I would like to query a "accounts" table. I'd like to limit the results to include only individuals from the us. See below for what I've tried. It's close but seems to keep sorting everything by Balance instead of CreateDate.
DECLARE #AccountId UNIQUEIDENTIFIER = NULL;
DECLARE #SortBy NVARCHAR(128) = N'CreateDate';
DECLARE #SortDirection VARCHAR(4) = 'DESC';
SELECT [Accounts].[AccountId]
,[Accounts].[Balance]
,[Accounts].[CreateDate]
FROM [dbo].[Accounts]
WHERE [Accounts].[Balance] IS NOT NULL
UNION ALL
SELECT [Accounts].[AccountId]
,[Accounts].[Balance]
,[Accounts].[CreateDate]
FROM [dbo].[Accounts]
WHERE [Accounts].[Balance] IS NULL
)
I am trying to create a procedure in MySQL that insert weeks (for current year) to my week table. But there is a problem because after first row is added for the next one I get an error: number column cannot be null. I am new to MySQL so I will appreciate any help.
CREATE PROCEDURE generateWeeks()
BEGIN
SET #currentYear = YEAR(CURDATE());
SET #nextYear = #currentYear + 1;
SET #startOfCurrentWeek = CURDATE();
WHILE(#currentYear < #nextYear) DO
SET #endOfCurrentWeek = DATE_ADD(#startOfCurrentWeek , INTERVAL 7 DAY);
SET #weekNumber = WEEK(#startOfCurrentWeek, 3) -
WEEK(#startOfCurrentWeek - INTERVAL DAY(#startOfCurrentWeek)-1 DAY, 3) + 1;
INSERT INTO `week` (`number`, `start_date`, `end_date`)
VALUES (#weekNumber, #startOfCurrentWeek, #endOfCurrentWeek);
SET #startOfCurrentWeek = #endOfCurrentWeek + 1;
SET #currentYear = YEAR(#endOfCurrentWeek);
END WHILE;
END //
DELIMITER ;
EDITED:
Table Creation:
CREATE TABLE `week` (
`id` INT(11) NOT NULL AUTO_INCREMENT PRIMARY KEY,
`number` INT(11) NOT NULL,
`start_date` DATE NOT NULL,
`end_date` DATE NOT NULL
)
Why for first while iteration everything is ok (rows is added), but in the next one I get null value in #weekNumber variable ?
The line:
SET #startOfCurrentWeek = #endOfCurrentWeek + 1;
will convert the variable into a integer. Use date_add instead.
Also, instead of using user-defined variables (#endOfCurrentWeek) you better use local variabled (declare v_endOfCurrentWeek date).
I am working on a SSRS report and using a parameter that allows you to choose multiple options. However, when I do this I get an error that states:
Error Converting Data Type nVarChar to Int.
The data in the database is an Integer. The parameter is set up as an Integer and it works great when only choosing one option. The issue comes when I choose multiple options.
My co-worker came up with one work-around but I would like something a little more elegant and easier to plug in if possible.
Here is his work-around:
ALTER PROCEDURE [dbo].[DtaPrep_MktgClients]
#BegDate date = NULL
, #EndDate date = NULL
, #Species varchar(50) = 'canine,feline,K9,'
, #HospList varchar(500) = NULL
This is where the hospmastid string gets converted into a temp table
/*
--===================================--
HOSPITALS SETUP
--===================================--
*/
If #HospList IS NOT NULL
BEGIN
DECLARE #WorkHospList varchar(500)
SET #WorkHospList = #HospList
;
CREATE TABLE #HospList
( HospID smallint NULL )
SET #CommaLoc = charindex(',', #WorkHospList)
WHILE #CommaLoc > 1
BEGIN
SET #curVal = LEFT(#WorkHospList, #commaloc-1 )
INSERT INTO
#HospList( HospID )
SELECT #curVal
SET #WorkHospList = substring( #WorkHospList, #commaloc+1, len(#WorkHospList) )
SET #CommaLoc = charindex(',', #WorkHospList)
END
END
This is using the temp table to accomplish the same thing as a “WHERE Hospmastid IN (101,102,103)…”
Method 1
SELECT
HospitalMasterID
, ClientID
, FirstName
, LastName
FROM
Client
WHERE
HospitalMasterID IN (Select HospID From #HospList )
Needless to say, I am sure there is a better way to accomplish this. If anyone has any ideas, please let me know.
