Do we have any method to make first letter of every word as capital letter for a column in SAP HANA?
i.e "ask question" to "Ask Question"
With HANA 2 SPS3, there is a built in function called "Initcap"
SELECT INITCAP('that''s a new function') FROM DUMMY;
That'S A New Function
There is no builtin function for that on SQL level.
You could however write a user-defined function to do just that.
Possibly this site gives you a clue? I'm not familiar with SAP HANA but possibly you can label it as title sentence and do a case normalisation on it?
In T-SQL you could do something like this:
SELECT
UPPER(LEFT(ColumnA,1))+LOWER(RIGHT(ColumnA,(LEN(ColumnA)-1)))
FROM Table1;
You tell the DBMS to make the first letter in upper case, and the rest of the string in lower case. The LEN is needed because I assume the length of the string is not static and in the way of the script it is handled dynamically. The + is CONCAT in other dialects. Regarding whitespaces in ColumnA and the capitalization of the 2nd or more word in you column, I'm trying some stuff that Michael Valentine Jones described on 1-12-2006 here, alsee see part of the code beneath. I get back to this as soon as I figured this out. I'm not sure yet how the union all select statement works. Will take some days (due to the weekend). Anyway, maybe this helps you. Change the REPLACE of ',' with ' ' or something.
-- Create temp table to test inserting values into
create table #t (num int)
-- Create a comma delimited string to test with
declare #str varchar(500)
select #str = '4,2,7,7834,45,24,45,77'
--------------------------------------------------------
---- Code to load the delimited string into a table ----
--------------------------------------------------------
-- Create insert for comma delimited values
declare #sql varchar(8000)
select #sql = 'insert into #t select '+ replace(#str,',',' union all select ')
-- Load values from comma delimited string into a table
exec ( #sql )
I found a piece of T-SQL script that creates a function 'ProperCase' that will do the trick by calling the function in your select statement. See beneath. I foun it here: http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=47718 (by jsmith8858).
create function ProperCase(#Text as varchar(8000))
returns varchar(8000)
as
begin
declare #Reset bit;
declare #Ret varchar(8000);
declare #i int;
declare #c char(1);
select #Reset = 1, #i=1, #Ret = '';
while (#i <= len(#Text))
select #c= substring(#Text,#i,1),
#Ret = #Ret + case when #Reset=1 then UPPER(#c) else LOWER(#c) end,
#Reset = case when #c like '[a-zA-Z]' then 0 else 1 end,
#i = #i +1
return #Ret
end
And for example if you do a SELECT dbo.ProperCase ('ask question WHy iS tHAT'), then you get 'Ask Question Why Is That' as a result.
Hopefully this gets you on your way.

I'm trying to make procedure to select weekly music rank based on hits and likes.
create or replace procedure select_rank(
v_title IN music.title%TYPE,
v_release_date IN music.release_date%TYPE,
v_hit IN music.hit%TYPE
) is
v_cnt number := 0;
BEGIN
select music.title, music.release_date, count(melon_user.user_idx) as likes, music.hit
into v_rank, v_title, v_cnt, v_release_date, v_hit
from melon_user, user_like_music, music
where melon_user.user_idx = user_like_music.user_idx
and user_like_music.music_idx = music.music_idx
group by music.title, music.hit, music.release_date
order by count(melon_user.user_idx) desc, music.hit desc;
DBMS_OUTPUT.PUT_LINE('v_title: ' || v_title);
DBMS_OUTPUT.PUT_LINE('v_cnt: ' || v_cnt);
DBMS_OUTPUT.PUT_LINE('v_release_date: ' || v_release_date);
DBMS_OUTPUT.PUT_LINE('v_hit: ' || v_hit);
END select_rank;
/
But I keep getting error says
PLS-00403: expression 'V_RELEASE_DATE' cannot be used as an
INTO-target of a SELECT/FETCH statement
PLS-00403: expression 'V_RELEASE_DATE' cannot be used as an
INTO-target of a SELECT/FETCH statement
PLS-00403: expression 'V_RELEASE_DATE' cannot be used as an
INTO-target of a SELECT/FETCH statement
how do I fix this?
In the procedure's signature you have:
v_release_date IN music.release_date%TYPE,
v_release_date is an IN parameter and will be read only. If you want to assign values to it wthin the procedure and return them then make it an OUT (or IN OUT) parameter.
However, you have also:
Not declared the v_rank variable.
Your query appears likely to return multiple rows - SELECT .. INTO .. will only work for queries that return a single row. If this is the case then you either want to use BULK COLLECT INTO or return a cursor.
I have several Oracle functions that are similar to the one below. I don't know much about Oracle and although I have made in roads on a major query re-write. I'd like to ask for some help on how to convert this function to SQL Server 2008.
I have tried using the online conversion tool at www.sqlines.com and benefited from many pages there... but not successful in converting this function....
Thanks in advance, John

