Question

I have a CSV whihc contains 3 fields as below:

value1, value2, value 3

Note: there is a space between “value” and “3” in the 3rd field.

I am uploading this data row by row to Oracle DB using perl DBD::Oracle and DBI.

here is the query that I am using to upload:

$dbh->do ("INSERT INTO $table VALUES ($col1_value, $col2_value, $col3_value)");

however, it is faling to upload and complaining like below:

DBD::Oracle::db do failed: ORA-00917: missing comma (DBD ERROR: error possibly near <*> indicator at char 103 in 'INSERT INTO TABLE_NAME VALUES (value1, value2, value <*>3 )')

So it is failing on hte 3rd value whihc contains a space.

could you guide me on how to upload the string with “Space” in it to Oracle.

BTW, I am not oracle guy so please point me if anything that I am doing is wrong.

Thnaks.

Answer 1

For many reasons (security, efficiency, correctness) you want to be using placeholders to put values into SQL.

my $rows = $dbh->do (
    "INSERT INTO $table VALUES (?, ?, ?)",
    undef,
    $col1_value, $col2_value, $col3_value
);

This avoids needing to do any escaping both for syntactical and security purposes.
