SQVI - Join tables using similar fields (but not same)

Hi folks!
I would like to know if there is a way to do a join between two tables thru fields that are similar but not exactly the same. For example, I need to join tables EKKO and CDHDR, where the PO numbers do exist in both the tables (EKKO-EBELN and CDHDR-OBJECTID), but the fields are different. Is it possible to achieve such kind of a join?
Appreciate your help.
Regards,
Anwar.

unfortunately it is not enough... You have to select separately from the two tables and merge the data somehow in the program.

Joining tables with "similar" field values

I have run into a situation where I want to join two tables on a field called U_LotusBox.    In my main table the the feild can contain values like 1 or 2 or 3 or 1,2,3,4. That's 1 comma 2 comma 3 comma 4. My field in the second tables contains only single digit values, like 1 ,2, 3 up to 5.
When the two fields are identical I am able to retrieve data. But if my field in the main contains a value of 1,2,3 and my secondary table field value is 2 I get no data returned because the two fields are not identical.
Is it possible to have a join that is "fuzzy" meaning that if the main table field values contains the value of the secondary field value, 2 in my example would it be possible to return data?
Any thoughts would be appreciated.

Ralph,
Here in high-level details is an SQL example of creating two tables (test1 and test2) with one column in each table (col_a and col_b, respectively) to show how a join on a substring of one column can be tied to a column of another table:
create table test1 (col_a char(5))
create table test2 (col_b char(1))
insert into test1 values ('1')
insert into test1 values ('1,2,3')
insert into test2 values ('1')
insert into test2 values ('2')
select col_a,test2_tbl1.col_b
from test1 inner join test2 as test2_tbl1 on col_a=test2_tbl1.col_b or
substring(col_a,1,1)=test2_tbl1.col_b or
substring(col_a,3,1)=test2_tbl1.col_b or
substring(col_a,5,1)=test2_tbl1.col_b
col_a     col_b

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

Connection ... able to connect using sql developer, but not sqlplus or toad too

Hi folks, having this issue, with only one of my so many databases, what might be the reason and how to fix/correct this, please assist.
Able to connect using sql developer, but not sqlplus or toad too; sqlplus error: ORA-12154: TNS:could not resolve the connect identifier specified
thanks in advance.

SQLDEVELOPER works since it use JDBC Thin & does not use tnsnames.ora
ORA-12154 ALWAYS only occurs on SQL Client & no SQL*Net packets ever leave client system
ORA-12154 [B]NEVER[/B] involves the listener, the database itself or anything on the DB Server.
ORA-12154 occurs when client requests a connection to some DB server system using some connection string.
TNS-03505 is thrown by tnsping & is same error as ORA-12154 thrown by sqlplus or others.
The lookup operation fails because the name provided can [B]NOT[/B] be resolved to any remote DB.
The analogous operation would be when you wanted to call somebody, but could not find their name in any phonebook.
The most frequent cause for the ORA-12154 error is when the connection alias can not be found in tnsnames.ora.
The lookup operation of the alias can be impacted by the contents of the sqlnet.ora file; specifically DOMAIN entry.

Hi Sai,
Thanks for your response, I am using PFAL transaction to transfer the employees from ECC to CRM. and I am using only one emplyee for execution, is there any other transactions to replicate employees.
In ECC, after executing the PFAL transaction, getting successful transfer of IDoc message with green light.
In CRM in WE02, it is showing yellow light for the same IDocs.
but even with yellow light (Warning) some employees are successfully converting into BPs, but some employees are not converting.
I could not trace the problem that, why it is happening. IDocs are reaching to CRM system, but some idocs are not converting into BP where as some IDocs are converting into BPs successfully.
Please help me to resolve this issue.
Your suggestions will be highly appreciated.

SQVI Join Tables

Hello everyone,
I'm trying to use SQVI to join table AGR_TCODES and TSTC and link TCODE. However, (I'm guessing) that since the Long Text on TCODE in one table is different than the other, I can not create a link between the two.
Any thoughts?
Thanks,
Tom

Hi Thomas,
I wanted to do the same thing, and like you I can't get it to work.
Like with you the table AGR_TCDTXT isn't filled. So this is of no use.
Then I tried using this empty table as a sort of dummy table, linking TSTCT and AGR_TCODES, using "left outer joins". The joins are accepted in SAP, but as I expected it didn't work.
Have you found the solution yet?
Best,

