I have this insert command where iam trying to insert a number to be taken from loop
i=0
for line in column:
myStmt.executeQuery("INSERT INTO REVERSE_COL
( TABLE_NAME,COL_NAME,POS) values
(,'test','"+column[i]+"','"+i+"'")
i=i+1
POS IS NUMBER DATATYPE
but it works if i hard code as 1
i=0
for line in column:
myStmt.executeQuery("INSERT INTO REVERSE_COL
( TABLE_NAME,COL_NAME,POS) values
(,'test','"+column[i]+"',1")
I have tried only i , +i+ and other method but its not working any suggestion how to solve this .
Thanks everyone .
I have no jython experience, but I will still try to offer my personal approach and advice. Take from it what you will.
The first thing that I would look into, and perhaps this is something someone else knows offhand, is the way that a number is concatenated to the string. I'm speaking from a C++ background here, but a number i may well be converted to the ASCII character representing that value, and not necessarily the character that you intend.
For example, if i is 9, it may be placing a TAB into the string and not the number 9, which would be an ASCII value 57.
Again, I'm not telling you this IS the answer...but it's the first thing that pops into my mind. Good luck!

I am currently facing a Regex problem which apparently I cannot find an answer to.
My Regex is embedded in a teradata SQL of the form:
REGEXP_SUBSTR(column, 'regex_pattern')
I want to find the first appearance of any number except if it appears at the end of the string.
For Example:
"YEL2X30" -> "2"
"YEL19XYZ05" -> "19"
"YELLOW05" -> ""
I tried it with '[0-9]+(?!$)/' but this returns me a blank String always.
Thanks in Advance!
Shot in the dark here since I'm unfamiliar with teradata and the supported SQL-functionality. However, reading the docs on the REGEXP_SUBSTR() function it seems like you may want to use the 3rd and 4th possible argument along with a slightly different regular expression:
[0-9]+(?![0-9]|$)
Meaning: 1+ Digits that are not followed by either the end of the string or another digit.
I'd believe the following syntax may work now to retrieve the 1st appearance of any number from the matching results:
REGEXP_SUBSTR(column, '[0-9]+(?![0-9]|$)', 1, 1)
The 3rd parameter states from which position in the source-string we need to start searching whereas the 4th will return the 1st match from any possible multiple matches (is how I read the docs). For example: abc123def456ghi789 whould return 123.
Fiddling around in online IDE's gave me that:
CREATE TABLE TBL (TST varchar(100));
INSERT INTO TBL values ('YEL2X30'), ('YEL19XYZ05'), ('YELLOW05'), ('abc123def456ghi789');
SELECT REGEXP_SUBSTR(TST, '[0-9]+(?![0-9]|$)', 1, 1) as 'RESULTS' FROM TBL;
Resulted in:
RESULTS
2
19
NULL
123
NOTE: I also noticed that leaving out the 3rd and 4th parameter made no difference since they will default back to 1 without explicitly mentioning them. I tested this over here.
Possibly the simplest way is to look for digits followed by a non-digit. Then keep all the digits:
regexp_substr(regexp_substr(column, '[0-9]+[^0-9]'), '[0-9]+')
I've got the following code in place with the idea being that I need a 30 character random number generated each time the stored procedure is called and the odd thing is that in most cases it works as intended but in other seemingly random cases it will only generate a 28 character random number.
'\\xxx-servername\folder\'+
CAST(CAST((RAND()*1000000000000000000000000000000) as decimal(30))as varchar(30)) +
RAM.AccountNumber+HRMRN.PrefixMedicalRecordNumber+'ESTIMATE N00001'+
REPLACE(CONVERT(VARCHAR(12),ISNULL(HRM.Birthdate,HRM.BirthdateComputed),111),'/','')+HRM.Sex+
REPLACE(CONVERT(VARCHAR(12),GetDate(),111),'/','')+LEFT(REPLACE(CONVERT(VARCHAR(12),GetDate(),108),':',''),4)+'.PDF' as [CPFileName]
Hope maybe someone can offer some advice because I'm at a loss...
I suspect that your system is automatically removing leading zeros. You can either re-insert those zeros yourself, or else construct your number using something like:
number <- ""
number.append(randomDigit(1,9))
repeat 29 times
number.append(randomDigit(0,9))
end repeat
That guarantees that you do not get a leading zero.
