NexusDB V3 Manual

Procedure Language

The procedure language in NexusDB SQL consists of a set of control statements that extends the SQL language with compound statement blocks (BEGIN .. END), SQL variable declarations, conditional statements, iterating statements and error handling. This functionality adds computational completeness to NexusDB SQL and makes it a fully programmable database language, which is particularly useful in the definition of triggers, user-defined procedures and user-defined functions.
