I've seen lots of entries recommending the use of ISNULL in SQL WHERE clauses, e.g. in a search sproc where users can enter some or all parameters to search a table. Previously I would have used something like:
SELECT * FROM MyTable
WHERE (FName = @fname OR @fname IS NULL) AND
(MName = @mname OR @mname IS NULL) AND
(LName = @lname OR @lname IS NULL)
So using the neat ISNULL syntax it could be updated to:
SELECT * FROM MyTable
WHERE (FName = ISNULL(@fname, FName)) AND
(MName = ISNULL(@mname, MName)) AND
(LName = ISNULL(@lname, LName))
Having played around with this I stumbled upon a problem. If one of the fields, e.g. MName, is NULL then that clause will return false since MName = NULL isn't true and you have to use MName IS NULL. Did I miss all the caveats with using ISNULL in this way on fields that can contain NULL or have I missed something else?
I need to be able to construct a statement that says something like:
If advertiserTYPE = FSBO Then INSERT INTO [COLUMN1] If advertiserTYPE = BROKER Then INSERT INTO [COLUMN2 If advertiserTYPE = DEVELOPER Then INSERT INTO [COLUMN3]
I have this sproc. ALTER PROCEDURE dbo.cis_UpdateCourseUserWithGrade @Grade nvarchar, @UaaStudentId nchar, @CourseId int AS UPDATE cis_CourseUser SET Grade =@Grade WHERE UaaStudentId = @UaaStudentId AND WHERE CourseID = @CourseId RETURN the ANE WHERE isn't much liked. How can I update the field with the grade where both of the conditions are true? I'm getting an invalid syntax near @UaaStudentId
So how do you do dynamic WHERE clauses with asp.net? I have a QueryString parameter with a value that will look like this. |1| or |1||2| or |1||2||3| or etc. For each number in the value I want to add an EXISTS function to the WHERE clause. I have accomplished this in T-SQL. But I can't figure out how to bind asp.net control to it. It gives me 'Invalid syntax near the keyword 'ORDER'. I know this has something to do with .net not being able to exaluate the schema properly. So I tried Linq to Sql. Well, so happens that my WHERE clause is pointing to the existance of records in another table which the default install of Linq to Sql doesn't seam to support. I came across this post (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2979081&SiteID=1) that explains how to dynamically query across multiple tables. I tried this and got errors when trying to plug in the additional code. And this still does not let me dynamically add where clauses. I tried the who Predicate thing and ran into the same problem where I can't reference the existance of values in foreign tables. Here is my sproc. Can anyone tell me how to get this into a asp.net environment. I also do NOT want to auto-generate fields in my GridView.ALTER PROCEDURE dbo.Item_SelectByFilters @Item_Category_Id int = NULL, @ItemSpecificValueIdList varchar(100) = NULL, @debug bit = 0 AS DECLARE @sql nvarchar(4000), @paramlist nvarchar(4000) SELECT @sql = 'SELECT Item_Id, Number, Primary_Item_Category_Id, Secondary_Item_Category_Id, Engineering_Document_Id, CategoryIdList FROM Item WHERE (1 = 1)' IF @Item_Category_Id IS NOT NULL SELECT @sql = @sql + ' AND Item.CategoryIdList Like ''|'' + CONVERT(varchar, (@xItem_Category_Id) + ''|''' IF @ItemSpecificValueIdList IS NOT NULL BEGIN WHILE @ItemSpecificValueIdList <> '' BEGIN DECLARE @StartLocation int SELECT @StartLocation = CHARINDEX('-', @ItemSpecificValueIdList, 1) IF @StartLocation <> 0 BEGIN DECLARE @EndLocation int SELECT @EndLocation = CHARINDEX('|', @ItemSpecificValueIdList, @StartLocation + 1) IF @EndLocation <> 0 BEGIN DECLARE @ValueLength int SELECT @ValueLength = @EndLocation - @StartLocation - 1 DECLARE @ValueBetween varchar(10) SELECT @ValueBetween = SUBSTRING(@ItemSpecificValueIdList, @StartLocation + 1, @ValueLength) IF @ValueBetween IS NOT NULL SELECT @sql = @sql + ' AND EXISTS(SELECT Item_Specific_Value_Id FROM Item_Specific_Value WHERE Item_Id = Item.Item_Id AND Item_Specific_Value.Item_Specific_Value_Id = ' + @ValueBetween + ')' END END SET @ItemSpecificValueIdList = SUBSTRING(@ItemSpecificValueIdList, @EndLocation + 1, len(@ItemSpecificValueIdList) - @EndLocation) END END SELECT @sql = @sql + ' ORDER BY Item.Number' IF @debug = 1 PRINT @sql SELECT @paramlist = '@xItem_Category_Id int' EXEC sp_executesql @sql, @paramlist, @Item_Category_Id
