I have my sql database where i would like to filter out all the valid mobile numbers.
I currently use as follows;
WHERE pn.PhoneNumber LIKE '+[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
OR pn.PhoneNumber LIKE '[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
OR pn.PhoneNumber LIKE '[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
OR pn.PhoneNumber LIKE '[0-9][0-9][0-9]-[0-9][0-9][0-9][0-9][0-9][0-9]'
However I still receive numbers such as 0000000, 0 ,0000 etc.
Some of the numbers aren't Irish mobiles either as they don't begin with 08.
To fix there if I wanted the beginning of the number to begin with an 087 would I just input [0][8][7] instead of the [0-9]?
try testing this !
this'll give numbers starting with 087 and mobile(length)=10
select * from table where mobile_number like '087%' and LEN(mobile_number)=10

I would create a table containing all the prefixes that I was interested in and then use that to do the validation.
Something like ....
Create table Allowed ( Prefix VARCHAR(10) )
insert into allowed values ( '071' );
insert into allowed values ( '072' );
insert into allowed values ( '+44' );
select count(prefix) as OK
from allowed
where REPLACE( pn.phonenumber, ' ', '') like prefix || '%'
You can still do the numeric validation separately, or combine the regexp part into the suffix added above.
I know this is out of date but just developed code for a UK Mobile Number that someone might find useful. It checks with or without a space, hyphen etc after the first 5 numbers and returns a blank if the number isn't valid - I need to upload records to a third party who reject records with invalid mobile numbers but accept blanks.
Mobile = CASE WHEN MobileTel LIKE '07[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]%' THEN left(MobileTel,11) WHEN MobileTel LIKE '07[0-9][0-9][0-9][^0-9][0-9][0-9][0-9][0-9][0-9][0-9]%' THEN (LEFT(MobileTel,5)+substring(MobileTel,7,6)) ELSE '' END

I'll try and make this clear...
Let's say I have a table with 2 columns. issue_number and issue_text. I need to grab 2 strings out of the issue_text column. The first string is something that can be hard coded with case statements since there are only so many types of issues that can be logged (note, i know this isn't the best way)
case
when issue_text like '%error%' then 'error'
else 'not found'
end as error_type
the issue_text is a string that will be formatted mostly the same, it'll have an error, more info, then an incident number, and that is the end of the string.
i.e. "Can't add address. Ref Number: 9999999"
the problem I'm having is the number will not always be the same amount of characters away from the error message.
I was wondering if there is a way to access the substring that causes a match from the like clause. like another case statement using a regex(which i know aren't supported well in sql)
case
when issue_text like '%[0-9 .]%' then (the substring match from like '%[0-9 .]%')
else 00000
end as issue_number
I am restricted to solving this issue and parsing these strings from SQL Server Management Studio or yes, I'd use .net or something to leverage.
Declare #YourTable table (ID int,issue_text varchar(150))
Insert Into #YourTable values
(1,'Can''t add address. Ref Number: 9999999'),
(2,'error')
Select ID
,Issue = Left(issue_text,PatIndex('%:%',issue_text+':')-1)
,IssueNo = substring(issue_text,PatIndex('%:%',issue_text+':')+2,25)
From #YourTable
Returns
ID Issue IssueNo
1 Can't add address. Ref Number 9999999
2 error
If there's always a space just before the number and the number is the last part of the string you can do
RIGHT(issue_text, CHARINDEX(' ', REVERSE(issue_text)) - 1)
I have a requirement to pull data in a specific format and I'm struggling slightly with the ROWTOCOL function and was hoping a fresh pair of eyes might be able to help.
I'm using 10g Oracle DB (10.2) so LISTAGG which appears to do what I need to achieve is not an option.
I need to aggregate a number of usernames into a string delimited with a '$' but I also need to concatenate another column to to build up email addresses.
select
rowtocol('select username_id from username where user_id = '||s.user_id|| 'order by USERNAME_ID asc','#'||d.domain_name||'$')
from username s, domain d
where s.user_id = d.user_id
(I've simplified the query specific to just this function as the actual query is quite large and all works except for this particular function.)
in the DOMAIN Table I have a number of domains such as 'hotmail.com','gmail.com' etc
I need to concatenate the username, an '#' symbol followed by the domain and all delimited with a '$'
such as ......
joe.bloggs#gmail.com$joeblogs#gmail.com$joe_bloggs#gmail.com
I've battled with this and I've got close but in reverse?!.....
gmail.com$joe.bloggs#gmail.com$joeblogs#gmail.com$joe_bloggs
I've also noticed that if I play around with the delimiter (,'#'||d.domain_name||'$') it has a tendency to drop off the first character as can be seen above the preceding '#' has been dropped from the first email address.
Can anyone offer any suggestions as to how to get this working?
Many Thanks in advance!
Assuming you're using the rowtocol function from OTN, and have tables something like:
create table username (user_id number, username_id varchar2(20));
create table domain (user_id number, domain_name varchar2(20));
insert into username values (1, 'joe.bloggs');
insert into username values (1, 'joebloggs');
insert into username values (1, 'joe_bloggs');
insert into domain values (1, 'gmail.com');
Then your original query gets three rows back:
gmail.com$joe.bloggs
gmail.com$joe_bloggs#gmail.com$joebloggs
gmail.com$joe_bloggs#gmail.com$joebloggs
You're passing the data from each of your user IDs to a separate call to rowtocol, which isn't really what you want. You can get the result I think you're after by reversing it; pass the main query that joins the two tables as the select argument to the function, and have that passed query do the username/domain concatenation - that is a separate step to the string aggregation:
select
rowtocol('select s.username_id || ''#'' || d.domain_name from username s join domain d on d.user_id = s.user_id', '$')
from dual;
which gets a single result:
joe.bloggs#gmail.com$joe_bloggs#gmail.com$joebloggs#gmail.com
Whether that fits into your larger query, which you haven't shown, is a separate question. You might need to correlate it with the rest of your query.
There are other ways to string aggregation in Oracle, but this function is one way, and you already have it installed. I'd look at alternatives though, such as ThomasG's answer, which make it a bit clearer what's going on I think.
As Alex told you in comments, this ROWTOCOL isn't a standard function so if you don't show its code, there's nothing we can do to fix it.
However you can accomplish what you want in Oracle 10 using the XMLAGG built-in function.
try this :
SELECT
rtrim (xmlagg (xmlelement (e, s.user_id || '#' || d.domain_name || '$')).extract ('//text()'), '$') whatever
FROM username s
INNER JOIN domain d ON s.user_id = d.user_id
I have a table (defect ) where a column stores a text. Each line in this text represents a version. (this is clearquest database running microsoft SQL, accessed via JDBC)
For example, following data represents three versions a fix is made.
defect version_fixed
1 2015.1.1
2 2015.1.1\n2015.1.13
3 2015.1.12\n2015.1.1
4 2015.1.12\n2015.1.1\n2015.1.13
5 2015.1.13\n2015.1.10
5 2015.1.100
As you see the version is not stored in an order. It can appear anywhere.
I am interested in all rows with fix version fixed containing "2015.1.1". But my query either gets more rows or skips some
version_fixed like '%2016.1.1%' (gets row 5 as it matches the pattern)
version_fixed like '%2016.1.1\n'(does not get any thing.)
I am looking for query to get exact list for 2015.1.1
defect version_fixed
1 2015.1.1
2 2015.1.1\n2015.1.13
3 2015.1.12\n2015.1.1
4 2015.1.12\n2015.1.1\n2015.1.13
How can I query where text matches with "exact string, delimited by new line or end of text". What is the correct way to escape new line?
Side note: Current solution is to get all records(including unwanted one and then filter out incorrect results)
You could try this. It relies on Sql Server adding the newline to the string when you break the line.
create table defect( version_fixed varchar(max) )
insert into defect( version_fixed )
values ( '2015.1.1' )
, ( '2015.1.1
2015.1.13' )
, ( '2015.1.12
2015.1.1' )
, ( '2015.1.12
2015.1.1
2015.1.13')
, ( '2015.1.13
2015.1.10' )
, ( '2015.1.100' )
-- break to a new line and Sql Server will include the newline character in the string
select * from defect where version_fixed like '%2015.1.1
%' or version_fixed like '%2015.1.1'
You can as the below:
WHERE '\' + version_fixed + '\' LIKE '%2015.1.1\%'
This solution depands on your sample data.
The Data
Let us say I have a field in SQL that consists of multi-line Information, each of which consists of i topics, each topic consisting of m points of information. Topics are prefaced with 'i.' and information with a dash. It looks something like:
________________________________________________
|Number | Information
|===============================================
|1 | 1. Topic 1.1
| | -Info 1.1.1
| | - ... [more info]
| | 2. Topic 1.2
| | -Info 1.2.1
| | - ...[more info]
| | ... [more topics]
|_______|_____________________________
|2 | 1. Topic 2.1
|....and so on
The Current System
What I am doing with this information is to parse out each topic into it's own column, then unpivoting those columns and searching for Topics that contain a given keyword #keyword.
Currently the code reads something like:
Select
Number
,Case When Information LIKE '%1. %2. %'
Then substring (Information, charindex('1.',Information),
charindex('2.', Information) -(charindex('1.',Information)+2) )
Else Information
End as [Topic1]
,Case When Information LIKE '%2. %3. %'
Then substring (Information, charindex('2.',Information),
charindex('3.', Information) -(charindex('2.',Information)+2) )
Else 'N/A'
End as [Topic2]
...repeat 2nd case for each set of numbers up to '%20. %21. %'
The only reason the first one is different is because if it doesn't match the pattern then I want to grab the whole field so that I don't miss anything. I then unpivot the Topic fields that I just created into a general [Topic] field, and then utilize a WHERE [Topic] LIKE '%' +#keyword+'%' to pull out any particular topics and their associated case number to output as my final table. The cases can have anywhere from 1 to 40+ topics attached, with 1-7 attached info fields per topic.
