SELECT Syntax
The following syntax diagram outlines the syntax supported by the Microsoft Planner adapter:
SELECT {
[ TOP <numeric_literal> | DISTINCT ]
{
*
| {
<expression> [ [ AS ] <column_reference> ]
| { <table_name> | <correlation_name> } .*
} [ , ... ]
}
[ INTO csv:// [ filename= ] <file_path> [ ;delimiter=tab ] ]
{
FROM <table_reference> [ [ AS ] <identifier> ]
} [ , ... ]
[
JOIN <table_reference> [ ON <search_condition> ] [ [ AS ] <identifier> ]
] [ ... ]
[ WHERE <search_condition> ]
[ GROUP BY <column_reference> [ , ... ]
[ HAVING <search_condition> ]
[ UNION [ ALL ] <select_statement> ]
[
ORDER BY
<column_reference> [ ASC | DESC ] [ NULLS FIRST | NULLS LAST ]
]
[
LIMIT <expression>
[
{ OFFSET | , }
<expression>
]
]
} | SCOPE_IDENTITY()
<expression> ::=
| <column_reference>
| @ <parameter>
| ?
| COUNT( * | { [ DISTINCT ] <expression> } )
| { AVG | MAX | MIN | SUM | COUNT } ( <expression> )
| NULLIF ( <expression> , <expression> )
| COALESCE ( <expression> , ... )
| CASE <expression>
WHEN { <expression> | <search_condition> } THEN { <expression> | NULL } [ ... ]
[ ELSE { <expression> | NULL } ]
END
| <literal>
| <sql_function>
<search_condition> ::=
{
<expression> { = } [ <expression> ]
} [ { AND | OR } ... ]
Examples
- Return all columns:
SELECT * FROM Tasks
- Rename a column:
SELECT "startDateTime" AS MY_startDateTime FROM Tasks
- Cast a column's data as a different data type:
SELECT CAST(AnnualRevenue AS VARCHAR) AS Str_AnnualRevenue FROM Tasks
- Search data:
SELECT * FROM Tasks WHERE TaskId = 'BCrvyMoiLEafem-3RxIESmUAHbLK'
- The Microsoft Planner APIs support the following operators in the WHERE clause: =.
SELECT * FROM Tasks WHERE TaskId = 'BCrvyMoiLEafem-3RxIESmUAHbLK';
- Return the number of items matching the query criteria:
SELECT COUNT(*) AS MyCount FROM Tasks
- Return the number of unique items matching the query criteria:
SELECT COUNT(DISTINCT startDateTime) FROM Tasks
- Return the unique items matching the query criteria:
SELECT DISTINCT startDateTime FROM Tasks
- Sort a result set in ascending order:
SELECT TaskId, startDateTime FROM Tasks ORDER BY startDateTime ASC
