Dynamic read statement

Hi Everyone,
Here is my problem..
I am dynamically creating an internal table based on select-option table entered by user.
The key for this table can be determined only at runtime.
The table entered might have by one field as key field or 10 key fields..
How can I use the dynamic read in this situation

Hi,
This is the form of read statement upto 10 keyfields,
You can read some std tables/FM to get the key fields of a table.
Later you can assign the key fields field symbols as shown:-
* Loop to assign fieldnames & values to READ TABLE keyfields
         LOOP AT li_keyfields INTO work_area WHERE keyfield EQ 'X' .
           l_index = l_index + 1.
           CASE l_index.
             WHEN 1.
               ASSIGN COMPONENT work_area-fieldname OF STRUCTURE work_area TO <fs_c1>.
               MOVE work_area-fieldname TO l_key1.
             WHEN 2.
               ASSIGN COMPONENT work_area-fieldname OF STRUCTURE work_area TO <fs_c2>.
               MOVE work_area-fieldname TO l_key2.
             WHEN 3.
               ASSIGN COMPONENT work_area-field OF STRUCTURE work_area TO <fs_c3>.
               MOVE work_area-fieldname TO l_key3.
             WHEN 10.
               ASSIGN COMPONENT work_area-fieldname OF STRUCTURE work_area TO <fs_c10>.
               MOVE work_area-fieldname TO l_key10.
           ENDCASE.
         ENDLOOP.
READ TABLE <fs_itab> ASSIGNING <fs_wa>
             WITH KEY (l_key1) = <fs_c1>
                      (l_key2) = <fs_c2>
                      (l_key10) = <fs_c10>.

Dynamic internal table and dynamic read statements.

Hi,
My Scenario :
I have two dynamic internal tables.
I am looping at one internal table and trying to read another table.
In the read statement how do I mention the key dyamically.
Example code below :
LOOP AT <dyn_table> ASSIGNING <dyn_wa>.
read second dynamic internal table.
enloop.
The key which I want use for reading say it is keyed in the selection criteria....
Also based on the value I read I want to modify the first internal table field value.
Remember I dont want to explicity mention the key
How do I do that?
Thanks
Krishna.

Hi
U need to use the field-symbol, but u can't use a WHERE option, but u need to use the CHECK statament into the second loop:
LOOP AT <dyn_table> ASSIGNING <dyn_wa>.
    LOOP AT <DYN_TABLE2> ASSIGNING <DYN_WA2>.
        ASSIGN COMPONENT <COMPONENT> OF STRUCTURE   <DYN_WA2> TO <FS>.
        CHECK <FS> IN (=) .......
            ASSIGN COMPONENT <COMPONENT> OF STRUCTURE   <DYN_WA> TO <FS2>.
            <FS2> = .......
            EXIT.
    ENDLOOP.

Need help regarding Dynamic Read Table statement

Hello
I know that the syntax for dymanic read table statement is
READ TABLE <ITAB> WITH KEY (KEY1) = VALUE1 (KEY2) = VALUE2 .....(KEYN) = VALUEN
Here is my problem..
I am dynamically creating an internal table based on parameter table entered by user.
The key for this table can be determined only at runtime.
The table entered might have by one field as key field or 10 key fields..
How can I use the dynamic read in this situation ?
Thanks for your help in advance,

