Re: [sqlite] Difference between localtime and utc is 8 hours, but should be 4

[sqlite] Difference between localtime and utc is 8 hours, but should be 4

Hello! I'm in the Eastern US time zone, in daylight savings time. I am four hours earlier than UTC time. I have a column that stores UTC times as Julian times (floating-point numbers). The latest data point in the table was stored at about 8:41 this morning (4/21). I am getting strange

Re: [sqlite] Increasing performance of query

Thanks for your answers! First of all, my apologies with ANALYZE I meant that it increased performance (decreased query time) by orders of magnitude. Before ANALYZE the query was in the order of seconds (about 2 seconds). After ANALYZE the query was in the order of milliseconds. I tried VACUUM

[sqlite] json_tree virtual table -- on disk or in memory?

Hi sqlite-users community, I was looking at the json1 extension and came to know that json_tree is implemented as a virtual table. Does that mean that the json_tree table is stored in memory after the json is parsed by sqlite? If so, for querying json data
