The delimiter character specified for the unloaded data.Ī quote character: " or ' (if both ESCAPE and ADDQUOTES are selected). If selected, for CHAR and VARCHAR columns in delimited unload files, an escape character (\) is placed before every occurrence of the following characters: 'Īnaplan server may ignore this setting and try to auto-detect. The format for fixedwidth_spec is: 'colID1:colWidth1,colID2:colWidth2. Because FIXEDWIDTH does not truncate data, the specification for each column in the UNLOAD query needs to be at least as long as the length of the longest entry for that column. DELIMITER is ignored if FIXEDWIDTH is specified. The FIXEDWIDTH spec is a string that specifies the number of columns and the width of the columns. Specifies FIXEDWIDTH spec., in which Redshift unloads the data to a file where each column width is a fixed length, rather than separated by a delimiter. Alternatively, specify a delimiter that is not contained in the data.Įxample: a pipe character ( | ), a comma (, ), or a tab ( \t ) If the data contains the delimiter character, you will need to specify the ESCAPE option to escape the delimiter, or use ADDQUOTES to enclose the data in double quotes. DELIMITER will be ignored if FIXEDWIDTH is specified. Single ASCII character that is used to separate fields in the output file. The Amazon S3 bucket where Amazon Redshift will write the output files must reside in the same region as your cluster. File names created by RedShift are in the format: s3:////_part_, where is the value of this property. The Snap uses S3 Bucket and S3 Folder in the RedShift Account to format the full S3 path. The prefix of AWS S3 file names which are used by Redshift to write data. In most cases, it is worthwhile to unload data in sorted order by specifying an ORDER BY clause in the query this approach will save the time required to sort the data when it is reloaded.Įxample: SELECT * FROM pany ORDER BY id You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.ĭefines a SELECT query. If there is any error, you will be able to preview the output file in the File Writer Snap for the error information. Connect a JSON Formatter and a File Writer Snaps to the error view and then execute the pipeline. The preview on this Snap will not execute the Redshift UNLOAD operation. The error view would contain error, reason, resolution and stack trace. This Snap has at most one document error view and produces zero or more documents in the view. an "entries" field with a list of S3 URL's written by the Redshift UNLOAD operation.a "unloadQuery" field with the query sent to Redshift, and. ![]()
