Im preparing a shell script which will take mysql table dump with where clause.
Im passing table name and where condition from a parameter.
Backup command:
mysqldump -u root-p'pass' db blocked_reasons --where=" created_time < DATE(Now() - INTERVAL 2 month)" > test.sql
Run this command with parameters:
tbl="blocked_reasons"
where="--where="""created_time < DATE(Now() - INTERVAL 2 month)""""
verify with echo:
echo " mysqldump -u root -p db $tbl $where > test.sql"
mysqldump -u root-p db blocked_reasons --where="created_time < DATE(Now() - INTERVAL 2 month)" > test.sql
But when I start to execute this command Im getting errors:
mysqldump: Couldn't find table: "<"
shell mysql variable

I'd get rid of some of the spacing in your query in the --where clause. Take a look at this for an example: stackoverflow.com/questions/5658284/…

Yeah, seems its spacing issue. But its a sting right, how can I add space inside it?

I read this on a SO question.Double quotes will corrupt your string.

Nov 27 at 20:18
Ah yeah, thatll do it.. I was on the fence about suggesting to swap the double quotes to single quotes originally.

Never use -p'pass' in your backup scripts. This can be spotted by regular user in /proc/[PID]/cmdline. Instead simply assign your password to MYSQL_PWD variable within script before launching mysqldump