Here is the full Query I am now using. But it is not selecting anything so there is an issue with the Created Table.

Prior to SQL Server 2008, the standard way to filter by one or more values was to pass an XML document to the Stored Procedure and join on it. In this case, you could pass the data as a string with the integers separated by commas, then convert that into an XML document, then join on the XML. So you should change the multiselect in SSRS to a text datatype. Here's a post that shows you how to open an XML document: http://blog.sqlauthority.com/2009/02/13/sql-server-simple-example-of-reading-xml-file-using-t-sql/
SQL Server 2008 lets you use table-valued parameters, but again, it might be best to pass the data as a string of comma separated integers and then let the stored procedure put the data into a table-valued parameter, and then join on that. Here's a post that describes how to use table valued parameters: http://blog.sqlauthority.com/2008/08/31/sql-server-table-valued-parameters-in-sql-server-2008/
I've got the following SQL statement that I am working on. I've trimmed it down to the parts necessary to illustrate the problem.
DECLARE #mwareId as int = 9647,
#startDate as datetime = '2011-07-20',
#endDate as datetime = '2011-07-20'
IF OBJECT_ID('tempdb..#tmpInvoiceList', 'U') IS NOT NULL DROP TABLE #tmpInvoiceList
-- Get base invoice list for customer
SELECT invoiceId
,invoiceNumber
,customerId
,customerName
,customerCode
,createDate
,lastModifiedDate
,invoiceDate
,totalInvoiceAmount
,statusId
,isPaid
INTO #tmpInvoiceList
FROM Invoice.Invoice
-- Apply date range if applicable
IF ( #startDate != NULL AND #endDate != NULL )
BEGIN
DELETE FROM #tmpInvoiceList
WHERE invoiceDate NOT BETWEEN #startDate AND #endDate
END
SELECT * FROM #tmpInvoiceList
I have the #startDate and #endDate variables set to date values. The problem is that the if block that applies the date range to the temp table is not executing, though neither of the two variables are null, and I can't find a reason for this.
As far as I'm aware, TSQL doesn't support the != operator for null checks. Try this:
IF ( #startDate IS NOT NULL AND #endDate IS NOT NULL )
IS [NOT] NULL is the right way to compare value with NULL. All of (NULL != NULL) , (1!= NULL), (NULL =NULL) evaluate as NULL(false)
You have to use IS NOT NULL instead of != NULL
IF ( #startDate IS NOT NULL AND #endDate IS NOT NULL )
...
I have a select statement which contains a number, description, date. when i try to add my date to the statement and run it i get a date conversion from character string error and i am not really sure how to go about it.
DECLARE #parties AS TABLE (
PartyId UNIQUEIDENTIFIER
, Cases NVARCHAR(MAX)
, CaseTypes VARCHAR(MAX)
, Assignment DateTime)
DECLARE #cases NVARCHAR(MAX)
DECLARE #casetypes VARCHAR(MAX)
DECLARE #assignment DateTime
DECLARE #linebreak AS VARCHAR(2)
SET #cases = NULL
SET #casetypes = NULL
SET #assignment = NULL
SET #linebreak = CHAR(13) + CHAR(10)
SELECT #cases = COALESCE(#cases+ #linebreak + C.CaseNumber, C.CaseNumber)+"-"+CT.[Description]+"-"+A.DateOn
FROM [Case] C
INNER JOIN CaseType CT ON C.CaseTypeId = CT.CaseTypeId
INNER JOIN #partyCases PC ON C.CaseId = PC.CaseId
INNER JOIN Appointment A ON C.CaseId = A.CaseId
WHERE PC.PartyId = #partyId
The error occurs after adding A.DateOn to my select statement and running it - any suggestions will be great. Thanks!
SQL returns Date values as datetime and such values can not be implicitly used as strings (varchars). You will have to explicitly convert or cast them. So, change your select statement in either of the 2 ways below:
SELECT #cases = COALESCE(#cases+ #linebreak + C.CaseNumber, C.CaseNumber)+"-"+CT.[Description]+"-"+CONVERT(varchar, A.DateOn)
OR
SELECT #cases = COALESCE(#cases+ #linebreak + C.CaseNumber, C.CaseNumber)+"-"+CT.[Description]+"-"+CAST(A.DateOn as varchar)
CONVERT has a slight advantage - you can apply formatting on the date, if you want.
