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

       o   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).

       o   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>)] ;

       o   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.

NAME

       SQL::Translator::Producer::Sybase - Sybase producer for SQL::Translator

SYNOPSIS

	 use SQL::Translator;

	 my $t = SQL::Translator->new( parser => '...', producer => 'Sybase' );
	 $t->translate;

DESCRIPTION

       This module will produce text output of the schema suitable for Sybase.

Sybase Create Table Syntax
	 CREATE [ [ LOCAL ] { TEMPORARY | TEMP } ] TABLE table_name (
	     { column_name data_type [ DEFAULT default_expr ] [ column_constraint [, ... ] ]
	     | table_constraint }  [, ... ]
	 )
	 [ INHERITS ( parent_table [, ... ] ) ]
	 [ WITH OIDS | WITHOUT OIDS ]

       where column_constraint is:

	 [ CONSTRAINT constraint_name ]
	 { NOT NULL | NULL | UNIQUE | PRIMARY KEY |
	   CHECK (expression) |
	   REFERENCES reftable [ ( refcolumn ) ] [ MATCH FULL | MATCH PARTIAL ]
	     [ ON DELETE action ] [ ON UPDATE action ] }
	 [ DEFERRABLE | NOT DEFERRABLE ] [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ]

       and table_constraint is:

	 [ CONSTRAINT constraint_name ]
	 { UNIQUE ( column_name [, ... ] ) |
	   PRIMARY KEY ( column_name [, ... ] ) |
	   CHECK ( expression ) |
	   FOREIGN KEY ( column_name [, ... ] ) REFERENCES reftable [ ( refcolumn [, ... ] ) ]
	     [ MATCH FULL | MATCH PARTIAL ] [ ON DELETE action ] [ ON UPDATE action ] }
	 [ DEFERRABLE | NOT DEFERRABLE ] [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ]

Create Index Syntax
	 CREATE [ UNIQUE ] INDEX index_name ON table
	     [ USING acc_method ] ( column [ ops_name ] [, ...] )
	     [ WHERE predicate ]
	 CREATE [ UNIQUE ] INDEX index_name ON table
	     [ USING acc_method ] ( func_name( column [, ... ]) [ ops_name ] )
	     [ WHERE predicate ]
