SQL Server 2012: check if is uniqueidentifier and convert to string

SQL Server 2012: check if is uniqueidentifier and convert to string - tsql

I am trying to test if a variable is a uniqueidentifier and if it is then convert it to string but it fails:
Declare #Item VARCHAR(50)
Declare #OutString varchar(max) ;
--#Outstring is populated from various tables each cell separated by ','
--Getting the #Item from the #Outstring and convert it if its uid
DECLARE #Pos INT
DECLARE #Loop BIT
SELECT #Loop = CASE WHEN LEN(#OutString) > 0 THEN 1 ELSE 0 END
WHILE (SELECT #Loop) = 1
BEGIN
SELECT #Pos = CHARINDEX(',', #OutString, 1)
IF #Pos > 0
BEGIN
SELECT #Item = SUBSTRING(#OutString, 1, #Pos - 1)
SELECT #OutString = SUBSTRING(#OutString, #Pos + 1, LEN(#OutString) - #Pos)
IF (TRY_CONVERT(UNIQUEIDENTIFIER, #Item) IS NOT NULL)
BEGIN
CONVERT(NVARCHAR(50), #Item) AS #Item --ERROR LINE incorrect syntax
END
END
END

it is either
select #Item = convert(nvarchar(50), #Item)
or
select #Item = cast(#Item as nvarchar(50))

The syntax error is because you have said the action but not what SQL should do with it.
Do you want the string to be returned?
SELECT CONVERT(NVARCHAR(50), #Item) AS Item
Appended to #Item? (but this variable is inside your loop?)
SET #Item += CONVERT(NVARCHAR(50), #Item)
Not sure what you want to do once you have converted the string. Maybe you need another variable to add the string on (like above except not SET #Item)

Use
SELECT convert(nvarchar(50), #Item ) as Item

How to remove duplicate words from a string comparing to other string in SQL

I need to check string2 if there are words that I already have in string1 and remove those.
declare #Text1 nvarchar(500) = 'apple, orange, pear'
declare #Text2 nvarchar(500) = 'banana, apple'
The output should be 'banana'
Edit: I just realized I made the question not properly.
So, this is right:
DECLARE #Tab TABLE (Ingredients nvarchar(500))
insert #Tab select 'apple, orange, pear'
insert #Tab select 'banana, apple'
insert #Tab select 'pear, mango'
declare #Ingredients nvarchar(4000) = ''
select #Ingredients = #Ingredients + value + ',' from #Tab cross apply STRING_SPLIT(Ingredients, ',')
SELECT #Ingredients
current result:
apple,orange,pear,banana,apple,pear,mango,
expected result:
apple,orange,pear,banana,mango,

So if that is the case I would like to suggest you to create a function:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE FUNCTION GetUniqueValues
(
#LIST AS NVARCHAR(MAX)
)
RETURNS NVARCHAR(MAX)
AS
BEGIN
DECLARE #POS INT
DECLARE #LEN INT
DECLARE #VALUE NVARCHAR(MAX)
SET #POS = 0
SET #LEN = 0
DECLARE #RESULT NVARCHAR(MAX) = ''
WHILE CHARINDEX(',', #LIST, #POS + 1) > 0
BEGIN
SET #LEN = CHARINDEX(',', #LIST, #POS + 1) - #POS
SET #VALUE = RTRIM(LTRIM(SUBSTRING(#LIST, #POS, #LEN)))
IF (CHARINDEX(#VALUE, #RESULT) = 0)
BEGIN
IF (LEN(RTRIM(LTRIM(#RESULT))) = 0)
BEGIN
SET #RESULT = #VALUE
END
ELSE
BEGIN
SET #RESULT = #RESULT + ', ' + #VALUE
END
END
SET #POS = CHARINDEX(',', #LIST, #POS + #LEN) +1
END
RETURN #RESULT
END
GO
You can use this function like this based on you example:
SELECT dbo.GetUniqueValues(#Ingredients)
Expected result
apple, orange, pear, banana, mango

