Alteryx function mapping - Prophecy Documentation

While importing Alteryx workflows to Prophecy pipelines, Prophecy converts Alteryx functions into equivalent SQL functions. The SQL dialect used in imported pipelines is determined by the target platform you select during import (Databricks, BigQuery, or Snowflake). The following tables list all the Alteryx functions that Prophecy supports and their corresponding SQL functions. If a table does not specify Databricks, BigQuery, or Snowflake, functionality is equivalent for all three dialects.

Conditional

When you import conditional Alteryx functions into Prophecy, the logic of your formulas stays the same, but the syntax changes, because SQL engines use case expressions instead of IF/IIF/Switch. Prophecy’s import makes these conversions for you. When reading or debugging generated SQL, you should recognize the case functions below as the SQL equivalent of Alteryx’s conditional functions.

Alteryx Function	Equivalent SQL Function	Notes
`IF c THEN t ELSE f ENDIF`	`case when then else end`	`case_when` is equivalent to `if`; `endif` is equivalent to `END`.
`IF c THEN t ELSEIF c2 THEN t2 ELSE f ENDIF`	`case when c then t when c2 then t2 else f end`	`case_when` is equivalent to `if`; `endif` is equivalent to `end`. In Alteryx, you chain conditions with `elseif`. in SQL, each `elseif` becomes another `when … then …`.
`IIF`	`case when c then t else f end`	In Alteryx, `iff` serves as a shorthand for `if ... else`. In SQL, `iff` is equivalent to a `case` with one condition.
`SWITCH`	`case when c then t when c2 then t2 ... end`	In Alteryx, `switch` tests one case against several possibilities. In SQL, this is expressed as a `case` with multiple `when … then …` clauses.

Conversions

Alteryx provides many specialized conversion functions. SQL engines rely on general-purpose casting, encoding and decoding functions, and numeric conversion functions.

BigQuery provides safer casting via safe_cast, which returns null instead of failing.
Snowflake provides error-handling conversion functions such as try_cast and try_to_number, which return null when conversion fails.
Databricks SQL supports conv() for base conversions, but BigQuery and Snowflake do not have the same general-purpose base conversion function.

DateTime

Alteryx provides many specialized datetime functions. The SQL mapping depends on the target engine. Databricks SQL, BigQuery, and Snowflake all support broad datetime functionality, but they differ in function names, argument order, return types, format patterns, and time zone behavior.

Math

Alteryx offers a large catalog of dedicated math functions, many of which map directly to Databricks SQL. Most Alteryx functions have 1:1 equivalents, with a few cases (random integers, logs) requiring light SQL expressions to reproduce exact behavior.

Alteryx Function	Equivalent SQL Function	Notes
`ABS`	`abs()`	Exact mapping.
`ACOS`	`acos()`	Exact mapping.
`ASIN`	`asin()`	Exact mapping.
`ATAN`	`atan()`	Exact mapping.

`AverageNonNull`	`avg()`	`avg` ignores nulls by default.
`CEIL`	`ceil()`	Exact mapping.
`COS`	`cos()`	Exact mapping.

Databricks `rand()` returns a `DOUBLE` drawn uniformly from the interval `[0, 1)`, meaning it can return 0 but will never return 1. To mimic `RandInt(low, high)` exactly, use `cast(floor(rand() * (high - low + 1)) + low as int)`.

Bitwise

Alteryx uses named bitwise functions (such as BinaryAnd and BinaryOr), while SQL relies primarily on native operators (&, |, <<, >>) and a small set of helper functions. The mappings are direct, with no semantic differences.

Alteryx Function	Equivalent SQL Function	Notes
`BinaryAnd`	`\&`	No `Binary` keyword necessary in SQL.
`BinaryNot`	`bitwise_not`	No `Binary` keyword necessary in SQL.
`BinaryOr`	`\|`	No `Binary` keyword necessary in SQL.
`BinaryXOR`	`bitwiseXOR`	No `Binary` keyword necessary in SQL.

`ShiftRight`	`>>`	Exact mapping.

Range and bound functions

Range and bound functions behave similarly across SQL engines, but differences arise in how arrays, ordering, and positional logic are handled.

between works directly; syntax just shifts to SQL form.
Bound requires an explicit case statement.
Max and Min are direct equivalents.
MaxIDX and MinIDX in Alteryx identify the position of a value, but SQL engines typically use sorting or window functions (row_number() over (...)) to achieve the same result.

Databricks SQL
BigQuery
Snowflake

Alteryx Function	Equivalent SQL Function	Notes
`Between`	`between()`	In Alteryx, `Between([x], 10, 20)`; in SQL, `x between 10 and 20`.
`Bound`	`case when x < min then min when x > max then max else x end`	Databricks SQL has no single `bound` function; use a `case` expression to clamp the value inside a range.
`Max`	`max()`	Exact mapping. Nulls are ignored by default.
`MaxIDX`	`array_max()`	Applies to arrays rather than datasets. To find the row containing the max value, use `order by ... desc limit 1` or a window function.
`Min`	`min()`	Exact mapping. Nulls are ignored by default.
`MinIDX`	`array_min()`	Like `array_max()`, this applies to arrays. To find the row with the minimum value, use `order by ... asc limit 1`.

