FM to check if table (eg BUT000) is not locked

Hi experts,
Any idea which FM can check if the table (eg BUT000) is not being locked before attempting to write record into table?
Thanks

HI
go to SM12 transaction
You can use function ENQUEUE_READ.also you can use the function module GET_LOCKLIST_ADA
hope this helps you

Best way to check if table is empty or not

Hi. I had to check if a table was empty or not, and found different solutions.
One of them called my atention, I readed it was the best way to do it (some 'dual' trick from Steven Feuerstein, they say) :
SELECT 1 FROM DUAL WHERE EXISTS (SELECT 'X' FROM TABLE);
Plan
SELECT STATEMENT ALL_ROWSCost: 4 Cardinality: 1
     3 FILTER
          1 FAST DUAL Cost: 2 Cardinality: 1
          2 INDEX FAST FULL SCAN INDEX (UNIQUE) TABLE.UB_PK Cost: 2 Cardinality: 1
But doing some tests I found this query to have lower cost:
SELECT 1 FROM TABLE WHERE ROWNUM=1;
Plan
SELECT STATEMENT ALL_ROWSCost: 2 Cardinality: 1
     2 COUNT STOPKEY
          1 INDEX FAST FULL SCAN INDEX (UNIQUE) TABLE.UB_PK Cost: 2 Cardinality: 1
So, what about that dual table trick? Should I keep the 'select 1 where rownum=1' as best possible way?
I know it shouldn't matter much, but just wanna know what method works best for checking empty tables :)
Thanks.

As already mentioned, you cannot just base it on cost, as the cost is not specifically a good indicator of the amount of work that will need to be done, it's just an internal figure calculated for that query and isn't really that comparible across different queries.
If you're intending to see if there is data in a table because you want to know whether to query it or not, you are actually better to just try and query the data and capture the NO_DATA_FOUND exception and handle that. In that case it requires no effort or cost up front.

I need to add check whether 21 fields of a internal table are empty or not.

Hello,
I need to add check whether 21 fields of a internal table are empty or not.How can we write a code for the same wand what would be the correct syntax for it.
I tried entering all the fields in the IF loop with AND condition but its giving syntax error.Perhaps this is because the lenght of the IF condition would be more than the allowed one.

Hi,
After the select quiery.
If not itab is initial.
Message 'Table is not empty' type 'I'.
Endif.

Check 2 tables(Table A and Table B) and figure out new columns present in Table A and add these new columns to Table B

How to check 2 tables(Table A and Table B) and figure out new columns present in Table A and add these new columns to Table b.
DDL-
Create table A
( A INT,
B INT,C VARCHAR(2)
Create table B
A INT,
B INT
Any advice on the best approach or method to achieve this.
I understand that I need to check the schema of the columns and then do a match between 2 tables and find new columns and then alter my target table
Mudassar

Can you try this..
CREATE TABLE A ( A INT, B INT, C VARCHAR(2) )
CREATE TABLE B ( A INT, B INT )
Declare @ColumnVar nvarchar(128),@DatatypeVar nvarchar(128)
SELECT @ColumnVar=x.COLUMN_NAME, @DatatypeVar=x.DATA_TYPE
FROM INFORMATION_SCHEMA.COLUMNS AS x
WHERE TABLE_NAME = 'A'
AND NOT EXISTS ( SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'B'
AND COLUMN_NAME = x.COLUMN_NAME )
Declare @SQL VarChar(1000)
SELECT @SQL = 'ALTER TABLE B ADD ' + @ColumnVar + ' '+ @DatatypeVar
Exec (@SQL)
select * from B

I'm not sure what you mean by, 'How to check with table for cursor..?' but I'll offer a comment on your Code Snippet. I think you want to know how to check if a record exists so you know if you need to perform an INSERT or an UPDATE.
Here is a snippet of your code. I'll put my comments in "Comment" style in your code.
-- Insert / Update final profit plan for final_update query using cursor
   FOR rec_final_update_el IN cur_final_update_el
   LOOP
/* There is no need to test for %NOTFOUND since you are using Cursor FOR Loop!
** This construct automatically exits when the last record is processed. */
   EXIT WHEN rec_final_update_el%NOTFOUND;
/* Is this where you would like to know how to Check if the record already exist??
** I asked this because, 'rec_final_update_el.' is not valid syntax. Are you looking for
** an Cursor Attribute or Method you can check here?
** I would suggest a Primary Key or Unique Index on ENT, CENTER, and POST_ACCT
** on the TEMP_FINAL_PLAN table. Then simply perform an INSERT and code an
** Exception to UPDATE when you get a DUP_VAL_ON_INDEX exception. Otherwise,
** you will need to simply run an Implicit or Explicit Cursor to test if the row exists and
** use this return value to determine if you should INSERT or UPDATE. */
   IF rec_final_update_el. THEN

