To demonstrate, the following will produce the result 6: String concatenation in My SQL requires the CONCAT() function so there is no ambiguity here and My SQL converts the strings to floats and adds them together.I actually think the reason the initial query wasn't working is most likely because the $points variable was not in fact set to the user's current points.

The row/s affected value is reported as 1 if a row is inserted, and 2 if a row is updated, unless the API's Where two rows match the unique keys match, only the first is updated.

This can be unsafe and is not recommended unless you are certain what you are doing.

This will use the SQL UPDATE command with the WHERE clause to update the selected data in the My SQL table tutorials_tbl.

The following example will update the tutorial_title field for a record having the tutorial_id as 3.

Note that the warning shown below appears in Maria DB 5.5 and before, but has been removed in Maria DB 10.0, as Maria DB now assumes that the keys are checked in order, as shown in SHOW CREATE TABLE.
