Create and drop tables, primary indexes, and sequences
DBIxAdminCreateTable is a pure Perl module.
Database vendors supported MySQL, Oracle, Postgres, SQLite.
- Every table has a primary key
- The primary key is a unique, non-null, integer
- The primary key is a single column
- The primary key column is called ‘id’
- If a primary key has a corresponding auto-created index, the index is called ‘t_pkey’ This is true for Postgres, where declaring a column as a primary key automatically results in the creation of an associated index for that column. The index is named after the table, not after the column.
- If a table ‘t’ with primary key ‘id’ has an associated sequence, the sequence is called ‘t_id_seq’ This is true for both Oracle and Postgres, which use sequences to populate primary key columns. The sequences are named after both the table and the column.
