Hi all ,

how to Do this simple select in one time

i had this select and i want to know if there is a way to do it in one time without if and else since it similar

if hash_de is not initial .


SELECT SINGLE consumer_O
    FROM Z_dab
    INTO rv_consomer
    WHERE userid = iv_userid
    AND hash_de = mv_hash_deviceid.

else.

SELECT SINGLE consumer_O
    FROM Z_dab
    INTO rv_consomer
    WHERE userid = iv_userid.

endif.

i know that this i can do it in dynamic way with brackets but i don't want it .

there is other way to do it except dynamic ?

Regards

Chris

Hi,

If you dont want to do it dynamically with brackets, and want to make use of a single select, check this,

You will have to use a internal table instead of a single variable.



data: begin of itab occues 0,
         rv_consomer type string,
         hash_de type string,
         end of itab.

data: rv_consomer type string.

SELECT consumer_O hash_de
    FROM Z_dab
    INTO table itab
    WHERE userid = iv_userid.

if hash_de is not initial .
loop at itab where hash_de = mv_hash_deviceid.
rv_consomer = itab-rv_consomer.
exit.
endloop.
else. 
read table itab index 1.
rv_consomer = itab-rv_consomer.
endif.
write: rv_consomer

Hi Chris,

you can just put the hash_de into a range - BTW, souldn't it be

if mv_hash_deviceid. is not initial .

Then my proposal is:

data:
  lt_range_hash_de type range of Z_dab-hash_de.
field-symbols:
  <range_hash_de> like line of   lt_range_hash_de.
if mv_hash_deviceid is not initial.
  append initial line to  lt_range_hash_de  assigning  <range_hash_de> .
    <range_hash_de>  = 'IEQ'. "Set SIGN = 'I', OPTION = 'EQ'
    <range_hash_de>-low = mv_hash_deviceid .
endif.
 
 
SELECT SINGLE consumer_O
    FROM Z_dab
    INTO rv_consomer
    WHERE userid = iv_userid
    AND hash_de IN lt_range_hash_de.

If there is no mv_hash_deviceid , the range stays empty. Empty ranghes are ignored in WHERE condition.
