File contents required for emailing.
I have created three SQL scripts that are run by one central script. What I need to do is verify the output file from the three SQL scripts(KSH Scripts) is worth emailing. This I would like to do by verifiying the contents of the result file.
The contrlooing script creates the result file then the SQL scripts append to it from then on until the opreation completes.
For instance I have ecohed a line for each instance of the SQL script being run into the result file. So there are three lines minimum in the result file, what I would like to do is count the lines if ther are more that three line email the file, if ther are less just delete the file.
I am having trouble assinging a varialbe to the lines counted in the result file.
I have tried;
wc -l result_file
let line_c=$a-$b
if [ lin_c -le 3 ]; then
Email file
else
delete file
fi
HELP!!!!!

LEARN ABOUT PHP
mysql_unbuffered_query
MYSQL_UNBUFFERED_QUERY(3) 1 MYSQL_UNBUFFERED_QUERY(3)
mysql_unbuffered_query - Send an SQL query to MySQL without fetching and buffering the result rows.
SYNOPSIS
Warning
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should
be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
oSee: Buffered and Unbuffered queries
resource mysql_unbuffered_query (string $query, [resource $link_identifier = NULL])
DESCRIPTION
mysql_unbuffered_query(3) sends the SQL query $query to MySQL without automatically fetching and buffering the result rows as
mysql_query(3) does. This saves a considerable amount of memory with SQL queries that produce large result sets, and you can start working
on the result set immediately after the first row has been retrieved as you don't have to wait until the complete SQL query has been per-
formed. To use mysql_unbuffered_query(3) while multiple database connections are open, you must specify the optional parameter $link_iden-
tifier to identify which connection you want to use.
o $query
- The SQL query to execute. Data inside the query should be properly escaped.
o $
link_identifier -The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect(3) is
assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
is found or established, an E_WARNING level error is generated.
For SELECT, SHOW, DESCRIBE or EXPLAIN statements, mysql_unbuffered_query(3) returns a resource on success, or FALSE on error.
For other type of SQL statements, UPDATE, DELETE, DROP, etc, mysql_unbuffered_query(3) returns TRUE on success or FALSE on error.
Note
The benefits of mysql_unbuffered_query(3) come at a cost: you cannot use mysql_num_rows(3) and mysql_data_seek(3) on a result set
returned from mysql_unbuffered_query(3), until all rows are fetched. You also have to fetch all result rows from an unbuffered SQL
query before you can send a new SQL query to MySQL, using the same $link_identifier.
mysql_query(3).
