🎯 Database-Specific Examples

Try these examples for different database vendors:

🔶 Oracle Specific

SELECT employee_id, 
       ROWNUM as row_number,
       SYSDATE as current_date
FROM employees 
WHERE ROWNUM <= 10;

🔵 SQL Server Specific

SELECT TOP 10 
       employee_id,
       GETDATE() as current_date
FROM employees 
ORDER BY hire_date DESC;

🟢 MySQL Specific

SELECT employee_id,
       NOW() as current_timestamp,
       LIMIT 10
FROM employees 
ORDER BY hire_date DESC
LIMIT 10;

🐘 PostgreSQL Specific

SELECT employee_id,
       CURRENT_TIMESTAMP,
       age(birth_date) as employee_age
FROM employees 
LIMIT 10;

❄️ Snowflake Specific

SELECT employee_id,
       CURRENT_TIMESTAMP(),
       DATEDIFF('year', birth_date, CURRENT_DATE()) as age
FROM employees 
QUALIFY ROW_NUMBER() OVER (ORDER BY hire_date) <= 10;

📊 BigQuery Specific

SELECT employee_id,
       CURRENT_DATETIME() as current_time,
       DATE_DIFF(CURRENT_DATE(), birth_date, YEAR) as age
FROM employees 
ORDER BY hire_date DESC
LIMIT 10;
