I have a table which carries around 172 entries, with different column names, however I want to update all of them with a simple query.
I have a name entered in the name column (http://prntscr.com/j9qeg6)
I would like to replace the III with I've using a simple query,
Now I've been checking and trying however it does not seem to work.
I used the following query which got me closest to the result however its not working.
UPDATE item_template SET name = CONCAT("IV", SUBSTRING(name, LENGTH("III ")+1));
Does anyone have an idea on this?
Apostrophe ' instead of Double quotes "
You can try use REPLACE function.
UPDATE item_template
SET name = REPLACE(name, ' III', ' IV');

I have a lot of entries in a table, at a specific column that contains values such as:
VVÎVV
VEVÎÎ
ÎÎEVÎ
ÎÎEVÎ
..and so on.
What I'd like to do is run a query that would update that specific column, on every row, stripping out the &, the circ and the ; it finds - while preserving whatever else is in there.
Or just replacing Î with I while also preserving the other things in there? Whichever is easier. If replacing, then Î would get replaced with `I`
Can/how do you do that in MySQL?
I'm currently reading about LIKE and Wildcard but I'm not seeing how to put a query like that together so far.
Using MySQL, InnoDB table name is ghix and column name is zuff
If I understand your question properly then you want to replace Î with I, right?
If so then you can run below query to replace all in that column. Here my table name is temp. You can use yours.
UPDATE temp SET column_name = REPLACE(column_name, 'Î', '|');
Thank you.
You can do that with REGEXP expression.
UPDATE table name SET columname = columname REGEXP 'regexp'
should do the trick
I want to update all fields of a column, a lot of them have a desired string in there, but I want this string to be in only each field once, for instance :
"MyString OtherString MyString AnotherString AndAnother MyString"
to
"MyString OtherString AnotherString AndAnother"
would you have any idea on how to achieve this ?
If "MyString" will always occur as the first term in the field, this would work:
update MyTable set MyField = replace(MyField, ' MyString','')
The key point above is that we look for occurrences of "MyString" with a leading space, so the first occurrence at the beginning of the field will be ignored.
However, my guess is this might be too fragile - what if the first occurrence of "MyString" is not at the beginning of the field?
in this latter case you need the following:
UPDATE
MyTable
SET
MyField =
CONCAT(
LEFT(MyField,INSTR(MyField,'MyString') + LENGTH('MyString')),
REPLACE(RIGHT(MyField, LENGTH(MyField) - (INSTR(MyField,'MyString') + LENGTH('MyString'))), 'MyString','')
)
What this does is to split the field into two, the first part up to and including the first occurrence of "MyString", and the second part replacing all further occurrences of it.
I have 2000 products with row that is using serialized data and I need to update specific string
this is the row name data
a:35:{s:11:"expire_days";s:3:"30d";s:12:"trial1_price";s:0:"";s:11:"trial1_days";s:0:"";s:12:"is_recurring";s:0:"";s:10:"start_date";s:0:"";s:5:"terms";s:24:"$150 for 1 Per license";s:12:"rebill_times";s:0:"";s:15:"paypal_currency";s:0:"";s:4:"##11";N;s:3:"url";s:0:"";s:8:"add_urls";s:0:"";s:4:"##12";N;s:5:"scope";s:0:"";s:5:"order";s:4:"1010";s:11:"price_group";s:1:"7";s:13:"renewal_group";s:2:"28";s:14:"need_agreement";s:0:"";s:13:"require_other";a:1:{i:0;s:0:"";}s:16:"prevent_if_other";N;s:4:"##13";N;s:19:"autoresponder_renew";s:0:"";s:16:"dont_mail_expire";s:0:"";s:13:"joomla_access";s:2:"36";s:10:"files_path";s:108:"products/Boxes8.zip|Box 8

and only thing I need changed is
s:24:"$150 for 1 Per license";
any help is appreciated.
You should probably SELECT the row, make your changes, then UPDATE with the new value. The answer to this question may be helpful if you need to do this database side.
How to do a regular expression replace in MySQL?
