I am trying many possiblities but without any success. any1 knowling please let me know.
Regards,

well, depending on the requirments you can use XML to some extent:
SQL> var name varchar2(20);
SQL> exec :name:='scott.emp';
PL/SQL procedure successfully completed.
SQL> select 'Table "'||:name||'" has ' ||
2         extractvalue(dbms_xmlgen.getXMLType('select count(*) cnt from '||:name),
3                      '//CNT') || ' rows'
4    from dual;
'TABLE"'||:NAME||'"HAS'||EXTRACTVALUE(DBMS_XMLGEN.GETXMLTYPE('SELECTCOUNT(*)CNTF
Table "scott.emp" has 14 rows
SQL> exec :name:='all_tables';
PL/SQL procedure successfully completed.
SQL> select 'Table "'||:name||'" has ' ||
2         extractvalue(dbms_xmlgen.getXMLType('select count(*) cnt from '||:name),
3                      '//CNT') || ' rows'
4    from dual;
'TABLE"'||:NAME||'"HAS'||EXTRACTVALUE(DBMS_XMLGEN.GETXMLTYPE('SELECTCOUNT(*)CNTF
Table "all_tables" has 1622 rows

SQL or PL/SQL : dynamically insert table name in a SQL Statement

Hi,
We have a strange requirement - we need to dynamically use the table names in a SQL Query. E.g:
select * from :table_name
The table_name will be chosen from a list. I have tried this in SQL as well as PL SQL - but, I have been unsuccessul so far.
Can you guys please help me solve this puzzle ?
I hope I have explained my quesion clearly - if not, please do let me know if some more details are necessary.
Regards,
Ramky

The following is the anonymous block that im using in a report in HTMLDB. My problem is Line Number 9. The bind variable contains the chosen table name at
the run time.
Variable "qry_stmt" contains the query to be returned, so that result set for that query will be displayed in the report.
If I hard code the table name(rather that passing it through bind variable) in the
qry_stmt string, Im getting the result sets for that query. But if I pass through
bind variable at run time, its still generating the string correctly( im printing
using a print statement at line number 14). But its returing the following report
error
report error:
ORA-01403: no data found
Please advice/help me in this.....
declare
qry_stmt varchar2(1000);
p_table varchar2(30) := 'EMP';
P_ENAME varchar2(1000);
begin
IF :p2_TABLE_NAMES IS NOT NULL THEN
qry_stmt := 'select * from '||TRIM(:P2_TABLE_NAMES); -- Line Num 9
execute immediate qry_stmt; --into P_ENAME;
ELSE
qry_stmt := 'SELECT 1 FROM dual ';
END IF;
htp.p(qry_stmt);--Line Num 14
return qry_stmt;
EXCEPTION WHEN NO_DATA_FOUND THEN
NULL;
end;

Parse SQL: How to extract column names, table names from a SQL query

Hi all,
I have a requirement wherein a SQL query will be given in a text file.
The text file has to be read (probably using text_io package), the SQL query needs to be parsed and the column names, table names and where clauses have to be extracted and inserted into separate tables.
Is there a way to do it using PL/SQL ?
Is there a PL/SQL script available to parse and extract column names, table names etc ?
Pls help.
Regards,
Sam

I think I jumped to conclusion too early saying it is completely possible and straight forward. But after reading through your post for one more time I realised you are not interested only in the column_names, also the table_names and the predicates .
>

>
The above is possible and straight forward using the dbms_sql package.
I am pasting the same information as I did in the other forum.
Check this link and search for Example 8 and .
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_sql.htm#sthref6136
Also check the working example from asktom

>

>
Now this is the tricky bit. You can extract the list of tables by getting the sql_id from v$sql and joining it with v$sql_plan. But sometimes you may not get all the results because the optimizer may choose to refine your query (check this link)
http://optimizermagic.blogspot.com/2008/06/why-are-some-of-tables-in-my-query.html
and you can get the predicate information from the same table v$sql_plan but I will leave that area for you to do some R&D.

Using variable as table name in pl/sql query - Is possible?

I am relatively new to PL/SQL and I am trying to create a function that accepts a table name and a rowid as arguments and returns a comma-delimited record string of the values of the table/rowid being passed. The problem is , I cannot code a select stmt as follows
SELECT * FROM v_table_name
WHERE rowid = v_row_id
in PL/SQL. There must be a easy way to approach this.
Thanks for any and all advice.
GC

I don't understand the use of the concat symbol along with the commas and field namesYou just need (if you really need it) to create variable which contains you column separated by comma:
Simple example (in the second case separate variables are used to create
the list of columns):
SQL> declare
2   rc sys_refcursor;
3   cols varchar2(200) := 'ename, empno, sal';
4   tab varchar2(30) := 'emp';
5 begin
6   open rc for 'select ' || cols || ' from ' || tab;
7   close rc;
8 end;
9 /
PL/SQL procedure successfully completed.

Dynamic table names without dynamic sql?

