edit

There are several methods for utilizing a Python variable in an SQL query in Databricks:

1. Using string formatting:

variable = "some_value"
query = f"SELECT * FROM table WHERE column = '{variable}'"
spark.sql(query)

1. Using parameterization:

from pyspark.sql.functions import expr
variable = "some_value"
query = "SELECT * FROM table WHERE column = ?"
spark.sql(query).bind([expr(variable)]).show()

1. Using a temporary table:

from pyspark.sql.functions import lit
variable = "some_value"
spark.range(1).withColumn("value", lit(variable)).createOrReplaceTempView("temp_table")
query = "SELECT * FROM table WHERE column = (SELECT value FROM temp_table)"
spark.sql(query)
