ROWID

Translation spec for ROWID pseudocolumn

Description

For each row in the database, the ROWID pseudocolumn returns the address of the row. (Oracle SQL Language Reference Rowid pseudocolumn)

Snowflake does not have an equivalent for ROWID. The pseudocolumn is transformed to NULL in order to avoid runtime errors.

sample_column varchar(10));

INSERT INTO PUBLIC.sample_table(sample_column) VALUES ('text 1');

INSERT INTO PUBLIC.sample_table(sample_column) VALUES ('text 2');

SELECT
