In Snowflake, you can use the LAST_INSERT_ID() function to retrieve the identity of the last row that was inserted into a table with an auto-incrementing column.
Here’s an example of how to use this function:
Create a table with an auto-incrementing column:
CREATE TABLE my_table (
id INTEGER AUTOINCREMENT,
Insert a new record into the table:
INSERT INTO my_table(name) VALUES(‘John Doe’);
Retrieve the identity of the last inserted row using the LAST_INSERT_ID() function:
This will return the identity of the last row that was inserted into the my_table table.
Note that the AUTOINCREMENT keyword specifies that the id column should be automatically incremented for each new row that is inserted into the table. If you insert a record without specifying a value for the id column, Snowflake will automatically generate a unique value for the column.
Also, note that the LAST_INSERT_ID() function only works for the current session. If you perform another INSERT operation in a different session, the function will return the identity of the last row inserted in that session, not the current session.
