Bash-MySQL / try to insert string to table - mysql

Question

I try to insert string to mysql in bash, so I do the next:
message="<a href = http://www."
message="$message ${d}"
message="$message .com"
mysql -u root -pmypass -Bse 'INSERT INTO atTable VALUES (null, "'$message'")'
When I do it, I get the next massage:
mysql Ver 14.14 Distrib 5.1.69, for debian-linux-gnu (i486) using readline 6.1

Usage: mysql [OPTIONS] [database]
-?, --help Display this help and exit.
-I, --help Synonym for -?
--auto-rehash Enable automatic rehashing. One doesn't need to use
'rehash' to get table and field completion, but startup
and reconnecting may take a longer time. Disable with
--disable-auto-rehash.
-A, --no-auto-rehash
No automatic rehashing. One has to use 'rehash' to get
table and field completion. This gives a quicker start of
mysql and disables rehashing on reconnect.
-B, --batch Don't use history file. Disable interactive behavior.
(Enables --silent.)
--character-sets-dir=name
Directory for character set files.
and other commands. What I do wrong?

Answer 1

Please have a try with this one:
message="<a href = http://www."
message="$message ${d}"
message="$message .com"
mysql -u root -pmypass -Bse "INSERT INTO atTable VALUES (null, '$message')";
At least it worked for me, when I tested it with this:
message="<a href = http://www."
message="$message hello"
message="$message .com"
mysql -u root -pwhatever -Bse "SELECT '$message'";

Answer 2

Try this:
mysql -u root -pmypass -Bse "INSERT INTO atTable VALUES (null, '$message')"
The problem was the spaces in $message were ending the -e option.

Answer 3

Instead of piecing together the message variable like you did, this is easier to read:
message="<a href = http://www. $d .com"
This is equivalent to the example in the original post, though the text itself doesn't look meaningful.
You can pass your query to mysql like this:
mysql -u root -pmypass -Bse "INSERT INTO atTable VALUES (null, '$message')"
If message contains single quotes, you need to escape them, you can do like this:
message=$(echo "$message" | sed -e "s/'/\\\\'/")
Instead of putting your root password on the command line, I recommend to put that information in the .my.cnf file of your home directory, for example:
[client]
database=yourdbname
user=root
password=yourpass
However, before entering the real password, protect the file first like this:
touch .my.cnf
chmod 600 .my.cnf
