You can use this Snap provides functionality to lookup records in the target SQL Server table and returns a selected set of fields for every matched record. The Snap executes one request per multiple input documents to avoid making a request for every input record. JSON paths can be used in the Snap properties and will have values from an incoming document substituted into the properties. However, documents missing values for a given JSON path will be written to the Snap's error view. After a query is executed, the query's results are merged into the incoming document.

...

The Snap ignores any duplicated lookup condition in the input document stream since it maintains a cache for lookup conditions internally. This Snap supports SQL Server 2008 or newer.

Anaplan ReadSnap execution

Default Value: Validate & Execute
Example: Execute only

Anaplan ReadSelect one of the three modes in which the Snap executes. Available options are:

  • Validate & Execute: Performs limited execution of the Snap, and generates a data preview during Pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during Pipeline runtime.

  • Execute only: Performs full execution of the Snap during Pipeline execution without generating preview data.

  • Disabled: Disables the Snap and all Snaps that are downstream from it.

Field Name

Schema name

Default Value: N/A
Example: schema_demo

String/Expression

Specify the database schema name. In case it is not defined, then the suggestion for the Table Name will retrieve all tables names of all schemas. The property is suggestible and will retrieve available database schemas during suggest values.

String/Expression

Specify the output field names for SQL SELECT statement. If this property is empty, the Snap selects all fields by executing the statement "SELECT * FROM ..."

Lookup conditions*

Use this fieldset to enter or select the lookup column name. The lookup conditions are created by using the lookup column name and the lookup column value. Each row will build a condition, such as lookupColumn1 = $inputField.

Each additional row will be concatenated using a logical AND. All rows together build the lookup condition being used to lookup records in the lookup table.

Value*

Default Value: N/A
Example: $email, $first, $last
