However, you can solve this by using aliases.,If two or more columns of the result have the same field names, the last column will take precedence. To access the other column(s) of the same name, you must use the numeric index of the column or make an alias for the column. For aliased columns, you cannot access the contents with the original column name.,Find centralized, trusted content and collaborate around the technologies you use most.,Based on your requirements, you could consider dividing your query in to two fetch statements. This would allow you to have the duplicate column names.

However, you can solve this by using aliases.

SELECT a.Name as aName, b.Name as bName FROM table a LEFT JOIN table b ON a.ID = b.TID

SQL Server allows you to alias table names to make things a little easier to read:,I took the spaces out of the names and was able to get the view created. Looks like I had an extra comma too.,This really comes in handy with multiple tables in a query:,Also I don't know whether the view you gave as an example in your question is just a basic example, but there's no point in creating a view for a single table

SELECT
t.column1, t.column2
FROM dbo.MyTable as t
WHERE t.column1 = 'a';

There are more than one table involved in a query,Column names are big or not very readable,The following SQL statement creates two aliases, one for the CustomerName column and one for the ContactName column. Note: It requires double quotation marks or square brackets if the alias name contains spaces:,Two or more columns are combined together

SELECT CustomerName,
Address,
PostalCode
FROM Customers;

With SQL, you can get information from columns in more than one table. This operation is called a join operation.,In SQL, a join operation is specified by placing the names of those tables that you want to join in the same FROM clause of a SELECT statement. ,Whenever the same column name exists in two or more tables being joined, the column name must be qualified by the table name to specify which column is being referenced. In this SELECT statement, the column name ITEM_NUMBER is defined in both tables, so it needs to be qualified by the table name. If the columns have different names, no qualification is needed.,Suppose that you want to see a list of all the suppliers and the item numbers and item names for their supplied items. The item name is not in the SUPPLIERS table; it is in the INVENTORY_LIST table. Using the common column, ITEM_NUMBER, you can see all of the columns as if they were from a single table.

SELECT SUPPLIER_NUMBER, SAMPLECOLL.INVENTORY_LIST.ITEM_NUMBER, ITEM_NAME
FROM SAMPLECOLL.SUPPLIERS, SAMPLECOLL.INVENTORY_LIST
WHERE SAMPLECOLL.SUPPLIERS.ITEM_NUMBER = SAMPLECOLL.INVENTORY_LIST.ITEM_NUMBER
