Hey guys how to fetch data from db table using subroutine
hi guys,
I am fetching data from db table "mcha". now in the follwing code i get it in "HSDAT1_DATE."
now when i read out_tab with key "HSDAT1". it wont come in out_tab-value.plz tell me what is wrong whether some key condition in out_tab or any thing else.
and what should i write in changing && in script.
thanks in advance
FORM DATE_MGF TABLES IN_TAB STRUCTURE ITCSY
OUT_TAB STRUCTURE ITCSY.
tables :MCHA ,QALS.
DATA : WERKS1 LIKE QALS-WERK.
DATA : HSDAT1 LIKE MCHA-HSDAT.
DATA : DATE(2),
MONTH(2),
YEAR(4).
DATA : HSDAT1_DATE(10).
READ TABLE IN_TAB WITH KEY 'QALS-WERK'.
LOOP AT IN_TAB.
IF SY-TABIX EQ 1.
WERKS1 = IN_TAB-VALUE.
IF WERKS1 NE SPACE.
EXIT.
ENDIF.
ENDIF.
ENDLOOP.
SELECT SINGLE HSDAT INTO HSDAT1
FROM MCHA
WHERE WERKS = WERKS1.
DATE = HSDAT1+6(2).
MONTH = HSDAT1+4(2).
YEAR = HSDAT1+0(4).
CONCATENATE DATE '.' MONTH '.' YEAR INTO HSDAT1_DATE.
READ TABLE OUT_TAB WITH KEY 'HSDAT1' .
IF SY-SUBRC = 0.
OUT_TAB-VALUE = HSDAT1.
MODIFY OUT_TAB INDEX SY-TABIX.
ENDIF.
Hi,
Let me understanf clearly what you want.
initally mine out_tab is blank
According to you, your table out_tab is blank. And you need to add out_tab-value = HSDAT1_date.
READ TABLE OUT_TAB WITH KEY 'HSDAT1' .
IF SY-SUBRC = 0.
OUT_TAB-VALUE = HSDAT1.
MODIFY OUT_TAB INDEX SY-TABIX.
ENDIF.
So, if your table is blank, then read statement will fail.
Please let me know if your table out_tab in blank when you are reading the table and if this table contains any field called HSDAT.
Basically i would like to know your internal table out_tab declaration.
Thanks,
Archana

How to select data from a table using a date field in the where condition?
How to select data from a table using a date field in the where condition?
For eg:
data itab like equk occurs 0 with header line.
select * from equk into table itab where werks = 'C001'
and bdatu = '31129999'.
thanks.Hi Ramesh,
Specify the date format as YYYYMMDD in where condition.
Dates are internally stored in SAP as YYYYMMDD only.
Change your date format in WHERE condition as follows.
data itab like equk occurs 0 with header line.
select * from equk into table itab where werks = 'C001'
and bdatu = <b>'99991231'.</b>
I doubt check your data base table EQUK on this date for the existince of data.
Otherwise, just change the conidition on BDATU like below to see all entries prior to this date.
data itab like equk occurs 0 with header line.
select * from equk into table itab where werks = 'C001'
and <b> bdatu <= '99991231'.</b>

How to fetch data from 2 tables
Hi Experts,
I am using 2 Ztables.Let us assume that there are 2 fields in Table1 as a and b and 2nd Table contain c as field.I want to retrive data from these tables by combining the fields of Table1 with that of 2.
Eg: I want to compare a+b with c and fetch records.
Is there any logic to combine 2 fields and compare with 3rd field using a single select statement?
Regds,
Sam.Hi Sam,
if the tables have one or more common key fields, you can use a JOIN condition for the tables, i.e.
data:
begin of ls_target,
a like ztable1-a,
b like ztable1-b,
c like ztable2-c,
end of ls_target,
lt_target like table of ls_target.
select ztable1~a ztable1~b ztable2~c
into corresponding fields of table lt_target
from ztable1
join ztable2 ON ztable2~key = ztable1~key
where <your condition>.
Note ahead:
1) some people say select into corresponding fields is not good for performance. I think it is good to avoid errors and nobody ever gave a perfomance proof.
2) Most developers always use an alias such as ztable1AS a, ztable2 AS b. This is due to the fact that after table joins were introduced with release 3.1, the ABAP sample programs an documentation always used the ALIAS clause although it is not necessary nor does it establish transparency.
Kind regards

FETCHING DATA FROM A TABLE USING ARRAYLIST

This is the way to fetch data into 2d array , you can customize to fetch in array list .

You need to loop through the select option and concatenate with required data then select using 'in' instead of equal or select one by one.
or
select sales order numbers from VBAK for the selection into internal table then loop through the internal table and concatenate then select from CDHDR.
for better performance use objectclass in where clause. the value for sales order for objectclass is VERKBELEG.
in my system the object id is just an order number there is no other additions to it but in CDPOS the tabkey contains the order number with client and other information also.
the 30 may be your item number... check it
go ahead and change sales order and see what you can find in CDHDR
Good luck

How to fetch data from a table?
I am newbie and I have no idea how to do this. I have a table
(Excel File) about 1000 rows and 3 columns.
I want to load this table to the Flash and then be able to
fetch data by referring to the first column.
I am grateful for a tip to how to this simply. Thanx.Flash does not read Excel tables on local dirve. Flash can
read an XML or LoadVars file from local drive.
So if you can get the data exported into a text file using
either XML or LoadVars data structures, Flash has built-in classes
in its library to consume the data.
You can on a more advanced level use DCOM on a Windows IIS
server plus something like OLEDB to open an Excel table or any app
but it is not real practical for a production app involving more
than one user at a time. -
