Hi Don,

I tried using :

sed -e 's/^"/^B/' -e 's/"$/^B/' -e 's/",/^B,/g' -e 's/,"/,^B/g' -e 's/"//g' -e 's/^B/"/g'
but i could see that all the double quotes are replaced by
^B
and also eliminating the last double quote in the data file.

Input:

Code:
   221100,37.20,"C","0073/1454","44019120","16395","16395/14103000","Safety   Workwear - "Screwfix","","Screwfix Direct   Ltd","10/10/2014","2520",""

Output:

Code:
   ^B221100^B,37.20,^BC^B,^B0073/1454^B,^B44019120^B,^B16395^B,^B16395/14103000^B,^BSafety   Workwear - Screwfix^B,^B^B,^BScrewfix Direct Ltd^B,^B10/10/2014^B,^B2520^B,^B

Expected Output:

Code:
   221100,37.20,"C","0073/1454","44019120","16395","16395/14103000","Safety   Workwear - Screwfix","","Screwfix Direct   Ltd","10/10/2014","2520",""

If you can see in the output , the last column with null value has been replaced only with a single double quote.

Please help me to resolve this issue.

Regards,
Lavanya.

It returns an escaped identifier string for PostgreSQL server. pg_escape_identifier(3) adds double quotes before and after data. Users should not add double quotes.

A string containing the escaped data. EXAMPLES
Example #1 pg_escape_identifier(3) example <?php // Connect to the database $dbconn = pg_connect('dbname=foo'); // Escape the table name data $escaped = pg_escape_identifier($table_name); // Select rows from $table_name pg_query("SELECT * FROM {$escaped};"); ?> SEE ALSO
