tELTMSSqlMap Standard properties

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

The Standard tELTMSSqlMap component belongs to the ELT family.

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

Basic settings

Use an existing connection	Select this check box and in the Component List drop-down list, select the desired connection component to reuse the connection details you already defined. Information noteNote: 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: 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. 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.
JDBC Provider	Select the provider of the JDBC driver to be used, either Microsoft (the default, recommended) or Open source JTDS. When Microsoft is selected, you need to download the Microsoft JDBC Driver for SQL Server on Microsoft Download Center, unpack the downloaded zip file, choose a jar in the unzipped folder based on your JRE version, rename the jar to mssql-jdbc.jar and install it manually. For more information about choosing the jar, see the System Requirements information on Microsoft Download Center. When using this component with Datasource in Talend Runtime, you need to use the Open source JTDS driver. Information noteNote: This option defaults to Microsoft only if you have installed the R2020-06 Studio Monthly update or a later one delivered by Talend. For more information, check with your administrator.
ELT MSSql Map Editor	The ELT Map editor allows you to define the output schema and make a graphical build of the SQL statement to be executed. The column names of schema can be different from the column names in the database. If you have installed the R2021-06 Studio monthly update or a later one provided by Talend, an Enable/disable column name filter button is available on the upper right corner of the input and output tables in the Map editor. You can filter schema columns in an input or output table by clicking this button in the corresponding table and entering the search keyword in the field displayed.
Style link	Select the way in which links are displayed. Auto: By default, the links between the input and output schemas and the Web service parameters are in the form of curves. Bezier curve: Links between the schema and the Web service parameters are in the form of curve. Line: Links between the schema and the Web service parameters are in the form of straight lines. This option slightly optimizes performance.
Property type	Either Built-in or Repository. Built-in: No property data stored centrally. Repository: Select the Repository file where Properties are stored. The following fields are pre-filled in using fetched data.
Host	Database server IP address.
Port	Listening port number of DB server.
Database	Name of the database.
Username and Password	DB 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.

Advanced settings

Additional JDBC parameters	Specify additional connection properties for the DB connection you are creating. This option is not available if you have selected the Use an existing connection check box in the Basic settings.
Authenticate using Azure Active Directory	Select this option to use Azure Active Directory authentication when establishing the connection. See Azure AD Authentication for related information. This option is available when Microsoft is selected from the JDBC Provider drop-down list in the Basic settings view. Information noteNote: This option is available only if you have installed the R2020-05 Studio Monthly update or a later one delivered by Talend. For more information, check with your administrator.
tStatCatcher Statistics	Select this check box to gather the Job processing metadata at a Job level as well as at each component level.

Select this check box to gather the Job processing metadata at a Job level as well as at each component level.

Global Variables

Global Variables	ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box. A Flow variable functions during the execution of a component while an After variable functions after the execution of the component. To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it. For further information about variables, see Talend Studio User Guide.

Usage

Usage rule	tELTMSSqlMap is used along with a tELTMSSqlInput and tELTMSSqlOutput. Note that the Output link to be used with these components must correspond strictly to the syntax of the table name. Information noteNote: Note that the ELT components do not handle actual data flow but only schema information.
Dynamic settings	Click the [+] button to add a row in the table and fill the Code field with a context variable to choose your database connection dynamically from multiple connections planned in your Job. This feature is useful when you need to access database tables having the same data structure but in different databases, especially when you are working in an environment where you cannot change your Job settings, for example, when your Job has to be deployed and executed independent of Talend Studio. The Dynamic settings table is available only when the Use an existing connection check box is selected in the Basic settings view. Once a dynamic parameter is defined, the Component List box in the Basic settings view becomes unusable. For examples on using dynamic parameters, see Reading data from databases through context-based dynamic connections and Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic settings and context variables, see Talend Studio User Guide.
