New submission from Ronny Pfannschmidt:
when using virtual tables, dumpiter generates a broken db script
virtual table entries must be created as master table entries
the sqlite tools dump does that correctly
however pythons iterdump seems to do that rather different and wrong
sqlite3 test.db "create virtual table test using fts4(example);"
-------------------------------
sqlite dump
PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
PRAGMA writable_schema=ON;
INSERT INTO
sqlite_master(type,name,tbl_name,rootpage,sql)VALUES('table','test','test',0,'CREATE
VIRTUAL TABLE test using fts4(example)');
CREATE TABLE 'test_content'(docid INTEGER PRIMARY KEY, 'c0example');
CREATE TABLE 'test_segments'(blockid INTEGER PRIMARY KEY, block BLOB);
CREATE TABLE 'test_segdir'(level INTEGER,idx INTEGER,start_block
INTEGER,leaves_end_block INTEGER,end_block INTEGER,root BLOB,PRIMARY KEY(level,
idx));
CREATE TABLE 'test_docsize'(docid INTEGER PRIMARY KEY, size BLOB);
CREATE TABLE 'test_stat'(id INTEGER PRIMARY KEY, value BLOB);
PRAGMA writable_schema=OFF;
COMMIT;
------------------------------
python iterdump "import sqlite3;
c=sqlite3.connect("test.db");
print("\n".join(c.iterdump()))"
BEGIN TRANSACTION;
CREATE VIRTUAL TABLE test using fts4(example);
CREATE TABLE 'test_content'(docid INTEGER PRIMARY KEY, 'c0example');
CREATE TABLE 'test_docsize'(docid INTEGER PRIMARY KEY, size BLOB);
CREATE TABLE 'test_segdir'(level INTEGER,idx INTEGER,start_block
INTEGER,leaves_end_block INTEGER,end_block INTEGER,root BLOB,PRIMARY KEY(level,
idx));
CREATE TABLE 'test_segments'(blockid INTEGER PRIMARY KEY, block BLOB);
CREATE TABLE 'test_stat'(id INTEGER PRIMARY KEY, value BLOB);
COMMIT;