wPhID t_OfficePhoneID;
wPhID1 t_OfficePhoneID;
cursor cr_phone

select Office_PHONE_ID,IS_PHONE_PRIMARY

order by SEQ_NUMBER;

wPhID :=NULL;
wPhID1:=NULL;

Exit;
end if;
end loop;
if wPhID is NULL
then wPhID:=wPhID1;
end if;
return(wPhID);

end ;
To answer the question about the functions as written
If you just want to fix the cursor so it works, one problem is the two "fetch wp into;" statements. You are saying "fetch the data and put it into" and then not giving it anything to put it into. Declare a couple of variables, put the data into them, then later use the variables, not the code. You need one variable per item returned in your cursor definition, so one each for Office_PHONE_ID and IS_PHONE_PRIMARY.
Also, you are trying to declare variables (and the function) as t_OfficePhoneID, I suspect that should be something like INT OR BIGINT instead (whatever the table definition for the column is).
Declare #OP_ID INT, #ISPRIMARY CHAR(1) --Or whatever the column is
later (in two locations),
fetch wp into (#OP_ID, #ISPRIMARY);
then use #OP_ID instead of wp.Office_PHONE_ID, and so on.
HOWEVER, I would throw away all the code in the function after declaring #wPhID, and do something else. Cursors suck if you can get what you want with a simple set based request. If you work your way through the oracle code, it is doing the following:
Get the id of the first phone number marked primary (in sequence order). If it didn't find one of those, just get the id of the first non-primary phone number in sequence order. You can do that with the following
set #wPhID = select TOP 1 Office_PHONE_ID
from Office_PHONE
where Office_ID = #p_ID
order by CASE WHEN IS_PHONE_PRIMARY = 'Y' THEN 0 ELSE 1 END, SEQ_NUMBER;
Return #wPhID and you're done.
I used "CASE WHEN IS_PHONE_PRIMARY = 'Y' THEN 0 ELSE 1 END" in the order by because I don't know what other values are possible, so this will always work. If you know the only possible values are 'Y' and 'N', you could use something like the following instead
order by IS_PHONE_PRIMARY DESC, SEQ_NUMBER;
Thanks for looking...
I've spent hours researching this and I can't believe it's that difficult to do something in PL/SQL that is simple in TSQL.
I have a simple query that joins 2 tables:
Select DISTINCT
to_char(TO_DATE('1899123000', 'yymmddhh24')+ seg.NOM_DATE, 'mm/dd/yyyy') AS "Record Date"
, cd.CODE
, EMP.ID
, EMP.SHORT_NAME
FROM
EWFM.GEN_SEG seg join EWFM.SEG_CODE cd ON seg.SEG_CODE_SK = cd.SEG_CODE_SK
join EMP on seg.EMP_SK = EMP.EMP_SK
where NOM_DATE = vMyDate;
I use Toad Date Point and I'm querying against an Oracle Exadata source. The resulting query will be dropped into a visualization tool like QlikView or Tableau. I'd like to create a simple variable to use the the WHERE clause as you can see in the code.
In this example, NOM_DATE is an integer such as 42793 (2/27/2017) as you can see in the first row "Record Date". Nothing new here, not very exciting... Until... I tried to create a variable to make the query more dynamic.
I've tried a surprising variety of examples found here, all have failed. Such as:
declare
myDate number(8);
Begin
myDate := 42793;
--Fail ORA-06550 INTO Clause is expected
variable nomDate NUMBER
DEFINE nomDate = 42793
EXEC : nomDate := ' & nomDate'
...where NOM_DATE = ( & nomDate) ;
--ORA-00900: invalid SQL statement
and
variable nomDate NUMBER;
EXEC nomDate := 42793;
select count(DET_SEG_SK) from DET_SEG
where NOM_DATE = :nomDate;
--ORA-00900: invalid SQL statement
and several more.. hopefully you get the idea. I've spent a few hours researching stackoverflow for a correct answer but as you can see, I'm asking you. From simple declarations like "Var" to more complex " DECLARE, BEGIN, SELECT INTO...." to actually creating Functions, using cursors to iterate the output.... I still can't make a simple variable to use in a Where clause.
