TIP: Run a

DELETE

query to delete a record. You can perform all other operations by using the OPC UA methods exposed by the same objects. For more information on the SQL statements and clauses, see the SQL standard.

UPDATE

FactoryTalk Optix Studio

partially supports these statements in SQL queries:

Literal values

Supported literal values
Literal value type	Example	Notes
Integral	1520	Do not use any thousands separators. Use the Int32 type.
Real	15.025	Use . as the decimal separator. Use the Double type.
Real scientific	2.7000001072883606E-1
Boolean	true false	Use lowercase for Boolean values.
String	'string value'	Use single quotes to delimit text. Insert a single quote ( ' ) in a text string by escaping the single quote with another single quote. For example, to write 'string' , use two single quotes ''string'' in the strings.
Date and time	"2004-05-23T14:25:10.487"	Use the ISO8601 format delimited by double quotes. The date and time notation is non-standard ANSI SQL used to avoid the DATE , TIME , and TIMESTAMP keywords without ambiguity.
Regular identifier	Column1 Grüße	Do not use spaces. Start with an uppercase or a lowercase letter. You can use numeric digits, letters, and the underscore character _ .
Delimited identifier	"Water level" "SELECT"	Use double quotes ( " ) as the delimiter. In the identifier, use any character except for the " character. Any spaces at the end of the identifier are ignored.

Aliases

You can use aliases in the identifiers, derived column subqueries, and tables.

The following are examples of queries with aliases:

SELECT Timestamp AS T FROM Table1 WHERE ...

SELECT * FROM Table1 AS T WHERE ...

SELECT * FROM (SELECT * FROM Table1) AS SubQuery WHERE ...

CREATE TABLE Table1 AS SELECT Timestamp, Column1 FROM Table2

Operators

Supported operators
Operator	Example
IN	SELECT * FROM Table1 WHERE Column1 IN (10, 20, 30)
BETWEEN	SELECT * FROM Table1 WHERE Column1 BETWEEN 100 AND 200
LIKE	... WHERE column1 LIKE '%a' ... WHERE column1 LIKE '%a%' ... WHERE column1 LIKE '%bbpi!%ppo%' ESCAPE '!'
EXISTS	... WHERE EXISTS (SELECT Table1.Column1 FROM Table2)
IS	... WHERE column1 IS NULL
NOT	... WHERE column1 IS NOT NULL ... WHERE column1 NOT IS (10, 20) ... WHERE column1 NOT BETWEEN 100 AND 200 The NOT operator applies to all other operators.

Window functions

Supported window functions
Function	Example
ROW_NUMBER	ROW_NUMBER() OVER (ORDER BY Column2) ROW_NUMBER() OVER (PARTITION ON Column1 ORDER BY Column2) ROW_NUMBER() OVER (window_name PARTITION ON Column1 ORDER BY Column2)
RANK	RANK() OVER (PARTITION ON Column1 ORDER BY Column2)
DENSE_RANK	DENSE_RANK() OVER (PARTITION ON Column1 ORDER BY Column2)
AVG	AVG(Column1) OVER (PARTITION BY Column2)
SUM , MIN , MAX	SUM(Column1) OVER (PARTITION BY Column2)
