How to tackle this problem of handling the decode ....while we have group by also.
This is bit urgent
Thanks for your help

Hi,
Thanks for the quick reply.
Here is the code...i have included the decode for the customer carrier code...

Can anyone help me in this to avoid the problem.

If I want to order by dateAdded to I have to include it in the select statement like

If I do this:
<cfquery name="chart" datasource="#datasource#">
select behaviourID,score, dateAdded2 = convert(varchar,
dateAdded , 101)
from staff_charts_data
where userID =
<cfqueryparam value="#arguments.userID#"
cfsqltype="cf_sql_integer"> AND
NOT score = 5
</cfquery>
If I want to order by dateAdded to I have to include it in
the select statement like so:
<cfquery name="chart" datasource="#datasource#">
select behaviourID,score, dateAdded2 = convert(varchar,
dateAdded , 101),dateAdded
from staff_charts_data
where userID =
<cfqueryparam value="#arguments.userID#"
cfsqltype="cf_sql_integer"> AND
NOT score = 5
</cfquery>

you should be able to order by dateAdded without it being in
the select clause. The only time the order by field has to be in
the select clause is when your query has an aggregate and group by
clause, like this:
select field1, field2, max(field3) as youralias
from sometables
where whatever
group by field1, field2
order by ???
You can only order field1, field2, max(field3) or youralias.
You can't order by field4.

How can I call a Page Process from the Select statement for Report Page

I'm able to call a javascript using the below:
img src="#IMAGE_PREFIX#add2.gif" border="0" alt="Icon 4" onClick="javascript:add_connect1('||CPORT.ID||')"
But Now,
I'd like to accomplish (2) New things:
1. instead of using,....... onClick="javascript:add_connect1,
I'd like to call a Page Process, onClick=
2. I'd like to be able to call two different processes onClick.
a. onClick="javascript:passBack('||ID||')"
b. onClick= <Please see my question #1 above>
Can someone please help me with the syntax for this,
If indeed it can even be done?
Thanks- Gary

Greg.
It seems that my situation is the one you describe in you second paragraph, where you mention:
you could then add the ID column value as a parameter to the javascript functionBut,
I do not know how to reference the variable in my javascript nor how to use it in my on-demand process.
If you can hellp me past this last little bump, then I think I will be able to use these skills in Sooo many different areas of my design.
Here's what I've got so far:
A. In the select statement I identify the javascript as:
onClick="javascript:connect_port('<font color=blue>''||ID||''</font>')";
B. In my javascript I have this:
<script language="JavaScript" type="text/javascript">
function connect_port(ID)
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=CONNECT_PORT',0);
gReturn = get.get();
get = null;
</script>
C. In my on demand function I have this:
BEGIN
INSERT INTO CCONNECTIONS_B
BLDG_ID,CLST_ID,PORT_ID,STRAND_ID
) VALUES
:P2004_BLDG_ID,:P2004_CLST_ID,:P2004_PORT_ID,:P2004_STRAND_ID1
END;
You can see that I dont know how to use the value for 'ID' in either the javascript or the On-Process function.
If you can help me out with this one, Then I can imitate it for the rest.

Case sensitive statement in the select-statement

Hi All,
i have a table in the abap-dictionary filled with names...when i try to select them with the select-statement with condition:
table-name_column like 'some_name'
I have encountered some problems...the inquiry is case-sensitive. What i want to do is to read the value from the abap-dictionary table uppercase or lowercase and compare it with the needed value also translated in uppercase or lowercase.
The only idea i have is to select all values of the dictionary table into an internal table and to translate the values there in uppercase or lowercase and then to loop trough it. But this approach would cost a lot of performance.
Do someone has an other proposal?

check...
Select statement
It would be difficult , because it is based on how data is stored in the data base , now consider the scenario of the system i am using , we can material description as 'test' or 'TEST' , 'Test' .
If in your system there are only stored in either caps or small the you can perform the select twice .
But i myself dont find it to be such a good solution , but you can give it a try
There is one more solution specific to material description ,and that is in the table MAKT there is a field MAKTG , which stored the description in uppercase , so for this you can first convert the description to uppercase and then perform select on this field

How to test the select statement.

