What is local SQL?
Local SQL is the subset of the SQL-92 specification used to access dBASE, Paradox, and FoxPro tables. On receving local SQL statements from front-end applications, the Borland Database Engine (BDE) translates the statements into BDE API functions.
The local SQL language set
The SQL statements fall into two categories: Data Manipulation Language (DML) and Data Definition Language (DDL).
DML consists of SQL statements used for retrieving, inserting, updating, and deleting table data. SELECT is a DML statement.
DDL consists of SQL statements used for creating, altering, and deleting tables, and for creating and deleting indexes. CREATE TABLE and DROP INDEX are DDL statements.
For a complete introduction to ANSI-standard SQL, see one of the many available third-party books.
