SELECT Syntax
The following syntax diagram outlines the syntax supported by the Active Directory adapter:
SELECT {
[ TOP <numeric_literal> ]
{
*
| {
<expression> [ [ AS ] <column_reference> ]
| { <table_name> | <correlation_name> } .*
} [ , ... ]
}
[ INTO csv:// [ filename= ] <file_path> [ ;delimiter=tab ] ]
{
FROM <table_reference> [ [ AS ] <identifier> ]
}
[ WHERE <search_condition> ]
[
ORDER BY
{ <column_reference> [ ASC | DESC ] } [ , ... ]
]
[
LIMIT <expression>
]
} | SCOPE_IDENTITY()
<expression> ::=
| <column_reference>
| @ <parameter>
| ?
| COUNT( * | { <expression> } )
| { AVG | MAX | MIN | SUM | COUNT } ( <expression> )
| <literal>
| <sql_function>
<search_condition> ::=
{
<expression> { = | >= | <= | != | LIKE | AND | OR } [ <expression> ]
} [ { AND | OR } ... ]
Examples
Return all columns:
SELECT * FROM User
Rename a column:
SELECT "CN" AS MY_CN FROM User
Search data:
SELECT * FROM User WHERE CN = 'Administrator';
The Active Directory APIs support the following operators in the WHERE clause: =, >=, <=, !=, LIKE, AND, OR.
SELECT * FROM User WHERE CN = 'Administrator';
Sort a result set in ascending order:
SELECT Id, CN FROM User ORDER BY CN ASC
