Special Characters in SELECT Query

What is the right way of using Special character '*' in SELECT Query.
Say..
SELECT PSPID FROM PROJ
                INTO TABLE IT_P_PROJ
                WHERE PSPID EQ P_PROJ
In this P_PROJ is SS*. No value is populating for this . Pls suggest where am I going wrong?

hi
chk this out
Field descriptor
Variants:
1. f
2. dbtab~field
3. tabalias~field
Effect
Used in the SELECT, OPEN CURSOR, UPDATE and DELETE commands to uniquely identify columns (fields) of database tables and views specified in FROM clauses.
Variant 1
f
Effect
Identifies the field f of a database table or view specified in the FROM clause. The name f may only occur once in all database tables or views, that is, it must be unique. You use this variant particularly when there is only one table specified in the FROM clause. If the uniqueness of the field cannot be guaranteed, you must use variant 2 or 3.
Example
Output a list of all customers whose names begin with 'A':
DATA: WA_SCUSTOM TYPE SCUSTOM.
<b>SELECT * FROM SCUSTOM INTO WA_SCUSTOM WHERE NAME LIKE 'A%'.
WRITE: / WA_SCUSTOM-ID, WA_SCUSTOM-NAME.
ENDSELECT</b>.
Variant 2
dbtab~field
Effect
Identifies field f in the database table or view dbtab specified in the FROM clause. The combination dbtab~field must be unique. You can use this variant if table dbtab only appears once in the FROM clause. If this uniqueness cannot be assured, you must use variant 3.
Example
Output a list of all customers whose names begin with 'A':
DATA: WA_SCUSTOM TYPE SCUSTOM.
<b>SELECT * FROM SCUSTOM INTO WA_SCUSTOM
         WHERE SCUSTOM~NAME LIKE 'A%'.
WRITE: / WA_SCUSTOM-ID, WA_SCUSTOM-NAME.
ENDSELECT.</b>
Variant 3,,tabalias~field
Effect
Identifies field f in the table or view with the alias name tabalias specified in the FROM clause.
Example
Output a list of all customers whose name begins with 'A':
DATA: WA_SCUSTOM TYPE SCUSTOM.
SELECT * FROM SCUSTOM AS T INTO WA_SCUSTOM WHERE T~NAME LIKE 'A%'.
WRITE: / WA_SCUSTOM-ID, WA_SCUSTOM-NAME.
ENDSELECT.

friends
thanks for ur time and effort that u gave to reply to my problem.
But my main problem is that when my application (VC++ 7) fires the following query in the oracle database , it does not return any rows.
SELECT count(*) FROM ORGANISATION WHERE UPPER(ORGANISATION.ORGANISATIONNAME)
LIKE N'β%' ORDER BY ORGANISATION.ORGANISATIONNAME
the above question in the previous thread was just to check on sql plus as it's editor does not support unicode characters.

How to use : bind character in DB adapter Select Query SOA11g. Getting Error code :17003 .java.sql.SQLException: Invalid column index error

Hi All,
The Actual query to perform is below.
SELECT name,number from emp WHERE CASE WHEN :1='T' AND term_date IS Not NULL THEN 1 WHEN :1='A' AND term_date IS NULL THEN 1 WHEN :1='ALL' THEN 1 ELSE 1 END = 1;
I have tried in DB adapter like below as a parameter for :1 as #vInputParam
SELECT name,number from emp WHERE CASE WHEN #vInputParam='T' AND term_date IS Not NULL THEN 1 WHEN #vInputParam='A' AND term_date IS NULL THEN 1 WHEN #vInputParam='ALL' THEN 1 ELSE 1 END = 1;
Getting Error code :17003 .java.sql.SQLException: Invalid column index error.
Please suggest me on using ':' bind character in DB adapter Select Query SOA11g.
Can someone help me on this please?
Thanks,
Hari

Hi,
Could you please make sure your binding style(Oracle Positional,Oracle named..etc) of the Seeded VO and Custom Vo are same.
This is the option you will get when you are extending your vo. So make sure that both are same.
You can refer the below link too
VO extension leads to "Invalid column index" exception

Issue in select query with where clause

Hi guys,
I'm facing an issue while using select query with the where clause. When I'm selecting all the data from the table it returns the correct result. But when I'm using the where clause to get the specific rows from the table it returns no rows. But the data I'm trying to fetch using the where condition exists in the table.
Here is my query which causing the issue,
select * from mytable where myfield = 'myvalue'
But if I use the following query it returns the result correctly.
select * from mytable
Also the myfield value 'myvalue' exists in the table.
I have tried by running this query in both SQL Developer and SQL Plus. I have tried this query in mssql as well. It works perfectly and returns correct result sets for both the queries I have mentioned above. I'm unable to predict the issue as I'm new to ORACLE. Please help.
Thanks,
Ram.

