RE: SQL QUERY

["Srinivas Boggula" <Srinivas.Boggula@xxxxxxxxx>]

Hi Pete Helgren,

If we give host variables in select statement it says Error

Below is the Error message.

MSG ID  SEV  RECORD  TEXT

SQL0206  30      24  Position 38 Column BDD not in specified tables.  
SQL0206  30      24  Position 53 Column EDD not in specified tables.  
                                               Message Summary   

How do I solve this query?

Thanks in Advance

Srinivas,

I usually start with an interactive SQL session to test my assumptions.

I can't quite tell from your post but if the year month and day are all 
two digit numeric fields, then you'll need to parse out similar fields 
from your prompt and then do the compare.  I'll assume you know how to 
pass the parameters to the RPG and then parse out the relevant year 
month and date.

host variables are pbmm,pbdd,pbyy (for the parameters for the beginning 
date) and pemm,pedd,peyy (for the parameters for the ending date).  I'll

also assume that your date fields in the file are fmm,fdd,fyy

That said, the SQL should look something like:

select name from myfile where fyy>=byy and fyy <= eyy and fdd >= bdd and

fdd >= edd and fmm >= bmm and fmm <= emm. 

You could use the "between" keyword as well.  You could concatenate the 
fields in the file and compare them. There are many ways to do this and 
there are probably more and less efficient ways to do it.  However, I 
recommend that you use interactive SQL to test your assumptions and then

copy/paste that into your code and add your parameters as host
variables.
