我试图在我的问题上找到可能的解决方案,但没有成功。假设我有一个包含许多记录的TEST表,其中一列称为CA_GROUP。该列包含以下值:
{"TEST1":"1","TEST2":"2"}
我想将此部分',“TEST3”:“3”添加到该列中已存在的值。所以结果应该是:
{"TEST1":"1","TEST2":"2","TEST3":"3"}
我唯一知道的是:
update test t
set t.ca_group = replace(t.ca:group, '{"TEST1":"1","TEST2":"2"}'
, '{"TEST1":"1","TEST2":"2","TEST3":"3"}')
where id = xxxxxx
and other conditions.
update test t
set t.ca_group = replace (t.ca:group, '{"CODE1":"1","CODE2":"2"}'
, '{"CODE1":"1","CODE2":"2","TEST3":"3"}')
where id = xxxxxx
and other conditions.
但这对我来说效率不高,因为我有很多记录,我需要逐个在所有列中添加相同的值。有没有最聪明的方法呢?
答案 0 :(得分:0)
如何追加' TEST3'每个现有价值?
