Civi is using it's own (not shared with Drupal) database. During a script to rebuild a dev/test site from production data I want to drop all the tables in the civi dev db. How do I do that?

After painstakingly trying civitables=$(drush civicrm-sql-query "show tables" | tr '\n' ',' | sed 's/,$//') && drush civicrm-sql-query "drop table $civitables" I realized I could more simply do drush civicrm-sql-query "drop table like 'civi%'" but both of these are giving me "Query failed" error. Why would these queries fail or what could I inspect to see why the failed? How can all the tables be dropped using drush?

*edits...

The drop table like... is apparently invalid sql sytax. Doh.

And the civitables=$(drush civicrm-sql-query "show tables" | tr '\n' ',' | sed 's/,$//') && drush civicrm-sql-query "drop table $civitables" appears to fail due to Cannot delete or update a parent row: a foreign key constraint fails which apparently needs SET FOREIGN_KEY_CHECKS=0; in order to work but when I do that the query passes (doesn't produce error) but fails to delete any tables.

  • Drupal has drush sql-drop and that's what I want for civicrm! – alec Mar 11 at 21:09

There's a file in the [civicrm root]/sql folder called civicrm_drop.mysql. You should be able to use that as source sql/civicrm_drop.mysql. It doesn't drop views or the canary table, but you can do that separately.

  • so like drush civicrm-sql-query --file=sites/all/modules/civicrm/sql/civicrm_drop.mysql I presume is what you mean? – alec Mar 11 at 21:14
  • I've never used drush in that way but yes if --file means use the file as a sql script then yes. Alternatively source is a sql command so drush civicrm-sql-query "source sql/civicrm_drop.mysql" should work. – Demerit Mar 11 at 21:22
  • do you mean drush civicrm-sql-query "source sites/all/modules/sql/civicrm_drop.mysql"? – alec Mar 11 at 21:24
  • Right, you'd probably have to give the path from drupal root. – Demerit Mar 11 at 21:25
  • Any idea why civi's civicrm_drop.mysql doesn't drop tables that are "views"? – alec Mar 11 at 21:46

I haven't seen anything as clean as drush sql-drop (for drupal) yet, but the following works and is more thorough than the civicrm/sql/civicrm_drop.mysql file:

#!/bin/bash
# include this in devize.sh or whatever script is being used to rebuild your dev/test site

echo "SET FOREIGN_KEY_CHECKS=0;" > drop-tables.sql
drush civicrm-sql-query "show tables" | sed -E 's/(.*)/DROP TABLE IF EXISTS `\1`;/g' >> drop-tables.sql
echo "SET FOREIGN_KEY_CHECKS=1;" >> drop-tables.sql
drush civicrm-sql-query "source drop-tables.sql"
sed -i 's/TABLE/VIEW/g' drop-tables.sql
drush civicrm-sql-query "source drop-tables.sql"
rm drop-tables.sql

# then you'd go and do something like:
# drush cvsqlc < production_db.sql
# but that's not exactly relevant to this question

  • OMG -- if running on a *BSD server the sed commands are different :/ The second sed needs '' added as an additional argument so it'd be sed -i '' 's/TABLE/VIEW/g'. – alec Mar 12 at 14:46
