Using Table name in Read statement dynamically

Hi Experts,
I have the following requirement.
Based on a country code say "A" , "B", "C" and based on this i have to read different internal tables lt_tabA, lt_tabB and lt_tabC.
The table key can be given dynamically, but how can i use the internal table name dynamically without using if statements.
Please help.
Thanks!
Best Regards,
Gayathri

Hi Gayathri,
something like
DATA:
    lt_t100 TYPE TABLE OF t100,
    lt_t000 TYPE TABLE OF t000.
FIELD-SYMBOLS:
    <table> TYPE table,
    <rec>   TYPE ANY,
    <field> TYPE ANY.
SELECT:
    * INTO CORRESPONDING FIELDS OF TABLE lt_t100 FROM t100 UP TO 10 ROWS,
    * INTO CORRESPONDING FIELDS OF TABLE lt_t000 FROM t000 UP TO 10 ROWS.
CASE abap_true.
    WHEN space.
      ASSIGN lt_t100 TO <table>.
    WHEN OTHERS.
      ASSIGN lt_t000 TO <table>.
ENDCASE.
READ TABLE <table> with key ('MANDT') = sy-mandt ASSIGNING <rec>.

Use table name in UPDATE statement as variable

Hi All,
I am using ORACLE 9i AIX base. I want to write following procedure:
PROCEDURE update_header (
p_care_msg_nbr IN NUMBER,
p_care_msg_id IN NUMBER,
p_care_msg_gkey IN NUMBER,
p_old_status IN VARCHAR2,
p_new_status IN VARCHAR2
IS
l_table varchar2(50);
BEGIN
l_table := 'CARE_EDI_MESSAGES';
UPDATE '&l_table'
SET status = p_new_status,
changed = sysdate,
changer = user
WHERE care_msg_no = p_care_msg_nbr
AND care_msg_id = p_care_msg_id
AND gkey = p_care_msg_gkey
AND status = p_old_status;
END;
I want to give the table name by passing value in a variable or parameter. Is it the write way or can I do this function in any other way.
Pleae tell me in urgency.
Thanks & Regards
Hassan Raza

This implies that you have several tables with identical or near identical structures, otherwise you will get errors if any of the mentioned columns do not exist in the table passed but ...
You cannot use a substitution variable that way. Oracle will ask for a value when you try to create the procedure, and compile what ever value you supply into the procedure viz.
SQL> CREATE PROCEDURE p AS
2 l_id NUMBER;
3 BEGIN
4     SELECT id INTO l_id FROM &t;
5 END;
6 /
Enter value for t: T
old   4:    SELECT id INTO l_id FROM &t;
new   4:    SELECT id INTO l_id FROM T;
Procedure created.
SQL> SELECT text FROM user_source WHERE name = 'P'
2 ORDER BY line;
TEXT
PROCEDURE p AS
l_id NUMBER;
BEGIN
   SELECT id INTO l_id FROM T;
END;Even if that is the effect you want, note that there are no quotes around the substitution variable in the CREATE statement.
If you want to be able to pass the name of the table to the procedure, then you need to make the table name a parameter, then build the sql statement and execute it using EXECUTE IMMEDIATE. Something more like:
PROCEDURE update_header (p_care_msg_nbr IN NUMBER,
                         p_care_msg_id   IN NUMBER,
                         p_care_msg_gkey IN NUMBER,
                         p_old_status    IN VARCHAR2,
                         p_new_status    IN VARCHAR2,
                         p_table         IN VARCHAR2) IS
l_sqlstr VARCHAR2(4000);
BEGIN
   l_sqlstr := 'UPDATE '||p_table||' SET status = :b1 '||
               'changed = sysdate, changer = user '||
               'WHERE care_msg_no = :b1 and care_msg_id = :b3 and '||
               'gkey = :b4 and status = :b5';
   EXECUTE IMMEDIATE l_sqlstr
      USING p_new_status, p_care_msg_nbr, p_care_msg_id, p_care_msg_gkey, p_old_status;
END;HTH

How to use bind variable value for table name in select statement.