Hi Ram,
I experienced an issue similar to this with a varchar2 field. Some of our records had a hidden newline character at the end of them, which was making queries like the one below fail:
select * from employees
where email = '[email protected]'The best way I found to detect this was to use
select 'XX'||email||'XX' from employeesTo make sure that there were no newlines. But that is just a guess. If you could provide some example table data and the outputs of your selects, it would be helpful.

Select query with secondary index

hi,
i have a report which is giving performance issues on a perticular select query on KONH table.
the select query doesnt use the primary key fields and table already has around 19 million entries.So there was a secondary index created for the fields in the table.
now, KONH is a client specific table, and hence has MANDT as the first field. when the table is not indexed it is sorted according to the order of fields, like first MANDT, then primary key fields and then remaining fields.. (correct me if i am wrong)
but the secondary index created doesnt has MANDT in it..(yea, a mistake! )...
but instead of correccting the secondary index, i am told to change the select query..
so, i used a "client specific" syntax to sort the issue.. but i dont understand whre i should put the "where mandt eq sy-mandt" clause..
should i put it right after all my secondary index fields are over? or what happens to the order of fields which are not present in the list of secondary index?
kindaly help.
thanx.

Hi chinmay kulkarni,
its better if you can ask concerned person to add MANDT field in your index as well....
Indexes and MANDT
If a table begins with the mandt field, so should its indexes. If a table begins with mandt and an index doesn't, the optimizer might not use the index.
Remember, if you will, Open SQL's automatic client handling feature. When select * from ztxlfa1 where land1 = 'US' is executed, the actual SQL sent to the database is select * from ztxlfa1 where mandt = sy-mandt and land1 = 'US'. Sy-mandt contains the current logon client. When you select rows from a table using Open SQL, the system automatically adds sy-mandt to the where clause, which causes only those rows pertaining to the current logon client to be found.
When you create an index on a table containing mandt, therefore, you should also include mandt in the index. It should come first in the index, because it will always appear first in the generated SQL.
Index: Technical key of a database table.
Primary index: The primary index contains the key fields of the table and a pointer to the non-key fields of the table. The primary index is created automatically when the table is created in the database.
Secondary index: Additional indexes could be created considering the most frequently accessed dimensions of the table.
Structure of an Index
An index can be used to speed up the selection of data records from a table.
An index can be considered to be a copy of a database table reduced to certain fields. The data is stored in sorted form in this copy. This sorting permits fast access to the records of the table (for example using a binary search). Not all of the fields of the table are contained in the index. The index also contains a pointer from the index entry to the corresponding table entry to permit all the field contents to be read.
When creating indexes, please note that:
An index can only be used up to the last specified field in the selection! The fields which are specified in the WHERE clause for a large number of selections should be in the first position.
Only those fields whose values significantly restrict the amount of data are meaningful in an index.
When you change a data record of a table, you must adjust the index sorting. Tables whose contents are frequently changed therefore should not have too many indexes.
Make sure that the indexes on a table are as disjunctive as possible.
(That is they should contain as few fields in common as possible. If two indexes on a table have a large number of common fields, this could make it more difficult for the optimizer to choose the most selective index.)
For Example...
SELECT KUNNR KUNN2 INTO TABLE T_CUST_TERR
FROM KNVP CLIENT SPECIFIED
WHERE MANDT = SY-MANDT " here MANDT shd be first
AND KUNN2 IN S_TERR
AND PARVW LIKE 'Z%'.
Accessing tables using Indexes
The database optimizer decides which index on the table should be used by the database to access data records.
You must distinguish between the primary index and secondary indexes of a table. The primary index contains the key fields of the table. The primary index is automatically created in the database when the table is activated. If a large table is frequently accessed such that it is not possible to apply primary index sorting, you should create secondary indexes for the table.
The indexes on a table have a three-character index ID. '0' is reserved for the primary index. Customers can create their own indexes on SAP tables; their IDs must begin with Y or Z.
If the index fields have key function, i.e. they already uniquely identify each record of the table, an index can be called a unique index. This ensures that there are no duplicate index fields in the database.
When you define a secondary index in the ABAP Dictionary, you can specify whether it should be created on the database when it is activated. Some indexes only result in a gain in performance for certain database systems. You can therefore specify a list of database systems when you define an index. The index is then only created on the specified database systems when activated

