Returns a mixed associative/indexed array with meta information (column
name, type, precision, ...) about individual columns of the result after
the query associated with result_id.
Return Values
Table 287.
Mixed result set returned by sesam_field_array()
| Array Element |
Contents |
| int $arr["count"] |
Total number of columns in result set (or zero if this was
an "immediate" query). SESAM "multiple fields" are
"inlined" and treated like the respective number of columns.
|
| string $arr[col]["name"] |
column name for column(col), where
col is between 0 and
$arr["count"]-1. The returned value can
be the empty string (for dynamically computed
columns). SESAM "multiple fields" are "inlined" and treated
like the respective number of columns, each with the same
column name.
|
| string $arr[col]["count"] |
The "count" attribute describes the repetition factor when
the column has been declared as a "multiple field". Usually,
the "count" attribute is 1. The first column of a "multiple
field" column however contains the number of repetitions
(the second and following column of the "multiple field"
contain a "count" attribute of 1). This can be used to
detect "multiple fields" in the result set. See the example
shown in the sesam_query() description
for a sample use of the "count" attribute.
|
| string $arr[col]["type"] |
PHP variable type of the data for
column(col), where col
is between 0 and $arr["count"]-1. The
returned value can be one of
depending on the SQL type of the result. SESAM "multiple
fields" are "inlined" and treated like the respective number
of columns, each with the same PHP type.
|
| string $arr[col]["sqltype"] |
SQL variable type of the column data for
column(col), where col
is between 0 and $arr["count"]-1. The
returned value can be one of
- "CHARACTER"
- "VARCHAR"
- "NUMERIC"
- "DECIMAL"
- "INTEGER"
- "SMALLINT"
- "FLOAT"
- "REAL"
- "DOUBLE"
- "DATE"
- "TIME"
- "TIMESTAMP"
describing the SQL type of the result. SESAM "multiple
fields" are "inlined" and treated like the respective number
of columns, each with the same SQL type.
|
| string $arr[col]["length"] |
The SQL "length" attribute of the SQL variable in
column(col), where col
is between 0 and $arr["count"]-1. The
"length" attribute is used with "CHARACTER" and "VARCHAR"
SQL types to specify the (maximum) length of the string
variable. SESAM "multiple fields" are "inlined" and treated
like the respective number of columns, each with the same
length attribute.
|
| string $arr[col]["precision"] |
The "precision" attribute of the SQL variable in
column(col), where col
is between 0 and $arr["count"]-1. The
"precision" attribute is used with numeric and time data
types. SESAM "multiple fields" are "inlined" and treated
like the respective number of columns, each with the same
precision attribute.
|
| string $arr[col]["scale"] |
The "scale" attribute of the SQL variable in
column(col), where col
is between 0 and $arr["count"]-1. The
"scale" attribute is used with numeric data types. SESAM
"multiple fields" are "inlined" and treated like the
respective number of columns, each with the same scale
attribute.
