Which query executes correctly in PROC FEDSQL?

• A. proc fedsql; select EmployeeID, Name, Salary, Department from orion.employee where = "Management"; quit;
• B. proc fedsql; select EmployeeID, Name, Salary, Department from orion.employee where = 'Management'; quit;
• C. proc fedsql; select * from orion.employee where Department = "Management"; quit;
• D. proc fedsql; select EmployeeID, Name from orion.employee where Name = 'Smith' or Name = 'Johnson'; quit;

Answer: (D)

The query that executes correctly in PROC FEDSQL is recognized for its proper syntax and adherence to SQL standards within the context of the SAS environment. In this case, the selection of EmployeeID and Name from the orion.employee table, combined with a condition that specifies two distinct names, demonstrates the ability to filter data effectively. The use of logical operators like 'or' to include multiple conditions is particularly important for retrieving records that meet any of the specified criteria. By correctly structuring the query with the appropriate syntax, including the complete WHERE clause, it enables the SQL engine to filter records efficiently. This query effectively applies the logical operation to retrieve rows where the Name is either 'Smith' or 'Johnson', showcasing PROC FEDSQL's functionality in handling conditional statements. The other options fail to execute correctly primarily due to syntax errors, such as missing comparison operators, incorrect use of quotation marks for string literals, or incomplete where clauses. These mistakes prevent those queries from being valid in a SQL context and thus lead to execution errors.
