I found a code snippet that use the curious following sintax on the creation of View:
CREATE VIEW [dbo].[vw_EvenValues]
AS
SELECT [TestColumn]
FROM [dbo].[TestTable]
WHERE [TestColumn] % 2 = 1
[code]....
IF [TestColumn] on the Select is varchar, then error occurs and say:"Conversion failed when converting for the varchar value 'A001' to data type int"
I have a table which gets updated with the usage figure every week. Any similar t-sql which returns the increase in usage percentage of all the columns.
View 8 Replies View RelatedI have a table of People and their ID, the starting month (a fixed number of months, say 10 for this), the ending month, and the percent of work time (0-1 being 0-100%). If they have a % work of 0, I do not want to see anything. But if the % changes, from say .5 to .75, I would need the first and last month they were at .5, and the first and last month they were at .75

We have a table to 100M rows and up until now we were fine with an non clustered index a varchar(4000) because we never went above 900 bytes (yes it is a bad design).We have the need to support international character sets now so the column was updated to nvarchar(4000) and now we have data past the 900 byte limit.
The data is long, seems useless but is needed by the business and they need to be able to search "where bigcolumn like 'test%'". With an index, even with a huge amount of data, it was 'fast'. Now of course without an index it is unusable. The wildcard is always at the end of the search. I made a full text index on the column and basic queries such as: select * from ourtable where contains(bigcolumn, 'AReallyLongStringofTextHere') works fine unless there is a space in the data. We loose thousands of returned rows because of spaces in the data.
I have tried select * from ourtable where contains(bigcolumn, '"AReallyLongStringofTextHere that includes spaces"') but not all of the data is returned. I get 112 rows with the contains statement. The table scanning statement of "select * from ourtable where bigcolumn like 'AReallyLongStringofTextHere that includes spaces%' returns 1939 rows.I understand that a full text index is breaking the long string up since it contains spaces. Is there a way to retain the entire string as 1 index entry or is there a way to fix my query to return all of the rows?

I am working on a project that was assigned to me that has to do with data in one of our SQL databases. I have the following query that takes information from a single table and averages test scores for each student.
--Group all scores from same student and average them together
with cte_names as
(
SELECT StudentID, MAX(StudentName) AS StudentName
FROM LDCScores
WHERE schoolYear='2014-2015' AND term = 3
GROUP BY StudentID
[code].....
I now need to take the results from the above query and determine the percentage of students, per school that scored a 2 or greater in grade 7 for each test. For grade 8 scored a 2.5 or greater, grade 9 scored a 3 or greater, grade 10 scored a 3 or greater, grade 11 scored a 3.5 or greater, and grade 12 scored a 3.5 or greater.
From MS Dynamics NAV 2013 I get a lot of querries that have a where clause like this:
where [Field1] like @p1 and [Field1] < @p2.
Field1 is the only primary key field and clustered index. The query also has a TOP 50 clause.
@p1 is always a "Starts-With"-value (something like N'abc%').
The query plan uses a clustered index seek but the number of reads look more like a clustered index scan.
Depending on the table size I see 1M or more reads for these querries.
If I rebuild the query in SSMS, but replace the paramerters with actual values I only see a few reads.
I was able to reproduce the issue with a temp table. See code below.
Is there a way to make SQL Server use another strategy when using the parameterized query?
SQL Server Version is 11.0.3401.
if object_id('tempdb..#tbl') is not null
drop table #tbl;
create table #tbl
(
[No] nvarchar(20)
,[Description1] nvarchar(250)
[Code] ....
Right now I have to do something like this and it is time consuming every time I have to query a specific table...
SELECT lots_of_columns
FROM table
WHERE (column5 = '1' OR column6 = '1' OR column7 = '1' OR column8 = '1' OR column9 = '1' OR column10 = '1' OR column11 = '1' OR column12 = '1')
AND other_query_critiera_here
Typing out the OR statement gets long, time consuming and prone to errors because that first where line with all the ORs can sometimes have 20+ ORs in it. As some insight, the columns are text columns, sometimes they have data, sometimes they are NULL. Sometimes they have the same data (i.e., column5 and column6 and column12 could both have '1' as values).
I would like to be able to combine the functionality of IN and LIKE in a WHERE clause. Although the simple AdventureWorks2012 example below illustrates the concept with 3 search criteria, the real-world example I need to apply the concept to has a couple dozen. This returns 50 rows, but requires multiple OR ... LIKE functions:
SELECT DISTINCT c.Name
FROM Sales.Store c
WHERE c.Name LIKE '% sports %'
OR c.Name LIKE '% exercise %'
OR c.Name LIKE '%toy%'
What I would like to do is something like this, which doesn't work:
SELECT DISTINCT c.Name
FROM Sales.Store c
WHERE c.Name IN(LIKE '% sports %', LIKE '% exercise %', LIKE '%toy%')
I could load up a cursor and loop through it, but the syntax is more cumbersome than the multiple LIKE statements, not to mention most SQL programmers are horrified at the mention of the abominable word 'cursor' for performance reasons.
A while back, a "quirky update" method was proposed for lightning fast running totals based on the three-part MSSQL UPDATE's SET statement and tally tables. However, some claimed this was not 100% absolutely guaranteed behavior.
How does the new OVER clause compare in terms of performance ?
DECLARE @Tbl TABLE
(
pk int not null primary key identity,
N int
)
INSERT INTO @Tbl (N) SELECT TOP 1000 1 FROM syscolumns a CROSS JOIN syscolumns b
SELECT pk, SUM(pk) OVER (ORDER BY pk )
FROM @Tbl
I am creating a dynamic query where i am appending a where clause something like -
IF (@CurCaptureDate IS NOT NULL)
SET @where_clause = @where_clause + CHAR(10) + 'AND CD.CaptureDate = ' + @CurCaptureDate
PS - CD.CaptureDate is datetime and @CurCaptureDate is also datetime
but when executing , it gives this error - Msg 241, Level 16, State 1, Line 169 Conversion failed when converting date and/or time from character string.
i am not able to use convert here with these quotes.
i tried this - SET @where_clause = @where_clause + CHAR(10) + 'AND CD.CaptureDate = ' + CONVERT(VARCHAR(25),@CurCaptureDate )
but it makes it to -
AND CD.CaptureDate = Jul 19 2014 12:00AM. I would need the date in quotes.
Because of the way in which a specific piece of code is written, I'm bound into using a WHERE clause for a report generation.Each Inspection generates a unique Inspection Number. Any re-inspection created from that inspection is assigned that Inspection Number and appended with ".A", ".B", ".C" and so on.
The problem is this: Each row's Primary Key is the "InspectionId" in "dbo.v_InspectionDetailsReports". I need to return not only the data related to that particular InspectionId, but also the data related to any previous related inspection. For example, if I have a main number of CCS-2012 and three re-inspections, CCS-2012.A, CCS-2012.B and CCS-2012.C, and I report on CCS-2012.B, I need all the data for CCS-2012, CCS-2012.A and CCS-2012.B but NOT CCS-2012.C.
I would prefer to not have to do everything in a WHERE statement, but my hands are a bit tied.
The "SELECT * FROM dbo.v_InspectionDetailsReports WHERE . . ." is already hardcoded (don't ask).
SELECT *
FROM dbo.v_InspectionDetailsReports
WHERE ( RefOnly = 0
OR RefOnly IS NULL

