The Select statement is used to retrieve data from single or multiple tables:
SELECT field 1, field 2, field 3 from table_name [WHERE Clause] [GROUP BY {col_name }] [HAVING where_condition] [ORDER BY {col_name} {ASC | DESC}, ...] [LIMIT{OFFSET M}{LIMIT N}]
This is the common syntax used to retrieve data from a single table:
- Fields one and two are the column names of the table. To fetch all columns from the table, the * expression can be used.
- table_name indicates the table name from where data needs to be retrieved.
- The WHERE clause can be used to specify any condition in a single and multiple column.
- The Group BY function is used with aggregate functions to group the result sets.
- The HAVING clause is needed after GROUP BY to filter based on conditions for a group of rows or aggregates. If we use the HAVING clause without GROUP BY, it would act similarly...
