I have ONE column in MySQl table which contains this format:
https://open.spotify.com/track/AAABBBCCC
and I'd like to leave just AAABBBCCC, and not the entire column! The last parte is always the same.
Is that possible? Thanks and sorry for my english!
You can use SQL REPLACE function to do that.
UPDATE your_table_name
SET your_column_name = REPLACE(your_column_name, 'https://open.spotify.com/track/', '')
For more information you can read SQL statement to remove part of a string
Use REPLACE to delete the wanted text from your column:
UPDATE Table1 SET Column1 = REPLACE(Column1,'https://open.spotify.com/track/','')

I am trying to find the correct SQL query to UPDATE fields from a table that contain at least some text. My idea is something like this.
UPDATE this IN tablename WHERE fieldname = "%value%"
I know something is wrong but I am new to this and in need of some help. Thanks
INSERT statement will add new row(s) into your table.
The UPDATE statement will edit your current row(s).
You should at least shout if you want some help.
Please post something more for your question, like table name, column names and your exact requirement.
UPDATE statement is something like this:
UPDATE tablename SET field1 = 'TEST' WHERE fieldname LIKE "%value%";
I need to search and UPDATE my database for column values starting with a blankspace..
SQL
UPDATE table
SET column substring(column, 1)
WHERE column has blankspace
How can i do this?
EDIT
Oh yeah.
Reason is to erase blankspace...
Use LTRIM() function to remove starting blank spaces.
Try this:
UPDATE table SET column = LTRIM(column)
I think you should be explicit and use like:
UPDATE table
SET column = substring(column, 1)
WHERE column like ' %';
I'm basically looking to remove all of the text from a record called FaxOutNumber except for where it contains no... it isn't consistent in the records, so sometimes its just NO! and other times its no#emailaddress.com.
I'd like:
FaxOutNumber:
5145555#emailaddress.com
no!#emailadrress.com
to change to:
FaxOutNumber:
[null]
no
I'd actually like to just turn this field into a simple BIT where the "No" becomes a "1" or true value as well.
Thanks in advance!
You can use a regular expression:
ALTER TABLE my_table ADD COLUMN isNoRecord BOOLEAN;
UPDATE my_table SET isNoRecord = FaxOutNumber RLIKE '^no(!?)(#.+)?$';
ALTER TABLE my_table DROP COLUMN FaxOutNumber;
You can try this--
UPDATE tableName SET FaxOutNumber = IF(FaxOutNumber RLIKE '^par',"",FaxOutNumber);
I have a database table in MYSQL with around 1000 rows. In the table I have a column called 'overview'. In each row, this column has some value and at the end of that value I have a specific line (text) starting with: 'Source...'
Now what I want is, I want to remove this line from each column and replace it with some other text content.
I believe it can be accomplished with some smart query.
You can simply use REPLACE in your query like this
UPDATE your_table SET col_name = REPLACE(col_name , ‘Source...’, ‘new_val’)
WHERE col_name LIKE '%Source...';
Check Out the SQLFIDDLE.
MySQL database has a handy and simple string function REPLACE() that allows table data with the matching string (from_string) to be replaced by new string (to_string).
The syntax of REPLACE is:
REPLACE (text_string, from_string, to_string)
In your case, you can do this way:
UPDATE `tableName` SET `column` = REPLACE(column , 'Source...', 'Replaced Value')
Use Replace
update TBL
set overview = Replace(picture, 'Source..', 'replacement')
keep a backup of the table before anything.Or you can do it on a copy.
you can do this by following:
update table_name set col_name = replace(column_name , ‘Source...’, ‘Replaced String...’);
