filter
Description
Establish a named filter for an inline or dedicated data set.
Arguments
name
Name to assign to the filter.
criterion
Boolean expression establishing the filter criteria.
Valid contexts
This action may be used within the following project items: test modules, data set modules, user-defined actions
Applicable Systems/Platforms
Use of this action is supported on the following systems/platforms: Windows, Linux.
Notes
This action may be employed within either a dedicated data set or an inline data set (within the confines of a create data set/end create data set construct, in a test module or user-defined action).
The filter action associates a set of filter criteria with a name. It does not, in and of itself, have the effect of filtering data. The actual filtering of data occurs when the established filter is invoked, either by a use data set, use filter, or set data set value action.
When the filter is applied, those rows of the data set whose values do not produce a True when applied to the expression in criterion are filtered out. For example, if criterion is set to
region = 2 and period >= 2002
, the filter excludes those rows in which region is not 2, as well as those rows for which period is earlier than 2002.The following operators may be used within an expression in thecriterion argument:
Table 1. Comparison operatorsPrecedence Comparison operator Meaning 4 = equal to 4 <> not equal to 4 > greater than 4 >= greater than or equal to 4 < less than 4 <= less than or equal to
Table 2. Logical operatorsPrecedence Logical operator Meaning 5 not Value is TRUE if its operand is FALSE. 6 and Value is TRUE if and only if both sides of the and operator are TRUE. 7 or Value is TRUE if either side of the or operator is TRUE. 注意:For the full list of operator precedence, see [here](/automation-guide/action-based-testing-language/the-test-language/operator-precedence).This action supports the <ignore> modifier. If the string
<ignore>
is present as the value of any of the arguments, or any argument contains an expression that evaluates to<ignore>
, the action is skipped during execution.
Applicable Built-In Settings
The following settings are applicable to this action: remove double quotes from cells.
