Help setting up the table/list of choices

Hello:

I create an application where I use a custom authentication scheme and captures all user information in a separate table. When the user logs in he will refer to the table to identify a user name and password stored in the table.

I am allowing users to create their own user accounts that will be default to basic access levels. Further along in the process, users will need to select a person to approve something. I want to use a list of choices so that the name of the approver is entered regularly every time. The user table has the following format:

Default primary key Type Nullable data column name
Username VARCHAR2 (8) No - 1
PASSWORD VARCHAR2 (8) No. -
FNAME VARCHAR2 (30) - No.
LNAME VARCHAR2 (30) - No.
E-MAIL VARCHAR2 (50) - No.
ADMIN VARCHAR2 (1) Yes.
APPROVER VARCHAR2 (1) Yes.


I would like users to be able to choose from a list of choices that displays LNAME, FNAME. I don't know how to make the two fields appear in a list of choices.

Furthermore, I would like to (if possible) to keep the two separate fields for the creation of user accounts so that I can get a coherent LNAME, FNAME format and people are not go backwards (e.g., Smith, Joe c. Joe Smith).

If I can't show the two fields in the drop-down list, is there a way where I could add a free calculation filed to the table that will concatenate LNAME"," FNAME?

Thanks for any help you can provide.

RKD,

Create a dynamic list of values.

select lname||', '||fname displayed, username returned
from user
order by 1

You can view what you want, regardless of the value returned. And that includes the concatenation of elements together (or do other calculations/manipulations).

  • Name of the table list ALL_TABLES but not in TABS

    Hello

    I was trying to programatically check if a table is exist or not and insert the records if exist (via Java). I see a weired behaviour where when I check the metadata through my connection, I see this table_name in it (don't think there is an error in the logic), but when I try to insert a record after that, he lifts - java.sql.SQLException: ORA-00942: table or view does not exist.

    When I manually check the DB, I see this table to table ALL_TABLES but not in TABS (not sure what is the same difference between those two, and that is the right place to check), desc < table_name > is also a failure...

    I'm really confused if the table is exist or not...

    Any help is really appreciated.

  • records_per_block: can be set when the table has a lot of data?

    Hello

    We have a partition table with a length of middle line of 7K, and there are a lot of the line string. The score is based on the date, old partition will be truncated and reused later. I'm trying to find a way to limit the rows by block 1 (pct_free is another way, but is not reliable), it looks like records_per_block is a parameter that could be defined at the table level. But unfortunately, my test shows that the use of records_per_block, the table must be an empty table and insert a row inside and then set records_per_block, otherwise records_per_block will be ignored.

    A solution that is not quite perfect - alter table XXX pctfree, pctused 99 1.
    Unless your beginning of lines off incredibly short it will probably limit you to one line per block for the future DML.

    As a guideline for "ranks shortcuts" (and this may vary slightly depending on whether you use SAMS or not):

    SQL> insert into t1 values(rpad('x',42));
    
    1 row created.
    
    SQL> insert into t1 values(rpad('x',1));
    
    1 row created.
    
    SQL> select rowid from t1;

    Your analysis of the rows_per_block is not quite right — but the critical point is correct, it is very difficult to get the recorded "records per block" reduced once you have data in place. Here is an improved version of your test cut-n-pasted from a SQL * Plus term in 10.2.0.3:

    SQL> spool off
    

    I delete the last lines 36 to one block and the first 4 lines on the other. For this reason, Oracle is capable (on the block drain plug) to reduce the size of the + 'line directory' + in the first block by removing the pointers 'empty' to the end of the book - but it cannot eliminate all entries in the directory of the line of the second block because the "empty" pointers are not at the end of the directory.

    Code to determine the limit on the number of lines per block looks like the size of the largest directory online - not the current number of rows in the block.

    In my example, the largest directory of line is 33 because the last 34 entries have been pruned at the end; in your example, the largest directory of line was still 67 because your deletion had left two rows at the end of the directory.
