I've created a MySQL database to store a large amount of text. Since
the text data type in MySQL is limited to 255 characters, I added a
BLOB column. I created an PHP input screen to enter the large text.
It seems to work. But, I cannot verify the entry, because the
standard select SQL does not display the contents. I want to
retrieve the contents from the database and display on a web page.
The retrieval seems to occur. But, I can't display the results,
because I must not be done the proper conversion from BLOB to ordinary
text.
Can somebody help me resolve this problem?
Here is the insert code I'm using.
$newtext = addslashes($blo b);
@ $db = mysql_connect(' localhost', '<database>', '<password>');
if (!$db)
{
echo "Error: Could not connect to database. Please try again
later.";
exit;
}
mysql_select_db ("<database> ");
$query = "insert into blog values ('$newtext')";
$result = mysql_query($qu ery);
if ($result)
{
echo mysql_affected_ rows()." text item inserted into
database.";
}
Here is the retrieval code I'm using.
$query = "select blogtext from blog";
$result = mysql_query($qu ery);
while ($row = mysql_fetch_arr ay($result)) {
$blog = $row['blogtext'];
$wraptext = wordwrap($blog, 80, "\n", 1);
echo $wraptext;
}
It displays nothing on my page.
Thanks in advance. 5 2680
I noticed that Message-ID:
<e4************ **************@ posting.google. com> from Bob Kaku
contained the following: $query = "insert into blog values ('$newtext')";
$query = "insert into blog (blogtext) values ('$newtext')";

Geoff,
I tried your suggestion. The insert seems to work. But, I still have
the problem of not being able to display the contents of this BLOB
column. Thanks anyway. Perhaps, someone else has a solution.

'Seems' to? Can't you check using phpMyAdmin or something?

Actually, TEXT can store 64k. BLOB isn't for text, it's for binary data
(although the only real difference AFAIK is that using the binary types turns
off case-insensitivity).
VARCHAR can only store 255.

Yes, thanks for the answer. I actually found this out myself by doing
a little more research. I now know I can use TEXT, MEDIUMTEXT or
LONGTEXT. But, TEXT seems fine for most uses. I need to examine the
online manual a little deeper before posting a message

Hello,
I've a problem retrieving a blob column from oracle.
I'm using oledbadapter to fill a dataset like that

I'm also using ColumnMapping to have more friendly column headers in

The Fill method send an error with no explaznation except this "the type is
not managed".
Has somebody ideas about to solve that ?

Dear Group,
I'm connecting in C# with remote (BSD) MySQL server with ODBC Driver,
and I'm trying to find the best sollution in such problem:
As I've read on MySQL manual, they have suggested table design
including the BLOB-Fieldtype size in UInt64, where they've stored,
while inserting, the size of inserted BLOB data. But in the matter of
fact, I'm interested if it's necessary to include in table this integer
field? Is there any way...
