i have created a 'do while' statement that returns all table names in my database and using 'select * from {my table names}' then, using 'for each' statement i have been able to return the name of all fields in my database. i cannot, for the life of me, figure out how to assign a variable the name of the field with a returned value of the same field....ie if my field was documentid, i want to set
'dim documentid = rs("documentid"'. unfortunately, i am doing this in a loop and must assign the value in the loop while not knowing the name 'documentid'. i have tried to 'redim myarray(i)' but that's what it does is "redim" so that won't help, plus, i can't rs.recordcount to get out of the loop because i am using rs("field_name" and get a returned recordcount value of -1.
any help would be much appreciated.
thanks

to late to think about this but the last bit...., can you not change the cursor type
of the recordset to return the record count?

the cursor type should not influence the recordcount property. r u certain that u r not getting an empty rs?
as to assigning variables names from a dynamic value - it ain't posible, since memory allocation occurs during compelation(or in asp @ intepretation), and not @ runtime.
therefore u cannot go
dim i
for i = 0 to 100
dim variablei '' this doesnot make sense!!!
next
"i have tried to 'redim myarray(i)' but that's what it does is "redim" so that won't help" -- not quite clear but I presume you are losing values
then try:
Redim Preserve Variablename(length-1)
'' the preserve key word keeps the already assigned values in the array.
an array is the right road to walk, for this secanario
