ISQL and Tools

An SQL statement starting immediately after a COMMIT WORK or ROLLBACK WORK statement starts a new transaction.

3.7ISQL REFERENCE

This section provides reference material for statements specific to ISQL.

This section does not include descriptions of standard SQL statements or statements specific to embedded SQL. For details on the syntax and semantics of those other SQL statements, see the c-treeSQL Reference Manual.

3.7.1@ (Execute)

Syntax

@filename

Description

Executes the SQL statements stored in the specified SQL script file. The statements specified in the file are not added to the history buffer.

Arguments

filename

The name of the script file.

Notes

The GET, START, and @ (execute) statements are similar in that they all read SQL script files. Both GET and START read an SQL script file and append the first statement in it to the history buffer. However, the START statement also executes the script statement and accepts argu- ments that it substitutes for parameter references in the script statement. The @ (execute) state- ment, on the other hand, executes all the statements in an SQL script file but does not add any of the statements to the history buffer. The @ statement does not support argument substitu- tion.

Example

The following example shows a simple ISQL script file.

Example 3-7: Sample ISQL script

connect to demodb; set echo on ;

create table stores (item_no integer, item_name char(20));
