Field Name | Field Type | Description |
---|
Label* Default Value: SQL Server - Execute Example: Execute EmployeeRecords | 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. |
---|
SQL statement* Default Value: N/A Example: INSERT into SnapLogic.book (id, book) VALUES ($id,$book) | String/Expression | Specify the SQL statement to execute on the server. Learn more about how to execute SQL statements. We recommend you to add a single query in the SQL Statement field. You cannot use pipeline parameters within your SQL statement. If you need to use parameters, connect a Mapper Snap before the SQL Snap and provide the values. Avoid using non-standard words, such as GO in SQL statements, as GO is not a recognized keyword in SQL Server. Table name and column names must not be provided as bind parameters. Only values can be provided as bind parameters. Valid JSON paths that are defined in the WHERE clause for queries/statements will be substituted with values from an incoming document.
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 value | Use |
---|
Has no single quotes | Schaum Series | ' Schaum Series'
| Contains single quotes | O'Reilly's Publication
| 'O''Reilly''s Publication ' |
|
---|
Query type Default Value: Auto Example: Read | Dropdown list/Expression | Select the type of query for your SQL statement (Read or Write). When Auto is selected, the Snap tries to determine the query type automatically. If the execution result of the query is not as expected, you can change the query type to Read or Write. |
---|
Pass through Default Value: Selected | Checkbox | Select this checkbox to pass the input document to the output view under the key 'original'. This property applies only to the Execute Snaps with SELECT statement. |
---|
Ignore empty result Default Value: Deselected | Checkbox | Select this checkbox to ignore empty result; no document is written to the output view when a SELECT operation does not produce any result. If you deselect this checkbox and the Pass through checkbox is selected, the input document is passed through to the output view. |
---|
Number of retries Default Value: 0 Example: 3 | Integer/Expression | Specify the maximum number of attempts to be made to receive a response. The retry attempts the Snap must make in case there is a network failure and is unable to read the target file. The request is terminated if the attempts do not result in a response. If the Number of retries value is set to 0 (the default value), the retry option is disabled, and the Snap does not initiate a retry. The pipeline will not attempt to retry the operation in case of a failure—any failure encountered during the database operation will immediately result in the pipeline failing without any retry attempts to recover from the errors. If the Number of retries value is greater than 0, the Snap initiates a download of the target file into a temporary local file. If any error occurs during the download, the Snap waits for the time specified in the Retry interval and then attempts to download the file again from the beginning. After the download is successful, the Snap streams the data from the temporary file to the downstream pipeline. All temporary local files are deleted when they are no longer needed.
Ensure that the local drive has sufficient free disk space to store the temporary local file. |
---|
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. |
---|
Auto commit Default value: Use account setting Example: True | Dropdown list | Select one of the options for this property to override the state of the Auto commit property on the account. The Auto commit at the Snap-level has three values: True, False, and Use account setting. The expected functionality for these modes are: True - The Snap will execute with auto-commit enabled regardless of the value set for Auto commit in the Account used by the Snap. False - The Snap will execute with auto-commit disabled regardless of the value set for Auto commit in the Account used by the Snap. Use account setting - The Snap will execute with Auto commit property value inherited by the Account used by the Snap.
'Auto commit' may be enabled for certain use cases if PostgreSQL jdbc driver is used in either Redshift, PostgreSQL or generic JDBC Snap. But the JDBC driver may cause out of memory issues when Select statements are executed. In those cases, “Auto commit" in Snap property should be set to ‘False’ and the Fetch size in the “Account setting" can be increased for optimal performance. Multiexcerpt include macro |

Error | Reason | Resolution |

Failure: Batch operation failed. Error code: 102
| Incorrect syntax near 'GO'. | Rewrite the query without ‘GO’ and run it. |
Example
In this example, we have a table named "customer1" that stores user details. It has the columns: product, phoneno, customername, city, country. We will execute the query and retrieve customers with given name.
