kandi X-RAY | pg_query Summary

pg_query is a Ruby library typically used in Utilities, Parser, PostgresSQL applications. pg_query has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

This Ruby extension uses the actual PostgreSQL server source to parse SQL queries and return the internal PostgreSQL parsetree. In addition the extension allows you to normalize queries (replacing constant values with ?) and parse these normalized queries into a parsetree again. When you build this extension, it builds parts of the PostgreSQL server source (see libpg_query), and then statically links it into this extension. This is slightly crazy, but is the only reliable way of parsing all valid PostgreSQL queries. You can find further examples and a longer rationale here:

You can delete multiple whitespaces within a text not with trim() but quite well with preg_replace(). Make a combination of trim() and preg_replace().

Just set up your web server so that HTML files parse through PHP. This varies depending on your server. Alternatively, just save the file as .php and it should run!

These are the summary of issue:

There is an issue of not going inside the if clause and data not inserted.
Need to compute the target_progress_date as the difference between the end_date and start_date and all the interval months to be computed and stored in the variable so as to insert into the project_target_progress table.

Viz: Start date :1-1-2021, End date : 1-12-2021 Months: 1-1-2021 1-2-2021 1-3-2021 .... 12-12-2021

Looking at the query you replied with to my question in comments, it seems that you're passing an invalid query to Postgres.

If you were correctly checking for and handling errors, you would find that FROM_UNIXTIME() does not exist in PG's dialect of SQL, so you will need to find an alternative and adapt your query so that it is compatible.

This question will likely have a replacement that you can use, particularly this answer which recommends using to_timestamp - though you'll need to make sure your column type is compatible (I can only guess as to what you're using), though I am sure this is the culprit).

There is no need to create a json string manually. Just build up and array and encode it to json with json_encode()
You have to set JSON content-type in the response headers
Closing ?> tag is redundant and is not recommended to use (see PSR-12)

So eventually your code should look like this

How to format PostgreSQL query to return geojson cleanly?

Asked 2021-Aug-06 at 09:03

I'm having a similar issue to this post where using pg_fetch_all is returning the data I want buried in an associative array. When I run the query in PgAdmin I get the results I expect as a feature collection, so what's the correct way to format my query and PHP to return the result as a geojson object? My aim is to get geojson for a Leaflet map. I'm querying a shapefile of single locations that I want some attributes associated.

Here's my query and code snippet:

Answered 2021-Aug-06 at 09:03

So, in this case it's just a matter of correctly accessing the values in the array with $geodata[0]['row_to_json']
