Reading any value from table into a string (Especially date etc..)

[Former Member]

How would I read any value from a table into a string?

Currently doing the following...

data ret_val type string.

select single (wa_map-qes_field) from z_qekko into ret_val

where

angnr = _angnr.

When the source field is a date it bombs though.

The result goes into a BDCDATA-fval.

Not logged into a system at the moment, so can't check precisely, but you could do...

PARAMETERS: p_field TYPE fieldname.

DATA: lp_data TYPE REF TO DATA.
FIELD-SYMBOLS: <value>.

CREATE DATA lp_data LIKE (p_field).
ASSIGN lp_data->* TO <value>.

SELECT SINGLE (fieldname) FROM table INTO <value> WHERE...

select single

field1 from table

into v_field

where field1 = p_field.

May be I dont understand your solution but, that is even less generic.

Did you notice that the field is determined via select single (field_to_read) from into generic_type_of some sort

what data type did you use for v_field ?

Wouldnt the solution require some type of <fs>?

That looks good.

Will try it out now.

Thanks

Tried...

1 DATA: lp_data TYPE REF TO DATA.

2 FIELD-SYMBOLS: <value> TYPE ANY.

3 CREATE DATA lp_data LIKE (wa_map-qes_field).

4 ASSIGN lp_data->* TO <value>.

5 SELECT SINGLE (wa_map-qes_field) FROM zquadrem_qekko INTO <value> WHERE angnr = _angnr.

Complains that (wa_map-qes_field) is not defined in line 3.

Think that the bracket thing is only available via SQL.

What about CREATE DATA lp_data type ref to object. ?

Would the above declaration work?

REF TO OBJECT won't work.

Can you do CREATE DATA lp_data TYPE (wa_map-qes_field). ? Sorry - I like to check things before posting, but as I said, I've not got a system to log into today!

You can probably use RTTS - if your SAP version is high enough - to determine the correct type. Search on RTTS - there's some good documentation in SDN on it, with worked examples.

Hi,

I changed it to TYPE anyway and it worked.

Thanks, for your help!

tables:mara.

data:v_matnr like mara-matnr.

select-options: s_matnr for mara-matnr.

select single matnr

from mara

into v_matnr

where matnr in s_matnr.

write:/ v_matnr.