Hi All,
How to test the select statement.
Is there any Oracle sqlplus or toad kind of tool to test the query.
thanks
siva

Use SQL Trace (ST05) and choose 'Explain one SQL Request'. Enter your SQL command as it should be executed in the underlying database. e.g. if the db is Oracle, the statement should be entered as:
SELECT matnr,werks,lvorm,dispo
FROM marc
WHERE mandt = :a AND
matnr = :b AND
werks = :c
In the above :a, :b and :c are place holders for the actual comparison values. You dont have to enter those values. When you choose 'Explain' button, you will find the 'Execution Plan'. The important parameter which denotes the efficiency of the SQL statement is the 'Cost'. The cost should be as low as possible. The table access should be through INDEX UNIQUE SCAN. If you get a FULL TABLE SCAN and higher cost, you need to fine-tune your statement by modifying the where clause.
If you dont know Oracle SQL statements, execute the program in trace mode and go to the trace and you will find the underlying SQL statements issued to the database.

Restricting records in the select statement

Hi,
I have one requirement where in i need to restrict my select statement to get only 250 records in the output table.
Here are the select statements i am using....
    SELECT a~ebeln
                 a~lifnr
                 a~ekgrp
                 b~werks
                 b~matnr
           FROM ekko AS a INNER JOIN ekpo AS b
           ON aebeln = bebeln
           INTO TABLE i_ekko
           WHERE a~ebeln IN r_ebeln AND
                        a~lifnr IN r_lifnr AND
                        a~ekgrp IN r_ekgrp AND
                        b~werks IN r_ewerk AND
                        b~matnr IN r_matnr AND
                        a~bstyp = 'F'.
            IF NOT i_ekko[] IS INITIAL.
Select Vendor name
           SELECT lifnr
                        name1
                  FROM lfa1
                  INTO TABLE i_lfa1
                  FOR ALL ENTRIES IN i_ekko
                  WHERE lifnr = i_ekko-lifnr.
Here if i restrict the first select statement to get only 250 records then i am not getting the desired record in the second select statement.
Could anyone let me know how to write the select statement.
Regards,
Ramesh

restric the first select using up to 250.
sort the i_ekko by vendor name.
ex: sort i_ekko by lifnr.
use second select statement here.

Database adapter and column aliases in the select statement (10.1.3.1)

Hi,
Is it possible to use column aliases in the select statement for a database adapter to return an xml element name which is different to the column in the queried table?
I have tried using
SELECT EMPLOYEE_ID, FIRST_NAME AS MYNAME, LAST_NAME, SALARY, DEPARTMENT_ID, PHONE_NUMBER, EMAIL, HIRE_DATE FROM HR.EMPLOYEES WHERE (DEPARTMENT_ID = #DEPT_ID)
but I get the following XML fragment returned
<Employees>
<employeeId>100</employeeId>
<firstName xsi:nil="true" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/>
<lastName>King</lastName>
<salary>24000</salary>
Any pointers appreciated.
Joel.

That is really interesting.
When I use the "custom sql" option in the DB adapter wizard, it used the aliases just fine in the return schema.

How to find the select statement has written all selected values into text

Hi,
I am using form6i. i am selecting a set of values from database tables based upon some user parameters and writing into the text file using Text_io.put_line . In this case how we can make sure that the text fille contains all the data what we are selected from selected statement. somebody told that there might be chances of aborting of data while writing into the text file. is there any way to fild out the selected statements has written all the selected fields and corresponding output into the .txt file.
Please suggest me.

somebody told that there might be chances of aborting of data while writing into the text fileWhat kind of "chance" does that somebody refer to?
If you want to verify if the number of records (lines) in the file matches the number of records from the cursor, you could re-open the written file in read-mode and count the number of lines by reading one by one, then compare the number of lines with the number of records from the cursor.

Break the SELECT statement.

Hi,
My requirement is to break the Select statement and get the fields in where clause in one internal table.
For eg: Select VBELN
                      POSNR
                      MATNR from VBAP into wa_vbap where VBELN = '0000000001'
                                                                          and   POSNR = '000010'.
Here i need to put fields VBELN, POSNR, MATNR in one internal table, table name VBAP in second internal table and where clause fields VBELN, POSNR in third internal table.
Please let me know if anyone has any solution for this.
Thanks in advance.
Sunanda.

TABLES: VBAP.

APPEND ITAB3.
LOOP AT ITAB3.
    SELECT VBELN POSNR MATNR FROM VBAP INTO TABLE ITAB1 WHERE VBELN EQ
ITAB3-VBELN AND POSNR EQ ITAB3-POSNR.
      WRITE ITAB1-VBELN.
ENDLOOP.
WRITE: 'SUBRC=', SY-SUBRC.
I am unable to find out how to satisfy your second internal table requirement.
Hope this helps

Substring in the select statement

Hi,
Have a table with 5 columns in it...
Table A
col1
col2
col3
col4
col5
Want to retrieve some columns from that table using the select query, in which substring will be used to extract a part of string from each value contained in the col3 on executing select statement.
How to use the substring in the select statement to perform the above?
Regards

What's wrong with <tt>SUBSTR(col3,4,2)</tt> etc? What do the other columns have to do with it?

