Filtering and Grouping: A Comparison of SQL, Linux Scripting, and Ruby
Learn some of the transferable concepts common to Oracle SQL, Linux commands, and scripting to address problems that involve data sets that need to be grouped, sorted, and filtered.
I need following code in linux bash:
Step 1:
run a command and create file1
run a command and create file2
compare file1 and 2
if any difference go to step 1 (keep trying 4 times, if no success, abort program)

Hi,
I have an array of strings. Each string has 4 comma separated values. I am binding this array to a SQL where I am required to do an INSERT after grouping.

OCI_PARSE(3)OCI_PARSE(3)oci_parse - Prepares an Oracle statement for executionSYNOPSIS
resource oci_parse (resource $connection, string $sql_text)
DESCRIPTION
Prepares $sql_text using $connection and returns the statement identifier, which can be used with oci_bind_by_name(3), oci_execute(3) and
other functions.
Statement identifiers can be freed with oci_free_statement(3) or by setting the variable to NULL.
PARAMETERS
o $connection
- An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3).
o $sql_text
- The SQL or PL/SQL statement. SQL statements should not end with a semi-colon (";"). PL/SQL statements should end with a semi-
colon (";").
RETURN VALUES
Returns a statement handle on success, or FALSE on error.
EXAMPLES
Example #1
oci_parse(3) example for SQL statements
<?php
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
// Parse the statement. Note there is no final semi-colon in the SQL statement
$stid = oci_parse($conn, 'SELECT * FROM employees');
oci_execute($stid);
echo "<table border='1'>
";
while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {
echo "<tr>
";
foreach ($row as $item) {
echo " <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : " ") . "</td>
";
}
echo "</tr>
";
}
echo "</table>
";
?>
Example #2
oci_parse(3) example for PL/SQL statements
<?php
/*
Before running the PHP program, create a stored procedure in
SQL*Plus or SQL Developer:
CREATE OR REPLACE PROCEDURE myproc(p1 IN NUMBER, p2 OUT NUMBER) AS
BEGIN
p2 := p1 * 2;
END;
*/
$conn = oci_connect('hr', 'welcome', 'localhost/XE');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
$p1 = 8;
// When parsing PL/SQL programs, there should be a final semi-colon in the string
$stid = oci_parse($conn, 'begin myproc(:p1, :p2); end;');
oci_bind_by_name($stid, ':p1', $p1);
oci_bind_by_name($stid, ':p2', $p2, 40);
oci_execute($stid);
print "$p2
"; // prints 16
oci_free_statement($stid);
oci_close($conn);
?>
NOTES
Note
This function does not validate $sql_text. The only way to find out if $sql_text is a valid SQL or PL/SQL statement is to execute
it.
