REPLACE INTO pv_network_coverage(carrier_group_id,
network_group_id,
physician_count,
facility_count,
pcp_count,
update_time) SELECT *FROM temp_pv_network_coverage;
I use replace into and insert into with duplicate keys.
The physician_count should be 1000 but still 0..
It really makes me surprised.
Remember to select columns instead of select *from

I have archived some old line items for invoices that are no longer current but still need to reference them. I think I need to create a VIEW but not really understanding it. Can someone help so I can run a query to pull the invoice and then the total of all the line items assigned (no matter what table the items are in)?
CREATE TABLE `Invoice` (
`Invoice_ID` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT,
`Invoice_CreatedDateTime` DATETIME DEFAULT NULL,
`Invoice_Status` ENUM('Paid','Sent','Unsent','Hold') DEFAULT NULL,
`LastUpdatedAt` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`ID`),
KEY `LastUpdatedAt` (`LastUpdatedAt`)
) ENGINE=MYISAM DEFAULT CHARSET=latin1
CREATE TABLE `Invoice_LineItem` (
`LineItem_ID` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT,
`LineItem_ChargeType` VARCHAR(64) NOT NULL DEFAULT '',
`LineItem_InvoiceID` INT(11) UNSIGNED DEFAULT NULL,
`LineItem_Amount` DECIMAL(11,4) DEFAULT NULL,
`LastUpdatedAt` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`LineItem_ID`),
KEY `LastUpdatedAt` (`LastUpdatedAt`),
KEY `LineItem_InvoiceID` (`LineItem_InvoiceID`)
) ENGINE=MYISAM AUTO_INCREMENT=1 DEFAULT CHARSET=latin1
CREATE TABLE `Invoice_LineItem_Archived` (
`LineItem_ID` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT,
`LineItem_ChargeType` VARCHAR(64) NOT NULL DEFAULT '',
`LineItem_InvoiceID` INT(11) UNSIGNED DEFAULT NULL,
`LineItem_Amount` DECIMAL(11,4) DEFAULT NULL,
`LastUpdatedAt` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`LineItem_ID`),
KEY `LastUpdatedAt` (`LastUpdatedAt`),
KEY `LineItem_InvoiceID` (`LineItem_InvoiceID`)
) ENGINE=MYISAM AUTO_INCREMENT=1 DEFAULT CHARSET=latin1
Typically I would just run the following query to get the amount due on the invoices
SELECT
Invoice_ID,
Invoice_CreatedDateTime,
Invoice_Status,
(SELECT SUM(LineItem_Amount) AS totAmt FROM Invoice_LineItem WHERE LineItem_InvoiceID=Invoice_ID) AS Invoice_Total
FROM
Invoice
WHERE
Invoice_Status='Sent'
Also how can I select all the line items from both tables in one query?
SELECT
LineItem_ID,
LineItem_ChargeType,
LineItem_Amount
FROM
Invoice_LineItem
WHERE
LineItem_InvoiceID='1234'
You can use the MERGE Storage Engine to create a virtual table that's the union of two real tables:
CREATE TABLE Invoice_LineItem_All
(
`LineItem_ID` INT(11) UNSIGNED NOT NULL AUTO_INCREMENT,
`LineItem_ChargeType` VARCHAR(64) NOT NULL DEFAULT '',
`LineItem_InvoiceID` INT(11) UNSIGNED DEFAULT NULL,
`LineItem_Amount` DECIMAL(11,4) DEFAULT NULL,
`LastUpdatedAt` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
KEY (`LineItem_ID`),
KEY `LastUpdatedAt` (`LastUpdatedAt`),
KEY `LineItem_InvoiceID` (`LineItem_InvoiceID`)
) ENGINE=MERGE UNION=(Invoice_LineItem_Archived, Invoice_LineItem);
You can use UNION :
SELECT a.* FROM a
UNION
SELECT b.* FROM b;
You just need to have the same number and type of column in your different queries.
As far as I remember, you can add test in sub-queries, but I'm not sure you can order on the global result.

I have a table with many many duplicated row, I cannot create a unique value for the blob field, because is too large.
How can I find and delete the duplicate rows where the blob field (answer) is duplicated?
This is the table structure :
CREATE TABLE `answers` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`id_question` int(11) NOT NULL,
`id_user` int(11) NOT NULL,
`answer` blob NOT NULL,
`language` varchar(2) NOT NULL,
`datetime` datetime NOT NULL,
`enabled` int(11) NOT NULL DEFAULT '0',
`deleted` int(11) NOT NULL DEFAULT '0',
`spam` int(11) NOT NULL DEFAULT '0',
`correct` int(11) NOT NULL DEFAULT '0',
`notification_send` int(11) NOT NULL DEFAULT '0',
`correct_notification` int(11) NOT NULL DEFAULT '0',
PRIMARY KEY (`id`),
KEY `id_question` (`id_question`),
KEY `id_user` (`id_user`),
KEY `enabled` (`enabled`)
) ENGINE=InnoDB AUTO_INCREMENT=1488 DEFAULT CHARSET=utf8mb4
probable you can use prefix of the column by substr() or left() and compare. How much size you want to take that depends on your data distribution or prefix uniqueness of the column data.
for uniqueness check you can fire the below query if the
select count(distinct left(answer, 128))/count(*), count(distinct left(answer, 256))/count(*) from answers.