I am using an aggregate with the OVER clause.Running the script is fast less than 1 second but when I say insert into a temp table the execution plan is very different at it take 8 seconds.I have attached the execution plans. Also the Statistics IO, Time messages. I am using SQL Server 2014 with backward compatibility to 2008 R2.
if (select OBJECT_ID('tempdb..#MM')) is not null drop table #MM
CREATE TABLE #MM ([MyTableID] [int], [ParticipantID] [int], [ConferenceID] [nvarchar](50), [Points] [money], [DateCreated] [datetime], [StartPoints] [money], [EndPoints] [money], [LowPoints] [money], [HighPoints] [money])
insert into #MM ([MyTableID], [ParticipantID], [ConferenceID], [Points], [DateCreated], [StartPoints], [EndPoints], [LowPoints], [HighPoints])
selectmm.MyTableID, mm.ParticipantID, mm.ConferenceID, mm.Points, mm.DateCreated,

I'm looking at various methods for deleting duplicate rows. Among the alternatives, one works just fine but gives me results that make me go?.
Consider this script:
declare @t table (a int, b int, c int, d int, e int)
insert into @t (a, b, c, d, e) values
(1, 2, 3, 4, 5),
(3, 4, 2, 3, 4),
(1, 2, 3, 4, 5)
select a,b,c,d,e, rn = row_number() over (
partition by a,b,c,d,e
[Code] ....
The code works -- that is, the duplicate row is deleted. However the output clause returns:
abcdern
123451
So....why? Why does the output clause show that the row with rn=1 was deleted, when the where clause stipulates rn > 1?
I have 10k indexes I need to rebuild and each time the script reaches an error it stops all further activity. How can I append 'GO' to the end of each line so it will continue on error messages?
Once I have the syntax I can do a find and replace function in Notepad++
USE [AdventureWorks2014] + char(13) + char(10) + GO
ALTER INDEX [IX_Person] ON [Person].[Person] REBUILD PARTITION = ALL WITH (PAD_INDEX = OFF) + char(13) + char(10) + GO
ALTER INDEX [IX_Emp] ON [HumanResources].[Employee] REBUILD PARTITION = ALL WITH (PAD_INDEX = OFF) + char(13) + char(10) + GO

