MySQL Trigger Replace Accented/Unwanted Variables using an Array of Values - mysql

I am trying to create a MySQL trigger to change a string into a proper filename. I would like to replace accented/strange variables with the equivalent counterparts (Québec -> Quebec)
I have an array (I found) with all the characters with the equivalent letter that I would like to replace with:

Is there a way to quickly and efficiently do this replace in my MySQL Trigger?
SET #STRING = "Québec";
FOR EACH ITEM IN ARRAY AS KEY/VALUE
SET #STRING=REPLACE(#STRING,KEY,VALUE);
END;
Or is there a better way to do this? I've tried to change my Encoding/Collation for my column without success.

You can't use arrays directly. But you can work with strings. Change array into string delimited by "," for each key/value pair and further delimited by ":". Then run through string in a while loop.
CREATE FUNCTION `sanitize_string`(STRING varchar(255)) RETURNS varchar(255)
begin
/* set as array as string delimited by a "," for each key/value pair and delimited again by a ":" for each key/value */
/* key is the unwanted character, value is the wanted character */

mySql JSON string field returns encoded

First week having to deal with a MYSQL database and JSON field types and I cannot seem to figure out why values are encoded automatically and then returned in encoded format.
Given the following SQL
-- create a multiline string with a tab example
SET #str ="Line One
Line 2 Tabbed out
Line 3";
-- encode it
SET #j = JSON_OBJECT("str", #str);
-- extract the value by name
SET #strOut = JSON_EXTRACT(#J, "$.str");
-- show the object and attribute value.
SELECT #j, #strOut;
You end up with what appears to be a full formed JSON object with a single attribute encoded.
#j = {"str": "Line One\n\tLine 2\tTabbed out\n\tLine 3"}
but using JSON_EXTRACT to get the attribute value I get the encoded version including outer quotes.
#strOut = "Line One\n\tLine 2\tTabbed out\n\tLine 3"
I would expect to get my original string with the \n \t all unescaped to the original values and no outer quotes. as such
Line One
Line 2 Tabbed out
Line 3
I can't seem to find any JSON_DECODE or JSON_UNESCAPE or similar functions.
I did find a JSON_ESCAPE() function but that appears to be used to manually build a JSON object structure in a string.
What am I missing to extract the values to the original format?
I like to use handy operator ->> for this.
It was introduced in MySQL 5.7.13, and basically combines JSON_EXTRACT() and JSON_UNQUOTE():
SET #strOut = #J ->> '$.str';
You are looking for the JSON_UNQUOTE function
SET #strOut = JSON_UNQUOTE( JSON_EXTRACT(#J, "$.str") );
The result of JSON_EXTRACT() is intentionally a JSON document, not a string.
A JSON document may be:
An object enclosed in { }
An array enclosed in [ ]
A scalar string value enclosed in " "
A scalar number or boolean value
A null — but this is not an SQL NULL, it's a JSON null. This leads to confusing cases because you can extract a JSON field whose JSON value is null, and yet in an SQL expression, this fails IS NULL tests, and it also fails to be equal to an SQL string 'null'. Because it's a JSON type, not a scalar type.

Removing attributes from oracle json object

Use case:
Application requires a subset of attributes, based on business rules
Example:
Some students do not require to enter in home address
Database : Oracle
Proposed implementation:
Build json object containing all possible attribute named pairs, then selectively remove specific named pairs
Issue:
Hoped to use native oracle function to remove the specified named pair.
e.g json_object.remove_attribute('home_address');
However Oracle do not appear to provide any such method.
Workaround : Convert json_object to VARCHAR2 string, and then use combination of INSTR and REPLACE to remove named pair.
Illustrative code:
DECLARE
CURSOR cur_student_json (p_s_ref IN VARCHAR2) IS
SELECT JSON_OBJECT(
,'s_surname' value s.s_surname
,'s_forename_1' value s.s_forename_1
,'s_home_address_1' value s.s_home_address_1
RETURNING VARCHAR2 ) student_json
FROM students s
WHERE s.s_ref = p_s_ref;
BEGIN
FOR x IN cur_student_json (p_s_ref) LOOP
vs_student_json:=x.student_json;
EXIT;
END LOOP;
-- Determine student type
vs_student_type:=get_student_type(p_s_ref);
-- Collect list of elements not required, based on student type
FOR x IN cur_json_inorout(vs_student_type) LOOP
-- Remove element from the json
vs_student_json:=json_remove(vs_student_json,x.attribute);
END LOOP;
END;
/
Question:
There must be an elegant method to achieve requirement
Classify under RTFM. Needs Oracle 12.2
DECLARE
-- Declare an object of type JSON_OBJECT_T
l_obj JSON_OBJECT_T;
-- Declare cursor to build json object
CURSOR cur_student_json (p_s_ref IN VARCHAR2) IS
SELECT JSON_OBJECT(
,'s_surname' value s.s_surname
,'s_forename_1' value s.s_forename_1
,'s_home_address_1' value s.s_home_address_1
) student_json
FROM students s
WHERE s.s_ref = p_s_ref;
BEGIN
-- Initialise object
l_obj := JSON_OBJECT_T();
-- Populate the object
FOR x IN cur_student_json (p_s_ref) LOOP
l_obj:=JSON_OBJECT_T.parse(x.student_json);
EXIT;
END LOOP;
-- Determine student type
vs_student_type:=get_student_type(p_s_ref);
-- Collect list of elements not required, based on student type
FOR x IN cur_json_inorout(vs_student_type) LOOP
-- Remove element from the json
l_obj.remove(x.attribute);
END LOOP;
-- Display modified object
dbms_output.put_line(l_obj.stringify);

