Answers to SQL/SSIS Developer interview questions

To delete duplicate records in a table, you can use the DELETE statement with a self-join or a subquery.
The number of indexes in a table can be determined by querying the system catalog views or using database management tools.
A sequence is an object in SQL Server that generates a sequence of numeric values. It can be used to generate unique identifiers while inserting rows into a table.
To use a sequence while inserting rows, you can include the NEXT VALUE FOR function in the INSERT statement.
LPAD and RPAD are functions in SQL Server that pad a string with a specified character on the left or right side.
An execution plan is a detailed blueprint of how SQL Server will execute a query. It can be obtained using the SQL Server Management Studio or by enabling the actual execution plan option.
The performance of sequence containers in an SSIS package depends on various factors such as the tasks within each container, data flow, and system resources.
Event handlers in SSIS are workflows that are triggered by specific events, such as task completion or error occurrence. They allow you to perform additional actions based on these events.
To pick up files from a folder with the latest date in SSIS, you can use a script task to retrieve the file names and sort them based on the date.
Event logging in SSIS involves capturing and recording events that occur during package execution. This can be done using logging providers and configuring the desired events to be logged.
Dynamic configuration in SSIS allows you to store package configurations in external sources such as XML files or SQL Server tables. This provides flexibility in changing package settings without modifying the package itself.
Late arriving dimensions in SSIS are handled by using techniques such as surrogate keys, slowly changing dimensions, or using a separate process to update the dimension table.
Incremental load in SSIS involves loading only the new or modified data from the source into the destination, rather than reloading the entire dataset.