Hello Santosh,
please check out the following solution. The program demonstrates how to use the dynamic read statement with three key field conditions. Additional key fields can be added in the same way.
REPORT z_dynamic_read.
DATA: gt_itab TYPE REF TO data,
      ge_key_field1 TYPE char30,
      ge_key_field2 TYPE char30,
      ge_key_field3 TYPE char30,
      go_descr_ref TYPE REF TO cl_abap_tabledescr.
FIELD-SYMBOLS: <gt_itab> TYPE STANDARD TABLE,
               <gs_key_comp> TYPE abap_keydescr,
               <gs_result> TYPE ANY.
PARAMETERS: pa_table TYPE tabname16 DEFAULT 'SPFLI',
            pa_cond1 TYPE string DEFAULT sy-mandt,
            pa_cond2 TYPE string DEFAULT 'LH',
            pa_cond3 TYPE string DEFAULT '0123'.
START-OF-SELECTION.
* Create and populate internal table
CREATE DATA gt_itab TYPE STANDARD TABLE OF (pa_table).
ASSIGN gt_itab->* TO <gt_itab>.
SELECT * FROM (pa_table) INTO TABLE <gt_itab>.
* Get the key components into the fields ge_key_field1, ...
go_descr_ref ?= cl_abap_typedescr=>describe_by_data_ref( gt_itab ).
LOOP AT go_descr_ref->key ASSIGNING <gs_key_comp>.
    CASE sy-tabix.
      WHEN 1.
        ge_key_field1 = <gs_key_comp>-name.
      WHEN 2.
        ge_key_field2 = <gs_key_comp>-name.
      WHEN 3.
        ge_key_field3 = <gs_key_comp>-name.
    ENDCASE.
ENDLOOP.
* Finally, perform the search
READ TABLE <gt_itab> ASSIGNING <gs_result>
          WITH KEY (ge_key_field1) = pa_cond1
                   (ge_key_field2) = pa_cond2
                   (ge_key_field3) = pa_cond3.
IF sy-subrc = 0.
    WRITE / 'Record found.'.
ELSE.
    WRITE / 'No record found.'.
ENDIF.
One note: When an internal table is created dynamically like in my program above, the table key is not the key defined in the DDIC structure -- instead, the default key for the standard table is used (i.e. all non-numeric fields).
Hope this helps,
David

Read statement on dynamic internal tables

Hello All,
I have a dynamic internal table <G_T_ITAB> with fields F1, F2, F3 & F4 .
I want to read the internal table <G_T_ITAB>. So im using the below code.
LOOP AT G_T_DATA.
READ TABLE <G_T_ITAB> INTO <G_R_ITAB> WITH KEY F1 = G_T_DATA-F1.
IF SY-SUBRC <> 0.
ELSE.
ENDIF.
ENDLOOP.
But this is giving syntax error that F1 is not the field of <G_T_ITAB>. But the field is there in <G_T_ITAB>.
Can you suggest me to solve this issue. Or is there any other approach to use READ statement on dynamic internal tables.
Thanks in advance.
Best Regards,
Sasidhar Reddy Matli.

Dynamic IF statement in PL/SQL on-insert trigger in Forms 6.0

I would like to build a dynamic IF statement for the on-insert trigger in a form... Users are restricted to which "projects" they are allowed to enter into the database. These restrictions are based on a security table. The same restrictions are used to build the dynamic where clause that limits which previously inserted records the users can see when they are in the form. Since the restrictions are identical, I want to use the same logic that I use to build a where clause to build a dynamic If statement instead... If the statement is true, the user can insert the record. If its false, they can't.
I'm trying to this as follows:
declare
big_if varchar2(10000) :=' ';
begin
if :global.admin='YES'
then
insert_record;
else
declare
cursor cur1 is
select paren1, field, comparison_operator, value, paren2, and_or
from rcdb.user_project_assign2
where user_id = user;
c1_rec cur1%ROWTYPE;
begin
for c1_rec in cur1 loop
big_if:= big_if | | c1_rec.paren1 | | ':tbl_main_data.' | |c1_rec.field | |c1_rec.comparison_operator | | '''' | | c1_rec.value | | '''' | | c1_rec.paren2 | | ' '| | c1_rec.and_or | | ' ';
end loop;
end;
if big_if
then
insert_record;
else message('You are not allowed to insert this record');
end if;
end if;
end;
The problem is in the line
IF big_if
big_if is the variable that holds the text to my if statement (hense dynamic If statement) but I can't get the code to allow me to use that variable.
Can anyone do this?
null

