select empno from emp where firstname || lastname in ('JohnDoe', 'JoeBlow');
comes to mind... If one of firstname or lastname is null, the result of the concatenation will be null and will not
matchanything, so you might want to use a case statement to catch that case and use an empty string.
Are you stuck with that kind of construct? It seems kind of... odd.

Hi,
The following 'SELECT' query fails in psql, but it works
in Oracle sqlplus ...
mydb=# create table emp
mydb-# (firstname varchar(255),lastname varchar(255),empno int);
CREATE
mydb=# insert into emp (firstname,lastname,empno) values ('John','Doe',1234);
INSERT 44968 1
mydb=# select empno from emp where ((firstname,lastname) IN
mydb-# (('John','Doe'),('Joe','Blow')));
ERROR: parser: parse error at or near "'"
ERROR: parser: parse error at or near "'"
Whereas in sqlplus:
SQL> select empno from emp where ((firstname,lastname) IN
2 (('John','Doe'),('Joe','Blow')));
EMPNO
----------
1234
Can anyone tell me what syntax _will_ work in psql?
Many thx,
Mark
