file content as a part of an if-statement

Hello,
I have following problem.
I have the result of a database request. I preparated the result via sed, etc. as a string in a file.
The string in the file is:
($3==1 || $3==2 || $3==3 || $3==4)
Now I want to use the String as a command in an if-statement.
So I assigned the string to a variable:
ABC=$(<dir/file)

So far - so good:
echo $ABC gives me as a result: ($3==1 || $3==2 || $3==3 || $3==4)

But with nawk it doesn't work.

For clarification: If I would use the string directly (and so static), my awk would be written like here:

#If we find the values 1,2,3 or 4 in column 3, so change the value in column 4 into 10 in the relevant rows.
nawk '{FS=";";OFS=";"; if ($3==1 || $3==2 || $3==3|| $3==4) {$5=10}; print $0}' dir/file1.txt > dir/file2.txt

But dynamically it doesn't work. My idea was following:

nawk '{FS=";";OFS=";"; if ($ABC) {$5=10}; print $0}' dir/file1.txt > dir/file2.txt

I tested everything, with echo $ABC, cat, different brackets... but without success.

Is anybody able to help me and explain to me what I have to change, please?

Thanks a lot and Kind Regards
Dr_Aleman

DB2_NEXT_RESULT(3)							 1							DB2_NEXT_RESULT(3)

db2_next_result - Requests the next result set from a stored procedure

SYNOPSIS
resource db2_next_result (resource $stmt) DESCRIPTION
A stored procedure can return zero or more result sets. While you handle the first result set in exactly the same way you would handle the results returned by a simple SELECT statement, to fetch the second and subsequent result sets from a stored procedure you must call the db2_next_result(3) function and return the result to a uniquely named PHP variable. PARAMETERS
o $stmt - A prepared statement returned from db2_exec(3) or db2_execute(3). RETURN VALUES
Returns a new statement resource containing the next result set if the stored procedure returned another result set. Returns FALSE if the stored procedure did not return another result set. EXAMPLES
Example #1 Calling a stored procedure that returns multiple result sets In the following example, we call a stored procedure that returns three result sets. The first result set is fetched directly from the same statement resource on which we invoked the CALL statement, while the second and third result sets are fetched from state- ment resources returned from our calls to the db2_next_result(3) function. <?php $conn = db2_connect($database, $user, $password); if ($conn) { $stmt = db2_exec($conn, 'CALL multiResults()'); print "Fetching first result set "; while ($row = db2_fetch_array($stmt)) { var_dump($row); } print " Fetching second result set "; $res = db2_next_result($stmt); if ($res) { while ($row = db2_fetch_array($res)) { var_dump($row); } } print " Fetching third result set "; $res2 = db2_next_result($stmt); if ($res2) { while ($row = db2_fetch_array($res2)) { var_dump($row); } } db2_close($conn); } ?> The above example will output: Fetching first result set array(2) { [0]=> string(16) "Bubbles " [1]=> int(3) } array(2) { [0]=> string(16) "Gizmo " [1]=> int(4) } Fetching second result set array(4) { [0]=> string(16) "Sweater " [1]=> int(6) [2]=> string(5) "llama" [3]=> string(6) "150.00" } array(4) { [0]=> string(16) "Smarty " [1]=> int(2) [2]=> string(5) "horse" [3]=> string(6) "350.00" } Fetching third result set array(1) { [0]=> string(16) "Bubbles " } array(1) { [0]=> string(16) "Gizmo " } PHP Documentation Group DB2_NEXT_RESULT(3)