you can use something like this:
DECLARE #Text1 NVARCHAR(500)= 'apple, orange, pear';
DECLARE #Text2 NVARCHAR(500)= 'banana, apple, cucumber, pear';
--convert to xml for further split using nodes
declare #xmlText1 as xml = convert(xml, Concat('<a>',replace(#Text1,',','</a><a>'),'</a>'))
declare #xmlText2 as xml = convert(xml, Concat('<a>',replace(#Text2,',','</a><a>'),'</a>'))
--remove duplicates from #text2 that exist in #text1
;with cte (val) as (
select ', ' + value
from (
select ltrim(n.value('.', 'VARCHAR(10)')) AS value
from #xmlText2.nodes('a') as t(n)
except
select ltrim(n.value('.', 'VARCHAR(10)')) AS value
from #xmlText1.nodes('a') as t(n)
) as t
for xml path ('')
)
-- reassign #text2
select #Text2 = stuff(val,1,1,'') from cte
--output
select #Text2 as newText2
result

You can try this:
DECLARE #Text1 NVARCHAR(500)= 'apple, orange, pear';
DECLARE #Text2 NVARCHAR(500)= 'banana, apple';
SELECT *
INTO #temp
FROM
(
SELECT *
FROM fn_split(#Text1, ',')
) a;
SELECT *
INTO #temp1
FROM
(
SELECT *
FROM fn_split(#Text2, ',')
) b;
SELECT item
FROM #temp1 a
WHERE NOT EXISTS
(
SELECT item
FROM #temp b
WHERE a.item = b.item
);

TSQL Replace Doubled Characters

Let's say I have data:
heloo
cuube
triniity
How to write script that will replace those "doubled" characters with only one? So the result from the above data set would be:
helo
cube
trinity
Usually I post some script where I tried to achieve this, but this time I can't think of any.

This should work:
CREATE PROCEDURE remove_duplicate_characters(#string VARCHAR(100))
AS
DECLARE #result VARCHAR(100)
SET #result=''
SELECT #result=#result+MIN(SUBSTRING(#string ,number,1)) FROM
(
SELECT number FROM master..spt_values WHERE type='p' AND number BETWEEN 1 AND len(#string )) AS t GROUP BY SUBSTRING(#string,number,1) ORDER BY MIN(number)
)
SELECT #result
GO
You then call it like this:
EXEC remove_duplicate_characters 'heloo'
Source

This script does not depend on having access to master functions, and just relies on t-sql string functions.
declare #word varchar(100) = 'aaaacuuuuuubeeeee', #result varchar(100) = ''
declare #letter char, #idx int = 0, #lastletter char = ''
while(#idx <= len(#word))
begin
select #letter = substring(#word,#idx,1)
if (#letter != #lastletter)
begin
select #result = concat(#result,#letter)
end
select #lastletter = #letter,#idx = #idx + 1
end
select #result

Add comma every nth character in value

my problem is pretty simple. I get a value from a sql select which looks like this:
ARAMAUBEBABRBGCNDKDEEEFOFIFRGEGRIEISITJPYUCAKZKG
and I need it like this:
AR,AM,AU,BE,BA,BR,BG,CN,DK,DE,EE,FO,FI,FR,GE,GR,IE,IS,IT,JP,YU,CA,KZ,KG
The length is different in each dataset.
I tried it with format(), stuff() and so on but nothing brought me the result I need.
Thanks in advance

gbn's comment is exactly right, if not very diplomatic :) TSQL is a poor language for string manipulation, but if you write a CLR function to do this then you will have the best of both worlds: .NET string functions called from pure TSQL.

I believe this is what QQping is looking for.

Is a T-SQL conditional TOP clause possible?