Alteryx Function	Equivalent SQL Function	Notes
`Between`	`between`	In Alteryx, `Between([x], 10, 20)`; in SQL, `x between 10 and 20`.
`Bound`	`case when x < min then min when x > max then max else x end`	BigQuery has no single `bound` function; use a `case` expression to clamp the value inside a range.

`Max`	`max()`	Exact mapping. Snowflake ignores nulls by default.
`MaxIDX`	`array_position(array(a), array_max(array(a))) - 1`	Snowflake preserves Alteryx zero-based positional behavior by subtracting 1 from the returned position.
`Min`	`min()`	Exact mapping. Snowflake ignores nulls by default.
`MinIDX`	`array_position(array(a), array_min(array(a))) - 1`	Snowflake preserves Alteryx zero-based positional behavior by subtracting 1 from the returned position.

Operators

Alteryx Function	Equivalent SQL Function	Notes
Block comment	`/` `/`	Exact mapping.
Single-line comment	`--`	`//` does not work in SQL.
Boolean `AND` or `\&\&`	`and`	`\&\&` is not supported in SQL. Use `AND`.
Boolean `NOT` or `!`	`!`	`!` is not supported in SQL. Use `NOT`.
Boolean `OR` or `\|\|`	`OR`	`\|\|` is not supported in SQL. Use `OR`.
Equality `==`, `=`	`=`	In SQL, equality is expressed as `=`, not `==`.
Non-equality `!=`	`!=`	Exact mapping.
Greater than, greater than or equal to, less than, less than or equal to	`>`, `>=`, `<`, `<=`	Exact mapping.
Addition, Subtraction, Multiplication, Division	`+`, `-`, `*`, `/`	Exact mapping.
Parentheses	`(` `)`	Exact mapping.
`value IN`	`in`	Exact mapping.
`value NOT IN`	`not in`	Exact mapping.

Specialized

Specialized functions have similar conceptual mappings across SQL engines, but differences arise in indexing, null handling, and how arrays are processed. These differences are especially important when translating positional logic from Alteryx.

Indexing: Alteryx uses zero-based indices. BigQuery and Snowflake arrays are 0-based, while Databricks SQL arrays are 1-based.
Null handling: NULL() is a callable function in Alteryx, but a literal in SQL.
TOPNIDX: In Alteryx it finds the position of the top N value; SQL engines typically use sorting and positional access to replicate this behavior.

Databricks SQL
BigQuery
Snowflake

Alteryx Function	Equivalent SQL Function	Notes
`Coalesce`	`coalesce()`	Alteryx evaluates left-to-right; Databricks SQL follows standard SQL semantics.
`GetVal`	`element_at()`	In Alteryx, `GetVal(list, index)` retrieves the element at a 0-based index. Databricks SQL arrays are 1-based, so `GetVal([x], 0)` corresponds to `element_at(x, 1)`.
`NULL`	`coalesce()` or `NULL` literal	`NULL` is a literal in SQL, not a function. Use `coalesce()` to replace nulls.
`TOPNIDX`	`array_sort()`, `element_at()`, and `array_position()`	No direct equivalent. Use array sorting plus positional lookup to approximate the behavior. For row-level ranking, use `order by` or window functions.
`UrlEncode`	`url_encode()`	Exact mapping.

Alteryx Function	Equivalent SQL Function	Notes
`Coalesce`	`coalesce()`	Exact mapping.
`GetVal`	`array[offset(index)]`	BigQuery arrays are 0-based using `offset`. `GetVal(x, 0)` becomes `x[offset(0)]`.
`NULL`	`coalesce()` or `null` literal	`null` is a literal in BigQuery SQL. Use `coalesce()` to replace nulls.
`TOPNIDX`	`array_sort()`, `array_reverse()`, `offset`, and `array_position()`	No direct equivalent. In BigQuery, you typically sort the array, optionally reverse it for descending order, then access the value with `offset(n-1)`.
`UrlEncode`	No direct equivalent	BigQuery does not have a built-in `url_encode` function; requires UDF or external processing.

Alteryx Function	Equivalent SQL Function	Notes
`Coalesce`	`coalesce()`	Exact mapping.
`GetVal`	`array(...)[i-1]`	Snowflake array access is adjusted to preserve Alteryx zero-based indexing behavior.
`NULL`	`coalesce()` or `null` literal	`null` is a literal in Snowflake SQL. Use `coalesce()` to replace nulls.
`TOPNIDX`	`array_position(array(a), reverse(array_sort(array(a)))[i+1]) - 1`	Snowflake preserves Alteryx positional semantics by sorting the array, selecting the indexed value, and subtracting 1 from the resulting position.
`UrlEncode`	`url_encode()`	Exact mapping.

String

Key differences across SQL engines:

Indexing: Databricks SQL arrays are 1-based, while BigQuery and Snowflake arrays are 0-based. Alteryx uses 0-based indexing.
Case sensitivity: All three engines are case-sensitive by default unless you normalize with functions such as lower() or upper().
Regex behavior:
- Databricks: Java regex
- BigQuery: RE2
- Snowflake: POSIX-style regular expressions
Function coverage: Some Alteryx string functions have no direct equivalent and require workarounds or UDFs.
Substring & trimming: Similar core functions exist across engines, but syntax and edge-case behavior may differ slightly.
