Strategies to help you tackle Oracle Database SQL Certified Associate exam questions effectively
Allocate roughly 1-2 minutes per question. Flag difficult questions and return to them later.
Pay attention to keywords like 'MOST', 'LEAST', 'NOT', and 'EXCEPT' in questions.
Use elimination to narrow down choices. Often 1-2 options can be quickly ruled out.
Focus on understanding why answers are correct, not just memorizing facts.
Practice with real exam-style questions for Oracle Database SQL Certified Associate
Option A is correct because it accurately describes that a primary key uniquely identifies each record in its table and cannot contain NULL values, while a foreign key creates a relationship by referencing a primary key in another (or the same) table. Option B is incorrect because foreign keys are not required to be unique and can have duplicate values. Option C is incorrect because primary keys cannot contain NULL values, while foreign keys can. Option D is incorrect because foreign keys typically reference primary keys in different tables to establish relationships between tables.
Option B (ON DELETE CASCADE) is correct because it automatically deletes all child records in the related table when the parent record is deleted, preventing orphaned records. Option A (ON DELETE SET NULL) would set the foreign key values to NULL rather than deleting the child records. Options C and D would prevent the deletion of the parent record if child records exist, which doesn't solve the orphaned records problem.
Option C is correct because the WHERE clause is specifically used to filter rows based on specified conditions. In this case, it restricts the result set to only those rows where department_id equals 50. Option A is incorrect because the SELECT clause determines which columns are displayed, not which rows are returned. Option B is incorrect because the FROM clause specifies the table to query from, not which rows to return. Option D is incorrect because the WHERE clause filters rows during query execution, not after retrieval.
Option B is correct because the asterisk (*) is the SQL wildcard that represents all columns in a table. This is the standard SQL syntax for retrieving all columns. Option A is incorrect because ALL is not valid syntax for selecting all columns (though it exists as a keyword for other purposes). Option C is incorrect because COLUMNS is not a valid SQL keyword in this context. Option D is incorrect because the ampersand (&) is not used to select columns in SQL.
Option B is correct because the || operator in Oracle SQL is the concatenation operator, which combines multiple strings or column values into a single string. In this case, it concatenates the product_name value, the literal string ' - ', and the category value. Option A is incorrect because || is not a logical OR operator in SQL (OR is used for that). Option C is incorrect because column aliases are created using AS or by simply providing a name after the expression. Option D is incorrect because equality comparison uses the = operator.
