Hi All,
i have this data:
DECLARE @tblCron TABLE(
id INT ,Nivel INT,
A INT,
B INT,
C INT,
D INT
)
INSERT @tblCron
SELECT 1202337,1,0,0,0,0UNION ALL
SELECT 1202338,2,0,0,0,0UNION ALL
SELECT 1202339,3,0,0,0,0UNION ALL
SELECT 1202340,4,7,7,7,4UNION ALL
SELECT 1202341,4,4,7,8,2UNION ALL
SELECT 1202342,1,0,0,0,0UNION ALL
SELECT 1202343,2,0,0,0,0UNION ALL
SELECT 1202344,3,0,0,0,0UNION ALL
SELECT 1202345,4,7,7,7,4
SELECT * FROM @tblCron
I need the result to be (with a select statement):

What have you tried so far?

I am curious why you are formating the output in the SQL code. What you are asking for should really be done in the UI.
March 26, 2012 at 9:35 am
Really? Did you actually try this on your own first?
SELECT id, Nivel,
CASE WHEN A = 0 THEN '' ELSE CAST(A AS CHAR(1)) END AS A,
CASE WHEN B = 0 THEN '' ELSE CAST(B AS CHAR(1)) END AS B,
CASE WHEN C = 0 THEN '' ELSE CAST(C AS CHAR(1)) END AS C,
CASE WHEN D = 0 THEN '' ELSE CAST(D AS CHAR(1)) END AS D
FROM @tblCron

Yeah, that too ^^

REPLACE works too 😀
SELECT id,Nivel,REPLACE(A,'0','')A,REPLACE(B,'0','')B...
FROM @tblCron

SELECT id,Nivel,REPLACE(A,'0','')A,REPLACE(B,'0','')B...FROM @tblCron
I try to avoid implicit conversions where possible

The other thing is that it's not a general solution. Consider what would happen if the data include 10 instead of just single digit numbers. I seriously doubt that the OP wants the output to be "1" in that case.

That data r results from a dynamic query,
well that result i input to a temporary table, and then i made a update.
my test query:
DECLARE @sql NVARCHAR(MAX)
DECLARE @colCampoREPLACE VARCHAR(MAX)
DECLARE @C INT=1
DECLARE @cc INT=10
SET @colCampoREPLACE=''
BEGIN
--'C'+CONVERT(VARCHAR,@C)
SET @colCampoREPLACE = @colCampoREPLACE + 'c'+ CONVERT(VARCHAR(2),@C) +'='''','
SET @C=@C+1
END
SET @colCampoREPLACE=SUBSTRING(@colCampoREPLACE,1,LEN(@colCampoREPLACE)-1)
print @colCampoREPLACE
SET @sql='
UPDATE #tbl_Cron
SET '+@colCampoREPLACE+'
WHERE NIVEL_partida_cliente in (1,2,3)
'
EXEC sp_executesql @sql
print @sql
The problem was solved, but maybe exists anothe best way :ermm:

First, I really don't see how this solves your problem. And two, you haven't answered the question as to why you want to return blanks for 0's in your query instead of allowing the UI to handle the proper display of data.

Dependin of the column "Nivel",
if that have a value of 1 or 2 or 3 the columns 'A','B','C','D' must be empty,

I will ask again, why can't this be handled by the UI? Why do you have to do it in the select statement?
March 26, 2012 at 1:33 pm
For the perfomance mostly..

I think the UI would be the better place for this then, I don't see doing the conversion in the query being better for performance.

Meaning you want to slow down sql to format data for display? 😀

The select of this UI is a PIVOT statement.
with the query att. the perfomance is OK, and if i handle by the UI i have the read 1 record by 1 and asking her "nivel" after change the 0 for the entire row empty.
Sorry, bad engl.
