Question

In Sybase and MSSqlServer TransactSQL, we have a function IsNull(columnName,valueForNull) to return a typed default value when a column value is null. How can I replicate this functionality in SQLite?

Example in TransactSQL:

select IsNull(MyColumn,-1) as MyColumn from MyTable

If MyColumn is null, this expression will return -1 as the value of MyColumn. Want to do something similar in SQLite.

(Yes, I know I can write my own wrapper function to handle this – that’s not the answer I’m looking for)

TIA

You can use ifnull:

select ifnull(MyColumn,-1) as MyColumn from MyTable
