INT8

This function is used to cast data to the INT8 data type.

Syntax

INT8 ( arg )  

arg
The value to be cast. The value has to be of a Numeric or Date & Time data type category.

Return Value

Returns the INT8 representation of the value provided.

Remarks

  • If the value falls outside of the INT8 range, an overflow error is returned.
  • Date & Time values are first converted to their underlying unix representation before being converted.
  • Conversions from floating point numbers floor the value.

Examples

This returns the INT8 representation of -1. Without data type context, numeric values are interpreted as their largest datatype. In this example, because -1 is signed it's interpreted as an INT64.

SELECT INT8(-1);

Response:

INT8(-1) [INT8]
-1

If we operate on a values that exceeds the range of INT8 the query errors.

SELECT INT8(-128);

Response:

The provided value overflows INT8
