I need to change the binary output to varchar(string), but it must same as to be the binary output. But while converting the binary(hex) value to varchar, empty set will be returned. Kindly help me.
E.x
If this is my binary value 0x24000000008B0100000000.
I need the same 0x24000000008B0100000000 output after converting it into string.
declare #val binary(20)
set #val=0x24000000008B0100000000
select #val, CONVERT(varchar(max),#val,1)
this also works for me :
SELECT CONVERT(VARCHAR(1000), varbinary_val, 1);
just change your value with varbinary_val
should work like:
DECLARE #a BINARY(20) = 0x24000000008B0100000000
SELECT CONVERT(varchar(max),#a,1), #a

I am trying to extract some characters from a string.
For Example in (316409953_ND_02142022_000001.pdf) I need the characters after the last underscore _ and before the "."
Answer: 000001
#test = 316409953_ND_02142022_000001.pdf
I have tried:
REVERSE(SUBSTRING(REVERSE(test),CHARINDEX('.',REVERSE(test))+1,CHARINDEX('_',REVERSE(test)+1)))
I need help with the last part of substring. First error I am getting is "Conversion failed when converting the varchar value 'fdp.100000_22024120_DN_359904613' to data type int."
Secondly I need it to pick only after the last "_"
Please guide or let me know if there's another way to do this.
This looks like SQL Server.
On that assumption, and using the single example value, you can try the follolwing:
declare #test varchar(50) = '316409953_ND_02142022_000001.pdf'
select #test OriginalValue,
ParseName(Right(#test, CharIndex('_',Reverse(#test))-1),2) ExtractedValue;
it isn't pretty but it does the job ;P
declare #str varchar(200) = '316409953_ND_02142022_000001.pdf'
declare #tempStr varchar(200)= (select SUBSTRING(#str,LEN(#str) + 2 - CHARINDEX('_',REVERSE(#str)),LEN(#str)))
set #tempStr = SUBSTRING(#tempStr,1,CHARINDEX('.',#tempStr) - 1)
select #tempStr
I want to do conversion in T-SQL from a varbinary type to string type
Here is an example :
First I got this varbinary
0x21232F297A57A5A743894A0E4A801FC3
And then I want to convert it to
21232f297a57a5a743894a0e4a801fc3
How to do this?
Try:
DECLARE #varbinaryField varbinary(max);
SET #varbinaryField = 0x21232F297A57A5A743894A0E4A801FC3;
SELECT CONVERT(varchar(max),#varbinaryField,2),
#varbinaryField
UPDATED:
For SQL Server 2008
I know this is an old question, but here is an alternative approach that I have found more useful in some situations. I believe the master.dbo.fn_varbintohexstr function has been available in SQL Server at least since SQL2K. Adding it here just for completeness. Some readers may also find it instructive to look at the source code of this function.
