OCIBindByName() OCIBindObject() OCIBindDynamic() OCIBindArrayOfStruct() to bind the address of each input variable (or PL/SQL output variable) or array to each placeholder in the statement. A statement can also be prepared for execution with OCIStmtPrepare2(), an enhanced version of OCIStmtPrepare() introduced to support statement caching. Execute. Call OCIStmtExecute() to execute the statement. For DDL statements, no further steps are necessary. Describe, if necessary. Describe the select-list items, if necessary, using OCIParamGet() and OCIAttrGet(). This is an optional step; it is not required if the number of select-list items and the attributes of each item (such as its length and datatype) are known at compile time. Define, if necessary. For queries, perform one or more define calls to OCIDefineByPos(), OCIDefineObject(), OCIDefineDynamic(), or OCIDefineArrayOfStruct() to define an output variable for each select-list item in the SQL statement. Note that you do not use a define call to define the output variables in an anonymous PL/SQL block. You have done this when you have bound the data. Fetch, if necessary.
