Data Import Utility
rdm-import is a command-line utility that creates an RDM database from a backup created by
rdm-export or another data source in SQL, CSV or XML file format.

|--version||Display the version information|
|-q, --quiet||Quiet mode. No information will be displayed|
|--key=key||Specify the encryption
|--docroot=path||The location of the docroot directory. (See Database Storage Location)|
|-c, --commit=count||Commit per this number of rows|
|--dateformat=format||Date format in the import file|
|--timeformat=format||Time format in the import file|
|-f, --force||Overwrite an existing export database|
|-L, --locale=locale||The string collation locale the database will use. (See locale)|
|--alter||Existing database will be altered for DDL|
|-o, --output=db-uri||Name of the database to be created|
|-t, --table=table_name||Name of the table to import data into|
|--triggers-off||Turn off trigger execution on existing database|
|filename||Name of the file to be imported. Filename must have one of the following file extensions: sql, csv or xml. For CSV and XML import files, filename is assumed to be in dbname_tablename.[csv|xml] format where dbname is the name of the target database and table_name is the name of the target table, unless--output is used to specify the database name and/or--table is used to specify the table name. For an SQL import file, filename is assumed to be in dbname.sql format where dbname is the name of the target database, unless--outputis used to specify the database name.|
rdm-import imports data stored n files in comma-separated (CSV), XML or SQL format into an existing database. If the --force option is specified, all the existing data of the database will be removed before the new data are imported.
Each CSV or XML file must contain data for one table only. If the database name is specified with the
--output option, the
filename will be interpreted as the table name. Otherwise, the
filename should be
databasename_tablename[.csv|.xml]. Each SQL import file may contain data for multiple tables since each INSERT statement includes the name of the target table.
The SQL import file may include a schema definition, stored procedures and triggers. If it does,
rdm-import attempts to create a new database and stored procedures / triggers based on the definition before processing the INSERT statements. If the remote TFS location is specified with the --output option, the database will be created on that TFS.
--force option is specified without
--alter, an existing database will be dropped. This action is irreversible, even if the subsequent operation fails.
When importing the data into a new database using
rdm-import, the user must
make sure they process the CSV / XML files in the correct order. For instance,
if Table A has a foreign key that references Table B, then the file that
contains data for B must be imported before the file for A.
Importing Stored Procedures and Triggers
rdm-import included in the RDM 15.2 Enterprise package provides the capability to parse the stored procedure and trigger statements included in the SQL import file and report any syntax errors. This feature may be useful if there is a need to create a new SQL import file with your own stored procedure and/or trigger definitions or edit existing stored procedure and/or trigger definitions.
rdm-import included in the RDM 15.2 Core Cursor package does not have this capability built-in. It will simply read in the stored procedure/trigger definitions and store them in the target database.
The usage examples assume that
P.sql contains the following table and procedure definitions:
CREATE TABLE p0 ( a integer ); CREATE TABLE p1 ( b smallint ); COMMIT; INSERT INTO p0 VALUES 1; INSERT INTO p1 VALUES 11; CREATE TRIGGER p.trigger_insert_after_p0 AFTER INSERT ON p0 REFERENCING NEW ROW AS new_p0 FOR EACH ROW BEGIN ATOMIC INSERT INTO p1 VALUES new_p0.a + 10; END; ; COMMIT;
Creating and importing an RDM database
rdm-import can be used to create a new RDM database and populate it. Execute
rdm-import as follows.
$ rdm-import P.sql
--output" command-line option can be used to create and populate a database on a remote TFS as follows.
$ rdm-import --output tfs//localhost/REMOTE_P P.sql
A new database will be created under the TFS running on
