mdb-schema(1) Executable programs or shell commands mdb-schema(1) NAME mdb-schema - Generate schema creation DDL SYNOPSIS mdb-schema [options] [-T tablename] [-N prefix] database [backend] mdb-schema -h|--help mdb-schema --version DESCRIPTION mdb-schema is a utility program distributed with MDB Tools. It produces DDL (data definition language) output for the given database. This can be passed to another database to create a replica of the original access table format. OPTIONS -T, --table tablename Single table option. Create schema for this table only. Default is to export all tables. -N, --namespace prefix Prefix identifiers with namespace. --drop-table Issue DROP TABLE statement. --no-drop-table Don't issue DROP TABLE statement. This is the default. --not-null Issue NOT NULL constraints. This is the default. --no-not-null Don't issue NOT NULL constraints. --default-values Issue DEFAULT values. --no-default-values Don't issue DEFAULT values. This is the default. --not-empty Issue CHECK <> '' constraints. --no-not-empty Don't issue CHECK <> '' constraints. This is the default. --comments Issue COMMENT ON statements with column/table descriptions. This is the default, but it's not supported by all backends. --no-comments Don't issue COMMENT ON statements. --indexes Export INDEXes. This is the default. --no-indexes Don't export INDEXes. --relations Export foreign keys constraints. This is the default. --no-relations Don't export foreign keys constraints. --version Print the mdbtools version and exit. backend Specifies target DDL dialect. Supported values are access, sybase, oracle, postgres, mysql and sqlite. If not specified the generated DDL will be in access format. ENVIRONMENT MDB_JET3_CHARSET Defines the charset of the input JET3 (access 97) file. Default is CP1252. See iconv(1). MDBICONV Defines the output charset to use for the SQL file. Default is UTF-8. mdbtools must have been compiled with iconv. MDBOPTS Colon-separated list of options: * debug_like * debug_write * debug_usage * debug_ole * debug_row * debug_props * debug_all is a shortcut for all debug_* options * no_memo (deprecated; has no effect) * use_index (experimental; requires libmswstr) NOTES HISTORY mdb-schema first appeared in MDB Tools 0.1.

BUGS Relationships and other features may not be supported by all databases. Access datatypes are mapped to their closest counterparts in the target backend. This may not always yield an exact fit.
