1. In Spatie\QueryBuilder, when the request parameter contains “,”, an error occurs: SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens (SQL: select count(*) as aggregate from `table` where `table`.`shipping_type` = 2 and `shipping_at_gmt` >= 2024-05-21 08:54:14 and `shipping_at_gmt` <= 2024-08-21 08:54:14 and `table`.`shipping_error_message` in (aaa)). See Figure 1

2. After changing the request parameter from “aaa,bbbb” to “aaa”, the SQL no longer throws an error. See Figure 2

3. View the generated SQL
select
count(*) as aggregate
from
`table`
where
`table`.`shipping_type` = 2
and `shipping_at_gmt` >= '2024-05-21 09:00:21'
and `shipping_at_gmt` <= '2024-08-21 09:00:21'
and `table`.`shipping_error_message` in ('aaa')
4. Print the processed query and bound parameters to check whether all parameters match the placeholders in the SQL. Confirm that there are 3 placeholders ? and 4 bound parameters. The root cause is that “aaa,bbbb” was split into 2 bound parameters because it is comma-separated. See Figure 3

print_r($builder->toSql());
print_r($builder->getBindings());
exit;
select `table`.* from `table` where `shipping_at_gmt` >= ? and `shipping_at_gmt` <= ? and `table`.`shipping_error_message` in (?) order by `operated_at_gmt` descArray

5. Decide to disable the automatic conversion of commas (,) to arrays in Spatie\QueryBuilder. Reference: Is it possible to disable a delimiter for an allowed filter? Print the processed query and bound parameters to check whether all parameters match the placeholders in the SQL. Confirm that there are 3 placeholders ? and 3 bound parameters. This matches expectations. See Figure 4

$allowedFilters[] = AllowedFilter::exact($field, null, true, false);
select `table`.* from `table` where `shipping_at_gmt` >= ? and `shipping_at_gmt` <= ? and `table`.`shipping_error_message` in (?) order by `operated_at_gmt` descArray

6. When the request parameter is “aaa,bbbb”, the SQL no longer throws an error, as expected. View the generated SQL. See Figure 5

select
count(*) as aggregate
from
`table`
where
`shipping_at_gmt` >= '2024-05-29 05:57:18'
and `shipping_at_gmt` <= '2024-08-29 05:57:18'
and `table`.`shipping_error_message` in ('aaa,bbbb')
