Embedded SQL

Hi all,

I was trying to get my Dynamic SQL to work now after a long time and
encountering some problems.  Here is how it is.

I am just querrying a file on the basis of the input from the user. There
are 4 inputs on the screen, say Fld1, Fld2,Fld3,Fld4.  Once I exfmt and get
the user input, I am show them a browse window for matching records.  So if
user does not input any field, I will show entire file.
I have declared a string where I feed in the values. If Fld1 is input, I
will show matching records for Fld1.

                eval string = 'SELECT A, B, C, D FROM FILEA WHERE A=:FLD1'

If Fld1 & Fld2 is input, I show matching records for Fld1 & 2

                eval string = 'SELECT A, B, C, D FROM FILEA WHERE A=:FLD1 and 
B=:Fld2'

and so on...

I then do

PREPARE STATEMENT FROM STRING
DECLARE c cursor for statement
Open C
Fetch into
Close c

In the first prepare statement itself, I am getting an error saying the Fld1
not defined in the table!  If I hard code the string in the cursor like :

        Declare C cursor for select a,b,c,d, from filea where a=:fld1 and 
b=:fld2,

it works perfectly.  But this does not serve my purpose as I cannot declare
more than once in a program.

Could you please tell me where I am going wrong.

Thanks,
Sudha
