buffer overflow

buffer overflow

buffer overflow


For some reason I am continually getting the following message:

buffer overflow. Use SET command to reduce ARRAYSIZE or increase MAXDATA.

I get this when I do  a select * from a particular table. That table contains
a long value.

Yet I have tried setting the maxdata and arraysize to no avail
can anyone help?



RE: buffer overflow

I would speculate that your adjustments to arraysize and maxdata didn't go far enough to solve the problem.  There is a formula for calculating maxdata.  For each column retrieved by the query calculate the following:

Memory usage = 7n + n*d + d + 2h + t + 111 in bytes
n = ARRAYSIZE (number of rows)
d = column width in the output of SQL*Plus (the display length)
h = column heading length
t = table name length

Add up the calculated memory usage for each column and set maxdata to the sum.  It's wise to add a little extra for imperfections in the formula.

I hope this helps.
