Is there a difference in the following: DECLARE @T1 VARCHAR(50);
SET @T1 = (SELECT TOP(1) Col1 FROM MyTable); -- define variable first way
SELECT TOP(1) @t1 = Col1 FROM MyTable; --
define variable second wayI did a quick test and not finding a difference, however I was told that if nothing is returned by the query the result would be different and that the first way is better.
I am really puzzled by an apparent difference between table index key column order and its statistics order. I was under understanding that index statistics mirror index definition. However, in my db 2470 index ordinal definitions match statistics definition but 66 do not. I also can reproduce such discrepancy in 2008 R2, 2012 and 2014.
As per definition,
stats_column_id
int
1-based ordinal within set of stats columns
This script duplicates this for me.
BEGIN TRAN
GO
use tempdb
GO
CREATE TABLE [dbo].[ItemProperties](
[itmID] [int] NOT NULL,
[cpID] [smallint] NOT NULL,
[ipuID] [tinyint] NOT NULL,
[Code] ....
The result I get is this:
object_id stats_name
stats_column_list
1525580473 PK_ItemProperties_itmID_ipuID_cpID itmID, cpID, ipuID,
and
object_id index_name
index_column_list
1525580473 PK_ItemProperties_itmID_ipuID_cpID itmID, ipuID, cpID,
Also a query I used to discover this in my db is:
WITH stat AS
(
SELECT
s.object_id
,s.name as stats_name
,(
SELECT
c.name + ', ' as [data()]
FROM sys.stats_columns as sc
[Code] .....
I've table and data as follow,
declare @tAccount table
(
isLocked bit,
LastLockoutDate datetime,
currentDte dateTime
)
insert into @tAccount values('true','2014-04-26 16:11:25.337',getdate())
Let's say, current data as follow,
isLocked| LastLockoutDate| currentDte
12014-04-26 16:11:25.3372014-04-27 01:45:15.053
How to get different in minutes between currentDate and LastLockoutDate? Mean, currentDate - LastLockoutDate.
I have two similar tables in different database and need to make query to select only the data from the first table that is not available in the second table and there is no unique record for each record , but each row is having different records for example:
CREATE TABLE table1(
[PNR] [nvarchar](10) NOT NULL,
[Tkt_Number] [nvarchar](10) NOT NULL,
[DepaCityName] [nvarchar](50) NULL,
[ArriCityCode] [nvarchar](3) NULL,
[Code] ....
Output should be like this
PNR | TKT_NUMBER | DEPACITYNAME | ARRCITYCODE | NAME
fdf44 12669 Sah DXB lamees
I'm trying to get the difference between the two times in minutes with the seconds rounded up or down
As an example the difference in the times:
1900-01-01 09:27:49.000, 1900-01-01 09:32:28.000 is 279 seconds which is 4.65 minutes,
using
select
cast(round(datediff(second, convert(datetime, '1900-01-01 09:27:49.000'), convert(datetime, '1900-01-01 09:32:28.000')) / 60, 2) as numeric(18,2))
I am receiving the value 4.00 instead of 5 which I would like 4.65 to round to. How can I get the difference in seconds to round to the minute ?
select datediff(wk, '2015-01-11', '2015-01-19') returns 1 (shouldn't it return 2?)
select datediff(wk, '2015-01-10', '2015-01-19') returns 2
I have a job that runs in sql 2008r2 that declares a value to a variable. This variable is passed to a function. I need to include more values in and am unsure how to do this. @InCo could be 4,5,6,or 7.
See below.
Declare @ReportDateIN [datetime]=GETDATE(),
@InCo varchar(max) = 4,
@OutCo varchar(max) = 8,
@IncludeDetailIN [int]= 1,
@IncludeReleasedIN [int]= 1,
@IncludeHoldingIN [int]= 1
[Code] .....
declare @filename varchar(255),
@path varchar(255),
@sql varchar(8000),
@sql3 varchar(8000),
[Code].....
i need to set a Apostrophe in front of dir and at the end
I am trying to do the following:
DECLARE @MinBoundary DateTime, @s nvarchar(max)
declare @DBName sysname, @TableName sysname
select @DBName = 'MyDB', @TableName = 'MyTable'
select @s = '
SELECT Convert(DateTime, MIN(PRV.value))
[Code] ...
It works if I print @s query and run it this way, so the query is correct):
DECLARE @MinBoundary DateTime
SELECT @MinBoundary = Convert(DateTime, MIN(PRV.value))