How I am using a CASE statement within a WHERE clause to filter data:
CREATE PROCEDURE dbo.GetSomeStuff
@filter1 varchar(100) = '',
@filter2 varchar(100) = ''
AS
BEGIN
SELECT
[Code] .
What I want, is to be able to pass in a single value to filter the table, or if I pass in (at the moment a blank) for no filter to be applied to the table.
Is this a good way to accomplish that, or is there a better way? Also, down the line I'm probably going to want to have multiple filter items for a single filter, what would be the best way to implement that?
the code below works (this is only a quick dumbed down version of the actual code, it might not work 100% for all cases). Is it at all possible to exploit the functions that were added to SSQL since v. 2005 to simplify this code ?
In SSRS, a parameter allows the user to create a list of invoices (from CRM) to be ordered in any of the following ways the user prefers:
'Document Date (most recent date first)'
'Document Number (highest number first)'
'Document Date (most recent first) and Number'
'Document Number (lowest number first)'
The invoices have a (supposedly) sequential identity-generated number. However Accounting may want to set a different date than the creation date on some invoices. So there is no way the invoice numbers will be in the same sequence as the invoice dates.
So I just created the "sorting fields" - they appear as junk in the output dataset (just do not drop them in the SSRS tablix - they have to be part of the SELECT statement to be usable in the ORDER BY clause.
The code is:
DECLARE @ls_OrderBy varchar(80)
--'Document Number (highest number first)'
--'Customer and Document Date (most recent date first)'
--'Customer and Document Number (highest number first)'
--'Document Date (most recent first) and Number'

I'm trying to write a query to select various columns from 3 tables. In the where clause I use a set of conditions, but most important condition is that I only want to see all results from the different columns where the ph.ProdHeaderDossierCode contains at least 25 lines of processed hours. I tried this with group by and having, but I constant get error messages on all other columns that I want to see: "is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause". How can I make this so I can see all information I need?
Here is my code so far:
selectph.CalculatedTotalTime,
ph.ProdHeaderDossierCode,
ph.MachGrpCode,
ph.EmpId,
pd.PartCode
fromdbo.T_ProcessedHour ph,

I want to create the following scenario. I have a table that stores employees working on projects and their project hours by week, but now I also need a running total per week for each of those projects. For example take a look below:
EmployeeID, Project, Sunday, Monday, Tuesday,....Saturday, ProjectHours, TotalProjectHoursPerWeek(this is the column I am trying to derive), FiscalWeek
101, ProjectABC, 5,5,5,...5, 20, 40,25
102, ProjectXYZ 4,4,4,....4, 20 ,40,25
103,ProjectQWE, 2,2,2,...2, 8, 32,26
104, ProjectPOP, 6,6,6,...6, 24, 32,26
What I have tried so far:
Correlated Subquery:
SELECT EmployeeID,Project, Sunday, Monday,....Saturday, ProjectHours, SELECT(SUM(ProjectHours) FROM dbo.TableABC ap GROUP BY FiscalWeek),
FROM
dbo.TableABC a
I got this to work one time before, but now I am getting the following error:
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
I can't understand why I get 2 different results on running with a Bracket I get 'NULL' and without a bracket I get the declared variable value which is 'Noname'
Below is Query 1:
Declare @testvar char(20)
Set @testvar = 'noname'
Select @testvar= pub_name
FROM publishers
WHERE pub_id= '999'
Select @testvar
Out put of this query is 'Noname'
BUT when I type the same query in the following manner I get Null-------Please note that the only difference between this query below is I used brackets and Select in the Select@testvar statement
Declare @testvar char(20)
Set @testvar = 'noname'
Select @testvar=(Select pub_name
FROM publishers
WHERE pub_id= '999')
Select @testvar
I am writing a stored procedure and have a query where I create a variable from other table
Declare @Sem varchar (12) Null
@Decision varchar(1) Null
Select emplid,name, Semester
Decision1=(select * from tbldecision where reader=1)
Decision2=(select * from tbldecision where reader=2)
Where Semester=@Sem
And Decision1=@Decision
But I am getting error for Decision1 , Decision2. How can I do that.
Does anyone out there know if you can take a user like this domain1Username and without dropping it and recreating change it to domain2username. I am using Sql 7.
Thanks in advance

So, I kinda taught myself sql on the net in a couple of weeks... I've been practicing commands and what not with a database with a company I work with. Here's what I need some help with:
I'm creating a batch file that will connect to the sql server, and input a .sql in the batch file which launches the sql script to check to see if a store's data has come in or not, and if it hasn't, to launch the job to process that store. Now, after it launches the job, the only step for the job is to process what it can before it fails or completes, and most of the time it fails after 1-10 minutes. A big a variance. So my question is, how do I make it so that the script being called, waits for the job to finish before proceeding to the next command which checks a different store and launches another script?
If you want the script, I'll mod out some of the actual names for security purposes and post it for you guys. Any help is appreciated, and I've searched and hacked Google to get an answer, but nothing, so I decided to post this. Thanks!

Whilst digging about in the systables I noticed 2 curious things:
When creating an application that returned all tables, columns and fields I had to use sys.systables, and when returning the information from this view, I received two identical columns 1. myColumn of type sysname and 2. myColumn of type varchar. The point being, what is this column for, and why is it there, as it was quite annoying to note it when returning the dataset in my app.
My other point is, while checking out what I could do with sysname, I noted the xml type has a capacity of -1, whereas all other data types have a capacity between 2-8000. Could someone clarify this for me, as it seems a single xml document could be inserted upto 2gb.
