Hello! I would like to store tuples consisting of two byte arrays in the database. The first byte array (which should be the primary key) is between 56 and 96 bits and the second one is of arbitrary length. I hoped to use the BIT-datatype in MySQL, but this is only up to a le...

SQL Server have the BIT data type, but this is just a basic BIT(1) which maps nice with boolean, in fact this is used as the boolean data type in sql server. Oracle, don't even have a boolean data type, so the lack of BIT it's not surprise. MySQL have a BIT similar to Postg...
MySQL - BIT - A bit represents the basic unit of data in programming languages. It can store only two values, represented as 0 or 1.
Suggested fix:In ResultSet.java modify the getNativeInt(int) method and inside the large switch() statement include a case for MysqlDefs.FIELD_TYPE_BIT and have it call getNativeBoolean(int) and depending on that returned value, return 1 if true or 0 if false. Example code: case MysqlD...
MySQL 的字符集(CHARACTER)和校对规则(COLLATION)是两个不同的概念。字符集是用来定义 MySQL 存储字符串的方式,校对规则定义了比较字符串的方式。 例如:创建一个使用utf8字符集,校验规则为utf8_bin的sql_01数据库 create database sql_01 char set utf8 ...

BIT(1)还需要至少1个字节，因此与BOOL/TINYINT相比，您不会节省任何空间。两者都取1个字节。
(hstmt1, DATA_TYPE, SQL_SMALLINT, &nParameterDataType, sizeof (nParameterDataType), &nLen))) { while (true) { memset (szParameterName, 0, _countof(szParameterName)); // Fetch data if (!SQL_SUCCEEDED (SQLFetch (hstmt1))) { break; } std::wcout << "column: " << szParameter...
I am working in an environment of Linux Redhat 3, MySQL 5.0.27 and JDBC 3.1.12. I have a Java Application using hibernate to communicate with the DB. I am having this non-consistent problem, basically there are times that when I am trying to write to columns of bit datatype I get...
