Send data from iOS On XOJO
This code works but it send only one record then have a error but k'now the error and the app close.
Any idea what is the problem
Thanks


Var sqlLocation As Text = App.mSessionURL + "/sql_fast"
Var v1,v2,v3,v4,v5,pic_as_text,er As Text
Var Rs As iOSSQLiteRecordSet
Var SqlStr As Text

SqlStr="Select * From AsambleaSocios Order BY numsocio"

Try
Rs=App.DBConn.SQLSelect(SqlStr)
Catch e As iOSSQLiteException
//ErrorLabel.Text = e.Reason
er= e.Reason
End Try

If Rs.RecordCount > 0 Then

Do

v1=Rs.Field("nombre";).TextValue
v2=Rs.Field("numsocio";).TextValue
v3=Rs.Field("fecha";).TextValue
v4=Rs.Field("hora";).TextValue
pic_as_text=Rs.Field("firma";).TextValue
v5=Rs.Field("distrito";).TextValue


Var sql As text = "INSERT INTO AsambleaSocios (nombre,numsocio,fecha,hora,firma,sync,distrito) VALUES ('"+ v1 + "','"+ v2 + "', '" + v3 + "', '" + v4 + "', '" + pic_as_text + "','Y','" +v5 + "')"

mSQLSocket.Start( App.mHost, App.mSessionID, sqlLocation, "SQLite", "ipadcrnew.db",sql)

Loop Until Rs.EOF=True

End If

like this
sql=sql + "INSERT INTO AsambleaSocios (nombre,numsocio,fecha,hora,firma,sync,distrito) VALUES ('"+ v1 + "','"+ v2 + "', '" + v3 + "', '" + v4 + "', '" + pic_as_text + "','Y','" +v5 + "');"
no works

Did you check the sql value in debugger? You should be able to copy/paste it to Valentina Studio.
Any message in Valentina Server log?

Yes, the problem with this approach.

But you can send multiple records in single INSERT:
INSERT INTO AsambleaSocios (nombre,numsocio,fecha,hora,firma,sync,distrito) VALUES ('v1','v2', 'v3', 'v4', 'pic_as_text','Y','v5'), ('2-v1','2-v2', '2-v3', '2-v4', '2-pic_as_text','Y','2-v5');

Additionally, you can use bound parameters, I'll show an example later (this would be the most efficient way).

Can't reproduce anything like that, it is possible to debug step by step the CloseConnectionSocket to find out the line with an issue.

I attached a modified project where parameters are used.


Dim params() As Auto
Dim row1() As Auto
Dim row2() As Auto

row1.Append( 10000 )
row1.Append( "first1" )
row1.Append( "last1" )
row1.Append( "000" )

row2.Append( 10001 )
row2.Append( "first2" )
row2.Append( "last2" )
row2.Append( "000" )

params.Append(row1)
params.Append(row2)

mSQLSocket.Start( _
App.mHost,_
App.mSessionID,_
sqlLocation,_
"SQLite",_
"sqlite_sakila.sqlite",_
"INSERT INTO actor ( actor_id, first_name, last_name, last_update ) VALUES ( ?1, ?2, ?3, ?4 );",_
params)


With this approach, we send a single query and pass multiple records (2 in this example).
It is the most efficient way for such a task.
