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 Source Patterns

Oracle

Query

CREATE TABLE sample_table
(
	sample_column varchar(10)
);

INSERT INTO sample_table(sample_column) VALUES ('text 1');
INSERT INTO sample_table(sample_column) VALUES ('text 2');

SELECT ROWID FROM sample_table;
SELECT MAX(ROWID) FROM sample_table;

Result Query 1

|ROWID             |
|------------------|
|AAASfCAABAAAIcpAAA|
|AAASfCAABAAAIcpAAB|

Result Query 2

|MAX(ROWID)        |
|------------------|
|AAASfCAABAAAIcpAAB|

Snowflake

Query

CREATE OR REPLACE TABLE PUBLIC.sample_table (
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
/*** MSC-ERROR - MSCEWI3094 - ROWID PSEUDOCOLUMN IS NOT SUPPORTED IN SNOWFLAKE, IT WAS CONVERTED TO NULL TO AVOID RUNTIME ERRORS ***/
null
FROM PUBLIC.sample_table;

SELECT MAX(/*** MSC-ERROR - MSCEWI3094 - ROWID PSEUDOCOLUMN IS NOT SUPPORTED IN SNOWFLAKE, IT WAS CONVERTED TO NULL TO AVOID RUNTIME ERRORS ***/
null) FROM PUBLIC.sample_table;

Result Query 1

|NULL|
|----|
|    |
|    |

Result Query 2

|MAX(/*** MSC-ERROR - MSCEWI3094 - ROWID PSEUDOCOLUMN IS NOT SUPPORTED IN SNOWFLAKE, IT WAS CONVERTED TO NULL TO AVOID RUNTIME ERRORS ***/
NULL)|
|------------------------------------------------------------------------------------------------------------------------------------------------|
|                                                                                                                                                |
