24 | =head1 NAME |
25 | |
26 | sqlt-diff - find the differences b/w two schemas |
27 | |
28 | =head1 SYNOPSIS |
29 | |
30 | For help: |
31 | |
32 | sqlt-diff -h|--help |
33 | |
34 | For a list of all valid parsers: |
35 | |
36 | sqlt -l|--list |
37 | |
38 | To diff two schemas: |
39 | |
40 | sqlt-diff [options] file_name1=parser file_name2=parser |
41 | |
42 | Options: |
43 | |
44 | -d|--debug Show debugging info |
45 | |
46 | =head1 DESCRIPTION |
47 | |
48 | sqlt-diff is a utility for creating a file of SQL commands necessary to |
49 | transform the first schema provided to the second. While not yet |
50 | exhaustive in its ability to mutate the entire schema, it will report the |
51 | following |
52 | |
53 | =over |
54 | |
55 | =item * New tables |
56 | |
57 | Using the Producer class of the target (second) schema, any tables missing |
58 | in the first schema will be generated in their entirety (fields, constraints, |
59 | indices). |
60 | |
61 | =item * Missing/altered fields |
62 | |
63 | Any fields missing or altered between the two schemas will be reported |
64 | as: |
65 | |
66 | ALTER TABLE <table_name> |
67 | [DROP <field_name>] |
68 | [CHANGE <field_name> <datatype> (<size>)] ; |
69 | |
70 | =item * Missing/altered indices |
71 | |
72 | Any indices missing or of a different type or on different fields will be |
73 | indicated. Indices that should be dropped will be reported as such: |
74 | |
75 | DROP INDEX <index_name> ON <table_name> ; |
76 | |
77 | An index of a different type or on different fields will be reported as a |
78 | new index as such: |
79 | |
80 | CREATE [<index_type>] INDEX [<index_name>] ON <table_name> |
81 | ( <field_name>[,<field_name>] ) ; |
82 | |
83 | =back |
84 | |
85 | "ALTER/DROP TABLE" and "CREATE INDEX" statements B<are not> generated by |
86 | the Producer, unfortunately, and may require massaging before being passed to |
87 | your target database. |
