Answer: QUESTION 56 You have a database named DBl that contains the following tables: Customer, CustomerToAccountBridge, and CustomerDetails. The three tables are part of the Sales schema. The database also contains a schema named Website. You create the Customer table by running the following Transact-SOL statement: The value of the CustomerStatus column is equal to one for active customers. The value of the Account1Status and Account2Status columns are equal to one for active accounts. The following table displays selected columns and rows from the Customer table.

Only allow updates through the views that adhere to the view filter. You have the following stored procedures: spDeleteCustAcctRelationship and spUpdateCustomerSummary. The spUpdateCustomerSummary stored procedure was created by running the following Transacr-SQL statement: The following table displays a selected columns and rows from the Customer table. The value of the CustomerStatus column is equal to one for active customers. The value of the Account1Status and Account2Status columns are equal to one for active accounts. You run the spUpdateCustomerSummary stored procedure to make changes to customer account summaries. Other stored procedures call the spDeleteCustAcctRelationship to delete records from the CustomerToAccountBridge table. Users report that the following SELECT statement statement takes a long time to complete: You need to create an index that meets the following requirements: 1. Improve the performance of the SELECT statement. 2. requires minimum index key size. 3. Only contains active customers. 4. Makes no change to the existing primary key. 5.

To answer, move the appropriate code blocks from the list of code blocks to the answer area and arrange them in the correct order. Answer: Answer correct: create non custered index.... on Customer(CreatedDate) Where CustomerStatus<>1 QUESTION 58 You have a database named DB1. The database does not have a memory optimized filegroup. You create a table by running the following Transact-SOL statement: The table is currently used for OLTP workloads. The analytics user group needs to perform real-time operational analytics that scan most of the records in the table to aggregate on a number of columns. You need to add the most efficient index to support the analytics workload without changing the OLTP application. What should you do? A. Create a clustered index on the table. B. Create a nonclustered index on the table. C. Create a nonclustered filtered index on the table. D. Create a clustered column store index on the table. E.

Only allow updates through the views that adhere to the view filter. You have the following stored procedures: spDeleteCustAcctRelationship and spUpdateCustomerSummary. The spUpdateCustomerSummary stored procedure was created by running the following Transacr-SQL statement: You run the spUpdateCustomerSummary stored procedure to make changes to customer account summaries. Other stored procedures call the spDeleteCustAcctRelationship to delete records from the CustomerToAccountBridge table. When a procedure calls spDeleteCustAcctRelationship, if the calling stored procedures has already started an active transaction, all the detections made by the spDeleteCustAccRelationship stored procedure must be committed by the caller; otherwise changes must be committed within the spDeleteCustAcctRelationship stored procedure. If any error occurs during the delete operation, only the deletes made by the soDeleteCustACCTRelationships stored procedure must be rolled back and the status must be updated. You need to complete the stored procedure to ensure all the requirements are met. How should you complete the procedure? To answer, drag the Transact-SOL segments to the correct location. Each transact-SOL segment may be used once, more than once or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point.
