        push @{ $rows{$table} } => @rows if $table;

DESCRIPTION

MySQL::Dump::Parser::XS is mysqldump parser written in C/XS. This module provides schema/data loader from mysqldump output SQL directly. No need mysqld.

METHODS

CLASS METHODS

new()

Creates a new parser instance. This manages parsing states and table's meta information in the parsing context.

INSTANCE METHODS

reset()

Re-initialize parsing context.

parse($line)

Parse a line of mysqldump output.

current_target_table()

Get current target table name in the parsing context.

columns($table_name)

Get column names as LIST for the table of $table_name. This method can get columns from already parsed tables only.

tables()

Get table names as LIST. This method can get tables from already parsed tables only.

FAQ

How to get column details?

Some mysqldump output include poor table schema information only. So if you just need rich table schema information, I suggest using DBIx::Inspector to solve the problem.