How to write data to CSV file in ABL coding

I populated a temp from a query, and the temp table looks like,
ttcomp.inum
ttcomp.iname
ttcomp.iadd
There are 5000 records in this temp table and now i wanted to write in a CSV file. I think it could be done with output stream but i don't know how to implement this. Please someone help me in getting this.
Export does the trick:
/* Define a stream */
DEFINE STREAM str.
/* Define the temp-table. I did some guessing according datatypes... */
DEFINE TEMP-TABLE ttcomp
FIELD inum AS INTEGER
FIELD iname AS CHARACTER
FIELD iadd AS INTEGER.
/* Fake logic that populates your temp-table is here */
DEFINE VARIABLE i AS INTEGER NO-UNDO.
DO i = 1 TO 5000:
CREATE ttComp.
ASSIGN
ttComp.inum = i
ttComp.iname = "ABC123"
ttComp.iadd = 3.
END.
/* Fake logic done... */
/* Output the temp-table */
OUTPUT STREAM str TO VALUE("c:\temp\file.csv").
FOR EACH ttComp NO-LOCK:
/* Delimiter can be set to anything you like, comma, semi-colon etc */
EXPORT STREAM str DELIMITER "," ttComp.
END.
OUTPUT STREAM str CLOSE.
/* Done */
Here is an alternative without stream.
/* Using the temp-table. of Jensd*/
DEFINE TEMP-TABLE ttcomp
FIELD inum AS INTEGER
FIELD iname AS CHARACTER
FIELD iadd AS INTEGER.
OUTPUT TO somefile.csv APPEND.
FOR EACH ttcomp:
DISPLAY
ttcomp.inum + ",":U
ttcomp.iname + ",":U
ttcomp..iadd SKIP.
END.
OUTPUT CLOSE.
There is alternative way also. EXPORT is good in case format doesn't matter because EXPORT ignores format. For example you don't want format for date to be mm/dd/yy. In this case it is better to use PUT STREAM and specify format explicitly.
FOR EACH ttComp NO-LOCK:
PUT STREAM str UNFORMATTED SUBSTITUTE("&1;&2;&3 \n", ttComp.inum, ttcomp.iname, ttcomp.iadd).
END.

