"PARAMETERS statement" on page 577
The READ statement reads a sequence of Interactive SQL statements from
the named file. This file can contain any valid Interactive SQL statement
including other READ statements. READ statements can be nested to any
depth. To find the command file, Interactive SQL will first search the current
directory, then the directories specified in the environment variable
SQLPATH, then the directories specified in the environment variable
PATH. If the named file has no file extension, Interactive SQL searches
each directory for the same file name with the extension
sql .
Parameters can be listed after the name of the command file. These
parameters correspond to the parameters named on the PARAMETERS
statement at the beginning of the statement file (see "PARAMETERS
statement" on page 577). Interactive SQL substitutes the corresponding
parameter wherever the source file contains
{ parameter-name }
where parameter-name is the name of the appropriate parameter.
The parameters passed to a command file can be identifiers, numbers, quoted
identifiers, or strings. When quotes are used around a parameter, the quotes
are put into the text during the substitution. Parameters which are not
identifiers, numbers, or strings (contain spaces or tabs) must be enclosed in
square brackets ([ ]). This allows for arbitrary textual substitution in the
command file.
If not enough parameters are passed to the command file, Interactive SQL
prompts for values for the missing parameters.
