Detailed Description

A set of input parameters for const.

Calculates which objects from a table, collection, or view match a string expression for the given string columns. The options 'case_sensitive' can be used to modify the behavior for all modes except 'search'. For 'search' mode details and limitations, see Full Text Search.

Parameters

[in]	tableName_	Name of the table on which the filter operation will be performed. Must be an existing table, collection or view.
[in]	viewName_	If provided, then this will be the name of the view containing the results. Has the same naming restrictions as tables.
[in]	expression_	The expression with which to filter the table.
[in]	mode_	The string filtering mode to apply. See below for details. gpudb::filter_by_string_search: Full text search query with wildcards and boolean operators. Note that for this mode, no column can be specified in columnNames; all string columns of the table that have text search enabled will be searched. gpudb::filter_by_string_equals: Exact whole-string match (accelerated). gpudb::filter_by_string_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. gpudb::filter_by_string_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. gpudb::filter_by_string_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.
[in]	columnNames_	List of columns on which to apply the filter. Ignored for 'search' mode.
[in]	options_	Optional parameters. gpudb::filter_by_string_collection_name: Name of a collection which is to contain the newly created view. If the collection provided is non-existent, the collection will be automatically created. If empty, then the newly created view will be top-level. gpudb::filter_by_string_case_sensitive: If 'false' then string filtering will ignore case. Does not apply to 'search' mode. gpudb::filter_by_string_true gpudb::filter_by_string_false The default value is gpudb::filter_by_string_true.
