Overview
sqlt-diff is a utility for creating a file of SQL commands necessary to transform the first schema provided to the second. While not yet exhaustive in its ability to mutate the entire schema, it will report the following
- •
-
New tables
Using the Producer class of the target (second) schema, any tables missing in the first schema will be generated in their entirety (fields, constraints, indices).
- •
-
Missing/altered fields
Any fields missing or altered between the two schemas will be reported as:
ALTER TABLE <table_name>[DROP <field_name>][CHANGE <field_name> <datatype> (<size>)] ;
- •
-
Missing/altered indices
Any indices missing or of a different type or on different fields will be indicated. Indices that should be dropped will be reported as such:
DROP INDEX <index_name> ON <table_name> ;An index of a different type or on different fields will be reported as a new index as such:
CREATE [<index_type>] INDEX [<index_name>] ON <table_name>( <field_name>[,<field_name>] ) ;
ALTER, CREATE, DROP statements are created by SQL::Translator::Producer::*, see there for support/problems.
Currently (v0.0900), only MySQL is supported by this code.
