Is there a way to execute more than one query per string in MySQL-Python?

Question

I have some input which is a string containing more than one MySQL queries, such as USE some_db; SELECT * FROM some_table;. When I store this string as s<

Answer 1

Certainly, a Python script can run multiple SQL statements from a string or list, external .sql or .txt file that can be sourced to MySQL.

However, the cur.execute command runs one SQL line one at a time. Hence, you will need to loop through each SQL line iteratively. So, consider splitting the multiple SQL commands by semicolon.

s = "USE some_db; SELECT * FROM some_table;"

# filter() removes trailing empty list item
s = filter(None, s.split(';'))

for i in s:
    # strip() removes leading and trailing white spaces  
    # semicolon is re-added per line for query run
    cur.execute(i.strip() + ';')

But be sure to remove any semicolons found in comments.
