I have a string with the value 'Initiator;abcd#gmail.com'.
I would like to read these two fields in two separate queries.
';' would be the delimiter always.
I used the below query and it works for fetching the email. However it looks overcomplicated to me.
select SUBSTRING(NOTES (CHARINDEX(';',NOTES,1)+1),LEN(NOTES))
from DOCUMENT
where DOC_ID = '12345'
Can someone please help in simplifying it and reading both the values.
Thanks in advance.
First, your query looks fine for email but it has incorrect syntax, second just use left() with charindex() to get the first part :
select left(notes, charindex(';', notes)-1),
substring(notes, charindex(';', notes)+1, len(notes))
from document
where doc_id = 12345;

I want to get record id by code in database. Problem is that many of codes in database are with line breaks or something else like:
"12545
"
I tried this queries, but it did not work, I only get ids that code has no line breaks
SELECT * FROM Firms WHERE REPLACE(Code,'/n/r','') = '302489977'
SELECT * FROM Firms WHERE TRIM(Code) = '302489977'
It's difficult without seeing what your data structure is like, but something like this may work. CHAR13 and CHAR10 represent line breaks.
Specifically, CHAR(13) is carriage return and CHAR(10) is line feed.
Select Replace(Replace(#str,CHAR(10),''),CHAR(13),'')
REPLACE(Code,CHAR(13)+CHAR(10),'')
maybe
Maybe you want to use LIKE?
SELECT * FROM Firms WHERE Code LIKE '%302489977%';
This will work if you can't have an id on multiple lines (that is to say on multiple lines) and if an other id can't be found in the code.
Hi all I am trying to write sql for selecting string between two special characters.
example: in the table, field value like 7185878969-129981041-000000 . how can I select only middle portion 129981041 without hard coding. What will be the best way to go about this?.Please provide sample code. Thanks
Impala has split_part():
select split_part(col, '-', 2)
Try this for MySQL:
SELECT REVERSE(SUBSTRING_INDEX(REVERSE(SUBSTRING_INDEX(Column,'-',2)),'-',1))
FROM table_name;
Result:
129981041
I'm attempting to modify one of my data values by concatenating a string to a date.
Below is what I've tried for my query but there seems to be some problem with my syntax.
Can someone point out what I'm doing wrong?
Try casting to a string first:
CONCAT(
CAST(created as nvarchar(max)),
' something else to concatenate'
)
If you hover over the query it will tell you what's wrong with the syntax.
Anyway, the problem it is likely to be that the created column is not a text format so it needs to be converted to a VARCHAR before being used by the CONCAT function. Try changing it to:
SELECT
CONCAT(CAST(created AS NVARCHAR(MAX)), ', XXX-YOUR-TEXT-XXX') AS NewName
[...]

Does anyone have a LIKE pattern that matches whole words only?
It needs to account for spaces, punctuation, and start/end of string as word boundaries.
I am not using SQL Full Text Search as that is not available. I don't think it would be necessary for a simple keyword search when LIKE should be able to do the trick. However if anyone has tested performance of Full Text Search against LIKE patterns, I would be interested to hear.
Edit:
I got it to this stage, but it does not match start/end of string as a word boundary.
where DealTitle like '%[^a-zA-Z]pit[^a-zA-Z]%'
I want this to match "pit" but not "spit" in a sentence or as a single word.
E.g. DealTitle might contain "a pit of despair" or "pit your wits" or "a pit" or "a pit." or "pit!" or just "pit".
Full text indexes is the answer.
The poor cousin alternative is
'.' + column + '.' LIKE '%[^a-z]pit[^a-z]%'
FYI unless you are using _CS collation, there is no need for a-zA-Z
you can just use below condition for whitespace delimiters:
(' '+YOUR_FIELD_NAME+' ') like '% doc %'
it works faster and better than other solutions. so in your case it works fine with "a pit of despair" or "pit your wits" or "a pit" or "a pit." or just "pit", but not works for "pit!".
I think the recommended patterns exclude words with do not have any character at the beginning or at the end. I would use the following additional criteria.
where DealTitle like '%[^a-z]pit[^a-z]%' OR
DealTitle like 'pit[^a-z]%' OR
DealTitle like '%[^a-z]pit'
I hope it helps you guys!
Surround your string with spaces and create a test column like this:
SELECT t.DealTitle
FROM yourtable t
CROSS APPLY (SELECT testDeal = ' ' + ISNULL(t.DealTitle,'') + ' ') fx1
WHERE fx1.testDeal LIKE '%[^a-z]pit[^a-z]%'
If you can use regexp operator in your SQL query..
For finding any combination of spaces, punctuation and start/end of string as word boundaries:
where DealTitle regexp '(^|[[:punct:]]|[[:space:]])pit([[:space:]]|[[:punct:]]|$)'
Another simple alternative:
WHERE DealTitle like '%[^a-z]pit[^a-z]%' OR
DealTitle like '[^a-z]pit[^a-z]%' OR
DealTitle like '%[^a-z]pit[^a-z]'
This is a good topic and I want to complement this to someone how needs to find some word in some string passing this as element of a query.
SELECT
ST.WORD, ND.TEXT_STRING
FROM
[ST_TABLE] ST
LEFT JOIN
[ND_TABLE] ND ON ND.TEXT_STRING LIKE '%[^a-z]' + ST.WORD + '[^a-z]%'
WHERE
ST.WORD = 'STACK_OVERFLOW' -- OPTIONAL
With this you can list all the incidences of the ST.WORD in the ND.TEXT_STRING and you can use the WHERE clausule to filter this using some word.
You could search for the entire string in SQL:
select * from YourTable where col1 like '%TheWord%'
Then you could filter the returned rows client site, adding the extra condition that it must be a whole word. For example, if it matches the regex:
\bTheWord\b
Another option is to use a CLR function, available in SQL Server 2005 and higher. That would allow you to search for the regex server-side. This MSDN artcile has the details of how to set up a dbo.RegexMatch function.
Try using charindex to find the match:
Select *
from table
where charindex( 'Whole word to be searched', columnname) > 0
Im using sql server 2005. i want data with comma. for example ['5000'],['5001'],..
but the last record should not include comma. Pls help me.
Query:
select '['''+convert(varchar,parcelid)+'''],' from sampletable
Try the COALESCE function
SELECT #groupedText = COALESCE(#groupedText, '') + [Text] + ','
FROM Requirement
WHERE CampaignId = #campaignId
ORDER BY [Text]
Then you could try one of the string functions to kill the end comma
T-SQL string functions
You can use regular expressions to remove the last comma or do it using your programming language (ASP etc. like a chop function or something).
http://weblogs.sqlteam.com/jeffs/archive/2007/04/27/SQL-2005-Regular-Expression-Replace.aspx
Consider using XML for this purpose. The "aggregate concatenation" solution may not be reliable, because it is not clearly documented and supported. You can get rid of the final comma with SUBSTRING, as boon suggested.
