Question

So I am using the following functions to grab the datatype of certain fields in an SQL database.

$type  = mysql_field_type($result, $i);
$len   = mysql_field_len($result, $i);

I need to use these datatypes to ultimately structure another table. The problem is the returns I am getting from these functions are not valid SQL datatypes, I am getting returns like this: string (25), int (11), string (25)

Int is ok but string is not an SQL datatype, so do I need to figure out which returns need to be reformatted into correct datatypes and make functions to do that? Or am I missing another way to do it?

Answer 1

you will see that the mysql_field_type() function will return the following data as per (http://it2.php.net/mysql_field_type):

CHAR, VARCHAR, TINYTEXT, TEXT, MEDIUMTEXT, LONGTEXT, ENUM, SET: string
TINYINT, SMALLINT, MEDIUMINT, INT, INTEGER, BIGINT: int
FLOAT, DOUBLE, DECIMAL, NUMERIC: real
TIMESTAMP: timestamp
YEAR: year
DATE: date
TIME: time
DATETIME: datetime
TINYBLOB, MEDIUMBLOB, LONGBLOB, BLOB: blob

Perhaps you can rather try something like:

$table = "my_table";
$result = mysql_query("DESCRIBE TABLE `{$tabler}`");
while ($row = mysql_fetch_object($result)) {
    $field = $row->Field;
    $type = $row->Type;
}

Hope that helps.
