icase in

The icase in match filter returns rows that contain a match of one or more specified values, regardless of the capitalization of the values.

Syntax

columnName icase in valueList

columnName - the column the filter will search for matching values.
valueList - the set of values to match on. This supports:
- a comma-separated list of variables: A icase in X, Y, Z. The filter will return true for all rows where the value in column A is equal to X, Y, or Z.
- a java array: A icase in X. The filter will return true for all rows where A is equal to at least one element of the java array X.
- a java.util.Collection: A icase in X. The filter will return true for all rows where A is equal to at least one element of the collection X.
- all other types: A icase in X. The filter will return true for all rows where A is equal to X.

Examples

The following example returns rows where Color is in the comma-separated list of values. Capitalization is ignored.

source = newTable(
    stringCol("Letter", "A", "C", "F", "B", "E", "D", "A"),
    intCol("Number", NULL_INT, 2, 1, NULL_INT, 4, 5, 3),
    stringCol("Color", "red", "blue", "orange", "purple", "yellow", "pink", "blue"),
    intCol("Code", 12, 13, 11, NULL_INT, 16, 14, NULL_INT),
)

result = source.where("Color icase in `Blue`, `Orange`")

The following example returns rows where Color is blue or Letter is a. Capitalization is ignored.

import io.deephaven.api.filter.FilterOr
import io.deephaven.api.filter.Filter

source = newTable(
    stringCol("Letter", "A", "C", "F", "B", "E", "D", "A"),
    intCol("Number", NULL_INT, 2, 1, NULL_INT, 4, 5, 3),
    stringCol("Color", "red", "blue", "orange", "purple", "yellow", "pink", "blue"),
    intCol("Code", 12, 13, 11, NULL_INT, 16, 14, NULL_INT),
)

result = source.where(FilterOr.of(Filter.from("Color icase in `Blue`", "Letter icase in `a`")))

The following example returns rows where Color is in a collection of values.

myList = ["Pink", "purple", "BLUE"]

source = newTable(
    stringCol("Letter", "A", "C", "F", "B", "E", "D", "A"),
    intCol("Number", NULL_INT, 2, 1, NULL_INT, 4, 5, 3),
    stringCol("Color", "red", "blue", "orange", "purple", "yellow", "pink", "blue"),
    intCol("Code", 12, 13, 11, NULL_INT, 16, 14, NULL_INT),
)

result = source.where("Color icase in myList")
