I'm often reviewing existing databases and one of the first things I go looking for is the way they've used data types. In particular, I'm keen to know if they've used any deprecated data types (ie: ones that will/might be removed at some point). In our free SDU Tools for developers and DBAs, we added a procedure ListUseOfDeprecatedDataTypes to do just that, and to provide their details in a form that's easy to consume programmatically if you need that.
You can see how to execute it in the main image above. The procedure takes these parameters:
@DatabaseName sysname – This is the database to process
@SchemasToList nvarchar(max) – a comma-delimited list of schemas to include (ie: 'Sales,Purchasing') or the word 'ALL'
@TablesToList nvarchar(max)- a comma-delimited list of tables to include (ie: 'Customers,Orders') or the word 'ALL'
@ColumnsToList nvarchar(max) – a comma-delimited list of columns to include (ie: 'CustomerName,StreetAddress') or the word 'ALL'
One row is returned for each use of each deprecated data type.
The columns returned are SchemaName, TableName, ColumnName, DataType, and SuggestedReplacementType.
