Pretty simple one today. I've got a column, let's call it title, with a bunch of project titles. What I need to to pull everything from the left of the ":" and do a left/right trim (I'm then going to be using that in a join later on but I just need a column with the new data for now). So here's an example of what the current column looks like:
And here's what I need it to look like after the query is run:
The problem is while the # are 6 characters now, I can't guarantee they'll always be 6 characters. So if I was doing this in Excel I'd use the deliminated feature or just write a left/len/search function. Wondering how to do the same in SQL. BTW, I'm using SQL Server Management Studio.
Thoughts?
Assuming that your number is always followed by a [space]:[space], then simply look for that first space, and use its location as the argument for a left-substring operation:
SELECT LEFT(Title, CHARINDEX(' ', Title, 0)) AS "New Title"
p.s. Just say you're using MS SQL Server. SSMS is just a management front-end for that database.
check this post out. it does exactly what you are trying to do.

I'm trying to filter results from a Query i have created in Microsoft Query to pull data from a database into my Excel sheet. Specifically I'm trying to filter out based on the nth character of a string.
I can easily filter out the based on the first char:
SOPOrderReturnLine.ItemCode Like 'A25%'
But I have no idea how I could filter to show only entries where the 10th char = "A". I'm sure I have to use a Substring function, but it's not familiar to me and I'm struggling to get it to work.
Try to edit your sql query and enter the following statement:
select * from SOPOrderReturnLine where substring(SOPOrderReturnLine.ItemCode,10,1) = 'A';
The statement should work for a MySql database as well as for an Sql Server in the background; (I've tested it with an MySql database).
Hope this helps.
In MSQuery (Jet under the covers, I think), the function is Mid.
SELECT * FROM tblLocation WHERE (Mid(LocationName,2,1)='e')
to find a lower case 'e' in the second location.
I assume when you say MS Query, you are running a query against a DBMS (SQL Server or some other via ODBC).
The use of substr, substring or mid should work, depending on which DBMS. That said, unless you're using MS Access, I think most DBMSs will support the underscore character as "any single character." It might even work in Access, but I don't know for sure. Therefore, I think in addition to the suggestions you've gotten, this will also work in most cases:
SOPOrderReturnLine.ItemCode Like '_________A%'
If you want to use substring, don't hold me to these, but I think:
Oracle / DB2 / SQLite - substr
Microsoft SQL Server / Sybase / MySQL - substring
MS Access - mid
PostgreSQL -substr or substring
I have a requirement to do something I believe should be simple enough, but am not finding the right answer to. How do I use a checkmark as a column alias in SQL Server 2008 R2?
I've tried using Char(251) by setting it to a value and trying to assign the value as the column alias, but no joy on that one.
I've tried using Char(251) (and I know that's more of a square root mark, but not sure of the checkmark ascii value if there is one. I believe that is a unicode value?) directly but again no joy. This should be simple, but I'm simply not finding it.
Thanks.
You cannot use expressions as identifiers in SQL Server (or any other SQL database for that matter). You can, however, use Unicode characters in identifiers, so simply copy and paste the desired character:
select 'yes' as "☑︎";
or even
select 'blah' as "😀";
Having said that, you should not be doing all that -- presentation is not the task for a database engine; it should be implemented in the client application.
Consider below query containing both Persian(a right to left language) and English(a left to right language):
SELECT 'نرم افزار SQL سرور'
the required result is this string :
سرور SQL نرم افزار
Is there any function or any other way to converting string from ltr to rtl??
It is required to add N before string literal: SELECT N'نرم افزار SQL سرور'. This is needed to correctly interpret contained Unicode characters. (Source)
Important: In some cases, please avoid using standard copy-paste in order to put SELECT into SSMS command window. This could affect the RTL/LTR order. Instead, try to open correctly composed file using File > Open.
And regarding your comment:
the result should be : سرور SQL نرم افزار`
I admit I understand RTL writing system only partially, but from what I can see, Persian words are put to the output exactly in order as you entered them (even if reading right to left). Could you show me based on Unicode Bidirectional Algorithm or similar standards document why the word order should be changed by SQL Server? Shouldn't be change you expect made by preprocessing on another place, sending expected string form SELECT N'سرور SQL نرم افزار'? I see no point why just SQL SELECT should perform the change. If it did, what would happen if you feed result of such a SELECT into another SELECT? Another transformation? I have reasons to think that SQL server is interpreting your input technically correctly.
Hint: maybe you can try to surround your RTL text by different Directional formatting characters.
Please try the same SELECT with MySQL server at SQL Fiddle. Different server and technology, but the same result as Microsoft SQL Server gave.
Result from SSMS with MS SQL Server:
Conclusion: in order to get expected result, please form the input accordingly.
Related: Transformation of word order you expected can be done by appropriate settings in user interface.
When we add digit with english this will again not work following solution will work
SELECT nchar(8234)+ N' 33-M ' + N'کلینک کمرہ نمبر' +nchar(8236) + N'میں تشریف لائیں'
I have a table containing a nvarchar column [AffectedNodes] that looks something like this when you take a peek at its contents (two variations shown):
"MID128; MID129; MID130"
"[1,3,2]; [3,1,2]"
We are working on a change which will move the AffectedNodes into its own table [AffectedNode] that has a nvarchar column [NodeId], which should store one of the nodes from the above string. I'm tasked with migrating the existing content to the new format.
As you can see the values are split using semi-column and a space.
To follow the database upgrade process they use in our project I have to write an SQL query in SQL Server CE. I'm wondering how I could do this in a neat way. Thanks!
SQL CE supports, CHARINDEX and SUBSTRING function, did you check that out or did you see any issue with them?
is there a simple way to just output each record in a select statement to write to its own file?
for example, if you have the tsql query in sql server 2005,
select top 10 items, names + ':' + address from book
and you ended up with 10 text files with the individual name and addresses in each file.
is there a way to do this without writing an extensive spWriteStringToFile procedure? I'm hoping there is some kind of output setting or something in the select statement.
thanks in advance
SQL returns the result set first, there's no opportunity in there for writing records to specific files until afterwards.
Being SQL Server 2005, it's possible you could use a SQLCLR (.NET 2.0 code) function in a SQL statement without having to make a separate application.
In SSMS, you can do a results to file, but that wouldnt split each record out into its own file. I pretty sure you cannot do this out of the box, so it sounds like you will be rolling your own solution.
You'd do this in some client, be it Java, VBA or SSIS typically.
