5.1.1.3 Data types

All data types except ADB_FIELD_BLOB may be used as part of index. If you really need some other type, implement it by yourselves.

• ADB_FIELD_INT same as int in C
• ADB_FIELD_UNSIGNED_INT C unsigned int
• ADB_FIELD_LONG_LONG GNU C long long
• ADB_FIELD_DOUBLE C long double
• ADB_FIELD_STRING fixed length string
• ADB_FIELD_VSTRING variable length string, the space consumed by this type of data equals to strlen(vstring) + 2 * sizeof(int) + 1
• ADB_FIELD_BLOB binary large object, no size limit, can't be part of index
• ADB_FIELD_BLOB_STRING binary large object, no size limit, can be part of index