That code was great, but forms isn't allowing me to use the dbms_sql so I have to make a procedure out of forms and call it from the form. Both my form code and the procedure are compiling, but I"m still getting an error when the result is coming back to the form...
the code in the form is:
declare
big_if varchar2(10000) :=' ';
result varchar2(5) :=' ';
check_state varchar2(2):=:tbl_main_data.state_abr;
check_region varchar2(3):=:tbl_main_data.region_abr;

message('resulte = | |result| |');
if result = 'TRUE' then insert_record;
else
message ('you cant enter');
end if;
end if;
end;
AND THE CODE IN THE PROCEDURE IS....
create or replace procedure check_if (

Hello,
how do you create your internal table "<FS_IT_CRV>" ?
i found this thread [here|Need help regarding Dynamic Read Table statement;.
You can try the code lines of David Klotz.
If you insert a sort statement before read and change read adding binary search it might work.
SORT <gt_itab> BY (ge_key_field1) (ge_key_field2) (ge_key_field3) .
* Finally, perform the search
READ TABLE <gt_itab> ASSIGNING <gs_result>
          WITH KEY (ge_key_field1) = pa_cond1
                   (ge_key_field2) = pa_cond2
                   (ge_key_field3) = pa_cond3 BINARY SEARCH.
I tried the following code in my own program and it works:
SORT <wlf_t_data> BY (c_trkorr).
read table <wlf_t_data> assigning <wlf_header> with key
         (c_trkorr) = 'DRR' binary search.
Where   <wlf_t_data> is a dynamic table created by method create_dynamic_table of class cl_alv_table_create.

Dynamic SELECT statement causing CX_SY_DYNAMIC_OSQL_SEMANTICS error.

Hello Gurus,
We have a dynamic SELECT statement in our BW Update Rules where the the Selection Fields are populated at run-time and so are the look-up target and also the WHERE clause. The code basically looks like below:
          SELECT (lt_select_flds)
            FROM (lf_tab_name)
            INTO CORRESPONDING FIELDS OF TABLE <lt_data_tab>
            FOR ALL ENTRIES IN <lt_source_data>
            WHERE (lf_where).
In this instance, we are selecting 5 fields from Customer Master Data and the WHERE condition for this instance of the run is as below:
WHERE: DIVISION = <lt_source_data>-DIVISION AND DISTR_CHAN = <lt_source_data>-DISTR_CHAN AND SALESORG = <lt_source_data>-SALESORG AND CUST_SALES = <lt_source_data>-SOLD_TO AND OBJVERS = 'A'
This code was working fine till yesterday when we encountered serious performance problems and the Basis team had to do some changes at the DB level [Oracle]. Ever since, when we execute our data load, we get the CX_SY_DYNAMIC_OSQL_SEMANTICS.
Is setting changes at the Oracle level cause issues with how the data is being read at the DB. If yes, can you suggest what can we do to this code to get is working correctly [in case Basis can't revert back their changes]?
Would appreciate any help we can get here.

You don't understand - this error comes up when we run specific BEx queries. It was working yesterday, but today it is not. Our support package did not change from yesterday. We did not apply any OSSnotes.
We are however doing pre-prepare on our Prod system.
The temporary table is used to store SIDs for use in the join. the table exists in the dictionary, but not at an Oracle level.

Read statement

what is the exact use of read statement. How it is used in int.table & database table.

