SELECT Syntax
The following syntax diagram outlines the syntax supported by the SQL engine of the driver:
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 Deals
- Rename a column:
SELECT [UserEmail] AS MY_UserEmail FROM Deals
- Cast a column's data as a different data type:
SELECT CAST(AnnualRevenue AS VARCHAR) AS Str_AnnualRevenue FROM Deals
- Search data:
SELECT * FROM Deals WHERE UserName = 'Bob'
- Return the number of items matching the query criteria:
SELECT COUNT(*) AS MyCount FROM Deals
- Return the number of unique items matching the query criteria:
SELECT COUNT(DISTINCT UserEmail) FROM Deals
- Return the unique items matching the query criteria:
SELECT DISTINCT UserEmail FROM Deals
- Summarize data:
SELECT UserEmail, MAX(AnnualRevenue) FROM Deals GROUP BY UserEmail
See Aggregate Functions for details. - Retrieve data from multiple tables.
SELECT d.UserName, u.Email, u.Phone, u.LastLogin FROM Deals d INNER JOIN Users u ON d.UserId = u.Id
See JOIN Queries for details. - Sort a result set in ascending order:
SELECT Id, UserEmail FROM Deals ORDER BY UserEmail ASC
- Restrict a result set to the specified number of rows:
SELECT Id, UserEmail FROM Deals 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 Deals WHERE UserName = @param
Pseudo Columns
Some input-only fields are available in SELECT statements. These fields, called pseudo columns, do not
appear as regular columns in the results, yet may be specified as part of the WHERE clause. You can use pseudo columns to access additional features from Pipedrive.
SELECT * FROM Deals WHERE Query = 'Value > 100'