DROP TABLE works through SSMS but not via T-SQL Query

Hello All,
I am trying to drop a number of tables (1,000+) in a particular database by scripting the actions in T-SQL. When I run the query I get error 3701 on every table which points to a permissions issue. However, I am able to delete tables one by one using
the tree-view in the SSMS Object Explorer.
1. I have tried starting query sessions with both the DBO of the database and the SA account to no avail. (Both had the sysadmin role when I tried.)
2. Both the DBO account and the SA account are able to drop tables using SSMS Object Explorer.
Do I need a specific GRANT of permissions to use T-SQL versus SSMS or am I missing something even more fundamental?
TIA, Simon

3701 = ...does not exist or you don't have permission.
Most of the time it means the former. So there are probably some problems in your DROP TABLE statements. Since there is a whole lot about Navision in the script, I decline from trying to figure out what. But I encourage you to study the PRINT statements.
I think that it would be a good idea to include the schema name, in cases these tables are not in dbo after all.
Note: rather than writing:
   SET @STATEMENT = 'DROP ' + @OBJECT_TYPE + ' [' + @OBJECT_NAME_BARE + ']';
write:
   SET @STATEMENT = 'DROP ' + @OBJECT_TYPE + quotename(@OBJECT_NAME_BARE)
Somewhat briefer. And it works also when the object name includes a right bracket.
sp_sqlexec is undocumented, use sp_executesql instead.

Mandatory for Visable field but not for hidden field

Hi All,
I have a couple of radio buttons (Yes and No) when the user selects Yes they are then prompted for the date this happend.
How can i make the Date field mandatory if they select yes but not if they select no. I have tried making the date field mandatory but it throughs the obvious error if it is hidden.

Hi George, thanks for your reply.
The way i hide and show the date box at the moment is by using the Show/Hide field action under the properties of the radio buttons.
Thx

Bad exec plan when joining tables using primary keys together w/ Contains

Hello all...this is something that confuzzles me....
When joining 2 tables, the exec plan shows that the domain index is first accessed, before checking if there is a record in the other table using a highly selective index.
create table users
(userid varchar2(20),
name varchar2(100),
resume clob
create table seeker
(seekerid varchar2(20),
userid varchar2(20),
jobid varchar2(20)
create index user_idx on users(userid)
create index job_resume_index on users(resume)
indextype is ctxsys.context
create unique index seeker_unik on seeker(seekerid)
create index seeker_index on seeker(jobid,userid)
then sample records where inserted, then the text index was sync'ed.
Query and Execution Plan:
select u.userid, u.name
from users u, seeker s
where s.jobid = 'HJOBP000000000218627'
and u.userid = s.userid
and contains(resume,'texas') > 1
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=3 Card=1 Bytes=72)
1 0 NESTED LOOPS (Cost=3 Card=1 Bytes=72)
2 1 TABLE ACCESS (BY INDEX ROWID) OF 'USERS' (Cost=2 Card=1
Bytes=30)
3 2 DOMAIN INDEX OF 'JOB_RESUME_INDEX' (Cost=0)
4 1 INDEX (RANGE SCAN) OF 'SEEKER_INDEX' (NON-UNIQUE) (Cost=
1 Card=1 Bytes=42)
The problem with execution plan is if the domain index returns huge number of records i.e. 40k rows, then it has to check each userid with the SEEKER table, and returns only 10 rows. I can add a hint to specify the use of the user_idx instead of the domain index to improve performance.
My question is how does the database determine when to use the domain index or to use other highly selective index with out the aid of a HINT. The trace file shows the use of "CTXSYS"."TEXTOPTSTATS".ODCIStatsIndexCost and "CTXSYS"."TEXTOPTSTATS".ODCIStatsFunctionCost. Are these used to compute and compare the cost of each index and decide on what index to used? If so, why does it return a lower cost for domain index when the btree index is more efficient? I have all statistics gathered for all tables and indexes (inc dr$ tables and its indexes)
Thanks,
jojo

