SQL Syntax

Here is the syntax for the SQL SELECT statement that the SQL parser recognizes.

Considerations

• SQL syntax is case insensitive.
• Field and table names are case sensitive

Legend

• [ x ] - Optional (one or none)
• [, x ... ] - Optional additional values, in a comma-separated list
• x | y - Choose one. Curly braces are added when needed: { x | y } ...
• CAPITALIZED - SQL Keyword (case insensitive)
• italicized - Value you supply. (Table names and column names are case-sensitive)

SELECT Statement

In a select statement, you designate one more columns separated by commas (or "*" for all columns), plus a table or join 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_by_clause]

[LIMIT limit_clause]

where:

DISTINCT

Eliminates duplicate rows from the result set.

For example: DISTINCT(customer_name,address)

column_expr

* | table_alias.* | column_name [ [AS] alias ] | expr [AS] alias

where:

alias

Displayed as the column name in the result set, in the SQL Browser.
Can 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;
