/filter/bystring

URL: https://<aws.fqdn>/<aws.cluster.name>/gpudb-0/filter/bystring

Calculates which objects from a table or view match a string expression for the given string columns. Setting case_sensitive can modify case sensitivity in matching for all modes except search. For search mode details and limitations, see Full Text Search.

Input Parameter Description

Name

Type

Description

table_name

string

Name of the table on which the filter operation will be performed, in [schema_name.]table_name format, using standard name resolution rules. Must be an existing table or view.

view_name

string

If provided, then this will be the name of the view containing the results, in [schema_name.]view_name format, using standard name resolution rules and meeting table naming criteria. Must not be an already existing table or view. The default value is ''.

expression

string

The expression with which to filter the table.

mode

string

The string filtering mode to apply. See below for details.

Supported Values	Description
search	Full text search query with wildcards and boolean operators. Note that for this mode, no column can be specified in input parameter column_names; all string columns of the table that have text search enabled will be searched.
equals	Exact whole-string match (accelerated).
contains	Partial substring match (not accelerated). If the column is a string type (non-charN) and the number of records is too large, it will return 0.
starts_with	Strings that start with the given expression (not accelerated). If the column is a string type (non-charN) and the number of records is too large, it will return 0.
regex	Full regular expression search (not accelerated). If the column is a string type (non-charN) and the number of records is too large, it will return 0.

column_names

array of strings

List of columns on which to apply the filter. Ignored for search mode.

options

Optional parameters. The default value is an empty map ( {} ).

Supported Parameters (keys)

Parameter Description

create_temp_table

If true, a unique temporary table name will be generated in the sys_temp schema and used in place of input parameter view_name. This is always allowed even if the caller does not have permission to create tables. The generated name is returned in qualified_view_name. The default value is false. The supported values are:

true
false

collection_name

[DEPRECATED--please specify the containing schema for the view as part of input parameter view_name and use /create/schema to create the schema if non-existent] Name of a schema for the newly created view. If the schema is non-existent, it will be automatically created.

case_sensitive

If false then string filtering will ignore case. Does not apply to search mode. The default value is true. The supported values are:
