I wanted to find out how to use a substitution variable in an SQL statement that would cause the user to be prompted for a value. Something similar to the ampersand (&&) in ORACLE.
For example, given the SQL statement below: SELECT <col1>,<col2>,<col3> FROM <table> WHERE <col5> = 35
I want the user to be prompted for the value in the WHERE (filter) clause, e.g. SELECT <col1>,<col2>,<col3> FROM <table> WHERE <col5> = ?
I would be glad if someone could point me in the right direction.
