SQLDAOLoader.mdb

This sample shows how to modify the structure of a Back-End database using SQL DDL (data definition language) statements and DAO code.  This sample does much the same as "SQLLoader.mdb", but does not require text files to hold the SQL.  Further, it utilizes DAO to accomplish some tasks that Access SQL does not allow, like Default Values (and other field attributes), creating Autonumber and Hyperlink fields, and modifying Field Names.

All of the code is stored in modules this sample and behind this form.  The changes are stored in the UpdateSteps table also in this database.  Each record in UpdateSteps has the name of a subroutine and the necessary arguments.  They are as follows:

RunSQLDDL: a SQL String
RunModifyFieldName: Tablename, OldFieldName, NewFieldName
RunSetDefaultValue:Tablename, FieldName, DefaultValue
RunSetRequired: Tablename, FieldName, True/False
RunSetZeroLength: Tablename, FieldName, True/False
RunCreateAutoNumber:Tablename, FieldName
RunCreateHyperText:Tablename, FieldName
RunSetAutonumberPrimaryKey: Tablename, FieldName

Notes: 
Not ALL table properties are addressed above (ValidationRule and ValidationRuleText being two), but the process would be similar.  Autonumber and Hypertext attributes cannot be set programmatically after the table has been appended to the Tables collection.  Therefore, you have to create the field and set the Autonumber (or hypertext) attribute at the same time.   THEN set the primary key constraint.
