Support and limitations:

Account:

This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. See Configuring Vertica Accounts for information on setting up this type of account.

Views:

Input	This Snap has exactly one input view.
Output	This Snap has at most one 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

Required. The database schema name. Selecting a schema filters the Table name list to show only those tables within the selected schema. The property is suggestible and retrieves available database schemas during suggest values.

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

Example: public

Table name

Required. The table on which to execute the insert operation.

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

Example: emp

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.

The WHERE clause of delete statement. Document field values can be substituted into the WHERE clause by providing the path. For example, $emp.empno would insert the field empno from the emp object into the query (empno == $emp.empno would become empno == 101 if $emp.empno evaluates to 101).

Specify a valid WHERE clause for the delete condition. If you leave this field blank, the Snap deletes all the records from the table.

Examples:

Without using expressions

EmpId = 12
email = 'you@example.com'

Using expressions

"EMPNO=$EMPNO and ENAME=$EMPNAME"
email = $email
emp=$emp
"emp='" + $emp + "'"
"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.

Without using expressions

EmpId = 12
email = 'you@example.com'

Using expressions

"EMPNO=$EMPNO and ENAME=$EMPNAME"
email = $email
emp=$emp
"emp='" + $emp + "'"
"EMPNO=" + $EMPNO + " and ENAME='" + $EMPNAME+ "'"

Number of retries

The maximum number of times that the process must be retried before displaying an error.

Default value: 0
Example: 2

Retry interval (seconds)

The maximum resting time in seconds between subsequent retries.

Default value: 1
Example: 2

Snap execution

Select 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.
