Question

Want to insert all the Rows of a table in a new table with a renaming activity.
Also we have some exceptions that we shouldn’t move them.

Renaming Act : Change the char ‘_’ into ‘ ‘

Exceptions : Items that if we rename they would be duplicates in the new table.

So all the items there would be unique and renamed version of our previous table.

• Here we don’t have any integer ID’s,
• The database is SQL Server CE

---

• Our Tables : Product, tblNew
• Each with same columns : “Product”, “col1”, “col2”

Want to move the records to tblNew , our key column that we don’t want duplicates is “product”

Answer 1

INSERT INTO Table1(Column1)
    SELECT  REPLACE(OriginalColumn, '_', '')
      FROM  Table2 t2
            LEFT OUTER JOIN Table1 t1 ON t1.Column1 = REPLACE(OriginalColumn, '_', '')
     WHERE  t1.Column1 IS NULL  -- Not a duplicate Record
