I'm pulling a query that is giving me results that look like this "05629003". I need my query to return the results like this "056290-03". I figure I can get this done with a combination of SUBSTR and CONCAT functions, but was curious to see if there was an easier way to insert a dash to a specific spot. The results will always be 8 digits long and I will always need the dash before the last two digits.
I think you want the INSERT scalar function (not to be confused with the INSERT statement)
Here's an example that produces the value you are looking for:
select INSERT('05629003', 7,0,'-')
FROM SYSIBM.SYSDUMMY1
I tested, and it worked on both Linux/Unix/Windows 9.7, and z/OS 10.

I have a database with MANY out-of-date file locations. The difference between the out-of-date file locations and the correct locations is simply the left-side of the address. So, I am attempting to take the left-side off and replace it with the correct string. But, I can't get there because my query is altering the right-side of the address.
This query is made using "vfpoledb."
SELECT RIGHT(LINK,LEN(LINK)-8) ,LEN(LINK)-8,RIGHT(LINK,77),LINK
FROM LINKSTORE
WHERE DOCLBL = "V46145002A"
This query returns the following:
EXP1:
\SHARES\DATA\QMS\QMS DATA\TRACKING FILES\REMOTEENTRIES\V46145 216447
EXP2:
77
EXP3:
\SHARES\DATA\QMS\QMS DATA\TRACKING FILES\REMOTEENTRIES\V46145 216447-002A.PDF
LINK:
\\SERVER\SHARES\DATA\QMS\QMS DATA\TRACKING FILES\REMOTEENTRIES\V46145 216447-002A.PDF
I don't understand why EXP1 and EXP3 are giving different results. EXP3 is what I'm looking for EXP1 to return. If I could get that, I could append the correct left-hand-side and create an update query to fix everything.
Edit:
Even when changing the query to:
SELECT RIGHT(LINK,LEN(LINK)) ,LEN(LINK)-8,RIGHT(LINK,77),LINK
FROM LINKSTORE
WHERE DOCLBL = "V46145002A"
The link still cuts off at the same point, which is odd because expression_3 which still uses Right(), but manually provides the length instead of using Len() does not do this.
Furthermore, it seems that when I run the query to include all results:
SELECT RIGHT(LINK,LEN(LINK)) ,LEN(LINK)-8,RIGHT(LINK,77),LINK
FROM LINKSTORE
WHERE 1=1
All values returned by Exp1 are equal in length even though Exp2 and Link are different in size.
So back to the problem, how can I run a query to replace the left-side with the correct server if I can't separate them out?
OK this is tricky, I did some Foxpro 20 years ago but don't have it to hand.
Your SELECT statement looks OK to me. In the comments under the question Thomas G created this DbFiddle which shows that in a 'normal' dbms, your SELECT statement gives the result you are expecting: https://dbfiddle.uk/?rdbms=sqlserver_2017&fiddle=37047d2b7efb91aaa029fa0fb98eea24
So the problem must be something FoxPro/dBase specific rather than a problem with your SELECT statement.
Reading up I see people say that with FoxPro always use ALLTRIM() when using RIGHT() or LEN() on table fields because the data gets returned padded with spaces. I don't see how that would cause the exact bug you're seeing but you could try this maybe:
SELECT RIGHT(ALLTRIM(LINK),LEN(ALLTRIM(LINK))-8) ,LEN(ALLTRIM(LINK))-8,RIGHT(ALLTRIM(LINK),77),ALLTRIM(LINK)
FROM LINKSTORE
WHERE DOCLBL = "V46145002A"
edit: OK I got a better idea - are there other rows in your result set?
According to this: https://www.tek-tips.com/viewthread.cfm?qid=1706948 ... when you do SELECT (expr) in FoxPro whatever the length of the expr in the first row becomes that max length for that 'field' and so all subsequent rows get truncated to that length. Makes sense in a crazy 1970s sort of way.
So perhaps you have a row of data above the one we are talking about which comes out at 68 chars long and so every subsequent value gets truncated to that length.
The way around it is to pad your expression results with CAST or PADR:
SELECT PADR(RIGHT(ALLTRIM(LINK),LEN(ALLTRIM(LINK))-8),100),LEN(ALLTRIM(LINK))-8,PADR(RIGHT(ALLTRIM(LINK),77),100),LINK
FROM LINKSTORE
WHERE DOCLBL = "V46145002A"
Or same without the ALLTRIM()
SELECT PADR(RIGHT(LINK,LEN(LINK)-8),100),LEN(LINK)-8,PADR(RIGHT(LINK,77),100),LINK
FROM LINKSTORE
WHERE DOCLBL = "V46145002A"
I have a report (built using SSRS) that uses a multi-value parameter.
I want to add a Filter onto my SQL Query WHERE FieldA is LIKE any of the values stored in the parameter.
So FieldA might have the following values:
BOBJAMESLOUISE
MARYBOB
JENNY
JOHNLOUISEJAMES
BOB
JENNYJAMESMIKE
And #ParamA might have the following values:
Bob, Louise
Therefore in this example only records 1, 3, 4 and 5 should be returned
Thanks to any help in advance :)
P.S I'm using SQL Server 2008
You will want to implement a function like the split function. This can take a comma separated value list and separate it into rows like you want.
Below is a link for a couple of different versions, any of them will work for you. It also tells you how to use it.
Split Function
I am guessing its not the spiting sting part that is the issue since just googling for SQL split string you can find a lot of example. In your case what you would want after the split string is something like this. Assuming that the split string function you end up using returns a table of values Here is what your comparison query for with field A would look like.
