• introduced the method (NSArray *)fetchResultFieldsStructure to CMMCPResult
- it returns an array of dicts containing general information about each field of the result array of the last executed query
dict example so far for:
SELECT ucs_comp AS co FROM comp_ucs3 AS co_table
AUTO_INCREMENT_FLAG = 0;
BINARY_FLAG = 0;
BLOB_FLAG = 0;
ENUM_FLAG = 0;
MULTIPLE_KEY_FLAG = 1;
NOT_NULL_FLAG = 0;
NUM_FLAG = 0;
PART_KEY_FLAG = 1;
PRI_KEY_FLAG = 0;
SET_FLAG = 0;
UNIQUE_KEY_FLAG = 0;
UNSIGNED_FLAG = 0;
ZEROFILL_FLAG = 0;
byte_length = 30;
char_length = 10;
charset_collation = utf8_general_ci;
charset_name = utf8;
charsetnr = 33;
db = test;
decimals = 0;
flags = 16392;
max_byte_length = 4;
max_char_length = 1;
name = co;
org_name = ucs_comp;
org_table = comp_ucs3;
table = co_table;
type = VARCHAR;
typegrouping = string;
Hint: To test that new method one can add the following code after the execution of a mysql query:
NSArray *fStruct = [NSArray arrayWithArray:[theResult fetchResultFieldsStructure]];