Hi
Reading Lines of Tables
To read a single line of any table, use the statement:
READ TABLE <itab> <key> <result>.
For the statement to be valid for any kind of table, you must specify the entry using the key and not the index. You specify the key in the <key> part of the statement. The <result> part can specify a further processing option for the line that is retrieved. If the system finds an entry, it sets SY-SUBRC to zero, if not, it takes the value 4, as long as it is not influenced by one of the possible additions. If the internal table is an index table, SY-TABIX is set to the index of the line retrieved. If the table has a non-unique key and there are duplicate entries, the first entry is read. Specifying the Search Key The search key may be either the table key or another key.
Using the Table Key To use the table key of <itab> as a search key, enter <key> as follows:
READ TABLE <itab> FROM <wa> <result>.
or as follows
READ TABLE <itab> WITH TABLE KEY <k1> = <f1> ... <kn> = <fn> <result>.
In the first case, <wa> must be a work area compatible with the line type of <itab>. The values of the key fields are taken from the corresponding components of the work area. In the second case, you have to supply the values of each key field explicitly. If you do not know the name of one of the key fields until runtime, you can specify it as the content of a field <ni> using the form (<ni>) = <fi>. If the data types of <fi> are not compatible with the key fields, the system converts them. The system searches for the relevant lines as follows:
Standard tables
Linear search, where the runtime is in linear relation to the number of table entries.
Sorted tables
Binary search, where the runtime is in logarithmic relation to the number of table entries.
Hashed tables
The entry is found using the hash algorithm of the internal table. The runtime is
independent of the number of table entries.
Using a Different Search Key
To use a key other than the table key as a search key, enter <key> as follows:
READ TABLE <itab> WITH KEY = <f> <result>.
or as follows
READ TABLE <itab> WITH KEY <k1> = <f1> ... <kn> = <fn> <result>.
BC - ABAP Programming SAP AG
In the first case, the whole line of the internal table is used as the search key. The contents of the entire table line are compared with the contents of field <f>. If <f> is not compatible with the line type of the table, the value is converted into the line type. The search key allows you to find entries in internal tables that do not have a structured line type, that is, where the line is a single field or an internal table type. In the second case, the search key can consist of any of the table fields <k1>...<kn>. If you do not know the name of one of the components until runtime, you can specify it as the content of a field <ni> using the form (<ni>) = <fi>. If <ni> is empty when the statement is executed, the search field is ignored. If the data types of <fi> are not compatible with the components in the internal table, the system converts them. You can restrict the search to partial fields by pecifying offset and length.The search is linear for all table types. The runtime is in linear relation to the number of table lines. Specifying the Extra Processing Option
You can specify an option that specifies what the system does with the table entry that it finds. Using a Work Area You can write the table entry read from the table into a work area by specifying <result> as follows:
READ TABLE <itab> <key> INTO <wa> [COMPARING <f1> <f2> ...
|ALL FIELDS]
[TRANSPORTING <f1> <f2> ...
|ALL FIELDS
|NO FIELDS].
If you do not use the additions COMPARING or TRANSPORTING, the contents of the table line must be convertible into the data type of the work area <wa>. If you specify COMPARING or TRANSPORTING, the line type and work area must be compatible. You should always use a work area that is compatible with the line type of the relevant internal table. If you use the COMPARING addition, the specified table fields <fi> of the structured line type are compared with the corresponding fields of the work area before being transported. If you use
the ALL FIELDS option, the system compares all components. If the system finds an entry with the specified key <key> and if the contents of the compared fields are the same, SY-SUBRC is set to 0. If the contents of the compared fields are not the same, it returns the value 2. If the system cannot find an entry, SY-SUBRC is set to 4. If the system finds an entry, it copies it into the target work area regardless of the result of the comparison. If you use the TRANSPORTING addition, you can specify the table fields of the structured line type that you want to transport into the work area. If you specify ALL FIELDS without RANSPORTING, the contents of all of the fields are transported. If you specify NO FIELDS, no fields are transported. In the latter case, the READ statement only fills the system fields SYSUBRC and SY-TABIX. Specifying the work area <wa> with TRANSPORTING NO FIELDS is unnecessary, and should be omitted.
In both additions, you can specify a field <fi> dynamically as the contents of a field <ni> in the form (<ni>). If <ni> is empty when the statement is executed, it is ignored. You can restrict the search to partial fields by specifying offset and length.
Using a Field SymbolYou can assign the table entry read from the table to a field symbol by specifying <result> as
follows:
READ TABLE <itab> <key> ASSIGNING <FS>.
After the READ statement, the field symbol points to the table line. If the line type is structured, you should specify the same type for the field symbol when you declare it. This allows you to address the components of the field symbol. If you cannot specify the type statically, you must use further field symbols and the technique of assigning components of structures to address the components of the structure.For further information about assigning table lines to field symbols, refer to Access Using Field Symbols.
SORT ITAB.
READ TABLE ITAB WITH KEY VAR1 <= SYDATUM BINARY SEARCH.

