Gets or sets the query or stored procedure that is used to select incremental changes from the local database. Note It is recommended that the query that is specified include the clause ORDER BY [sync_row_timestamp]. Ordering rows by timestamp value ensures that if a synchronization session ...
If you aim to build a database-agnostic application, you should account for differences in database column types. For example, the date/time column type in PostgreSQL is calledtimestamp, while the same column in MySQL is calleddatetime. You can handle this in adb_type()method by checking ...
To sort or group a table if the sorting or grouping is done on a leftmost prefix of a usable index (for example,ORDER BYkey_part1,key_part2). If all key parts are followed byDESC, the key is read in reverse order. SeeSection 8.2.1.14, “ORDER BY Optimization”, andSection 8.2.1.1...
In this method, you can convert your Oracle data to a CSV file using SQL plus and then transform it according to the compatibility. You then can stage the files in S3 and ultimately load them into Snowflake using the COPY command. This method can be time taking and can lead to data in...