To start, I have seen the CHARINDEX results on here but none of them seem to be working for my case. The reasons are either a, CHARINDEX can't help me, or b, I am not understanding how CHARINDEX works. That being said, I would like to ask my question here in hopes that I can get some clarification on both how to solve my issue and CHARINDEX if that so happens to be the way this question is answered.
The variable that I am trying to extract from has varying length. However, two things are always constant.
There is always a '/' as the 16th character in the string
The last character in the string is always '0' OR '1'
What I am trying to do is extract the name from between '/' and '0' or '1'. In short, I want to chop off the first 16 characters and the last character of every string. So far, this is what I have:
SELECT
SUBSTRING([string_name], 17, LEN([string_name]) - 1) AS 'username'
FROM
[table_name]
The results I get still contain the 0 OR 1 at the end. What I need to do is somehow remove that 0 from the string. It is important to note that the number of characters between '/' and '0' are always different.
Current results:
gordon0
grant0
greg0
guy1
hanying0
Desired results:
gordon
grant
greg
guy
hanying
Any advice here would be wonderful.
Please let me know if you need any additional information from me. If possible, would like to maintain using either SUBSTRING, LEFT or RIGHT.
Thanks
Adjusting the length would seem to address your problem:
SELECT SUBSTRING([string_name], 17, LEN([string_name])-17) AS username
FROM [table_name]
I'm using system to control the process in my company and some of it has comment table, let us say it is Opr_comm. the content inside that attribute is various sometimes it contain "<", ">", "'" and so many symbols. here is the query.
SELECT
T1.Prod_No,
T1.Proc_CD,
T1.Opr_Comm
FROM
P110 T1
I have figure it out, when we input to system < it will turned to be <, when > it will be >. it happen when i retrieve it from database.
So, how can i convert that code to be symbol again?
Thank you very much for your help
If you're just looking to convert back to symbols when you are reading from the table, and not during the write process, you can use the REPLACE function
http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions134.htm
It's bulky, but if this is a limited issue it will work. You'd replace your code:
SELECT
T1.Prod_No,
T1.Proc_CD,
replace(replace(T1.Opr_Comm,"<","<"),">",">") AS Opr_Comm
From
P110 T1
Of course if you're able to prevent this encoding from happening in the first place, you'd be better off.
My task is to validate existing data in an MSSQL database. I've got some SQL experience, but not enough, apparently. We have a zip code field that must be either 5 or 9 digits (US zip). What we are finding in the zip field are embedded spaces and other oddities that will be prevented in the future. I've searched enough to find the references for LIKE that leave me with this "novice approach":
ZIP NOT LIKE '[0-9][0-9][0-9][0-9][0-9]'
AND ZIP NOT LIKE '[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
Is this really what I must code? Is there nothing similar to...?
ZIP NOT LIKE '[\d]{5}' AND ZIP NOT LIKE '[\d]{9}'
I will loath validating longer fields! I suppose, ultimately, both code sequences will be equally efficient (or should be).
Thanks for your help
Unfortunately, LIKE is not regex-compatible so nothing of the sort \d. Although, combining a length function with a numeric function may provide an acceptable result:
WHERE ISNUMERIC(ZIP) <> 1 OR LEN(ZIP) NOT IN(5,9)
I would however not recommend it because it ISNUMERIC will return 1 for a +, - or valid currency symbol. Especially the minus sign may be prevalent in the data set, so I'd still favor your "novice" approach.
Another approach is to use:
ZIP NOT LIKE '%[^0-9]%' OR LEN(ZIP) NOT IN(5,9)
which will find any row where zip does not contain any character that is not 0-9 (i.e only 0-9 allowed) where the length is not 5 or 9.
There are few ways you could achieve that.
You can replace [0-9] with _ like
ZIP NOT LIKE '_'
USE LEN() so it's like
LEN(ZIP) NOT IN(5,9)
You are looking for LENGTH()
select * from table WHERE length(ZIP)=5;
select * from table WHERE length(ZIP)=9;
To test for non-numeric values you can use ISNUMERIC():
WHERE ISNUMERIC(ZIP) <> 1