I am trying to figure out a way to use table names as variables without using dynamic sql.
So for instance, I have...
execute immediate 'INSERT INTO '||vTABLE||' VALUES ('test')';
and
execute immediate 'INSERT INTO TABLE1 SELECT * FROM '||vTable;
Is there any other way to do these without the dynamic sql in Oracle 10.2g?

I am trying to figure out a way to use table names as variables without using dynamic sql. Well I guess it makes a change from perpetual motion machines or cold fusion.
Are you doing this as a purely academic exercise or do you have something against dynamic SQL?

Use a variable as a table name with NATIVE SQL

Hi all,
I am trying to execute a SELECT statement in order to fetch data from an external Oracle DB table to SAP with the following instructions:
EXEC SQL.
SELECT cityfrom, cityto
         INTO STRUCTURE :wa
         FROM spfli
         WHERE mandt = :sy-mandt AND
               carrid = :p_carrid AND connid = :p_connid
ENDEXEC.
However, I need to indicate the external table name from a variable instead of the solution above. That is, declaring a variable and store the name of the table (e.q. spfli) in it. The resulting ABAP code would be something like:
EXEC SQL.
SELECT cityfrom, cityto
         INTO STRUCTURE :wa
         FROM <VARIABLE>
         WHERE mandt = :sy-mandt AND
               carrid = :p_carrid AND connid = :p_connid
ENDEXEC.
Does anybody know if is possible to do that?
If not, is there any other solution?
Thank you in advance

Yes, as Suhas said, you could use the ADBC API and his class CL_SQL_CONNECTION to achieve this...
Here is a small example:
PARAMETERS: p_carrid TYPE spfli-carrid,
                           p_connid TYPE spfli-connid.
DATA:
l_con_ref      TYPE REF TO cl_sql_connection,
l_stmt         TYPE string,
l_stmt_ref     TYPE REF TO cl_sql_statement,
l_dref         TYPE REF TO data,
l_res_ref      TYPE REF TO cl_sql_result_set,
l_col1         TYPE spfli-carrid,
l_col2         TYPE spfli-connid,
l_wa           TYPE spfli.
CONSTANTS:
c_tabname TYPE string VALUE 'SPFLI'.
* Create the connecction object
CREATE OBJECT l_con_ref.
* Create the SQL statement object
CONCATENATE 'select * from' c_tabname 'where carrid = ? and connid = ?'
       INTO l_stmt SEPARATED BY space.                           "#EC NOTEXT
l_stmt_ref = l_con_ref->create_statement( ).
* Bind input variables
GET REFERENCE OF l_col1 INTO l_dref.
l_stmt_ref->set_param( l_dref ).
GET REFERENCE OF l_col2 INTO l_dref.
l_stmt_ref->set_param( l_dref ).
* Set the input value and execute the query
l_col1 = p_carrid.
l_col2 = p_connid.
l_res_ref = l_stmt_ref->execute_query( l_stmt ).
* Set output structure
GET REFERENCE OF l_wa INTO l_dref.
l_res_ref->set_param_struct( l_dref ).
* Show result
WHILE l_res_ref->next( ) > 0.
WRITE: / 'Result:', l_wa-carrid, l_wa-connid.
ENDWHILE.
* Close the result set object
l_res_ref->close( ).
Otherwise you can also use the FM DB_EXECUTE_SQL...

How to use a variable as a table name in PL/SQL?

Hello all.
I was given one day to wrote a piece of PL/SQL code to do a query. That is,
First select two columns from one table and use them to build another table's name, then
     join the two tables. I'm not sure if variables can be used in the select list, if possible,
     how to reference them?
-- My code is
DECLARE
     tablename varchar2(40);
     CURSOR c1 IS
select a.sourcesystemcode, a.adminorganizationno from cdb1.organization_mapping a
where exists( select 1 from cdb1.organization_mapping b where
a.cdborganizationno = b.cdborganizationno and a.adminorganizationno != b.adminorganizationno)
order by a.cdborganizationno,a.adminorganizationno;
     v_src_sys_cod cdb1.organization_mapping.sourcesystemcode%TYPE;
     v_adm_org_no cdb1.organization_mapping.adminorganizationno%TYPE;
BEGIN
OPEN c1;
LOOP
FETCH c1 INTO v_src_sys_cod, v_adm_org_no;
EXIT WHEN c1%NOTFOUND;
tablename := 'ODS1.SRC_' || v_src_sys_cod || v_adm_org_no || 'ACTORG_CURR';
select c.cdborganizationno, c.sourcesystemcode, c.adminorganizationno, c.sourceorganizationno, d.ibkcde, d.orgnam
from cdb1.organization_mapping c inner join tablename d on c.sourceorganizationno = d.orgidt;
END LOOP;
CLOSE c1;
END;
The error message says "... the table or view does not exist... line 18, column 66..."
It says the variable "tablename" wasn't build or build incorrectly.
Please give the solution.

