Access Inventory Schemas (AccessToSQL)
The following sections describe the tables that are created by SSMA when you export Access schemas to SQL Server.
Databases
Database metadata is exported to the SSMA_Access_InventoryDatabases table. This table contains the following columns:

| MacrosCount | int | The number of macros in the Access database. |
| AccessVersion | nvarchar(4000) | The Access version of the database. |
| Collation | nvarchar(4000) | The collation of the Access database. Collations determine how a database sorts and compares strings. |
| JetVersion | nvarchar(4000) | The Jet database engine version. Access databases use the underlying Jet database engine. |
| IsUpdatable | bit | Indicates if the database can be updated. If the value is 1, the database is updatable. If the value is 0, the database is read-only. |
| QueryTimeout | int | The configured ODBC query time-out value for the database, in seconds. The default is 60 seconds. |
Tables
Table metadata is exported to the SSMA_Access_InventoryTables table. This table contains the following columns:
| Column Name | Data Type | Description |
|---|---|---|
| DatabaseId | uniqueidentifier | Identifies the database that contains this table. |
| TableId | uniqueidentifier | A GUID that uniquely identifies the table. This column is also the primary key for the table. |
| TableName | nvarchar(4000) | The name of the table. |
| RowsCount | int | The number of rows in the table. |
| ValidationRule | nvarchar(4000) | The rule that defines valid input for the table. If no validation rule exists, the field will contain an empty string. |
| LinkedTable | nvarchar(4000) | Another table, if any, that is linked with the table. Linking tables allows additions, deletions, and updates to the other table by using this table. |
| ExternalSource | nvarchar(4000) | The data source, if any, that is associated with the table. If a table is linked, it has an external data source specified in this field. |
Columns
Column metadata is exported to the SSMA_Access_InventoryColumns table. This table contains the following columns:
| Column Name | Data Type | Description |
|---|---|---|
| DatabaseId | uniqueidentifier | Identifies the database that contains this column. |
| TableId | uniqueidentifier | Identifies the table that contains this column. |
| ColumnId | int | An incrementing integer that identifies the column. ColumnId is the primary key for the table. |
| ColumnName | nvarchar(4000) | The name of the column. |
| IsNullable | bit | Specifies if the column can contain null values. If the value is 1, the column can contain null values. If the value is 0, the column cannot contain null values. Note that the validation rule can also be used to prevent null values. |
| DataType | nvarchar(4000) | The Access data type of the column, such as Text or Long. |
| IsAutoIncrement | bit | Specifies if the column automatically increments integer values. If the value is 1, the integers are automatically incrementing. |
| Ordinal | smallint | The order of the column in the table, starting at zero. |
| DefaultValue | nvarchar(4000) | The default value for the column. |
| ValidationRule | nvarchar(4000) | The rule that is used to validate data added to or updated in the column. |
Indexes
Index metadata is exported to the SSMA_Access_InventoryIndexes table. This table contains the following columns:
| Column Name | Data Type | Description |
|---|---|---|
| DatabaseId | uniqueidentifier | Identifies the database that contains this index. |
| TableId | uniqueidentifier | Identifies the table that contains this index. |
| IndexId | int | An incrementing integer that identifies the index. This column is the primary key for the table. |
| IndexName | nvarchar(4000) | The name of the index. |
| ColumnsIncluded | nvarchar(4000) | Lists the columns that are included in the index. The column names are separated by a semicolon. |
| IsUnique | bit | Specifies if each item in the index must be unique. On a multi-column index, the combination of values must be unique. If the value is 1, the index enforces unique values. |
| IsPK | bit | Specifies if the index was automatically created as part of defining the primary key. |
| IsClustered | bit | Specifies if the index is clustered. A clustered index reorders the physical storage of the data. A table can have only one clustered index. |
Foreign Keys
Foreign key metadata is exported to the SSMA_Access_InventoryForeignKeys table. This table contains the following columns:
