Schema Name

Default Value: N/A
Example: schema_demo

String/Expression/Suggestion

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

Dropdown list

Select one of the options for this property to override the state of the Auto commit property on the account. The Auto commit at the Snap-level has three values: True, False, and Use account setting. The expected functionality for these modes are:

•  True - The Snap will execute with auto-commit enabled regardless of the value set for Auto commit in the Account used by the Snap.

•  False - The Snap will execute with auto-commit disabled regardless of the value set for Auto commit in the Account used by the Snap.

• Use account setting - The Snap will execute with Auto commit property value inherited by the Account used by the Snap.

Match data types

Default Value: Deselected

Checkbox

This property applies only when the Output fields property is provided with any field value(s).

If this property is selected, the Snap tries to match the output data types same as when the Output fields property is empty (SELECT * FROM ...). The output preview would be in the same format as the one when SELECT * FROM is implied and all the contents of the table are displayed.

Specify the maximum number of attempts to be made to receive a response. The request is terminated if the attempts do not result in a response.

Retry Interval (seconds)

Integer/Expression

Specify the time interval between two successive retry requests. A retry happens only when the previous attempt resulted in an exception.

Staging mode

Default Value: In memory
Example: On disk

Dropdown list

Required when the value in the Number of retries field is greater than 0. 

Specify the location from the following options to store input documents between retries:

• In memory: The query results are stored in the Snaplex memory. If the query is too large to fit in the memory space, it may cause the Snap to fail, choose the On disk option.

• On disk: The query results are stored on the disk in a temporary (tmp) directory that is managed by the SnapLogic platform. This directory is deleted automatically when the Snap terminates.

• Convert to lower case: Modifies the output string to lower case.

• Convert to upper case: Modifies the output string to upper case.

Dropdown list

Select one of the following three modes in which the Snap executes:

• 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.
