更改列中特定数据的任何方法，例如Mr to Dr包含名称

Question

I am trying to change the Titles of 'doctors' in a database and was just wondering was there a SQL query which I could run to change them.

The column im trying to change

What I am asking is that there is any way I can update the column to add a 'Dr' infront of the names to replace the 'Miss','Mr' etc.

I'm thinking about using a SQL Statement containing the wildcard function to update it but not sure it would change the specifics.

Thanks,

Karl

Answer 1

Use REPLACE option

UPDATE table_name
SET column_name = REPLACE(column_name, 'Mr.', 'Dr.')
WHERE column_name LIKE 'Mr.%'

Answer 2

try this

Update myTable
set name = replace(replace(name,'Miss ','Dr '),'Mr ','Dr ')

Answer 3

I might suggest doing:

update t
    set col = stuff(col, 1, charindex(' ', col + ' '), 'Dr');

This only replaces the first word in the string. You might want to be extra careful and add a where clause.

update t
    set col = stuff(col, 1, charindex(' ', col + ' '), 'Dr') 
    where col like 'Miss %' or col like 'Mr %' or
          col like 'Mrs %' or col like 'Ms %';

The problem with replace() is that it replaces all occurrences in the string. Although the honorifics are unlikely to be in a name, you could have names like "Missy Elliott".
