The older “postgres8” and “mysql5” values are still accepted for backwards- compatibility. So, in most cases, the software application can be functioning with many databases without modification to source code. Object that performs the connection to the database, executes SQL statements and has a set of utility functions for standardising the format of SQL statements for issues such as concatenation and date formats. For that matter, we should probably change the recommended dbtypes from “mysql5” and “postgres8” to just “mysql” and “postgres”. For example a timestamp type is called datetime in one database and time in another. So, if you go for oysters and I go for ersters, I’ll order oysters and cancel the ersters.

For example a timestamp type is called datetime in one database and time in another. If you enter “mysql” as your dbtype, Mahara checks for the presence of mysqli and uses that as your driver if it is present. There are two ways we could go about this gracefully: Email me about changes to this bug report. Be forewarned that not all databases support the two functions.
