How to create a sequence on selected values in MySQL?

问题 I'm trying to create a query which will select a team from a declared variable and then make the remaining teams "anonymous" by giving them generic brands and sequential IDs. For example, if my dataset has 3 different team names (ABC, DEF, and GHI), but I would only like the true value of the 1 chosen team (ABC) displayed. Here is the skeleton of the query I'm working with: SET @teamid = 123; SELECT CASE WHEN ID = @teamid THEN NAME ELSE 'Team' + ' - ' + SEQ END AS 'Team Name', SUM(TOTAL) AS

问题 I am trying to work with postgresql 'nextval' in PHP. How can I fill in the parenthesis in the third line in order to replace TXN_ID with the value of nextval('schemadb.audit_txn_seq')? $DB->query("SELECT nextval('schemadb.audit_txn_seq')"); $DB->query('SET CONSTRAINTS ALL DEFERRED'); $DB->query('SELECT schemadb.undo_transaction(TXN_ID)'); Thanks! 回答1: You did not tell us what is $DB variable. I guess you are using PDO. The question "Is there anyway to store the result of query into php

PostgreSQL next value of the sequences?

由 谁说我不能喝 提交于 2019-12-17 10:56:24
问题 I am using PostgreSQL for my Codeigniter website. I am using grocery crud for add, edit and delete operations. While doing an edit or add, I want to rename an uploaded file dynamically based on the id of the content. I am able to do this using grocery crud's callback_after_upload function. I want a next id of the content while adding a new content. I tried to use nextval() function, but sequence gets incremented with it. How can get the last value of the sequence without using nextval()

postgresql nextval generating existing values

由 风格不统一 提交于 2019-12-07 02:26:43
问题 I had to migrate from a mySql based ruby on rails app to using postgresql. No problems but one so far, and I don't know how to solve it. The migration of data brought ids along with it, and postgresql is now having problems with existing ids: it's not clear to me where it gets the value that it uses to determine the base for nextval: it certainly isn't the highest value in the column, although you might think that would be a good idea. In any case, it's now colliding with existing id values.

问题 I have a class mapped as an Entity to persist it in a database. I have an id field as the primary key so every time the object is persisted the value of the id is retrieved from the sequence "myClass_pk_seq", a code like the following one. @Entity @Table(name="myObjects") public class MyClass { @Id @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="sequence") @SequenceGenerator(name="sequence", sequenceName="myClass_pk_seq", allocationSize=1) @Column(name="myClassId") private

Select multiple ids from a PostgreSQL sequence

由 我与影子孤独终老i 提交于 2019-11-30 11:07:28
Is there a concise way to select the nextval for a PostgreSQL sequence multiple times in 1 query? This would be the only value being returned. For example, I would like to do something really short and sweet like: SELECT NEXTVAL('mytable_seq', 3) AS id; And get: id ----- 118 119 120 (3 rows) select nextval('mytable_seq') from generate_series(1,3); generate_series is a function which returns many rows with sequential numbers, configured by it's arguments. In above example, we don't care about the value in each row, we just use generate_series as row generator. And for each row we can call
