### Question:
KbSqlParser { protected static int getBindArgsCount(String sql) { Set<Expression> expressionSet = findBindArgsExpressions(sql); int count = 0; for (Expression expression : expressionSet) { count += getBindArgsCount(expression); } return count; }  static String bindArgs(String sql, @Nullable Object[] bindArgs);  }### Answer:
@Test public void getBindArgsCount() throws Exception { String sql0 = "select * from person where id=? and (uid BETWEEN ? and ?) and test LIKE ? order by id"; String sql1 = "INSERT INTO person (id, name) VALUES (?, ?)"; String sql2 = "DELETE FROM person WHERE id in (?,?)"; String sql3 = "UPDATE person SET name = ? WHERE id = ?"; Assert.assertEquals(4, KbSqlParser.getBindArgsCount(sql0)); Assert.assertEquals(2, KbSqlParser.getBindArgsCount(sql1)); Assert.assertEquals(2, KbSqlParser.getBindArgsCount(sql2)); Assert.assertEquals(2, KbSqlParser.getBindArgsCount(sql3)); }
