Thread: Insert a long text
Hello!
I want to insert a long text (up to 10.000 words) into a table (for example, table1) into a field (field1) which is a
'text'field.
I have tried the followings:
INSERT INTO table1 VALUES (' long text'...)
UPDATE table1 SET field1='long text'
and is not working.
I'm using servlets and Apache server, on Linux.
In MSAccess is working also this statement:
UPDATE table1 SET field1 = field1 & 'short text'
but in postgres I don't know how to do this.
Thank you,

What data type are you using for the text field? As far as I know, the 'text'
datatype can only take 8K.
I don't know what the maximum size for varchar is.

8K is maximum length of whole record. In your case you must use 'large
objects' as datatype for big text.

How does one do this, preferably with perl and DBI?
What is the best way to handle big (>= 8k) text fields? It would be nice if
postgres could have an easy interface for larger text sizes or a set of
example functions to deal with such chunks.
A connected question of mine is:
I have played with the data types text and varchar to store some text from a
webbrowser with a perl-DBI cgi script.
The table has one INT field called "id" and one text field where I tested
the types: text, varchar, varchar(2000) and varchar(7000).
Inserting text only works if the text is a lot smaller than 8k - only about
20 lines of text get inserted without beeing cropped.
How can I assert that the whole text gets inserted and how can I get a
message/error if the text did not fit or has been shortend? Has anybody an
example script or perl code snippet with text fields roughly 2000-4000 bytes
long?
This problem annoys me for some weeks now so I think I am an idiot and
Postgres proves it...
Any help would be great and maybe let me sleep better ;)
