Problem About Caculating Wide-char Strings' Character Count
Jan 8, 2008
it's like this, i have a temporary table such as
create table temp_table (str varchar(50))
and i have a data table
create table data_table (str varchar(20))
now i import my data(in which there is some corrupted lines) into the temporary table, they should be all ansi-character strings and no more than 20 characters, but now some wrong datas in which there are wide-characters are mixed in. as the result of these wide-characters, the corrupted strings each takes over 20 bytes, but i can't filter them out, as when i enter in "len(str)", the sql server returns character counts, instead of byte counts, i thought this should only happen when i was using a unicode date type!(e.g. nvarchar). but now the server also behaves like this on those ansi date types. it seems all string manipulating functions refering string length behaves like this.
so when i am trying to run:
insert into data_table select str from temp_table where len(str) <= 20
or
insert into data_table select left(str,20) from temp_table
it will always end up with a string truncating error
String or binary data would be truncated. The statement has been terminated
So now my problem is how to get the count of byte, but character, of a string containing wide-characters?
i'm using sql server 2005 standard version with sp2
Replace Char At End Of String
Mar 2, 2000Hi,
I have a table where this one column(varchar) has rows of data with a period at the end of the string. Is there any function I could use to remove all the periods?
For eg:
bhjio.
shtpl.
should become:
bhjio
shtpl

Search Char In String
Jan 11, 2006Hi
Is there any function to seperate a sting (VARCHAR) into two based on a character in the string (e.g. '-').
In short is there "InStr" or "split" type function in T-SQL ? If not what is the alternative?
I have a column called "Range" (VarChar) in the table which has ranges like 1-14 or 15-49 etc.
I need to select records by compare a variable (numeric) against these ranges.
So for instace if the variable has 15 its in range 15-49.
I was thinking of spliting the range field into two so that comparison is possible.
Any suggestions?
thanks
How To Compare Nvarchar(15), Char(5), And String
Jan 31, 2008I have used a query statement with the following WHERE string to 'Fill' a dataset.
"AND (A.ApptsDate > '" & strApptPreDate & "' OR (A.ApptsDate = '" & strApptPreDate & "' AND A.ApptsTime >= '" & strApptPreTime & "' ))" & _ and strApptPreTime is defined as:Dim strApptPreTime As String = SomaShared.strPadTime(CStr(dApptCalcNewDate.Hour) + ":" + CStr(dApptCalcNewDate.Minute))
Somehow, the dataset showed only the ApptsTime after 10 am. After more than 2 weeks of debugging, I still can see a dataset watch for > 10 amAppsTime only. Now I am guessting, the problem is 9 is different from 10 - 16, it all because 9 is single digit. Then I check the data type settings for these variables. Here are what I found:
In SQL Server Agent job, the ApptsTime data was 'inserted' by @NewApptTimes, which is declared as char(5).In SQL Server database, the ApptsTime was defined as nvarchar(15).
My question are: 1. The reason why there were no 9 am data for the dataset, is becasue 9 am of nvarchar(15) is not > 8:30 of strApptPreTime? 2. If the answer to the quation 1 is yes, how do I define AppsTime and/or strApptPreTime?
TIA,Jeffrey

View 5 Replies View RelatedTurn Hex Into Char String And Concatenate
Feb 16, 2006I've been trying to return hex data in a way that can be concatenated.
I need the actual hex info (e.g. 0x6E3C070) as displayed
since it contains info about the path to a file.
So I can turn it into D:6E3C 7 to get the path to the file.
In searching around I have come across a way to do this but can't figure out how to get it to run through a column and either display or insert into a table multiple results.
-Here's the user function that converts an integer into a hex string-
CREATE FUNCTION udf_hex_string (@i int)
RETURNS varchar(30) AS
BEGIN
DECLARE @vb varbinary(8)
SET @vb = CONVERT(varbinary(8),@i)
DECLARE @hx varchar(30)
EXEC master..xp_varbintohexstr @vb, @hx OUT
RETURN @hx
END
GO
-Using this table-
create table
XPages
(PageStoreId int null,
HexString varchar (30) null,
VolumePath varchar (60) null, )
--'PageStoreId' contains the data that needs to be converted into the editable hex string
--'HexString' is where I'd like it to go so I can parse it later.
--I can run the below select and get the hex string. But am stuck on how to run a select or update that would run through the 'XPages.PagestoreId'
column and insert the hex string into the 'XPages.Hexstring' column. 'XPages.PagestoreId' could have 100's of entries that need to be converted and placed in the relevant the 'XPages.Hexstring' column.

i woder if someone know Built in function to search the occurence of char in string in T-SQL
and iam not talking about the Index of the first occurence (e.g CHARINDEX )
but it is more generic
i want to send to the function to ask about the index the second or the third or N occurence of the char.

What Is The Difference Between Updating Null Value Vs Empty String To Varchar/char Field?
Aug 29, 2007Hi,
What is the difference updating a null value to char/varchar type column
versus empty string to char/varchar type column?Which is the best to do and why?
Could anyone explain about this?
Example:
Table 1 : tCountry - Name varchar(80) nullable
Table 2 :tState - Name char(2) nullable
Table 3 :tCountryDetails - countryid,state (char(2) nullable) - May the country contain state or no state
So,when the state is not present for the country ,i have two options may be - null,''
tCountryDetails.State = '' or tCountryDetails.State = null?

You can see the "9" on top of the data, for example:Slot 0, Offset 0x60, Length 9, DumpStyle BYTE
or calculate from the offset array
