If I install an instance with Windows Only authentication, and then change it to Mixed Mode, if I enable the sa login, the password has already been set. What is the default? If it's generated, how secure is it? Is the password generated? What algorithm is used for that?
I've been reading about the "table lock on bulk load" option and TABLOCK hint.
So my understanding is by default only row locks are taken out and other queries can read/write data while the bulk load is going on. However if you were doing parallel bulk loads with overlapping keys from a clustered index then they may block each other.
But if the option is enabled, you can do the parallel bulk loads without blocking because a table lock is taken out, however, other processes couldn't read/write the data until they're all done.
Is that the gist of it? I think I got confused by some misinformation. Don't all those row locks eventually likely escalate to a table lock anyway though?
I am tasked with correcting 600 SQL Server instances default settings. I would like to use powershell, if possible to loop thorough each named instances (I have a list) and apply the following settings. I also need to query the server for the installed memory and apply * 80% logic for maxmem, and look at the VCPU count and adjust the MAXDOP to that number.
USE MASTER GO EXEC sp_configure 'recovery interval (min)', '0'; RECONFIGURE WITH OVERRIDE; EXEC sp_configure 'allow updates', '0'; RECONFIGURE WITH OVERRIDE; EXEC sp_configure 'user connections', '0';
SELECT D_ID,C_ID,C_HIST_ID FROM @TABLE1 ACH WHERE ACH.C_ID= 71 AND ACH.C_HIST_ID IN (SELECT MAX(ACH1.C_HIST_ID) FROM @TABLE1 ACH1 WHERE ACH1.C_ID = ACH.C_ID AND ACH.D_ID = ACH1.D_ID ) ORDER BY C_HIST_ID
I have a table with some rows and columns what i want is i want to Show sum of particular column in the last row. This is my code.
SELECT DISTINCT Cluster.ClusterName, Gruppe.GruppeName, Arbeitspaket.ArbeitspaketName, BMWProjekt, AnzahlAP, Abgerechnet, InBearbeitung, Billanz FROM Bestellung INNER JOIN Cluster ON Bestellung.Cluster = Cluster.rowid INNER JOIN Arbeitspaket ON Bestellung.Arbeitspaket = Arbeitspaket.rowid INNER JOIN Gruppe ON Bestellung.Gruppe = Gruppe.rowid WHERE Projekt ="EA-284-Nxx" AND AnzahlAP <> 0 AND Abgerechnet is 1 AND InBearbeitung is NULL AND Billanz is NULL;
What I want to achieve is to get values from period1 till period04 and used the lasted value to code the value of accoutperiod, if value is from period1 then code it as 01, period2 as 02, period03 as 03 and period04 as 04. So the output should be like this
I have a database it is 50 gb with hundreds of columns. I would like to choose a certain column and convert the data in it to .csv or excel file. How can I do that I am very new to MSSQL...
I want to fetch max of Field2 if duplicate records in Field1 and rest of the values of field1 , below is the sample format.
Field1 Field2 Field3 Field4 32 375 abc-xyz A 32 379 xyz-efg A 55 405 abc-xyz B 55 407 xyz-efg B 132 908 abc-xyz C 132 999 xyz-efg C 152 800 abc-xyz D 152 850 xyz-efg D 155 900 abc-xyz E 156 925 abc-xyz F 157 935 abc-xyz G
I am trying to import 1 spreadsheet to a database table. I am using SSMS export import wizard to import spreadsheet. My goal is to import whole spreadsheet in one single column.
I have huge export files in a DB and i need to check if there are any datasets that have the same value in the first column, but a different in another one, via a query of course.
Like this:
ID IS NULL 1 1 2 1 3 0 1 0
The expected ID i get as a result of my query should be 1 in this case.
as per my client requirement we need subtotal of 'Amount' group by 'OrderNo'. column so am writing a select statement with WHERE condition and I would like to have another column called SUBTOTAL in the result set (select statement result) with subtotals for that order Number as below
I have the following SQL which i want to convert to a stored procedure having dynamic SQL to generate column numbers (1 to 52) for Sale_Week. Also, I want to call this stored procedure from Excel using VBA, passing 2 parameters to stored procedure in SQL Server e.g,
DECLARE @KPI nvarchar(MAX) = 'Sales Value with Innovation' DECLARE @Country nvarchar(MAX) = 'UK'
I want to grab the resultant pivoted table back into excel. how to do it?
