Hi all!
I am not very proud to ask this but here is my problem:
string code = "\'13\'"
The string code will have to contain following info:
'51','52','63', 'other'...
to get certain info from the database. When the querry is parsed these
values will be looked up:
....
compCode in (@code)
....
Can someone tell me why these values are not found in the DB? I figured
out that maybe he puts his own quotes so I tried the following:
"51" -->works (but only for one value?)
" \' 51\' " --does not work
"'51'" --does not work
Does anyone have some ideas how I can look up the right values? THX!
DateTime startDate = new DateTime(2006,1 2,14,0,0,0);
DateTime endDate = new DateTime(2006,1 2,15,23,59,59);
string campaignCode = "O850";
string code = "\'13\'"; //,\'51\'
string language = "NL";
string startdate = Convert.ToStrin g(startDate.Yea r + "-" +
startDate.Month + "-" + startDate.Day);
string enddate = Convert.ToStrin g(endDate.Year + "-" +
endDate.Month + "-" + endDate.Day);
// define connection
sqlConn = new SqlConnection(C ONNECTION);
// define query
sqlQuery = "select count(*) as Aantal, sum(talktime) as TalkTime, "
+ "sum(updatetime ) as UpdateTime, sum(talktime + updatetime) as
HandleTime "
+ "from [REPORTSERVERRPT].dbo.SOMETHING"
+ "where calldate @startdate and"
+ " calldate < @enddate and "
+ "compCode in (@code) and "
+ "sleutel in ("
+ "select up.sleutel "
+ "from [REPORTSERVER-RPT].dbo.TEST as up "
+ "where up.CampaignName = @campaign and "
+ "up.lang = @language)"; 11 1860

SELECT * FROM Table WHERE Field IN ('51','52','63' )
That is absolutly not the problem (but thx though ;-))
Maybe following output from sql profiler will help you guys :
Values of my parameters:
INPUT IS :
string code = "13" + "'" + "," +"'" + " 51";
OUPUT IS :
@startDate = '2006-12-14', @endDate = '2006-12-15', @campaign = 'O850',
@language = 'NL', @code = '13'','' 51'
So without asking he puts an extra quote in the string for each single
quote i use

Ah! I see what you're trying to do. You're trying to do a macro
substitution. You can't do that.
The IN operator is expecting a number of comma delimited parameters (sort
of). You're passing one parameter to it, so it treats it as the first item
in the list - not as a list of many items. I haven't explained that too
well; but I hope you see what I'm getting at.
I'm afraid you'll just have to type in the individual values.
Of course, if you can retrieve the values from a table, you can do a
subselect inside the IN operator's brackets; which could save you some
typing, I suppose.

Ah right - yes, that is standard ADO.NET behaviour for string parameters
because a single quote in T-SQL is the string variable delimter. When T-SQL
encounters a single quote, it interprets it as the beginning of a string
variable containing everything which follows until the next single quote is
reached. To get round the obvious problem of what to do with a string
variable need to contain a single quote, one single quote is converted into
two single quotes.
Peter,
Yup, you understand the problems I'm facing... I also thought of this
extra table you described, but after carefull consideration we
(programmers team) decided against that because these values will vary
(depending on the campaign).
Quote -
so it treats it as the first item
in the list - not as a list of many items. I haven't explained that too
well; but I hope you see what I'm getting at.
I'm afraid you'll just have to type in the individual values.
/Quote
Typing the individual values is the best option but I can't allow users
to change sql statements... and we explicitly decided AGAINST dynamic
SQL :(. I also considered parsing every code (51,60,...) individually
but that is not gonna work because null values can occur (not to
mention the performance issues).

Apologies - I now understand your problem too...
You can get round the problem of creating dynamic SQL client-side, but
you'll have to use a stored procedure instead and create dynamic SQL in
that. Here's an example from AdventureWorks. ..
CREATE PROCEDURE Person.TestProc
@pstrCriteria varchar(100) = NULL
AS
DECLARE @strSQL nvarchar(4000)
SET @strSQL =
'
SELECT
*
FROM
Person.CountryR egion
WHERE
CountryRegionCo de IN (' + REPLACE(@pstrCr iteria, '¬', '''') + ')'
EXEC sp_executesql @strSQL
Then, run the following SQL:
Person.TestProc '¬AD¬,¬AE¬,¬AF¬ '
The trick is to use a very uncommon character (¬, in this case) to pretend
to be the text delimiter...
I fully appreciate that this looks like a complete hacky kludge - and it
is! - but it works, it's extremely fast, it gets round the problem of
client-side SQL Injection, and I haven't found a neater way so far... :-)
''51'',''52'',' '63'',''other'' ...
(doubled single quotes - Transact-SQL considers them escaped)
should work.
