| ACTION | Fix the bind variable. If this bind variable consists of quotes, check that the quotes are used correctly. For example, the old quoting rule of bind variables consisting of full object attribute names was incorrect because it can lead to ambiguous column references. Lets say we have an expression LTRIM(: A.B.C). Using the old quoting rule, this bind variable can refer to object attribute columns A.B.C, A.B.C, and A.B.C. To avoid this confusion, use the new quoting rule for object attribute bind variables, which is to quote each attribute name independently as needed. In the preceding example, if the intended object attribute column is A.B.C, then the expression rewritten as LTRIM(: A.B.C) or LTRIM(: A.B.C) will not lead to ambiguities. |