Please explain the error of my ways.
--Forlorn SQL Dev
Since you are using an implicit cursor, you have to select then INTO variables. Now I d not know the data types of you variables, so I have just guessed in this example below, but hopefully you get the point.
Two other things I should mention
Why are you TO_CHARing you DATE. Just use a DATE datatype. Also, I think your format mask is wrong too 1899123000 does not match yymmddhh24.
In explicit cursor expects exactly one row; no rows and you get NO_DATA_FOUND; more than one and you get TOO_MANY_ROWS
Declare
myDate number(8) := 42793;
/* These 4 variable data types are a guess */
v_record_date varchar2(8);
v_cd_code varchar2(10);
v_emp_id number(4);
v_emp_short_name varchar2(100);
BEGIN
Select DISTINCT to_char(TO_DATE('1899123000', 'yymmddhh24')
+ eg.NOM_DATE, 'mm/dd/yyyy') AS "Record Date"
, cd.CODE
, EMP.ID
, EMP.SHORT_NAME
INTO v_record_date, v_cd_code, v_emp_id, v_emp_short_name
FROM EWFM.GEN_SEG seg
join EWFM.SEG_CODE cd
ON seg.SEG_CODE_SK = cd.SEG_CODE_SK
join EMP
on seg.EMP_SK = EMP.EMP_SK
where NOM_DATE = myDate;
END;
/
VARIABLE vMyDate NUMBER;
BEGIN
:vMyDate := 42793;
END;
/
-- or
-- EXEC :vMyDate := 42793;
SELECT DISTINCT
TO_CHAR( DATE '1899-12-30' + seg.NOM_DATE, 'mm/dd/yyyy') AS "Record Date"
, cd.CODE
, EMP.ID
, EMP.SHORT_NAME
FROM EWFM.GEN_SEG seg
join EWFM.SEG_CODE cd
ON seg.SEG_CODE_SK = cd.SEG_CODE_SK
join EMP
on seg.EMP_SK = EMP.EMP_SK
WHERE NOM_DATE = :vMyDate;
You put the variables with getter and setter in a package.
Then use a view that uses the package getter
Personally I prefer to use a collection that way I can do a select * from table (packagage.func(myparam))
Is there a fairly simple way to take an input parameter containing a comma seperated list of prefixes and return a cursor based on a select statement that uses these?
i.e. (Pseudocode)
PROCEDURE get_by_prefix(p_list_of_prefixes IN varchar2, r_csr OUT SYS_REFCURSOR)
IS
BEGIN
OPEN r_csr FOR
SELECT * FROM my_table where some_column LIKE (the_individual_fields_from p_list_of_prefixes ||'%')
END
I've tried various combinations, and now have two problems - coercing the input into a suitable table (I think it needs to go into a table type rather than a VARCHAR2_TABLE), and secondly getting the like clause to be effectively a SELECT from an internal 'pseudotable'...
EDIT: It seems that people are suggesting ways to use 'IN' with a set of potential values - whereas Im looking at using LIKE. I could use a similar technique - building up dynamic SQL, but was wondering if there isnt a more elegant way...
PL/SQL has no concept of a comma-separated list and no built-in splitter as in Perl etc, so you'll have to use one of the hand-rolled methods such as this one:
https://stewashton.wordpress.com/2016/08/01/splitting-strings-surprise
(Other methods are available.) Then it's just a matter of either populating a collection in one step and using it in the next, or else combining the two as something like this:
declare
p_list_of_prefixes varchar2(100) := 'John,Jim,Jules,Janice,Jenny';
begin
open :refcur for
with params as
( select x.firstname
from xmltable(
'ora:tokenize($X, "\,")'
passing p_list_of_prefixes as x
columns firstname varchar2(4000) path '.'
) x
)
, people as
( select 'Dave Clark' as fullname from dual union all
select 'Jim Potter' from dual union all
select 'Jenny Jones' from dual
)
select x.firstname, p.fullname
from params x
left join people p on p.fullname like x.firstname || '%';
end;
Output:
FIRSTNAME FULLNAME
-------------- -----------
John
Jim Jim Potter
Jules
Janice
Jenny Jenny Jones
Using LIKE the way you want is easy, but it is the wrong solution. (See my Comment under the original post).
Anyway - if by order of your superiors, or some other semi-legitimate reason, you must use a LIKE condition, it should look something like this:
