Answer 1

这是 SQL Server 版本：

declare @param nvarchar(max) = N'INTERNAL_INSTRUCTION_NUM';

declare 
    @pos int,
    @temp nvarchar(max);

set @pos = charindex(@param, @test);

set @temp = substring(@test, @pos + len(@param), len(@test) 
                 - @pos - len(@param));

-- find first # after param
set @pos = charindex('#', @temp);
set @temp = substring(@temp, @pos+1, len(@temp) - @pos);

-- find second # after param
set @pos = charindex('#', @temp);
set @temp = substring(@temp, @pos+1, len(@temp) - @pos);

-- find the value we are looking for assuming it is enclosed between ",+" and "?%"
select substring(@temp, 3, len(@temp) - 4)

sql在字符串上查找字符
