Finding columns names in a ResultSet

Hi,
Is it possible to get the columns names in a ResultSet ?
After a SQL query, while parsing the ResultSet List, I would like to detect the columns names used in the select processed. Is it possible ?

Hi,
Take a look at the method:
public ResultSetMetaData getMetaData() in the ResultSet.

Finding column name in database

Hi all..
I want to find each column name, how many tables this column name is there
in database.
For single colum, i can find by using this query..
select a.COLUMN_NAME, a.TABLE_NAME from all_tab_columns a where
a.OWNER='DC_ERD' and a.COLUMN_NAME ='ACCESSORY_MAKER'
If i want to find for each column present in the database, can anybody please tell
me if it is possible in sql or pqsql is needed.
Thanks in advance,
Pal

Are you asking about the number of tables, it's been used or the tables list?
select column_name, count(table_name)
from all_tab_columns
group by column_nameCheers

How to find column names in a table

Am learning the basics of SQL Plus.
Have entered the following query:
SELECT * FROM t_ebb_session;
This gives me the following output.
USER_ID SESSION_ID LAST_ACCE
However LAST_ACCE is not the full name of the column as I get 'Invalid column name when I use it in a select statement.
How do I display the full name?

By default, SQL*Plus will set the column display width of a character column to its size in the database, and the heading will be the column name in uppercase, truncated to fit that width if necessary. (There is a different rule for numeric columns.)
You can override this with the COLUMN command, e.g:
COLUMN some_column_name FORMAT a30 HEADING "Alternative Name"
Check out the SQL*Plus documentation for all the COLUMN options.

Finding column Name in structure

Hi All
I have a requirement where i have the field names ( matnr, ekorg) etc., in an intenal table. eg., . using those names I need to read another internal table which carries values for the fields. I need to write a program to check if a particular field in table 1 has an initial value in table 2 or not.
for my logic, I am looping on tab1( since it will contan only few fields) and assigning it to field symbols. but since the values from tab1 are dynamic, i cant hard code to assign field name like Matnr. So I am unable to figure out who to read tab2 with the field names i find in tab1.
I used cl_abap_tabledescr=>describe_by_data (itab2) to columize the fields of itab2. but this method doesnt fetch me the field values? I was wondering if my approach was correct and if there is any way to use fields from itab1 to read values from itab2.
I am not an ABAP expert, so any help is appreciated
Regards
Ruel

Hi,

Column name problem

Hi all.... I have a little strange problem.. I hope you all can help me in solving this.
for brief intro, I have an web application on MySQL written entirely in JAVA. Now we want to migrate from MySQL to Oracle... We have used Oracle Migration Workbench for migrating Schema and data. There is no problem uptill now.
The real problem is with the column names... to clear the problem lets have an example...
In mysql, if you execute[b] 'Select employeeID,empName from employee' you will always get 'employeeID' and 'empName' column names in the resultset meta data... but if you executes the same query on oracle you will get 'EMPLOYEEID' and 'EMPNAME' column names in resultset meta data... then we make some xmls using these column names and then parse them and get values using HashMap... now in hashmap 'a' is different from 'A'... We did not take care of this problem while building this application. Now the application is almost completed and we are just one step away from migrating to Oracle but this problem is hindering us.
just keep in mind there are several jsps,java beans, java services working on DB. So we need such a solution to apply on oracle and get our desired column names back from result set meta data.
I have tried multiple solutions for this.
1. Synonyms.. but you can only create synonyms for table not for column names
2. Create table with double qoutes... but then we have to change all our queries which requires a lot of files to change.
3. Create Views.... but it has same problem as of point 2.
Can you suggest any better way to work around this problem... which require minimum effort and we migrate to oracle with existing code... Otherwise we have to do a lot of donkey work to change the code...
Thanks in advance

As others have said, the SQL standard as well as several implementations do not support mixed- or camel-case identifiers. IN addition, only 8 character identifers are required, all else is 'above the standard'. You are facing a typical porting issue.

Finding source database table/column name for a column in a view

Hi i need to be able to identify the original database table/column name for a column in a view.
e.g. say i have a view like this
create v1 as select a.name fname, b.name bname, c.name cname,......
from u1.names a, u2.names b. u3.names c
where .....
Now I want to find out that the database table/column name for the fname, bname and cname columns in the view v1, which in this instance is u1.name.name, u2.names.name, u3.names.name.
But i need to be able to do it for any view. Short of parsing the SQL is there an easy way of doing this?
Now obviusly I can't do this for virtual columns but I will know my column is not virtual as it has an index on it.

But i need to be able to do it for any view. Short of
parsing the SQL is there an easy way of doing this?No, parsing the SQL is the only way. Good luck it is not something I would want to attempt.

Finding column and table name

Hi,
I need to find out that '101c_0000000018' value is which column and table of database.
Is there a way to find it? I am looking for table and column which is storing this data.
Thanks
Sandy

It's possible but performance is going to be horrible.
Assuming the data is stored in a CHAR or VARCHAR2 column, something like
DECLARE
l_value VARCHAR2(100) := '101c_0000000018' ;
l_cnt   PLS_INTEGER;
l_sql    VARCHAR2(1000);
BEGIN
FOR x IN (
      SELECT table_name, column_name
        FROM dba_tab_cols
       WHERE owner = <<name of schema>>
         AND data_type IN ('CHAR', 'VARCHAR2' )
LOOP
    l_sql := 'SELECT COUNT(*) FROM ' || x.owner || '.' || x.table_name || ' WHERE ' || x.column_name || ' = :1';
    EXECUTE IMMEDIATE l_sql
      INTO l_cnt
     USING l_value;
    IF( l_cnt > 0 )
    THEN
      dbms_output.put_line( 'Found the value ' || l_value || ' in owner = ' || x.owner || ' table name = ' || x.table_name || ' column name = ' || x.column_name );
    END IF;
END LOOP;
END;Justin

Column exist but ResultSet.getString(String) return invalid column name

With oracle 7 db the ResultSet.getString(String) works fine but after the upgrade to oracle 8 db it return invalid column name. ResultSet.getString(int) method works fine.
Is this a bug in the driver?
Thanks
-Reda

Yes I'm 100 % sure that the columns exist.
-RedaWell then maybe it's a bug in the Oracle driver. Lord knows it wouldn't be the first time that's happened.

"invalid column name" using resultset.getString()???

I had a sql query against oracle db:
select table1.field1, table1.field2, table2.field3
from table1, table2
where table1.field1=table2.field1;
i got a valid resultset and i can enum the resultset by rs.getString(colnum). However, when i try to use rs.getString(table1.field1), i get a sql exception: "invalid column name". has anybody seen this before?
TIA

Hi,
You can also modify your query and use the keyword "As" to give your fields another name :
select user.name as userName, admin.name as adminName
from user, admin
rs.getString("userName");
rs.getString("adminName");
