Compare two MySQL dump files
Unfortunately, you cannot force the ordering of columns in a mysqldump. You can, however, use the table INFORMATION_SCHEMA.COLUMNS. You will need the following:


MySQL Instance with the old data loaded
MySQL Instance with the new data loaded
Some Patience and Scripting


With this setup in mind, here is what you need to do:

STEP 01) Use Query to Present Columns Ordered Per Database/Table

Here is the Query:

SELECT CONCAT(table_schema,'.',table_name),
GROUP_CONCAT(column_name ORDER BY column_name)
FROM information_schema.columns WHERE table_schema NOT IN
('information_schema','performance_schema')
GROUP BY table_schema,table_name;


This will give you every table followed by a CSV list of alphabetically-sorted columns

STEP 02) Launch this Column Query From Both MySQL Instances

IPADDR_OLD=10.1.20.30
IPADDR_NEW=10.1.20.40
SQLSTMT="SELECT CONCAT(table_schema,'.',table_name),"
SQLSTMT="${SQLSTMT} GROUP_CONCAT(column_name ORDER BY column_name)"
SQLSTMT="${SQLSTMT} FROM information_schema.columns WHERE table_schema NOT IN"
SQLSTMT="${SQLSTMT} ('information_schema','performance_schema')"
SQLSTMT="${SQLSTMT} GROUP BY table_schema,table_name"
mysql -u... -p... -h${IPADDR_OLD} -ANe"${SQLSTMT}"  &gt; column_listing1.txt
mysql -u... -p... -h${IPADDR_NEW} -ANe"${SQLSTMT}" &gt;&gt; column_listing2.txt
cat column_listing1.txt  &gt; column_listing.txt
cat column_listing2.txt &gt;&gt; column_listing.txt


Run the Column Query and Collect the Results in column_listing.txt

STEP 03) Perform Unique Sort ; Check For Duplicate Table Names

sort -u &lt; column_listing.txt &gt; column_listing.unq
UNQ_LINES=`wc -l &lt; column_listing.unq`
TXT_LINES=`wc -l &lt; column_listing.txt`
(( DIF_LINES = (UNQ_LINES + UNQ_LINES - TXT_LINES) / 2))
echo ${DIF_LINES}


If everything is identical, DIF_LINES should 0. Otherwise, there are duplicates present.

STEP 04) If There Are Duplicates, Find Them

diff column_listing1.txt column_listing2.txt


Give it a Try !!!
