SAP HANA - Delete
SAP HANA - Delete
May 07, 2024
On this Page
Snap type:
Write
Description:
This Snap allows you to execute an SQL delete with the given properties.
If a SELECT query is executed, the query's results are merged into the incoming document and any existing keys will have their values overwritten. On the other hand, the original document is written if there are no results from the query.
Expected upstream Snaps: The dynamic variables used in the execute query can be defined by providing values upstream. The document generator Snaps like JSON Generator can be used upstream. Expected downstream Snaps: The Snap will output one document for each execution of Snap with data about number of documents deleted, hence any document processing Snap can be used downstream.
This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. See Configuring SAP HANA Accounts for information on setting up this type of account.
Views:
Input
This Snap has exactly one document input view. If the input view is defined, then the where clause can substitute incoming values for a given expression.
Output
This Snap has at most one document output view. If an output view is available, then the original document that was used to create the statement will be output with the status of the delete executed.
Error
This Snap has at most one document error view and produces zero or more documents in the view.
Database Write Snaps output all records of a batch (as configured in your account settings) to the error view if the write fails during batch processing.
Settings
Label
Required. The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.
Schema name
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 suggest-able and will retrieve available database schemas during suggest values.
The values can be passed using the pipeline parameters but not the upstream parameter.
Example: myschema
Default value: [None]
Table name
Required. Table name to execute the delete on.
The values can be passed using the pipeline parameters but not the upstream parameter.
Example: people
Default value: [None]
Delete condition (deletes all records from table if left blank)
This is an expression property to specify the SQL WHERE clause of the delete statement. The delete condition may also be passed via an upstream Snap or through the pipeline parameters.
Specify a valid WHERE clause for the delete condition. If you leave this field blank, the Snap deletes all the records from the table.
"EMPNO=" + $EMPNO + " and ENAME='" + $EMPNAME+ "'"
Caution
Using expressions that join strings together to create SQL queries or conditions has a potential SQL injection risk and is hence unsafe. Ensure that you understand all implications and risks involved before using concatenation of strings with '=' Expression enabled.
Default value: [None]
Number of retries
Specifies 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.
Example: 3
Default value: 0
Loading
Retry interval (seconds)
Specifies the time interval between two successive retry requests. A retry happens only when the previous attempt resulted in an exception.
Example: 10
Default value: 1
Loading
Loading
Examples
This example deletes the records from table 'USER'. After the execution of the pipeline all the user records with age 52 are deleted from table.
The delete condition specifies the condition to identify the records to be deleted.
The sample output of the Snap looks like below:

Dynamic DB queries now supported in the Execute Snap.
The SQL statement property now can be set as an expression property. When it is an expression, it will be evaluated with each input document and one SQL statement per each input document will be executed.
Known issue: When the SQL statement property is an expression, the pipeline parameters are shown in the suggest, but not the input schema.
With the SQL statement property set as an expression, the Snap can be exposed to SQL injection. Please use this feature with caution.
