Of course this cause loss of original data and can be another problem instead of providing a proper solution. ACCEPTINVCHARS parameter enables replacement of invalid UTF-8 characters with a preferred character or default '^' character. The quick but dirty solution of this problem is using ACCEPTINVCHARS COPY command parameter. Such specific characters are not supported and cause error during execution of COPY statement. In my experience, raw_field_value column has "R.stzeit" on the other hand the original CSV file has the value "R�stzeit" Select * from stl_load_errors order by starttime desc Įspecially focus on the following columns raw_line, raw_field_value and err_reason which contains error description with values causing the error. To resolve such errors following timeformat clause should be added in one of the below format into SQL COPY command: When I checked the stl_load_errors Redshift database table, I see error code 1206 with above error message for following raw data: " 17:00" If the date or datetime format you specified in COPY command differs from data within CSV file, following error will occur:ĭate value did not match format specified Īnother COPY error related with data types is " Invalid timestamp format or value " Please refer to AWS documentation for more on dateformat and timeformat strings. Or even include the time part of datetime values like SQL Redshift developers can define different formats in COPY command according to the date data in flat file. So this type of error is very easy to distinguish from others.įrom 's3://kodyaz-data-transfer/CSVDataFile.csv' If you query the import errors system table using stl_load_errors table and check for the most recent error message, in raw_line column SQL developers will see the header line entries like "Activity_TypeID,TypeLabel,TypeText,FromDate,ToDate" (these are column headers of the data source table). Invalid digit, Value 'A', Pos 0, Type: Short If data source files has header lines which displays the column names of the data itself and ignoreheader parameter is not specified in SQL COPY command, such errors will occur: In following architecture diagram, I want to show roughly the steps to move SQL Server database table data into Amazon Redshift cluster database using comma seperated CSV files stored on AWS S3 buckets.Ī very basic error which can be easily solved is trying to import header line or header lines as table data during SQL Copy command.Īmazon Redshift data import developer should specify the number of columns as ignoreheader parameter value in COPY command. For example, changes on SQL Server Import and Export Wizard execution for exporting data in CSV file format. On the other hand, some problems require changes on the source of the data. Some of the COPY errors are related with Amazon Redshift and can be easily solved on the Redshift side.
