SQL Data Type Matrix

At my job I frequently have to translate SQL scripts between Oracle and PostgreSQL. I started making a table a while ago to help me remember how the various vendor-specific data types map to each other. It’s still in a very early state but it’s been very useful to me so far so I thought I’d put it online:

datatypematrix.org

Some planned additions:

  • MySQL
  • Search / filter
  • More detailed info
