Import .sql File into Multiple MySQL Databases

juergen d's answer is of course correct; however, considering your error message, you can also add to your SQL file at the beginning line like:

USE your_database_name;

This should also do the job and let you import under the Workbench.

When you are using mysqldump, the exported file will be saved in the current folder. It doesn't matter under what path it is. Just when importing from command line you need to be at the same folder or specify path to the file. But this isn't the case when you are using visual tool like Workbench, where you need to select the file from folder tree anyway.

There is no way to do this with MySQL own tools. If you look closer it makes sense that you have to create your table first, you have to specify datatypes for the fields of your csv file, possible indexes and so on. MySQL can´t predict which datatype you want to use, so here is some manual work to do.

On the other hand you can use external scripts to archive what you want, a quick and dirty example would be:

#!/bin/bash
# create table for import
head -1 test.csv | awk '{split($0,f,","); printf "create table test (%s INT, %s VARCHAR(50));",f[1],f[2]}' | mysql -u USER -pPASS SCHEMA
# import csv
mysql -uUSER -pPASS SCHEMA -e "LOAD DATA LOCAL INFILE 'test.csv' INTO TABLE testcsv FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\n' IGNORE 1 LINES"

Above "script" lefts plenty of room for optimization, it should only give you a basic idea how to archive what you need with common Linux tools.
