问题 I have a column named params in a table named reports which contains JSON. I need to find which rows contain the text 'authVar' anywhere in the JSON array. I don't know the path or level in which the text could appear. I want to just search through the JSON with a standard like operator. Something like: SELECT * FROM reports WHERE params LIKE '%authVar%' I have searched and googled and read the Postgres docs. I don't understand the JSON data type very well, and figure I am missing something

问题 I am creating a table that has a features jsonb column. There will be a dynamic set of features (each row can have an unknown set of features). Each feature is boolean true/false values. Example: Row 1: feature: { "happy": true, "tall": false, "motivated": true } Row 2: feature: { "happy": true, "fast": true, "strong": false } Row 3: feature: { "smart": true, "fast": true, "sleepy": false } What would be the best way to index this column such that I can make queries to find all rows with

问题 Apologies in advance... long-winded question. Suppose I have a table table_x with 20 fields in it: table_x_id (identity pk) int1 int... int8 text1 text... text8 jsonb1 jsonb2 Now suppose I want to maintain rapid access to grouped data (say, fields int1, int2, text1_id, text2_id and jsonb1) in table_x . Call that Report 1 . Data doesn't really play an important role in posing this question, but here's an imaginary snippet from Report 1 : +-------------------------------------------------------

问题 My database contains a table which has a column with jsonb type , and I want to update a part of these data using functions/operators from postgreSQL . Given we have this: { "A":[ {"index":"1"}, {"index":"2"} ], "B":[ {"index":"3"}, {"index":"4"} ] } Let's say we went to add a key with an empty array to objects from "A" array, in order to have: { "A":[ {"index":"1", "myArray":[]}, {"index":"2", "myArray":[]} ], "B":[ {"index":"3"}, {"index":"4"} ] } How can I proceed? I've already tried this

问题 I want to get all records where any value in jsonb field contains a text regardless of key. For example: field contains json {k1: 'hello', k2: 'world'} . I want to get this record by the text 'hello'. I don't care about keys or any json structure, only values. One dirty hack is to cast the field to varchar where jsonb_field::varchar like ... , but this is ugly and it will match keys and {} as well. Another dirty hack looks like this: SELECT * FROM mytable AS m1 WHERE ( SELECT string_agg(value
