared SQL statement. If not, you may consider writing a PLSQL accessor to your stored procedure that returns something that can be handled.

How to interpret a formula stored in a transparent table

Dear all,
I have filled in a specific transparent table with some formula. I would like to read the table, find the formula and take the result of this formula in a variable
In my table :
Country, formula 1, formula 2
FR, P + 1 ( 1 / 80 ), R * 1 ( 1 - 30 )
In my program,
I read the table with the country as key, and I would like, first to replace the P and R by a value in the program, and I would like to interpret the formula and put the result of this in a variable
if Country = FR
replace P by w_price in formula1
replace R by w_tva in formula2
w_result1 = formula1
w_result2 = formula2
I don't know how to do interpret these 2 statement like :
w_result1 = w_price + 11 ( 1 / 80 )
w_result2 = w_tva * 1 ( 1 - 30 )
I tought to use the field symbol and assign but w/o success for the moment
Can anybody help me ? it is very important.
Thanks
Kind regards
Véronique

Hello,
I think my questions was not so clear.
In fact, the formula is in a field in a transparent table
for example : my_table has a field my_formula. In this field I have written: P + 1 ( 1 / 80 )
I need to interpret the content of the field my_formula to solve the formula and put the result in a variable.
I don't want to write the formula directly in the program
thanks

Error when executing statement for table/stored proc

Hi All,
 I am getting this error when executing IDOC to JDBC (Stored Procedure) Scenario.
 In my stored procedure I have three insert statements to insert rows in to 3 tables.
 This stored procedure is working fine for two insert statements i.e,
 For this I have created data type for stored procedure with 10 elements and executed the scenario and was successfully running.
 when I added 3rd insert statement to stored procedure ie., when i added 5 more elements to the datatype (totally 15 elements) it starts giving the bellow error in Message Monitoring.
Exception caught by adapter framework: Error processing request in sax parser: Error when executing statement for table/stored proc. 'COGRP_TMP_PROC_1' (structure 'Statements'): java.sql.SQLException: General error

'COGRP_TMP_PROC_1' (structure 'Statements'): java.sql.SQLException: General error
 Note:- I have run the stored procedure with three insert statements in Sql Server, and also by calling an external program also, and was working fine.
 Note : Is there any structure needs to be follow when working with IDOC to Stored procedure.
I am struck up with the error, can any body resolve this issue.
Thanks in Advance,

Hi narasimha,
 This seems to be any error due to incorrect query formation.In your receiver jdbc channel set the parameter logSQLstatement = true.you can find this parameter in the advanced mode. Using this parameter you will be able to see the sql query which is generated at runtime in the audit log in RWB.

How to execute .sql file in Stored Procedure?

Hi,
I have an urgent requirement, where i have to execute .sql file form Stored Procedure.
This .sql file will have set of update statement. I need to pass value to this update statement.
Kindly please help me.
Regards,
Irfan

This is required as part of Data Migration where i have to do 100 of table's update. Each time update table will defer, so its better to have in separate script file (.sql). Can u paste some sample/syntax to exceute .sql file from stored procedure. I am new to this PL/SQL.
How have you determined that it's "better" to have seperate scripts? I assume you mean the table name will "differ" (and not "defer" - I assume that's just because English isn't your first language? no problem - I think I understand what you're asking).
So what I think you're asking is that you have dynamic table names but each table needs to be updated in the same way?
Question: Why do you have tables with different names that all need the same process doing to them?
Assuming it's a valid requirement (and 99% of the time doing dynamic coding implies it's not).... you could use dynamic code, rather than 'scripts'...
e.g.
create procedure update_table(tbl_name varchar2) is
begin
execute immediate 'update '||tbl_name||' set lastupdate = null';
end;
As you haven't bothered to provide a database version, any example code/data or explanation of what you're actually doing, you're not going to get any detailed answer. Please do take the time to read the FAQ and post appropriate details so people can help you.
