Maybe you can try to execute the script in sql server, then type
to view tables and relevant information.
Remember that a sql file is not really a database, it is a script. You can run the script from any tool, but I’d use command line. This is navicat connected to mysql?
mysql -u username -p databasename < script.sql
password: **
And then the results can be seen using navicat or any other tool
If the .sql file has statements such as «CREATE TABLE. » and then later on «INSERT INTO. » then the script is possibly creating the tables and inserting the data.
To allow that to happen, the tables need to not exist in the database. You can then run the script and it will create the tables and fill in the data.
If the tables do exist, you can always either delete them, or change the CREATE to an ALTER and the script should then run.
Hope that helps.

Как открыть таблицу в базе данных?
Вошел под пользователем в базу данных, нужно посмотреть содержимое таблицы «Couriers» , просматриваю содержимое БД командой \dt
Далее делал SQL запрос простой — SELECT * FROM Couriers; и выдает ошибку — ERROR: relation «couriers» does not exist

Очевидно psql на скрине, соответственно postgresql.
Приглашение командной строки -# говорит о том, что это уже не начало запроса, а вы что-то напечатали уже ранее. И psql считает, что вы пишете запрос далее, затем отправляет его весь целиком. Команды самого psql при этом обрабатываются так же.
О том же самом говорит LINE 2.
По таблицам — обратите внимание на регистр. from couriers и from Сouriers — это обращение к таблице couriers. А регистрозависимое имя синтаксически отличается по стандарту.
Просмотр и редактирование таблиц SQL Server в графическом режиме
Иногда бывает необходимо произвести некоторые элементарные действия с базой данных, например найти некое значение и\или изменить его. Для тех, кто постоянно работает с базами и владеет языком запросов, эта задача не составит труда, но если вы видите SQL Server в первый раз, то проще всего просмотреть и отредактировать данные в графическом режиме.
Для этого надо открыть SQL Server Management Studio, найти в разделе «Databases» нужную базу и раскрыть ее. Затем в разделе «Tables» выбрать таблицу и правой клавишей мыши вызвать контекстное меню. В этом меню есть два пункта — «Select Top 1000 Rows» и «Edit Top 200 Rows».
Select Top 1000 Rows, как следует из названия, выводит первые 1000 строк таблицы
а Edit Top 200 Rows открывает для редактирования первые 200 строк таблицы. Это очень удобно, так как таблицу можно быстро пролистать, найти требуемую информацию и изменить ее.
При необходимости дефолтные значения 200\1000 можно изменить. Для этого надо открыть меню «Tools», перейти к пункту «Options»
открыть вкладку «SQL Server Object Explorer» и в разделе «Table and View Options» установить необходимые значения. А если поставить 0, то будет выводиться все содержимое базы без ограничений.
Все вышеописаное применимо ко всем более-менее актуальным версиям, начиная с SQL Server 2008 и заканчивая SQL Server 2016.
