pass parameter from bash to mysql script

pass parameter from bash to mysql script

I'm trying to pass parameter from bash script to mysql script. The bash
script is
#!/bin/bash
for file in `ls *.symbol`
do
path=/home/qz/$file
script='/home/qz/sqls/load_eval.sql'
mysql -u qz -h compute-0-10 -pabc -e "set @pred = '$path'; source $script;"
done
The load_eval.sql is
use biogrid;
load data local infile @pred into table lasp
fields terminated by ','
lines terminated by '\n'
(score, symbols);
When running the bash script, I got error the message:
You have an error in your SQL syntax; check the manual that corresponds to
your MySQL server version for the right syntax to use near '@pred
into table lasp ..
It seems the value of the parameter @pred is not passed into mysql script.
