You can use this Snap to execute a stored procedure in a SQL Server database and writes the values of OUT parameters to the output view.

...

Info

Starting from SQL Server 2008, the result set from a Transact-SQL statement or stored procedure includes the count of the number of rows affected. This Snap fails to parse this extra information and may display an error (such as Failed to process result set). To fix the issue, add the following line to the stored procedure to turn off the output of the count: SET NOCOUNT ON

...

Snap Type

SQL Server - Stored Procedure is a Write-type Snap that executes an SQL Server stored procedure.

Field Name

Field Type

Description

Label*

 

Default Value: SQL Server - Stored Procedure
Example: SQL Server - Stored Procedure

String

Specify 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

 

Default Value: N/A
Example: schema_demo

String/Expression

Specify the schema name where the procedure resides. The property is suggestible and will return all schemas of the DB.

The values can be passed using the pipeline parameters but not the upstream parameter.

Stored Procedure Name*

Default Value: N/A
Example: addSeventeen

String/Expression

Specify the Stored Procedure to execute. The property is suggestible and will return all procedures of the DB. If a package is defined, then it will only return the procedures of that package. If a schema is defined and no package is defined, then it will return all procedures of that schema.

Parameter Values

Use this fieldset to set Parameter Values to be used in the stored procedure. The parameter values will be bound to input columns in the order they appear in the list.

Parameter Value

Default Value: N/A
Example: Suppose there is a stored procedure named createGreeting.  It has three parameters p1,p2, and p3.  p1 and p2 are input parameters of type VARCHAR2.  Then there have to be two string values provided.  The first value goes to p1 and the second to p2.

String/Expression

Specify the input parameter values for the stored procedure. If you define parameter values, you must do so in the same order as they appear in the stored procedure definition.

  • Quotation marks should not be used when setting input parameters unless they are part of the input value itself, since they are treated as escaped plain characters. For example, if the desired input value is TEST_VALUE1, the input parameter should be set as TEST_VALUE1, if you set it as "TEST_VALUE1", it will be recognized as \"TEST_VALUE1\".

  • If you do not provide any parameters in the Snap, you can still view the required input parameters in the Target Schema of the upstream Mapper Snap. The parameters are dynamically populated based on the column keys of the stored procedure; you can map the parameters and pass them as an input to the Stored Procedure Snap

Info

Bypassing Parameters

If you wish to bypass any parameter then add a blank row in its place in this section. This is required since the Snap expects the parameters in the order in which they are defined.

For example, if there are three parameters and they are defined as Pipeline parameters _empid, _empname, and _loc and you wish to by pass the parameter _empname, then the Snap should be configured as:


Pass through 


Default Value: Deselected 

Checkbox

If selected, the input document will be passed through to the output views under the key 'original'. The document will be passed to the Parameter output view, and it will also be passed to the Result Set output view if there is output sent from this view.

This property applies only to the Execute Snaps with SELECT statement or the Select Snaps. 

Number of retries

 

Default Value: 0
Example: 3

Integer/Expression

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)

 

Default Value: 1
Example: 10

Integer/Expression

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