SELECT * (asterisk)
Informix®
Informix allows you to use the star character in the select list along with other expressions:
SELECT col1, * FROM tab1 ...
IBM® DB2®
IBM DB2 does not
support the asterisk notation after another expression in the SELECT
list.
Use the table name as a prefix to the star:
SELECT col1, tab1.* FROM tab1 ...
Solution
Always use the table name with stars.
