<p><font face="Arial" size="2">Hello,</font><p><font face="Arial" size="2">I'm not sure if this is even possible, but I'llthrow it by you anyway. </font><p><font face="Arial" size="2">Say I have 2 tables:</font><p><font face="Arial" size="2">Table1: With columns number and name </font><p><font face="Arial" size="2">1.1 test1</font><br /><font face="Arial"size="2">1.2 test2</font><br /><font face="Arial" size="2">1.3 test3</font><br /><font face="Arial" size="2">1.4 test4</font><p><font face="Arial" size="2">Table2: With column number and results</font><p><font face="Arial"size="2">1.1 pass</font><br /><font face="Arial" size="2">1.2 fail</font><br /><font face="Arial" size="2">1.3 pass</font><br /><font face="Arial" size="2">1.4 fail</font><p><font face="Arial" size="2">What I wouldlike to do is add a new column to Table2 called name and populate the name from table 1 and add it to table 2. So,table 2 will look like:</font><p><font face="Arial" size="2">1.1 pass test1</font><br /><font face="Arial" size="2">1.2 fail test2</font><br /><font face="Arial" size="2">1.3 pass test3</font><br /><font face="Arial"size="2">1.4 fail test4</font><p><font face="Arial" size="2">**NOTE: in same cases if you do a "selectname from table1 where number='1.1'" you might get multiple matches, I guess we would need to use "distinct" ?</font><p><fontface="Arial" size="2">I've never interacted two tables before, so I'm not even sure where to start with this.</font><p><font face="Arial" size="2">I'm using postgres 7.4. </font><p><font face="Arial" size="2">Thanks all. </font>
