MrPowers opened a new issue, #1781: URL: https://github.com/apache/sedona/issues/1781
Parameterized queries [were recently added to Spark](https://www.databricks.com/blog/parameterized-queries-pyspark) and allow for some really clean syntax when shifting from the Python API to the SQL API. We should consider adding this interface to Sedona. ## Status quo Create a geometry object for Minnesota: ```python minnesota = 'POLYGON((-96.4517 43.5008,-91.2195 43.5017,-91.3101 43.8226,…))’ ``` Create a DataFrame: ```python df = sedona.read.format("shapefile").option("charset", "UTF-8").load(user_uri + extract_dir) ``` Create a temporary view: ```python df.createOrReplaceTempView('gauges') ``` Run a query with a f-string: ```python query = sedona.sql(f''' select geometry, Status, Waterbody, Observed from gauges where st_intersects(geometry, ST_GeomFromWKT('{minnesota}')) ''') ``` ## How to make this more concise with a parameterized query This could be nicer with a parameterized query: ```python sedona.sql(""" select geometry, Status, Waterbody, Observed from {df} where st_intersects(geometry, ST_GeomFromWKT('{minnesota}')) """, df=df, minnesota=minnesota) ``` The parameterized query saves you from creating the temporary view and using f-strings. It would be great if the parameters were also sanitized to prevent SQL injection vulnerabilities. ## Another parameterized query example This can be even cooler. Assume Minnesota is a geometry object as follows: ```python minnesota_wkt = 'POLYGON((-96.4517 43.5008,-91.2195 43.5017,-91.3101 43.8226,…))’ minnesota = ST_GeomFromWKT(minnesota_wkt) ``` Then, we can pass the geometry object directly in the parameterized query: ```python sedona.sql(""" select geometry, Status, Waterbody, Observed from {df} where st_intersects(geometry, minnesota) """, df=df, minnesota=minnesota) ``` -- This is an automated message from the Apache Git Service.
