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 Spreadsheet1_Sheet1
- Rename a column:
SELECT [Column1] AS MY_Column1 FROM Spreadsheet1_Sheet1
- Cast a column's data as a different data type:
SELECT CAST(AnnualRevenue AS VARCHAR) AS Str_AnnualRevenue FROM Spreadsheet1_Sheet1
- Search data:
SELECT * FROM Spreadsheet1_Sheet1 WHERE Column2 = 'Bob'
- Return the number of items matching the query criteria:
SELECT COUNT(*) AS MyCount FROM Spreadsheet1_Sheet1
- Return the number of unique items matching the query criteria:
SELECT COUNT(DISTINCT Column1) FROM Spreadsheet1_Sheet1
- Return the unique items matching the query criteria:
SELECT DISTINCT Column1 FROM Spreadsheet1_Sheet1
- Summarize data:
SELECT Column1, MAX(AnnualRevenue) FROM Spreadsheet1_Sheet1 GROUP BY Column1
See Aggregate Functions for details. - Retrieve data from multiple tables.
SELECT c.Name, o.ItemCount, o.TotalCost, o.Date FROM Spreadsheet1_Customers c INNER JOIN Spreadsheet1_Orders o ON c.Id = o.CustomerId
See JOIN Queries for details. - Sort a result set in ascending order:
SELECT Id, Column1 FROM Spreadsheet1_Sheet1 ORDER BY Column1 ASC
- Restrict a result set to the specified number of rows:
SELECT Id, Column1 FROM Spreadsheet1_Sheet1 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 Spreadsheet1_Sheet1 WHERE Column2 = @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 Google Sheets.
SELECT * FROM Spreadsheet1_Sheet1 WHERE Query = 'Column3 > 100'
