Hi, I trying to write a query that will join 2 tables. Here's the concept: Table 1: table1, primary key pk1 Table 2: table2, primary key pk2
One of the fields (f2) in table2 contains either the primary key of table1 or a NULL value. So normally a pretty basic query: SELECT table1.*, table2.pk2 FROM table1, table2 WHERE table2.f2 = table1.pk1; BUT what I would like to do is show all records of Table 1 even if there is no match in Table 2. Meaning that the reults could be table1... table2.pk2 table1... NULL Doable? Thanks. ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faqs/FAQ.html
