ISQL Statements

Example

To record the displayed output into the file called STK, enter:

ISQL> SPOOL STK ON ;

ISQL> SELECT * FROM customer ;

ISQL> SPOOL OFF ;

3.7.21START

Syntax

ST[ART] filename [ argument ] [ ... ] ;

Description

The START statement executes the first SQL statement stored in the specified script file.

Arguments

filename

The name of the script file. ISQL reads the file until it encounters a semicolon ( ; ) statement terminator.

argument …

ISQL substitutes the value of argument for parameter references in the script. Parameter refer- ences in a script are of the form &n, where n is an integer. ISQL replaces all occurrences of &1 in the script with the first argument value, all occurrences of &2 with the second argument value, and so on. The value of argument must not contain spaces or other special characters.

Notes

•In addition to executing the first statement in the script file, the START statement appends the statement (after any argument substitution) to the history buffer.

•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 arguments that it substitutes for parameter references in the script statement. The @ (execute) statement, 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 substitution.

Example

ISQL> -- Nothing in history buffer:

ISQL> history

History queue is empty.
