These properties are used to configure tCreateTable running in the Standard Job framework.

The Standard tCreateTable component belongs to the Databases family.

The component in this framework is available in all Talend products.

Basic settings

Database Type

Select the type of the database. The connection properties may differ slightly according to the database type selected.

Property Type

Select the way the connection details will be set.

  • Built-In: The connection details will be set locally for this component. You need to specify the values for all related connection properties manually.

  • Repository: The connection details stored centrally in Repository > Metadata will be reused by this component. You need to click the [...] button next to it and in the pop-up Repository Content dialog box, select the connection details to be reused, and all related connection properties will be automatically filled in.

Use an existing connection

Select this check box and in the Component List click the relevant connection component to reuse the connection details you already defined.

When a Job contains the parent Job and the child Job, if you need to share an existing connection between the two levels, for example, to share the connection created by the parent Job with the child Job, you have to:

  1. In the parent level, register the database connection to be shared in the Basic settings view of the connection component which creates that very database connection.

  2. In the child level, use a dedicated connection component to read that registered database connection.

For an example about how to share a database connection across Job levels, see Talend Studio User Guide.

This property is available only for the JavaDb database type.

DB Root Path

Browse to your database root.

This property is available only for the JavaDb database type.

ODBC Name

The name of the ODBC database.

Connection Type

Select the Oracle database connection type.

  • Oracle SID: select this connection type to uniquely identify a particular database on a system.

  • Oracle Service: select this connection type to use the TNS alias that you give when you connect to the remote database.

  • Oracle OCI: select this connection type to use Oracle Call Interface with a set of C-language software APIs that provide an interface to the Oracle database.

  • Oracle Custom: select this connection type to access a clustered database.

  • WALLET: select this connection type to store credentials in an Oracle wallet.

Username and Password

The database user authentication data.

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

Table name

The name of the table to be created.

Table Action

Select the action to be carried out on the table.

  • Create table: the specified table doesn't exist and gets created.

  • Create table if not exists: the specified table is created if it does not exist.

  • Drop table if exits and create: the table is removed if it already exists and gets created again.

Case Sensitive

Select this check box to make the table/column name case sensitive.

This property is available only for the HSQLDb database type.

Temporary Table

Select this check box if you want to save the created table temporarily.

This property is available only for the MySQL database type.

Create

Select the type of the table to be created.

  • SET TABLE: the table that does not allow duplicate rows.

  • MULTISET TABLE: the table that allows duplicate rows.

This property is available only for the Teradata database type.

Schema and Edit Schema

A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields.

  • Built-In: You create and store the schema locally for this component only. Related topic: see Talend Studio User Guide.

  • Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs. Related topic: see Talend Studio User Guide.

When the schema to be reused has default values that are integers or functions, ensure that these default values are not enclosed within quotation marks. If they are, you must remove the quotation marks manually.

For more details, see Verifying default values in a retrieved schema.

Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

  • View schema: choose this option to view the schema only.

  • Change to built-in property: choose this option to change the schema to Built-in for local changes.

  • Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion. If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the [Repository Content] window.