Here is another project that seams to be the same as my previous post but a little simpler. http://forums.asp.net/t/1263330.aspx My Item_Category table is self referencing. I have a list of category Ids in a particular order representing the tree of categories from the current category to the top. For example: 1 - Fasteners, 4 - Screws, 12 - Sheet Metal Screws or the reverse. I need to translate this so I can bind a cookie crumb type control to it. ie. Fasteners > Screws > Sheet Metal ScrewsI originally accomplished this like so; Dim q = From ic In itemdc.Item_Category _Where valueId.Contains(ic.Item_Category_Id) _ Select Id = ic.Item_Category_Id, ic.Name But found that this does not order them properly. Remember that the list of Ids is in a particular order. I need a query to result to the below. I was using a horizontal DataList control as the cookie crumb control. Again, I am trying to do this with Linq to Sql without using Stored Procedures even though I am the DBA as well. Or is there some other better way to do this?
Id Name Sort
1 Fastener 1
4 Screws 2
12 Sheet Metal Screws 3 Finally, as I mentioned in my previous post, I accomplished this concept with a stored procedure but then the asp.net controls could not recognize the schema, hence I could not bind the controls to the data source control.
I have an existing SPROC which works the way it should do and was difficult to construct. But now I need to add 1 more condition and hopefully that should be it however I am struggling how to do this. Here is a snip of the existing SPROC.
quote: IF @columnName = 'Rating - Fire' OR @columnName = 'Rating - PPE' OR @columnName = 'Rating - Reactivity' OR @columnName = 'Rating - Health' BEGIN SELECT @totalRecords = (SELECT COUNT(p.[SID]) FROM S_Summary p INNER JOIN S_Detail detail ON detail.SID = p.SID WHERE CASE @columnName
[code]...
so this works fine but now I need to add 1 more thing..if a new parameter is supplied (lets call it @stringBranch), then I want to join another table and also match the param value to a field in that table along with any existing WHERE conditions being applied to this:
quote: WHERE (@columnName IS NULL AND @columnValue IS NULL) OR CASE @columnName WHEN 'Rating - Fire' THEN detail.F WHEN 'Rating - PPE' THEN detail.P
I'm trying to use multiple where clauses but its not working. I want it to look something like this:
INSERT INTO [USCondex_Development].[dbo].[miamiheraldExceptions]([InvalidEmails], [InvalidAdPrintID], [InvalidPropertyStreetAddress], [InvalidPropertyPrice]) SELECT [AdvertiserEmail],[AdPrintId],[AdvertiserAddress], [PropertyPrice] FROM [Development].[dbo].[table2] WHERE advertiseremail is NULL and WHERE adPrintID is NULL and WHERE firstinsertdate is NOT NULL and WHERE propertystreetaddress is NOT NULL and WHERE propertyprice < 100
I am trying to wrap my WHERE clause with an IF or a CASE but cannot seem to get it to work. This is what I am trying:
WHERE CASE WHEN EVENT_TYPE='d' THEN (link_inc.incident_id = 10000005) AND (B.incident_id <> 10000005) AND link_rsn.link_rsn_sc = 'CHANGE' AND B.incident_id > 10000000 ELSE (link_inc.incident_id = 10000005) AND (B.incident_id <> 10000005) AND link_rsn.link_rsn_sc = 'CHANGE' AND B.incident_id > 10000000 AND act_type.act_type_sc <> 'CLOSURE' END ORDER BY B.incident_id DESC, act_reg.act_reg_id DESC
Basically I want to run a different WHERE clause based on a value (EVENT_TYPE). The error message I am getting is: Incorrect syntax near '='.
