Simple Log Service:INSERT INTO clause

Last Updated:Aug 11, 2023

You can use an INSERT INTO clause to write query and analysis results from one Logstore to another Logstore. The two Logstores belong to the same project.

Syntax

INSERT INTO target_logstore (key) 
SELECT key FROM source_logstore
Important
  • In the destination Logstore, you must create an index for the key field that you specify and enable the analysis feature for the field.

  • target_logstore must be followed by a field that you want to write to the destination Logstore. For example, * | INSERT INTO target_logstore SELECT... is an invalid statement.

  • If the data types of the specified fields do not match the data types that are supported by Simple Log Service, you must specify a data type conversion function in the SELECT statement to convert the data types of the fields. For more information, see Data type conversion functions.

  • You can use an INSERT INTO clause to write up to 10,000 data entries to a destination Logstore at a time.

  • The source and destination Logstores must reside in the Chinese mainland.