declare #source varbinary(max);
set #source = 0x21232F297A57A5A743894A0E4A801FC3;
select varbin_source = #source
,string_result = master.dbo.fn_varbintohexstr (#source)
If you want to convert a single VARBINARY value into VARCHAR (STRING) you can do by declaring a variable like this:
DECLARE #var VARBINARY(MAX)
SET #var = 0x21232F297A57A5A743894A0E4A801FC3
SELECT CAST(#var AS VARCHAR(MAX))
If you are trying to select from table column then you can do like this:
SELECT CAST(myBinaryCol AS VARCHAR(MAX))
FROM myTable
This works in both SQL 2005 and 2008:
declare #source varbinary(max);
set #source = 0x21232F297A57A5A743894A0E4A801FC3;
select cast('' as xml).value('xs:hexBinary(sql:variable("#source"))', 'varchar(max)');
I looked everywhere for an answer and finally this worked for me:
SELECT Lower(Substring(MASTER.dbo.Fn_varbintohexstr(0x21232F297A57A5A743894A0E4A801FC3), 3, 8000))
Outputs to (string):
21232f297a57a5a743894a0e4a801fc3
You can use it in your WHERE or JOIN conditions as well in case you want to compare/match varbinary records with strings
Here is a simple example I wrote to convert and convert back using the 2 convert methods, I also checked it with a fixed string
declare #VB1 VARBINARY(500),#VB2 VARBINARY(500),#VB3 VARBINARY(500)
declare #S1 VARCHAR(500)
SET #VB1=HASHBYTES('SHA1','Test')
SET #S1=CONVERT(varchar(500),#VB1,2)
SET #VB2=CONVERT(varbinary(500),#S1,2)
SET #VB3=CONVERT(varbinary(500),'640AB2BAE07BEDC4C163F679A746F7AB7FB5D1FA',2)
SELECT #VB1,#S1,#VB2,#VB3
IF #VB1=#VB2 PRINT 'They Match(2)'
IF #VB1=#VB3 PRINT 'They Match(3)'
PRINT str(Len(#VB1))
PRINT str(Len(#S1))
PRINT str(Len(#VB2))
SET #VB1=HASHBYTES('SHA1','Test')
SET #S1=CONVERT(varchar(500),#VB1,1)
SET #VB2=CONVERT(varbinary(500),#S1,1)
SELECT #VB1,#S1,#VB2
IF #VB1=#VB2 PRINT 'They Match(1)'
PRINT str(Len(#VB1))
PRINT str(Len(#S1))
PRINT str(Len(#VB2))
and the output

I need to convert a numeric value to nvarchar in sql command.
Can anyone please help me.
select convert(nvarchar(255), 4343)
Should do the trick.
declare #MyNumber int
set #MyNumber = 123
select 'My number is ' + CAST(#MyNumber as nvarchar(20))
declare #MyNumber float
set #MyNumber = 123.45
select 'My number is ' + CAST(#MyNumber as nvarchar(max))
If the culture of the result doesn't matters or we're only talking of integer values, CONVERT or CAST will be fine.
However, if the result must match a specific culture, FORMAT might be the function to go:
DECLARE #value DECIMAL(19,4) = 1505.5698
SELECT CONVERT(NVARCHAR, #value) --> 1505.5698
SELECT FORMAT(#value, 'N2', 'en-us') --> 1,505.57
SELECT FORMAT(#value, 'N2', 'de-de') --> 1.505,57
For more information on FORMAT see here.
Of course, formatting the result should be a matter of the UI layer of the software.
How to convert a column value from varbinary(max) to varchar in human-readable form?
The following expression worked for me:
SELECT CONVERT(VARCHAR(1000), varbinary_value, 2);
Here are more details on the choice of style (the third parameter).
"Converting a varbinary to a varchar" can mean different things.
If the varbinary is the binary representation of a string in SQL Server (for example returned by casting to varbinary directly or from the DecryptByPassPhrase or DECOMPRESS functions) you can just CAST it
declare #b varbinary(max)
set #b = 0x5468697320697320612074657374
select cast(#b as varchar(max)) /*Returns "This is a test"*/
This is the equivalent of using CONVERT with a style parameter of 0.
CONVERT(varchar(max), #b, 0)
Other style parameters are available with CONVERT for different requirements as noted in other answers.
Actually the best answer is
SELECT CONVERT(VARCHAR(1000), varbinary_value, 1);
using "2" cuts off the "0x" at the start of the varbinary.
