filter\_by\_value(table\_name=None, view\_name='', is\_string=None, value=0, value\_str='', column\_name=None, options={"{"}{"}"})\[source]

Calculates which objects from a table has a particular value for a particular column. The input parameters provide a way to specify either a String or a Double valued column and a desired value for the column on which the filter is performed. The operation is synchronous, meaning that a response will not be returned until all the objects are fully available. The response payload provides the count of the resulting set. A new result view which satisfies the input filter restriction specification is also created with a view name passed in as part of the input payload. Although this functionality can also be accomplished with the standard filter function, it is more efficient.

Parameters

table\_name (str) –

Name of an existing table on which to perform the calculation, in \[schema\_name.]table\_name format, using standard name resolution rules.

view\_name (str) –

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 ‘’.

is\_string (bool) –

Indicates whether the value being searched for is string or numeric.

value (float) –

The value to search for. The default value is 0.

value\_str (str) –

The string value to search for. The default value is ‘’.

column\_name (str) –

Name of a column on which the filter by value would be applied.

options (dict of str to str) –

Optional parameters. Allowed keys are:

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. Allowed values are:
- true
- false
The default value is ‘false’.
collection\_name – \[DEPRECATED–please specify the containing schema for the view as part of input parameter view\_name and use GPUdb.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.

The default value is an empty dict ( {"{"}{"}"} ).

Returns

A dict with the following entries–

count (long) –

The number of records passing the value filter.

info (dict of str to str) –

Additional information. Allowed keys are:

qualified\_view\_name – The fully qualified name of the view (i.e. including the schema).

The default value is an empty dict ( {"{"}{"}"} ).
