(PHP 5 >= 5.1.2, PHP 7, PHP 8, PECL OCI8 >= 1.2.0)

oci_bind_array_by_nameBinds a PHP array to an Oracle PL/SQL array parameter

Açıklama

oci_bind_array_by_name(
    resource $statement,
    string $param,
    array &$var,
    int $max_array_length,
    int $max_item_length = -1,
    int $type = SQLT_AFC
): bool

Binds the PHP array var to the Oracle placeholder param, which points to an Oracle PL/SQL array. Whether it will be used for input or output will be determined at run-time.

Bağımsız Değişkenler

statement

A valid OCI statement identifier.

param

The Oracle placeholder.

var

An array.

max_array_length

Sets the maximum length both for incoming and result arrays.

max_item_length

Sets maximum length for array items. If not specified or equals to -1, oci_bind_array_by_name() will find the longest element in the incoming array and will use it as the maximum length.

type

Should be used to set the type of PL/SQL array items. See list of available types below:

  • SQLT_NUM - for arrays of NUMBER.

  • SQLT_INT - for arrays of INTEGER (Note: INTEGER it is actually a synonym for NUMBER(38), but SQLT_NUM type won't work in this case even though they are synonyms).

  • SQLT_FLT - for arrays of FLOAT.

  • SQLT_AFC - for arrays of CHAR.

  • SQLT_CHR - for arrays of VARCHAR2.

  • SQLT_VCS - for arrays of VARCHAR.

  • SQLT_AVC - for arrays of CHARZ.

  • SQLT_STR - for arrays of STRING.

  • SQLT_LVC - for arrays of LONG VARCHAR.

  • SQLT_ODT - for arrays of DATE.

This function appears to work with PL/SQL associative arrays (index-by tables) but I was unable to get it to work with PL/SQL varrays

Note that it looks like you can't bind a multi-dimensional array with this method. If you try, you'll get a Notice about Array to string conversion, and your PL/SQL will end up with a one-dimensional array filled with the a lot of string values, all saying "Array". :|

We were able to get the example included for the "OCI_BIND_ARRAY_BY_NAME" to work. However, the example is NOT actually binding with a PL/SQL array of any type. It is writing data to an Oracle table named "bind_example". Notice how this table is created. The table does NOT have an array type as one of its fields. Since this is the case, there cannot be any binding to a PL/SQL array because at least one field in the table must be either a VARRAY, NESTED TABLE or ASSOCIATIVE ARRAY data type. We searched the Internet and could not find any examples that actually read from a PL/SQL array type. We were able to get data from a PL/SQL VARRAY data type, but only by using a SELECT statement.