Try this
SELECT CONVERT(varchar(5000), yourvarbincolumn, 0)
I tried this, it worked for me:
declare #b2 VARBINARY(MAX)
set #b2 = 0x54006800690073002000690073002000610020007400650073007400
SELECT CONVERT(nVARCHAR(1000), #b2, 0);
For a VARBINARY(MAX) column, I had to use NVARCHAR(MAX):
cast(Content as nvarchar(max))
Or
CONVERT(NVARCHAR(MAX), Content, 0)
VARCHAR(MAX) didn't show the entire value
Have a go at the below as I was struggling to
bcp "SELECT CAST(BINARYCOL AS VARCHAR(MAX)) FROM OLTP_TABLE WHERE ID=123123 AND COMPANYID=123"
queryout "C:\Users\USER\Documents\ps_scripts\res.txt" -c -S myserver.db.com -U admin -P password
Reference: original post
I know it could be done trivially in a non-SQL environment [post-data processing, frontend, what have you], but that's not possible at the moment. Is there a way to take a decimal(5,2) and convert it to a varchar without the trailing zeroes/decimal points? For example:
declare #number decimal(5,2)
set #number = 123.00
select cast(#number as varchar) as FormattedNumber
And the result is '123.00'. Is there a (simple) way to get '123' instead? And likewise, instead of '123.30', '123.3'? Could do it by figuring out whether or not the hundredths/tenths places were 0 and manually trimming characters, but I wanted to know if there was a more elegant solution.
What about:
SELECT CAST(CAST(#number AS float) AS varchar(10))
However you may want to test this carefully with your raw data first.
This way is pretty simple:
DECLARE #Number DECIMAL(5,2)
SELECT #Number = 123.65
SELECT FormattedNumber = CAST(CAST(#Number AS DECIMAL(3,0)) AS VARCHAR(4))
Returns '124'.
The only thing to consider is whether you want to round up/down, or just strip the zeroes and decimal points without rounding; you'd cast the DECIMAL as an INT in the second case.
For controlled formatting of numbers in T-SQL you should use the FORMAT() function. For example:
DECLARE #number DECIMAL(9,2); SET #number = 1234567.12;
DECLARE #formatted VARCHAR(MAX); SET #formatted = FORMAT(#number, 'N0', 'en-AU');
PRINT #formatted;
The result will be:
1,234,567
The arguments to the FORMAT() function are:
FORMAT(value, format [, culture])
The value argument is your number. The format argument is a CLR type formatting string (in this example, I specified "normal number, zero precision"). The optional culture argument allows you to override the server culture setting to format the number as per a desired culture.
See also the MSDN ref page for FORMAT().
The Convert function may do what you want to do.
ms-help://MS.SQLCC.v9/MS.SQLSVR.v9.en/tsqlref9/html/a87d0850-c670-4720-9ad5-6f5a22343ea8.htm
Let me try this again....
CREATE FUNCTION saneDecimal(#input decimal(5,2)) returns varchar(10)
AS
BEGIN
DECLARE #output varchar(10)
SET #output = CAST(#input AS varchar(10))
DECLARE #trimmable table (trimval char(1))
INSERT #trimmable VALUES ('0')
INSERT #trimmable VALUES ('.')
WHILE EXISTS (SELECT * FROM #trimmable WHERE trimval = CAST(SUBSTRING(#output, LEN(#output), 1) AS char(1)))
SET #output = LEFT(#output, LEN(#output) - 1)
RETURN #output
END
GO
SELECT dbo.saneDecimal(1.00)
You could strip the trailing zeroes in a while loop:
declare #number decimal(5,2)
declare #str varchar(100)
set #number = 123.00
set #str = #number
while substring(#str,len(#str),1) in ('0','.',',')
set #str = substring(#str,1,len(#str)-1)
But as AdaTheDev commented, this is more easily done client-side.
Simple and elegant? Not so much...but that's T-SQL for you:
DECLARE #number decimal(5,2) = 123.00
DECLARE #formatted varchar(5) = CAST(#number as varchar)
SELECT
LEFT(
#formatted,
LEN(#formatted)
- PATINDEX('%[^0.]%', REVERSE(#formatted))
+ 1
)
Use the Format(value,format string,culture) function in SQL Server 2012+
If you have SQL Server 2012 or Greater you can use the format function like this:
select format(#number,'0') as FormattedNumber
Of course the format function will return an nvarchar, and not a varchar. You can cast to get a specific type.
Also, take a look at the T-SQL STR function in Books Online; this can be used for formatting floats and might work for your case. For some reason it doesn't come up in Google searches relating to this problem.
