NAME

       sqlt-diff - find the differences b/w two schemas

SYNOPSIS

       For help:

         sqlt-diff -h|--help

       For a list of all valid parsers:

         sqlt -l|--list

       To diff two schemas:

         sqlt-diff [options] file_name1=parser file_name2=parser

       Options:

         -d|--debug   Show debugging info

DESCRIPTION

       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/DROP TABLE" and "CREATE INDEX" statements are not generated by the Producer,
       unfortunately, and may require massaging before being passed to your target database.