Hi everyone,
I am having tough time to use value of bind variable for table name in select statement. I tried &p37_table_name. ,
:p37_table_name or v('p37_table_name) but none worked.
Following is the sql for interactive report:
select * from v('p37_table_name') where key_loc = :P37_KEY_LOC and
to_char(inspection_dte,'mm/dd/yyyy') = :P37_INSP_DT AND :p37_column_name is not null ;
I am setting value of p37_table_name in previous page which is atm_state_day_insp.
Following is error msg:
"Query cannot be parsed, please check the syntax of your query. (ORA-00933: SQL command not properly ended) "
Any help would be higly appreciated.

Interestingly enough I always had the same impression that you had to use a function to do this but found out from someone else that all you need to do is change the radio button from Use Query-Specific Column Names and Validate Query to Use Generic Column Names (parse query at runtime only). Apex will substitute your bind variable for you at run-time (something you can't normally do in pl/sql without using dynamic sql)

Hi,
The wrong part is in execute immediate, it should be as follows:
execute immediate ('select count(*) from '|| c1.table_name)
into cnt

How to use table name dynamically in report procedure

Hello every body
I want to use table name dynamically means at runtime i want to pass table name.
I can do this by lexical parameter in main query.
But my problem is that i want to crate new format trigger or new function that use 1 cursor in which that lexical parameter : table name is used.
so how to do that?
i can not use that lexical parameter it is giving error.
please help me how to do that.

Call a database function which you pass the lexical parameter. Then in the database function you use dynamic sql or the execute immediate option to build the SQL string.
Return the information from this function to build your business logic on in your format trigger.

Dynamic DB table name in insert statement

In the following command i was able to build <dyn_table> dynamically but how do we do that for <dyn_wa>. table name should be populated dynamically here.
for ex: pa0001, pa0002, .... and I have these names in an IT table
INSERT <dyn_wa> FROM TABLE <dyn_table>
ACCEPTING DUPLICATE KEYS.
Pls help...Thanks

Take it as charater type.
This code works for me.
TABLES : ztest123.
DATA : tab_name(10) TYPE c.
tab_name = 'ZTEST123'.
DATA : wa LIKE ztest123.
wa-name = 'Mahesh'.
INSERT (tab_name) FROM wa.

How to find the list of un used table names in a schema?

Hi,
I have a doubt in Oracle. The doubt is that If we are using any tables in Function Or Proc.... Then...We can list all those used table names from USER_DEPENDENCIES system table. Right...
But, If the table is used with Execute Immediate Statement, then, those table names are not coming out with USER_DEPENDENCIES system table. Because they are identified at run time and not compile time.
It is fine. And I agree.. But, If I want to list out those tables also...then...How to do? Any idea?
I think ‘USER_SOURCE’ system table may not be the right one. If there is any other system table avails for this purpose...then..it would be very grateful to extract right...
So I am wanting that exact system table.
Please let me know about this, if you have any idea or check with your friends if they have any idea.
Regards,
Subramanian G

Hi Guys,
Thanks for all your answers.
Yes....You are all right. We can list out the used tables upto certain extent. Anyhow, I have done some R&D to derive the SQL's which is given below:
SELECT TABLE_NAME FROM USER_TABLES
MINUS
SELECT DISTINCT UPPER(REFERENCED_NAME)
FROM user_dependencies
where
referenced_type='TABLE' and UPPER(NAME) in
select distinct UPPER(object_name) from user_objects where UPPER(object_type) in
'MATERIALIZED VIEW',
'PACKAGE',
'PACKAGE BODY',
'PROCEDURE',
'TRIGGER',
'VIEW',
'FUNCTION'
UNION
SELECT UT.TABLE_NAME FROM
SELECT TABLE_NAME FROM USER_TABLES
MINUS
SELECT DISTINCT UPPER(REFERENCED_NAME)
FROM user_dependencies
where
referenced_type='TABLE' and UPPER(NAME) in
select distinct UPPER(object_name) from user_objects where UPPER(object_type) in
'MATERIALIZED VIEW',
'PACKAGE',
'PACKAGE BODY',
'PROCEDURE',
'TRIGGER',
'VIEW',
'FUNCTION'
AND REFERENCED_OWNER=(SELECT sys_context('USERENV', 'CURRENT_SCHEMA') FROM dual)
) UT,
( SELECT * FROM USER_SOURCE
WHERE NAME IN
( SELECT DISTINCT NAME FROM USER_SOURCE
WHERE TYPE NOT IN ('TYPE')
AND
UPPER(TEXT) LIKE '%EXECUTE IMMEDIATE%'
) US
WHERE
UPPER(US.TEXT) LIKE '%'||UPPER(UT.TABLE_NAME)||'%'
AND
(UPPER(US.TEXT) NOT LIKE '%--%')
The above SQL Query can list out unused tables by checking the Dynamic SQL Statement also upto some level only.
Once we extracted the list of unused tables, having a manual check would be also greater to verify as it is should not impact the business applications.