FROM sys.partition_functions AS PF
JOIN sys.partition_parameters AS PP
ON PF.function_id = PP.function_id
[Code] ....
I'm going around in circles trying to visualise what's happening in this code,
declare @ReturnValue int, @ProcessFlag int
exec @ReturnValue=spGetProcessFlag @ProcessFlag output
select @ReturnValue as ReturnValue, @ProcessFlag as ProcessFlag
I get the feeling that the code runs spGetProcessFlag, and assigns the value to either @ReturnValue or @ProcessFlag.
By the way - next task is to direct SSIS whether to fail package or continue running.
I am reviewing some code we have inherited (riddled with multiple nested cursors) and in the process of re-writing some of the code. I came across this and it has me puzzled.
As I understand it, if you declare a variable and then try to re-declare a variable of the same name an error is generated. If I do this inside a While loop this does not seem to be the case. What ever is assigned is kept and just added to (in the case of a table variable)
I understand things are in scope for the batch currently running but I would expect an error to return (example 1 and 2)
--Table var declaration in loop
SET NOCOUNT ON
DECLARE @looper INT = 0
WHILE @looper <= 10
BEGIN
DECLARE @ATable TABLE ( somenumber INT )
[Code] ....
I am using a cursor (i know - but this is actually something that is a procedural loop).
So effectively i have a table of names of stored procedures. I now have a store proc that loops around these procs and runs each one in order.
Now i am thinking i would like to be able to set the table it loops around in a variable at the start - is it possible to do this? So effectively use a tablename in a variable to use in the sql to define a cursor?
The below cursor is giving an error
DECLARE @Table_Name NVARCHAR(MAX) ,
@Field_Name NVARCHAR(MAX) ,
@Document_Type NVARCHAR(MAX)
DECLARE @SOPCursor AS CURSOR;
SET
@SOPCursor = CURSOR FOR
[Code] ....
The @Table_Name variable is declared, If I replace the delete statement (DELETE FROM @Table_Name ) with (PRINT @table_name) it works and print the table names.
Why does the delete statement give an error ?
declare @user varchar(30) = ''
if(@user is not null or @user <> '')
BEGIN
print 'I am not empty'
END
ELSE
BEGIN
print 'I am empty'
ENd
The output should be 'i am empty' but when i execute this i am getting ' i am not empty'. even i did browse through but i don't find the difference in my logic.
I have created dynamic sql to declare variables based on columns from the table and i set values to those variable now here is the issue . i want to check the variable values how do i do that dynamically
drop table test
create table test
(
id varchar(10) not null,
col1 varchar(10) ,
col2 varchar(10)
[Code] .....
Now my next step is verify if the variable is blank or not how do i do that ?
How do i verify all of the columns one after the other .
I am after the statement like this dynamically
-- IF NOT (@col1 = '') THEN set @SQL = @SQL + '[col1] = ' + @col1 + ' '
--IF NOT (@col2 = '') THEN set @SQL = @SQL + '[col2] = ' + @col2 + ' '
I need to check if the columns are blank or not dynamically as i do not want to hard code the column names there.
i have a monthly production script that requires two forms of the prior month's date.'yyyymm' or '201411' and 'yyyy-mm-dd' or '2014-11-01'. The second date must have a day value of '1'. I have to use these date values in my script a half dozen times. Ive tried to declare two variables to accomodate but i can not get them correct.
I can execute the following:
SELECT LEFT(CONVERT(varchar, DATEADD(MONTH,-1,GetDate()),112),6)
---------------------------
201411
When I try this as a declared variable:
DECLARE @RPT_DTA VARCHAR
SET @RPT_DTA = CONVERT(varchar, DATEADD(MONTH,-1,GetDate()),112)
SELECT @RPT_DTA
--------------------------
2
DECLARE @RPT_DTB VARCHAR
SET @RPT_DTB = DATEPART(YEAR,DATEADD(MONTH,-1,GetDate())) + DATEPART(month,DATEADD(MONTH,-1,GetDate()))
SELECT @RPT_DTB
-----------------------------

