SELECT Syntax
The following syntax diagram outlines the syntax supported by the SQL engine of the provider:
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> ] } [ , ... ] [ [ INNER | { { LEFT | RIGHT | FULL } [ OUTER ] } ] 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> { = | > | < | >= | <= | <> | != | LIKE | NOT LIKE | IN | NOT IN | IS NULL | IS NOT NULL | AND | OR | CONTAINS | BETWEEN } [ <expression> ] } [ { AND | OR } ... ] |
Examples
Return all columns:
SELECT * FROM Teams
Rename a column:
SELECT [location_displayName] AS MY_location_displayName FROM Teams
Cast a column's data as a different data type:
SELECT CAST(Reminder AS VARCHAR) AS Str_Reminder FROM Teams
Search data:
SELECT * FROM Teams WHERE Id = 'Jq74mCczmFXk1tC10GB'
Return the number of items matching the query criteria:
SELECT COUNT(*) AS MyCount FROM Teams
Return the number of unique items matching the query criteria:
SELECT COUNT(DISTINCT location_displayName) FROM Teams
Return the unique items matching the query criteria:
SELECT DISTINCT location_displayName FROM Teams
Summarize data:
SELECT location_displayName, MAX(Reminder) FROM Teams GROUP BY location_displayName
See Aggregate Functions below for details.
Retrieve data from multiple tables.
SELECT Teams.displayName, Channels.desciption FROM Teams, Channels WHERE Teams.Id=Channels.TeamId
See JOIN Queries below for details.
Sort a result set in ascending order:
SELECT subject, location_displayName FROM Teams ORDER BY location_displayName ASC
Restrict a result set to the specified number of rows:
SELECT subject, location_displayName FROM Teams LIMIT 10
Parameterize a query to pass in inputs at execution time. This enables you to create prepared statements and mitigate SQL injection attacks.
SELECT * FROM Teams WHERE Id = @param
Aggregate Functions
COUNT
Returns the number of rows matching the query criteria.
|
COUNT(DISTINCT)

|
AVG
Returns the average of the column values.
|
MIN
Returns the minimum column value.
|
MAX
Returns the maximum column value.
|
SUM
Returns the total sum of the column values.
|
JOIN Queries
The Provider for Microsoft Teams supports standard SQL joins like the following examples.
Inner Join
An inner join selects only rows from both tables that match the join condition:
|
Left Join
A left join selects all rows in the FROM table and only matching rows in the JOIN table:

|
L_LAST_WEEK()
Every day in the preceding week.
|
