Description:
I can't run a long query using SQLExecDirect.
I think that the problem is the size limit to 1K, but my query have almost 2K and is possible that I need increase size to other table.

My Query:

CREATE TABLE mytable ( 
AutoSequencial bigint(20) unsigned NOT NULL auto_increment,
Status tinyint(3) unsigned zerofill NOT NULL default 0,
CMC7 binary(15) NOT NULL default 0,
Chave binary(15) NOT NULL default 0,

PRIMARY KEY(AutoSequencial), 
KEY Numero (Numero), 
KEY CpfCnpj (CpfCnpj), 
KEY Chave (Chave),
KEY LinhaSup (Banco,Agencia,Conta,Numero)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 CHECKSUM=1;

Size=2.200 bytes

How to repeat:
run this function using MyODBC 3.51.11 and the query above.
nRet=SQLExecDirect(hStat,szQuery,SQL_NTS);

Suggested fix:
Increase the buffer limit or turn off limit.

I can't repeat this bug neither with MyODBC 3.51.12 nor with MyODBC 3.51.11.
Above is the test case

I try to run your test program and get the real problem with my code.

This sintax to create an auto_increment field is wrong :
CREATE TABLE mytable (AutoSequencial bigint(20) unsigned NOT NULL auto_increment) ENGINE=InnoDB DEFAULT CHARSET=latin1 CHECKSUM=1;

The correct sintax is:
CREATE TABLE mytable (AutoSequencial bigint(20) unsigned NOT NULL auto_increment primary key) ENGINE=InnoDB DEFAULT CHARSET=latin1 CHECKSUM=1;

or

CREATE TABLE mytable (AutoSequencial bigint(20) unsigned NOT NULL auto_increment, PRIMARY KEY(AutoSequencial)) ENGINE=InnoDB DEFAULT CHARSET=latin1 CHECKSUM=1;
