Queries with keyword 'IN'

[cast]

The AppendIn method of the QueryImpl class does not append commas in between values.

The following code should fix that:

private void appendIn(StringBuilder sb, String field, List params) {
sb.append("").append(field).append("");
sb.append(" ");
sb.append("IN");
sb.append(" (");
boolean quoteParam = true;
for(int i = 0; i < params.size(); i++){
if(i != 0){
sb.append(",");
}
sb.append("'").append(params.get(i)).append("'");
}
sb.append(")");
}
