create-table

I am trying to create a table in MySQL with the query CREATE TABLE ofRosterGroups ( rosterID BIGINT NOT NULL, rank TINYINT NOT NULL, groupName VARCHAR(255) NOT NULL, PRIMARY KEY (rosterID, rank), INDEX ofRosterGroup_rosterid_idx (rosterID) ); but seems like it is throwing error everytime I made updates too. I don't know what is going wrong with it. Error coming up is You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'rank TINYINT NOT NULL, groupName VARCHAR at line 3 MySQL 8.0.2 added support for the window

In continuation to a previous case , in which a dynamic SELECT query that uses refcursor was created and then was executed - I would like to ask the following: The desired output that we got from the indicated procedure was output into the DataOutput. I would like to find a way to store the data into a new table in the db. Instead of the straight forward command: CREATE TABLE mydaughtertable AS SELECT enrich_d_dkj_p_k27ac,enrich_lr_dkj_p_k27ac,enrich_r_dkj_p_k27ac FROM dkj_p_k27ac The idea is to run something like: CREATE TABLE mydaughtertable AS myresult('dkj_p_k27ac','enri') But this

I want to create a table in MySQL by running following SQL, CREATE TABLE IF NOT EXISTS `shrewd_db`.`alert_disable_register` ( `id_alert_disable_register` MEDIUMINT NOT NULL AUTO_INCREMENT, `id_label` MEDIUMINT UNSIGNED NULL, `id_indicator` MEDIUMINT UNSIGNED NULL, `id_user` MEDIUMINT UNSIGNED NULL, `active` TINYINT(1) NULL DEFAULT 1, `id_alert_disable_rule` MEDIUMINT NULL, `id_escalation_plan` INT NULL, PRIMARY KEY (`id_alert_disable_register`), INDEX `id_escalation_plan_alert_rule_idx` (`id_alert_disable_rule` ASC), INDEX `id_label_idx` (`id_label` ASC), INDEX `id_indicator_idx` (`id

Which is more efficient/better practice/less costly in MySQL (with PHP)? SELECT ing two separate statements, UNION ing them into one, or something else I found online about CREATE ing a temporary table as the MySQL equivalent of SELECT INTO ? Or anything else you can think of? The result will be used in a PHP script. Queries: The first SELECT (let's call it Query A) will always yield 10 rows, 4 columns no matter what. The second SELECT (Query B) will always yield 1 row, 4 columns no matter what. Scenarios: If I SELECT the two statements, I will iterate Query B only if Query A[0]->Col1 > 0 :

This is probably a trivial question, but I'm still a little clumsy when it comes to foreign key constraints so I wanted to make sure. Let's say I have a table countries with the fields country_id (PK) and name , and a table cities with the fields city_id (PK), name and country_id (FK). The foreign key cities.country_id has the constraint ON DELETE SET NULL . As I understand it, this means that if a record from countries is deleted, any records in cities that reference that deleted record's country_id will have its country_id field set to NULL. What if, however, cities.country_id has the

SQL query: CREATE TABLE bonus( bonusid INT( 10 ) DEFAULT '0' NOT NULL AUTO_INCREMENT , empid INT( 10 ) DEFAULT '0' NOT NULL , datebonus DATE DEFAULT '0000-00-00' NOT NULL , bonuspayment VARCHAR( 200 ) NOT NULL , note TEXT NOT NULL , PRIMARY KEY ( bonusid ) ); MySQL said: Documentation 1067 - Invalid default value for 'bonusid' You don't have to give default value for a primary key with auto increment value. Since you have defined bonusid as a primary key and has defined auto increment.So this will automatically create a new value for bonusid whenever a new record is inserted.So try like this

I'm trying to setup temporary tables for unit-testing purposes. So far I managed to create a temporary table which copies the structure of an existing table: CREATE TEMP TABLE t_mytable (LIKE mytable INCLUDING DEFAULTS); But this lacks the data from the original table. I can copy the data into the temporary table by using a CREATE TABLE AS statement instead: CREATE TEMP TABLE t_mytable AS SELECT * FROM mytable; But then the structure of t_mytable will not be identical, e.g. column sizes and default values are different. Is there a single statement which copies everything? Another problem with
