SQL/PLSQL blocks can be stripped of their comments by using regular expressions in a text editor or a scripting language. Here is an example of how to do it using Python:
import re
# SQL/PLSQL block with comments
block = '''
/*
This is a comment
*/
SELECT * FROM customers; -- This is another comment
'''
# Regular expression to match comments
comment_pattern = r'(--.*)|(/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/)'
# Remove comments using regular expression substitution
block_without_comments = re.sub(comment_pattern, '', block)
print(block_without_comments) # Output: SELECT * FROM customers;
The regular expression comment_pattern
matches both single-line comments (starting with --
) and multi-line comments (starting with /*
and ending with */
). The re.sub
function replaces all matches with an empty string, effectively removing the comments from the SQL/PLSQL block.