Dynamically assigning table name in select statement

how can i assign the table name dynamically in Select statement?
i tried following code
create or replace procedure proc1
as
x varchar2(100);
y varchar2(10);
begin
x='UNIT_MASTER';
execute immediate 'select unit_code into y from x where
rownum=1';
dbms_output.put_line(y);
end;
the procedure is created but when i execute the procedure the
error is shown in the execute immediate statement

Do the following :
Create or replace procedure pro1 as
x varchar2(100);
y varchar2(10);
begin
x := 'UNIT_MASTER';
EXECUTE IMMEDIATE 'select unit_code from '||x||' where rownum
= 1' INTO y;
dbms_output.put_line(y);

ODI: Using Table Name in Dynamic filters

We have a requirement, where the filters have to be dynamically generated and applied on the source system data stores.
The requirement can be best explained by the below example.
I have EMPLOYEE and DEPARTMENT table as the source datastores and EMP_DEPT (flat table) as the target datastore.
The filter condition will be updated now and then by the admin in a table. They would like to run the integration interface with the condition mentioned in the table.
Metadata table and sample data: (DY_FILTERS)
TABLE_NAME | INTERFACE_NAME | CONDITION
EMPLOYEE | EMP_DEPT | EMPLOYEE.EMPLOYEE_NAME LIKE 'A%'
DEPARTMENT | EMP_DEPT | DEPARTMENT.DEPARTMENT_ID = 10
So now the interface has to run with the conditions 'EMPLOYEE.EMPLOYEE_NAME LIKE 'A%' and DEPARTMENT.DEPARTMENT_ID = 10.
To achieve, the best possible solution I can think of is, I have defined a variable for the dynamic filter and under the refresh section and I am planning to use the following query:
SELECT CONDITION FROM DY_FILTERS WHERE INTERFACE_NAME = <%=odiRef.getPop("POP_NAME")%> AND
TABLE_NAME = ***************.
I was able to pick the interface that is currently involved by using getPop() method where as I dont have clue for getting the table name.
Please share with me, if you have answer. Also if you have any other way to achieve this, please share the same.
Note: The actual scenario is more complex than the example given above. But the crux of the requirement is very well covered in the example.
Edited by: 986046 on Feb 14, 2013 2:06 PM

Hi,
If you've only one source datastore in your interface, you can retrieve it's name with <%=odiRef.getSrcTablesList("[RES_NAME]", "")%>.
If you have more than one source it will list all you sources.
However I can't see when you plan to refresh your variable. getSrcTablesList won't work before/after the interface execution.

How to use table name as variable in insert statement

Hi,
I want to insert data from the cursor into the table and I want to submit table name as a variable. I tried the code below but it's not working. Any ideas how to solve this problem? Thx
DECLARE
v_new_table_name VARCHAR2(30) := 'test';
--open cursor
CURSOR ACM IS
SELECT *
FROM DWH.CLI_DIMENSION@SLSPDW CLI
WHERE where_clause
FROM some_table;
BEGIN
FOR REC_ACM IN ACM LOOP
EXECUTE IMMEDIATE 'INSERT INTO ' || v_new_table_name || ' VALUES REC_ACM'; --table name as a variable in which the data from cursor will be inserted
V_ROWCOUNT := V_ROWCOUNT + 1;
IF MOD(V_ROWCOUNT, 100) = 0 THEN --this feature commits after 100 rows.
COMMIT;
END IF;
END LOOP;
COMMIT;
DBMS_OUTPUT.PUT_LINE('Number of inserted records:' || V_ROWCOUNT);
END;

Try this and let me know if it works. I have not tested it so I can not say for sure.
DECLARE
v_new_table_name VARCHAR2(30) := 'test';

