Format a field using update statement

Hello,
What I am trying to do is update a field by using values from two fields from the same table. When I entered the following query, I got the error message ORA-00903: invalid table name. Any suggestions?
Update [Select Reg1.State _Field, Reg1.Route, Reg1.County
From Reg1
Where Reg1.State _Field Is Null]
Set Reg1.State_Field=
Reg1.Route &Reg1.County;

[Select Reg1.State
Are you using SQL server or Oracle?

Updating data without using update statement

Hi,
A quick question...
Can any table data could be updated without using update statement from backend.
Just wanted to make sure.
Thanks in advance.

Hi,
What is your definition of Update?
Since your question is vague and you dont explain what exactly you mean.
here are my thoughts
1) A record can be deleted and isnerted with new values.Where the nes values have only few columns changed from previous ones.
2) I use pl/sql developer.If i need to update i can write select.. for update.Change the values (as in notepad)Commit.
This is infact a update but with nice UI
3) even your application can update data in your tables, if you code it and give correct privileges to the userRegards,

How to use Update Statement in ODI Procedure

Hi,
How can I use an update statement inside an ODI procedure.
Thanks

Hi,
You do not need the BEGIN and END. ODI procedures are free text, so you can simply write your update statement, as you would in toad/sql developer etc etc. Just make sure you set the Technology and the logical schema. It is how ever best practice to also use the API:
<%=odiRef.getSchemaName("YOUR_LOGICAL_SCHEMA_NAME", "D")%>. to prefix tables. This way, you select data from different schema's in the same instance (as long a your user has the correct privs).

How to lock a row before update using UPDATE statement ?

I want to lock a row before updating using the UPDATE statement! is there any "reserved word" that I can append to an update statement so, that the row get locked!, also, will the lock gets released automatically once the update is done or do I have to explicitly release the lock?
how can I do this ?
any help is greatly appreciated.
Thanks,
Srini.

For detail information, see http://otn.oracle.com/doc/server.815/a67779/ch4l.htm#10900
The lock will be released by "commit".
FOR UPDATE Examples
The following statement locks rows in the EMP table with clerks located in New York and locks rows in the DEPT table with departments in New York that have clerks:
SELECT empno, sal, comm
FROM emp, dept
WHERE job = 'CLERK'
AND emp.deptno = dept.deptno
AND loc = 'NEW YORK'
FOR UPDATE;
The following statement locks only those rows in the EMP table with clerks located in New York. No rows are locked in the DEPT table:
SELECT empno, sal, comm
FROM emp, dept
WHERE job = 'CLERK'
AND emp.deptno = dept.deptno
AND loc = 'NEW YORK'
FOR UPDATE OF emp.sal;

JDBC and using update statements

I have a program that connects to a microsoft access DB using JDBC-ODBC Bridge, but i dnt know how to write a correct update statement. I use servlets & it should call a function that retrieves a specific value, adds 1 to that integer value and updates the DB,but it didn't work. i also need to know how to delete all records in a DB.
Thanks in advance

Copy records of one table into another using Update statement

Supposing I have 2 tables test and test1.
Test has columns col1 and col2. and test1 has only one table col1.
select * from test returns:
COL1 COL2
a
b
c
d
e
select * from test1 returns
COL1
p
q
r
s
t
Suppose i want to copy values of test1.col1 to test.col2 so tht final result of
select * from test should be
COL1 COL2
a p
b q
c r
d s
e t
I found a query in the OCP introduction book:
update test set col2=(select col1 from test11)
this works fine only when we have a single record in test1 table but fails otherwise.
how can this be achieved using the update statement ?

SQL> desc test

This will work only if you have the same number of lines in COL1 in both tables. If you have different number of lines, then you need to code more at join (outer, inner).
But for complicated cases, please post sample data.
Michael
PS: And supossing that the values are distinct in TEST table. Else update will fail, because more rows will be retrived.
If more values in TEST table in COL1, then you need to assign a row number on TEST also, and in WHERE of query you need to place one more join condition:
something like:
8* ) z where z.col1 = test.col1
and z.rn = test.rn)
SQL> /
But as i said, get more specifications.

