    154 F311 Schema definition statement - Subclause 11.1, "<schema definition>"
    155 F311-01 CREATE SCHEMA - Subclause 11.1, "<schema definition>": Support for circular references in that <referential constraint definition>s in two different <table definition>s may reference columns in the other table
    156 F311-02 CREATE TABLE for persistent base tables - Subclause 11.1, "<schema definition>": A <schema element> that is a <table definition>
          - Subclause 11.3, "<table definition>": In the context of a <schema definition>
    157 F311-03 CREATE VIEW - Subclause 11.1, "<schema definition>": A <schema element> that is a <view definition>
          - Subclause 11.22, "<view definition>": In the context of a <schema definition> without the WITH CHECK OPTION clause and without support of Feature F081, "UNION and EXCEPT in views"

    162 F812 Basic flagging - Part 1, Subclause 8.1.4, "SQL flagger": With "level of flagging" specified to be Core SQL Flagging and "extent of checking" specified to be Syntax Only
    (NOTE 455 - This form of flagging identifies vendor extensions and other non-standard SQL by checking syntax only without requiring access to the catalog information.)

    164 T321 Basic SQL-invoked routines - Subclause 11.50, "<SQL-invoked routine>"
          - If Feature T041, "Basic LOB data type support", is supported, then the <locator indication> clause must also be supported
    (NOTE 456 - "Routine" is the collective term for functions, methods, and procedures. This feature requires a conforming SQLimplementation to support both user-defined functions and user-defined procedures. An SQL-implementation that conforms to Core SQL must support at least one language for writing routines; that language may be SQL. If the language is SQL, then the basic specification capability in Core SQL is the ability to specify a one-statement routine. Support for overloaded functions and procedures is not part of Core SQL.)
    165 T321-01 User-defined functions with no overloading - Subclause 11.50, "<SQL-invoked routine>": With <function specification>
    166 T321-02 User-defined stored procedures with no overloading - Subclause 11.50, "<SQL-invoked routine>": With <SQL-invoked procedure>

          - Subclause 15.1, "<call statement>"
    169 T321-05 RETURN statement - Subclause 15.2, "<return statement>", if the SQL-implementation supports SQL routines
