# tFilterRow Standard properties
These properties are used to configure tFilterRow running in the Standard Job framework.
The Standard tFilterRow component belongs to the Processing family.
The component in this framework is available in all Talend products.
## Basic settings
| Properties | Description |
| --- | --- |
| Schema and Edit
Schema | A schema is a row description. It defines the number of fields
(columns) to be processed and passed on to the next component. When you create a Spark
Job, avoid the reserved word line when naming the
fields.
The schema of this component is built-in only.
This component offers the advantage of the
dynamic schema feature. This allows you to retrieve unknown columns from source
files or to copy batches of columns from a source without mapping each column
individually. For further information about dynamic schemas, see [Dynamic schema](https://help.qlik.com/talend/r/en-US/8.0/studio-user-guide/dynamic-schema).
This
dynamic schema feature is designed for the purpose of retrieving unknown columns of a
table and is recommended to be used for this purpose only; it is not recommended for the
use of creating tables. |
| Logical operator used to combine conditions | Select a logical operator to combine simple conditions and to
combine the filter results of both modes if any advanced conditions
are defined.
And: returns the boolean value of
*true* if all conditions are
true; otherwise *false*. For each
two conditions combined using a logical AND, the second condition is
evaluated only if the first condition is evaluated to be
true.
Or: returns the boolean value of
*true* if any condition is
true; otherwise *false*. For each
two conditions combined using a logical OR, the second condition is
evaluated only if the first condition is evaluated to be
false. |
| Conditions | Click the plus button to add as many simple conditions as needed.
Based on the logical operator selected, the conditions are evaluated
one after the other in sequential order for each row. When
evaluated, each condition returns the boolean value of *true* or *false*.
Input column: Select the column of
the schema the function is to be operated on
Function: Select the function on
the list
Operator: Select the operator to
bind the input column with the value
Value: Type in the filtered value,
between quotes if needed. |
| Use advanced mode | Select this check box when the operations you want to perform
cannot be carried out through the standard functions offered, for
example, different logical operations in the same component. In the
text field, type in the regular expression as required.
If multiple advanced conditions are defined, use a logical
operator between two conditions:
&& (logical AND): returns the boolean value
of *true* if both conditions are
true; otherwise *false*. The second
condition is evaluated only if the first condition is evaluated to
be true.
\|\| (logical OR): returns the boolean value of
*true* if either condition is
true; otherwise *false*. The second
condition is evaluated only if the first condition is evaluated to
be false. |
## Advanced settings
| Properties | Description |
| --- | --- |
| tStatCatcher Statistics | Select this check box to gather the Job processing metadata at the
Job level as well as at each component level. |
## Global Variables
| Variables | Description |
| --- | --- |
| Global Variables | ERROR\_MESSAGE: the error message generated by the
component when an error occurs. This is an After variable and it returns a string. This
variable functions only if the Die on error checkbox is
cleared, if the component has this checkbox.
NB\_LINE: the number
of rows read by an input component or transferred to an output component. This is an
After variable and it returns an integer.
NB\_LINE\_OK: the
number of rows matching the filter. This is an After variable and it returns an
integer.
NB\_LINE\_REJECTED: the number of rows rejected. This is an After
variable and it returns an integer.
A Flow variable functions during the execution of a component
while an After variable functions after the execution of the component.
To fill up a field or expression with a variable, press Ctrl+Space to access the variable list and choose the variable to use from
it.