DYnamic select statement in JDBC adapter?

Hi guys,
Is it possible so send dynamic select statement in jdbc adapter?
XIer

Aamir,
The poster did not specify whether this was sender or receiver channel, but it would only make sense that a "dynamic query" must be on the receiver communication channel since if it was on the sender channel, the channel would have to intelligently determine how to do dynamic queries.
Also, the poster asked if there was a way to "send a dynamic query" to the channel. This seems to imply that the channel is receiving information from somewhere to determine the query, which could only mean it is a receiver channel.
If you would like more information on the JDBC sender communication channel, please open a new thread.

Dynamic UPDATE statement with parameters for column names.

Getting result of dynamic select statement into variable

I have a function that builds a dynamic sql statement. I then want to take the result of that statement and insert it into a variable. I have tried this
execute immediate strSQL USING OUT intCounter;but that is giving me an error on that line of code. The SQL is a select count(*) and works fine. It is just how to get it into the variable that is tripping me up.

END VALIDATIONQUESTIONRESULT; strSQL when checked builds perfectly. I get 100% what I expect from it. An example of what I am getting from strSQL is:
select count(*) from Procedures where TO_CHAR(ProcdDt, 'MM') = TO_CHAR(ADD_MONTHS(SYSDATE, -1), 'MM') and TO_CHAR(ProcdDt, 'YYYY') = TO_CHAR(ADD_MONTHS(SYSDATE, -12), 'YYYY') and PPATID in (select PATID from DEMOGRAPHICS where PARTICID = 12);I am getting the number I would expect from this. I just need to put that number into intCounter. I tried altering strSQL so it looked like this:
select count(*) into intCounter from Procedures where TO_CHAR(ProcdDt, 'MM') = TO_CHAR(ADD_MONTHS(SYSDATE, -1), 'MM') and TO_CHAR(ProcdDt, 'YYYY') = TO_CHAR(ADD_MONTHS(SYSDATE, -12), 'YYYY') and PPATID in (select PATID from DEMOGRAPHICS where PARTICID = 12);but that gave me an error on the execute immediate line as well.
Sorry, I thought it would be simple so that was why I only put that bit of info. I guess it is more complicated than it at first appeared!

Preparing Dynamic SQL statement for inserting in Pro*C

Hi Friends,
From quite some time i am struggling writing Dynamic SQL statement for dynamic insert and update in Pro*C.
Can somebody go through my code and suggest me the rigth way of doing.
Right now it throws an error saying " Error while updating ORA-00904: invalid column name "
Please help me.
Girish.
int main()
EXEC SQL BEGIN DECLARE SECTION;
char *uid ="scott/tiger";
static char sqlstmt[129];
struct /* DEPT record */
int dept_num;
char dept_name[15];
char location[14];
} dept_rec;
EXEC SQL END DECLARE SECTION;
EXEC SQL WHENEVER SQLERROR DO sql_error();
EXEC SQL CONNECT :uid;
dept_rec.dept_num = 50;
strcpy(dept_rec.dept_name,"ADMIN");
strcpy(dept_rec.location,"IN");
strcpy(sqlstmt,"UPDATE dept set DNAME = dept_rec.dept_name where DEPTNO = dept_rec.dept_num");
EXEC SQL EXECUTE IMMEDIATE:sqlstmt;
EXEC SQL COMMIT;
exit(0);
void sql_error()
printf("\nError while updating %s",sqlca.sqlerrm.sqlerrmc);
EXEC SQL ROLLBACK;
}

