This is my Stored procedure . I have problem to assign value to Declared variable . When I Execute it, Insert and Update Command work fine but VALUE of Declared Variable remain 0; But I have some value in Database. How can i Do this Corectly.
BEGIN
DECLARE PaidFee INT DEFAULT 0;
DECLARE DueFee INT DEFAULT 0;
DECLARE CourseFee INT DEFAULT 0;
INSERT INTO `creditdirectory`(`TypeID`, `PersonName`, `CreditBy`, `PersonID`, `ModeOfPayment`,`Details`,`Amount`,`CompanyID`)
VALUES(1,PersonName,CreditBy, AddmissionID, ModeOfPayment, 'Installment', PaidAmount,
CompanyID);
SELECT `CourseFee`,`PaidFee`,`DueFee` INTO CourseFee,PaidFee,DueFee FROM `studentcoursedetails` WHERE `ID`= CourseID;
SET PaidFee = PaidFee + PaidAmount;
SET DueFee = CourseFee - PaidFee;
IF (NextDueDate !='') THEN
UPDATE `studentcoursedetails` SET `PaidFee` = PaidFee, `DueFee` = DueFee, `DueDate` = NextDueDate WHERE `ID`= CourseID;
ELSE
UPDATE `studentcoursedetails` SET `PaidFee` = PaidFee, `DueFee` = DueFee, `DueDate` = NULL WHERE `ID` = CourseID;
END IF;
END
Don't use variables with same name of columns, the query will take preference on table column names.
A good idea is use variables with prefix:
BEGIN
DECLARE p_PaidFee INT DEFAULT 0;
DECLARE p_DueFee INT DEFAULT 0;
DECLARE p_CourseFee INT DEFAULT 0;
INSERT INTO `creditdirectory`(`TypeID`, `PersonName`, `CreditBy`, `PersonID`, `ModeOfPayment`,`Details`,`Amount`,`CompanyID`)
VALUES(1,PersonName,CreditBy, AddmissionID, ModeOfPayment, 'Installment', PaidAmount,
CompanyID);
SELECT `CourseFee`,`PaidFee`,`DueFee` INTO p_CourseFee,p_PaidFee,p_DueFee FROM `studentcoursedetails` WHERE `ID`= CourseID;
SET p_PaidFee = p_PaidFee + PaidAmount;
SET p_DueFee = p_CourseFee - p_PaidFee;
IF (NextDueDate !='') THEN
UPDATE `studentcoursedetails` SET `PaidFee` = p_PaidFee, `DueFee` = p_DueFee, `DueDate` = NextDueDate WHERE `ID`= CourseID;
ELSE
UPDATE `studentcoursedetails` SET `PaidFee` = p_PaidFee, `DueFee` = p_DueFee, `DueDate` = NULL WHERE `ID` = CourseID;
END IF;
END

I am just learning to code SQL. Can someone help me with an update statement, I have done the insert but am stuck with an update. My table prime_test has two columns number and is_prime
Here is the question:
Write one or more update statements that sets the 'is_prime' column for each associated integer. For a prime, the column should read 'prime'. For non-primes, the column should read 'composite'.
My code
CREATE TABLE `sql_inventory`.`prime_test` (
`number` INT NOT NULL,
`is_prime` VARCHAR(50) NULL,
PRIMARY KEY (`number`));
INSERT INTO `prime`.`prime_test`
(`number`)
VALUES
(rand()*(100-2+1)+2);
Function to find the prime numbers:
CREATE FUNCTION isPrime(#num int)
RETURNS VARCHAR(50)
BEGIN
DECLARE #prime_or_notPrime INT
DECLARE #counter INT
DECLARE #retVal VARCHAR(50)
SET #retVal = 'composite'
SET #prime_or_notPrime = 1
SET #counter = 2
WHILE (#counter <= #number/2 )
BEGIN
IF (( #number % #counter) = 0 )
BEGIN
set #prime_or_notPrime = 0
BREAK
END
IF (#prime_or_notPrime = 1 )
BEGIN
SET #retVal = 'prime'
END
SET #counter = #counter + 1
END
return #retVal
END
update prime_test
set is_prime = dbo.isPrime(select number From 'prime'.'prime_test')

have an exception command in the cursor some thing like below :
Exception
When NO_DATA_FOUND then
continue
end;
it will help to avoid no data found error.
My question is kind of hard to explain in title so I'll show the data and goal.
There is a MySQL table with following structure:
CREATE TABLE customerProjectData(
idCustomer INT NOT NULL,
idProject INT DEFAULT NULL,
comePersons SMALLINT DEFAULT NULL,
comePairs SMALLINT DEFAULT NULL,
comment VARCHAR(255) DEFAULT NULL,
idCity INT DEFAULT NULL,
idStreet INT DEFAULT NULL,
name VARCHAR(64) DEFAULT NULL,
surname VARCHAR(64) DEFAULT NULL,
homeNum VARCHAR(10) DEFAULT NULL,
postCode CHAR(6) DEFAULT NULL,
postCity VARCHAR(64) DEFAULT NULL,
cellPhone VARCHAR(12) DEFAULT NULL
)
The thing is, there shold be also PRIMARY KEY(idCustomer, idProject) defined and it's not. As a result There are kind of duplicates (with the same primary key) but with different data.
I could run ALTER IGNORE TABLE but data loss would probably be unacceptable and unpredicatable. Finally we decided to try to fill null fields with values from duplicates if they contain data and after that run the ALTER IGNORE TABLE. Much less data will be lost that way and it's acceptable in this case (it's better than leaving it as it is now in longer time perspective).
The question is how to fill those fields from each duplicate.
Here is a rough try.
First try to find out the no. of rows which have the same key.
<?php
// $link is the database identifier
$sql = 'SELECT COUNT(*) AS num, * FROM `customerProjectData` GROUP BY `idCustomer`, `idProject` HAVING COUNT(*) > 1 ORDER BY COUNT(*) ASC;';
$run = mysql_query( $sql, $link );
$rows = array();
if( $run && mysql_num_rows( $run ) ) {
while( ( $fetch = mysql_fetch_assoc( $run ) ) !== false ) {
$rows[] = $fetch;
}
}
?>
Now $rows contains a list of all rows which have the same key and a count of how many times this key has been repeated in the table.
You can write a function which then iterates count times and see which rows has the complete data and use that to populates other records with this record's data.
A bit of trial and error.
I used #web-nomad suggestion and did something similar, but in sql procedure:

My procedure inserts the values: A1G1R1S1B1 and A1G1R1S1B2. And the inner loop breaks.
but the correct insertion should be: A1G1R1S1B1 and A1G1R1S1B2 and A1G1R1S2B1 and A1G1R1S2B2.
The insert is obviously incomplete. How should I place my insert statement or change the looping as to cater the needs?
Please help. Thanks
Why don't use simple SQL to do this task ?
Look at the following example
We need a table with a seqence of numbers from 1 to X - where X is a maximum number whenever we need.
CREATE TABLE numbers(
x int primary key auto_increment
);
INSERT INTO numbers
SELECT null FROM information_schema.columns;
SELECT max( x ) FROM numbers;
| MAX( X ) |
|----------|
| 558 |
And now the below simple select will generate all required records for us
(see this demo: http://sqlfiddle.com/#!2/1e5c4b/7
- you will need to scroll to the bottom of the page to see a result of the query):
SET #strA = 'A';
SET #strB = 'G';
SET #strC = 'R';
SET #strD = 'S';
SET #strE = 'B';
SET #strF= '';
SET #a = 2;
SET #b = 2;
SET #c = 2;
SET #d = 2;
SET #e = 2;
SELECT *,
CONCAT(strA, strB, strC, strD, strE) strF,
1 As warehouse_id
FROM (
SELECT Concat(#strA,x) strA
FROM numbers
WHERE x <= #a
) A
CROSS JOIN
(
SELECT Concat(#strB,x) strB
FROM numbers
WHERE x <= #b
) B
CROSS JOIN
(
SELECT Concat(#strC,x) strC
FROM numbers
WHERE x <= #c
) C
CROSS JOIN
(
SELECT Concat(#strD,x) strD
FROM numbers
WHERE x <= #d
) D
CROSS JOIN
(
SELECT Concat(#strE,x) strE
FROM numbers
WHERE x <= #e
) E
And now just place an INSERT statement at the top of the above query:
INSERT INTO BIN (`aisle`, `room`, `rack`, `shelf`, `bin`, `barcode`, `warehouse_id`)
SELECT *,
CONCAT(strA, strB, strC, strD, strE) strF,
1 As warehouse_id
FROM (
SELECT Concat(#strA,x) strA
FROM numbers
WHERE x <= #a
) A
CROSS JOIN
(
SELECT Co .....
