This field is used along with the _SL_SCALE field for setting the precision and scale of a DECIMAL or NUMERIC field. _SL_PRECISION - Contains the result of the getPrecision() method. If you want to explicitly set a type for a column, set the DATA_TYPE field. If this type is not known to the database, the DATA_TYPE field will be used as a fallback. TYPE_NAME - The type to use for the column. The other fields of interest in the column definition are: You can also drop a column by setting the COLUMN_NAME value to null or the empty string. Changing the COLUMN_NAME value will change the name of the column in the created table. Note that if you change a column name, you do not need to change the name of the field in the row input documents. The Snap will automatically translate from the original name to the new name. For example, when changing from name to full_name, the name field in the input document will be put into the "full_name" column. The document contains the following fields:Ĭolumns - Contains the result of the getColumns() method with each column as a separate field in the object. The table metadata document that is read in by the second input view contains a dump of the JDBC DatabaseMetaData class. The document can be manipulated to affect the CREATE TABLE statement that is generated by this Snap. For example, to rename the name column to full_name, you can use a Mapper Snap that sets the path $._NAME to full_name. The extra view in the Select and Bulk Load Snaps are used to pass metadata about the table, effectively allowing you to replicate a table from one database to another. If you would like the table to be created with the same schema as a source table, you can connect the second output view of a Select Snap to the second input view of this Snap. If the table does not exist when the Snap tries to do the insert, and the Create table if not present property is selected, the table will be created with the columns and data types required to hold the values in the first input document. This property enables you to execute the Snap during the Save operation so that the output view can produce the preview data. A retry happens only when the previous attempt resulted in an exception. Specifies the time interval between two successive retry requests. When 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. If any error occurs during the download, the Snap waits for the time specified in the Retry interval and attempts to download the file again from the beginning. If the value is larger than 0, the Snap first downloads the target file into a temporary local file. Works in Ultra Pipelines if batch size is set to 1 in the Redshift account. CSV Formatter will cause an error since the output data is not a flattened Map data. Expected downstream Snaps: Any Snap which receives documents in the input view, such as JSON Formatter, Structure, Data, and so on.Expected upstream Snaps: Any Snap which produces documents in the output view, such as CSV Parser, JSON Parser, Structure, Data, and so on.Output: The output contains the status of insert operation in the database for each input record.If the error view is open, all input data in the batch are routed to the error view with the same error information. Otherwise, you may encounter an error message "Cannot find an input data which is related to the output record. Input data may contain values needed to evaluate expressions in the Object type, Output fields, and Conditions properties. Please make sure input data types match column data types in the database table. Input: Each document in the input view should contain a Map data of key-value entries.The Snap receives data from upstream component and loads the data into the selected table in the Redshift DB. SnapLogic has created the Redshift - Bulk Load Snap to address this issue, automating the use of the advised BULK insert using the COPY command. Refer to the Redshift - Bulk Load Snap for more information.
