Fetches multiple rows from a query into a two-dimensional array. By default, all rows are returned.
This function can be called only once for each query executed with oci_execute().
A valid OCI8 statement identifier created by oci_parse() and executed by oci_execute(), or a REF CURSOR statement identifier.
The variable to contain the returned rows.
LOB columns are returned as strings, where Oracle supports conversion.
See oci_fetch_array() for more information on how data and types are fetched.
The number of initial rows to discard when fetching the result. The default value is 0, so the first row onwards is returned.
The number of rows to return. The default is -1 meaning return all the rows from skip
+ 1 onwards.
Parameter flags
indicates the array structure and whether associative arrays should be used.
Constant | Description |
---|---|
OCI_FETCHSTATEMENT_BY_ROW | The outer array will contain one sub-array per query row. |
OCI_FETCHSTATEMENT_BY_COLUMN | The outer array will contain one sub-array per query column. This is the default. |
Arrays can be indexed either by column heading or numerically. Only one index mode will be returned.
Constant | Description |
---|---|
OCI_NUM | Numeric indexes are used for each column's array. |
OCI_ASSOC | Associative indexes are used for each column's array. This is the default. |
Use the addition operator "+" to choose a combination of array structure and index modes.
Oracle's default, non-case sensitive column names will have uppercase array keys. Case-sensitive column names will have array keys using the exact column case. Use var_dump() on output
to verify the appropriate case to use for each query.
Queries that have more than one column with the same name should use column aliases. Otherwise only one of the columns will appear in an associative array.
Returns the number of rows in output
, which may be 0 or more, or FALSE
on failure.
Using skip
is very inefficient. All the rows to be skipped are included in the result set that is returned from the database to PHP. They are then discarded. It is more efficient to use SQL to restrict the offset and range of rows in the query. See oci_fetch_array() for an example.
Queries that return a large number of rows can be more memory efficient if a single-row fetching function like oci_fetch_array() is used.
For queries returning a large number of rows, performance can be significantly improved by increasing oci8.default_prefetch or using oci_set_prefetch().
Will not return rows from Oracle Database 12c Implicit Result Sets. Use oci_fetch_array() instead.
