Does Access store data in fix lenght or variable length records?
Hi,
This is just for my own education and curiosity. Does anyone know if Access stores it's data records in a fixed length or variable length records / rows? I realize that the answer is some what immaterial as it works the way it does, but as I said I would like to know for my own knowledge. -- Dennis |

Does Access store data in fix lenght or variable length records?
Text fields are variable, i.e. disk storage used in any given record depends
on the number of characters actually present in the field, not the maximum number of characters defined for the field. Numeric fields (long, integer, byte, currency, single, float) are fixed width (the number of bytes for the type.) The Attributes property of the Field in the TableDef will tell you if it's variable width or not, e.g.: ? (Currentdb.TableDefs("MyTable").Fields("MyField"). Attributes AND dbVariableField) -- Allen Browne - Microsoft MVP.