I want to dynamically use TOP or not sort of like this...
SELECT #SomeNumber CASE WHERE 0 THEN TOP 5 COLUMNNAME
ELSE COLUMNNAME
END
FROM TABLE

I hope to have understood your problem: you want to select the TOP 5 rows if you pass #SomeNumber = 0 else select all th etable rows
As a first straight implementation you can do something like that
declare #SomeNumber as int
set #SomeNumber = 5
-- set #SomeNumber = 1
SELECT TOP (SELECT #SomeNumber) COLUMNNAME FROM MYTABLE
you can change the parameter value in order to have how many rows you want
Otherwise i suggest you to implement a stored procedure (and maybe you already did that, otherwise you can follow the next steps in order to do it)
CREATE procedure [dbo].[TOPCLAUSE]
-- clause parameter
#SomeNumber as integer
AS
IF #SomeNumber = 0
BEGIN
SELECT TOP 5 COLUMNNAME FROM MYTABLE
END
ELSE
BEGIN
SELECT COLUMNNAME FROM MYTABLE
END
GO
Then you can call
exec [dbo].[TOPCLAUSE] 0
exec [dbo].[TOPCLAUSE] 1
I probably not answered your question but let me know if it helped you

I don't think you can.
You could either use dynamic SQL:
Declare #int int
set #int = 10
exec ('Select top ' + #int + ' * From Customers')
Or you could set rowcount
if (#someNumber != 0)
begin
set rowcount 5
end
select * From Customers
set rowcount 0

I've just used something like this:-
Declare #SQL nvarchar(max), #Params nvarchar(max)
set #Params = N''
Set #SQL = N'SELECT ' + Cast(#SomeNumber as varchar) + ' CASE WHERE 0 THEN TOP 5 COLUMNNAME
ELSE COLUMNNAME
END
FROM TABLE'
exec sp_executesql #SQL, #Params

Short answer is no, not the way you have it.
You can however use IF to test and run a different query:
IF (#SomeNumber = 0)
BEGIN
SELECT TOP 5 ColumnName FROM Table
END
ELSE
BEGIN
SELECT ColumnName FROM Table
END

Two options: conditional SQL or dynamic SQL.
(1) Conditional:
IF #SomeNumber = 0
SELECT TOP 5 COLUMNAME FROM TABLE
ELSE
SELECT COLUMNAME FROM TABLE
(2) Dynamic: build up the query in a varchar() and pass it to sp_execute

Another loophole: make use of subquery's with row_number function
DECLARE #DoTopJN AS bit
SET #DoTopJN = 0 -- or 1
SELECT X.Sequence
X.COLUMNA
--etc
FROM (SELECT ROW_NUMBER() OVER (ORDER BY Y.Code) AS Sequence
,Y.COLUMNA
,Y.COLUMNB
-- etc.
FROM Y) X
WHERE ((#DoTopJN = 0) OR (X.Sequence = 1))

I don't think this is possible because TOP is applied on not just a column but the whole row. You would have to create two different select statements and put them in a IF ELSE construct.

To correct SPE109's code:
DECLARE #SomeNumber INT = 0
DECLARE #SQL nvarchar(max), #Params nvarchar(max)
set #Params = N''
SELECT #SQL = N'SELECT ' + CASE WHEN #SomeNumber = 0 THEN '' ELSE 'TOP ' + CAST(#SomeNumber as varchar) END + ' COLUMNNAME FROM TABLE'
exec sp_executesql #SQL, #Params

String.Format like functionality in T-SQL?

I'm looking for a built-in function/extended function in T-SQL for string manipulation similar to the String.Format method in .NET.

