To extract text from a JSONB array in PostgreSQL, you can use the json_array_elements_text
function. This function takes a JSONB array as input and returns each element of the array as text.
Here is an example:
1
|
SELECT json_array_elements_text('["apple", "banana", "orange"]'::jsonb); |
This will return:
1 2 3 4 5 |
json_array_elements_text ------------------------- apple banana orange |
You can also use the jsonb_array_elements_text
function if you are working directly with a JSONB column in a table:
1
|
SELECT jsonb_array_elements_text(jsonb_column_name) FROM table_name; |
This will return each element of the JSONB array stored in the jsonb_column_name
column of the table_name
table as text.
