Description

For every sql query, add a new element 'Arg'. Eg.:

slaveId = {{SELECT id FROM Person WHERE id=?}}
slaveIdArg = {{id}}

sqlInsert = {{INSERT INTO Person (name, firstName) VALUES (?,?)}}
sqlInsertArg = {{name:F:allbut}}, {{firstName:F:allbut}}
* The ...Arg definition should not be fired directly. Instead search for all (non wrapped) ',' , split, replace every by it's onw, build array with the values, fire the prepared statement.

Die oben genannten Notation hat den Nachteil das fuer alle Query Anweisungen neue Schluesselwoerter (mit 'arg' am Ende) eingefuehrt und geparst werden muessen.

Vorschlag neue Definition (passt vermutlich auch fuer Report Notation):

sqlAfter = {{ [dbIndex] (arg1, arg2) SELECT ... WHERE id=? ...}}
  • Wobei 'arg?' beliebige QFQ Variablen sein koennen.
  • Die Spaces sind optional.
  • '(' Anstelle von '[' ist wichtig um den dbIndex von den Args unterscheiden zu koennen.
  • Sollte in einem Arg ein/mehrere '(' vorkommen, werden diese oeffnend/schliessend gezaehlt/gematched/uebersprungen und bis zum naechsten ',' oder ')' geparst.
  • Bei Report koennte folgendes moeglich sein:
    10.sql = [dbIndex] (arg1, arg2) SELECT ... WHERE id=? ...

# alternative
10.arg = arg1, arg2
