select single will fetch only one record , in your terms it will fill only the header of internal table

select single matnr from mara into it_mara-matnr where matnr eq 'XXXXX'.

Hi,

When you do the select single, Header and the Body will filled up with a single record, the header record and the Body record will be same

Tables: mara. " here mara is only work area. You can take it as ONLY HEADER.

SELECT SINGLE *

FROM MARA

where matnr in s_matnr.

data:

t_mara like table of mara with header line.

SELECT SINGLE *

FROM MARA

into t_mara

where matnr in s_matnr.

In both the cases only the result will be populated into HEADER.

Not the table BODY.

So finally we have to use work area to get the select single output.

In general we will use this in VALIDATION cases. I mean to check the data is there in table for the specified ranges of values.

Hi,

SELECT SINGLE:

1. Select single is based on PRIMARY KEY

2. It will take the first record directly without searching of all relevant records.(Though you have lot of records for given condition)

Hi Ravi,

Select single is used for fetching only one value.

If any single value found .sy-subrc becomes zero.

<b>with out header.</b>

Select single matnr into w_area from mara where matnr in s_matnr.

append w_area to itab.

with header.

Select single matnr into table itab from mara where matnr in s_matnr.

Hi Ravi,

As it selects only one record at a time its not possible to directly insert into internal table's body. First select record into work area(headerline) then append it to internal table

DATA wa TYPE spfli.

SELECT SINGLE carrid connid cityfrom cityto

INTO CORRESPONDING FIELDS OF wa

FROM spfli

WHERE carrid EQ 'LH' AND connid EQ '0400'.

Hai,

SELECT SINGLE is a construct designed to read database records with primary key. In the absence of the primary key, it might end up doing a sequential search, whereas the select up to 1 rows may assume that there is no primary key supplied and will try to find most suitable index.

The best way to find out is through sql trace or runtime analysis.

The 'SELECT SINGLE' statement selects the first row in the database that it finds that fulfils the 'WHERE' clause If this results in multiple records then only the first one will be returned and therefore may not be unique.

Hi,

SELECT Single for only feching the data base tables then u can transfer to internal table. then u have to use

READ table tablename with key Primary key where value = internable value

in ur case only it will header value.

hi Ravi,

Select single is the syntax you use when you want to select a single record from the database . you can use it to populat the internal table with header and body or without header line .

here you go with a sample prog ...

REPORT ZTEST03.

tables: mara.

data: begin of itab occurs 0,

matnr like mara-matnr ,

end of itab.

select single * from mara

into CORRESPONDING FIELDS OF itab .

write: itab-matnr.

hope this helps !
