Substituting the Table Name in a String

Substituting the Table Name in a String

You can substitute the table name in a query. To substitute the table name, configure an input port to receive the table name from each input row. Identify the input port by name in the query and enclose the name with the tilde (~).
The following dynamic query contains a string variable, ~Table_Port~:
SELECT Emp_ID, Address from ~Table_Port~ where Dept = ‘HR’
The source might pass the following values to the Table_Port column:
Table_Port       
Employees_USA
Employees_England
Employees_Australia
The Integration Service replaces the ~Table_Port~ variable with the table name in the input port:
SELECT Emp_ID, Address from Employees_USA where Dept = ‘HR’ SELECT Emp_ID, Address from Employees_England where Dept = ‘HR’ SELECT Emp_ID, Address from Employees_Australia where Dept = ‘HR’