How to truncate a field in a Select Query

Hello Gurus,
I am new in SAP, i have a question i am making an appointment letter in SMARTFORMS , in global declaration (initialization) i am using a select query
SELECT SINGLE BET01 FROM PA0008 INTO G_BET01 WHERE PERNR = WA_PERNR.
where BET01 is the Amount field which is getting printed in the smart form but its takes 5 to 6 character blank spaces in the printing time, i want to truncate this space (remove this space ) in the print time , please tell me how to remove this space , the field size is 13 , how can i reduce the field size in my smartform query. please help . G_BET01 is a variable

Maybe you can use this.
DATA: d_char(15).
WRITE G_BET01 TO d_char CURRENCY 'XXX'.
'Then you can remove the spaces using :

Can we handle exceptions for the expressions in select query?

Hi all,
Can we handle exceptions for the expressions in select query.
I created a view, there I am extracting a substring from a character data and expected that as a number.
For example consider the following query.
SQL> select to_number( substr('r01',2,2) ) from dual;
TO_NUMBER(SUBSTR('R01',2,2))
1
Here we got the value as "1".
Consider the following query.
SQL> select to_number( substr('rr1',2,2) ) from dual;
select to_number( substr('rr1',2,2) ) from dual
ORA-01722: invalid number
For this I got error. Because the substr returns "r1" which is expected to be as number. So it returns "Invalid number".
So, without using procedures or functions can we handle these type of exceptions?
I am using Oracle 10 G.
Thanks in advance.
Thank you,
Regards,
Gowtham Sen.

How to use offset in select query

Suppose i have data like ssonje     00000001 as a one field in database table . i have to segregate this two data. how should I do this.the first part is of 12 characters and the last is of 10 character long.

Hi Naveen,
I am again in trouble, Now the requirement were changed. I am sending you the code which i had implemented.
Now, the user enter username(ie UNAMED) and document id (ie. TEMPD) and the output should be doucment id, which has been search through database table RFDT , field SRTFD, this field contains both the username and the document id.
That means: suppose user enters UNAMED as SSONJE and TEMPD as 0000000030, then i want to fier the select query from RFDT on field SRTFD and get only the document id of that user which user enter on input field-UNAMED.
i had tried but result were not coming.
please go through the code.
data:uname type UF05A-UNAMD.
data:temp type UF05A-TEMPD.
TYPES: BEGIN OF TEITAB_RFDT,
       SRTFD TYPE RFDT-SRTFD,
       END OF TEITAB_RFDT.
DATA: ITAB_RFDT TYPE TABLE OF TEITAB_RFDT.
DATA: WA_RFDT TYPE TEITAB_RFDT.
DATA: STR(22) TYPE c.
SELECT-OPTIONS:UNAMED FOR uname,
TEMPD FOR TEMP.
UNAMED-option = 'CP'.
append UNAMED.
CONCATENATE UNAMED TEMPD INTO STR.
SELECT SRTFD FROM RFDT INTO CORRESPONDING FIELDS OF TABLE ITAB_RFDT WHERE SRTFD eq str.
LOOP AT ITAB_RFDT INTO WA_RFDT.
SPLIT WA_RFDT AT SPACE INTO STR1 STR2.
WRITE: / STR1,STR2.
ENDLOOP.
Please mentioned what is the way to do this.
Thanks

Internal table with same variable and one select query

        POSNR like lips-posnr,        " delivery item
        KUNNR LIKE LIKP-KUNNR,        "ship quantity
END OF IT_ORDERDETAILS.
Where VBELN field is in VBAK and LIKP table.
VBELN in VBAK table = order #
VBELN in LIKP table is = Delivery #
I want to use join to fetch data in single select query.
Below is the select query

left outer JOIN LIPS ON ( VBAKVBELN = LIPSVGBEL )
join LIKP on ( LIPSVBELN = LIKPVBELN )
WHERE VBAK~ERDAT IN CR_DATE.
I am getting error in the query.
Please suggest.
Thanks,
Rajesh

