Top Forums Shell Programming and Scripting awk search for Quoted strings (') Post 302125994 by aigles on Monday 9th of July 2007 01:40:03 PM

Code:
awk -F "'" '{ for (f=1; f<=(NF-1)/2; f++) print $(f*2) }' input_text

-F "'"
Define the quote ' as the Field Separator for Input Records.
for (f=1; f<=(NF-1)/2; f++)
Loop same as in C.
As the field separator is ', the quoted strings are in fields 2, 4, 6, ...
For example, input=first 'quotation 1' and second 'quotation 2', no more...
Field1=first f=1
Field2=quotation 1 f=1, field f*2=2
Field3= and second f=2 =(NF-1)/2
Field4=quotation 2' f=2, field f*2=4
Field5=, no more...
If the number of fields (NF) is even, there is a missing quote.
print $(f*2)
Print the quoted string.

cubrid_real_escape_string - Escape special characters in a string for use in an SQL statement

SYNOPSIS
string cubrid_real_escape_string (string $unescaped_string, [resource $conn_identifier]) DESCRIPTION
This function returns the escaped string version of the given string. It will escape the following characters: '. In general, single quo- tations are used to enclose character string. Double quotations may be used as well depending on the value of ansi_quotes, which is a parameter related to SQL statement. If the ansi_quotes value is set to no, character string enclosed by double quotations is handled as character string, not as an identifier. The default value is yes. If you want to include a single quote as part of a character string, enter two single quotes in a row. PARAMETERS
o $unescaped_string -The string that is to be escaped. o $conn_identifier - The CUBRID connection. If the connection identifier is not specified, the last connection opened by cubrid_connect(3) is assumed. RETURN VALUES
Escaped string version of the given string, on success. FALSE on failure. EXAMPLES