    SELECT * FROM DWH.CLI_DIMENSION@SLSPDW CLI

   fetch ACM INTO REC_ACM
   exit when ACM%NOTFOUND;
   EXECUTE IMMEDIATE 'INSERT INTO ' || v_new_table_name || ' VALUES REC_ACM';
   V_ROWCOUNT := V_ROWCOUNT + 1;
   IF MOD(V_ROWCOUNT, 100) = 0 THEN
    COMMIT;
   END IF;
end loop;

How user variable table names in select statement

Dear all,
I have three table gp1,gp2,g3. i want user variable table in sql query
for example at oracle forms have a list table showing table names gp1,gp2,gp3
at form i want user this query
select gpno from :table where gpno=120;
how i can specify table name Dynamicly in select query
Thanks

Forms_DDL is a one-way street: You can only pass DDL commands TO the database; you cannot get data back using Forms_DDL.
Exec_SQL is the Forms package that enables dynamic sql within a form. But to retrieve data, you have to make a Exec_SQL call for every column in every row. So it is not a good thing to use, either.
The ref cursor method should work. You could also retrieve the data into a record group using populate_group_with_query -- it also enables dynamic data retrieval.
But if you already know you have three distinct tables and you know their names, I would keep it simple and just write three sql select statements.

Invalid table name when pass in the table name as variable in dynamic sql

Hi,
I need to create a stored procedure which will return a list of data to my java application like the following.
first, select the table name from the first table.
For example : SELECT T_NAME FROM MDR_SMSTABLES
second, select the data from the table which returned by first select statement
For example : SELECT * FROM T_NAME.
I use dynamic sql with cursor to select the data. But it returns "java.sql.SQLException: ORA-00903: invalid table name"
I fetch the table name to varchar2. I think this might the cause it returns me the this error. But i don't know what type should i put for the table name other then varchar2.
val2 VARCHAR2(200);
OPEN cv FOR
SELECT T_NAME FROM MDR_SMSTABLES WHERE T_DATE=d_dt_sent;
FETCH cv INTO val2;
WHILE cv%FOUND
LOOP
OPEN refcur FOR
'SELECT * FROM :t WHERE MID = :m' USING val2, msg_id;
EXIT WHEN refcur IS NOT NULL;
FETCH cv INTO val2;
END LOOP;
As my stored procedure is quite long, so i just paste some of the code here. Hope the information is enough. Can anyone please help?
Thanks

DECLARE
val2 VARCHAR2 (200);
cv sys_refcursor;
refcur sys_refcursor;
BEGIN
OPEN cv FOR
SELECT table_name
FROM user_tables
WHERE table_name IN ('EMP', 'DEPT');
FETCH cv INTO val2;
WHILE cv%FOUND
LOOP
OPEN refcur FOR 'SELECT * FROM '||val2;
EXIT WHEN refcur IS NOT NULL;
FETCH cv INTO val2;
END LOOP;
END;

How to find table name(s) in a dynamic query

In one of our (9iAS PORTAL)applications, any user can able to run their query statment and get output. All queries will be executed as dynamic SQL thru' a common shema/user who has 'SELECT' privilege on all tables but all users don't have this privilege on all tables. Now, before executing any query I need to find out what are the table name(s) used in this query to check the privilege for the respective user. How do I extract all table names being used in a dynamic query?.
Thanks
-Krishnamurthy

I guess that his users log in to application first, then application uses one account to log in to database, so application are not direct database user since all users share the same account to database. If so, when a user lgins in, you may write it down from application to a database audit table, and you need to write down the dynamic query to the database audit table too, then you may query that audit table to find out. up to here, it looks that your application has to do more to assign what role to a user running the application, since database does not know what user is assessing it.

How to insert variable for table name in Select statement ?

I am creating a stored procedure which will take two table names as IN parameters. Within the procedures I would like to use the parameters in the following manner;
     SELECT count(*)
     INTO v_target_cnt
     FROM TargetTable;
TargetTable is one of the parameters passed in. When I do this however it does not recognize the parameter. I have tried assigning the parameter to a local variable and using the variable, with not luck.
Any help....thanks

Null,
What you are describing is called a LEXICAL parameter, which is allowed (preceded by an ampersand) in sql but not in pl/sql because it would not be possible to compile it. That is why you need to use Andrew's suggestion to make the sql dynamic. In older versions you would need to use DBMS_SQL which is horrible and now thankfully redundant.
