But in Redshift it did’t work as expected. What’s wrong in Redshift: Before checking why its not working, we’ll see how are we thinking to parsing it. Pass the argument into a variable. Use trim functions to remove the single quote. Use the split function to split these values. For each values put single quote in the beginning and the end. Review the Amazon Redshift Best Practices for Designing Tables to avoid poor table design, which can result in spikes in disk usage and poor query performance. Specifically, be sure to use a good distribution key to avoid skewed data, use sort keys based on query patterns, and use smaller column sizes to avoid consuming excessive memory and temporary disk space.
