    !> Caution: Preview Feature This feature is considered a preview feature in the provider, regardless of the state of the resource in Snowflake. We do not guarantee its stability. It will be reworked and marked as a stable feature in future releases. Breaking changes are expected, even without bumping the major version. To use this feature, add the relevant feature name to preview_features_enabled field in the provider configuration. Please always refer to the Getting Help section in our Github repo to best determine how to get help for your questions.

    Applies a masking policy to a table column.

    Only one masking policy may be applied per table column, hence only one snowflake.TableColumnMaskingPolicyApplication resources may be present per table column. Using two or more snowflake.TableColumnMaskingPolicyApplication resources for the same table column will result in the last one overriding any previously applied masking policies and unresolvable diffs in pulumi preview.

    When using this resource to manage a table column’s masking policy make sure to ignore changes to the column’s masking policy in the table definition, otherwise the two resources would conflict. See example below.

    Example Usage

    import * as pulumi from "@pulumi/pulumi";
import * as snowflake from "@pulumi/snowflake";

const policy = new snowflake.MaskingPolicy("policy", {
    name: "EXAMPLE_MASKING_POLICY",
    database: "EXAMPLE_DB",
    schema: "EXAMPLE_SCHEMA",
    valueDataType: "VARCHAR",
    maskingExpression: "case when current_role() in ('ANALYST') then val else sha2(val, 512) end",
    returnDataType: "VARCHAR",
});
// Table is created by the default provider
const table = new snowflake.Table("table", {
    database: "EXAMPLE_DB",
    schema: "EXAMPLE_SCHEMA",
    name: "table",
    columns: [{
        name: "secret",
        type: "VARCHAR(16777216)",
    }],
});
const application = new snowflake.TableColumnMaskingPolicyApplication("application", {
    table: table.fullyQualifiedName,
    column: "secret",
    maskingPolicy: policy.fullyQualifiedName,
