MySQL AND

The AND operator is used to combine two or more conditions in a SQL query. It returns records where all the specified conditions are true.

Example with Tamil Kings

1. Using AND with Multiple Conditions

SELECT * FROM tamil_kings_auto_increment
WHERE reign_period = '985–1014 CE' AND king_name = 'Raja Raja Chola';

Code Explanation: This query selects records from the tamil_kings_auto_increment table where the reign_period is '985–1014 CE' and the king_name is 'Raja Raja Chola'. Both conditions must be true for the record to be selected.

Best Practices

  • Use AND when multiple conditions must all be true.
  • Ensure proper indexing on columns used in the conditions to optimize query performance.

Key Takeaways

  • The AND operator returns records that satisfy all specified conditions.
  • It is commonly used in WHERE clauses to filter data effectively.