The Desired Modification
Notice: To make the code easier to read, I will not be writing my substring code in proper syntax, instead opting to write substring(Information,ci(#Iter), ci(#Iter+1)-ci(#Iter)) to denote the substring running from the position given by '(iter).' to the position given by '(iter+1).'
What I would like to do is to perform the following:
Declare #Iter smallint
Declare #Result varchar(max)
Select
Number
, Set #Iter=1
Set #Result = ' '
Case When Information LIKE '%'+#keyword+'%' --keyword chosen at front end
Then While #Iter < #n --#n set by the user from front end
Begin
Case When Information LIKE '%' + cast(#Iter as varchar(5))
+ '. %'+cast((#Iter+1) as varchar(5))+'. %'
and substring(Information,ci(#Iter), ci(#Iter+1)-ci(#Iter) )
LIKE '%'+#keyword+'%'
Then Set #Result = #Result +substring(Information,ci(#Iter),
ci(#Iter+1)-ci(#Iter) )
Else Set #Result = #Result end
Set #Iter = #Iter +1
End
Else ' ' end [Result]
The Explanation
In case what I want isn't clear, I'll run through what I'm trying to accomplish
I want to output a list of case numbers that include Topics that include the keyword.
For each case in the list I want to output only those topics that include the keyword.
I want to allow the end user of the report to choose how many Topics in each case they'll search.
I don't want to have to create a table with a column for each Topic when I can't know how many the user will want to create.
Due to these considerations it feels like a loop would be the best option, but there are problems in trying to accomplish that.
The Problem
SQL server won't allow me to utilize a loop in my Select statement--Incorrect syntax near 'While'.
The place where the information comes from prohibits normalization of the information in the table I'm searching
Even if it didn't I am barred from creating my own permanent tables at work, so I can't normalize the data for all incoming data
I am also not allowed to write my own stored procedures.
If there is any way (for example through a cte) to implement these changes, I'm open to hearing them! I'm mostly looking at ways to make the code less daunting looking (20 cases to produce 20 fields in my current cte looks scary, which then needs 3 ctes just to unpack properly [unpivot, removal of certain cases meeting certain conditions, combination into a workable output table])
Thanks in advance for reading this and helping!
I think you're working too hard.
If all you need are topic names and numbers, isn't it easier to split the Information column by newlines, and then collect all lines that start with a number and not a "dash" by then, you will have a list of strings that look like:
Topic 1.1
Topic 2.1
And then it's easy to just match the lines against the keyword?
Something like this untested SQL:
select SUBSTRING(s.value,1, PATINDEX('% %', s.Value) - 1) AS topicId
, SUBSTRING(s.Value, PATINDEX('% %', s.Value), LENGTH(s.Value)) AS topicText
from [table that would make Codd cry] t
cross apply STRING_SPLIT(t.Information, CHAR(13)) s
where s.Value LIKE '[0-9]%' -- Starts with a number
AND s.Value LIKE #keywords --matches keywords
Not sure if you can create functions or you have STRING_SPLIT available in your SQL Server version, but if you don't, there are some string splitting CTEs you can find on the net to do the job for you
I have an interesting SQL Server search requirement.
Say I have a table with Part Numbers as follows:
PARTNO DESCRIPTION
------ -----------
ABC-123 First part
D/12a92 Second Part
How can I create a search that will return results if I search, say, for 'D12A'?
I currently have a full text search set up for the description column, but I am looking to find parts that match the part no even when users don't include the / or - etc.
I'd rather do this in a single SQL statement rather than creating functions if possible as we only have read access to the DB.
You could do something like:
SELECT * FROM PART_TABLE
WHERE REPLACE(REPLACE(PARTNO,'/', ''),'-','') LIKE '%D12A%'
This would work for the 2 characters you specified and could be extended for more character like so:
SELECT * FROM PART_TABLE
WHERE REPLACE(REPLACE(REPLACE(PARTNO,'/', ''),'-',''),*,'') LIKE '%D12A%'
Probably not the most elegant of solutions unless your special characters are limited. Otherwise I'd suggest writing a Function to strip out non-alphanumeric characters.
Here is an example of such a function:
CREATE FUNCTION dbo.udf_AlphaNumericChars
(
#String VARCHAR(MAX)
)
RETURNS VARCHAR(MAX)
AS
BEGIN
DECLARE #RemovingCharIndex INT
SET #RemovingCharIndex = PATINDEX('%[^0-9A-Za-z]%',#String)
WHILE #RemovingCharIndex > 0
BEGIN
SET #String = STUFF(#String,#RemovingCharIndex,1,'')
#RemovingCharIndex = PATINDEX('%[^0-9A-Za-z]%',#String)
END
RETURN #String
END
------- Query Sample (untested)---------
SELECT *
FROM PART_TABLE
WHERE DBO.udf_AlphaNumericChars(PARTNO) LIKE '%D12A%'