SELECT * FROM YourTableWithFieldA WHERE (#ParamA IS NULL OR EXISTS ( SELECT * FROM YourSplitFunctionThatReturnsATableOfValues(#ParamA) SplitTable WHERE (FieldA Like '%'+SplitTable.Value+'%')))
I'm trying to retrieve all columns that start with any non alpha characters in SQlite but can't seem to get it working. I've currently got this code, but it returns every row:
SELECT * FROM TestTable WHERE TestNames NOT LIKE '[A-z]%'
Is there a way to retrieve all rows where the first character of TestNames are not part of the alphabet?
Are you going first character only?
select * from TestTable WHERE substr(TestNames,1) NOT LIKE '%[^a-zA-Z]%'
The substr function (can also be called as left() in some SQL languages) will help isolate the first char in the string for you.
edit:
Maybe substr(TestNames,1,1) in sqllite, I don't have a ready instance to test the syntax there on.
Added:
select * from TestTable WHERE Upper(substr(TestNames,1,1)) NOT in ('A','B','C','D','E',....)
Doesn't seem optimal, but functionally will work. Unsure what char commands there are to do a range of letters in SQLlite.
I used 'upper' to make it so you don't need to do lower case letters in the not in statement...kinda hope SQLlite knows what that is.
try
SELECT * FROM TestTable WHERE TestNames NOT LIKE '[^a-zA-Z]%'
SELECT * FROM NC_CRIT_ATTACH WHERE substring(FILENAME,1,1) NOT LIKE '[A-z]%';
SHOULD be a little faster as it is
A) First getting all of the data from the first column only, then scanning it.
B) Still a full-table scan unless you index this column.
How do I convert a special chars like '#' to RAW format in Oracle?I need it for searching in the blob like this.
following code is giving me all rows in table as a result
dbms_lob.instr(gob_a_document, utl_raw.cast_to_raw('C#')) <> 0)
Or is there a better way?
I tried your code out, and I think it's correct for that line. On Oracle 11.2.0.1, I used your code to do something basically the same:
select v.*
from V_INCOMING_MAIL v
where dbms_lob.instr(v.message_text, utl_raw.cast_to_raw('C#'),1,1) <> 0;
This selected 9 rows out of the 15 thousand in the view. From an ad-hoc sampling of those rows and some others, that seems to be working OK.
So, perhaps the problem lies in the other lines in the SQL statement?
I am trying to sort £ along with other special characters, but its not sorting properly.
I want that string to be sorted along with other strings starting with special characters. For example I have four strings:
&!##
££$$
abcd
&#$%.
Now its sorting in the order: &!##, &#$%, abcd, ££$$.
I want it in the order: &!##, &#$%, ££$$, abcd.
I have used the function order by replace(column,'£','*') so that it sorts along with strings starting with *. Although this seems to work while querying the DB, when used in code and deployed the £ gets replaced by �, i.e. (replace(column,'�','*') in the query, and doesn't sort as expected.
How to resolve this issue? Is there any other solution to sort the pound symbol/£? Any help would be greatly appreciated.
You seem to have two problems; performing the actual sort, and (possibly) how the £ symbol appears in the results in your code. Without knowing anything about your code or client or environment it's rather hard to guess what you might need to change, but I'd start by looking at your NLS_LANG and other NLS settings at the client end. #amccausl's link might be useful, but it depends what you're doing. I suspect you'll find different values in nls_session_parameters when queried from SQL*Plus and from your code, which may give you some pointers.
The sorting itself is slightly clearer now. Have a look at the docs for Linguistic Sorting and String Searching and NLSSORT.
You can do something like this (with a CTE to generate your data):
with tmp_tab as (
select '&!##' as value from dual
union all select '££$$' from dual
union all select 'abcd' from dual
union all select '&#$%' from dual
)
select * from tmp_tab
order by nlssort(value, 'NLS_SORT = WEST_EUROPEAN')
VALUE
------
&!##
&#$%
££$$
abcd
4 rows selected.
You can get sort values supported by your configuration with select value from v$nls_valid_values where parameter = 'SORT', but WESTERN_EUROPEAN seems to do what you want, for this sample data anyway.
You can see the default sorting in your current session with select value from nls_session_parameters where parameter = 'NLS_SORT'. (You can change that with an ALTER SESSION, but it's only letting me do that with some values, so that may not be helpful here).
You need to make sure your application code is all proper UTF-8 (see http://htmlpurifier.org/docs/enduser-utf8.html for more details)
Seems like your issue is with db characterset, or difference in charactersets between the app and db. For Oracle side, you can check by doing:
select value from sys.nls_database_parameters where parameter='NLS_CHARACTERSET';
If this comes up ascii (like US7ASCII), then you may have issues storing the data properly. Even if this is the charset, you should be able to insert and retrieve sorted (binary sort) by using nvarchar2 and unistr (assuming they conform to your NLS_NCHAR_CHARACTERSET, see above query but change parameter), like:
create table test1(val nvarchar2(100));
insert into test1(val) values (unistr('\00a3')); -- pound currency
insert into test1(val) values (unistr('\00a5')); -- yen currency
insert into test1(val) values ('$'); -- dollar currency
commit;
select * from test1
order by val asc;
-- will give symbols in order: dollar('\0024'), pound ('\00a3'), yen ('\00a5')
I will say that I would not resort to using the national characterset, I would probably change the db characterset to fit the needs of my data, as supporting 2 diff character sets isn't ideal, but its available anyway
If you have no issues storing/retrieving on the data side, then your app/client characterset is probably different than your db.
Use nchar(168). It will work.
select nchar(168)