Assigning values to 2 fields using sql statement

db11g , apex 4.0 and firefox 24 ,
hi all ,
i am trying to follow this tutorial to assign values to 2 items on a page using sql statement ,
and i am using the same sql statement the tutorial uses
select d.loc location, count(e.empno) num_employees from dept d, emp e where d.deptno = e.deptno(+) and d.deptno = :P3_DEPTNO group by d.loc -- btw , what does the "+" sign mean?
after the e.deptno in the where condition .
but i am facing this error
1 error has occurred
Wrong number of columns selected in the SQL query. See Help of attribute for details.
and it does not work with two columns in the select statement under any conditions , i tried to remove the group function and the group clause ,
it does not work unless i use only one column in the select statement ??
thanks

Pars
And how exactly is this rewrite of the sql statement resolving the OP's issue.
You are still using more than 1 column which will still result in the error message:
Wrong number of columns selected in the SQL query.
As mentioned in my earlier post APEX 4.0 (the version the OP is using) does not handle a sql statement with multiple columns for the dynamic action Set Value.
Which means the fastest and simplest solution is splitting up the dynamic action in multiple Set Value actions.
Using this plugin or upgrade to a newer apex version would also be a possibility.

* Commit work on table using UPDATE statement.*

HI,
   This is Anil . I have problem regarding Commit work and Wait up to 2 seconds.
I am using Commit work on one Update table statement but it is not working . While doing debugging it is working
(means it is updating Table.) but while running the transaction directly it is not updating the table.
Check the statements :
Commit work.
Some Select stmt on <table>.
IF <condition.>
Update <table > statement.
if sy-subrc EQ 0.
    Commit work . ( This is not working while running transaction mean it is not updating table. While debuggint it it updating table.)
     wait up to 2 seconds.
endif.
endif.
Will that above Commit work causing any problem or what is the reason it is not updating table.
Please give some suggestion in this case.
Regards,
Anilreddy.

Hi
the below code with commit work is working finr for me.
only thing i suggest is to check sy-subrc value.
commit work.
update spfli set test = '1234' where carrid = 'AA'.
if sy-subrc eq 0.
commit work.
wait up to 2 seconds.
endif.
write: / sy-subrc.

Update statement in Internal Table

Plz tell me the syntax and e.g. of update statement in Internal Table program
Moderator message: Welcome to SCN, please research yourself before asking basic questions.
Edited by: Thomas Zloch on Feb 25, 2010 12:47 PM

Hi,
Use UPDATE statement , check below description from SAP help.
UPDATE dbtab FROM TABLE itab. or UPDATE (dbtabname) FROM TABLE itab.
Effect
Mass update of several lines in a database table.Here, the primary key for identifying the lines tobe updated and the values to be changed are taken from the lines of theinternal table itab.
The system field SY-DBCNT contains the number of updated lines,i.e. the number of lines in the internal table itab which havekey values corresponding to lines in the database table.

Problem regarding Update-Statement on se11 table

Hello I tried to update a dataset in a se11 table using UPDATE Statement.
It doesn't work and I get a sy-subrc = 4.
That is my code:
TABLES ZTDM_SAPOUTPUT.
* Arbeitsbereich definieren
DATA:
wa_ZTDM_SAPOUTPUT LIKE ZTDM_SAPOUTPUT.
wa_ZTDM_SAPOUTPUT-PK = '1'.
wa_ZTDM_SAPOUTPUT-FNCODE = '3'.
wa_ZTDM_SAPOUTPUT-MATNR = '3'.
wa_ZTDM_SAPOUTPUT-MAKTX = '3'.
wa_ZTDM_SAPOUTPUT-ZEINR = '3'.
wa_ZTDM_SAPOUTPUT-MATKL = '3'.
wa_ZTDM_SAPOUTPUT-STATE = '1'.
UPDATE ZTDM_SAPOUTPUT FROM wa_ZTDM_SAPOUTPUT.
Write: 'UPDATE returned' , sy-subrc.
SKIP.
The given Dataset having PK=1 doesn't get updated.
Maybe my understanding is wrong:
Is it correct that the updated dataset ist defined by the primary key in this workingarea?
My Primary Key is PK.
Can you see the error?

UPDATE dbtab FROM wa. or
UPDATE (dbtabname) FROM wa.
Changes one single line in a database table, using a primary key to identify the line and taking the values to be changed from the specified work area, wa. The data is read out of wa from left to right, matching the line structure of the database table dbtab. The structure of wa remains unchanged. This means that wa must be at least as wide (see DATA) as the line structure of dbtab, and have the same alignment. Otherwise, a runtime error occurs.
If either the database table, dbtab, or the work area, wa, contain Strings, wa must be compatible with the line structure of dbtab.
Example
Changing the telephone number of the customer with customer number '12400177' in the current client:
DATA wa TYPE scustom.
SELECT SINGLE * FROM scustom INTO wa
WHERE id = '12400177'.
wa-telephone = '06201/44889'.
UPDATE scustom FROM wa.
When the command has been executed, the system field SY-DBCNT contains the number of updated lines (0 or 1).
Examples
Update discount for the customer with the customer number '00017777' to 3 percent (in the current client):
DATA: wa TYPE scustom.
SELECT SINGLE * FROM scustom INTO wa
WHERE id = '00017777'.
wa-discount = '003'.
UPDATE scustom FROM wa.
The Return Code is set as follows:
SY-SUBRC = 0:
The specified line has been updated.
SY-SUBRC = 4:
The system could not update any line in the table, since there is no line with the specified primary key.