This will provide you selectivity or data distribution in your column. suppose 128 gives you answer as 1 i.e. all unique if you take first 128 bytes then choose that amount of data from each row and work. Hope it helps.
I like to append a table to add column but without using alert table command
e.g.
This is the table which is missing some columns.
CREATE TABLE IF NOT EXISTS `admin` (
`id` int(11) NOT NULL auto_increment,
`username` varchar(20) NOT NULL,
`passwd` varchar(40) NOT NULL,
`isActive` tinyint(1) NOT NULL default '1',
`lastVisit` datetime NOT NULL default '0000-00-00 00:00:00',
`modifyAt` datetime NOT NULL,
`createdAt` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
So if i run this query then it should automatically add missing columns into my tables
CREATE TABLE IF NOT EXISTS `admin` (
`id` int(11) NOT NULL auto_increment,
`username` varchar(20) NOT NULL,
`passwd` varchar(40) NOT NULL,
`name` varchar(100) NOT NULL,
`originalUser` tinyint(1) NOT NULL default '0',
`isActive` tinyint(1) NOT NULL default '1',
`lastVisit` datetime NOT NULL default '0000-00-00 00:00:00',
`modifyAt` datetime NOT NULL,
`createdAt` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
Can this be possible to do without using alert table command ?
I understand your question as you want to add some columns to your table. Please be informed that the term row is usually related to the actual data in your table, not the columns itself. If my assumption is wrong, please clarify your question.
You cannot use CREATE TABLE for altering a table. It is there to create table,
and if it cannot create it, it will in most cases throw an error like you described. Another command exists for that reason: ALTER TABLE.
You might do it something like this.
(1) Create your table with your CREATE TABLE syntax above:
CREATE TABLE IF NOT EXISTS `admin` (
`id` int(11) NOT NULL auto_increment,
`username` varchar(20) NOT NULL,
`passwd` varchar(40) NOT NULL,
`isActive` tinyint(1) NOT NULL default '1',
`lastVisit` datetime NOT NULL default '0000-00-00 00:00:00',
`modifyAt` datetime NOT NULL,
`createdAt` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
(2) Use ALTER TABLE like this to make the modifications I think you want to have in your second statement (two more columns):
ALTER TABLE
ADD COLUMN `name` varchar(100) NOT NULL AFTER `passwd`,
ADD COLUMN `originalUser` tinyint(1) NOT NULL default '0' AFTER `name`;
Not related to your question, but I'd avoid column names like name, because if you don't escape them properly it'll throw you other errors (see reserved words).
I have a table. (Code taken from table generation code, I did not write this)
DROP TABLE IF EXISTS `CatalogueBasket`;
CREATE TABLE `CatalogueBasket` (
`ID` int(11) NOT NULL auto_increment,
`Shopper` char(35) NOT NULL default '',
`ItemLink` int(11) NOT NULL default '0',
`Quantity` int(11) NOT NULL default '0',
`Created` datetime NOT NULL default '0000-00-00 00:00:00',
`ExpectedDelivery1` datetime default NULL,
`ExpectedDelivery2` datetime default NULL,
`Comments` char(255) default NULL,
`Status` int(10) unsigned default NULL,
`QuantityShipped` int(10) unsigned default NULL,
`HarmonyNumber` int(10) unsigned default NULL,
`StartDate` datetime default NULL,
KEY `ID` (`ID`),
KEY `Shopper` (`Shopper`),
KEY `ItemLink` (`ItemLink`),
KEY `Quantity` (`Quantity`),
KEY `Created` (`Created`)
) TYPE=MyISAM;
When trying to insert a new Row at the end of this table I am getting the following message.
Duplicate entry '116604' for key 1
The insert statement is:
INSERT INTO CatalogueBasket (Shopper,ItemLink,Quantity,Created, Status, StartDate)
VALUES ('0.80916300 1338507348',58825,1,'2012-06-01 09:58:23', 0, '0-0-0')
I'm assuming it is talking about the ID column.
If I run the following query I get 116603 as the last key
SELECT * FROM `CatalogueBasket` order by ID desc limit 1
Any insight / help into this is appreciated.
I have two mysql tables and i want to merge the results of these two tables based on the common column rev_id. The merged results should be sorted by the date of two tables.
Please help me.
CREATE TABLE `reply` (
`id` int(3) NOT NULL auto_increment,
`name` varchar(25) NOT NULL default '',
`member_id` varchar(45) NOT NULL,
`rev_id` int(3) NOT NULL default '0',
`description` text,
`post_date` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
`flag` char(2) NOT NULL default 'N',
PRIMARY KEY (`id`),
KEY `member_id` (`member_id`)
) ENGINE=MyISAM;
CREATE TABLE `comment` (
`com_id` int(8) NOT NULL auto_increment,
`rev_id` int(5) NOT NULL default '0',
`member_id` varchar(50) NOT NULL,
`comm_desc` text NOT NULL,
`date_created` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
PRIMARY KEY (`com_id`),
KEY `member_id` (`member_id`)
) ENGINE=MyISAM;
Try this:
SELECT * FROM reply LEFT JOIN comment ON reply.rev_id = comment.rev_id ORDER BY reply.post_date, comment.date_created
