Bind Variables
The InformixAdaptor uses bind variables. A bind variable is a placeholder used in an SQL statement that is replaced with an actual value after the database server determines an execution plan. You use the following methods to operate on bind variables:
- bindVariableDictionaryForAttribute:value:
- mustUseBindVariableForAttribute:
- shouldUseBindVariableForAttribute:
For more information on using bind variables, see the EOSQLExpression class specification.
