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> ]
} [ , ... ]
[ [

] JOIN <table_reference> [ ON <search_condition> ] [ [ AS ] <identifier> ]
] [ ... ]
[ WHERE <search_condition> ]
[ GROUP BY <column_reference> [ , ... ]
[ HAVING <search_condition> ]
[ UNION [ ALL ] <select_statement> ]

Examples
Return all columns:
SELECT * FROM EventsRename a column:
SELECT [location_displayName] AS MY_location_displayName FROM EventsCast a column's data as a different data type:
SELECT CAST(Reminder AS VARCHAR) AS Str_Reminder FROM EventsSearch data:
SELECT * FROM Events WHERE Id = 'Jq74mCczmFXk1tC10GB'Return the number of items matching the query criteria:
SELECT COUNT(*) AS MyCount FROM EventsReturn the number of unique items matching the query criteria:
SELECT COUNT(DISTINCT location_displayName) FROM EventsReturn the unique items matching the query criteria:
SELECT DISTINCT location_displayName FROM EventsSummarize data:
SELECT location_displayName, MAX(Reminder) FROM Events GROUP BY location_displayNameSee Aggregate Functions below for details.
Retrieve data from multiple tables.
SELECT Customer.CustomerName, MainContact.DisplayName FROM Customer, Customer_Maincontact WHERE Customer.CustomerID=Customer_Maincontact.ParentCustomerIDSee JOIN Queries below for details.
Sort a result set in ascending order:
SELECT Id, location_displayName FROM Events ORDER BY location_displayName ASCRestrict a result set to the specified number of rows:
SELECT Id, location_displayName FROM Events 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 Events WHERE Id = @param
Aggregate Functions
COUNT
Returns the number of rows matching the query criteria.
SELECT COUNT(*) FROM Events WHERE Id = 'Jq74mCczmFXk1tC10GB'
COUNT(DISTINCT)
Returns the number of distinct, non-null field values matching the query criteria.
SELECT COUNT(DISTINCT Id) AS DistinctValues FROM Events WHERE Id = 'Jq74mCczmFXk1tC10GB'
AVG
Returns the average of the column values.
SELECT location_displayName, AVG(Reminder) FROM Events WHERE Id = 'Jq74mCczmFXk1tC10GB' GROUP BY location_displayName
MIN
Returns the minimum column value.
SELECT MIN(Reminder), location_displayName FROM Events WHERE Id = 'Jq74mCczmFXk1tC10GB' GROUP BY location_displayName
MAX
Returns the maximum column value.
SELECT location_displayName, MAX(Reminder) FROM Events WHERE Id = 'Jq74mCczmFXk1tC10GB' GROUP BY location_displayName
SUM
Returns the total sum of the column values.
SELECT SUM(Reminder) FROM Events WHERE Id = 'Jq74mCczmFXk1tC10GB'
JOIN Queries
The Provider for Acumatica 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 Customer.CustomerName, MainContact.DisplayName FROM Customer, Customer_Maincontact WHERE Customer.CustomerID=Customer_Maincontact.ParentCustomerID
Left Join
A left join selects all rows in the FROM table and only matching rows in the JOIN table:
SELECT Groups.displayName, Conversations.Topic FROM Groups LEFT OUTER JOIN Conversations ON Groups.Id=Conversations.GroupId
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)
