AnalysisException: Syntax error in line 1: error when taking modulus of a value using abs() in Impala
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty height:90px;width:728px;box-sizing:border-box;
I want to take the modulus of a value when using Impala and I am aware of the abs() function. When I use this however like such
select abs(value) from table
It returns a value that is rounded to the nearest integer. The documentation found here states that I need to define the numeric_type. have tried this
select abs(float value) from table
but this gives me the following error
AnalysisException: Syntax error in line 1: ... abs(float value) from table ^ Encountered: FLOAT Expected: ALL, CASE, CAST, DEFAULT, DISTINCT, EXISTS, FALSE, IF, INTERVAL, NOT, NULL, TRUNCATE, TRUE, IDENTIFIER CAUSED BY: Exception: Syntax error
Any ideas how I set abs() to return a float?

I think you are misunderstanding the syntax. You call the function as abs(val). The return type is the same as the input type. It should work on integers, decimals, and floats.
If you want a particular type being returned, then you need to pass in that type, perhaps casting to the specific type.
The documentation is:
abs(numeric_type a)
Purpose: Returns the absolute value of the argument.
Return type: Same as the input value
Admittedly, this does look like the type should be part of the function call. But it is really using a programming language-style declaration to show the types that are expected.