I have a table, basically consisting of products and their prices. I want to select some products, then sort them by price in ascending order BUT putting prices of zero at the bottom. (e.g. 5.99, 8.99, 10.99, 0.00, 0.00)I thought I'd be able to do something like:ORDER BY (price != 0), pricethinking that it would sort rows according to whether the condition was true or not, and then by price, but MSSQL doesn't seem to allow this. should this work, or is there another way around this? One solution would be to load the values into a table object and sort them using that, but I'd rather do all of this in SQL if possible, for speed.any suggestions?thanks!
If I have a table called "content_hits_tbl" and want to pull information, can't i write something like this:
SELECT COUNT(visitor_id) AS HITS, COUNT(DISTINCT visitor_id) AS VISITORS, COUNT(DISTINCT visitor_id) WHERE visit_type = 0 AS NEW, COUNT(DISTINCT visitor_id) WHERE visit_type = 1 AS RETURNING FROM content_hits_tbl
Can't you have multiple WHERE clauses in the SELECT statement?
Any suggestions would be great. I have been wrestling with it and SQL queries arent my strong area ...
I have a Master table with a OrderNbr which is also contained in the Detail table.
It's a 1 to Many relationship, respectively.
I want to update the MASTER.FinalizedDate using a "select top 1 FinalizedDate order by FinalizedDate DESC" from the Detail table but the clause is ALL the Status have to be "F". So OrderNbr 12345 should not get updated because it contains a 'O'. OrderNbr 67899 should get updated in the Master table to 2/26/2013 because all have a 'F' and the last date to post is the official finalized date.
Here is what I came up with.......so far, but not sure how to work in the Status piece on 1 to M.
The rub here is that even if one row has the 'O' status I want to ignore the update. If all have the 'F' then I want the udpate to happen.
Update MASTER Set FinalizedDate = (select top 1 d.FinazliedDate from Detail d where m.OrderNbr = d.OrderNbr and d.Status not in ('O') Order by FinalizedDate DESC) From MASTER m
How do I not include all 3 rows for OrderNbr 12345 because one row has the Status "O" in the DETAIL table?
Here are the table looks........
MASTER OrderNbr Ytotals Ztotals Xtotals Finalized Date 12345$1,500$1,500$1,200 67899$1,200$1,100$900
In a UDF, how is the best way to extend a query with additional clauses based on expressions? The user input here is used to refine the basic query by introducing additional clauses. Is there something like the following?
-- The basic query SELECT column FROM table WHERE clause
-- Additional clause, only appended to query -- if expression evaluates to true IF @parameter <> default_value BEGIN AND additional_clause END
Right now I'm using CASE like the following, but it necessarily makes the query longer. Is there a more efficient way?
-- The basic query
SELECT column FROM table WHERE clause
-- Additional clause, should only effect result -- set when the parameter is not default_value AND table.column = CASE @parameter WHEN default_value THEN -- identity, table.column=table.column, -- should have no effect other than just a long query table.column ELSE @parameter END
Hi I'm not sure if I have stated my subject line correctly for what I want to achieve, but I will attempt to explain it below.
In addition to what I have in my script below, I also need to include the following clauses:
1. where TransPerPaySequence.FinancialYTDCode like '2007', and e.EmployeeStatusCode like 'CASUAL' and p.PositionGroupCode like 'AC', then instead of using the divisor of 72, it needs to be 35; and
2. where TransPerPaySequence.FinancialYTDCode like '2008', and e.EmployeeStatusCode like 'CASUAL' and p.PositionGroupCode like 'AC', then instead of using the divisor of 72 or 35, it needs to be 31.
