    <p>I am migrating a MySQL 5.1 database in Amazon's EC2, and I am having issues tables with longblob datatype we use for image storage. Basically, after the migration, the data in the longblob column is a different size, due to the fact that the character encoding seems to be different.</p> <p>First of all, here is an example of before and after the migration:</p> <p>Old:</p> <pre><code>x??]]??}?_ѕ??d??i|w?%?????q$??+? </code></pre> <p>New:</p> <pre><code>x��]]����_ѕ��d��i|w�%�����q$��+� </code></pre> <p>I checked the character set variables on both machines and they are identical. I also checked the 'show create table' and they are identical as well. The client's are both connecting the same way (no SET NAMES, or specifying character sets).</p> <p>Here is the mysqldump command I used (I tried it without --hex-blob as well):</p> <pre><code>mysqldump --hex-blob --default-character-set=utf8 --tab=. DB_NAME </code></pre> <p>Here is how I loaded the data:</p> <pre><code>mysql DB_NAME --default-character-set=utf8 -e "LOAD DATA INFILE 'EXAMPLE.txt' INTO TABLE EXAMPLE;" </code></pre> <p>Here are the MySQL character set variables (identical):</p> <p>Old:</p> <pre><code>+--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | latin1 | | character_set_connection | latin1 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | latin1 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ </code></pre> <p>New:</p> <pre><code>+--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | latin1 | | character_set_connection | latin1 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | latin1 | | character_set_server | latin1 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ </code></pre> <p>I'm not sure what else to try to be able to run mysqldump and have the blob data be identical on both machines. Any tips would be greatly appreciated.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
