PRIMARY KEY ( `assert_id` )
) ENGINE = INNODB DEFAULT CHARSET = utf8 COMMENT = 'Admin Assert Table' AUTO_INCREMENT =1;
MySQL said: Documentation
#1046 - No database selected

Answer 1

When you create a table you need to select a database for that table to insert into
USE databaseName;
run this before your script
USE casasdl;
CREATE TABLE IF NOT EXISTS `admin_assert` (
`assert_id` INT( 10 ) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT 'Assert ID',
`assert_type` VARCHAR( 20 ) DEFAULT NULL COMMENT 'Assert Type',
`assert_data` TEXT COMMENT 'Assert Data',
PRIMARY KEY ( `assert_id` )
) ENGINE = INNODB DEFAULT CHARSET = utf8 COMMENT = 'Admin Assert Table' AUTO_INCREMENT =1;

Answer 2

Like you can read in error, you have to select your database.
Add USE yourDatabase; at the beginning of the code.

Answer 3

mysql or each db backend should import your tables into a Database , so it needs you introduce a db name , indeed you should tell to mysql :
use mydbname;
you can create it from :
mysqladmin -uroot -p create mydbname
mysql -uroot -p mydbname < mysqlfile.sql

Answer 4

if you are using external php, then do not use use database syntax or mysql-select_db("database"); syntax. Instead use mysqli_connect which accept database name.

Answer 5

The USE db_name statement tells MySQL to use the db_name database as the default (current) database for subsequent statements. The database remains the default until the end of the session or another USE statement is issued.
Refer: http://dev.mysql.com/doc/refman/5.6/en/use.html

Answer 6

Another option is within phpmyadmin Select DB from the left sidebar and inside it import will work.
