oci_bind_array_by_name
(PHP 5 >= 5.1.2, PECL OCI8 >= 1.2.0)
oci_bind_array_by_name — Binds a PHP array to an Oracle PL/SQL array parameter
说明
$statement
, string $name
, array &$var_array
, int $max_table_length
[, int $max_item_length = -1
[, int $type = SQLT_AFC
]] )
Binds the PHP array var_array to the Oracle
placeholder name, which points to an Oracle PL/SQL
array. Whether it will be used for input or output will be determined at
run-time.
参数
-
statement -
A valid OCI statement identifier.
-
name -
The Oracle placeholder.
-
var_array -
An array.
-
max_table_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), butSQLT_NUMtype 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.
-
返回值
成功时返回 TRUE ， 或者在失败时返回 FALSE 。

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.

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". :|
