Hello,
yesterday i opend a topic related to LDAP App installation. Today i treid to install external storage support app and i got an identical (more or less) message.
"An exception occurred while executing 'CREATE TABLE oc_external_mounts (mount_id BIGINT AUTO_INCREMENT NOT NULL, mount_point VARCHAR(128) NOT NULL, storage_backend VARCHAR(64) NOT NULL, auth_backend VARCHAR(64) NOT NULL, priority INT DEFAULT 100 NOT NULL, type INT NOT NULL, PRIMARY KEY(mount_id)) DEFAULT CHARACTER SET utf8 COLLATE utf8_bin ENGINE = InnoDB': SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'oc_external_mounts' already exists"
I guess this is a database access problem, but i am far from being an expert. Can someone translate this message into human language for me ?
It reads like the db-table already exits. How can i check/delete this in MariaDB-Client ? Unfortunately i am not familiar to SQL