Dynamic Update Statement in Native SQL

Hi Experts,
I want to dynamically pass the field in Update statement in Native SQL. For eg.
data: str1 type string.
str1 = 'MARKETS'.
EXEC SQL.
      UPDATE PRDT.TBVEHDS4 SET (str1) = :'U'
      WHERE VEH_NO       = :'K1WK-54520'
      AND    SEGMENT_NO   = :'01'
ENDEXEC.
But this is not taking (str1) as MARKETS field to update as U , its taking STR1 itself, Giving native SQL exception as Invalid Token as we are using DB2 as external DB system.
I checked with field-symbols also, but nothing helped.
Please help, thanks in Advance.
Regards,
Abhishek

Hi,
Check this demo program in SE38 ADBC_DEMO, take as example to construct your own dynamic native sql

Change AUSP-ATWRT without Update statement

Hello,
I am looking for any kind of FM / BAPI/standard way to update AUSP-ATWRT field without using UPDATE statment. I can not use UPDATE statement in my code.
Any help is appriciated!
Thanks in advance

Hi,
So... where and how have you looked thus far..? I'm not trying to be difficult or snide here, but if I, who didn't know of the existance of AUSP some 12 minutes ago did find what I believe to be the correct BAPI by:
1) looking at the table description to figure out what the table contains, and
2) doing one search on SCN...
you will too, I believe...
cheers

Update statement is not working(urgent)

Hi,
when i use below code it gives me dump when reocrds arem ore.
loop at itab.
update de1000 SET vrprs = itab-rfwrt
where kaufn = itab-vbelv
and mtpos IN soption and perio = perio and VRPRS <> 0.
endloop.
the structure of itab and de11000 is not same.
please suggest me alternative.
thanks
jack

I believe you can not use update statement with in loop & endloop. it will dump.
Here is further info. Create another internal table with
the same structure of de1000 and update the table with required values. finally use the following state
update de1000 from table t_de1000(internal table)(check syntex)

UPDATE statement in Receiver JDBC adapter

Hi all,
I would like to use UPDATE statement in my receiver JDBC adapter and would like to know how this UPDATE statement works in following case.
1) If i have 10 records to be updated in database, whether Commit happens at the end of all 10 records updation OR it will be for every record update?
Regards

Hi,
Then let me construct my query this way...
i have 10 records that needs to be updated to database, say For Ex: 7 records are updated successfully and 8th record has issue in updating the table.
In this case i would like to ROLLBACK entire 10 records with out committing any thing.
So if i use your 2nd option, it should perform as i expected right?
Regards

Doubt about UPDATE STAT COLUMN

Hi,
I have a doubt of when to execute update stat:
i create this SQL to generate an SQL script to generate update stat for all my tables:
select 'UPDATE STAT ' || schemaname || '.' || tablename || ' ESTIMATE SAMPLE 20 PERCENT' from tables where schemaname = 'DBUSER' and not tablename like 'JDBC%' AND type = 'TABLE'
and created this SQL to generate an SQL script for update stat for all columns.
select 'UPDATE STAT COLUMN(*) FOR ' || schemaname || '.' || tablename || ' ESTIMATE SAMPLE 20 PERCENT' from tables where schemaname = 'DBUSER' and not tablename like 'JDBC%' AND type = 'TABLE'
my doubt is i really need run that second script? or the UPDATE STAT for table dont UPDATE STAT for all columns?
thanks for any insight
Clóvis

> my doubt is i really need run that second script? or the UPDATE STAT for table dont UPDATE STAT for all columns?
Hi Clovis,
hmm... good question.
There are a few things to know about the UPDATE STAT command here.
1) It will always generate statistics for key or indexed columns.
2) The optimizer won't be able to generate a better plan when there are column statistics for non-indexed columns present.
3) The command will also collect column statistics for all columns that already have statistics.
The direct effect of 3) is that by running your second command just once - all column statistics will always be collected.
Since you can easily change the default sample size for your tables via
ALTER TABLE SAMPLE SIZE 20 PERCENT
I would say: drop your script and just use
UPDATE STAT DBUSER.* ESTIMATE
This single command would lead to the same statistics as your script does.
And if you really, really want to leave out the JDBC tables - then just set their default sample size to 0 and they will be ignored by the UPDATE STAT command.
regards,
Lars
