db1 = Database('db1')
db2 = Database('db2')

Optional arguments in database defining:

Option key	Postgresql default	Mysql default
host	'postgresql'	'mysql'

⚠️ WARNING: Dont change these properties in QUERA judge tests. These must be same default values

3. Use utils:

• Create database:

db1.create()

• Drop database:

db1.drop()

• Init data (run sql command without fetching results) with sql string or sql file path:

db1.init(sql_string)
# or
db1.initf(sql_file_path)

• Run query with fetching results

col_names, records = db1.run_query(sql_string)

• Compare two result of run_query:

status, message = Database.compare_query_result(col_names_1, records_1, col_names_2, records_2)

• Compare two database instances:

status, message = db1.is_equal(db2)

• Compare two database instances on a table:

status, message = db1.is_equal_on_table(db2, table_name)

SQL parser to find submission queries

from sql_judge_utils.parser import get_queries, get_query
submission_file_path = 'path/to/submission.sql'
queries = get_queries(submission_file_path)
# or
submission_file_path = 'path/to/submission.sql'
query_number = 2
query = get_query(submission_file_path, query_number)