Extract first character of each word in MySQL using a RegEx

In my MySQL database I have a column of strings in UTF-8 format for which I want to extract the first character using a RegEx, for example.
Assuming a RegEx which ONLY extracts the following characters:
ਹਮਜਰਣਚਕਨਖਲਨ
And given the following string:
ਹੁਕਮਿ ਰਜਾਈ ਚਲਣਾ ਨਾਨਕ ਲਿਖਿਆ ਨਾਲਿ ॥੧॥
The only characters extracted would be:
ਹਰਚਨਲਨ
I know the following steps would be required to solve this problem:
Break the string into individual words (substrings) by using space as the delimiter
For each word extract the first letter (substring of a substring) if it matches what is in the regex of valid characters
I have looked at all the similar questions/answers on SO and none have been able to solve my problem thus far.
I realy don't know MySql Regex Syntax and restrictions(never used), but you can add leading space before string, and match with something simple like this: " ([ਮਜਰਣਚਕਨਖਲਨ]{1})"
So, if you concatenate matched groups you will have this string "ਰਚਨਲਨ"(only "ਹ" not matched, because it's not exists in sample")
in C# it may look like this(working sample):
namespace TestRegex
{
using System.Linq;
using System.Text.RegularExpressions;
using System.Windows.Forms;
class Program
{
static void Main(string[] args)
{
// leading space(to match first word too)
// + sample string
var sample = " ";
sample += "ਹੁਕਮਿ ਰਜਾਈ ਚਲਣਾ ਨਾਨਕ ਲਿਖਿਆ ਨਾਲਿ ॥੧॥";
// Regex pattern that will math space, and
// if next character in set - add it to "match group 1"
var pattern = " ([ਮਜਰਣਚਕਨਖਲਨ]{1})";
// select every "match group 1" from matches as array
var result = from Match m in Regex.Matches(sample, pattern)
select m.Groups[1];
// concatenate array content into one string and
// show it in message box to user, for example..
MessageBox.Show(string.Concat(result));
}
}
}
in most non-query languages it will be look almost same. For example in php you need to do preg_match_all, and in foreach loop add "$match[i][1]"(every "match group 1") from every match to end of one single string.
well.. pretty simple. but not for mysql...
I finally achieved this with the help of a programmer friend of mine. I directly pasted the following piece of code into the SQL section of my database in PhpMyAdmin:
delimiter $$
drop function if exists `initials`$$
CREATE FUNCTION `initials`(str text, expr text) RETURNS text CHARSET utf8
begin
declare result text default '';
declare buffer text default '';
declare i int default 1;
if(str is null) then
return null;
end if;
set buffer = trim(str);
while i <= length(buffer) do
if substr(buffer, i, 1) regexp expr then
set result = concat( result, substr( buffer, i, 1 ));
set i = i + 1;
while i <= length( buffer ) and substr(buffer, i, 1) regexp expr do
set i = i + 1;
end while;
while i <= length( buffer ) and substr(buffer, i, 1) not regexp expr do
set i = i + 1;
end while;
else
set i = i + 1;
end if;
end while;
return result;
end$$
drop function if exists `acronym`$$
CREATE FUNCTION `acronym`(str text) RETURNS text CHARSET utf8
begin
declare result text default '';
set result = initials( str, '[ੴਓੳਅੲਸਹਕਖਗਘਙਚਛਜਝਞਟਠਡਢਣਤਥਦਧਨਪਫਬਭਮਯਰਲਵੜਸ਼ਖ਼ਗ਼ਜ਼ਫ਼ਲ਼]' );
return result;
end$$
delimiter ;
UPDATE scriptures SET search = acronym(scripture)
Just to explain the last line:
scriptures is the table I want to update
search is a new empty column I created inside the table to store the result
scripture is an existing column inside the scriptures table with all the strings I want to extract from
acronym is the function previously declared which is looking to match the first letter of each word with a character from the RegEx [ੴਓੳਅੲਸਹਕਖਗਘਙਚਛਜਝਞਟਠਡਢਣਤਥਦਧਨਪਫਬਭਮਯਰਲਵੜਸ਼ਖ਼ਗ਼ਜ਼ਫ਼ਲ਼]
So this final line of the code will go through each row of the column scripture, apply the function acronym to it and store the result in the new search column.
Perfect! Exactly what I was looking for :)

Incrementing numerical value and changing string in SQL

I have a database that has stored values in a complicated, serialized array where one component is a string and another is the length of the characters of the string, in this format:
s:8:"test.com"
Where "s" holds the character length of the string in the quotations.
I would like to change the string from "test.com" to "testt.com", and I'm using the following statement in SQL:
UPDATE table SET row=(REPLACE (row, 'test.com','testt.com'))
However, this breaks the script in question, because it doesn't update the character length in the "s" preceding the string where "test.com" is stored.
I was wondering if there is a query I can use that would replace the string, and then also increment the value of this "s" preceding to where the replacement occurs, something like this:
UPDATE table SET row=(REPLACE (row, 's:' number 'test.com','s:' number+1 'testt.com'))
Does anyone know if this kind of query is even possible?
UPDATE table set row = concat('s:',length('testt.com'),':"testt.com"');
If you need to change exact string, then use exact query -
UPDATE table SET row = 's:9:"testt.com"' WHERE row = 's:8:"test.com"';
The string is a "serialized string".
If there are multiple strings to be replaced, it might be easier to create a script to handle this.
In PHP, it goes something like this:
$searchfor = serialize('test.com');
$replaceby = serialize('testt.com');
// strip last semicolon from serialized string
$searchfor = trim($searchfor,';');
$replaceby = trim($replaceby,';');
$query = "UPDATE table SET field = '$replaceby' WHERE field = '$searchfor';";
This way, you can create an exact query string with what you need.
Do fill in the proper code for db connection if necessary.
