Question

Im storing a person object as JSON in my SQLite database. The table will have few 1000 records of person objects. What i need is to query person based on the “name” attribute.

After investigation i figured out using GLOB method of SQLite to perform a RegEx kind of search in the JSON elements.

My Sample JSON is something like this.

{"name":"john","age":"22","father-name":"jackson"}

Now i want a RegEx matcher to get me all the records that matches a part of the SubString provided with the name attribute in JSON. And it should be case insensitive too.

For Ex: “ohn” search should fetch me john’s record.

Answer 1

If you do want to go down the regex route the following will extract the record:

/\{"name":"\w*ohn\w*[^\}]+\}/i

This will match each of these:

{"name":"john","age":"22","father-name":"jackson"}
{"name":"john","age":"22","father-name":"johnson"}
{"name":"johnny","age":"22","father-name":"smith"}

but not:

{"name":"fred","age":"22","father-name":"hall"},
{"name":"mike","age":"22","father-name":"johnson"}
{"name":"bob","age":"22","father-name":"todd"}
