Code coverage
What is code coverage?
Basic coverage criteria
- Function coverage – has each function (or subroutine) in the program been called?
- Statement coverage – has each statement in the program been executed?
- Edge coverage – has every edge in the control-flow graph been executed?
- Branch coverage – has each branch (also called the DD-path) of each control structure (such as in if and case statements) been executed? For example, given an if statement, have both the true and false branches been executed? (This is a subset of edge coverage.)
- Condition coverage – has each Boolean sub-expression evaluated both to true and false? (Also called predicate coverage.)

SQL Execution Order
Secret To Optimizing SQL Queries – Understand The SQL Execution Order
- Execution Plan
- Search Argument Able (SARGABLE)
- Index Scan (bigTransactionalHistory)
- Stream Aggregare (Aggregate)
- Parallelism (Repartition Streams)
- Stream Aggregare (Aggregate)
- Clustered Index Scan (bigProduct)
- Parallelsim (Repartition Streams)
- Merge Join (Inner Join)
- Parallelism (Gather Streams)
To write sargable queries
- Avoid using functions or calculations on indexed columns in the WHERE clause
- Use direct comparisons when possible, instead of wrapping the column in a function
- If we need to use a function on a column, consider creating a computed column or a function-based index, if the database system supports it
