As we are mostly engaged in SQL Assignments, we come to the place where we found that there are lots of ldf files which occupies lots of the space on the DISK. To continue my work, I have to make a room on the same DISK. I found that there are lots of log files (LDF) on the disk which occupies more than 1 TB (1024 GB). This is the development server and I found and confirmed that we can have “Recovery Option” as “SIMPLE” too. The tricky part over here is, these databases are already created and Log file names are not same as database name. So, first of all I need to find out the database name to which I can make Recovery Option as Simple. Finally, I got following query which helps me to continue my assignment as follows:
Recently, I was assigned a job to create many DTSX packages. When I review the packages, I found those packages (Information flow) are moreover same. There is just a difference of Source file connection and destination SQL table which is different in each of the package. It might take couple of hours to create each of the package, but I wanted to get it done in few minutes. To achieve the same, I have looked up the DTSX code (XML) and updated as follows to achieve get it done efficiently and save some time.
Database Administrators might face this issue while certificate gets expired and database mirroring (Non domain database mirroring) gets disconnected as two servers, Primary and Secondary cannot communicate with each other. The error message can be found in Log as follows: Message Database Mirroring login attempt failed with error: 'Connection handshake failed. The certificate used by this endpoint was not found: Certificate expired. Use DBCC CHECKDB in master database to verify the metadata integrity of the endpoints. State 85.'. [CLIENT: xxx.xxx.xxx.xxx] In this post, We are going to review step by step process to resolve this issue by providing renew parameters with certificate configurations.
Now, let’s have a look at functionality of Merge Join Transformation task in SSIS. Benefit of using Merge join is, input datasets can be combination of any two datasets from (Excel file, XML file, OLEDB table, Flat file).Output can be result of INNER, LEFT Outer, or FULL Outer Join on both the datasets. Merge Join Transformation has two inputs and one output. It does not support an error output.
oday, I am going to give basic example of Lookup Transformation Task in SSIS. Lookup transformation performs lookup operation by joining data in input columns with reference table dataset columns.Lookup can be used to access addition information from the reference dataset based on the matching criteria Reference dataset can be OLEDB table, Excel file or cache file, or SQL query result.
Recently, found that people making much complex code to have an XML in application. I have found that they return result set in Table to the application and have applied code to convert that data table to XML by Asp. Net application. When I review the process, I have suggested that why don’t you use the XML feature of the application. They surprised the simple use of it and make their life easy. Let me have sample query to generate XML result sets in SQL Server database.
In my previous post, “XML Result sets with SQL Server”, we review to generate result sets in XML from SQL server. Then I got a comment from the team, to also have post to read XML in SQL Server.
As I mentioned earlier, PIVOT, in my earlier post, where we have reviewed the PIVOT with static columns. In practical world, we may need to have dynamic columns that needs to be displayed as below:
Recently, we have found that SQL SERVER is using most of the memory on the server, due to heavy queries are running on my different teams and it freezes the whole server. Due to time constraint team doesn’t have time to optimize those queries, so we have found a way to configure SQL SERVER to not to use all available memory. We have an option to configure how much memory can be used by SQL SERVER as below:
