• Field and table names are case sensitive

SELECT STATEMENT

In a select statement, you designate one more columns, separated by commas (or "*" for all columns), a table to get the data from, and additional options:

SELECT

[ DISTINCT ]

{ * | column_expr [, column_expr]* }

FROM table_reference

[WHERE where_clause]

[GROUP BY group_by_clause]

[ORDER BY order_clause]

[LIMIT limit_by_clause]

where:

DISTINCT

Eliminates duplicate rows from the result set.

Note:

For example: DISTINCT(customer_name,address)

column_expr

There are several ways to specify columns:

{ column_name | SQL Function }

[ [AS] alias]

where:

alias

Displayed as the column name in the result set, in the SQL Browser. Can also be used as a field name in a group_by_clause or order_by_clause.

For example:

SELECT CONCAT(last_name,', ',first_name) AS full_name

FROM Customer_Contacts ORDER BY full_name;
