create a shell script that calls another script and and an awk script
Hi guys

I have a shell script that executes sql statemets and sends the output to a file.the script takes in parameters executes sql and sends the result to an output file.

#!/bin/sh
echo " $2 $3 $4 $5 $6 $7
isql -w400 -U$2 -S$5 -P$3 << xxx
use $4
go
print"**Changes to the table ************"
select *
from cashflow
where label = 'DEALS'
go
xxx
i also have an AWK script that takes the output produced by the script above and generates a csv file from it and sends the output to another file as CSV.
BEGIN {
count=0;
}

/^[^(]/ {
count+=1
if ( count >1 ){
for (i=1; i <= NF; i = i + 1)
printf("%s,",$i);
printf("\n");
}
}

My problem is.
1.how do i call the first script from another shell script passing in the required parameters.
2.how ho i call the AWK script after the output from above to process the file and produce a csv file.this has to be in the same script as the above.
3.my main problem is how to do the above from ONE shell script.
4.some of date being prcessed by the AWK script is in datetime format.the AWK script is seperating the day,month and year with comma.How do i make it treat 23-06-2008 as single field and not as seperate fields.

Thanks.

mdb-sql

MDBTools(1)															       MDBTools(1)

NAME

       mdb-sql - SQL interface to MDB Tools

SYNOPSIS

       mdb-sql [-HFp] [-d delimiter] [-i file] [-o file] [database]

DESCRIPTION

       mdb-sql is a utility program distributed with MDB Tools.

       mdb-sql allows querying of an MDB database using a limited SQL subset language.

OPTIONS

       -H     Supress header row.

       -F     Supress footer row.

       -p     Turn  off  pretty printing. By default results are printed in an ascii table format which looks nice but is not conducive to manipu-
	      lating the output with unix tools. This option prints output plainly in a tab separated format.

       -d     Specify an alternative column delimiter. If no delimiter is specified, columns will be delimited by a tab character if pretty print-
	      ing (-p) is turned off. If pretty printing is enabled this option is meaningless.

       -i     Specify an input file. This option allows an input file containing the SQL to be passed to mdb-sql.  See Notes.

       -o     Specify an output file. This option allows the name of an output file to be used instead of stdout.

COMMANDS

       mdb-sql in interactive mode takes some special commands.

       connect to <database>
	      If  no database was specified on the command line this command is necessary before any querys are issued. It also allows the switch-
	      ing of databases once in the tool.

       disconnect
	      Will disconnect from the current database.

       go     Each batch is sent to the parser using the 'go' command.

       reset A batch can be cleared using the 'reset' command.

       list tables
	      The list tables command will display a list of available tables in this database, similar to the mdb-tables utility on  the  command
	      line.

       describe table <table>
	      Will display the column information for the specified table.

       quit   Will exit the tool.

SQL LANGUAGE

       The  currently  implemented  SQL  subset is quite small, supporting only single table queries, no aggregates, and limited support for WHERE
       clauses. Here is a brief synopsis of the supported language.

       select:
	      SELECT [* | <column list>] FROM <table> WHERE <where clause>

       column list:
	      <column> [, <column list>]

       where clause:
	      <column> <operator> <literal> [AND <where clause>]

       operator:
	      =, =>, =<, <>, like, <, >

       literal:
	      integers, floating point numbers, or string literal in single quotes

NOTES

       When passing a file (-i) or piping output to mdb-sql the final 'go' is optional. This allow constructs like

       echo "Select * from Table1" | mdb-sql mydb.mdb

       to work correctly.

       The -i command can be passed the string 'stdin' to test entering text as if using a pipe.

ENVIRONMENT

       MDB_JET3_CHARSET
	      Defines the charset of the input JET3 (access 97) file. Default is CP1252. See iconv(1).

       MDBICONV
	      Defines the output charset. Default is UTF-8. mdbtools must have been compiled with iconv.

       MDBOPTS
	      semi-column separated list of options:

	      o  use_index

	      o  no_memo

	      o  debug_like

	      o  debug_write

	      o  debug_usage

	      o  debug_ole

	      o  debug_row

	      o  debug_props

	      o  debug_all is a shortcut for all debug_* options

       mdb-sql first appeared in MDB Tools 0.3.

AUTHORS

       The mdb-sql utility was written by Brian Bruns.

BUGS

       The supported SQL syntax is a very limited subset and deficient in several ways.