A bit rusty here but this is how I see it.
Think of it this way ..
all Oracle is going to see is:
UPDATE dept set DNAME = dept_rec.dept_name where DEPTNO = dept_rec.dept_num
Its NOT going to know what dept_rec.dept_name is or dept_rec.dept_num is ..
it doesnt go back and fill in those values.
You need something like
strcpy(sqlstmt,"UPDATE dept set DNAME = \"");
strcat(sqlstmt,dept_rec.dept_name);
strcat(sqlstmt,"\" where DEPTNO = ");
strcat(sqlstmt,dept_rec.dept_num);
printf(sqlsmt); # Just to be sure the update statement look right during testing.

Creating a Dynamic Update Statement based on Select

hi,
i'm trying to create a dynamic update statement based on select statement
my requirment is to query a joint tables and get the results then based on the results i need to copy all the data and create an update statement for each row
for ex
the update statement should look like this
update iadvyy set SO_SWEEP_CNT = '1' where inst_no = '003' and memb_cust_no = 'aaaaaaaaaaaaaaaa';
and the select statement like the following
select substr(key_1,11,9) account_no,sord_mast SO_SWEEP_CNT from
select acct_no,count(*) sord_mast from
(select from_acct_no acct_no,update_mast
from sord where FROM_SYS in ('DEP','INV') and TERM_DATE > 40460
union all
select to_acct_no acct_no,update_mast
from sord where TO_SYS in ('DEP','INV') and TERM_DATE > 40460)
group by Acct_no)
right outer join
invm
on
key_1 = '003'||acct_no
where sord_mast > 0;
so taking the above two columns from the above select statement and substitue the values as separate update statement.
is that doable , please share your knowledge with me if poosible
thanks in advanced

is that doable , please share your knowledge with me if poosibleyes
The standard advice when (ab)using EXECUTE IMMEDIATE is to compose the SQL statement in a single VARCHAR2 variable
Then print the SQL before passing it to EXECUTE IMMEDIATE.
COPY the statement & PASTE into sqlplus to validate its correctness.

Regardin read statement

When i am using read statement to read the contents of a table using a key field
I am getting a warning in Code Inspector as "Sequential read access possible for a sorted table" Can anyone provide me a solution

