Oracle - Update

Field Name

Field Type

Description

Label*

Default ValueSnowflake - Update
Example: Load Employee Tables

String

Specify a unique name for the Snap. You can modify this to be more appropriate, especially if you have more than one of the same Snap in your pipeline.

SQL Statements*

Default Value: N/A

Example: INSERT into SnapLogic.book (id, book) VALUES ($id,$book)

String/Expression

Specify the Snowflake SQL statement to execute on the server. Provide the queries to be executed by the Snap. End each query with a semi-colon, except the last query. To add another query, click the + to add a row and there add the query. 

Using Where Clauses

Valid JSON paths that are defined in the WHERE clause for queries/statements are substituted with values from an incoming document. If the error view is enabled, documents are written to the error view if the document is missing a value to be substituted into the query/statement. 

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+ "'"

Note

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.

Info

Single quotes in values must be escaped

Any relational database (RDBMS) treats single quotes (') as special symbols. So, single quotes in the data or values passed through a DML query may cause the Snap to fail when the query is executed. Ensure that you pass two consecutive single quotes in place of one within these values to escape the single quote through these queries.

For example:

If String To pass this valueUse
Has no single quotes
Schaum Series
'Schaum Series'
Contains single quotes
O'Reilly's Publication
'O''Reilly''s Publication'

Session auto-commit

Default Value: Selected

Checkbox

Select this to enable the session's auto-commit. This is useful when using DDL queries since the changes made by such queries cannot be rolled back if the Snap/pipeline fails. If deselected, changes made by DML queries can be rolled back or changes made by DML queries after a DDL queries can be rolled back.

Use Result Query

Default Value: Deselected

Checkbox

Select this property to write the result of each of the query execution, in case of multiple queries, to Snap's output view after the successful execution. The output of the Snap will be enclosed within the key, Result Query and the value will be the actual output produced by the SQL query. 

The option would allow users to effectively track the query's execution by clearly indicating the successful executions and the number of records affected, if any, after the execution.

Manage Queued Queries

Default Value: Continue to execute queued queries when pipeline is stopped or if it fails
Example: Cancel queued queries when the Pipeline is stopped or if it fails

Drowpdown list

Select this property to decide whether the Snap should continue or cancel the execution of the queued Snowflake Execute SQL queries when you stop the pipeline.

If you select Cancel queued queries when the Pipeline is stopped or if it fails, then the read queries under execution are canceled, whereas the write type of queries under execution is not canceled. Snowflake internally determines which queries are safe to be canceled and cancels those queries.
