LIMIT
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

Examples
Return all columns:
SELECT * FROM Spreadsheet1_Sheet1Rename a column:
SELECT [Column1] AS MY_Column1 FROM Spreadsheet1_Sheet1Cast a column's data as a different data type:
SELECT CAST(AnnualRevenue AS VARCHAR) AS Str_AnnualRevenue FROM Spreadsheet1_Sheet1Search data:
SELECT * FROM Spreadsheet1_Sheet1 WHERE Column2 = 'Bob'Return the number of items matching the query criteria:
SELECT COUNT(*) AS MyCount FROM Spreadsheet1_Sheet1Return the number of unique items matching the query criteria:
SELECT COUNT(DISTINCT Column1) FROM Spreadsheet1_Sheet1Return the unique items matching the query criteria:
SELECT DISTINCT Column1 FROM Spreadsheet1_Sheet1Summarize data:
SELECT Column1, MAX(AnnualRevenue) FROM Spreadsheet1_Sheet1 GROUP BY Column1See Aggregate Functions below 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.CustomerIdSee JOIN Queries below for details.
Sort a result set in ascending order:
SELECT Id, Column1 FROM Spreadsheet1_Sheet1 ORDER BY Column1 ASCRestrict a result set to the specified number of rows:
SELECT Id, Column1 FROM Spreadsheet1_Sheet1 LIMIT 10Parameterize 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
Aggregate Functions
COUNT
Returns the number of rows matching the query criteria.
SELECT COUNT(*) FROM Spreadsheet1_Sheet1 WHERE Column2 = 'Bob'
COUNT(DISTINCT)
Returns the number of distinct, non-null field values matching the query criteria.
SELECT COUNT(DISTINCT Id) AS DistinctValues FROM Spreadsheet1_Sheet1 WHERE Column2 = 'Bob'
AVG
Returns the average of the column values.
SELECT Column1, AVG(AnnualRevenue) FROM Spreadsheet1_Sheet1 WHERE Column2 = 'Bob' GROUP BY Column1
MIN
Returns the minimum column value.
SELECT MIN(AnnualRevenue), Column1 FROM Spreadsheet1_Sheet1 WHERE Column2 = 'Bob' GROUP BY Column1
MAX
Returns the maximum column value.
SELECT Column1, MAX(AnnualRevenue) FROM Spreadsheet1_Sheet1 WHERE Column2 = 'Bob' GROUP BY Column1
SUM
Returns the total sum of the column values.
SELECT SUM(AnnualRevenue) FROM Spreadsheet1_Sheet1 WHERE Column2 = 'Bob'
JOIN Queries
The Provider for Google Sheets supports standard SQL joins like the following examples.
Inner Join
An inner join selects only rows from both tables that match the join condition:
SELECT c.Name, o.ItemCount, o.TotalCost, o.Date FROM Spreadsheet1_Customers c INNER JOIN Spreadsheet1_Orders o ON c.Id = o.CustomerId
Left Join
A left join selects all rows in the FROM table and only matching rows in the JOIN table:
SELECT c.Name, o.ItemCount, o.TotalCost, o.Date FROM Spreadsheet1_Customers c LEFT JOIN Spreadsheet1_Orders o ON c.Id = o.CustomerId
Date Literal Functions
The following date literal functions can be used to filter date fields using relative intervals. Note that while the <, >, and = operators are supported for these functions, <= and >= are not.
L_TODAY()
The current day.
SELECT * FROM MyTable WHERE MyDateField = L_TODAY()
L_YESTERDAY()
The previous day.
SELECT * FROM MyTable WHERE MyDateField = L_YESTERDAY()
L_TOMORROW()
The following day.
SELECT * FROM MyTable WHERE MyDateField = L_TOMORROW()
L_LAST_WEEK()
Every day in the preceding week.
SELECT * FROM MyTable WHERE MyDateField = L_LAST_WEEK()
L_THIS_WEEK()
Every day in the current week.
SELECT * FROM MyTable WHERE MyDateField = L_THIS_WEEK()
L_NEXT_WEEK()
Every day in the following week.
SELECT * FROM MyTable WHERE MyDateField = L_NEXT_WEEK()
Also available:
L_LAST/L_THIS/L_NEXT MONTH
L_LAST/L_THIS/L_NEXT QUARTER
L_LAST/L_THIS/L_NEXT YEAR
L_LAST_N_DAYS(n)
The previous n days, excluding the current day.
SELECT * FROM MyTable WHERE MyDateField = L_LAST_N_DAYS(3)
L_NEXT_N_DAYS(n)
The following n days, including the current day.
SELECT * FROM MyTable WHERE MyDateField = L_NEXT_N_DAYS(3)
Also available:
L_LAST/L_NEXT_90_DAYS
L_LAST_N_WEEKS(n)
Every day in every week, starting n weeks before current week, and ending in the previous week.
SELECT * FROM MyTable WHERE MyDateField = L_LAST_N_WEEKS(3)
L_NEXT_N_WEEKS(n)
Every day in every week, starting the following week, and ending n weeks in the future.
SELECT * FROM MyTable WHERE MyDateField = L_NEXT_N_WEEKS(3)
Also available:
L_LAST/L_NEXT_N_MONTHS(n)
L_LAST/L_NEXT_N_QUARTERS(n)
L_LAST/L_NEXT_N_YEARS(n)
