Implementing Functions & Aggregate Data: The applicants should be able to construct queries with the use of table-valued and scalar-valued functions; recognize the impact of function usage on query performance & WHERE clause; utilize built-in aggregate functions; recognize the variance between deterministic & non-deterministic functions; use date-related, system, and arithmetic functions.

Modifying Data: This requires that the learners develop skills in writing INSERT, DELETE, and UPDATE statements; constructing DML (Data Manipulation Language) statements utilizing OUTPUT statement; determining the results of DDL (Data Definition Language) statements on the provided tables & data; determining the specific statements that can be utilized to load data on a table based on structure & constraints.

Grouping& Pivoting Data using Queries: The candidates should be able to utilize windowing functions for grouping and ranking results of a query. They also need the relevant skills to distinguish between GROUP BY and windowing functions; construct intricate GROUP BY clauses with the use of GROUPING SETS, & CUBE; determine the effect of NULL values in UNPIVOT & PIVOT queries; construct UNPIVOT & PIVOT statements to return the anticipated results based on available data.

  • Programming Databases using Transact-SQL: 25-30%

The students are also required to know the following subtopics of this exam objective:

Creating Database Programmability Objects with the use of Transact SQL:The examinees should have the relevant skills in creating scalar-valued and table-valued user-defined functions, stored procedures, views, and triggers. This subtopic also requires competency in implementing input & output parameters in specific stored procedures; differentiating between deterministic & non-deterministic functions; identifying whether to use table-valued or scalar-valued functions; creating indexed views.

Implementing Error Handling & Transactions: This covers determining results of DDL statements based on the transaction control statements; generating error messages with THROW & RAISERROR; implementing TRY CATCH error handling with Transact SQL; implementing transaction control with error handling in stored procedures.

Implementing Data Types & NULLs: This requires the skills in evaluating results of conversions of data types; determining the appropriate data types for specific table columns or data elements; identifying the location of contained data type conversions in queries. It also covers the process of determining the appropriate results of functions and joins in the occurrence of NULL values and identifying the corresponding usage of COALESCE and ISNULL functions.

Conclusion
