unsigned int mysql_field_count(MYSQL *mysql) Description Returns the number of columns for the most recent query on the connection. The normal use of this function is when mysql_store_result() returned NULL (and thus you have no result set pointer). In this case, you can call mysql_field_count() to determine whether mysql_store_result() should have produced a nonempty ...

Every left branch gets a 0 bit, every right branch gets a 1 bit. The in-memory representation of the trees are two unsigned integers per node. Each describes either a leaf value or an offset (in unsigned integers relative from this node) to another ...

Next I'll describe the physical attributes of each column in a row. The format depends entirely on the data type and the size of the column, so, for every data type, I'll give a description and an example. All the types are defined within the ...
MySQL NDB Cluster API Developer Guide :: 4.2.2.5 ClusterJ Mappings Between MySQL and Java Data Types
https://dev.mysql.com/doc/ndbapi/en/mccj-using-clusterj-mappings.html
ClusterJ provides mappings for all of the common MySQL database types to Java types. Java object wrappers of primitive types should be mapped to nullable database columns. Note Since Java does not have native unsigned data types, UNSIGNED columns ...