I would really appreciate any assistance that can be provided.
Thanks

Hi, I hope some one can help me. I have a stored procedure (Microsoft SQL 2005 Express Edition) that I want users to be able to dynamically set the, group by, order by (@orderby) and where clause (@where).

I have a web page which passes back parameters to a stored procedure. From the web page the user selects different clauses for the 'where' criteria. Based upon the number of clause items in the parameters sent back, a select statement is built and executed. In the stored procedure I have many if statements to chose the correct sql statement. As the no of clauses in the where statement can vary, it can become messy script. Has anyone dealt with this scenario. What is the best strategy ?
A simple illustation of this is as follows A statement with two clauses :-
Select * from Sales where user = 'John' and country = 'England' A statement with three clauses :- Select * from Sales where user = 'John' and country = 'England' and County = 'Staffordshire'
The stored procedure would except three parameters and would build a string based on the number of actual where clases sent back
I have a complex SQL query against multiple tables that ideally would be best used as a stored procedure.
I know of and have read about creating named parameters and setting the parameters' values in ASP just before issuing an execute command via the Command object. What I'd like to do is assign the text of the filter and sort clauses to the parameters. Not the values, but the entire string, such as
"WHERE lastname LIKE 'A%' "
"ORDER BY lastname "
I need to assign the entire clause because the query may or may not use a particular clause.
I have experimented. However SQL treats the parameter as a literal string rather than part of the SQL query itself. Is there another technique that I may use to accomplish my goal?
Thanks in advance for your opinion, suggestion, criticism, etc.
I came across this structure today and haven't seen it before:
SELECT blablabla FROM T1 FULL OUTER JOIN T2 ON T1.Col1 = T2.Col1 AND T1.Col2 = T2.Col2 ON T3.Col1 = T1.Col1 AND T3.Col2 = T1.Col2 ON T4.Col1 = T1.Col1 AND T4.Col2 = T1.Col2
dbo.TAG ON dbo.KALENDER.KALENDER_ID = dbo.TAG.KALENDER_ID INNER JOIN
dbo.STUNDE AS s ON dbo.TAG.TAG_ID = s.TAG_ID
WHERE ((SELECT MONTH(s.datum_zeit) AS Expr1
FROM ) =
(SELECT MONTH(GETDATE()) AS Expr1) - 2) AND
((SELECT YEAR(s.datum_zeit) AS Expr1
FROM ) =
(SELECT YEAR(GETDATE()) AS Expr1))
ORDER BY s.STUNDE_ID
... but this causes syntax-errors. I don't understand why this query works fine in the query editor but then gets automatically "destroyed" by the view editor. Do i have to use more statements to get the working query to run inside a view?
for the query i created i need zeros where ever the filed is blank. i have used count(acc) for selecting the count . can any one help me out with sample query. Thanks in advance
I have two tables, tblMTO and tblIMPORT_MTO. If I import an entire MTOinto the import table I want to create a delta from it (i.e. leave onlythe changed items).

does sql server mobile 2005 support the isnull function? I'm getting an error when I try to use it and I don't know if it is becuase of using the isnull function or not, but when I run the same query on Sql Server 2005 it works fine.
I've got this query and it use to work or at least I thought it did. Could someone please help me with it. Thank you SELECT CID, CompletionDate, MarkedExport, CustomerName, EditUser, RouteID, WorkOrder FROM RouteCustomer WHERE (CompletionDate IS NOT NULL) AND (ExportDate IS NULL) AND (RouteID LIKE '%' + ISNULL(RouteID,@RouteID) + '%') AND (EditUser IS NULL OR EditUser = '' OR EditUser = @EmployeeID) AND (MONTH(CompletionDate) = ISNULL(MONTH(CompletionDate),@Month)) The problem comes with in the WHERE clause. What I wanted it to do is if the user did want to use a RouteID critera then the user would speified one else it wouldn't, and it was my belief that the ISNULL feature in SQL was the answer for that. same for the Month. I believe the EditUser is fine the way it is written. thanks to anyone that can help me with this. Rex
I have to display string "not assigined" when a datefield is null in a table. I am using like ISNULL(datefiled, "not assigned"), but I am getting following error Syntax error converting character string to smalldatetime data type. Is there any way, I can acheive desired result. Please help
To give you a little background, there is a CRM system with SQL server as its back-end. The CRM uses a view in SQL Server to list all the communications a user has had with his client over any given interval of time. Now there is a requirement to add a new column in the view that tells a user if the communication was filed in automatically or if it happened overnight via an automated archive manager process. I have achieved this using an expression field which is based on the comm_url field in the communications table in database.
example:
create view vCommunications as select col1, col2,...,case when comm_url is null then 'Manually filed' else 'Automatically Filed' as Filing from Communications
alternatively, this can also be achieved by the following:
create view vCommunications as select col1, col2,...,isnull(comm_url, 'Manually Filed') as Filing from Communications
Now my question is, given that there are many rows in the communications table, which of the above two expression fields will be more efficient in performance i.e. CASE versus ISNULL. I've checked a lot on google but I haven't been able to come up with a concrete answer.
Hey, I'm taking an intro SQL Server class, and I have a pretty simple homework assignment. We were provided with a DB and asked to write several SELECT statements. However, I'm stuck up one of the questions. Here is the question: 12.Create a SELECT statement that displays all employees and their Qualifications. Display that individuals with no Qualifications as having ‘NoQual’. Hint: Use a function to determine this ‘empty’ field using ISNULL.
Here is what I have:
SELECT FNAME + ' ' + LNAME AS 'Employee Name', ISNULL(QUALID, 'NoQual') AS 'Qualifications' FROM EMPLOYEE, QUALIFICATION WHERE EMPLOYEE.QUALID = QUALIFICATION.QUALID;
However, I do not get any results that have a NULL value in the QUALID column. Here is the code for the DB:
INSERT INTO position VALUES (1, 'President'); INSERT INTO position VALUES (2, 'Manager'); INSERT INTO position VALUES (3, 'Programmer'); INSERT INTO position VALUES (4, 'Accountant'); INSERT INTO position VALUES (5, 'Salesman');
INSERT INTO emplevel VALUES (1, 1, 25000); INSERT INTO emplevel VALUES (2, 25001, 50000); INSERT INTO emplevel VALUES (3, 50001, 100000); INSERT INTO emplevel VALUES (4, 100001, 500000);
INSERT INTO qualification VALUES (1, 'Doctorate'); INSERT INTO qualification VALUES (2, 'Masters'); INSERT INTO qualification VALUES (3, 'Bachelors'); INSERT INTO qualification VALUES (4, 'Associates'); INSERT INTO qualification VALUES (5, 'High School');
INSERT INTO dept VALUES (10, 'Finance', 'Charlotte', 123); INSERT INTO dept VALUES (20, 'InfoSys', 'New York', 543); INSERT INTO dept VALUES (30, 'Sales', 'Woodbridge', 135); INSERT INTO dept VALUES (40, 'Marketing', 'Los Angeles', 246);
I'm having a problem creating a isnull statement. I want to do two things I want to list all of the accounts that have a null value in a numeric field. And I want to update those accounts to 0.00. I tried: select Account_Num, isnull(TotalDDMFEE, 0) FROM Addr_20080402 But it returned all records
For the update I tried: update Addr_20080402 CASE when TotalDDMFEE = ' ' then TotalDDMFEE = 0.00 AND update Addr_20080402 CASE when TotalDDMFEE = isnull(TotalDDMFEE, 0) then TotalDDMFEE = 0.00
Any ideas how I should have written these two queries? Thanx, Trudye
okay, using isnull function we could replace null value.. but i want to do opposite, i want to replace if it's NOT null.. i tried notisnull also cannot..
