Filter In-DB Tool

The Filter In-DB tool filters records with a basic filter or with a custom expression using the native language of the database, such as SQL. Use the Filter In-DB tool to query records and return records that meet the specified criteria.

While most In-DB tools do not require SQL commands, this tool requires SQL for more advanced processing.

Configure the tool

Select the appropriate filter type.

Basic Filter: Use the basic filter to construct a simple query on a single field in the database.

Use the drop down to select the column to filter on.

Use the drop down to select an operator to use.

Operator	Meaning
=	Equals
!=	Does not equal
>	Is greater than
>=	Is greater than or equal to
<	Is less than
<=	Is less than or equal to
IS NULL	Is a missing or unknown value
IS NOT NULL	Is not a missing or unknown value
LIKE	Is similar to a specified pattern in a column

Type in the value to complete the query.

Custom Filter: The Custom Filter acts as a SQL WHERE query. Use the custom filter to construct a more complex expression or to query from multiple fields in the database.
1. Use Insert Fields to pick from available fields to construct your expression.
2. Type the rest of the query in the box using the native language of the database.

If a query is constructed using the Basic Filter, a read-only query displays in the Custom Filter area. If the Custom Filter option is then selected, the query becomes editable.

Validate expression here at runtime: An option that sends a query to the database to report errors contained in the expression in the results window of this tool.

By default, errors are reported in the results window of downstream tools.

Output

Records that meet the specified criteria are output through the T output anchor. All other records are output through the F output anchor.