hi ,
Reading Lines of Tables
To read a single line of any table, use the statement:
READ TABLE <itab> <key> <result>.
For the statement to be valid for any kind of table, you must specify the entry using the key and not the index. You specify the key in the <key> part of the statement. The <result> part can specify a further processing option for the line that is retrieved. If the system finds an entry, it sets SY-SUBRC to zero, if not, it takes the value 4, as long as it is not influenced by one of the possible additions. If the internal table is an index table, SY-TABIX is set to the index of the line retrieved. If the table has a non-unique key and there are duplicate entries, the first entry is read. Specifying the Search Key The search key may be either the table key or another key.
Using the Table Key To use the table key of <itab> as a search key, enter <key> as follows:
READ TABLE <itab> FROM <wa> <result>.
or as follows
READ TABLE <itab> WITH TABLE KEY <k1> = <f1> ... <kn> = <fn> <result>.
In the first case, <wa> must be a work area compatible with the line type of <itab>. The values of the key fields are taken from the corresponding components of the work area. In the second case, you have to supply the values of each key field explicitly. If you do not know the name of one of the key fields until runtime, you can specify it as the content of a field <ni> using the form (<ni>) = <fi>. If the data types of <fi> are not compatible with the key fields, the system converts them. The system searches for the relevant lines as follows:
Standard tables
Linear search, where the runtime is in linear relation to the number of table entries.
Sorted tables
Binary search, where the runtime is in logarithmic relation to the number of table entries.
Hashed tables
The entry is found using the hash algorithm of the internal table. The runtime is
independent of the number of table entries.
Using a Different Search Key
To use a key other than the table key as a search key, enter <key> as follows:
READ TABLE <itab> WITH KEY = <f> <result>.
or as follows
READ TABLE <itab> WITH KEY <k1> = <f1> ... <kn> = <fn> <result>.
BC - ABAP Programming SAP AG
In the first case, the whole line of the internal table is used as the search key. The contents of the entire table line are compared with the contents of field <f>. If <f> is not compatible with the line type of the table, the value is converted into the line type. The search key allows you to find entries in internal tables that do not have a structured line type, that is, where the line is a single field or an internal table type. In the second case, the search key can consist of any of the table fields <k1>...<kn>. If you do not know the name of one of the components until runtime, you can specify it as the content of a field <ni> using the form (<ni>) = <fi>. If <ni> is empty when the statement is executed, the search field is ignored. If the data types of <fi> are not compatible with the components in the internal table, the system converts them. You can restrict the search to partial fields by pecifying offset and length.The search is linear for all table types. The runtime is in linear relation to the number of table lines. Specifying the Extra Processing Option
You can specify an option that specifies what the system does with the table entry that it finds. Using a Work Area You can write the table entry read from the table into a work area by specifying <result> as follows:
READ TABLE <itab> <key> INTO <wa> [COMPARING <f1> <f2> ...
|ALL FIELDS]
[TRANSPORTING <f1> <f2> ...
|ALL FIELDS
|NO FIELDS].
If you do not use the additions COMPARING or TRANSPORTING, the contents of the table line must be convertible into the data type of the work area <wa>. If you specify COMPARING or TRANSPORTING, the line type and work area must be compatible. You should always use a work area that is compatible with the line type of the relevant internal table. If you use the COMPARING addition, the specified table fields <fi> of the structured line type are compared with the corresponding fields of the work area before being transported. If you use
the ALL FIELDS option, the system compares all components. If the system finds an entry with the specified key <key> and if the contents of the compared fields are the same, SY-SUBRC is set to 0. If the contents of the compared fields are not the same, it returns the value 2. If the system cannot find an entry, SY-SUBRC is set to 4. If the system finds an entry, it copies it into the target work area regardless of the result of the comparison. If you use the TRANSPORTING addition, you can specify the table fields of the structured line type that you want to transport into the work area. If you specify ALL FIELDS without RANSPORTING, the contents of all of the fields are transported. If you specify NO FIELDS, no fields are transported. In the latter case, the READ statement only fills the system fields SYSUBRC and SY-TABIX. Specifying the work area <wa> with TRANSPORTING NO FIELDS is unnecessary, and should be omitted.
In both additions, you can specify a field <fi> dynamically as the contents of a field <ni> in the form (<ni>). If <ni> is empty when the statement is executed, it is ignored. You can restrict the search to partial fields by specifying offset and length.
Using a Field SymbolYou can assign the table entry read from the table to a field symbol by specifying <result> as
follows:
READ TABLE <itab> <key> ASSIGNING <FS>.
After the READ statement, the field symbol points to the table line. If the line type is structured, you should specify the same type for the field symbol when you declare it. This allows you to address the components of the field symbol. If you cannot specify the type statically, you must use further field symbols and the technique of assigning components of structures to address the components of the structure.For further information about assigning table lines to field symbols, refer to Access Using Field Symbols.

Need to wite pl sql procedure for dynamic select statement

Need pl sql procedure for a Dynamic select statement which will drop tables older than 45 days
select 'Drop table'||' ' ||STG_TBL_NAME||'_DTL_STG;' from IG_SESSION_LOG where substr(DTTM_STAMP, 1, 9) < current_date - 45 and INTF_STATUS=0 order by DTTM_STAMP desc;

I used this to subtract any data older than 2 years, adjustments can be made so that it fits for forty five days, you can see how I changed it from the originaln dd-mon-yyyy to a "monyy", this way it doesn't become confused with the Static data in the in Oracle, and call back to the previous year when unnecessary:
TO_NUMBER(TO_CHAR(A.MV_DATE,'YYMM')) >= TO_NUMBER(TO_CHAR(SYSDATE - 365, 'YYMM'))
