嵌入式SQL（英文: Embedded SQL）是一种将SQL语句直接写入C语言、COBOL、FORTRAN及Ada等编程语言源代码中的方法。借此方法，可使得应用进程拥有了访问数据以及处理数据的能力。在这一方法中，将SQL文嵌入的目标源码的语言称为宿主语言。

在1986年发布的SQL86标准中定义了对于COBOL、FORTRAN及PI/L等语言的嵌入式SQL的规范。在****年发布的SQL89规范中，定义了对于C语言的嵌入式SQL的规范。一些大型的数据库厂商发布的数据库产品中，都提供了对于嵌入式SQL的支持。比如Oracle、DB2等。

Embedded SQL is a method of combining the computing power of a programming language and the database manipulation capabilities of SQL. Embedded SQL statements are SQL statements written inline with the program source code of the host language. The embedded SQL statements are parsed by an embedded SQL preprocessor and replaced by host-language calls to a code library. The output from the preprocessor is then compiled by the host compiler. This allows programmers to embed SQL statements in programs written in any number of languages such as C/C++, COBOL and Fortran. This differs from SQL-derived programming languages that don't go through discrete preprocessors, such as PL/SQL and T-SQL.
