You have a trigger named CheckTriggerCreation that runs when a user attempts to create a trigger. The CheckTriggerCreation trigger was created with the ENCRYPTION option and additional proprietary business logic.
You need to prevent users from running the ALTER and DROP statements or the sp_tableoption stored procedure.
Which three Transact-SQL segments should you use to develop the solution? To answer, move the appropriate Transact-SQL segments from the list of Transact-SQL segments to the answer area and arrange them in the correct order.
You are developing an application that connects to a database.
The application runs the following jobs:
The READ_COMMITTED_SNAPSHOT database option is set to OFF, and auto-content is set to ON. Within the stored procedures, no explicit transactions are defined.
If JobB starts before JobA, it can finish in seconds. If JobA starts first, JobB takes a long time to complete.
You need to use Microsoft SQL Server Profiler to determine whether the blocking that you observe in JobB is caused by locks acquired by JobA.
Which trace event class in the Locks event category should you use?
You are developing a database reporting solution for a table that contains 900 million rows and is 103 GB.
The table is updated thousands of times a day, but data is not deleted.
The SELECT statements vary in the number of columns used and the amount of rows retrieved.
You need to reduce the amount of time it takes to retrieve data from the table. The must prevent data duplication.
Which indexing strategy should you use?
Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
You have a database that contains the following tables: BlogCategory, BlogEntry, ProductReview, Product, and SalesPerson. The tables were created using the following Transact SQL statements:
You must modify the ProductReview Table to meet the following requirements:
* The table must reference the ProductID column in the Product table
* Existing records in the ProductReview table must not be validated with the Product table.
* Deleting records in the Product table must not be allowed if records are referenced by the ProductReview table.
* Changes to records in the Product table must propagate to the ProductReview table.
You also have the following database tables: Order, ProductTypes, and SalesHistory, The transact-SQL statements for these tables are not available.
You must modify the Orders table to meet the following requirements:
* Create new rows in the table without granting INSERT permissions to the table.
* Notify the sales person who places an order whether or not the order was completed.
You must add the following constraints to the SalesHistory table:
* a constraint on the SaleID column that allows the field to be used as a record identifier
* a constant that uses the ProductID column to reference the Product column of the ProductTypes table
* a constraint on the CategoryID column that allows one row with a null value in the column
* a constraint that limits the SalePrice column to values greater than four Finance department users must be able to retrieve data from the SalesHistory table for sales persons where the value of the SalesYTD column is above a certain threshold.
You plan to create a memory-optimized table named SalesOrder. The table must meet the following requirements:
* The table must hold 10 million unique sales orders.
* The table must use checkpoints to minimize I/O operations and must not use transaction logging.
* Data loss is acceptable.
Performance for queries against the SalesOrder table that use Where clauses with exact equality operations must be optimized.
You need to create a stored procedure named spDeleteCategory to delete records in the database. The stored procedure must meet the following requirements:
* Delete records in both the BlogEntry and BlogCategory tables where CategoryId equals parameter
@CategoryId.
* Avoid locking the entire table when deleting records from the BlogCategory table.
* If an error occurs during a delete operation on either table, all changes must be rolled back, otherwise all changes should be committed.
How should you complete the procedure? To answer, select the appropriate Transact-SQL segments in the answer area.
You create a database table named FactSales by running the following Transact-SQL statements:
You must optimize the indexes without making changes to the ix_FactSales_EmployeeKey index.
You need to implement a columnstore index for the table.
How should you complete the Transact-SQL code? To answer, select the appropriate Transact-SQL segments in the answer area.
NOTE: Each correct selection is worth one point.
