![]() But when I insert a new sql in my app, still get a small seed id. How to check the table primary key current start with value?When I am using this command to check the current seed value of id: select CURRVAL(pg_get_serial_sequence('public.rss_sub_source', 'id')) I am using this command to modify the start with value: ALTER TABLE rss_sub_source Rep_lastest_refresh_time int8 NULL DEFAULT 0,ĭynamic_interval int4 NOT NULL DEFAULT 0,ĬONSTRAINT rss_sub_source_pkey PRIMARY KEY (id),ĬONSTRAINT unique_sub_url UNIQUE (sub_url) Standard_version varchar(32) NOT NULL DEFAULT 'rss20'::character varying,Ĭron varchar NOT NULL DEFAULT '0 */1 * * * *'::character varying, To change a sequence's schema, you must also have CREATE privilege on the new schema. You must own the sequence to use ALTER SEQUENCE. Any parameters not specifically set in the ALTER SEQUENCE command retain their prior settings. Standard_type varchar(32) NOT NULL DEFAULT 'RSS'::character varying, Description ALTER SEQUENCE changes the parameters of an existing sequence generator. Id int8 NOT NULL GENERATED ALWAYS AS IDENTITY,Ĭreated_time int8 NOT NULL DEFAULT date_part('epoch'::text, now()), This is my table create command: - Drop table What should I do to make it work? This command still not work: ALTER TABLE rss_sub_source Then I modify the SQL like that: ALTER TABLE rss_sub_sourceĭid not work shows SQL Error : ERROR: syntax error at or near "(" Position: 74. sql - Does postgres support to set start value at serial definition - Stack Overflow Does postgres support to set start value at serial definition Ask Question Asked 6 years, 1 month ago Modified 6 years, 1 month ago Viewed 5k times 5 Here is a question about changing serial value with alter key word. ![]() The new sequence can be altered and configured as a regular sequence. Shows this column already as a identify column. By assigning a SERIAL type to a column as part of table creation, PostgreSQL creates a sequence using default configuration and adds the NOT NULL constraint to the column. I have tried this way: ALTER TABLE rss_sub_sourceĪLTER id ADD GENERATED ALWAYS AS IDENTITY You can alter a sequence using RESTART WITH to change the current sequence number ALTER SEQUENCE testseq RESTART WITH 300 To get the sequence name if you created it using the serial keyword, use. Now I want to modify the start with value(I forget to define the start with value when I added identify column). How to check the table primary key current start with valueWhen I am using this command to check the current seed value of id: select CURRVAL (pggetserialsequence ('public.rsssubsource', 'id')) shows greater than 1200. infra/main.bicep load the module using module appEnvironment './core/host/container-apps-environment.I have a table rss_sub_source, and the id as a identify column. Output appEnvironmentId string = appEnvironment.id infra/core/host/container-apps-environment.bicep module with the following content param name string SharedKey: logAnalytics.listKeys().primarySharedKeyĪzd templates must use bicep modules. To do that in Bicep, update the environment resource in bicep to resource logAnalytics = -log-analytics'ĬustomerId: This makes your deployment and resources significantly more clear and predictable, at the cost of some verbosity. To achieve the same using a bicep template you must explicitly declare it and link it. The Azure CLI will automatically create a Log Analytics work space for each environment. ![]() ![]() By digoal Background Currently, Alibaba Cloud DTS does not support the migration of sequence values. Initialize a Minimal azd template azd init \ digoal Decem2,219 0 This short article explains the sample code for setting SQL for sequences in PostgreSQL. To deploy the bicep template at any stage use: az deployment group create -g $RESOURCE_GROUP \ĭefine a couple of values to use for azd AZURE_ENV_NAME="azd-postgres-dev" Param pgsqlCliAppName string = 'psql-cloud-cli-app' Param appEnvironmentName string = 'aca-env' Param location string = resourceGroup().location These numbers are known as 'sequences' and have their own designated table. So define the following variables for the CLI RESOURCE_GROUP="postgres-dev"įor Bicep, start by creating a file called postgres-dev.bicep then add some parameters with default values to it targetScope = 'resourceGroup' How to Alter Sequence in PostgreSQL How to Alter Sequence in PostgreSQL If you have a serial ID column (ie auto incrementing ID), they'll start at 1 by default, but sometimes you may want them to start at a different number. You can use pggetserialsequence () to get the name of the sequence: SELECT setval (pggetserialsequence ('thetable', 'id'), coalesce (MAX (id), 1)) from thetable The above works for serial and identity columns the same way. PostgreSQL Serial Type Create a sequence object and assign the next value generated by the sequence as a default value to a column. You still need to use the CLI to deploy the bicep template into a resource group. 1 Answer Sorted by: 13 You can do the same with identity columns - they also use a sequence. ![]()
