IoT Platform：QueryDeviceBySQL

Description

• You can query devices on Enterprise Edition instances only in the China (Shanghai) and Japan (Tokyo) regions.
• The QueryDeviceBySQL operation can return up to 10,000 devices each time you call the operation. For more information, see the "Syntax of LIMIT clauses" section of this topic.

QPS limits

You can call this API operation up to 10 times per second per account.

Request parameters

If you want to call the QueryDeviceBySQL operation to query devices, you must specify an SQL-like statement. The SQL-like statement must contain a SELECT clause and a WHERE clause. The statement can also contain an ORDER BY clause and a LIMIT clause. Each statement cannot exceed 400 characters in length.

Examples:

Syntax of LIMIT clauses

Description:

• = and !=: If you use these operators, the values of the fields that you want to query can be null.

• LIKE: If you use this operator, only prefix match is supported. The prefix must be at least four characters in length and cannot contain special characters, such as backslashes (\), forward slashes (/), ampersands (&), plus signs (+), hyphens (-), exclamation points (!), parentheses (), colons (:), tildes (~), braces {}, asterisks (*), and question marks (?). The prefix must end with a percent sign (%).

  Example: SELECT * FROM device where product_key = "a1*********" and name LIKE "test%" limit 10.

In addition to the preceding operation-specific request parameters, you must configure common request parameters when you call this operation. For more information about common request parameters, see Common parameters.
