在PostgreSQL中具有功能
Select id, regexp_split_to_table(meta_value) from metas;
日期:
1, '45,46,47'
2, '10'
3, ''
4, '12,4558,456'
需要相同的结果
1, '45'
1, '45'
1, '47'
2, '10'
3, ''
4, '12'
4, '4558'
4, '456'
Mysql有什么解决方案?
是链接One Column,但导致一列,需要两列或更多列

尝试使用substring_index函数
$('document').ready(function() {
$('#id_rental_table .add_new_form').on('click', function(e) {
e.preventDefault();
cloneForm();
return false;
});
// this not working
$('#id_rental_table .remove_new_form').on('click', function(e) {
e.preventDefault();
// console.log('remove called');
$(this).parent().parent().remove();
return false;
});
}
function cloneForm() {
var row = $('#id_rental_table tr:last');
var newRow = row.clone(true);
row.after(newRow);
var btn = row.find('button.add_new_form');
btn.html('-');
btn.removeClass('add_new_form').addClass('remove_new_form');
// even this won't wok.
btn.on('click', function(e) {
e.preventDefault();
//console.log($(this));
$(this).parent().parent().remove();
return false;
});
newRow.find('button.add_new_form').html('+');
newRow.find('select[name*=room_no]').val('').trigger('change');
}
