Select Single Statement

[Former Member]

Hi All,

ranges : r_docnum for edidc-docnum.

constants: c_ready_status(2) type c value '64'.

I have a following select single statement in my code..

the range r_docnum has more than 1000 records. This select is to check whether any IDoc is in ready status..

select single * from edidc

where docnum in r_docnum

and status eq c_ready_status.

This statement is giving a short dump.. pls let me know any way of avoiding the short dump.

Thank you,

Suresh

use this code

it will work

RANGES : r_docnum FOR edidc-docnum.

CONSTANTS: c_ready_status(2) TYPE c VALUE '64'.

SELECT * FROM edidc

WHERE docnum IN r_docnum

AND status EQ c_ready_status.

EXIT.

ENDSELECT.

is there any way you can reduce the size of r_docnum? For example are the numbers consecutive? If so, you could just take the high and low values and that will make your generated sql smaller.

eg

select single * from edidc

where docnum between low_docnum and high_docnum

and status eq c_ready_status.

Or if the numbers aren't actually consecutive but contain several groups of consecutive numbers you could put your own logic in to reduce the number of entries in r_docnum by replacing each group of entries with consecutive numbers with a 'BT' entry with the appropriate low and high values.

eg,

sort r_docnum.

CLEAR r_docnum2.

LOOP AT r_docnum.

IF NOT r_docnum2-low IS INITIAL.

currdiff = r_docnum-low - prevnum.

IF currdiff = 1.

r_docnum2-high = r_docnum-low.

ELSE.

IF r_docnum2-high IS INITIAL.

r_docnum2-option = 'EQ'.

ELSE.

r_docnum2-option = 'BT'.

ENDIF.

APPEND r_docnum2.

CLEAR r_docnum2.

ENDIF.

ENDIF.

prevnum = r_docnum-low.

IF r_docnum2 IS INITIAL.

r_docnum2-low = r_docnum-low.

ENDIF.

AT last.

IF r_docnum2-high IS INITIAL.

r_docnum2-option = 'EQ'.

ELSE.

r_docnum2-option = 'BT'.

ENDIF.

APPEND r_docnum2.

ENDAT.

ENDLOOP.

r_docnum[] = r_docnum2[].

Or where are you getting the r_docnum values from? If they are coming from a database table maybe could could change your select to use a join rather han storing the values in your range?

Try using SELECT UPTO 1 ROWS.

select * from edidc upto 1 rows

where docnum in r_docnum

and status eq c_ready_status.

Hi,

if you have populated R_DOCNUM through some logic say--

Loop at itab.

r_docnum-sign = 'I'.

..

r_docnum-low = itab-docnum.

append r_docnum.

endloop.

then you can try to..

loop at itab.

select single * from edidc

where docnum eq itab-docnum

and status eq c_ready_status.

endloop.

although this is not advisable (too many selects happening) you can avoid short dump with this.

Hi Suresh,

Ranges doesn't work if you have too many entries in it and it gives a short dump.

instead of ranges try using a internal table with the following statement

select single * from edidc

for all entries in itab

where status eq c_ready_status.

itab contains all the edidc-docnum.

Hope this helps.

or you could break it up into bite-sized chunks,

ranges r_docnum2 for vbak-vbeln

data packsize like sy-dbcnt default 100.

data firstline like sy-dbcnt.

data lastline like sy-dbcnt.

firstline = 1.

lastline = packsize.

clear sy-dbcnt.

do while sy-dbcnt = 0.

refresh r_docnum2.

loop at r_docnum from firstline to lastline.

append r_docnum to r_docnum2.

endloop.

select single * from edidc

where docnum in r_docnum2

and status eq c_ready_status.

firstline = firstline + packsize.

lastline = lastline + packsize.

enddo.

I think the dump he is getting is SQL statement too large. This is because of too many entries in r_docnum. What you need to do is to remove the r_docnum from the where clause and put it after it as follows.

DATA: BEGIN OF itab occurs 0.
        INCLUDE STRUCTURE edidc.
DATA: END OF itab.

SELECT * FROM edidc INTO TABLE itab
        WHERE status = c_ready_status.
DELETE itab WHERE NOT docnum IN r_docnum.
READ TABLE itab INDEX 1.
IF sy-subrc = 0.
*-- at least one document is in ready status
ELSE.
ENDIF.

removing r_docnum from the sql will certainly solve the dump problem........ but execution time could become an issue.

I think reducing the size of r_docnum or chunking it so that sql can deal with it is the better approach.
