ISO/IEC 9075的这一部分规定了在编译单元中嵌入SQL语句的语法，该编译单元符合特定编程语言（宿主语言）的标准；如何导出符合特定编程的等效编译单元 语言标准。在等效的编译单元中，每个嵌入式SQL语句 已替换为宿主语言中的一个或多个语句，其中一些语句调用 SQL外部调用的过程，在执行时，其效果相当于执行 SQL语句；直接调用SQL语句的语法，以及；SQL语言，支持SQL语句的动态准备和执行。

This part of ISO/IEC 9075 specifies syntax for embedding SQL-statements in a compilation unit that otherwise conforms to the standard for a particular programming language (host language); How an equivalent compilation unit may be derived that conforms to the particular programming language standard. In that equivalent compilation unit, each embedded SQL-statement has been replaced by one or more statements in the host language, some of which invoke an SQL externally-invoked procedure that, when executed, has an effect equivalent to executing the SQL-statement; Syntax for direct invocation of SQL-statements,and; SQL language to support dynamic preparation and execution of SQL-statements.
