SELECT
INTO
FROM
JOIN
WHERE
GROUP BY
HAVING
UNION
ORDER BY
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

<column_reference> [ ASC | DESC ] [ NULLS FIRST | NULLS LAST ]

]

[

LIMIT <expression>

[

{ OFFSET | , }

]

} | SCOPE_IDENTITY()

<expression> ::=

| COUNT( * | { [ DISTINCT ] <expression> } )

| { AVG | MAX | MIN | SUM | COUNT } ( <expression> )

[ ELSE { <expression> | NULL } ]

END

Examples

Return all columns:
SELECT * FROM Constituents
Rename a column:
SELECT [AddressLines] AS MY_AddressLines FROM Constituents
Cast a column's data as a different data type:
SELECT CAST(AnnualRevenue AS VARCHAR) AS Str_AnnualRevenue FROM Constituents
Search data:
SELECT * FROM Constituents WHERE Type = 'Home'
Return the number of items matching the query criteria:
SELECT COUNT(*) AS MyCount FROM Constituents
Return the number of unique items matching the query criteria:
SELECT COUNT(DISTINCT AddressLines) FROM Constituents
Return the unique items matching the query criteria:
SELECT DISTINCT AddressLines FROM Constituents
Summarize data:
SELECT AddressLines, MAX(AnnualRevenue) FROM Constituents GROUP BY AddressLines
See Aggregate Functions below for details.
Retrieve data from multiple tables.
SELECT c.Category, c.Fundraisers, c.Summary, o.Name, o.PhoneDoNotCall FROM Actions c INNER JOIN Constituents o ON c.ConstituentId = o.Id
See JOIN Queries below for details.
Sort a result set in ascending order:
SELECT Id, AddressLines FROM Constituents ORDER BY AddressLines ASC
Restrict a result set to the specified number of rows:
SELECT Id, AddressLines FROM Constituents 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 Constituents WHERE Type = @param

Aggregate Functions

COUNT

Returns the number of rows matching the query criteria.

SELECT COUNT(*) FROM Constituents WHERE Type = 'Home'

COUNT(DISTINCT)

Returns the number of distinct, non-null field values matching the query criteria.

SELECT COUNT(DISTINCT Id) AS DistinctValues FROM Constituents WHERE Type = 'Home'

AVG

Returns the average of the column values.

SELECT AddressLines, AVG(AnnualRevenue) FROM Constituents WHERE Type = 'Home' GROUP BY AddressLines

MIN

Returns the minimum column value.

SELECT MIN(AnnualRevenue), AddressLines FROM Constituents WHERE Type = 'Home' GROUP BY AddressLines

MAX

Returns the maximum column value.

SELECT AddressLines, MAX(AnnualRevenue) FROM Constituents WHERE Type = 'Home' GROUP BY AddressLines

SUM

Returns the total sum of the column values.

SELECT SUM(AnnualRevenue) FROM Constituents WHERE Type = 'Home'

JOIN Queries

The Provider for Blackbaud Raisers Edge NXT 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.Category, c.Fundraisers, c.Summary, o.Name, o.PhoneDoNotCall FROM Actions c INNER JOIN Constituents o ON c.ConstituentId = o.Id

Left Join

A left join selects all rows in the FROM table and only matching rows in the JOIN table:

SELECT c.GiftStatus, o.CheckNumber, o.CheckoutTransactionId, o.PaymentMethod FROM Gifts c LEFT JOIN GiftPayments o ON c.Id = o.GiftsId

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)