If you want to replace the value of that single field with something else, you can use the following query:
UPDATE table SET col = CONCAT(
LEFT(col, LOCATE('s:24:"', col) + 5), -- up to and including the opening quote
'Now for free', -- new replacement text
SUBSTR(col, LOCATE('"', col, LOCATE('s:24:"', col)+6)) -- closing quote and everything after that
) WHERE col LIKE '%s:24:"$150 for 1 Per license"%'
Note that there is potential for trouble: if the value of one of your fields should end in 's:24:', then that combined with the closing quote would get misinterpreded as the location you're looking at. I consider this risk unlikely, but if you want to play it safe, you might want to check for that with an elaborate regular expression that can deal with quoted strings and escaped quotes.
I have a string such as,
"This is a sting and I dont know how long I am"
I want to turn every word in string into a row for my sql table so that I get:
ThisIs a string and I dont know etc...
I need to be able to do this with the MySql command line. (I also need an adjacent column to all be filled with ones on every row, incase that helps/changes your answer) I was thinking I could somehow use INSERT String (Words, num) Values (#words, 1) but I dont know how to get it to add every word. Is there any easy way to do this? If not, how would it be done?
MySQL does not have a function to split a delimited string. This problem is heavily discussed on MySQL manual page (search "split"), although there is no direct solution to handle variable number of elements.
Instead of that, I would help myself to generate such a query:
SELECT CONCAT('INSERT INTO t1 VALUES ("', REPLACE(REPLACE(TRIM(string_column), '"', '\\"'), ' ', '", "'), '")') FROM t2_with_string
Using MS Access 2010.
I have a field in a table that contains windows path names surrounded by quotes, like this
"C:\My Documents\Photos\img1.jpg"
"C:\My Documents\Photos\products\gizmo.jpg"
"C:\My Documents\Photos\img5.jpg"
and so on.
I need to get rid of the quotes so the column looks like this:
C:\My Documents\Photos\img1.jpg
C:\My Documents\Photos\products\gizmo.jpg
C:\My Documents\Photos\img5.jpg
Is there a way to write an update query to do this?
OR a better way to do it altogether?
If you will be doing this from within an Access session, using Access 2000 or later, you can use the Replace() function in an update query to remove the quotes. Remove would mean replace them with an empty string.
UPDATE YourTable
SET path_field = Replace(path_field, '"', '');
If any of those path strings could include quotes within them (yuck!), consider the Mid() function ... ask it to start at the 2nd character (skipping the lead quote), and return the number of characters equivalent to Len(path_field) - 2
UPDATE YourTable
SET path_field = Mid(path_field, 2, Len(path_field) - 2);
Either way, you may want to include a WHERE clause to ignore rows without path_field values.
WHERE Len(path_field) > 0
And if you must do this again when new data is added, use a different WHERE clause to ensure you UPDATE only those rows whose path_field values start and end with quotes.
WHERE path_field Like '"*"'
That was using the * wild card for Access' default ANSI 89 mode. If you will do this from ADO (ANSI 92 mode), use the % wild card.
WHERE path_field Like '"%"'
... or use ALike and the % wild card with either mode.
WHERE path_field ALike '"%"'
The solution with REPLACE already mentioned by others works, but removes ALL quotes, even if they are in the middle of the string.
If you only want to remove quotes at the beginning or at the end, but leave quotes in the middle of the string as they are, you can do it with the following two queries:
Remove first character if it's a quote:
update YourTable
set YourField = right(YourField, len(YourField) - 1)
where left(YourField, 1) = '"'
Remove last character if it's a quote:
update YourTable
set YourTable = left(YourField, len(YourField) - 1)
where right(YourField, 1) = '"'
To make this a permanent change, you might run an update query that looked something like this:
UPDATE [Your Table]
SET [Your Table].[Your Field] = Replace([Your Table].[Your Field],"""","")
This will get rid of all quotes, even if they aren't at the beginning or end. Post back if that's not exactly what you want.
Assuming your column name is MyColumn and table name is MyTable, you can use this sql to update your data to get rid of quotes.
UPDATE MyTable
SET MyColumn = REPLACE(MyColumn,'"','')
