MySql僅替換列中的單個單詞

Question

我試圖單獨使用mySql，試圖用microsoft-corp替換microsoft一詞。

我嘗試使用此sql， update names set names = replace(names,'microsoft','microsoft-corp') ，但是它將替換每個microsoft 。 有沒有一種方法可以使它僅替換Microsoft這個詞？

原始數據

"id"    "names"
"1"     "/microsoft"
"2"     "/microsoft/microsoft-word"
"3"     "/microsoft/microsoft-word/microsoft-word-tutorials"
"4"     "/microsoft/microsoft-word/microsoft-word-tutorials/examples"

"id"    "names"
"1"     "microsoft >"
"2"     "microsoft > microsoft-word"
"3"     "microsoft > microsoft-word > microsoft-word-tutorials"
"4"     "microsoft > microsoft-word > microsoft-word-tutorials > examples"

預期正確的結果

"id"    "names"
"1"     "/microsoft-corp"
"2"     "/microsoft-corp/microsoft-word"
"3"     "/microsoft-corp/microsoft-word/microsoft-word-tutorials"
"4"     "/microsoft-corp/microsoft-word/microsoft-word-tutorials/examples"

使用我上面的查詢當前不正確的結果

"id"    "names"
"1"     "/microsoft-corp"
"2"     "/microsoft-corp/microsoft-corp-word"
"3"     "/microsoft-corp/microsoft-corp-word/microsoft-corp-word-tutorials"
"4"     "/microsoft-corp/microsoft-corp-word/microsoft-corp-word-tutorials/examples"

Answer 1

怎么樣：

update names set names = replace(names,'/microsoft/','/microsoft-corp/')

update names set names = '/microsoft-corp' where names = '/microsoft'

update names set names = replace(names,'microsoft >','microsoft-corp >')

Answer 2

我可能會分兩次通過，盡管您可能一次就能做到。

update names set names = replace(names,'/microsoft/','/microsoft-corp/');
update names set names = '/microsoft-corp' where names = '/microsoft';
