使用正则表达式从sql中提取国家数据

Question

I got SQL for inserting countries, I just want to save some columns instead of all columns in the SQL query.

I have cleaned the data using regex but facing only one little problem. The regex doesn't match if the values are starting in the same line, I am using regex101.com for replacing

Try it here .

My Regex

(\(([0-9]),(['a-zA-Z ]*),(['a-zA-Z ]*)).*

Answer 1

The pattern I notice in your regex attempt divides in matching two groups:

• Group 1 (replaced), which contains a parenthesis, the first digits and a comma
• Group 2 (retained), which contains any character before a comma, a quote and another group of digits,
• Group 3 (replaced), which contains the rest of the string, ending in ), for every row, except the last one that ends with );

The translation of this description into regex pattern is the following:

(\(\d+,)(.*?(?=,'\d))(.*?(?:\)([,;])))

Group 1 Regex Explanation \(\d+,) :

• \( : an open parenthesis
• \d+ : any combination of digits
• , : a comma

Group 2 Regex Explanation (.*?(?=,'\d)) :

• .*? : any combination of characters (lazy - the least possible)
• (?=,'\d) : before a comma followed by a quote and a digit (excluded from the match)

Group 3 Regex Explanation (.*?(?:\)([,;]))) :

• .*? : any combination of characters (lazy - the least possible)
• (?:\)([,;])) : before a parenthesis followed by either a comma or colon

Then it's enough to replace your regex match with ($2, 1, NOW(), NOW())$4\n
