Snap type: | Write | |||||||
---|---|---|---|---|---|---|---|---|
Description: | This Snap executes a SQL Merge with the given properties. The documents that are provided in the input view will be merged into the provided table on the provided database. Each document on the input view is expected to be merged or created with/as a new record in the table. This Snap supports SQL Server 2008 or newer. Merges will be batched up until the account's batch size property or until the structure of the update statement changes. An update statement will change if an incoming document contains different keys than a previous document. The merge condition can only use variables, no constants or pipeline parameters. A good example for a merge condition is SALARY =$SALARY (here we use the SALARY variable of the input document). A bad example for a merge condition is SALARY = '100000' (this will not work since we validate the provided columns in the condition against the types defined in the table schema). While the expression toggle is available on the Merge Condition field, use of the expression toggle on the merge condition is not encouraged. The bad example can be rewritten by using an upstream Mapper Snap, where '10000' is mapped to the SALARY variable, which then can be used in the merge condition as defined in a good example. The same applies for pipeline parameters, which need to be mapped upstream similarly using a Mapper Snap. Expected upstream Snaps: The columns of the selected table need to be mapped upstream using a Mapper Snap. The Mapper Snap will provide the target schema,which reflects the schema of the table that is selected for the merge Snap. Expected downstream Snaps: The Snap will output one document for every record merged, hence any document processing Snap can be used downstream. Expected input: Document that conforms to the input view schema of the Snap. The input view schema is provided to an upstream Mapper Snap, based on the selected service object. Expected output: Document which represents the status of the merge operation for that document. Each merge operation is represented as one document in the output view. | |||||||

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 table names of all schemas. The property is suggestible and will retrieve available database schemas during suggest values. The values can be passed using the pipeline parameters but not the upstream parameter. Example: SYS | |||||||
Table Name | Required. The table to execute the merge on. The values can be passed using the pipeline parameters but not the upstream parameter. Example: people Default value: [None] | |||||||
Merge condition | Required. The ON condition of the merge statement. A boolean-type expression is expected. For an explanation of merge syntax, see http://en.wikipedia.org/wiki/Merge_%28SQL%29 Default value: [None] | |||||||
Identity column | Required. The table's identity column. If this is not set and the column is set to be generated always, then the merge will fail. Default value: [None] | |||||||
Execute during preview | This property enables you to execute the Snap during the Save operation so that the output view can produce the preview data. Default value: Not selected |
Examples
The following example illustrates the usage of SQL Merge Snap. In this example, we will supply two documents from upstream having customer information. We will try to merge this data into table called 'customer1'. One of the documents has the data of existing customer with an updated 'phoneno' field and other document is of new customer.
Following is the sample pipeline:
Input data is passed using the JSON Generator Snap. Following is the sample data passed:
The merge condition is applied on field 'customername' of customer1 table. Once the merge Snap execution completes, the record with customername 'John' updates its phoneno and a new record is created for customer 'Shaun'.
The sample out put looks as shown below:
