Dynamic SQl Query Select

[Former Member]

Hello Colleague,

I have a table that contains multiple entries of TABLE NAME.

I need to query the databse table and check if certain entry exist in that table.

I Loop over the table containing the tablenames and try a select :

Loop at lt_key into ls_key.

SELECT * FROM (ls_key) WHERE field = 'ABC' .

ENDLOOP.

It gives me a error and asks to store the result using INTO. Now i am confused with the type of result because the tablename is provided dynamically.

Could you please help.

Thanks in advance.

Hi,

Pass the name of the Table to the Field symbol.

ASSIGN (ls_key) TO <fs_tab>.

and then use this FS to get the data in SELECT statement

HI,

I did something similar to it, the following program accepts table

name and fields from user and sort dynamically.

REPORT  zreport_SORT.

parameters:
  p_f1(15) obligatory,
  p_f2(15) obligatory,
  p_f3(15) obligatory,
  p_table(15).

data:
  w_tab type ref to data,
  fs_tab type ref to data,
  w_flag,
  w_count type i.


create data w_tab type table of  (p_table) .
create data fs_tab type (p_table).

data:
  t_tab type table of spfli,
  fs_tab1 like line of t_tab.

field-symbols:
  <fs> type any table,
  <fs1> type any,
  <fs2> type any,
  <fs3> type any,
  <fs4> type any.

at selection-screen.

select count(*)
  from dd03l
  into w_count
 where tabname eq p_table
   and fieldname eq p_f1.
if w_count eq 0.
  w_flag = 'Y'.
 endif.
select count(*)
  from dd03l
  into w_count
 where tabname eq p_table
   and fieldname eq p_f2.

if w_count eq 0.
  w_flag = 'Y'.
 endif.

select count(*)
  from dd03l
  into w_count
 where tabname eq p_table
   and fieldname eq p_f3.

if w_count eq 0.
  w_flag = 'Y'.
 endif.
if w_flag eq 'Y'.
 clear w_flag.
 Message 'Incorrect field name' type 'E'.
endif.

start-of-selection.
assign w_tab->* to <fs>.
assign fs_tab->* to <fs1>.

  select *
    from (p_table)
    into corresponding fields of
   table <fs> up to 10 rows.
   sort <fs> by (p_f1) ascending (p_f2) ascending (p_f3) ascending.

assign component p_f1 of structure <fs1> to <fs2>.
assign component p_f2 of structure <fs1> to <fs3>.
assign component p_f3 of structure <fs1> to <fs4>.


  loop at <fs> into <fs1>.
  write:/ <fs2>,
          <fs3>,
          <fs4>.
  endloop.

Regards and Best wishes.

Why do you need this SELECT stmt ? Do you want to use the data selected from the table or just want to check if there are any entries in the table with field = 'ABC' ?

If you want to use the data:

DATA:
DREF TYPE REF TO DATA.

FIELD-SYMBOLS:
<ITAB> TYPE STANDARD TABLE.


LOOP AT ITAB INTO LS_KEY.

CREATE DATA DREF TYPE STANDARD TABLE OF (ls_key).
ASSIGN DREF->* TO <ITAB>.

SELECT * FROM (ls_key) WHERE field = 'ABC' INTO TABLE <ITAB>.

ENDLOOP.
