Need to return a p value for a specified z score in PL/SQL

I need to return a p value for a specified z score in PL/SQL

is there a statistical function I can use to do this...for example

z score   (IN)         p value (OUT)
0.00                           .5
-0.67                          .25
-1.28                          .1
-1.65                          .05
-2.33                           .01

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I don't think there is any statistical function for this.

We can write a simple select statement similar to

SELECT p_value
INTO out_variable
WHERE z_score = in_variable;

I need to derive the p value, there isn't a table to lookup the value
Can you provide more information like where these values are?

I have done more research now and confirmed tjere isn't a premade solution.  I have created a table with the necessary values and that will work for me just fine
Thanks for trying to help!
