您可以使用 T-SQL REPLACE：

REPLACE(FieldWithStars,'*','STAR')

对于多个替换，您可以使用级联 REPLACE 语句。

虽然对要点没有任何线索 - 但您应该能够替换任何内容，为该特定字符寻找正确的转义序列。

You can use T-SQL REPLACE:

REPLACE(FieldWithStars,'*','STAR')

For more than one substitution you could use cascading REPLACE statements.

No clue though about bullet points - but you should be able to replace anything looking for the right escape sequence for that particular character.

这是一个较晚的答案，但当替换涉及大量令牌和/或它们的管理必须在脚本之外（即从 UI）处理时，它可能会有所帮助。此外，不建议将数据（搜索/替换标记是硬编码的）与逻辑混合。

由于聚合替换不起作用（UPDATE执行单个扫描记录），我使用了一个函数来实际执行每个字符串的聚合更新）。我预计性能会比经典解决方案低，但它具有上述优点：

-- function to perform the replacements
CREATE FUNCTION dbo.ReplaceFromTable (@s NVARCHAR(4000))
RETURNS NVARCHAR(4000)
AS
BEGIN
    DECLARE @Ret NVARCHAR(4000) = @s

    SELECT @Ret = REPLACE(@Ret, R.SearchToken, R.ReplaceToken) 
    FROM dbo.Replacements R

    RETURN @Ret
END
GO

-- drop table dbo.Replacements
create table dbo.Replacements
(
    SearchToken NVARCHAR(32) NOT NULL,
    ReplaceToken NVARCHAR(32) NOT NULL
)
GO

insert into dbo.Replacements values (N'ó', N'o'), (N'ò', N'o'), (N'*', N' ')
GO

select * from dbo.Replacements
go

-- drop table dbo.Strings
create table dbo.Strings
(
    StringId INT NOT NULL,
    String NVARCHAR(128) NOT NULL
)
GO

insert into Strings values (1, N'Some dummy string'), (2, N'Nòthing really'), (3, N'Nóthing new under the Sun'), (4, N'**Earth**')
GO

select * from dbo.Strings
GO

UPDATE S
    SET S.String = dbo.ReplaceFromTable(S.String)
FROM dbo.Strings S
GO

select * from dbo.Strings

This is a late answer, but it might be helpful when replacements involve a large number of tokens and/or their management must dealt outside of the script (i.e. from an UI). Also, mixing data (search/replacement tokens are hardcoded) with logic is not recommended.

Since aggregate replacements do not work (UPDATE does a single scan through the records), I have used a function to actually perform the aggregate updates for each string). I expect a lower performance than the classic solution, but it has the advantages mentioned above:

-- function to perform the replacements
CREATE FUNCTION dbo.ReplaceFromTable (@s NVARCHAR(4000))
RETURNS NVARCHAR(4000)
AS
BEGIN
    DECLARE @Ret NVARCHAR(4000) = @s

    SELECT @Ret = REPLACE(@Ret, R.SearchToken, R.ReplaceToken) 
    FROM dbo.Replacements R

    RETURN @Ret
END
GO

-- drop table dbo.Replacements
create table dbo.Replacements
(
    SearchToken NVARCHAR(32) NOT NULL,
    ReplaceToken NVARCHAR(32) NOT NULL
)
GO

insert into dbo.Replacements values (N'ó', N'o'), (N'ò', N'o'), (N'*', N' ')
GO

select * from dbo.Replacements
go

-- drop table dbo.Strings
create table dbo.Strings
(
    StringId INT NOT NULL,
    String NVARCHAR(128) NOT NULL
)
GO

insert into Strings values (1, N'Some dummy string'), (2, N'Nòthing really'), (3, N'Nóthing new under the Sun'), (4, N'**Earth**')
GO

select * from dbo.Strings
GO

UPDATE S
    SET S.String = dbo.ReplaceFromTable(S.String)
FROM dbo.Strings S
GO

select * from dbo.Strings