Calling an SP takes over 200% more time over the select statement

As part of my POC converting a SQL Server application over to SAP HANA, I'm find that CALL is taking over 200% more time than calling the SELECT statement directly. The result is that the application that uses ODBC against HANA with CALL statements is taking much more time than SQL Server. I'm finding this for all stored procedure calls in the application. Here is an example:
CREATE PROCEDURE dbo.usp_GetOrdersByCustomerID
(IN C_ID bigint)
LANGUAGE SQLSCRIPT DEFAULT SCHEMA "DBO" READS SQL DATA
AS BEGIN
SELECT TOP 20
   C_F_NAME,
            C_L_NAME,
            C_EMAIL,
            O_ID,
            O_TOTAL,
            O_DTS,
            O_FM_DTS
FROM    dbo.Customer JOIN dbo.Orders ON C_ID = O_C_ID
WHERE   C_ID = :C_ID
    ORDER   BY O_ID DESC;
END;
When using the following CALL statement in SAP HANA Studio
CALL dbo.usp_GetOrdersByCustomerID(3429);
I get execution times that look like this:
Statement 'CALL dbo.usp_GetOrdersByCustomerID(3429)'
successfully executed in 9 ms 663 µs (server processing time: 8 ms 115 µs)
Fetched 5 row(s) in 0 ms 69 µs (server processing time: 0 ms 0 µs)
Statement 'CALL dbo.usp_GetOrdersByCustomerID(3429)'
successfully executed in 11 ms 851 µs (server processing time: 8 ms 238 µs)
Fetched 5 row(s) in 0 ms 62 µs (server processing time: 0 ms 0 µs)
Statement 'CALL dbo.usp_GetOrdersByCustomerID(3429)'
successfully executed in 8 ms 522 µs (server processing time: 6 ms 892 µs)
Fetched 5 row(s) in 0 ms 93 µs (server processing time: 0 ms 0 µs)
When I execute the select statement with the hard coded parameter value, I get much faster results:
Statement 'SELECT TOP 20 C_F_NAME, C_L_NAME, C_EMAIL, O_ID, O_TOTAL, O_DTS, O_FM_DTS FROM dbo.Customer JOIN ...'
successfully executed in 4 ms 430 µs (server processing time: 2 ms 424 µs)
Fetched 5 row(s) in 0 ms 73 µs (server processing time: 0 ms 0 µs)
Statement 'SELECT TOP 20 C_F_NAME, C_L_NAME, C_EMAIL, O_ID, O_TOTAL, O_DTS, O_FM_DTS FROM dbo.Customer JOIN ...'
successfully executed in 4 ms 105 µs (server processing time: 2 ms 210 µs)
Fetched 5 row(s) in 0 ms 69 µs (server processing time: 0 ms 0 µs)
Statement 'SELECT TOP 20 C_F_NAME, C_L_NAME, C_EMAIL, O_ID, O_TOTAL, O_DTS, O_FM_DTS FROM dbo.Customer JOIN ...'
successfully executed in 4 ms 694 µs (server processing time: 2 ms 810 µs)
Fetched 5 row(s) in 0 ms 60 µs (server processing time: 0 ms 0 µs)
I have 500,000 rows in the Customers table and 2,500,000 rows in the Orders table. The tables are COLUMN tables.
Is there an optimization that I'm missing?
Regards,
Bill

Hi Bill,
Can you please try something:
tab_cust =
SELECT
   C_F_NAME,
            C_L_NAME,
            C_EMAIL
FROM    dbo.Customer
WHERE   C_ID = :C_ID;
tab_orders =
SELECT
            O_ID,
            O_TOTAL,
            O_DTS,
            O_FM_DTS
FROM    dbo.Orders ON C_ID = O_C_ID
WHERE   O_C_ID = :C_ID
SELECT TOP 20
   C_F_NAME,
            C_L_NAME,
            C_EMAIL,
            O_ID,
            O_TOTAL,
            O_DTS,
            O_FM_DTS
FROM    :tab_cust JOIN :tab_orders ON C_ID = O_C_ID
    ORDER   BY O_ID DESC;
END;
Expected behavior: The data set for each of the tables is filtered out and then joined. Although the filter is expected to be pushed to each of the joined tables even in your case, but this is worth the try.

Ravi
