Components of an ESQL Application

ESQL constructs fall into the following categories:

• ESQL declare statements declare variables for use in other ESQL constructs. Such variables are also available for use in host-language constructs.
• ESQL executable statements result in the execution of instructions on a specified database at runtime. The executable statements are typically standard SQL statements and include Data Manipulation Language (DML) statements, Data Definition Language (DDL) statements and Data Control Language (DCL) statements.

See “ESQL Program Structure” for more details on ESQL program components.