If you are using SQL Server 2012 and above, you can use FORMATMESSAGE. eg.
DECLARE #s NVARCHAR(50) = 'World';
DECLARE #d INT = 123;
SELECT FORMATMESSAGE('Hello %s, %d', #s, #d)
-- RETURNS 'Hello World, 123'
More examples from MSDN: FORMATMESSAGE
SELECT FORMATMESSAGE('Signed int %i, %d %i, %d, %+i, %+d, %+i, %+d', 5, -5, 50, -50, -11, -11, 11, 11);
SELECT FORMATMESSAGE('Signed int with leading zero %020i', 5);
SELECT FORMATMESSAGE('Signed int with leading zero 0 %020i', -55);
SELECT FORMATMESSAGE('Unsigned int %u, %u', 50, -50);
SELECT FORMATMESSAGE('Unsigned octal %o, %o', 50, -50);
SELECT FORMATMESSAGE('Unsigned hexadecimal %x, %X, %X, %X, %x', 11, 11, -11, 50, -50);
SELECT FORMATMESSAGE('Unsigned octal with prefix: %#o, %#o', 50, -50);
SELECT FORMATMESSAGE('Unsigned hexadecimal with prefix: %#x, %#X, %#X, %X, %x', 11, 11, -11, 50, -50);
SELECT FORMATMESSAGE('Hello %s!', 'TEST');
SELECT FORMATMESSAGE('Hello %20s!', 'TEST');
SELECT FORMATMESSAGE('Hello %-20s!', 'TEST');
SELECT FORMATMESSAGE('Hello %20s!', 'TEST');
NOTES:
Undocumented in 2012
Limited to 2044 characters
To escape the % sign, you need to double it.
If you are logging errors in extended events, calling FORMATMESSAGE comes up as a (harmless) error

take a look at xp_sprintf. example below.
DECLARE #ret_string varchar (255)
EXEC xp_sprintf #ret_string OUTPUT,
'INSERT INTO %s VALUES (%s, %s)', 'table1', '1', '2'
PRINT #ret_string
Result looks like this:
INSERT INTO table1 VALUES (1, 2)
Just found an issue with the max size (255 char limit) of the string with this so there is an alternative function you can use:
create function dbo.fnSprintf (#s varchar(MAX),
#params varchar(MAX), #separator char(1) = ',')
returns varchar(MAX)
as
begin
declare #p varchar(MAX)
declare #paramlen int
set #params = #params + #separator
set #paramlen = len(#params)
while not #params = ''
begin
set #p = left(#params+#separator, charindex(#separator, #params)-1)
set #s = STUFF(#s, charindex('%s', #s), 2, #p)
set #params = substring(#params, len(#p)+2, #paramlen)
end
return #s
end
To get the same result as above you call the function as follows:
print dbo.fnSprintf('INSERT INTO %s VALUES (%s, %s)', 'table1,1,2', default)

I have created a user defined function to mimic the string.format functionality.
You can use it.

This version allows the user to change the delimitter.

DECLARE #Message NVARCHAR(400)
DECLARE #ParamTable TABLE ( Id INT IDENTITY(0,1), Paramter VARCHAR(1000))
SELECT #Message = #Format
;WITH CTE (StartPos, EndPos) AS
(
SELECT 1, CHARINDEX(#Delimiter, #Parameters)
UNION ALL
SELECT EndPos + (LEN(#Delimiter)), CHARINDEX(#Delimiter, #Parameters, EndPos + (LEN(#Delimiter)))
FROM CTE
WHERE EndPos > 0
)
INSERT INTO #ParamTable ( Paramter )
SELECT
[Id] = SUBSTRING(#Parameters, StartPos, CASE WHEN EndPos > 0 THEN EndPos - StartPos ELSE 4000 END )
FROM CTE
UPDATE #ParamTable
SET
#Message = REPLACE(#Message, '{'+ CONVERT(VARCHAR, Id) + '}', Paramter )
RETURN #Message
END

There is a way, but it has its limitations. You can use the FORMATMESSAGE() function. It allows you to format a string using formatting similar to the printf() function in C.
However, the biggest limitation is that it will only work with messages in the sys.messages table. Here's an article about it: microsoft_library_ms186788
It's kind of a shame there isn't an easier way to do this, because there are times when you want to format a string/varchar in the database. Hopefully you are only looking to format a string in a standard way and can use the sys.messages table.
Coincidentally, you could also use the RAISERROR() function with a very low severity, the documentation for raiseerror even mentions doing this, but the results are only printed. So you wouldn't be able to do anything with the resulting value (from what I understand).
Good luck!

