SQL 2012 :: Query With Three Tables?
Jul 22, 2015I currently have a query that uses three tables [Table1, Table2, Table3]. Each table only has two columns: Group and something else. I want a query that gives me the group and those three something else.
Table1: Group and Info1
Table2: Group and Info2
Table3: Group and Info3
Query: Group, Info1, Info2, Info3
The groups never repeat in a single table.
However, the groups are not identical in every table. I want the groups to never repeat twice: All the groups should appear if they are there at least once in one of the table, and provide Info1, Info2, Info3 (blank if it's not there in its table, filled if it is).
That should be a fairly simple query, I just can't seem to make it work so groups don't repeat.
Little visual example.
Table1: Group - Info1
1 - a
2 - b
4 - c
5 - d
Table2: Group - Info2
1- aa
3- bb
4- cc
Table3: Group - Info3
5- aaa
The query would give me this:
1 - a - aa - ""
2 - b - "" - ""
3 - "" - bb - ""
4 - c - cc - ""
5 - d - "" - aaa
SQL 2012 :: Configuring Alert For Low Memory?
Oct 1, 2015configuring sql alert for low sql memory.
I have configured the memory for sql server as below
min : 512 MB
Max :13500 MB
Total RAM on the server is 16GB
I want to receive email from sql server informing that sql server is running on low memory ( less than 200 MB free) so that I do not get out of memory issues and the sql server continues to run without fail.
Transact SQL :: XML Not Using Proper Index?
Aug 26, 2015I have two xml queries that take long: the 1st query takes about 5 minutes (returns 700 rows) and the 2nd query takes about 10 minutes (returns 4 rows). The total rows in the table is about 2 million. There are three secondary indexes: Property, Value and Path in addition to the clustered index on CardID and Primary XML index. Here is the table definition:
CREATE TABLE [dbo].[Cards]
(
[CardId] [int] NOT NULL,
[Card] [xml] NOT NULL,
CONSTRAINT [PK_dbo_Cards_CardId] PRIMARY KEY CLUSTERED
([CardId] ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
[code]...
Looking at the execution plan, the query uses the Primary XML Index even if I add any of the secondary xml indexes. My question is why does not the optimizer use the Property 2ndary index instead of the Primary XML Index? Microsoft recommends that creating a Property index for Value() method of the xml datatype would work to provide a performance benefit. What would be another alternative to make the query run faster?
SQL Server 2012 :: Alphanumeric Range Grouping?
Feb 25, 2015I am having some difficulty getting a query to output an alpha numeric range grouping.
I have this data set:
Despatch_id Sample_ID
MIR00831 MCR0005752
MIR00831 MCR0005753
MIR00831 MCR0005754
MIR00831 MCR0005755
MIR00831 MCR0005756
MIR00831 MCR0005757
[code]....
Output:
DESPATCH_ID SAMPLE_ID_FROM SAMPLE_ID_TO
MIR00831 MCR0005752 MCR0005762
MIR00831 MCR0005803 MCR0005806
MIR00831 MCR0005808 MCR0005813
They need to be grouped by range specific to the alpha numeric part, which can vary within the same despatch. I was thinking of using a row over partition after splitting the numeric and alpha part and to check if they are consecutive and build the range. But I am thinking that this approach is an overkill and there may be a better way to achieve this in SQL 2012.
I have included the create table scripts and example data below:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[SAMPLE_TABLE](
[DESPATCH_ID] [nvarchar](30) NOT NULL,
[SAMPLE_ID] [nvarchar](30) NOT NULL
[code]....
Setting Up Directories - Data Paths In Server?
Aug 4, 2015I'm curious if there's a "best practice" for setting up the data directories MS SQL will use for each operation? I've allocated independent disks for things like C: (OS), E: (DATA), etc etc etc but I'm not familiar w/ MS SQL to understand how DBA's commonly configure the folders under each unique disk for things like DATA, LOGS, BACKUP, INDEXES, and TEMPDB. Should I have an identically name folder as show below in my example?
You can see I've just mirrored the drive name to a new folder under the partition so data is being written to: F:DATA and E:LOGS. Is this considered correct / good practice? I assume naming the folder in each mount point to whatever I logically called the drive is correct but if I should change how I configure my drive paths above. I'm trying to learn common good SQL Server practices and while I work on properly installing SQL Server 2012/2014, I want to make sure I configure my partition names SQL will utilize correctly.
Reporting Services :: SSRS - IIF / Switch / Replace Multiple Conditions In A Field
Nov 18, 2015Have a nvarchar column in ms sql that, based on user input, may or may not have a carriage return and a line break together (CHR(13)&CHR(10)), just a carriage return (CHR(13)), just a line break (CHR(10)). In using that column in ssrs, I need to find if any of the above exist and replace them with the string "x0Dx0A", "x0D", or "x0A" respectively.
I'm getting lost in this expression:
=SWITCH
( (InStr(Fields!Info.Value, CHR(13)&CHR(10) > 0, REPLACE(Fields!Info.Value, CHR(13)&CHR(10)), "x0Dx0A")), (InStr(Fields!Info.Value, CHR(13) > 0, REPLACE(Fields!Info.Value, CHR(13)), "x0D")), (InStr(Fields!Info.Value, CHR(10)
> 0, REPLACE(Fields!Info.Value, CHR(10)), "x0A")) )
Error is:
System.Web.Services.Protocols.SoapException: The Value expression for the textrun ‘Info.Paragraphs[0].TextRuns[0]’ contains an error: [BC30455] Argument not specified for parameter 'Replacement' of 'Public Function Replace(Expression As String, Find As String,