USE [Database_ABC] GO
DECLARE @KPI nvarchar(MAX) = 'Sales Value with Innovation' DECLARE @Country nvarchar(MAX) = 'UK'
I am new to SQL Programming. I am learning the basics. I am trying to create a simple query like this -
SELECT Column_1, Column_2, Column_3, 10*Column_1 AS Column_4, 10*Column_2 AS Column_5,
-- I am not being able to understand how to do this particular step Column_1*Column_5 As Column_6
FROM Table_1 First 3 Columns are available within the Original Table_1 The Column_4 and Column_5 have been created by me, by doing some Calculations related to the original columns.
Now, when I try to do FURTHER CALCULATION on these newly created columns, then SQL Server does not allows that.
I was hoping that I will be able to use the Newly Created Columns 4 and 5 within this same query to do further more calculations, but that does not seems to be the case, or am I doing something wrong here ?
If I have to create a new column by the name of Column_6, which is actually a multiplication of Original Column_1 and Newly Created Column_5 "I tried this - Column_1*Column_5 As Column_6", then what is the possible solution for me ?
I have tried to present my problem in the simplest possible manner. The actual query has many original columns from Table_1 and many Calculated columns that are created by me. And now I have to do various calculations that involve making use of both these type of columns.
I would like to put a Clustered Index on a date column in a current heap, but one question/concern.This heap every month has thousands of rows deleted and even more added later. How much of an issue will this cause the Clustered Index as far as page splits? I was thinking Fill Factor of 70%.I would normally just test and still will on Dev box, but my Dev box is much smaller than production as far as power.
I am trying to implement the column encryption on one of the tables, have used the below link as the reference and got stuck at the last step.
[URL] ....
I have completed the following steps so far.
- CREATE MASTER KEY ENCRYPTION BY PASSWORD = ‘myStrongPassword’
- CREATE CERTIFICATE MyCertificateName WITH SUBJECT = 'A label for this certificate'
- CREATE SYMMETRIC KEY MySymmetricKeyName WITH IDENTITY_VALUE = 'a fairly secure name', ALGORITHM = AES_256,
[Code] .....
Example by using the function
EXEC OpenKeys
-- Encrypting SELECT Encrypt(myColumn) FROM myTable
-- Decrypting SELECT Decrypt(myColumn) FROM myTable
When I ran the last command :
-- Decrypting SELECT Decrypt(myColumn) FROM myTable
I get the following error :
Msg 257, Level 16, State 3, Line 2 Implicit conversion from data type nvarchar to varbinary is not allowed. Use the CONVERT function to run this query.
Where will I use the convert function, in decrypt function or in select statement?
I have four columns in my table, the first one is the identity column
col1 Col1 col2 col3
1 12 1 This is Test1 2 12 2 This is Test1 3 12 3 This is Test3 4 12 4 This is Test4 5 12 5 @@@@@
When, I see, @@@ sign in my col4, I need to restart the col3 from 1 again so it will look like this
col1 Col2 col3 col4
1 12 1 This is Test1 2 12 2 This is Test1 3 12 3 This is Test3 4 12 4 This is Test4 5 12 5 @@@@@ 6 12 1 This is another test1 7 12 2 This is another Test2
I tried with the following and result is coming for one month i.e. JUL but not with the second Month i.e Jun
SELECT 'Jul1' AS MON, [BNQ], [FNB], [RS] FROM (SELECT REVENUECODE, SUM(ROUND(((Jul/31)*30),0)) AS JUL FROM RM_USERBUDGETTBL WHERE USERNAME='rahul' AND FY=2015 GROUP BY REVENUECODE, USERNAME ) AS SourceTable PIVOT (SUM(JUL) FOR REVENUECODE IN ([BNQ], [FNB], [RS])) AS PivotTable
SQL server, by-mistake I updated values of a column in a database hosted online, is there any way undo the transaction. I didn't created any backup of the database. I read that still it can be recovered through the .ldf (log file) but unable to access it. Is there anyway to get access of the Log file or is there any way to recover the data.
I often use profiler as one tool to identify bad plans. The reads column gives me a good indication of excessive IO to dig into and correct if necessary. I often use it with Showplan so I can see what a query does, replicate it and fix it.
However I have just lost some faith in it. I am looking at a poorly performing query joining five tables. A parallel plan has been generated and one table is being scanned (in parallel) due to a missing index. This table had in excess of 4 million rows in it. The rest hitd indexes well. However the entire query generates ONLY 12 READS.
Once corrected, a single processor plan is used. This looks really efficient and uses 120 reads. That looks the right figure to me.
Clearly 12 reads is wrong. Does the profiler only display one thread of a parallel plan perhaps? Or something else?
