SQLT-DIFF(1) User Contributed Perl Documentation SQLT-DIFF(1)NAMEsqlt-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=parser1 file_name2=parser2
Options:
-d|--debug Show debugging info
-t|--trace Turn on tracing for Parse::RecDescent
-c|--case-insensitive Compare tables/columns case-insensitively
--ignore-index-names Ignore index name differences
--ignore-constraint-names Ignore constraint name differences
--mysql_parser_version=<#####> Specify a target MySQL parser version
for dealing with /*! comments
--output-db=<Producer> This Producer will be used instead of one
corresponding to parser1 to format output
for new tables
--ignore-view-sql Ignore view SQL differences
--ignore-proc-sql Ignore procedure SQL differences
--no-batch-alters Do not clump multile alters to the same table into a
single ALTER TABLE statement where possible.
DESCRIPTIONsqlt-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.
