I have a Firebird 3.x database with a table MyTable and this field:
Code: Select all
MyField BLOB SUB_TYPE 1 SEGMENT SIZE 512
Code: Select all
select cast(MyField as varchar(8000))
from MyTable
where ID = 123
Code: Select all
unable to allocate memory from operating system
If I use this SQL statement in an 3rd party database management tool (IBExpert) an run it, everything is ok.
Older versions of IBDAC have executed this code without any problems.
What can we do?
