Table of Contents
FrontBase allows you to export a complete database to flat-files. The SQL statement has the following syntax:
WRITE ALL OUTPUT('<output directory>' [,'YES']);
All generated files will be saved in the specified output directory. The file called schema.sql contains the necessary SQL statements to recreate the database. If the 'YES' argument is supplied, a file for each base table is generated as well, holding the content data (rows) for the table. The schema.sql file will include the necessary import statements.
A flat-file holding the content data for a given table has the following lay-out:
Line 1: <schema name>.<table name> Line 2: Column count Line 3: <column #> <column name>,"~" Line 4: ... Line n: <column #> <column name>,"~\n" -- n-2 == column count Line n+1: <row data> Line n+2: -"-
A database with a single user (FB) and a single table T0 exported as:
WRITE ALL * OUTPUT('/tmp/db5', 'YES');
CREATE USER "FB"; CREATE SCHEMA "FB" AUTHORIZATION "FB" CREATE TABLE "T0"( "C0" INTEGER, "C1" INTEGER) ; COMMIT; SET SESSION AUTHORIZATION "FB"; INSERT INTO "FB"."T0" FROM 'FrontBase' INPUT('/tmp/db5/2_13'); COMMIT;
FB.T0 2 1 "C0","~" 2 "C1","~\n" 1~2~ 3~4~
