Short table name in SELECT statement

Does Oracle support anything like the following sintax:
SELECT * FROM TABLE1 AS T1
Thanks in advance

syntex use like....
create table T1 select * from T2.
test@ORA10G>
test@ORA10G> create table t2 (x number);
Table created.
test@ORA10G> create table T1 select * from T2;
create table T1 select * from T2

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)

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.

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);

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.

Is it Possible to join 4 or more tables in a Select Statement?

Hello guys,
Can I do Inner Join 4 or 5 tables in a select statement?

U HAVE TO SERCH FOR KEY FIELD FOR THAT . MEANS   HOW TABELS ARE RELATED EACH OTHE FOR THIS U ALSO USE SQ02
FOR EXAMPLE
SELECT        bkpf~belnr
                bkpf~gjahr
                bkpf~bukrs
                bkpf~blart
                bkpf~bldat

U CAN ALSO ADD   MORE TABLE BASED ON CONDITION

Need a that Table Name in Select command which being used in from statement

My Question Is:
If my SQL command is like this "
Select Code, Name from Customer (Table Name)
Can I get this output in this Way .. ?
Select Code, Name,Customer(Table Name) from Customer (Table Name)
in dynamic way ..

NO. You missing many fundamental concepts of RDBMS. A table is a set of entities, so it's name is plural or collective(unless you really do have only one customer as you said). There is no such thing as a generic "name", or "code" in RDBMS. Those affixes
are called attribute properties, and they have to be part of an attribute data element name -- customer_name, postal_code, etc.
Since a table is a set, its columns are fixed and known in the schema. They do not change by magic! This kind of non-RDBMS thinking is called "Automobiles, Squids and Lady GaGa" coding. Please read any intro book on RDBMS. Your whole mindset is wrong.

Short dump with a select statement

I have the following select statement (I have also inluded my data statement(s)) and I get a short dump. The error is as follows:
<b>What happened?
    Error in ABAP application program.

Dynamic table name in select statment

hai,
Please help me....
oracle 9i i am using.
i have four tables abc_121,
abc_122,
abc_123,
abc_124.
i want to pick records from a table.table name should be prepared dynamically.
i.e., i want to pick records from a quarter table of this year.(ex: abc_124). using sql statement only.
i have tried..but i couldn't...... pls help me...

i.e., i want to pick records from a quarter table of this year.(ex: abc_124). using sql statement only.Create a partition view. E.g.
create or replace view abc as
select * from abc_121
union all
select * from abc_122
union all
...For the partition view approach to correctly work (doing "partition pruning"), you need to have a constraint on the column that identifies that partition.
In other words, you cannot use the table name as an attribute to identifies its data content. Foe example, you can have tables YEAR2001_Q1 and YEAR2001_Q2. However, the year and quarter also need to be in the table itself - e.g. columns YEAR and QUARTER.
For table YEAR2001_Q1, the YEAR column needs to have a check constraint that ensures it is always 2001. And a check constraint for column QUARTER to ensure that it is always 1.
If these conditions are met, then a select from the partition view using +"where YEAR=2001 and QUARTER=2"+ will result in only table YEAR2001_Q2 to be used and not other tables like YEAR2001_Q1.

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!

    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;

Specify schema name in select statements

Is there a way to specify the schema name for the connection so that I don't have to specify schema name with every statement?
Currently I am executing the statement:
Statement stmt = null;
ResultSet rs = null;
String getAllNames =
"SELECT NAME FROM " + schemaName +".NAMES " + schemaName +" WHERE STATUS_CODE != 12 ";
stmt = conn.createStatement();
rs = stmt.executeQuery(getAllNames);
But I have a lot of such statements, a few which uses parameters.
Is there a way I can specify the schemaName once and for all so that I don't have to perform string concat everytime the function is invoked.

well I tried that, since the application runs under CICS which uses the trusted connection with DB2, all CICS application will be using the same userid and there is no way to ensure that other applications would not be using the same table name in some other application. So the only option I have is to specify the schema name with the select statements but I don't want to append the schema name with each statement.

Cannot use alias for dynamic column name in SELECT statement

Hi,
I want to retrieve values from several tables by using dynamic column & table name as below:
DATA: tbl_name(30) TYPE c VALUE '/bic/tbi_srcsys', " staticly initialized for this example
col_name(30) TYPE c VALUE '/bic/bi_srcsys'. " staticly initialized for this example
SELECT (col_name) INTO CORRESPONDING FIELDS OF TABLE it_values FROM (tbl_name).
The internal table "it_values" does not contain a field named "/bic/bi_srcsys", instead it has another generic field "value" so that the above code can be applied to other tables. I tried to use alias (AS) as below:
SELECT (col_name) AS value INTO CORRESPONDING FIELDS OF TABLE it_values FROM (tbl_name).
But this cannot work. I know that there are other ways to solve this problem, such as by using a single field in SELECT .. ENDSELECT and subsequently appending it to the work area and internal table as below:
SELECT (col_name) INTO (lv_value) FROM (tbl_name).
wa_value-value = lv_value.
APPEND wa_value TO it_values.
ENDSELECT.
Just wonder if there is any other more elegant workaround, because I might have several other fields instead of only one?
Thanks.
Regards,
Joon Meng

Hi Suhas,
thanks for the quick reply.
Sorry that I have not well described the structure of the internal table "it_values". This internal table contains several other fields (key, type, value, etc.).
I guess that the following code
SELECT (col_name) INTO TABLE it_values FROM (tbl_name).
works if the internal table only has one field (value) or the field "value" is in the first position, right?
In this case, I need to fill the "value" field of internal table it_values (ignore the other fields like type, key) with values retrieved from (col_name) of the DDIC table.
Looking forward to your reply.
BR,
Joon Meng
