Joining table using CHAR and VARCHAR data type as indicator

Hi All,
I would like to join 3 tables together but I'm unable to get a perfect concordance (using =) between CHAR and VARCHAR data type.
Does a command exist to get impartially all data treated as CHAR or VARCHAR ?
Thanks in advance for your help !

You want the database to perform with such a crappy database design? Good luck with that.. Instead, you need to look at why you are NOT using surrogate integer based keys for your data tables..
Thank you,

Char and varchar performance issues

I am creating a child table with varchar2(4) column which takes the value from parent table which has char(4) column.
pls give ur suggestion that child table also should have char(4) as like parent table or having varchar2(4) is good one.? which one gives better peformance?

Whats the difference between CHAR and VARCHAR2 data type?
CHAR is a fixed length data type and VARCHAR2 is a variable length. What does that mean? Lets say you have a CHAR(4) and VARCHAR2(4) column. You are storing the word 'AA' in both. Oracle will allocate 4 byte of space for CHAR column and just 2 byte of space to VARCHAR2 column. i.e. as i already said CHAR is a fixed length string. So the 'AA' is actually stored as 'AA ' (AA<two blank spaces>).
So the next question is which of the two is better? You cant compare them, they are just two different tools provided by oracle. Use which is best suited for you.

The conversion of a varchar data type to a datetime data type resulted in an out-of-range value

The Best thing in Life is Life

Since the Variable
BLDCHKDT and BLDCHTIME are of type date time why are you trying to assign it a value
of type varchar
and the format 105 gives you dd-mm-yyyy but SQL server takes the default format as mm-dd-yyyy so the error occurs for all dates that
are greater than 12
try the below code
Declare
@hdrLOCAL char(255),
@CR char(255),
@BLDCHKDT Varchar(50),
@BLDCHTIME Varchar(50),
@hdrline int
SELECT @hdrLOCAL = DDLINE FROM DD40400 WHERE INDXLONG =1
SELECT @CR = DDLINE FROM DD40400 WHERE INDXLONG =2
SELECT @hdrline =1
SELECT
@BLDCHKDT = CONVERT(varchar(20),T756.PAYDATE,105) ,
-- convert(varchar,getdate(),15)
@BLDCHTIME= CONVERT(varchar(20),T756.PAYDATE,105)
FROM STATS.dbo.DD10500 T762
LEFT OUTER JOIN STATS.dbo.DD10400 T756 ON (
T762.INDXLONG = T756.INDXLONG
AND T756.INCLPYMT = 1
WHERE (T756.INCLPYMT = 1)
AND (T762.DDAMTDLR <> 0)
Create TABLE [dbo].[##DD10200B](
[INDXLONG] [int] NOT NULL,
[DDLINE] [varchar](8000) NOT NULL,
[DEX_ROW_ID] [int] IDENTITY(1,1) NOT NULL,
BEGIN
INSERT INTO ##DD10200B (INDXLONG,DDLINE)
VALUES (1,@hdrLOCAL +',' + @CR +','+ @BLDCHKDT +',' + @BLDCHTIME )
END
the only change done is
@BLDCHKDT Varchar(50),
@BLDCHTIME Varchar(50),

Difference between char and varchar, also the difference between varchar2

Hi,
Can anyone explain me the difference between char and varchar, and also the difference between varchar and varchar2...

Varchar2 is variable width character data type, so if you define column with width 20 and insert only one character to tis column only, one character will be stored in database. Char is not variable width so when you define column with width 20 and insert one character to this column it will be right padded with 19 spaces to desired length, so you will store 20 characters in the dattabase (follow the example 1). Varchar data type from Oracle 9i is automaticlly promoted to varchar2 (follow example 2)
Example 1:
SQL> create table tchar(text1 char(10), text2 varchar2(10))
2 /
Table created.
SQL> insert into tchar values('krystian','krystian')
2 /
1 row created.
SQL> select text1, length(text1), text2, length(text2)
2 from tchar
3 /
TEXT1 LENGTH(TEXT1) TEXT2 LENGTH(TEXT2)
krystian 10 krystian 8
Example 2:
create table tvarchar(text varchar(10))
SQL> select table_name,column_name,data_type
2 from user_tab_columns
3 where table_name = 'TVARCHAR'
4 /
TABLE_NAME COLUMN_NAME DATA_TYPE
TVARCHAR TEXT VARCHAR2

