icase not in

The icase not in match filter returns rows that do not contain a match of one or more specified values, regardless of the capitalization of the values.

Syntax​

columnName icase not in valueList
  • columnName - the column the filter will search for non-matching values.
  • valueList - the set of values to remove. This supports:
    • a comma-separated list of values: A icase not in X, Y, Z. The filter will return true for all rows where the value in column A is not equal to X, Y, and Z.
    • a java array: A icase not in X. The filter will return true for all rows where A is not equal to every element of the java array X.
    • a java.util.Collection: A icase not in X. The filter will return true for all rows where A is not equal to every element of the collection X.
  • all other types: A icase not in X. The filter will return true for all rows where A is not equal to X.

Examples​

The following example returns rows where Color is not in the comma-separated list of values. Capitalization is ignored.

from deephaven import new_table
from deephaven.column import string_col, int_col
from deephaven.constants import NULL_INT

source = new_table(
    [
        string_col("Letter", ["A", "C", "F", "B", "E", "D", "A"]),
        int_col("Number", [NULL_INT, 2, 1, NULL_INT, 4, 5, 3]),
        string_col(
            "Color", ["red", "blue", "orange", "purple", "yellow", "pink", "blue"]
        ),
        int_col("Code", [12, 14, 11, NULL_INT, 16, 14, NULL_INT]),
    ]
)


result = source.where(filters=["Color icase not in `Blue`, `Orange`"])

The following example returns rows where Color is not blue or Letter is not a. Capitalization is ignored.

from deephaven import new_table
from deephaven.column import string_col, int_col
from deephaven.constants import NULL_INT

source = new_table(
    [
        string_col("Letter", ["A", "C", "F", "B", "E", "D", "A"]),
        int_col("Number", [NULL_INT, 2, 1, NULL_INT, 4, 5, 3]),
        string_col(
            "Color", ["red", "blue", "orange", "purple", "yellow", "pink", "blue"]
        ),
        int_col("Code", [12, 14, 11, NULL_INT, 16, 14, NULL_INT]),
    ]
)

result = source.where_one_of(
    filters=["Color icase not in `Blue`", "Letter icase not in `a`"]
)

The following example returns rows where Color is not in a collection of values.

from deephaven import new_table
from deephaven.column import string_col, int_col
from deephaven.constants import NULL_INT

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

source = new_table(
    [
        string_col("Letter", ["A", "C", "F", "B", "E", "D", "A"]),
        int_col("Number", [NULL_INT, 2, 1, NULL_INT, 4, 5, 3]),
        string_col(
            "Color", ["red", "blue", "orange", "purple", "yellow", "pink", "blue"]
        ),
        int_col("Code", [12, 14, 11, NULL_INT, 16, 14, NULL_INT]),
    ]
)
result = source.where(filters=["Color icase not in my_list"])
