  2. pass variables in spark SQL, using python

    Another option if you're doing this sort of thing often or want to make your code easier to re-use is to use a map of configuration variables and the format option:

Method 1

You need to remove single quote and q25 in string formatting like this:

Q1 = spark.sql("SELECT col1 from table where col2>500 limit {}, 1".format(q25))

Update:

Based on your new queries:

spark.sql("SELECT col1 from table where col2>500 order by col1 desc limit {}, 1".format(q25))

Note that the SparkSQL does not support OFFSET, so the query cannot work.

If you need add multiple variables you can try this way:

q25 = 500
var2 = 50
Q1 = spark.sql("SELECT col1 from table where col2>{0} limit {1}".format(var2,q25))

Method 2

Another option if you’re doing this sort of thing often or want to make your code easier to re-use is to use a map of configuration variables and the format option:

configs = {"q25":10,
           "TABLE_NAME":"my_table",
           "SCHEMA":"my_schema"}
Q1 = spark.sql("""SELECT col1 from {SCHEMA}.{TABLE_NAME} 
                  where col2>500 
                  limit {q25}
               """.format(**configs))
