8Query
Easy to build selection and selectionArgs for sql.
A SQLiteQueryBuilder.appendWhere(where)
of whereClause alternative.
Usage
For example:
A = 1 AND B = 2 OR C = 3
Before:
String selection = "A = ? and B = ? OR C = ?"; String[] selectionArgs = new String[] {
"1", "2", "3"
}
; getContentResolver().query(uri, projections, selection, selectionArgs, sortOrder);
After:
Squery squery = $.equal("A", 1).and().equal("B", 2).or().equal("C", 3);
getContentResolver().query(uri, projections, squery.selection, squery.selectionArgs, sortOrder);
// whereClause // String sql = squery.toString();
// (A = '1') AND (B = '2') OR (C = '3')
Orderby:
squery = squery.desc("D").asc("E").limit(10);
getContentResolver().query(uri, projections, squery.selection, squery.selectionArgs, squery.orderBy);
For another example about block:
(A = 1 and B = 2) OR (C = 3)
-
- Use
of()
- Use
$.of(
$.equal("A", 1).and().equal("B", 2) ).or().equal("C", 3);
-
- Use
begin()
+end()
- Use
$.begin()
.equal("A", 1).and().equal("B", 2) .end() .or().equal("C", 3);

Operators
$.in()
squery = $.in("Id", Arrays.asList("1", "2", "3"));
System.out.println(squery.toString());
// (Id IN (1,2,3))