I need to calculate total discount on item in case when user has several discounts, and they each apply on discounted amount. I thought to have something like:
DECLARE @Disc float
SET @Disc = 0
SELECT @Disc = @Disc + (100 - @Disc) * Disc / 100
FROM UserDiscounts
WHERE UserID = 123
but, seems, it does not work.
Looking for single query without any loops?

I am using xml schema that is like this:
<DetailRows>
<DetailRow>
<MonthNumber></MonthNumber>
<Amount></Amount>
</DetailRow>
</DetailRows>If my variable contains following xml document as un-typed xml

I have two tables. Table 1 has column "job", table 2 has column "job" and column "item". In table table 2 there are multiple "items" for each "job"
I would like to insert all of the "items" into table 1, based on a join table1.job = table2.job
I'm trying to create a Character string so that I can execute dynamic SQL.
The date is going to change.
DECLARE @Select VARCHAR (50)
DECLARE @SQLQuery VARCHAR (500)
DECLARE @PreSelect CHAR (1)
DECLARE @CurrentDate Date
SET @SQLQuery = 'SELECT CAST(CAE_RDB_ENTRY_DATE as Date), *
FROM OPENQUERY(LS_RDB_DWH,'
SET @PreSelect = '''
SELECT @Preselect AS PreSelect
If I try this statement which what I really want. I would like to include the Quote with the Select.:
SET @Select = ''SELECT * FROM RDB_DWH_ASSOCIATE_ENTITY WHERE CAE_RDB_ENTRY_DATE >''
I get the following error:
Invalid object name 'RDB_DWH_ASSOCIATE_ENTITY'.
So I have the following column named String in a table:
<key>Children</key><integer>2</integer>
This of course can vary for the different records. What's the best way to replace the 2 with the contents of my variable with TSQL?
declare @children int
set @children = 4
I want to do something like this:
SELECT <key>Children</key><integer>@children</integer>
Row Value :
Fiscal Year: 2016(
)Budget Scenario: Main Budget (0+12)(
)Forecast Scenario: Jun (0+12) Forecast(
)Department: 400 - New York(
)YTD Period: Jun
and I need to extract 400 only... substring fails because the length of the Scenario, Forecast etc differs.
Should I just go for charindex on break() or is there a another way ?
I have a stored procedure that returns XML using FOR XML Explicit. I need to use the output of this procedure in another procedure, and modify the xml output before it is saved somewhere.
Say StoredProc1 is the one returning xml output and StoredProc2 needs to consume the output of StoredProc1
I declared a nvarchar(max) variable and trying to saved the result of StoredProc1
Declare @xml nvarchar(max)
EXEC @xml = StoredProc1 @Id
This doesn't work as expected as @xml doesn't get any value assigned or rather I would say
EXEC @xml = StoredProc1 @Id
outputs the entire xml whereas it should just save the xml in a variable.
I want to add the result of a Select statement inside a parameter, not too sure how to pull this off, but here it is...

Is it possible to use a variable to specify the filegroup in the ALTER/CREATE PARTITION SCHEME command?
I want the partition scheme to use the default filegroup for ALTER and CREATE PARTITION SCHEME. At the time the script is created, I don't know the default filegroup in the database.
My code:
declare @fileGroupName VARCHAR(50) = (select top 1 name from
sys.filegroups where is_default = 1)
ALTER PARTITION SCHEME MyScheme NEXT USED @fileGroupName
Is failing:
Incorrect syntax near '@fileGroupName'.
Q: Is it possible to use a variable for the filegroup in the ALTER/CREATE commands? Is so, what is the correct syntax?
Q: If using a variable is not possible, is there another way to specify the default filegroup?
which is more efficient...which takes less memory...how is the memory allocation done for both the types.

I managed to transpose rows into columns.
;WITH
ctePreAgg AS
(
select top 500 act_reference "ActivityRef",
row_number() over (partition by act_reference order by act_reference) as rowno,
t3.s_initials "Initials"
from mytablestuff
order by act_reference
[code]...
But what I would love to do next is take each of the above rows - and return the initials either in one column with all the nulls and duplicate values removed, separated by a comma ..
ref, initials
Ag-4xYS
Ag-6xYS,BL
Ap-1xKW
At-2x SAS,CW
At-3x SAS,CW
OR the above but using variable number of columns based on the maximum number of different initials for each row.this is not strictly required, but maybe neater for further work on the view
ref, init1,init2
Ag-4xYS
Ag-6xYS,BL
Ap-1xKW
At-2x SAS,CW
At-3x SAS,CW