Hi rajesh.nayakbola,
although this is not quite the right place for this, let me give you some notes:
1. Code should be
formatted as code
by markin it with mouse and use above <> button.
2. Internal tables shoult not be declared using OCCURS clause - this is last century style
3. Internal tables do not need and should not have a header line, they should use TYPES for declaration
4. Data should not be declared using LIKE: If they refer to dictionary TYPES, use TYPE. LIKE is only mandatory for data objects declared in your program, i.e. DATA IT_some_ORDERDETAILS like IT_ORDERDETAILS.
5. If you get an error here, never write "I am getting error" but copy and paste the error message fully.
- The fields in brackets in the INTO clause never have ~ character, there is no IT_ORDERDETAILS~vbak, only IT_ORDERDETAILS-vbeln
It could be something like this:
TYPES:
BEGIN OF TY_ORDERDETAILS,
VBELN TYPE VBAK-VBELN, "Order number
BSTNK TYPE VBAK-BSTNK, "customer PO
ERDAT TYPE VBAK-ERDAT, " Order created date
MATNR TYPE VBAP-MATNR, "Sales order line item
KWMENG TYPE VBAP-KWMENG, "Quantity
D_VBELN TYPE likp-vbeln, " delivery no
POSNR TYPE lips-posnr, " delivery item
KUNNR TYPE LIKP-KUNNR, "ship quantity
END OF TY_ORDERDETAILS.
DATA:
IT_ORDERDETAILS TYPE TABLE OF TY_ORDERDETAILS.
SELECT VBAK~VBELN
VBAK~BSTNK
VBAK~ERDAT
VBAP~MATNR
VBAP~KWMENG
likp~vbeln AS D_VBELN
lips~posnr
LIKP~KUNNR
INTO CORRSPONDING FIELDS OF TABLE IT_ORDERDETAILS
FROM VBAK left outer JOIN VBAP ON ( VBAK~VBELN = VBAP~VBELN )
left outer JOIN LIPS ON ( VBAK~VBELN = LIPS~VGBEL )
join LIKP on ( LIPS~VBELN = LIKP~VBELN )
WHERE VBAK~ERDAT IN CR_DATE.

Performance Tuning on a Select Query

Hi,
We have a select statement as mentioned below.
      SELECT loobj1 gpart vkont proid tdate lotyp lockr
      INTO TABLE tb_dfkklocks
         FROM dfkklocks
         FOR ALL ENTRIES IN tb_fkkvkp
         WHERE
        lotyp = '02'
         AND   proid = '01'
         AND   lockr >= '0'
         AND   lockr <= '9'
         AND   gpart = tb_fkkvkp-gpart
         AND   vkont = tb_fkkvkp-vkont.
We have Primary key as shown below.
CLIENT
LOOBJ1
LOTYP
PROID
LOCKR
FDATE
TDATE
GPART
VKONT
We have a secondary index only on TDATE. What can be the ideal select stement to improve the performance?
Regards,
Lijo Joseph

Hi Lijo,
Couple of pointers from my end.
1). Try avoiding a FOR ALL ENTRIES if the base table is huge. Instead use a array fetch and pick up more data instead of trying to restrict the data using a FOR ALL ENTRIES as this does a LOOP on the database while selecting the data.
So i would suggest not use FOR ALL ENTRIES if the base table is huge. So analyse before using a select query.
2). It is actually very difficult to mention which option is better. I would say that it all depends on the scenario. What amount of data is to be read, from which table it is being read, what kind of processing is required on database,..... and many more analysis goes to write a an efficient select statement.
3). If i am not wrong i think if you are using a FOR ALL ENTRIES and dont specify the key completely then there is no gaurentee that you fetch all the unique records. The system will compare all the character fields as a KEY field and it will not fetch all the records. So while using a FOR ALL ENTRIES its recommended to use all the key fields.
4). If you would like to really spend time and work on a efficient select statement then try using the tcode ST05 --> Select the button EXPLAIN SQL REQUEST.
type in your select query and see what is the cost of the select statement fired on the database. This will help you to select the best statement. This is a very useful tool if we have complex select statements.
Hope this info is helpful.
Cheers

Pls help me in select query......

My problem is...
I have to use a select query in such a manner that i can compare the last 8 characters or ignore the first one...

Hi Aarif,
Try this :
parameters :
p_field1(30) type c.
Data :
w_string(8) type c,
w_firstchar type c,
t_itab ......,
fs_itab like line of itab.
w_string = p_field1+22(8)      " passing last 8 chars into w_string
w_firstchar = p_field1+0(1).
select *
   from DataTab Name
   into table IntTab Name
where <field name> eq w_string
      or <field name> ne w_firstchar.
If you are accepting the value from user then first pass the last 8 characters into w_string and in your select query get the fields where the value is equal to w_string. And pass the first character into another field and to ignore write NE W_FIRSTCHAR.
There can be other methods also. This is one of the ways.
Regards,
Swapna.
