string functions and operators

[Neil Stlyz <neilstylz@xxxxxxxxx>]

Hello,

 

I have a dilema and I was hoping someone here may offer guidance or assistance. I bet this is a very simple question for someone out there but I am having problems coming up with a solution. Here it is...

 

suppose I have a field with the following values:

 

77.1

77.2

134.1

134.2

134.3

5.1

5.2

 

I need two seperate SELECT queries. One would return the following values (everything left of the decimal point)

 

77

77

134

134

5

5

 

The second query would return all of the values to the right of the decimal point:

 

1

2

1
2

3

1

2

 

 

Now, I have been using the following information (although very Greek) to try to solve this problem:

 

http://www.postgresql.org/docs/current/static/functions-string.html

 

And I have been playing around with the syntax of the following:

 

            substring('112.5' from '%#"___.#"_' for '#')

 

but the aforementioned is not quite working out... can someone please show me a string function that will produce the desired results?

 

Thanks!
