i have a JSONObject :
{"Table1":[{"row1":"1","B":"2"},{"row2":"1","B1":"2"}],"Table2":[{"C":"1","D":"1145"},{"C":"1","D":"1145"}],"Table3":[{"E":"62","F":"1"},{"C":"1","D":"1145"}]}
how can I insert into sqlite foreach table ?
now use this code:
for (Iterator<String> iterator = mJson.keys(); iterator.hasNext(); ) {
String tableName = iterator.next();
if (mJson.optJSONArray(tableName) != null) {
resetTable(tableName);
JSONArray tableArray = mJson.optJSONArray(tableName);
for (int i = 0; i < tableArray.length(); i++) {
JSONObject tableData = tableArray.getJSONObject(i);
ContentValues Values = new ContentValues();
for (Iterator<String> iter = tableData.keys(); iter.hasNext(); ) {
String key = iter.next();
Values.put(key, tableData.get(key).toString());
}
db.insert(tableName, null, Values);
}
}
}
but i want fastest and better way
Answer
Use bulk insert:
for (Iterator<String> iterator = mJson.keys(); iterator.hasNext(); ) {
String tableName = iterator.next();
if (mJson.optJSONArray(tableName) != null) {
resetTable(tableName);
String sql = "INSERT INTO " + tableName + " VALUES (?);";
SQLiteStatement statement = db.compileStatement(sql);
db.beginTransaction();
JSONArray tableArray = mJson.optJSONArray(tableName);
for (int i = 0; i < tableArray.length(); i++) {
JSONObject tableData = tableArray.getJSONObject(i);
for (Iterator<String> iter = tableData.keys(); iter.hasNext(); ) {
String key = iter.next();
statement.clearBindings();
statement.bindString(1,tableData.get(key).toString());
statement.execute();
}
}
db.setTransactionSuccessful();
db.endTransaction();
}
}