How to check table is creating or not

Hi,
I am creating only one table by running a table creation script(table.sql) which contain 366 partition.but I dont know whether table is creating or not.it is taking long time,sometimes I feel like script is hanging.even before running the script I have even spooled but spool file shows nothing. so how to check table is creating or not from background? can anyone please let me know abt this.this is bit urgent
sql>spool table.log
sql>@table_partition.sql

hi,
I am running the script table_partition which consist of 366 partition and 31 sub partition but the script is hanging.there is no hint in alert log file or anything wat might be the reason is it because of extent size? as extent size for this tablespace where table has to be create is 1mb,wat i suspect is do i need to set for higher value inorder to avoid this?
with regards;

Hi Reddy.......
And another point I want to make u clear............LBWQ is not the Delta Queue.............Delta queue is RSA7...............it comes into play in delta loading.......LBWQ is Extraction Queue.........While delta loading....if we use the Update mode Queued Delta........then any Changes will not directly get updated in the Delta queue.....For the Delta set up.........
1) First u hav to run init with data transfer(After filling the set up table)
2) After that any Changed ........will be recorded in the Extraction Queue(LBWQ)........
3) After a certain number of records get accumulated in LBWQ........We hav to run V3 jobs to bring the data in the Delta queue(RSA7)...
Check this.....

Input Check in Table Control

A table control is created in screen painter and an internal table was used to store particular data in ABAP program.
Information were entered into the table through ABAP program(insert value into internal table). The input check generated by data dictionary do not work due to data not inserted from screen field. How can I solved the problem?
Do I need to manually program the input check using module as following:
FIELD f Module m.
But how can I make the whole row ready for input and with cursor on particular column just like what was done with normal data dictionary input check?
Message class 00 number 058 with text
Entry & & & does not exist in &4 - check your entry
can be used for compute the message.

What are those conditions that will trigger the input check for my situation?
I can only do that for those fields with check table.
Here are what I had done:
<b>Flow Logic</b>
      field EBAN-EKGRP MODULE CHECK_EKGRP. " Purchasing Group
<b>Module code</b>
MODULE CHECK_EKGRP INPUT.
TABLES: T024.
CHECK: EBAN-EKGRP IS NOT INITIAL.
SELECT SINGLE * FROM T024 WHERE EKGRP = EBAN-EKGRP.
IF SY-SUBRC NE 0.
    MESSAGE E058(00) WITH EBAN-EKGRP '' '' 'T024'.
ENDIF.
ENDMODULE.                 " CHECK_EKGRP INPUT
However, this is not applicable for those without check table.
Please help. Points will be awarded for helpful answers.

Status Check on Table of Contents

My status checks work fine for all of my slides, except when I have my "Next" button jump to a slide later down the line. For some reason I'm not getting a checkmark on the TOB for that particular slide.
Also, on that particular slide, the duration will say "1:03" instead of "0.03." 0.03 is what I have allotted according to my slide timeline. So I guess it's taking into account the duration for all of the slides that I'm jumping over. Accessing the slides that I'm jumping over doesn't seem to give me a status check on the slide either.
Has anyone had this problem?
Sorry if this is confusing!

I'll give that a try and see what happens.
Although, my "Next" buttons are set up that way on each slide (they pause at 1.5 seconds) and they seem to be working fine. It's only when I have the "Next" button jump over slides, for example, slide 8 jumps to slide 21 because slides 9-20 are set up as a Glossary, Examples, Resource Information, etc.
I put buttons on each slide so the student can access the Glossary, Examples, and Resource Information at any time during the training. Then on the TOB, I have these slides turned off so the student only accesses them by clicking the button on the slides.
But I'm open to trying anything so I appreciate your suggestion!

Subject: Status Check on Table of Contents
Hi there
I don't believe the check mark will appear unless the slide plays fully. If you have a button on the slide that is pausing at perhaps 1.5 seconds and the total silde time is perhaps 3 seconds, you are essentially skipping over 1.5 seconds of the slide to visit the linked slide. You might try adjusting the pause point so it's at the end of the slide and see if that improves things. It may and it may not. I'm not certain. But it's worth a try.

I want to make the form when it load it check the data in table, if there are no data in table other form will be load.
Sorry for bad English...

Maybe you can do this in form1's Form_Open event:
if dcount("*", "table1") = 0 then
Cancel = True
Docmd.Openform "form2"
end if
