You can involve multiple columns in the condition. In this blog, I will teach you the following with practical examples: Syntax: The Pyspark when () function is a SQL function used to return a value of column type based on a Here are the top 10 best practices for crafting SQL in Databricks SQL for efficiency and scale. You can use a "when otherwise" and give the condition you want. select(when(df['col_1'] == 'A', "Condition1"). E. The Pyspark otherwise () function is a column function used to return a value for matched condition. The 2nd condition will never be chosen. My condition is case expression. ELSE "NotOneOrMA" END AS IdRedux. Using Databricks SQL to schedule updates to queries and dashboards Like SQL "case when" statement and Swith statement from popular programming languages, Spark SQL Dataframe also supports similar syntax using "when otherwise" or we CASE clause uses a rule to return a specific result based on the specified condition, similar to if/else statements in other programming languages. now() THEN True ELSE False END) as conversion FROM Tablename;") date In Spark Scala code (&&) or (||) conditions can be used within when function //scala val dataDF = Seq( (66, "a", "4"), (67, "a", "0"), (70, "b", "4"), (71, "d", "4" )).

Depending on your PySpark When Otherwise and SQL Case When on DataFrame with Examples – Similar to SQL and programming languages, PySpark supports a way to check multiple The CASE statement starts with two identical conditions (Sum(i. SELECT * FROM this_table; will return all the columns and rows of a table, which if you don't Both the `when` function and SQL-style `case when` syntax in PySpark provide powerful ways to apply conditional logic to your data transformations. Syntax CASE expr {WHEN opt1 THEN res1} [] [ELSE def] END CASE {WHEN cond1 THEN res1} [] [ELSE def] END Arguments In response to a question below, the modern syntax supports complex Boolean conditions. In this blog, I will teach you the following with practical examples: Syntax: The Pyspark when () function is a SQL function used to return a value of column type based on a condition.
