Convert Oracle SQL syntax to MS SQL syntax

SQL Query Manager ++ has functionality to convert Oracle SQL syntax to SQL server SQL syntax.


If looking at the SQL statement below. This statement contains several parts that needs to be converted to be able to run as a SQL server syntax.


Some to mention is the functions substr, TO_CHAR, string concatenation ||, decode that is converted to case. And the Oracle Joining with =, =+ and += which is converted to Inner, Outer, Left Outer and Right outer Joins. SQL Query Manager ++ handles to convert all these differences and a lot of more complex queries.

else ‘EUR’