Hi,
What I'm pasting here is actually from Ch9 of Expert PL/SQL. It shows what happens during a select with CONTAINS. It does not include a join with another table, or an additional column in the where clause. Hope it helps.
================================================
By default, the Extensible Query Optimizer is enabled. When enabled, the Extensible Query Optimizer can determine the I/O and CPU cost associated with the CONTAINS predicate, find the cost of each call to the CONTAINS() function, and determine the selectivity of the CONTAINS predicate.
To see this in action I ran the basic select earlier. Examining the SQL trace shows the steps.
Step 1 - Determine the I/O and CPU cost of the CONTAINS() function:
--Available online as part of contains_trace.doc
"CTXSYS"."TEXTOPTSTATS".ODCIStatsFunctionCost(
sys.ODCIFuncInfo('CTXSYS',
'CTX_CONTAINS',
'TEXTCONTAINS',
2),
cost,
sys.ODCIARGDESCLIST(
sys.ODCIARGDESC(
2, 'DOCUMENT_REPOSITORY', 'PLSQL',
'"DOCUMENT"', NULL, NULL, NULL),
sys.ODCIARGDESC(3, NULL, NULL, NULL, NULL, NULL, NULL)),
NULL,
'constitution',
sys.ODCIENV(0,0,0,1));
Step 2 Determine the selectivity of the CONTAINS predicate
-- Available online as part of contains_trace.doc
"CTXSYS"."TEXTOPTSTATS".ODCIStatsSelectivity(
sys.ODCIPREDINFO('CTXSYS',
'CTX_CONTAINS',
'TEXTCONTAINS',
32),
sel,
sys.ODCIARGDESCLIST(
sys.ODCIARGDESC(3, NULL, NULL, NULL, NULL, NULL, NULL),
sys.ODCIARGDESC(5, NULL, NULL, NULL, NULL, NULL, NULL),
sys.ODCIARGDESC(2, 'DOCUMENT_REPOSITORY', 'PLSQL',
"DOCUMENT"', NULL, NULL, NULL),
sys.ODCIARGDESC(3, NULL, NULL, NULL, NULL, NULL, NULL)),
0,
NULL,
NULL,
'constitution',
sys.ODCIENV(0,0,0,1));
Step 3: Determine the I/O and CPU cost of the CONTAINS predicate
-- Available online as part of contains_trace.doc
"CTXSYS"."TEXTOPTSTATS".ODCIStatsIndexCost(
sys.ODCIINDEXINFO('PLSQL',
'EXPERT_IDX',
sys.ODCICOLINFOLIST(
sys.ODCICOLINFO('PLSQL', 'DOCUMENT_REPOSITORY',
'"DOCUMENT"', 'BFILE', NULL, NULL)),
NULL,
0,
0),
50.00000000,
cost,
sys.ODCIQUERYINFO(
2,
sys.ODCIOBJECTLIST(sys.ODCIOBJECT('SCORE', 'CTXSYS'))),
sys.ODCIPREDINFO('CTXSYS', 'CONTAINS', NULL, 0),
sys.ODCIARGDESCLIST(
sys.ODCIARGDESC(3, NULL, NULL, NULL, NULL, NULL, NULL),
sys.ODCIARGDESC(5, NULL, NULL, NULL, NULL, NULL, NULL),
sys.ODCIARGDESC(2, 'DOCUMENT_REPOSITORY', 'PLSQL',
'"DOCUMENT"', NULL, NULL, NULL),
sys.ODCIARGDESC(3, NULL, NULL, NULL, NULL, NULL, NULL)),
1,
NULL,
'constitution',
sys.ODCIENV(0,0,0,1));
Note: The 50.00000000 in this last call is the selectivity retrieved from step 2.
Only after these three steps complete does the query actually get executed:
-- Available online as part of contains_trace.doc
SELECT score(1), title
FROM document_repository
WHERE CONTAINS(document, 'constitution', 1) > 0
ORDER BY 1 DESC;
This is not the end of the processing though. To retrieve the records, the $I table (the index data table) is queried as follows:
-- Available online as part of contains_trace.doc
SELECT /*+ INDEX(i) */ TOKEN_FIRST,TOKEN_LAST,TOKEN_COUNT,ROWID
FROM "PLSQL"."DR$EXPERT_IDX$I" i
WHERE TOKEN_TEXT = 'CONSTITUTION'
AND TOKEN_TYPE = 0
ORDER BY TOKEN_TEXT, TOKEN_TYPE, TOKEN_FIRST;
Note: The search term is UPPERCASE when querying against the DR$EXPERT_IDX$I table because all of the tokens are stored in uppercase by default. The original SELECT was in lowercase. This automatic conversion to uppercase allows the Text index to provide case-insensitive searching.
This query returns the following result:
TOKEN_FIRST TOKEN_LAST TOKEN_COUNT ROWID
1 2 2 AAAN54AAEAAAOvEAAo
Finally, the $R table (the rowid table) is queried.
-- Available online as part of contains_trace.doc
SELECT data
FROM "PLSQL"."DR$EXPERT_IDX$R"
WHERE row_no = 0;
Only now do I see the results of my query:
SCORE(1) TITLE
55 United States Constitution
8 Bill of Rights
Keep in mind that modifications to the query, such as the addition of other columns in the where clause or the addition of operators, will result in a different trace.