SQL Server 2012 :: Extract Old Record Value
Jun 3, 2014I have a 2table like
create table test1
(col1 identity(1,1),
col2 varchar(20)
)
create table test2
(old int,
new int)
Existing record in test1 table
(1,'test')
Now I want to insert a new record into test1 and then capture the old and new identity columsn in test 2 table
i.e. after insert test1 table will be
1,test
2,test
and test2 table will be like
1,2 -- old and new identity columns are captured during insert and stored in test2 table.
If the repeat the process again test2 table will be like
1, test
2,test
3, test
and test2 table will be
2,3 --- test2 table will always have only one record. old records will be deleted.
Using output clause i can get the new identity value.. but how can i get the old identity value and insert that into test2 table..
I am not willing to do a self join after the record is inserted into test2. I wanted to get the old ident value during insert of new ident value.
Integration Services :: Integrate Server With Sybase

View 2 RepliesTransact SQL :: How To Get Value Of A Particular Field From XML Data
Nov 6, 2015We are running the following querry which insert data row from an XML source
INSERT INTO End_ReelProcessValue
(LineId
,ReelHist_id
,Variable_tagName
,ProcessMeasure
)
[Code] ....
From that querry, I need to store in a variable the Value of a particular XML entry in order to store it in an other table.The XML parsing is based on the following lines :
[Variable_Tagname] CHAR(50) '@Name',
[ProcessMeasure] NVARCHAR(254) '@Value'
What I need is that if the [Variable Tagname] issue from entry @Name is equal to the string "Quality", then I need to store its value to a variable.Then an other querry will use that variable to insert it to an other table.
How can I retrieve that particular record ?
Comma Separated To Columns

Transact SQL :: Create A Query From Two Physical Servers?
Oct 15, 2015I am trying to create a query that will get data from two diffrent SQL servers. I am trying to link the two servers by using the sp_addlinkedserver. This is the code I use:
USE master;
GO
EXEC sp_addlinkedserver
N'SC00SRVERP501R1',
N'SQL Server';
GO
and it executes successfully. But when I try to run my query I get the error message "Login failed for user 'NT AUTHORITYANONYMOUS LOGON'."As far as I understand I need to provide some credentials to the linked server, but how do I do that ?
Changing Output Of Select
Feb 18, 2015I have a table: it contains a list of data belonging to a name, however the field 'name' defines the source.
name |field1 |field1data |
test1 |in |123
test1 |out |345
test2 |in |123
test2 |out |456
test3 |in |123
test3 |out |456
I'm trying to get the data out of the database in a columed format, I would be quite comfortable doing this if 'in' and 'out' where there own field. The output i'm trying to get is:
name |data |data |
test1 |123 |456
test2 |123 |456
test3 |123 |456
in an ideal world i'd like to be able to have the header the name of the field data - eg
name |in |out |
test1 |123 |456
test2 |123 |456
test3 |123 |456
I can use - select name,field1data from table where field1 in ("in","out")but this returns each piece of data as a new row - eg:
name |field1data |
test1 |123
test1 |456
test2 |123
test2 |456
test3 |123
test3 |456
SQL 2012 :: Estimate Row Count - WHERE Clause Of Statement
Oct 16, 2014How SQL calculates the estimated row count when < or > are used in the WHERE clause of a statement. For example:-
WHERE Created_Datetime_utc > CONVERT(DATETIME,'2014-10-14 10:00:00',102)
I know how the estimated number of rows are calculated when an = is used but I've been googling and cannot find anything about < and >.
