I am running into an issue with PHP/SQL

I tried to pass an empty array to SQL with oci_bind_array_by_name and

oci_bind_array_by_name($stid, ":c1", $array, 5, -1, SQLT_CHR);

will give me 'Maximum array length must be greater than zero' error

However, if I first detect the array length and skip obi_bind_array_by_name if array is empty, I will get error from SQL

'not all variables bound'

I need to store empty array sometimes to sql. I am not sure how to fix this. Any ideas?

我遇到了PHP / SQL的问题

我试过 使用 oci_bind_array_by_name

  oci_bind_array_by_name($ stid,“:c1”,$ array,5,-1,SQLT_CHR)将空数组传递给SQL  ; 


但是,如果我第一次检测到数组长度并跳过 obi_bind_array_by_name ,如果数组为空,我将从SQL


我有时需要将空数组存储到sql中。 我不知道如何解决这个问题。 有什么想法吗?

    You still have to bind all your variable, even if they don't have a value so for

    select * 
    from t1 
    where = :1 

    You'd still have to set :1 to a value and if you want to ignore that condition do:

    select * 
    from t1 
    where ( = '' or '' is '');

    assuming it was set to an empty string.
