Function arrow::compute::kernels::comparison::like_utf8[−][src]

pub fn like_utf8<OffsetSize: StringOffsetSizeTrait>(
    left: &GenericStringArray<OffsetSize>, 
    right: &GenericStringArray<OffsetSize>
) -> Result<BooleanArray>
Expand description

Perform SQL left LIKE right operation on StringArray / LargeStringArray.

There are two wildcards supported with the LIKE operator:

  1. % - The percent sign represents zero, one, or multiple characters
  2. _ - The underscore represents a single character

For example:

use arrow::array::{StringArray, BooleanArray};
use arrow::compute::like_utf8;

let strings = StringArray::from(vec!["Arrow", "Arrow", "Arrow", "Ar"]);
let patterns = StringArray::from(vec!["A%", "B%", "A.", "A."]);

let result = like_utf8(&strings, &patterns).unwrap();
assert_eq!(result, BooleanArray::from(vec![true, false, false, true]));