Raw t-sql is limited to CHARINDEX(), PATINDEX(), REPLACE(), and SUBSTRING() for string manipulation. But with sql server 2005 and later you can set up user defined functions that run in .Net, which means setting up a string.format() UDF shouldn't be too tough.

I think there is small correction while calculating end position.
Here is correct function

One more idea.
Although this is not a universal solution - it is simple and works, at least for me :)
For one placeholder {0}:
create function dbo.Format1
(
#String nvarchar(4000),
#Param0 sql_variant
)
returns nvarchar(4000)
as
begin
declare #Null nvarchar(4) = N'NULL';
return replace(#String, N'{0}', cast(isnull(#Param0, #Null) as nvarchar(4000)));
end
For two placeholders {0} and {1}:
create function dbo.Format2
(
#String nvarchar(4000),
#Param0 sql_variant,
#Param1 sql_variant
)
returns nvarchar(4000)
as
begin
declare #Null nvarchar(4) = N'NULL';
set #String = replace(#String, N'{0}', cast(isnull(#Param0, #Null) as nvarchar(4000)));
return replace(#String, N'{1}', cast(isnull(#Param1, #Null) as nvarchar(4000)));
end
For three placeholders {0}, {1} and {2}:
create function dbo.Format3
(
#String nvarchar(4000),
#Param0 sql_variant,
#Param1 sql_variant,
#Param2 sql_variant
)
returns nvarchar(4000)
as
begin
declare #Null nvarchar(4) = N'NULL';
set #String = replace(#String, N'{0}', cast(isnull(#Param0, #Null) as nvarchar(4000)));
set #String = replace(#String, N'{1}', cast(isnull(#Param1, #Null) as nvarchar(4000)));
return replace(#String, N'{2}', cast(isnull(#Param2, #Null) as nvarchar(4000)));
end
and so on...
Such an approach allows us to use these functions in SELECT statement and with parameters of nvarchar, number, bit and datetime datatypes.
For example:
declare #Param0 nvarchar(10) = N'IPSUM' ,
#Param1 int = 1234567 ,
#Param2 datetime2(0) = getdate();
select dbo.Format3(N'Lorem {0} dolor, {1} elit at {2}', #Param0, #Param1, #Param2);

Actually there is no built in function similar to string.Format function of .NET is available in SQL server.
There is a function FORMATMESSAGE() in SQL server but it mimics to printf() function of C not string.Format function of .NET.
SELECT FORMATMESSAGE('This is the %s and this is the %s.', 'first variable', 'second variable') AS Result

Here is my version. Can be extended to accommodate more number of parameters and can extend formatting based on type. Currently only date and datetime types are formatted.
Example:
select dbo.FormatString('some string %s some int %s date %s','"abcd"',100,cast(getdate() as date),DEFAULT,DEFAULT)
select dbo.FormatString('some string %s some int %s date time %s','"abcd"',100,getdate(),DEFAULT,DEFAULT)
Output:
some string "abcd" some int 100 date 29-Apr-2017
some string "abcd" some int 100 date time 29-Apr-2017 19:40

here's what I found with my experiments using the built-in
FORMATMESSAGE() function
sp_addmessage #msgnum=50001,#severity=1,#msgText='Hello %s you are #%d',#replace='replace'
SELECT FORMATMESSAGE(50001, 'Table1', 5)
when you call up sp_addmessage, your message template gets stored into the system table master.dbo.sysmessages (verified on SQLServer 2000).
You must manage addition and removal of template strings from the table yourself, which is awkward if all you really want is output a quick message to the results screen.
The solution provided by Kathik DV, looks interesting but doesn't work with SQL Server 2000, so i altered it a bit, and this version should work with all versions of SQL Server:

At the moment this doesn't really exist (although you can of course write your own). There is an open connect bug for it: https://connect.microsoft.com/SQLServer/Feedback/Details/3130221, which as of this writing has just 1 vote.

Not exactly, but I would check out some of the articles on string handling (amongst other things) by "Phil Factor" (geddit?) on Simple Talk.

this is bad approach. you should work with assembly dll's, in which will do the same for you with better performance.
