Rtrim And Ltrim?

Oct 5, 2004

I have some data that contains spaces both before and after the text string, and now I'm wondering what would be the best method to remove these blanks (sometimes there are no blanks, so I can't check with a specifik width)?

Is it possible to do something like:

set foo = ltrim(rtrim(foo))

or do I have to split it into 2 steps?

This trimming will be done in update & insert statements

&<Long Text&> Doesn't Show Up

Mar 21, 2006

I have a question that has a co-worker and myself confused. We are using the SQL Server Enterprise Manager. When I select return all rows in my tables, any content that is too long will appear as <Long Text> on my co-workers machine, but the column is blank on my machine. Is there a property or configuration that enables/disables <Long Text>? I am confused as to why it appears on other machines, but not mine.

Your help is appreciated.

(long) Querry Doesn't Fit In Query-string Window

Jun 4, 2007

hi,

i have worked three days on a query to display all my results in a beautiful report. The query is fine because when i execute it in Query Analyzer i have all results i want to see in my statistics-table in my report...

One thing: it's contains about 100 unioned statements, which results in a super-long query. Performance is OK because it are all 100 very easy statements that are union-ed together.

But, when I copy-paste it in my query-string window/textbox of the report designer, I see that there's a maximum on that textbox lenght, which results in the fact that my long query suddenly stops.

Any solutions????

SQL Server 2008 :: Using String Functions On Text

This text value has some special characters in it. and I could not paste the exact value as this text box is not allowing me to do so. So, for reference I've attached a screenshot (Capture.png) of the value.

I want to fetch last two values from this text i.e. 25 and 06. (It can be anything like 56R,06T but will be the last two values separated by comma)...

Can You Parse Out A Text String &> 8000 Chars Long??

Mar 30, 2005

Any way to parse out a text value (not varChar, using text data type) that is > than 8000 characters long? I'm looping through 1 big string passed to the DB that is pipe delimited, but I find myself needing the substring function to keep track of which segment I'm acting on (after an update, I then need to take that segment and remove it from the string)...but the subString function won't take anything larger than 8000 chars.

Say I have this string that is text data type...

'aaa|bbb|ccc|ddd|....'

..and so on, surpassing 8000 char length, how could you parse it out using the pipes as the delimter, then do an Update using that segment? Afterward, return to that string and find the next segment, then use it, and so on (in a loop). I tried using an update to set the string = replace(string, segmentJustUsed, '') to "erase" it, but replace can't take text as the datatype. Any help? Hope this isn't to confusing.

Problem With Text Field: Text Input Too Long, Weird Characters

May 15, 2006

Hi,

Im a programmer for an university webportal which uses php and msssql.
When an user creates a new entry and his text is too long the entry is cut short and weird characters appear at the end of the entry.

For example:
http://www.ttz.uni-magdeburg.de/scripts/test-messedb/php/index.php?option=show_presse&funktion=presse_show_mitteilung&id=333

How can I set the text limit to unlimited?
Could it be something else?
Is there a way of splitting an entry to several text fields automatically?


Thanks in advance for any help you can give me,

Please Comment.

You should use readtext and writetext to access text column. By the way, nchar and nvarchar can hold up to 4000 characteres.
