I will try to explain how to create a job dynamically in the next tutorial. Job Scheduling coupled with exporting data in CSV format is a powerful feature of PostgreSQL. It is not always feasible to create schedulers in your code, but when it's an option, it can be really helpful. To edit a job in pgAgent you select the job and click on the Properties tab on the dashboard.Ĭlick on the pencil icon in the top left corner, it will open a wizard where you can edit all the details. Once I changed the path, my job was successfully executed (note the first row). In my case it wasn't able to access the directory I was trying to copy the data to. In the output column you can see why the job failed. To debug why a job failed, you can simply click on the name of the step under Steps in the browser tree and click Statistics on the dashboard. s means success and f means failed in the Status column. Here you can view the number of times the job was executed, start and end time, its status and id. To see whether the job was executed (whether it failed or succeeded), you select the job by its name and click on the Statistics tab in the dashboard. Its schedules and steps will be displayed when you extend the job. Once a new job is created, it will be displayed under pgAgent jobs in the browser tree.
If you want to schedule a job dynamically you will have to execute the procedure code displayed here. In the Schedules tab we add the start date time and the end date time for the job to start and end. I will save the changes after adding the code. The code will be:ĬOPY (select * from acc_view) TO E'C:\\test-data\\try.csv' Since I want to export the data from a view, I will call the view and ask it to export the file. Next comes the code section in Steps tab. In the On Error select box, you can pick what should be happen in case an error occurs.I will add my connection details in the same format: host=localhost port=5432 dbname=postgres The syntax should be like in libq connection string. A remote connection allows you to manually add the Connection String.Depending on whether your job is local or remote, you can pick the Connection type.Your job will run only if the step is enabled. The Steps tab has two sections: General and Code. In the top right corner of the box you will see a + sign. Next we click on the Steps tab in the create pgAgent dialog box. Since I want to export the data to a CSV, I will pick the Data Export category. You can select one based on the function of the job. Here you enter the name of the job and select a category.Ĭategory is just for internal categorization purposes – this does not affect how your job runs. The create pgAgent dialog box has four tabs. You will see a menu, and there just click create > pgAgent Job. To create a new job, right click on the pgAgent Jobs button and click on create. PgAgent jobs will be visible to you in the browser tree on the left side of the dashboard.Ībove you can see a close up view of the browser tree. To uninstall them you need to use the Control Panel.
Once Stack Builder is installed you simply run it to install other utilites. It has instructions to install and uninstall utilites. Stack Builder will also display an installation completed wizard.
NOTE: Login to PostgreSQL with the username and password you provided at this stage to view pgAgent jobs.Īfter adding those details, the setup begins: If you enter incorrect details it will throw a connection error.
In the PostgreSQL installation details wizard, provide the username and password that you entered when you installed PostgreSQL. If you do not want to automatically change scripts while upgrading you can check the box.
Here you will pick whether you want to install it in an upgrade mode.
Stack Builder will then open a pgAgent SetUp Wizard.
Next, it will ask you to choose a directory where you want to install pgAgent. Under Adds-ons, tools and utilities, you will find pgAgent. If you have multiple PostgreSQL versions installed you will pick one to use to install pgAgent. When you run Stack Builder it will first open a welcome wizard. Stack Builder runs once PostgreSQL installation is complete. If you have PostgreSQL already installed, you could download the installer and run Stack Builder if you don't have it already. This will download Stack Builder along with the installer. Install PostreSQL from the official website. You can install pgAgent with Stack Builder.
How to Install PostgreSQL and Stack Builder We'll use pgAgent, a job scheduling agent for PostgreSQL. In this article we will see how to schedule a job in PostgreSQL. Scheduling allows you to automate things so you don't have to do them in real time.