... where ',' || p_list_of_whatever || ',' like '%,' || some_column || ',%
Concatenating commas at both ends of both sides of the comparison is needed, because you don't want Jo in the column to match John in the input list. Start from there and you will see why you need the commas on the right-hand side, and then follow from there and you will see why you need them on the left also.
In a view i under the SOURCE column I have the following values.
SRC - TERM - randomtext - LOCATION (Just a FYI on the format of the source column)
ABC DE RANDOMJIBBERISH MORE RANDOMJIBBERISH FORWARD
ARY HES RANDOMJIBBERISH MORE RANDOMJIBBERISH BACKWARD
IGHE UER RANDOMJIBBERISH MORE RANDOMJIBBERISH LEFT
Now I have a query that needs to lookup on that view BASED on the source. This one works perfectly fine.
SELECT
t.DATE_, t.PX_LAST
FROM
THIS.TABLE_NEW t
WHERE
t.DATE_ >= '2003-03-02'
AND t.DATE_ <= '2013-03-02'
AND t.SOURCE LIKE 'ABC DE % FORWARD' --Where the magic happens
AND t.SOURCE LIKE '%'||'1M'||'%'
AND t.PX_LAST is NOT NULL
ORDER BY
t.DATE_ ASC;
Now, the issue is, when I try to implement this in a stored procedure, I will need to insert the percent sign in the parameters I get. This doesn't work, particularly the part where it looks for the source using the inSource
PROCEDURE Get_It
(
inSource VARCHAR2,
inStartDate DATE,
inEndDate DATE,
inLength VARCHAR2,
inRC1 OUT SYS_REFCURSOR
) AS
BEGIN
OPEN inRC1 FOR
SELECT t.DATE_, t.PX_LAST
FROM THIS.TABLE_NEW t WHERE
t.DATE_ >= inStartDate
AND t.DATE_ <= inEndDate
AND t.SOURCE LIKE inSource --Where the magic needs to happen
AND t.SOURCE LIKE '%'||length||'%'
AND t.PX_LAST is NOT NULL
ORDER BY t.DATE_ ASC;
END GET_IT;
So basically I need to insert a percent sign in the MIDDLE of the string (inSource), between the last and second-last word, at all times. I was able to do it in the query because I can manually put it in the string, but in the actual stored procedure I don't know how I can manipulate the string.
Assuming you want to pass in a value of inSource like 'ABC DE FORWARD' and have the procedure translate that to 'ABC DE % FORWARD' - with the % always between the second and third word - then you can mess around with chopping up and reconstructing the string, or you can do a simple regexp_replace():
AND t.SOURCE LIKE regexp_replace(inSource, ' ', ' % ', 1, 2)
AND t.SOURCE LIKE '%'||inLength||'%'
This replaces a space with a space-padded percentage sign, starting as position 1 (i.e. the start of the string) and only applying to the second instance - so it skips over the first space and only affects the one between the second and third words.
To demonstrate this:
select regexp_replace('ABC DE FORWARD', ' ', ' % ', 1, 2)
from dual;
REGEXP_REPLACE('
----------------
ABC DE % FORWARD
Looks to me that your query is fine but your inLength parameter is not being used correctly in the cursor definition.
Based on your edit clarification there are two possible solutions.
First option: Pass inSource as two varchars which would be all of the string up until the space and then the last word
PROCEDURE Get_It
(
inSourceFirst VARCHAR2,
inSourceLast VARCHAR2,
inStartDate DATE,
inEndDate DATE,
inLength VARCHAR2,
inRC1 OUT SYS_REFCURSOR
) AS
BEGIN
OPEN inRC1 FOR
SELECT t.DATE_, t.PX_LAST
FROM THIS.TABLE_NEW t WHERE
t.DATE_ >= inStartDate
AND t.DATE_ <= inEndDate
AND t.SOURCE LIKE inSourceFirst || '%' || inSourceLast
AND t.SOURCE LIKE '%'|| inLength ||'%'
AND t.PX_LAST is NOT NULL
ORDER BY t.DATE_ ASC;
END GET_IT;
Second option: Use regexp_substr() function More here. Your inSource string would then be replace by regexp_replace with two regexp_substr function call grabbing what is before and after the space with the & character appended in between. Something like...
regexp_substr('SPACE MAN BEAR PIG DOG CAT','[^ ]+{4}',1,5) || ' % ' || regexp_substr('SPACE MAN BEAR PIG DOG CAT','[^ ]+',1,6)
