Replace all single quotes in a string query

Question

I have a file with SQL queries similar to this:

INSERT INTO Bank (bankCode, swiftCode, bankName, country, countryCode, locationCode, 
address, city) 
VALUES ('MIDL', 'MIDLGB2102N', 'Hsbc Bank Plc', 'United Kingdom', 'GB',
'21', '', 'Bishop's Stortford');

I have to replace all single quotes inside a string literal in order to be able to execute the query.

Can someone provide a regular expression in order to achieve that?

For example the above query should be:

INSERT INTO Bank (bankCode, swiftCode, bankName, country, countryCode,
locationCode, 
address, city) 
VALUES ('MIDL', 'MIDLGB2102N', 'Hsbc Bank Plc', 'United Kingdom', 'GB',
'21', '', 'Bishop''s Stortford');

Replace 'Bishop's Stortford' with 'Bishop''s Stortford' . Replace ' with ''

Answer 1

You have PDO::quote function in PHP for this purpose. Check this link: http://php.net/manual/en/pdo.quote.php

If you want a pattrn for regex replace: /(\\(|\\s)'([\\w ']*)'(,|\\))/ Or in PHP: preg_replace("/(\\(|\\s)'([\\w ']*)'(,|\\))/", '$1"$2"$3', $line);

Answer 2

The easiest approach would likely be something akin to:

/[^,(]\\s*'\\s*[^,)]/

This would match all ' characters which are not preceded by or following a comma or a paren (only other valid MySQL characters). I included a search for spaces because those are also possible valid characters.

That would certainly match everything. I'm not terribly familiar with how MySQL Workbench parses replaces in regular expressions, so I cannot be much assistance there.

To import via MySQL Workbench do the following:

1. Go to excel and have your data the way you need to reflect your table structure
2. In excel Save As -> CSV
3. In workbench right click on table and choose 'Select Rows'
4. In result set, click icon 'Import Records from External File'
5. Select your CSV
6. Import
