if(condition, then, else) in Oracle

Question

MySQL/MSSQL has a neat little inline if function you can use within queries to detect null values, as shown below.

SELECT

...

foo.a_field AS \"a_field\",
SELEC         


        

Answer 1

You want to use NVL, or NVL2

NVL(t.column, 0)
NVL2( string1, value_if_NOT_null, value_if_null )
