Data Passing Shell Variables in ISQL

Hi..

I am passing a variable in my shell function. I need to access it for an isql comand in the shell script.

However the isql o/p gives no results if i pass a variable in the command. The isql command works perfectly fine if i hardcore the table name.

My script is :

log=/home/../log/txt

LengthCheck()
{
tablename=$1

isql -S<server> -U<user> -P<pass> -D <db> -o $log << EOF
SELECT length,type from syscolumns
WHERE id = object_id("$tablename")
EOF

..
..
..
}

LengthCheck Employee

plz help..

Thanks,
dikki

NAME
osql - utility to test FreeTDS connections and queries SYNOPSIS
osql -S dsn -U username -P password [-I ini_dir] DESCRIPTION
osql is a diagnostic tool provided as part of FreeTDS. It is a Bourne shell script that checks and reports on your configuration files. If everything checks out OK, it invokes isql. osql works only with the isql that comes with unixODBC. OPTIONS
-S dsn the Data Source Name to which to connect, as known to odbc.ini. -U username database login name. -P password database password. -I ini_dir override odbc.ini file location. EXAMPLE
If you have an odbc.ini with a section like this: [myDSN] servername = myserver TDS_Version = 5.0 You would invoke osql as: osql -S myDSN [...] NOTES
If you can connect with "osql -S servername -U user -P passwd", your FreeTDS ODBC installation is working. osql guesses where unixODBC might look for its odbc.ini by examining the binary. This is not always an effective approach. If it doesn't work, you'll receive a report of candidate strings. Kindly pass along the output to help improve the guessing. If osql cannot intuit your odbc.ini directory, you can force the issue with the -I option. However, you're instructing osql what to test, not where unixODBC will eventually look. Your override is therefore only as good as you are. Look carefully at the error output before overriding. If you have suggestions for ways to make osql more useful as a diagnostic tool, please post them to the FreeTDS mailing list. HISTORY
osql first appeared in FreeTDS 0.65. AUTHORS
The osql utility was written by James K. Lowden doc 13 November 2011 osql(1)
