Question

我想取一个字段，搜索2个可能名称中的1个：cross或memory。根据它是哪一个，将其替换为相应的img。

我当前的代码（有效）如下：

SELECT REPLACE(column_name,'cross','<img src=\"crossimg.png\" />') AS 'column_name'
FROM my_table;

我希望它是这样的：

SELECT REPLACE(column_name, if == 'cross' then img1, elseif == 'memory' then img2) AS 'column_name'
FROM my_table;

Answer 1

您可能正在寻找案例陈述：

SELECT case when column_name = 'cross' then img1 
when column_name='memory' then img2
else column_name end as column_name from my_table;

Answer 2

我想通了，我最终选择了：

$sql = "SELECT REPLACE(REPLACE(column_name,'second','<img src=\"secondimg.png\" />'),'first','<img src=\"firstimg.png\" />') AS column_name from my_table;

多个替换语句SQL？
