DESCRIPTION

41       sqlt-diff is a utility for creating a file of SQL commands necessary to
42       transform the first schema provided to the second.  While not yet
43       exhaustive in its ability to mutate the entire schema, it will report
44       the following
45
46       •   New tables
47
48           Using the Producer class of the target (second) schema, any tables
49           missing in the first schema will be generated in their entirety
50           (fields, constraints, indices).
51
52       •   Missing/altered fields
53
54           Any fields missing or altered between the two schemas will be
55           reported as:
56
57             ALTER TABLE <table_name>
58               [DROP <field_name>]
59               [CHANGE <field_name> <datatype> (<size>)] ;
60
61       •   Missing/altered indices
62
63           Any indices missing or of a different type or on different fields
64           will be indicated.  Indices that should be dropped will be reported
65           as such:
66
67             DROP INDEX <index_name> ON <table_name> ;
68
69           An index of a different type or on different fields will be
70           reported as a new index as such:
71
72             CREATE [<index_type>] INDEX [<index_name>] ON <table_name>
73               ( <field_name>[,<field_name>] ) ;
74
75       ALTER, CREATE, DROP statements are created by
76       SQL::Translator::Producer::*, see there for support/problems.
77
78       Currently (v0.0900), only MySQL is supported by this code.
