F_STR2EXCEL
- function from adhoc
- Compatible with UTF-8
- Input VARCHAR(32760) String
- Output VARCHAR(32760) String changed for Excel
To convert multiline texts and texts with converted commas to Excel, it is required to transform the string. This function will do the following: - appends a double inverted comma at the beginning and the end of the string - doubles all inverted commas - deletes all CHR(13) in the string - limits the input string to 8190 characters (Limitation in FB UTF8)
Note: Actually it doesn’t make any sense to export a very large text from the database to excel cell, this function may be practicable in combinaton with F_LEFT or F_RIGHT.
Example
SELECT '"1.Line "John" and' || F_CRLF() || '2.Line"' AS ISCORRECT, F_STR2EXCEL('1.Line "John" and' || F_CRLF() || '2.Line') FROM RDB$DATABASE;
Expected results:
=========================== =============================================== "1.Line "John" and 2.Line" "1.Line ""John"" and 2.Line"
Example
SELECT NULL AS ISCORRECT, F_STR2EXCEL(NULL) FROM RDB$DATABASE;
Expected results:
ISCORRECT F_STR2EXCEL ========= =============================================================================== <null> <null>