If the TABLEs being queried are already known, and it is just a matter of which one to query, perhaps you can CREATE a VIEW that uses all the TABLEs with a UNION ALL, and include an identifier COLUMN.
CREATE VIEW SRC_ALL_ACTORG_CURR
AS
SELECT 'aa' Name, ibkcde, orgnam FROM SRC_aa_ACTORG_CURR UNION ALL
SELECT 'bb' Name, ibkcde, orgnam FROM SRC_bb_ACTORG_CURR UNION ALL
SELECT 'cc' Name, ibkcde, orgnam FROM SRC_cc_ACTORG_CURR UNION ALL
SELECT 'dd' Name, ibkcde, orgnam FROM SRC_dd_ACTORG_CURR UNION ALL
SELECT 'ee' Name, ibkcde, orgnam FROM SRC_ee_ACTORG_CURR;
Then, in you query:
select c.cdborganizationno, c.sourcesystemcode, c.adminorganizationno, c.sourceorganizationno, d.ibkcde, d.orgnam
from cdb1.organization_mapping c inner join SRC_ALL_ACTORG_CURR d on c.sourceorganizationno = d.orgidt and d.Name = v_src_sys_cod || v_adm_org_no;

Sql statement for a table name with a space in between

Hi,
I just noticed that one of my tables for Access is consisted of two word. It is called "CURRENT CPL". How would I put this table name into an sql statement. When I did what I normally do, it only reads the CURRENT and thinks that's the table name.
Thanks
Feng

I just noticed that one of my tables for Access is
consisted of two word. It is called "CURRENT CPL".
How would I put this table name into an sql
statement. When I did what I normally do, it only
reads the CURRENT and thinks that's the table name.That is called a quoted identifier. The SQL (not java) for this would look like this....
select "my field" from "CURRENT CPL"
The double quote is the correct character to use. Note that quoted identifiers are case sensitive, normal SQL is not.

Bug With Quoted Table Names?

I think I've encountered a bug in Oracle 9.2.0.1.0. If I create table with its name in quotes, I can't access it again unless I also use the name in quotes. But, in DBA_OBJECTS the table's name shows up without quotes.
For example:
CREATE TABLE "avalys" (test number);
SELECT * FROM "avalys"; --Works
SELECT * FROM avalys; --Doesn't
Any idea what the problem could be? Am I just not supposed to quote table names (I need to, because one of our tables is a reserved word, and unfortunately we can't change the name of the table).

When you put quotes around a table name, you're telling Oracle to store the table name in a case-sensitive fashion, rather than the default case-insensitive fashion. When you use a non-quoted identifier, Oracle automatically upcases the whole thing and tries to resolve the name. Thus, you can do the following (not the uppercase table name in quotes)
SQL> create table "FOO" (n1 number);
Table created.
SQL> select * from foo;
no rows selected
because "select * from foo" implicitly upcases foo. If you declare a table with some lowercase letters, i.e.
SQL> create table "FOo" (n1 number);
Table created.
you'll only be able to access it with the same partially lowercase string, i.e.
SQL> select * from "FOo"
no rows selected

Getting table name from a query

Hi, I'm trying to get the table name from my sql query
My code is as follows;
ResultSetMetaData metadata = rs.getMetaData();
for (int i = 1; i < metadata.getColumnCount(); i++)
System.out.println(metadata.getTableName(i));
I just get a blank output. Yet my sql query executes and I can pull down the records, and grab the column names from the result sets.
Any ideas on how I can get the table name for the columns. The reason being is on one of my querys I'm using join statements and i need to retrieve the table name for the column i'm displaying, as some tables have similar column names.
Thanks in advance.

Hi,
What db are you using?
I also get a blank output with ResultSetMetaData.getTableName because Oracle doesn't implement this method.
Why do you not know the table name anyway?
regards
Nick

PreparedStatement and table name

Hi,
I have the following snippet, and it seems that I cannot use the function
prepStmt.setString(1, TABLE_NAME);
to set the table name for the SQL prepared statement. What function should I use?
Thanks,
Rocky
final String[] TABLE_NAME =
"Borrower",
"Loan",
"Depositor",
"Account",
"Customer",
"Branch",
final String DATA_DELETE = "DELETE * FROM ?";
try
PreparedStatement prepStmt = dbConn.prepareStatement(DATA_DELETE);
for (int i =0; i < TABLE_NAME.length; i++)
System.out.println(TABLE_NAME[i]);
prepStmt.setString(1, TABLE_NAME[i]);
prepStmt.execute();
prepStmt.clearParameters();
dbConn.commit(); // not needed
prepStmt.close();
catch(SQLException e)
System.out.println(e.getMessage());

setString is just a specific case of setting a field value should not be used to set table name
what u want to do should be done at the sql String level and it's not necessary prepared statements
This would be my suggestion (didn't test it):
final String[] TABLE_NAME =
"Borrower",
"Loan",
"Depositor",
"Account",
"Customer",
"Branch",
final String DATA_DELETE = "DELETE * FROM TABLE_NAME";
try
Statement stmt = dbConn.createStatement();
for (int i =0; i < TABLE_NAME.length; i++)
System.out.println(TABLE_NAME);
stmt.executeUpdate(
sql.replaceFirst("TABLE_NAME",TABLE_NAME[i])
dbConn.commit(); // not needed
stmt.close();
catch(SQLException e)
System.out.println(e.getMessage());