Cannot join tables used in the workbook. Join "" not found in the EUL. Atte

Trying to migrate workbooks from one instance to other using discoverer 10.1.2.48.18 i am getting the following error
Unable to open the worksheet requested.
- OracleBI Discoverer was unable to find the worksheet that was requested.
- BIB-10310 An unknown exception occurred.
- Cannot join tables used in the workbook. Join "" not found in the EUL. Attempt to open workbook failed.
but its fine one instance , and in prod i am getting above weird error.
does anybody know how to rectify this.

Note:267476.1 - for those who can't get into metalink but still need to know the answer
Subject: Discoverer Workbook Fails With 'Cannot join tables.Item dependency "" not found in EUL' After EUL Migration, Importing Or Cloning
Doc ID: Note:267476.1 Type: PROBLEM
Last Revision Date: 28-APR-2005 Status: PUBLISHED
The information in this document applies to:
Oracle Discoverer - Version: 4.1 to 10.1
This problem can occur on any platform.
Symptoms
Opening a workbook migrated from one instance to another results in the following errors:
* Unable to load EUL item ...
* Cannot join tables. Item dependency "" not found in EUL.
* Illegal operation... DIS4USR OR DIS5USR caused an invalid page fault in module....
If using the workbook dump utility, you may notice:
* Found in EUL by id *** Name has changed to .. where the new name is really the wrong column
It seems that items are matched by internal item identifiers (IDs) and not by developer keys and names.
Changes
Migrating from one environment to another. For example, you may have performed a database export / import of the EUL schema from DEV to TEST
Cause
The timestamp is the same for both EULs, what can be confirmed by the following SQL statement:
* Discoverer 4:
SQL> select ver_eul_timestamp from eul4_versions;
* Discoverer 9.0.2 , 9.0.4, 10.1 the script is:
SQL> select ver_eul_timestamp from eul5_versions;
If the result of the sql output is the same in both EULs, it means that timestamp of both EULs are the same. Discoverer assumes that the EUL are exactly the same (e.g. this can happedn when one of them is created with export/import of the other EUL schema using database export/import utilities) and this is the reason it tries to match items by identifiers and not by developer keys or names.
Solution
Change the column ver_eul_timestamp in the eul4_versions (4.1) or eul5_versions(9.0.2 - 10.1)tables to be something different in the destination EUL. The format of this column is like year:month:day:seconds:milliseconds
Example:
* Discoverer 4.1:
sql> update EUL4_VERSIONS set VER_EUL_TIMESTAMP =TO_CHAR(SYSDATE, 'YYYYMMDDHH24MISS');
sql> commit;
* Discoverer 9.0.2:
SQL> update EUL5_VERSIONS set VER_EUL_TIMESTAMP = TO_CHAR(SYSDATE, 'YYYYMMDDHH24MISS');
sql> commit;
* Discoverer 9.0.4 -10.1:
Run the script: EUL5_id.sql as the eulowner ID
o For 9.0.4 -- This is found on a PC with the Discoverer Administrator installed in drive:\Oracle Home\discoverer\sql
o For 10.1.0 -- This is found on a PC with the Discoverer Administrator installed in drive:\Oracle Home\discoverer\util

3d3d3d is for red but you have a blackish and color2 is for green but you have it white the rest should be the default colors. it uses the same colors only it changes the vairiant of the color you choice there or normally moc uses colors such as green blue and such which will call your console colors for those respective fields I know moc has /user/share/moc/themes/ that you can edit or make your own for instance copy one and edit it. I think htop uses the same color count which is 8 but with so green will be white when you use urxvt. 8 for normal colors 16 for bright dark and urxvt is 256 which is 16 but can use any of the 256 colors for 16.
just to clarify you have commented out your colors 4-15 and your green and red is weird, and htop aswell as moc is 8 bit. moc theme_yellow_red is default for background so it will use urxvts background
Haahaha, that is simple. And it works!!!
I didn't bother with commenting that because i thought they are not applied. Anyway, thanks man. My urxvt terminal si grateful to you and your thorough explanation. SOLVED!
