从json字符串oracle中提取

Question

I have JSON string in a column like below. oracle version - 12c

{
[
{
"Employee_id": 1
,"Salary":3206.93
}
]
}

How do I remove first flower brace and the square bracket..

Result should look like below..

    {
    "Employee_id": 1
    ,"Salary":3206.93
    }

Tried using regex like SELECT regexp_substr('"abc{[{def}]}ghi"', '\\[(.+)\\]') match FROM dual;

But it didn't work..

Answer 1

select replace(replace(myColumn, '{[{', '{'), '}]}', '}')
from myTable

Note, this method will ONLY work if this column is always going to contain a single element of a JSON array, and if the JSON object doesn't contain any other JSON objects... otherwise it could break. Use at your own risk :)
